Answer:
165cm³
Step-by-step explanation:
30% of 550cm³=30/100 *550cm³=3*55cm³=165cm³
91 / 7
7 fits within 9 only once, so the first number is 1
you have two left over
drop the one from 91 down, so you have to figure out how many times 7 goes into 21
it goes in 3 times
so the answer is 13

29 - 82
since 82 is bigger than 29, you will be getting a negative number.
if you did 82 - 29 it would be 53
but after you hit zero, it is 52 below zero, so the answer is -53
Answer:
Step-by-step explanation:
From the first set 20 corresponds to 1/6
for a fraction of 2/3 = 4/6
thus 4 * 1/6 = 4 * 20 = 80 calories
For 10 calories,
20 * 1/2 = 10 calories thus
1/6 * 1/2 = 1/12
For 90 calories,
10 * 9 = 90 calories thus,
1/12 * 9 = 9/12 = 3/4

Answer:
36.9°
Step-by-step explanation:
→ Identify the triangle required by seeing which side is not given
Hypotenuse is not given so we need to use Tan⁻¹ = Opposite / Adjacent
→ Substitute values in
Tan⁻¹ = ( 3 ÷ 4 )
→ Simplify
36.9°
