The blanks of the number pyramid puzzle can be filled with numbers calculated below.

A number pyramid puzzle is a type of mathematical puzzle where a pyramid-shaped grid of numbers is given, with some of the numbers missing.

Check the attached image for labeling. Since each number is the product of the two numbers directly beneath it. We can say:

m = -4 * 0.5 = -2

k = 0.5 * 1/8 = 1/16

x * (-1/8) = 8

x = 8/(-1/8)

x = -64  

y = x * 1/8

y = -64 * 1/8

y = -8

j = m * k

j =  -2 * 1/16 = -1/8

p = -48 * m

p = -48 * (-2) = 96

n = y * 8

n = -8 * 8 = -64

t = p * j

t = 96 * (-1/8) = -12

w = -1/2 * n

w = -1/2 * (-64) = 32

c = t * 1/16

c = -12 * 1/16 = -3/4

u = 1/16 * w

u = 1/16 * 32 = 2

d = c * u

d = -3/4 * 2 = -3/2

The parallelogram ABCD's congruency can be proven using Side-Angle-Side (SAS) congruence theorem.

Prove that ΔABC ≅ ΔDCB using the Side-Angle-Side (SAS) congruence theorem.

Given that ABCD is a parallelogram, AB || CD and BC || AD. Therefore, ∠ABC ≅ ∠DCB and ∠ACB ≅ ∠DCA because they are corresponding angles.

AB ≅ CD and BC ≅ AD because opposite sides of a parallelogram are congruent.

Lastly, AC ≅ AC because it is a shared side between the two triangles.

Therefore, the following congruent parts:

∠ABC ≅ ∠DCB (by corresponding angles)

AB ≅ CD (by opposite sides)

BC ≅ AD (by opposite sides)

AC ≅ AC (shared side)

The SAS congruence theorem concludes that ΔABC ≅ ΔDCB.

Therefore , the solution of the given problem of percentage comes out to be the firm expects that each warranty it sells will be worth $1.41.

In statistics, "a%" is used to refer to a figure or number that is expressed as a percentage of 100. Additionally rare are the forms that "pct," "pct," or "pc". It is typically represented by the symbol "%," though. Additionally, there are not any indicators and the proportion of each item to the overall amount is flat. Since percentages typically add up to 100, they are essentially integers. Either the expression "fraction" or the symbol for percentage (%) .

Here,

The price to substitute each item is $200. The anticipated price for each component is thus:

Expected cost per product equals Replacement cost x Failure Probability

=> Cost per product anticipated = 0.008 x $200

=>  Expected price per item is $1.60.

So, the following is the anticipated value of each warranty sold:

Expected worth of the warranty = Failure rate x (Replacement cost - Cost of warranty)

=>   Expected guarantee value = 0.008 * ($200 - $22 - $1.60).

=>  Expected guarantee value = 0.008 * $176.40

=>  Expected warranty worth is $1.41

As a result, the firm expects that each warranty it sells will be worth $1.41.

Answer:

To find all values of x for which f(x) = 26, we can set up the equation:

8x + 15/x = 26

Multiplying both sides by x, we get:

8x^2 + 15 = 26x

Bringing all the terms to one side, we get:

8x^2 - 26x + 15 = 0

We can factor this quadratic equation using the factoring method or by using the quadratic formula. Here, we will use the factoring method:

8x^2 - 26x + 15 = 0

(4x - 3)(2x - 5) = 0

Setting each factor equal to zero and solving for x, we get:

4x - 3 = 0 OR 2x - 5 = 0

4x = 3 OR 2x = 5

x = 3/4 OR x = 5/2

Therefore, the values of x for which f(x) = 26 are x = 3/4 or x = 5/2.

Using the right cone formula we know that the surface area is 1281.77638m³ respectively.

An axis that is perpendicular to the base plane defines a right circular cone. By rotating a right triangle around one of its legs, we may create a right cone.

The right circular cone in the illustration has an axis that is perpendicular to the base and a circular base with a radius r.

So, the formula for the surface area of the right cone is as follows:

πr(r+√h²+r²)

We have the values: r = 13m and h = 13m

Now, insert values as follows:

= πr(r+√h²+r²)

= π13(r+√13²+13²)

= 1281.77638

b=7 & c=7√2

Step-by-step explanation:

b=7 as it is an isosceles triangle

now using Pythagoras theorem,

(c)^2= (7)^2+(7)^2

⇒(c)^2= 49+49

⇒(c)^2= 98

⇒c= √98

⇒c=7√2

Answer:

Step-by-step explanation:

You want the missing side lengths in an isosceles right triangle with one side given as 7.

The two congruent acute angles tell you this right triangle is isosceles. That means sides 7 and b are the same length:

  b = 7

The hypotenuse of an isosceles right triangle is √2 times the side length:

  c = 7√2

__

Additional comment

You can figure the hypotenuse using the Pythagorean theorem if you haven't memorized the side relations of this "special" right triangle.

  c² = 7² + b²

  c² = 7² +7² = 2·7²

  c = √(2·7²) = 7√2

The side length ratios for an isosceles right triangle (angles 45°-45°-90°) are 1 : 1 : √2.

The other "special" right triangle is the 30°-60°-90° triangle, which has side length ratios 1 : √3 : 2.

If the anticipated claim outcome actually occurs, it will be feasible to get in connection with the entity once more; if not, both crucial systems will undoubtedly miss the statement.

