If your machine takes up 350sq. ft. and you are asked to scale down a drawing onto a 8" x 10" piece of paper what is your percen

Mnenie [13.5K]

Answer:

the scale is 630:1 = 0.16%

80inch^2 of 50400inch^2 however = 0.16%

Step-by-step explanation:

350ft^2 = 50400inches 8 x 10 = 80inches = 50400/80 = 630

50400/9 =5600 we distribute

5600/80 = 7

showing us that 7 x 9 = 63 where 63 x 80 = 5040 1/100th

1 = 630

7x9x 80 = 1/100 of 50400

0.01589 x 7x9x80x 7x9x80 = 80

Proves that every every 10000 the percentage goes down 0.00011%

Which value is equivalent to 3/11? OA A. 0.27 O B. 0.27 OC C. 3.6 OD. 3.

Sladkaya [172]

Answer:

0.27 repeating.

Step-by-step explanation:

So to solve this we just have to use division.

1 clearly doesnt go into 3 at least one time, so we can add a decimal point and add a 0 to make it 30.

11 goes into 30 2 times, so we have:

0.2

and 30-22=8

So we can add another 0 and make it 80.

Then 11 goes into 80 7 times. So we have:

0.27

and 80-77=3

So again, add the 0, we have 30.

11 goes into 30 2 times, so:

0.272

and 30-22=8

Add another 0 we get 80.

11 goes into 80 7 times.

So finally, we have:

0.2727.

This is a repeating decimal.

This can be shown as:

0.27

So this is your answer!

I was a bit confused with which one it was on your answer key, but knowing that it is 0.27 I am guessing you can chose!

Hope this helps!

Solve GHI. Round the answer to the nearest hundredth.

Sedaia [141]

Answer:

Part 1) $HI=15\ units$

Part 2)

Part 3) $< I=28.07\°$

The answer is the option A

Step-by-step explanation:

Part 1) Find the measure of side HI

Applying the Pythagoras Theorem

$GI^{2} =GH^{2}+HI^{2}$

substitute the values and solve for HI

$17^{2} =8^{2}+HI^{2}$

$HI^{2}=17^{2}-8^{2}$

$HI^{2}=225$

$HI=15\ units$

Part 2) Find the measure of angle G

In the right triangle GHI

$cos(G)=\frac{GH}{GI}$

substitute the values

$cos(G)=\frac{8}{17}$

$G=arccos(\frac{8}{17})=61.93\°$

Part 3) Find the measure of angle I

Remember that

The sum of the interior angles of a triangle must be equal to 180 degrees

substitute the values

$61.93\°+90\°+< I=180\°$

$< I=180\°-(61.93\°+90\°)=28.07\°$
