Answer:
8.55 inches tall
Step-by-step explanation:
equation: h = -0.75t +12. The slope is -0.75 because that's the rate of the candle burning, and the y intercept is 12 because that's how tall it is initially.
Now plug in 4.6 for t you get:
h = -0.75t + 12
h = -0.75(4.6) + 12
h = -3.45 +12
h = 8.55 inches tall

Answer:
64 -16π square units
Step-by-step explanation:
The area of the square is ...
A = (8 units)^2 = 64 units^2
The area of the circle is ...
A = πr^2 = π(4 units)^2 = 16π units^2
The shaded area is the difference:
shaded area = (64 -16π) units^2.
Answer:
The measure of AC is 4 and 46.
Step-by-step explanation:
Answer: The answer is (a) 3 × x = y and (b) x + x + x = y.
Step-by-step explanation: Let 'x' and 'y' denote the number of hours that Tina practised last month and this month respectively.
Then, according to the given information, we have
x = 15 and y = 45.
We can write the relation between 'x' and 'y' in two forms as follows -
(a) Multiplication form : 3 × 5 = 15 implies 3 × x = y.
(b) Addition form : 15 +15 +15 = 45 implies x + x + x = y.
Thus, the answers are (3 × x = y) and (x + x + x = y).
Answer:
The answer should be A.
