Answer:
A. Subtraction Property of Equality
Step-by-step explanation:
3x + 4 = 10
Subtract 4 from both sides ---->Subtraction Property of Equality
3x + 4 - 4 = 10 - 4
3x = 6
So
If 3x + 4 = 10, then 3x = 6
Answer
A. Subtraction Property of Equality
Answer: 1/6
Step-by-step explanation:
just simplify 2/12 to 1/6
2/12 both divided by 2
Answer:
142.1π in³
Step-by-step explanation:
Given that:
The radius (r) = 7 in
The slant height (y) = 25 in
Then the height (x) can be determined by using the Pythagoras rule:
y² = x² + r²
25² = x² + 7²
125 = x² + 49
125 - 49 = x²
x² = 76
x = √76
x = 8.7
The formula for the volume of a cone is;
= 1/3 πr²h
where;
height(h) is calculated as "x" from above = 8.7
Then;
= 1/3 × π × (7 in)² × 8.7 in
= 142.1π in³

Answer: 142°15'
Explanation:
Supplementary angles are angles that add up to make a straight angle (
).
Therefore, we must find the angle ∠B such that
∠A + ∠B = 180° (1)
We know that ∠A = 37°45', so we can re-arrange equation (1) to find the magnitude of ∠B:
∠B = 180° - ∠A = 180° - 37°45' = 142°15'
So, the correct answer is
142°15'
