Answer:

1: 24 girls

2: 640

3: 300

4: 3/10

5: 42

Step-by-step explanation:

1: 2/5 × 40

80÷ 5

16

girls = 40- 16

= 24

2: 1/3 × 960

960 ÷3

= 320

Left = 960 - 320

= 640

3: 3/8 × 480

1440 ÷ 8

= 180.

Left = 480 - 180

= 300

4: 2/5 × 3/4

= 6/20

= 3/10

5: 2/5 × x = 18

2x = 28 × 5

2x = 140

x = 70

70 - 28

= 42

A cone has a height 25 ft and a radius of 7 ft. Is a reasonable that the volume of this cone is 100 ft3? Why or why not?​
Nostrana [21]

Answer:

No

Step-by-step explanation:

the radius squared is 49 times π, which is roughly 3 means the area of the base is roughly 150 ft².

This means that one third of the height cannot be more than 100 / 150 = 2/3 of a foot. That makes the height about 2 ft, much less than the reported 25 ft.
