Answer:
V = 166.4
Step-by-step explanation:
The ratio of lengths of similar figures is the scale factor.
The ratio of the surface areas of similar figures is the square of the scale factor.
The ratio of the volumes of similar figures is the cube of the scale factor.
We don't know the scale factor of the figures, but we know the ratio of the surface areas is 200/135.
That is the square of the scale factor.
Let k = scale factor.
k² = 200/135 = 40/27
The ratio of the volumes is
k³ = [√(k²)]³
k³ = [√(40/27)]³ = 1.80320
V = 300/1.80320
V = 166.4
Answer:
1 mile = 5280 feet
Step-by-step explanation:
To convert a distance of 12,000 feet to miles, we use this ratio:
1 mile = 5280 feet
? = 12,000 feet
Cross multiplying gives;
× 1 mile = 2.272727273 miles.
Answer:
B. X = 2
Step-by-step explanation:
2(0)+7 = 7 --> 7<9 so no
* 2(2)+7 = 11 --> 9<11<15 so yes *
2(4)+7 = 15 --> 15 = 15 so no
2(6)+7 = 19 --> 19>15 so no
Answer:
10/3 or 3 1/3
Step-by-step explanation:
4/3 ÷ 2/5 is the same as 4/3 × 5/2, which equals 20/6 or 10/3 simplified
