The better deal is the 21-ounce one because its unit rate equals less than the 17-ounce one
Answer:
A pair of inverse operations is defined as two operations that will be performed on a number or. variable, that always results in the original number or variable. Another way to think of this is. that the two inverse operations “undo” each other.
Step-by-step explanation:
for example addition and subtraction are and divison and multiplication are, because they inverse each other.
Answer:
91%
Step-by-step explanation:
The first step is to calculate the increase
= 1635-858
= 777
Therefore the percent increase can be calculated as follows
= 777/858 × 100
= 0.905× 100
= 90.5 %
= 91%
Hence the percentage increase is 91%
Therefore, the measures of the angles in triangle ABC is as follows:
- m∠A 73.7°, m∠B = 16.3°, m∠C = 90°
<h3>How to find angles of right triangle?</h3>
The measure of the angles in the right triangle can be found as follows:
Using trigonometric ratios,
sin ∅ = opposite / hypotenuse
sin ∅ = 7 / 25
∅ = sin ⁻¹ 0.28
∅ = 16.2602047083
∅ = 16.3°
Hence,
m∠B = 16.3°
m∠C = 90°
m∠A = 180 - 90 - 16.3 = 73.7°
