The perimeter of the rectangle below is 134 units. Find the length of side RS. Write your answer without variables
Eddi Din [679]

Answer:

RS = 30 units

Step-by-step explanation:

Given:

Length (PS) = 4y + 1

Width (PQ) = 3y + 3

Perimeter = 134 units

Required:

RS (width)

SOLUTION:

Perimeter of a rectangle = 2(length + width)

Plug in the values into the equation

134 = 2[(4y + 1) + (3y + 3)]

134 = 2[4y + 1 + 3y + 3]

134 = 2[7y + 4]

134 = 14y + 8

Subtract 8 from each side of the equation

134 - 8 = 14y

126 = 14y

Divide both sides by 14.

126/14 = 14y/14

9 = y

y = 9

✍️RS = Width (PQ) = 3y + 3

Plug in the value of y

RS = tex] 3(9) + 3 [/tex]

RS = tex] 27 + 3 [/tex]

RS = 30

According to data on the website for the Centers for Disease Control and Prevention (CDC), 35% of American adults were obese in
Serggg [28]

Answer: 2.2464 × 10^8

Step-by-step explanation:

Percentage of obese Americans in 2011 - 2012 = 35%

Percentage of Americans who are adult = 72%

United States population estimate = 312 million

Adult = age 20 and above

Number of adult Americans (age 20 and above) :

72% of the total united states estimated population

72% of 312,000,000

72/100 × 312,000,000

0.72 × 312,000,000

= 224,640,000

Hence, estimated Adult American population (age 20 and above) = 224,640,000

2.2464 × 10^8
