There are 88 seats in a theater. The seating in the theater is split into 4 identical sections. Each section has 14 red seats and some blue seats.

a. Create an equation to represent this situation.

b. How many blue seats are in the theater?

c. How many red seats are in the theater?

Answers

If there's 14 red seats in each section, the total amount of red seats will be 14 times the 4 sections, which equals 56. We just subtract 56 from 88, which is equal to 32.

An equation for this would look like:

x+56=88

so:

a. x+56=88

b. 32 blue seats

c. 56 red seats

Answer:

a- (88/4) / 14 = Blue seats or red seats? maybe...

b- 56

c-56

triangle abc and dgf are similar the lengths of two corresponding sides are 1.4 m and 56 cm what is the ratio of the perimeters of these triangles?

Answers

The answer would be 1.8
The answer is 5/2 in fraction form or 2.5 in decimal form.

1.4 meters is equal to 140 centimeters. We can find the ratio with just these two side lengths because we know that the shapes are similar, so the other corresponding sides will also have the same ratio.

Then, we can take 140 and divide it by 56 which, simplified, gives us the fraction 5/2. Because of the Fundamental Theorem of Similarity, you keep the fraction the way it is. (If you are finding the ratio of areas or surface areas, you square the fraction, and if you are finding the ratio of the volumes you cube it.)

Divide the 2 cups of sugar by 1.5

or

Take the 2 cups of sugar and divide it by 3, then multiply that number by 2

Rounding to the nearest hundredth, each batch uses about 1.33 cups of sugar.

What is division?

Math operations include division as one of its types. This technique involves splitting the phrases or numbers into the same amount of components.

To find out how much sugar is used for each batch, we need to divide the total amount of sugar used for 1.5 batches by 1.5.

If 1.5 batches use 2 cups of sugar, then 1 batch will use:

2 cups ÷ 1.5 = 1.333... cups

Rounding to the nearest hundredth, we can say that each batch uses about 1.33 cups of sugar.
