what is the lateral surface area of a rectangular prism in square inches.

Answers

Answer:

When a prism has its bases facing up and down, the lateral area is the area of the vertical faces.

(For a rectangular prism, any pair of opposite faces can be bases.)

The lateral area of a right prism can be calculated by multiplying the perimeter of the base by the height of the prism.

Toni’s school day is 8 hours. She has 8 classes that
are 3/4 hour long. How many hours is Toni not in
class while she is at school?

A. 1 1/2
B. 2
C. 3/4
D. 9

Answers

The answer is B. 3/4 of an hour is 45 minutes, and 1 hour is 60 minutes, so we take the remaining 15 minutes, multiply it by 8 and that gives us 120. We know 60 times 2 is 120, so that gives us 2 hours.
The answer is B. 2 hours

What is the total area of this composite figure rounded to the nearest hundredth? 18.53 ft 2 39.53 ft 2 20.07 ft 2 43.07 ft 2

Answers

Answer:

39.53 ft^2

Step-by-step explanation:

A = l*w

= 12*3 = 36

A = 1/2 pir^2

The dm is 3, the rs is 3/2

=1/2 pi* (3/2)^2

= 1/2 *3.14 * 9/4

1. Two of the angles of a triangle measure 15° and 150°. Classify the triangle.
A. Equilateral
B. Scalene
C. Isosceles

Answers

Its Isosceles

cause a triangle must always add up to 180 if you are finding the angles and they give you 15 and 150 if you add that you get 165 and i you subtract that from 180 you get 15 and a isosceles has 2 equal angles

Answer:

Isosceles

Step-by-step explanation:

An isosceles triangle is a triangle with two equal sides, as well as two equal angles. So take 150, add it to 15. You get 165. Take 180, then subtract 165. You get 15, and since you know another angle is 15, you have an isosceles triangle.

x = 7

Step-by-step explanation:

The 2 angles are adjacent and sum to 180° , that is

11x + 8 + 12x + 11 = 180

23x + 19 = 180 ( subtract 19 from both sides )

23x = 161 ( divide both sides by 23 )

x = 7

A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x2+12x+10) ft3 and the volume of the water in the shallow end can be represented by (4x2−100)ft3.

Write two different equivalent expressions ("simplified" and "simplified") that represents the total volume of the water in the pool in ft3.

Answers

Answer:

(2x2+12x+10) = (4x+12x+10) = (16x+10) ft³

(4x2−100) = (8x-100) ft³

(8x-100 + 16x+10 + x) > (24x-90)(8x-100 + 16x+10 - x) < (24x-90)

5.The measure of smaller angle is 87 degrees.

Step-by-step explanation:

Consider the provided information.

The provided angles are 3x degree and 2x + 25 degree.

Two angles are said to be Supplementary angles if their sum is 180 degree.

It is given that the provided angle are supplementary angles, thus

3x + 2x + 25 = 180

5x + 25 = 180

5x  = 180 - 25

5x  = 155

x = 31

Now, substitute the value of x in first angle i.e 3x.

3(31) = 93

Substitute the value of x in the second angle i.e 2x + 25

2(31) + 25 = 62 + 25 = 87

Hence, the measure of smaller angle is 87 degrees.

4,712 yards.

We can use the formula V=1/3hπr² to figure out what the volume of the cone is.

So using the numbers provided the new equation would be V=1/3(20)π15², which would come out to 4,712 yards.

Find the missing side. Round to the nearest tenth when necessary.

Answers

Answer:

15.6

Step-by-step explanation:

Because it is a right triangle, you can use the Pythagorean Theorem. The theorem is c^2 = a^2 + b^2, with c being the hypotenuse, and a and b being the legs. So plug in the values and you will get 18^2=9^2 + b^2. Solve for b and you will get 15.6.

Answer:

x=15.59

Step-by-step explanation:

using the pythagorean theorem we know a²+b²=c²

also that c²-a²=b². in this case we're using the second one. c² is 18², and a² is 9². 18²-9² is 243. we then find the square root of that number to get x (b²). x=15.59 rounded to the nearest hundreth.
