A scoop of ice cream is the shape of a whole perfect sphere sits in a right cone.

Andrei [34K]

Answer:

10 cm

Step-by-step explanation:

The volume of a sphere is given by the formula ...

V = 4/3πr³

The volume of a cone is given by the formula ...

V = 1/3πr²h

The ratio of the volume of the cone to that of the sphere is ...

Vcone/Vsphere = (1/3πr²h)/(4/3πr³) = h/(4r)

In order for the ratio to have a value of 1, we must have ...

h = 4r

The height of the cone must be 4×2.5 cm = 10 cm to fit all of the ice cream.

Find the measure of each angle in the isosceles trapezoid.

Scrat [10]

Answer:

Below in bold.

Step-by-step explanation:

m < C = m < D = 64 degrees

m <A + m < D = 180

m < A + 64 = 180

m<A = 180 - 64 = 116 degrees.

m < B = m< A = 116 degrees.

Solve for y: 2½y = ⅝ Answer in simplest form.

MrMuchimi

Step-by-step explanation:

$2 \frac{1}{2} y = \frac{5}{8}$

Convert Mixed number to improper fraction.

$2 \frac{1}{2} = \frac{5}{2}$

Equate

$\frac{5}{2} y = \frac{5}{8}$

Cross Multiply

$5y \times 8 = 2 \times 5 \\ 40y = 10$

Divide both sides of the equation by 40

$\frac{40y}{40} = \frac{10}{40}$

Simplify

$y = \frac{1}{4}$
