The triangles are similar by SAS similarity and the similarity statement is ΔABC ~ ΔPQR.

We can determine the similarity of the triangles by checking if they satisfy the conditions of AA, SAS, or SSS similarity.

AA Similarity: If two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.

Looking at the triangles, we can see that angle A is congruent to angle P, and angle B is congruent to angle Q. However, we cannot conclude that the triangles are similar by AA similarity because we do not know if the third pair of angles are congruent.

SAS Similarity: If two pairs of sides of one triangle are proportional to two pairs of sides of another triangle, and the included angles are congruent, then the triangles are similar.

Looking at the triangles, we can see that:

AB is proportional to PQ (since AB/PQ = 4/5)

BC is proportional to QR (since BC/QR = 3/4)

Angle BAC is congruent to angle QPS (since they are vertical angles)

Therefore, the triangles are similar by SAS similarity. The triangle similarity statement is:

ΔABC ~ ΔPQR (by SAS similarity)

Answer:

  Horace

Step-by-step explanation:

You want to know if "base" refers to any particular side of a rectangle.

The formula for the area of a rectangle can be written ...

  Area = base × height

It can also be written ...

  Area = length × width

In each formula, the factors of the area refer to orthogonal dimensions of the rectangle. Any side of the rectangle can be considered to be the "base" or the "length" or the "width" or the "height". The other factor in the area formula is whatever dimension is orthogonal to that choice.

The commutative property of multiplication tells you that you get the same product if you reverse the order of the numbers.

So, you could have ...

  Area = AB·BC

or

  Area = BC·AB

If you insist that the fist of these numbers is the "base", then the base can be either AB or BC and the area will be the same.

The substitution property of equality tells you that you can substitute any equal values. Opposite sides of a rectangle are equal length, so either can be substituted for the other. In short, you can write the product for the area any of 8 ways:

  Area = AB·BC = AB·AD = BC·AB = AD·AB

  = CD·AD = CD·BC = AD·CD = BC·CD

If you want to distinguish between AB and BA, you can write this many more ways.

Horace seems to understand the fundamental interchangeability of the dimensions in the area formula. Horace has the right idea.

Bernice seems more attached to one particular understanding. We wonder what Bernice would call the "base" if the rectangle were drawn at a different angle to the grid.

Answer:

It's 45.

Step-by-step explanation:

Same as the last question :)

The area of a right triangle is given by the formula:

Area = 1/2 * base * height

Substituting the values given in the problem:

Area = 1/2 * 45 meters * 16 and 3/4 meters

To simplify the computation, we convert the mixed fraction 16 and 3/4 to an improper fraction:

16 and 3/4 = (16 * 4 + 3) / 4 = 67/4 meters

Substituting this value, we get:

Area = 1/2 * 45 meters * 67/4 meters

Simplifying:

Area = 843.75 square meters

Therefore, the area of the right triangle is 843.75 square meters.

Answer: 376 7/8

Step-by-step explanation: if you multiply the base and the height you'll get 754 3/4 since this is a triangle we are talking about it would be halved which would make it 376 7/8.

Answer:

  output = -3n +1

Step-by-step explanation:

Given an input/output table for a linear function, you want an expression for the output when the input is n.

The input values count up from 1, so we can consider the output values to be the terms of an arithmetic sequence.

The first term of the sequence is a1 = -2 (when n=1).

The common difference of the sequence is d = (-5 -(-2)) = -3.

The general (n-th) term of an arithmetic sequence is given by the formula ...

   an = a1 +d(n -1)

For the known values of a1 and d, we find the n-th term to be ...

  an = -2 +(-3)(n -1)

  an = -2 -3n +3 . . . . . . . eliminate parentheses

  an = -3n +1 . . . . . . . . collect terms

The term corresponding to an input value of n is ...

  -3n +1

Hence, the force that results has a magnitude of about 10.3 newtons (rounded to the nearest 10th of a newton).

"How much of a quantity" is the definition of magnitude. For instance, the amount of data can be utilized for assessing the speeds of a car and a bicycle. In addition, it can be used to express how far an object has come or how much weight it carries relative to its size.

