Answer:

<u>Option D : c =200t</u>

Step-by-step explanation:

The number of calories burned C varies directly with the time spent exercising T

∴  ∝ t

∴ c = a t

Where a is the constant of proportion

exercising for 4 hours he burns 800 calories

∴ c = 800 when t = 4

∴ 800 = 4 a

∴ a = 800/4 = 200

∴ c = 200 t

<u>The answer is option D : c =200t</u>

I need help with these 2 problems I cant figure out.
Alla [95]

I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.

2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)

Next, I add 20 on both sides.

2x + 90 + 3x = 200º

I combine like terms (2x and 3x)

5x + 90 = 200º

I subtract 90 from both sides.

5x = 110º

Divide 110 by 5 to get x.

x = 22

======

For problem two, I label all the angles I know.

49º + 80º + r = 180º

I add 80 and 49.

129º + r = 180º

I subtract 180 and 129 and get 51º, which is your angle for R.

For angle X, you know that angle R plus angle X equals half of a circle, which is 180º

We know from before that 129º is 180º without R, so X is 129º

I hope this helps! Let me know if I'm wrong!
