A. Divide both sides by 4
You want to get the value of x not 4x so in order to do that u can have divide both sides by 4 to get x alone on one side.
Step-by-step explanation:
The number of way to select 2 employees from 40 is 40C2.
The number of way to select 2 employees from 22 is 22C2.
So the probability of the two employees having single-vision correction is just the number of ways to select the 22 employees (22C2) divided by the total number of ways to select 2 employees (40C2).
22C2 / 40C2 = 77/260
We can use the same technique for the bifocal employees.
18C2 / 40C2 = 51/260
To make the problem easier, I’m going to convert these to improper fractions.
A woman is 36/7 inches taller and she’s 463/7 inches tall. Her daughter is (463/7) - (36/7) inches tall. 463-36 is 427. She is 427/7 inches tall or 61 inches tall.
The length of the window is 9 ft and the width of the window is 4 ft.
Answer:
RQ = 10
Step-by-step explanation:
When two triangles are similar, the ratio of their corresponding sides are equal;
Thus, we have it that;
QP/RQ = BC/AB
12/RQ = 36/30
RQ = 12 * 30/36 = 10