The law of cosines, which connects a triangle's sides and angles, can be used to calculate the size of the resulting force:

A2 + B2 - 2ab*cos = C2 (C)

We can define the 8.6 newtons in this case as side a, the 3.5 newtons as side b, and the angle between them as C:

a = 8.6 N b = 3.5 N

C = 58°

By applying the law of cosines, we may determine the length of the resultant force or side c.

c = sqrt(105.36)

c ≈ 10.3

Hence, the force that results has a magnitude of about 10.3 newtons (rounded to the nearest 10th of a newton).

Answer:

tanx= -1 is the correct answer.

Therefore, the equation of the line passing through (0, -3) and (5, -3) is y = -3.

An equation is a mathematical statement that shows the equality between two expressions. It typically consists of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. The expressions on both sides of the equation are separated by an equals sign (=) and can be manipulated in various ways to find the value of the variable(s) that satisfies the equation.

Here,

To find the equation of the line passing through two points (x₁, y₁) and (x₂, y₂), we can use the point-slope form of a linear equation, which is:

y - y₁ = m(x - x₁)

where m is the slope of the line.

In this case, the two points are (0, -3) and (5, -3), so we have:

x₁ = 0, y₁ = -3

x₂ = 5, y₂ = -3

The slope of the line can be found using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

Substituting the values, we get:

m = (-3 - (-3)) / (5 - 0)

m = 0 / 5

m = 0

Since the slope m is zero, the line is a horizontal line.

To find the equation of the line, we can use the point-slope form with one of the points, say (0, -3). Substituting the values, we get:

y - y₁ = m(x - x₁)

y - (-3) = 0(x - 0)

Volume of the award is 510.25 square centimeter.

Volume is a measure of the amount of space that a three-dimensional object occupies. It is a physical quantity that is typically measured in cubic units, such as cubic meters (m³) or cubic centimeters (cm³).

The volume of an object is calculated by multiplying its three dimensions together. For example, the volume of a rectangular prism can be calculated by multiplying its length, width, and height. The formula for the volume of a rectangular prism is V = l x w x h, where V is the volume, l is the length, w is the width, and h is the height.

Given;

Height of the conical part, h=12cm

Radius of the conical part, r=5cm

Height of the cylindrical part, H=2.5cm

Total volume of award=Volume of conical part+ Volume of cylindrical part

=πr²h/3+πr²H

=π×5²×12/3+π×5²×2.5

Ariel got a job at a restaurant and needed to purchase 2 shirts and 2 pairs of pants.

Let's use the variable "x" to represent the number of shirts Ariel buys and "y" to represent the number of pants she

buys.

Then, we can write the following system of inequalities:

2 ≤ x ≤ ∞ (Ariel needs at least 2 shirts)

2 ≤ y ≤ ∞ (Ariel needs at least 2 pairs of pants)

7.50x + 18y ≤ 150 (Ariel wants to spend no more than 150)

Now, we can graph the system of inequalities on a coordinate plane to find the feasible region, which represents all the possible combinations of shirts and pants that satisfy the given constraints.

The feasible region is shaded in the graph below:

graph {(150-7.5 × x)/18}

As you can see from the graph, the feasible region is a quadrilateral with vertices at (0, 8.33), (2, 7), (8, 3), and (25, 0).

This means that Ariel can buy any combination of shirts and pants within this region and still meet her requirements.

To find the optimal solution, we can simply check the corner points of the feasible region and see which combination gives us the most value for our money.

For example, if Ariel buys 2 shirts and 2 pants (i.e., the point (2, 2) on the graph), she will spend:

7.50(2) + 18(2) = 51

This is within her budget of 150 and meets her requirement of at least 2 shirts and 2 pants.

Therefore, the answer is: Ariel should buy 2 shirts and 2 pairs of pants.

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

Let's assume that there were x grapes in the container at first.

Arianna ate 0.45 of the grapes, which means she ate 0.45x grapes.

Alex ate 35% of the grapes, which means he ate 0.35x grapes.

The total number of grapes eaten is the sum of what Arianna and Alex ate:

0.45x + 0.35x = 0.8x

This means that 0.8x grapes were eaten, and the number of grapes left is x - 0.8x = 0.2x.

