The area of one stretcher course of 18 concrete blocks is 467 1/2 square inches.

What is Area of stretcher course ?

To find the area of a stretcher course, you need to know the dimensions of the bricks or blocks, the number of bricks or blocks in the course, and the thickness of the mortar joints between them. The formula for the area of a stretcher course is:

Area of stretcher course = (Number of bricks or blocks) x (Length + Width) x Height

where Length is the length of each brick or block, Width is the width of each brick or block, and Height is the height of each brick or block.

According to the question :
To find the area of one stretcher course of 18 concrete blocks, we first need to calculate the total length and height of the course, taking into account the thickness of the mortar joints.

Length of the course = 18 blocks x 6 3/8 inches per block = 114 3/4 inches

Total width of the course = 17 mortar joints x 1/8 inch per joint = 2 1/8 inches

Height of the course = 4 inches

To calculate the area of the stretcher course, we need to multiply the length, width, and height of the course:

Area of stretcher course = Length x Width x Height

Area of stretcher course = (114 3/4 + 2 1/8) x 4

Area of stretcher course = (116 7/8) x 4

Area of stretcher course = 467 1/2 square inches

Therefore, the area of one stretcher course of 18 concrete blocks is 467 1/2 square inches.

b equal for the top of the bookcase to have the correct area= 5 cm2

A solid object's surface area is a measurement of the total area that the surface of the object takes up.

The definition of arc length for one-dimensional curves and the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is the sum of the areas of its faces, are both much simpler mathematical concepts than the definition of surface area when there are curved surfaces.

A smooth surface's surface area is determined using its representation as a parametric surface, such as a sphere.

This definition of surface area uses partial derivatives and double integration and is based on techniques used in infinitesimal calculus.

Henri Lebesgue and Hermann Minkowski at the turn of the century sought a general definition of surface area.

L × b = 300

b = 300 / L

b = 300 / 60 = 5

Hence, b equal for the top of the bookcase to have the correct area= 5 cm2.

The term "concatenation is associative" means that if we concatenating sequences or strings, the order in which it is performed does not matter.

Basically, in mathematics, concatenation is the operation of joining two or more sequences or strings together. The meaning of "concatenation is associative" is that when concatenating three or more sequences or strings, the order in which the concatenation is performed does not matter.

This means that we can group the concatenation of any number of sequences or strings in any way we like, and the result will always be the same.

For example, given three strings A, B, and C, the following expressions would give the same result:

(A + B) + C

A + (B + C)

All these is because the order of concatenation does not affect the final outcome. The property of associativity is important in many areas of mathematics and computer science, such as algebra, programming, and database design.

Answer:

7.14 years

Step-by-step explanation:

We can use the formula for simple interest to solve this problem:

Simple Interest = Principal x Rate x Time

where the principal is the initial investment, the rate is the annual interest rate, and the time is the number of years.

We know that Geneva wants to save $12,000, and she already has $8,000 from her bonus, so she needs to earn an additional $4,000 in interest. We can use this amount as the principal in the formula.

Simple Interest = $4,000

Principal = $8,000

Rate = 0.07 (7% expressed as a decimal)

Plugging in the values, we get:

$4,000 = $8,000 x 0.07 x Time

Simplifying, we get:

Time = $4,000 / ($8,000 x 0.07)

Time = 7.14 years (rounded to the nearest hundredth)

Therefore, Geneva will need to leave her money in the account for approximately 7.14 years to accumulate the $12,000 she needs

Answer:

the equation of line BC is y = (-7/5)x + (48/5).

Step-by-step explanation:

To find the equation of the line that passes through points B and C, we first need to determine the coordinates of point C. Since the angle at B is a right angle, we can use the slope of line AB to find the slope of line BC.

The slope of line AB is:

mAB = (yB - yA) / (xB - xA)

= (4 - (-1)) / (4 - (-3))

= 5/7

Since lines AB and BC are perpendicular, the slope of line BC is the negative reciprocal of the slope of line AB:

mBC = -1 / mAB

= -7/5

Now we can use the point-slope form of the equation of a line to find the equation of line BC. We can use point B as the known point, since we already know its coordinates:

y - yB = mBC(x - xB)

Substituting the values we have:

y - 4 = (-7/5)(x - 4)

Expanding and simplifying:

y - 4 = (-7/5)x + (28/5)

y = (-7/5)x + (48/5)

Answer:

Step-by-step explanation:

To calculate the company's debt ratio, we need to know its total liabilities and total assets. We can use the total assets turnover ratio to calculate the company's total assets:

Total assets turnover = Sales / Total Assets

1.04 = R6,500,000 / Total Assets

Total Assets = R6,500,000 / 1.04 = R6,250,000

Since the company is financed entirely with debt and common equity, its total liabilities are equal to its total debt. We can use the return on equity (ROE) formula to calculate the company's total equity:

ROE = Net Income / Total Equity

0.14 = R217,000 / Total Equity

Total Equity = R217,000 / 0.14 = R1,550,000

Now, we can calculate the company's debt ratio:

Debt Ratio = Total Debt / Total Assets

Debt Ratio = (Total Assets - Total Equity) / Total Assets

Debt Ratio = (R6,250,000 - R1,550,000) / R6,250,000

Debt Ratio = R4,700,000 / R6,250,000

Debt Ratio = 0.752 or 75.2%

Therefore, the company's debt ratio is 75.2%.

To calculate the amount of money Glados will have in 5 years with simple interest, we can use the formula:

A = P(1 + rt)

where A is the final amount, P is the principal (initial amount), r is the annual interest rate as a decimal, and t is the time in years.

In this case, P = $700, r = 0.079 (since 7.9% is 0.079 as a decimal), and t = 5 years. Substituting these values into the formula, we get:

A = 700(1 + 0.079 x 5)

A = 700(1 + 0.395)

A = 700(1.395)

A = $976.50

Therefore, Glados will have $976.50 in 5 years, to the nearest penny.

The following sets of numbers could represent the three sides of a

triangle is {7, 15, 20}.

The set of numbers {7, 15, 20} could represent the three sides of a triangle, but the other sets of numbers do not satisfy the triangle inequality theorem, which states that the sum of any two sides of a triangle must be greater than the third side. Checking the sets of numbers:

For {7, 15, 20}, 7 + 15 > 20, 7 + 20 > 15, and 15 + 20 > 7, so they satisfy the triangle inequality theorem and could represent the sides of a triangle.

For {7, 16, 23}, 7 + 16 < 23, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.

For {11, 22, 35}, 11 + 22 < 35, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.

For {5, 17, 22}, 5 + 17 < 22, so they do not satisfy the triangle inequality theorem and cannot represent the sides of a triangle.

Step-by-step explanation:

To find the value of t, we can use the information given about the temperature at two different elevations and use the formula for a linear equation.

Let's assume that the temperature decreases by tº Fahrenheit for every additional 100 feet above sea level, where t is the constant we want to find.

Then, using the two points given:

- (8000, 65) where 65 is the temperature in Fahrenheit at 8000 feet above sea level

- (10,500, 15) where 15 is the temperature in Fahrenheit at 10,500 feet above sea level.

We can calculate the slope of the line connecting these two points:

slope = (15 - 65) / (10,500 - 8,000) = -25

The slope of the line represents the amount that the temperature decreases per unit increase in elevation. In this case, we've found that the temperature decreases by 25 Fahrenheit for each increase in elevation of 1000 feet.

To find the value of t, we need to express the slope in terms of the decrease in temperature per 100 feet of elevation. We can do this by dividing the slope by 10:

t = slope / 10 = -2.5

Therefore, the value of t is -2.5.
