Step-by-step explanation:

88 is the correct answer.

The height of the prism is 8 feet.

Surface area is the amount of space covering the outside of a three-dimensional shape.

Given : sum of length of legs = 42 feet

Surface Area of trapezoid = 1/2* (Sum of opposite side)* height

                                            = 1/2* 42*18

                                             = 468

Perimeter = 15+37+ 42

                = 94 feet

Total Area= 2 ( Area of base) + pH

       1688   = 936 + 94H

       H= 8 feet.

Thus, height of the prism is 8 feet.

Answer:

11.2

Step-by-step explanation:

Radius = 5.6
Diameter = r x 2
               = 5.6 x 2
               = 11.2

Answer:

11.2 feet

Step-by-step explanation:

To find the diameter of a circle from the radius you must multiply the radius by 2 so the formula would look like r x 2= D  and the equation would look like 5.6 x 2=D = 11.2

Answer:

34

Step-by-step explanation:

180 since it is supplementary

then minus 100 which is 80 then minus 12 which is 68 then half that which is 34

Answer:

X°+X°+12°+100°=180°{Being strangle angle}

2x°+112°=180°

2x=180°-112°

2x= 68°

X=68°/2

X=34°

1/10 is the reciprocal of 10.

A number system is defined as a system of writing to express numbers.

Reciprocal is simply defined as the inverse of a value or a number.

If n is a real number, then its reciprocal will be 1/n.

In other words the reciprocal of a number is simply "1" divided by that number. So, the reciprocal of 10 is 1/10.

To see why this is the case, you can think of division as the opposite of multiplication. If you multiply 10 by its reciprocal, you should get the number 1. That is:

10 x (1/10) = 1

So, 1/10 is the reciprocal of 10.

Answer:

14 + 15 + 16 = 45 . Let the three consecutive integers be x, x+1 and x+2. Therefore the numbers would be 14, 15 & 16. answer: 14, 15 and 16.

Step-by-step explanation:

Call n the first integer so you get:

[tex]n + ( n + 1 ) + ( n + 2 ) = 45[/tex]

[tex]3 n + 3 = 45[/tex]

[tex]3 n = 42[/tex]

[tex]n = 14[/tex]

Answer: 165 Sqare feet.

Front  and back triangles-

Basically do as if finding the area of a square. Since thier two triangles it would be and extra step to divide in half ~ 5x6=30

Side Rectangles

Multiply the length and width. Since there is two sides times it by 2.

6.5 x 7 = 45.5 | 45.5 x 2 = 91 square feet

The bottom

Do the same thing as the sides, Length times width. ~ 5x7 = 35

Total - Adding

Now add them all together, (30+91+35) which equals 165 square feet.

Answer:

Step-by-step explanation:

b and c

The distance between two points is D and E, E and F, C and D, A and B, B and C, when the points are arranged in increasing order.

Discover the distance formula, a Pythagorean theorem application, to determine the separation between two places. To get the separation between any two points, we can rewrite the Pythagorean theorem as

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

In geometry, distances are always positive unless the points are exactly adjacent. The distance between A and B is equal to the distance between B and A.

Since, The distance between two points (x₁ , y₁) and (x₂, y₂) is,

⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²

Hence, The distance is provided in the following equation as

A and B are √39 miles apart.

B and C are √41 miles apart.

C and D are 5 miles apart.

D and E are 4 miles apart.

E and F are √17 miles apart.

14

the second one is

Simplify the expression.

−3

Answer:

5-(-9) = 14

-6-(-3) = -3

Step-by-step explanation:

So for the first one -1-(6), when you have two negatives next to each other then it turns into a plus. So when it turns into a plus. So when it turns into a plus we will have 5+9. And here we have the same signs so we are gonna add and 5+9=14. So the answer is 14.

Now for the second one -6-(-3), the same thing when you have two negatives next to each other then it turns into a plus. And when it turns into a plus we will have -6+3. Now although there is a plus sign we are not gonna add because both number do not have the same sign. So we are gonna subtract and take the sign of the bigger number. And now -6+3=-3 so our answer is -3.
