Answers

Answer 1

Answer:

Answer:

1.8g/cm^3

Step-by-step explanation:

Density = mass/volume

=> Density = 45/25

=> Density = 9/5

=> Density = 1.8 g/cm^3

A party hat has a volume of 75 cubic inches . If the radius is 5 inches , what is the height of the party hat?

Answers

The height of the party hat is 2.63 inches.

Given that,

A party hat has a volume of 75 cubic inches.

If the radius is 5 inches,

We have to determine,

What is the height of the party hat?

According to the question,

A party hat has a volume of 75 cubic inches.

If the radius is 5 inches,

The volume of the cone is determined by the formula,

$\rm v = \pi r^2(h)/(3)$

Then,

The height of the party hat is,

$\rm v = \pi r^2(h)/(3)\n\n75 = \pi* (5)^2 * (h)/(3)\n\n75 = 25 * (22)/(7) * (h)/(3)\n\n75 = 25 * 1.14 * h\n\n75 = 28.5 * h\n\nh = (75)/(28.5)\n\nh =2.63$

Hence, The height of the party hat is 2.63 inches.

Answer:

About 2.86 inches

Step-by-step explanation:

The formula for the volume of a cone is $\pi r^2(h)/(3)$ . Plugging the known numbers into this formula, you get:

$75=\pi \cdot 5^2\cdot (h)/(3)$

$(h)/(3)\approx 0.955$

$h\approx 2.86$ inches. Hope this helps!

Probability of rolling factors of 24

Answers

Factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24 and rolling a 6-sided die you can get 1, 2, 3, 4, 5, 6 so 5 is the only thing you can roll that isn't a factor of 24 so

5/6 is the probability
