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 triangle in the drawing is semi equilateral. Therefore a=√(14^2-7^2)=12.12 cm
The base of a regular pyramid consists of 6 equilateral triangles. The area of each triangle is: (14*12.12)/2 = 84.87 cm^2
The base: 6*84.87=509.22 cm^2

i AM PRETTY SURE ITS D
Answer: I think the answer is 4x^2/(4x+3) (x-1)
Alright, lets get started.
I hope, the dimensions of rectange are asked in this question.
Suppose the width of rectangle = x in
Given that length of the rectangle is 3 in longer than the width.
It means length of the rectangle = (x+3) in
Now, the area of the rectangle = lenght * width
area of the rectangle = 
area of the rectangle =
The area of a rectangle is 70 in square (given in question)
Equalling both areas

Subtracting 70 in both sides


Factoring

It will give two values of x
x = -10 (which is not possible because length could not be negative)
x = 7
Means width 
length 
Means the dimensions of rectangle are 7 in and 10 in. : Answer
Hope it will help :)
