the length of a rectangle is 2 inches more then twice its width. find the widtg of the rectangle if the perimeter is ar least 10
Lelu [443]

Answer:

width = 16 inch.

Step-by-step explanation:

Given,

let the width be x

so, length = 2 in. more than twice its width = 2 + 2x

perimeter = 2l + 2b

we know,

perimeter = 100 in

so, 2l + 2b = 100

after inserting the values we got,

→ 2(2+2x) + 2(x) = 100

→ 4 + 4x + 2x = 100

→ 4 + 6x = 100

→ 6x = 100 - 4 = 96

→ x = 96/6 = 16

therefore, width is x so width of rectangle is 16 inch.

Two geometric figures are similar figures if and only if there is a similarity transformation that maps one of the figures onto the other. Similar figures have the same shape but not necessarily the same size.

An employee earns $195 for 15 hours of work. Assuming he is paid by the hour, how much will the employee earn in 8 hours?
vampirchik [111]

Answer:

$104

Step-by-step explanation:

  1. First, find the employee’s hourly rate.  You can do this by dividing the total amount earned by the total hours worked. \frac{195}{15}=13
  2. Now that you know that the employee’s hourly rate is $13 per hour, you can multiply the hourly rate by the number of hours. 13*8=104
