An animal shelter wants their ratio of dogs to cats to be 3:2. If the animal shelter has 78 dogs, how many cats should they have

OleMash [197]

The simplest way to do this is to set up equivalent fractions. So, you'd do:

$\frac{3}{2}$ = $\frac{78}{x}$ and then solve for x.

x=52

Anna71 [15]

Answer:

T ≥ -2

Step-by-step explanation:

Given

Temperature = 2° below 0°

Required

Represent as an inequality

First, we need to calculate the temperature in the morning.

2° below 0 means.

Temperature = 0° - 2°

Temperature = -2°

Next, we determine the temperature at any time.

The question says the temperature continues to rise during the day.

Represent this with T

This means T will be greater than -2°

However, we need to consider where the temperature started from.

In other words, T = -2

Combine T = -2 and T = -2 together, we have:.

T ≥ -2

Hence, the inequality that represents the scenario is T ≥ -2

Which best explains the formula? the central angle measure of the sector divided by the total angle measure of a circle multipli

DIA [1.3K]

The sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.

<h3>Area of a sector</h3>

The coloured portion of the circle is known as a sector. The formula for calculating the area of a sector is given as:

Area of a sector = θ/360 * πr²

where

θ is the central angle

πr² represents the area of a circle.

Therefore the best statement that explains the formula is expressed as the central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.
