Answer:

Step-by-step explanation:

the straight sides are just 4.5 *2 = 9 cm

the arcs are  2\pir * Ф/360

where Ф= 50 for this problem

and r = 8

the inner arc is  2\pi(3.5) *50/360 = 3.05432

the outer arc is 2\pi(8)*50/360 = 6.98131

The length of a rectangle is 1 foot more than twice the width the perimeter is 44 feet find the dimensions of the rectangle
Annette [7]

The length of rectangle is 15 feet and width is 7 feet.

Step-by-step explanation:

Given,

Width of rectangle = w

Length of rectangle = 2w+1

Perimeter = 44 feet

Perimeter = 2(Length+Width)

Perimeter=2(2w+1+w)\\44=2(3w+1)\\44=6w+2\\44-2=6w\\42=6w\\6w=42

Dividing both sides by 6

\frac{6w}{6}=\frac{42}{6}\\w=7

The width of rectangle is 7 feet.

Length of rectangle = 2(7)+1 = 14+1 = 15 feet

The length of rectangle is 15 feet and width is 7 feet.

Keywords: rectangle, perimeter

Sonja [21]

Answer:

The overall change is -$7.00.

Step-by-step explanation:

If a price goes down $4.25 than it is a negative integer. Same situation if a price goes down $2.75; it is still a negative integer. These two numbers can be expressed as -$4.25 and -$2.75. Finding the overall change causes for adding. Same signs add and keep different signs subtract. -4.25+-2.75=7.00. Therefore, the overall change in price for the two days is -$7.00.
