I pretty sure the answer is 3.2 hours. I'm not completely sure though....
Answer:
c = 21
Step-by-step explanation:
<u>**I assume that side WX in my diagram (attached as an image below) is the value of C that we're looking for. ALSO, the sizes and lengths of the parallelograms are NOT to scale.**</u>
If two parallelograms are similar, that means the lengths of the corresponding sides have EQUAL ratios.
PL corresponds with WZ. To get from 15 to 45, you would multiply 15 by 3, so the ratio of the legnths of the corresponding sides between these two parallelograms is 1:3.
With that in mind, we can apply this ratio to find WX.
We know that AP has a length of 7, so we will multiply that by 3, getting a value of 21, and 7:21 ratio is the same as 1:3.
c = 21

To get the area of the half circle, do π r².
Let's use 3.14 as pi.
First square 2 to get 4 then multiply it by 3.14 to get 12.56. Since this is a half circle we have to divide it by 2 for the area: 6.28.
Then for the triangle multiply 6 times 2 (12) then divide it by 2 to get 6. Then add the two together to get 12.28 then round to the nearest tenth to get a final answer of 12.3 m². Hope this helps!
Answer: y = -4x/3 + 4
Step-by-step explanation:
Assuming you want to solve for y:
4x = -3y + 12
-4x/3 = y - 4
y = -4x/3 + 4
