<h2><u>Answer:</u></h2>

<u>15 people</u> don't like either song.

<u />

<h2><u>Step-by-step explanation:</u></h2>
  • First, take 35 away from both preferences to work out the amount of people who ONLY LIKE 1 GENRE.

       FROCKS: 65 - 35 = 30 people

       MODERN: 55 - 35 = 20 people

  • This means that 30 people like frock, 20 people like modern and 35 like both; this means <u>85 people liked at least 1 of the 2 genres.</u>
  • Take this away from 100 to work out how many people liked NOTHING:

        100 - 85 = <u>15 people</u>

Heather sees that two stores have similar sales. Store A says that 5 balloons will cost her $6.00 and store B says that 13 ballo
MatroZZZ [7]

Answer:

Store A and it would cost $32.40 (answer choice A)

Step-by-step explanation:

Let's start by studying how much she would pay for a single balloon on each store:

In store A: (5 balloons for $6) then per each balloon: $6/5 = $1.2 per balloon.

In store BA: (13 balloons for $16.25) then per each balloon: $16.25/13 = $1.25 per balloon.

This shows us that the better price is in store A if she wants to pay as little as possible. Now, at that price, if she wants to buy 27 balloons, she will be paying (27 times $1.2): 27 * $1.2 = $32.40

A circle in the xy plane has a center at (3/4, 1/2)
Leokris [45]

Answer:

(x - 3/4)^2 + (y - 1/2)^2 = r^2

<em>Brainliest, please!</em>

Step-by-step explanation:

Equation of a circle: (x - h)^2 + (y - k)^2 = r^2

(x - 3/4)^2 + (y - 1/2)^2 = r^2

We do not have enough information to find the radius. Were you given another point that lies on the circle?
