Answer:
A) 75 levels
B) Level 35
Step-by-step explanation:
A) 37 - (10 - 3) = 37 - 7 = 30
= 
2x = 150
x = 75
B) Gym = 37 + 3 = 40
12
% = 12.5% = 0.125
40 x 0.125 = 5
40 - 5 = 35
Answer:

Step-by-step explanation:
Let x be the number of minutes she can continue, since she's already 20 feet below the ocean surface and is diving at the rate of 20 ft/minute, her depth with respect to x would be
20 + 20x
But she doesn't want to reach more than 100 feet below the surface

Answer:
c = 12
Step-by-step explanation:
the ratio of sides in a 30-60-90° triangle, respectively, is 1:
: 2
if side opposite 30° is 6 then hypotenuse equals 12
25% of 64 is equal to 1/4 of 64. Therefore to get 25% we divide 64 by 4 to get 16.
ANSWER:
16
This can be solved by similar triangles, which means you can cross multiply and divide. 78/195=x/10. 78(10)=780 and divide 780 by 195, you'll get the answer is 4. This means Sarah is 4 ft tall.
