A lifeguard fills a pool with water at a constant rate. After 1/2 hour, 1/3 of the pool is filled.
At this rate, what fraction of the pool is filled per hour?

Answers

Answer 1

Answer: 2/3 of an hour.

Step-by-step explanation: The constant rate of the lifeguard filling the pool is 1/3 of the pool every 1/2 hour.  If she fills it for an hour, she'll get 2/3 of the pool filled.  Therefore, it'll take the lifeguard 1 hour to fill the pool 2/3 of the way.

Hope this helps! :)

A store sells grass seed in small bags and large bags. The small bags have 7 pounds of seed for $27.93 and the large bags have 20 pounds of seed for $66.98. Which type of bag is the better buy? Explain your reasoning.

Answers

Answer:

The 20 pound bag is a better by for only $66.98

Step-by-step explanation:

The large bag is better because the small bag is $27.93 for 7 pounds 7x3=21,so 3x27.93=83.79 is $16.81 more than the cost for the large bag

  (b)  2 32/48

Step-by-step explanation:

You want the value of the expression 8 4/8 -5 5/6.

Subtraction

The difference of the mixed numbers can be found as the sum of the differences of the integer parts and fractional parts.

  (8 4/8) -(5 5/6) = (8 -5) +(4/8 -5/6)

  = 3 + ((24 -40)/48) = 3 - 16/48

  = 2 +(48/48 -16/48) . . . . . . . rewrite 3 to give a positive fraction part

  = 2 32/48 . . . . matches the 2nd choice

Step-by-step explanation:

256 ft² wood will be needed for 4 props.

What is Surface Area?

The area is the space occupied by a two-dimensional flat surface. It is expressed in square units. The surface area of a three-dimensional object is the area occupied by its outer surface.

According to the figure,

The lengths are

= (5ft +8ft +7ft +2ft +3ft +5ft) x 2 x 4

= 32 x 2 x 4

= 256 ft²

Thus, 256 ft² wood will be needed for 4 props.

Susan has two dogs named Murphy and Fido. She feeds each of them the same type of dog food. Murphy eats 2/3 of a can of dog food each day. Fido eats 1/2 of a can of dog food each day. Each can of dog food costs $1.75. The pet store is offering a sale that allows customers to buy one can of food and get one free. Susan wants to buy a 60-day supply of dog food during the sale. To the nearest cent, what would be the cost of Susan's dog food purchase before tax?

Answers

Answer:

  $61.25

Step-by-step explanation:

The quantity for a 60-day supply is 60 times the 1-day usage. The BOGO offer means the sale price is effectively half the usual price.

__

One day supply: 2/3 can + 1/2 can = (4/6 +3/6) = 7/6 can

60-day supply: 60 × 7/6 can = 70 cans

Susan will be paying for 70/2 = 35 cans of dog food. (She will get 35 cans free.) So, her cost will be ...

  35 × $1.75 = $61.25

The cost of Susan's dog food purchase would be $61.25 before tax.

Clarissa is making punch for a party. She mixes 64 fluid ounces of orange juice, 64 fluid ounces of pineapple juice, and 36 fluid ounces of apple juice.

Let p represent the total amount of punch that Clarissa mixes.

Which equations could be used to find the value of p?

Select each correct answer.


A.64 + 64 + 36 = p

B.64 × 2 + 36 = p

C.64 × 64 × 36 = p

D.64×2−36=p

E.64+64−36=p

Answers

Answer: A and B.

Step-by-step explanation: The first option works because Clarissa is adding 64 fluid ounces of both orange and pineapple juice and 36 fluid ounces of apple juice which makes it an addition problem.  Option B works as well because it is similar to option A, only it shortens the problem by multiplying 64 twice, because 64 pops up twice.  Options C, D, and E don't work because it doesn't include taking away any juice or multiplying it in immense amounts, so that's why those are wrong.

Comment on the problem wording

Please be aware that the problem statement tells you only that he eats 2 granola bars each day. It does not tell you the relationship between Donovan's eating and Donvan's spending. The question asks about his spending, so there is insufficient information unless we make the assumption they are directly related.
