The diagram shows the dimensions of a solid concrete patio in the shape of a right rectangular prism.

How much concrete was used to make the patio?

O A 1.44 m3
OB. 7.80 m
O c. 14.50 m
OD. 30.34 m

Answers

Answer: A

Step-by-step explanation: i multiplied all the sides

The quantity of concrete used to make the patio is 1.44 m³

Since the solid concrete patio is a right rectangular prism, to find the amount of concrete used in making the patio, we find its volume.

So, the volume of the patio, V = lbh where l = length of patio = 4.5 m, b = width of patio = 3.2 m and h = thickness of patio = 0.1 m

So, V = 4.5 m × 3.2 m × 0.1 m = 1.44 m³

The quantity of concrete used to make the patio equals the volume of the patio.

So, the quantity of concrete used to make the patio is 1.44 m³

Answers

Answer:

-25 and 4

Step-by-step explanation:

Two numbers that multiply to the value on top and add to the value on bottom

Value on top = -100

Value at bottom = -25

Numbers that multiply to give -100 = -10 × 10, -20 × 5, -25 × 4, - 50 × 2,

Of all the above, - 25 × 4 = -100

-25 + 4 = -21

Value at bottom = -25

Therefore, the two numbers are -25 and 4

-25 × 4 = -100

-25 + 4 = -21

Step-by-step explanation:

Divide 16 by 80 and you get 0.2 as an answer and to get a percent you move the decimal 2 places to the right to fet 20%

Isabel has completed 20 percent of the race of 80 miles.

What is the percentage?

A percentage is a quantity or ratio that, in mathematics, represents a portion of one hundred. It is one method for illustrating a relationship between two integers that has no dimensions.

Given, Isabel has ridden 16 miles of a bike course. The course is 80 miles long.  From the general formula of percentage:

For the percentage, we have to divide the value by the total value and then multiply the result by 100.

percentage of the course has Isabel ridden so far = (16/80) * 100

percentage of the course has Isabel ridden so far = 1/5*100

percentage of the course has Isabel ridden so far = 20%

Therefore, Isabel has ridden 20 percent of the course which is 80 miles.

Answer:

x = 125

Step-by-step explanation:

Kindly check the image below

The problem we are looking at gives us the value of two intercepted arcs and wants us to find x ( which is an interior angle )

According to the image we can find an interior angle by adding the two intercepted arcs and then dividing the sum by 2

( Note that we are not given the direct intercepted arcs  of x. We are given the intercepted arcs of x's supplementary angle )

That being said we need to find x's supplement in order to find x

Using the image below as a reference

x's supplement = [tex]\frac{70+40}{2}[/tex]

[tex]70 + 40 =110\\\frac{110}{2} =55[/tex]

So x's supplement = 55

Now to find x

Remember that supplementary angles have a sum of 180°

That being said we can find the missing angle (x) by subtracting the given angle (55) from 180

so x = 180 - 55

180 - 55 = 125

Hence x = 125
