The length of a rectangle is increased by 10 percent the width of a rectangle is increased by 5 find the percentage increased in
aalyn [17]

Answer: The percentage increase in perimeter is 7%.

Step-by-step explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length + width)

The original length of the rectangle is 20 and the original width is 30. The original perimeter of the rectangle would be

Perimeter = 2(20 + 30) = 100

The length of the rectangle is increased by 10 percent. It means that the new length would be

20 + (0.1 × 20) = 22

The width of the rectangle is increased by 5 percent. It means that the new width would be

30 + (0.05 × 30) = 31.5

The new perimeter of the rectangle would be

Perimeter = 2(22 + 31.5) = 107

The increase in perimeter is

107 - 100 = 7

The percentage increase in perimeter is

7/100 × 100 = 7%

Solve for the missing variable<br> (5, 4) &amp; (2, c) slope is equal to 1/2<br> Please answer fast
Aleksandr-060686 [28]

Answer:

c = \frac{5}{2}

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to \frac{1}{2}

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (2, c)

m = \frac{c-4}{2-5} = \frac{c-4}{-3} , then

\frac{c-4}{-3} = \frac{1}{2} ( cross- multiply )

2(c - 4) = - 3

2c - 8 = - 3 ( add 8 to both sides )

2c = 5 ( divide both sides by 2 )

c = \frac{5}{2}
