Step-by-step explanation:

Although it does not look like the picture.
From the picture ∠F ≅ ∠Y...
We must stick to the correct writing:
Δ → Δ
C → Y
H → W
F → S

ΔMLK and ΔYWZ are not similar because they have different angles (different shape).
Each candle in the set is a different size.
The smallest candle has a radius of 0.5 inches and a height of 3 inches.
The other two candles are scaled versions of the smallest, with scale factors of 2 and 3.
How much wax is needed to create one set of candles?
in cubic inches
Answer
pi 0.5^2 *3 = 0.75pi is the volume of the first candle.
The second volume is 8 * 0.75pi = 6pi.
And the last volume is 27 * 0.75 pi = 20.25 pi So in total we just take the sum and that is 27pi
Answer:
x = 1, y = 7
Step-by-step explanation:
If y = -3x - 4, then
6x -3x -4 = 1
3x - 4 =-1
3x = 3
x = 1
If x = 1, then
y = -3*1 -4 = -3 -4 = -7
No it is not. that is a right scalene triangle. Acute triangle has three angles less than 90.
The volume is 2304
the surface area is 1120
