One side of a rectangle is 10 feet shorter than twice another side. Find the length of the shorter side if we also know the peri

seropon [69]

Answer:

6 feet

Step-by-step explanation:

Let x represent the length of "another side." Then "one side" is ...

2x -10 . . . . . . 10 feet shorter than twice another side

The sum of these two side lengths is half the perimeter, so is ...

x + (2x -10) = 14 . . . . . two sides are half the perimeter

3x = 24 . . . . . . . . . . . . add 10, collect terms

x = 8 . . . . . . . . . . . . . . .divide by the coefficient of x

(2x -10) = 2·8 -10 = 6 . . . . find "one side"

We have found "one side" to be 6 feet long, and "another side" to be 8 feet long. The shorter side is 6 feet.

A man pays only $60 for an item which originally sells for $100. What percent of the original price does the man pay for the ite

Anni [7]

Answer: 40%. Alternatively, you can think about it this way. The item is 40% off. This means you'll pay 60.000% of the total cost (100% - 40% = 60.000%).

The City Housing Authority has received 50 applications from qualified applicants for eight low-income apartments. Three of the

OlgaM077 [116]

The probability that both specific qualified applicants will be among the eight selected is given by:
$P(2\ specified)=\frac{2C2\times 48C6}{50C8}=0.0229$
The probability that the two will get apartments on the North side is given by:
$P(North)=\frac{3C2\times5C0}{8C2}=0.107$
The probability that the two will get apartments on the South side is given by:
$P(South)=\frac{5C2\times3C0}{8C2}=0.357$
The events '2 apartments on North side' and '2 apartments on South side' are mutually exclusive. Therefore the probability the two specific qualified applicants will be on the same side of town is 0.107 + 0.357 = 0.464.
Finally, the probability that two specific qualified applicants will be selected for apartments on the same side of town is found from:
$0.0229\times0.464=0.01063$
