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>
Answer:
m = 2
Step-by-step explanation:
Plug 2 coordinates into the slope formula
(y2-y1)/(x2-x1)
For this I will choose the first and third coordinates:
15-7/5-1 = 2
The slope is 2
2x2+5x=12, 2x+5x=7x, 12+2=14, 7x/7=14/7, x=2
Answer:
7630
Step-by-step explanation:
We have that the distance of a comet from Earth is about 7.63*10³ .
This number is given in scientific notation.
We want to write this number in standard form.
Since we are multiplying by a power of 10, we move forward three times.
Therefore in standard form:
Answer:
80 Students are in the band class
Step-by-step explanation:
I did this mentally so sorry if it is bad
16 = 20%
+
16 = 20%
= 40% 32 students
40% +40% = 80%
32+ 32 = 64
80+20%
64+16
80 Students are in the band class