Here,

The pressure of the gas inside the can will rise as the temperature rises. This is due to the fact that the gas particles inside the can will accelerate and acquire kinetic energy, causing them to collide with the can's walls more frequently and more violently.

The pressure rises as a result of these collisions' greater power per unit area.

The Ideal Gas Law, which says that PV = nRT, where P is tension, V is volume, n is the number of moles of gas,

R is the optimal gas constant, and T is temperature in Kelvin, describes this relationship between pressure and temperature.

The answer of the given question based on the graph and the function the answer are,

a) Demi's speed is decreasing over time.

b) Demi's speed decreases  from approximately 8.5 miles per hour to 5 miles per hour and  Demi's speed decreases from approximately 6 miles per hour to 3 miles per hour.

Speed is measure of how fast object is moving, or  rate at which it covers  certain distance over time. Mathematically, speed is calculated as distance traveled divided by time it takes to travel that distance.

a. When the function is decreasing, Demi's speed is decreasing over time. This means that she is running more slowly as time goes on. On the graph, this will be shown as a downward slope or a negative slope. The steeper the slope, the faster her speed is decreasing.

b. From the graph, we can see that the function is decreasing in two intervals. The first interval is from 0 to 5 minutes, where Demi's speed decreases from approximately 8.5 miles per hour to 5 miles per hour. The second interval is from 10 to 15 minutes, where Demi's speed decreases from approximately 6 miles per hour to 3 miles per hour.

Answer:

  (a)  Figure 3

  (b)  66.2 meters per second

Step-by-step explanation:

You want to know the figure that shows the best fit of a curve to the data, and you want to know the value of the curve when x = 8 seconds.

The fit is best when the difference between the data points and the curve is minimized. Often the sum of the squared differences is the metric that is minimized when the fit is best.

The gaps between the data points and the curve shown are greatest in Figures 1 and 2, so Figure 3 has the best fit.

The speed is estimated by the equation of the curve of best fit as ...

  y = 0.6x² +2.1x +11

A slight rearrangement can make this easier to evaluate:

  y = (0.6x +2.1)x +11

For x=8, the value of y is ...

  y = (0.6·8 +2.1)·8 +11 = 6.9·8 +11 = 66.2

The predicted speed at 8 seconds is 66.2 meters per second.

Answer:

Step-by-step explanation:

To calculate this, we need to use the formula for future value of an annuity:

FV = PMT x ((1+i)^n - 1)/i

Where:

PMT = the periodic payment (or deposit)

i = the interest rate per period

n = the number of periods

In this case, there are three deposits:

- R3,600 deposited one year ago

- R5,000 deposited today

- R7,500 to be deposited next year

We can calculate the future value of each of these deposits separately, and then add them together to get the total future value:

Future value of R3,600 deposited one year ago:

n = 4 (4 years until the equipment purchase)

i = 7% per year

PMT = R3,600

FV = R3,600 x ((1+0.07)^4 - 1)/0.07 = R4,661.07

Future value of R5,000 deposited today:

n = 3 (3 years until the equipment purchase)

i = 7% per year

PMT = R5,000

FV = R5,000 x ((1+0.07)^3 - 1)/0.07 = R6,885.02

Future value of R7,500 to be deposited next year:

n = 2 (2 years until the equipment purchase)

i = 7% per year

PMT = R7,500

FV = R7,500 x ((1+0.07)^2 - 1)/0.07 = R8,733.63

Total future value = R4,661.07 + R6,885.02 + R8,733.63 = R20,279.72

Therefore, there will be R20,279.72 available when the family is ready to buy the equipment, assuming a 7% rate of return on the investment.

We have shown that ΔABC ~ ΔDBE because the corresponding angles are congruent and the corresponding sides are proportional.

The relationship between two quantities is constant for all values when they are proportional, which indicates that as one quantity rises, the other rises as well.

We must demonstrate that the respective angles of the two triangles are congruent and the corresponding sides are proportionate in order to demonstrate that ABC DBE.

To begin with, we can relate the sides of the two triangles using the following equation AB BE = CB BD. Let x, y, and z all be equal to AB. Next, we have:

x · BE = y · z (substituting the given values)

y/x = BE/BD (dividing both sides by BD and then by x)

Now, we can utilise the knowledge that a triangle's angles sum to 180 degrees to get the length of ABC:

ACB - 180° = ABC (from the given triangle ABC)

ABC = 180 degrees - BDE (corresponding angles)

The measure of BDE can then be determined using the connection between the sides that we discovered earlier:

y/x = BE/BD (from above)

BE/DE = y/(x+z) (substituting z = BD)

BDE is equal to tan(y/(x+z)) Inverse tangent is used.

Now, we can use the fact that a triangle's angles sum to 180 degrees to determine the size of the DBE:

DBE = 180°, BDE, and BED

DBE is equal to 180 - tan(y/(x+z)) - ∠BED (substituting the angle measure we just found) (substituting the angle measure we just found)

DBE is equal to 180° - tan(y/(x+z)) - tan(y/z) (using inverse tangent again)

tan(z(y+x)/(xz-yz)) = DBE (using the tangent of the sum formula)

In order to demonstrate that the sides of the two triangles are proportional, we can once more use the relationship between the sides:

BE/BD = AB/CB (from the given equation and simplification)

Y/x = AB/CB (from the relationship between the sides)

As a result, we have demonstrated that ABC DBE since the associated angles and sides are congruent and proportionate, respectively.
