Answer:

8 : 1

Step-by-step explanation:

Given ratio of sides = a : b, then

ratio of area = a² : b²

ratio of volumes = a³ : b³

Given

ratio of areas = 384 : 96 = 4 : 1 ← in simplest form, then

ratio of sides = \sqrt{4} : \sqrt{1} = 2 : 1

Hence

ratio of volumes = 2³ : 1³ = 8 : 1

Courtney must earn at least $150 to pay for broken window. She earns $10 for every car she washes.
valkas [14]

Answer:

10c ≥ 150

At least 15 cars (or c ≥ 15)

Step-by-step explanation:

If she gets $10 for every car she washes a car then 10c is the rate of her gaining money and she needs at least (greater than or equal to) $150.

This equation can be used to express the situation:

10c ≥ 150

<em>To solve you divide the 10 from both sides of the inequality to get.</em>

c ≥ 15

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC b
iragen [17]

The student made the mistake in Step 2.

It should be m∠o + m∠p = 180 (Supplementary angles)

If this is corrected, then, since m∠m + m∠n + m∠o = 180 from Step 1,

we have,

m∠m + m∠n + m∠o = m∠o + m∠p which is Step 3.

Cancelling m∠o both sides, we get,

m∠m + m∠n = m∠p which is Step 4.

Answer:

28.3 square inches

Step-by-step explanation:

Use the area of a circle to determine its area:

A=\pi r^2\\\\A=\pi(3)^2\\\\A=9\pi\\\\A=9(3.14)\\\\A=28.26\\\\A\approx28.3

Therefore, the area of a circle with a radius of 3 inches is 28.3 square inches
