12/100= 0.12
0.12* 10 = 1.2
12 - 1.2 = 10.8

1.2*6 = 7.2

10.8 + 7.2 = 18

Lucy’s parents built a swimming pool in the backyard. Use 3.14 for π.

Neporo4naja [7]

Answer:

Distance around the pool = 162.8 feet

Area of the pool = 957 square feet

Step-by-step explanation:

Distance around the swimming pool = Perimeter of the pool

Perimeter of the pool which is a composite figure will be,

= Circumference of the semicircle + Sum of three sides of the pool

= πr + 2×(length of the pool) + width of the pool

= 3.14×(10) + 2×40 + 20

= 62.8 + 80 + 20

= 162.8 ft

Area of the pool = Area of the semicircle + Area of the rectangular pool

= $\frac{1}{2}(\pi)(r)^{2}+(\text{length}\times \text{Width})$

= $\frac{1}{2}(3.14)(10)^2+(40\times 20)$

= 157 + 800

= 957 square feet

Find the scale factor of a cube with volume 216 ft^3 to a cube with volume 1000 ft^3.

Bad White [126]

Answer:

Scale factor of cube to the smaller cube is 5 : 3.

Step-by-step explanation:

Ratio of the volumes of two cubes = $\frac{\text{volume of large prism}}{\text{Volume of small prism}}$

= $\frac{1000}{216}$

= $\frac{125}{27}$

Scale factor of these cubes = $\sqrt[3]{\text{ratio of the volumes of the cubes}}$

= $\sqrt[3]{\frac{\text{volume of large prism}}{\text{Volume of small prism}}}$

= $\sqrt[3]{\frac{125}{27} }$

= $\frac{5}{3}$

= 5 : 3

Therefore, scale factor of cube to the smaller cube is 5 : 3.

1.
5u - 2u = 3u (diff. between longest and shortest)
3u = 87cm
1u = 87cm ÷ 3 = 29cm
5u + 4u + 2u=11u
11u = 11 x 29cm = 319cm

Ans: 319cm

2.
9u = 1350
1u = 1350 ÷ 9 = 150
6u + 5u = 11u
11u = 11 x 150 = 1650

Ans: 1650
