Answer: 26 13/30 feet

Step-by-step explanation:

The hall is in the shape of a rectangle. The perimeter of a rectangle is:

= 2(length + width)

= 2l + 2w

Since perimeter = 71 2/3 ft and Width = 9 2/5 ft wide, the length will be calculated thus:

Perimeter = 2l + 2w

71⅔ = 2l + 2(9 2/5)

71 2/3 = 2l + (2 × 47/5)

71 2/3 = 2l + 94/5

71 2/3 = 2l + 18 4/5

Collect like terms

2l = 71 2/3 - 18 4/5

2l = 71 10/15 - 18 12/15

2l = 52 13/15

l = (52 13/15 ÷ 2)

l = 793/15 × 1/2

l = 793/30

l = 26 13/30

Therefore, the length is 26 13/30ft

Rochelle works part-time at the college museum, which pays her at a rate of $10 per hour. She also makes small bracelets that sh
katrin [286]
We know for our problem that Rachel makes $10 per hour. Sincex represent the number of hours that she works,  10x will be the total amount that she will make for working x hours. We also know that she sells bracelets for $5 each. Since y represents the number of of bracelets that she sells, 5y will be her total revenue for selling y bracelets. We also know that she needs to earn at least $200 a week to cover her expenses, so the sum of 10x and 5y must be equal or greater than 200:

10x+5 \geq 200

We can conclude that <span>the graphs that shows the inequality that represents this situation, with its solution region shaded is:</span>

Jay estimates that a basketball weights about .5 pounds. Shawna estimates that a basketball weights about.05. Whose estimate is
Natasha_Volkova [10]

Answer:

Jay's estimate is closer to the actual weight of the basketball

Step-by-step explanation:

The standard weight of an NBA basketball is 1.4 pounds.

Judging the accuracy of Jay's and Shawna's answer based on their percentage error when compared with the standard, we have that Jay's answer has a lower error as shown below

Error  = (Standard value - Estimated value)/ Standard Value ×100

Error in Jays answer = \frac{1.4 - 0.5}{1.4} × 100 = 64.28 %

Error in Shawna's answer = \frac{1.4 - 0.05}{1.4} × 100 = 96.42%

From this, It is obvious that Jay's answer has a lower percentage error when compared to the actual value.

A square playground has an area of 175 m2. What is the approximate length of each side of the playground? Round your answer to t
igomit [66]
We know that the area of a square = side &sup2;

Therefore, for a known area A, the side length is
side = &radic; (area)
= &radic; (175) 
= 13.2288  (to 4 places of decimals).