We know that there were 18 grapes left, so we can set up an equation:

0.2x = 18

Answer:

To find the percentage of residents who participated in the recycling drive, we need to divide the number of participants by the total number of residents and then multiply by 100 to get the percentage. Total number of residents in Percy's town = 5,320 + 1,680 = 7,000 Number of residents who participated = 5,320 Percentage of residents who participated = (Number of participants / Total number of residents) x 100 = (5,320 / 7,000) x 100 = 76% Therefore, 76% of the residents of Percy's town participated in the recycling drive.

Answer:

The correct answer is 76%.

Step-by-step explanation:

To find the percentage of Percy's town that participated in the recycling drive, we must divide the number of people that participated by the total number of residents.

To do this, we should first find the total number of residents. Since residents either participated or did not participate, the total number of residents is the sum of these two values. This is modeled below:

Total number of residents = 5,320 + 1,680 = 7,000 total residents

Now, we can continue with the percentage calculation.

% participation = # of participants/# of residents * 100

% participation = 5,320/7,000 * 100

% participation = 76%

Therefore, we can conclude that 76% of Percy's town participated in the recycling drive.

You would first start by solving for the x value. You would do 6x-7=2x+5, then start factoring out number and variable until the variable is on 1 side and the number are on the other, so it'd be 4x=12. After you would calculate for the x which is 3, which you did, then you would plug that back into the values. You'd plug 3 into 2(x)+5 which simplifies down to 6+5 which is 11 and since DB is half of AB you multiply by 2 to get 22.

1.  Perimeter of AARG = 1.6 × 4.4 cm = 7.04 cm

2.  The measure of SBH is 162°.

3. Area of AARG = 2.56 × 0.8 cm² = 2.048 cm²

4. The length of the circumference of circle B is approximately 13.01 cm.

The circumference of a this double shape's perimeter is its total length. In other terms, it is the total length of all a shape's sides. For instance, the circumference of a circle is equal to the distance around its outside, or circumference, whereas the perimeter of a rectangle may be computed by combining the measurements of all four sides.

To solve this problem, we can use the fact that all circles are similar. This means that corresponding lengths of the circles are proportional. In particular, if the ratio of the radii of two circles is k, then the ratio of their circumferences is also k, and the ratio of their areas is k².

Let's start with finding the radius of the larger circle. Since OB/OA = 2.25, we can write:

OA + AB = OB

OA + 1 = 2.25 OA

OA = 1 / 1.25 = 0.8

Therefore, the radius of the larger circle is 0.8 cm. Since the circles are similar, the ratio of the radii is 0.8/0.5 = 1.6.

1. The perimeter of ABSH is proportional to the radius of the circle, so we have:

Perimeter of ABSH = 1.6 × Perimeter of AARG = 1.6 × 4.4 cm = 7.04 cm

2. Let x be the measure of SBH. Then we have:

RAG + SBH + HBS = 360°

108° + x + 90° = 360°

x = 162°

Therefore, the measure of SBH is 162°.

3. The area of ABSH is proportional to the square of the radius of the circle, so we have:

Area of ABSH = 1.6² × Area of AARG = 2.56 × 0.8 cm² = 2.048 cm²

4. The circumference of circle B is proportional to the radius of the circle, so we have:

Circumference of circle B = 1.6 × Circumference of circle A ≈ 1.6 × 8.13 cm ≈ 13.01 cm

Therefore, the length of the circumference of circle B is approximately 13.01 cm.

The work required to pump the water out of the hemispherical tank is 5,930,818.125 ft-lb.

To find the work required to pump the water out of the hemispherical tank, we need to consider the following steps:
Step 1: Determine the volume of the hemispherical tank.
The formula for the volume of a hemisphere is (2/3)πr³,

where r is the radius.

Given the radius is 13 ft, we can calculate the volume as follows:
Volume = (2/3)π(13³)

= (2/3)π(2197)

= 14603.86 ft³.
Step 2: Calculate the weight of the water in the tank.
Given the water weighs 62.5 lb/ft³, we can determine the weight of the water in the tank by multiplying the volume by the water weight:
Water weight = Volume × Weight/ft³

= 14603.86 ft³ × 62.5 lb/ft³

= 912741.25 lb.
Step 3: Determine the average height at which the water must be pumped out.
Since the tank is hemispherical, the average height for pumping the water is half the radius (13 ft).

So, the average height is:
Average height = 13 ft ÷ 2 = 6.5 ft.
Step 4: Calculate the work required to pump the water out of the tank.
Work = Weight × Distance × Force of gravity.
