Answer:

12.5

Step-by-step explanation:

25%=.25

.25*50=12.5

Answer: 12.5

Step-by-step explanation: If its a percent always divide the number by 100.

EX: 25% of 50

25%=0.25

0.25x50=12.5

Answer:

1. 18 cm sq

2. 140 in sq

3. sorry i don't know

4. 320 in sq

Step-by-step explanation & Answer:

Each question is a division, and they want to know which mixed number is equivalent. I can help.

Answer:

28 ÷ 20 =  1.4                          [tex]1\frac{2}{5} = \frac{7}{5} = 1.4[/tex]                                                

18 ÷ 4 = 4.5                             [tex]4\frac{1}{2}[/tex] [tex]= \frac{9}{2}[/tex] [tex]= 4.5[/tex]

9 ÷ 8 = 1.125                             [tex]1\frac{1}{8}[/tex] [tex]= \frac{9}{8}[/tex] [tex]= 1.125[/tex]

11 ÷ 6 = 1.8333...                     [tex]1\frac{5}{6}[/tex] [tex]= \frac{11}{6} = 1.8333...[/tex]

12 ÷ 17 = 0.70588235            [tex]\frac{12}{17} = 0.70588235[/tex]

Steps:

1. In order to find your equivalent fraction you need to divide your equations. The dividing goes for the fractions too.

2. If you don't know how to divide mixed numbers I can show you one of the fractions.

Example:

4[tex]\frac{1}{2}[/tex]

3. now after dividing your fraction and equation it should turn out as a decimal.

4. check if the equation has the same decimal if they do they're equivalent.

I hope this helped you have a great day

Answer:

1/26 or about 3.8%.

Step-by-step explanation:

There are 26 letters in the alphabet, and only one of them is the letter "K". Which means the probability would be 1/26. In percent form, that is about 3.8%.

Answer:

90 MPH

30 / (1/3) = 90

Answer:

90mph

Step-by-step explanation;

if an object travels 30 miles in the first part of an hour, and the speed is constant, then we can assume 30*3=90

in the first third, it went 30 mi, in the second it went 30mi, and in the last part it went 30 mi

30+30+30=90

or you could do 30* the denominator (in this case its 3), so 30*3=90

Sorry if this doesn't make sense, hope it helps though!

Answer:

168 degrees

Step-by-step explanation: first you would do (2x-3)+8x so you would have 10x-3 and that equals 180 degrees since its a straight angle. so you would do 10x-3=180 divide by 10, x-3=18 and add 3 so x=21  then since 2 is 8x you would multiply 8 by 21 which is 168.

Answer:

A

Step-by-step explanation:

The formula for circumfrence is C=pi x 2r or C= pi x r

In this case its C= 3.14 x 9 which is 28.26 rounded to 28.3

Answer:

Answer A is correct.

Step-by-step explanation:

Formula to find the circumference of a circle is :

C = π × d

Here,

d ⇒ diameter ⇒ 9m

First, let us find the circumference in terms of π.

C = π × d

   = π × 9

    = (9π)m

And now let us find the circumference to the nearest 10th.

Given that,

π = 3.14

Let us find now.

C = 9π m

   = 9 × 3.14 m

    = 28.26 m

    ≈ 28.3m

[tex]A.\ y-4=3(x-1)[/tex]

Step-by-step explanation:

[tex]A.\ y-4=3(x-1)\\\\B.\ 1-y=3(x-4)\\\\C.\ y^1-4=3(1=x1)\\\\D.\ 1-y1=3(4-x1)x^{2}[/tex]

[tex]A.\ y-4=3(x-1)\\\\A.\ 4-4=3(1-1)\\\\A.\ 0=3(0)\\\\A\ 0=0[/tex]

This statement is correct

Therefore, A is the correct answer.

Answer:

-1/3

Step-by-step explanation:

Answer:

-0.33

Step-by-step explanation:

The slope is -0.33 bc first, the line is going down so its negative. Second, use rise/run which is the Hight from each point / the length from each of the points. you can see that the rise is one, and the run is three so do 1/3 which equals -0.33

The answer is 571/1000

Step-by-step explanation:

Answer:

x = 7.4 ft.

Step-by-step explanation:

Find the area of the base (32.5ft^2) and divide the area by that to find the height (240.5/32.5= 7.4ft)

The height of the prism is 7.4 feet.

Volume of a three dimensional shape is the space occupied by the shape.

Given is a right trapezoidal prism.

Area of the prism = Base area × Height of the prism

Base is trapezoid.

Base area = [tex]\frac{1}{2}[/tex] (8 + 5) 5

                 = 32.5 feet²

Height of the prism = Length between the bases = x feet

So we have,

32.5 x = 240.5

x = 240.5 / 32.5

x = 7.4 feet

Hence the height of the prism is 7.4 feet.

Answer:

64[tex]\pi[/tex] in²

Step-by-step explanation:

I did not ever do a problem like this, however this is the beauty of math, you can easily reverse engineer it.

Remember,

A = [tex]\pi[/tex][tex]r^{2}[/tex]

And if we have 4 circles that means the area of one circle is 1/4th the total

So,

A=[tex]\frac{\pi r^{2} }{4}[/tex]

Assuming that 16 is the radius squared times 4 lets ignore that squared for now because when going backwards we would get rid of the squared last as that was the first step.

A= [tex]\frac{16\pi }{4}[/tex]=[tex]\frac{4\pi }{1}[/tex]=4[tex]\pi[/tex]

Now lets get it back to [tex]r^{2}[/tex] by square rooting the 4

A=[tex]\sqrt{4\pi }[/tex]=2[tex]\pi[/tex]

The radius of one small circle is 2. Therefore; the diameter would be 4 for each. This in mind we know that two small circles diameters make up the radius of the larger circle we will multiply it by two again.

This gives us a final radius of the bigger circle of 8

Therefore, the area of the bigger circle is 8²[tex]\pi[/tex] which simplifies to 64[tex]\pi[/tex]

And a final answer of

64[tex]\pi[/tex] in²

Answer:

-1/4

Step-by-step explanation:

Since there is a positive and negative sign next to each other it would automatically become a negative sign so then your equation should be 1/2-3/4 now you would need to find the common denominator since 2 can go into 4 2x the equation would be 2/4-3/4 now you would subtract that to get -1/4
