Svetllana [295]

Answer: 7/18

Step-by-step explanation:

Number of customers at Eva's boutique = 90

Number of customers who wore a size extra-large = 35

The probability that a randomly selected customer wore a size extra-large will be:

= Number of customers who wore a size extra-large / Number of customers at Eva's boutique

= 35 / 90

= 7/18

Therefore, the probability that a randomly selected customer wore a size extra large is 7/18.

The length of each side of an equilateral triangle is increased by 6 inches, so the perimeter is now 60 inches. What was the ori
Nimfa-mama [501]

Answer:

14 inches

Step-by-step explanation:

Using this information, we can form an equation.

Since there are 3 sides in a triangle, and each side increased by 6, that means that the perimeter increased by 18 inches. Down below, I did 3x because there are 3 sides in a triangle.

(This is the equation you'd want to do to get the answer)

3x + 3 * 6 = 60

Simplify:

3x + 18 = 60

Same to both sides

3x = 42

Isolate x:

x = 14

The formula for the circumference of a circle is C = 2r. What is one-fourth of the circumference of a circle that measures 12 ce
Harman [31]

The formula of a circumference is:

C=2\pi r

r - radius

or

C=d\pi

d - diameter

We have d = 12cm. Substitute:

C=12\pi\ cm

One-fourth of the circumference:

\dfrac{1}{4}C=\dfrac{1}{4}\cdot12\pi=3\pi\ cm\approx3\cdot3.14=9.42\ cm

<h3>Answer:  9.42 cm.</h3>
