Answer:
112
Step-by-step explanation:
The volume is 448 
You are asked to dilate it to a scale factor of 1/4
All you are doing is multiplying: 448/1 × 1/4
Answer:
28 + 0.15x = 49.30
0.15x = 49.30 - 28
0.15x = 21.3
divide both sides by 0.15
x = 21.3/0.15
x = 142
Answer:
the hight is 3
Step-by-step explanation:
Answer:
- angle at A: 51°
- base angles: 64.5°
Step-by-step explanation:
The measure of the inscribed angle BAC is half the measure of the intercepted arc BC, so is 102°/2 = 51°.
The base angles at B and C are the complement of half this value, or ...
90° -(51°/2) = 64.5°
The angle measures in the triangle are ...
∠A = 51°
∠B = ∠C = 64.5°
Answer:
These are similar. The scale factor is 1.5 going from ABC to DEF.
Step-by-step explanation:
What I did was divide the side lengths of DEF by the corresponding side on ABC.
12/8 = 1.5
9/6 = 1.5
15/10 = 1.5
Since the scale factor is the same on all three sides, these two figures are similar.
