Ilya [14]

In order to get the answer to this problem, first we have to find out how many pounds does one case of pancake mix have. We know that one box has 1.3 pounds of pancake mix. We also know that one case has 12 boxes. So first, we multiply 1.3 to 12. The answer we will get is 15.6. One case of pancake mix has a total of 15.6 pounds of pancake mix. Now we also know there are 7.5 cases that George bought. So in order to get the total pounds George bought, we multiply 15.6 to 7.5. So all in all, George bought 117 pounds of Pancake Mix.

Answer:

91.

Step-by-step explanation:

The least number will be a multiple of 7 while the number - 1 will be a multiple of 2,3 and 5.

2*3*5 = 30 but 31 is not a multiple of 7.

2*2*3*5 = 60 but 61 is not divisible by 7.

2*3*3*5 = 90 and 91 is divisible by 7.

A square outdoor patio with side length x feet is surrounded by a brick walkway that is 4 feet wide. What is the area of the wal

Masja [62]

Answer:

Area of walkway = 16(x+4) $ft^{2}$

Step-by-step explanation:

Length of the sides of the square outdoor = x feet

Area of the square outdoor = length x length

= x * x

= $x^{2}$ $ft^{2}$

The square outdoor is surrounded by 4 feet of walkway. So that,

length of the walkway = (x + 2(4))

= (x + 8)

Area of walkway with outdoor = (x + 8)*(x + 8)

= ( $x^{2}$ + 16x + 64) $ft^{2}$

Area of walkway = Area of walkway with outdoor - Area of the square outdoor

= ( $x^{2}$ + 16x + 64) - $x^{2}$

= 16x + 64

Area of walkway = 16(x+4) $ft^{2}$
