Answer:

8: 73.2 cm

10: 738 mm

Step-by-step explanation:

8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm

10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm

Answer:

8: 73.2

10: 738

Step-by-step explanation:

Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]

where a and b = base lengths and h = height

For #8

These are the given dimensions

Base 1 = 4.5

Base 2 = 7.5

Height = 12.2

All we have to do is plug in the values into the formula

So....

[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]

Hence the answer is 73.2cm²

For #10

Once again all we have to do is plug in the values into the formula

[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]

Hence the answer is 738

Answer:

36.8/2.8 = 16

Expression 1 = 368/28

Expression 2 = 3.68/.28

Step-by-step explanation:

If you move the decimal the same on both numbers of a division problem the answer stays the same.

Answer:

1. 32÷2, 64÷4

2. 16

Step-by-step explanation:

Expression 1:

32÷2=16, and 64÷4=16.

Expression 2:

Change the divisor 2.3 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

368 ÷ 23 = 16

and therefore:

36.8 ÷ 2.3 = 16

Both calculated to 0 decimal places.

Answer:

A. 44 inches

Step-by-step explanation:

1] Add the numbers given 6 + 6 + 11 + 11 = 34 (because you are trying to find the perimeter)

2] Subtract 6 from 11,  11 - 6 = 5

3] do the same to the top 11 - 6 = 5

4] then add the new numbers together along with the given ones. 6 + 6 + 11 + 11 + 5 + 5 = 44

Irrational (I think)

Answer:

Answer:

Answer: 20%

To find the percentage of a fraction just do the top number divided by the bottom you get 0.2 and 0.2 is equal to 20% so 20% is the answer hope that helps!

Answer:

1/5 = 20%

Step-by-step explanation:

1/5 = 1 ÷ 5 obviously

So figure out 1 ÷ 5

Your answer would be 0.2

Now, when converting a number to a percent you would multiply it by 100

0.2 × 100 is

20%

I hope I helped! :)

Answer:

7/2 feet

Step-by-step explanation:

Volume of Right Rectangular Prism: V = w * h * l

You are given the volume, and the base (which would include l and w)- and are told to find h.

70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)

70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)

7/2 feet = h

The height will be 7/2

a. Common Denominator = 8

[tex]\frac{1}{8\\}[/tex] * [tex]\frac{1}{1}[/tex] = [tex]\frac{1}{8}[/tex] /// [tex]\frac{1}{2}[/tex]*[tex]\frac{4}{4}[/tex]=[tex]\frac{4}{8}[/tex]

b. Common Denominator = 40

[tex]\frac{1}{8}[/tex] * [tex]\frac{5}{5}[/tex] =  [tex]\frac{5}{40}[/tex] ///  [tex]\frac{9}{5}[/tex] * [tex]\frac{8}{8}[/tex] =  [tex]\frac{72}{40}[/tex]  

c. Common Denominator = 24

[tex]\frac{1}{8}[/tex] * [tex]\frac{3}{3}[/tex] =  [tex]\frac{3}{24}[/tex] ///  [tex]\frac{11}{6}[/tex] * [tex]\frac{4}{4}[/tex] =  [tex]\frac{44}{24}[/tex]

Answer:

8.88

Step-by-step explanation:

I believe it is 8.88 becuase this question is asking to find 90% pf that number.  

What do you need to do?

you have to make a proportion.

8/x 90/ 100

You would now cross multiply. 90* x = 90x 8*100= 800

the equation you would need is 90x = 800. divide them and you get 8.88.

ROUNDED: you get 9.

I believe this is correct sorry if it was incorrect.
