Harold walks 3/4 mile in each 5/6 hour. Calculate Harold's unit rate. Explain how you found your answer.

Answers

To solve this problem, you must apply the proccedure shown below:

1. The problem gives the following information: Harold walks 3/4 miles in each 5/6 hours. Therefore, you have to divide 3/4 miles by 5/6 hours, as below:

unit rate=(3/4)(5/6)
unit rate=(3x6)(4x5)
unit rate=18/20

3. When you simplify, you obtain:

unit rate=9/10

4. Therefore, as you can see, the answer is: Harold's unit rate is 9/10.

When the perimeter of a rectangle is 68ft. and the ratio of it's length to it's width is9:8. What are the dimensions of the rectangle and how do you come about the answer?

Answers

rectangle's perimeter formula is p=2(length+width)
2(9x+8x)=68
17x=34
x=2
length is 9(2)=18 feet
width is 8(2)=16feet

Answer:

length is 9(2)=18 feet

width is 8(2)=16 feet

Step-by-step explanation:

rectangular perimeter formula is length plus width

2 ( 9x + x ) = 68

17x = 34

x = 2

Harper has $15.00 to spend at the grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers that costs $3.50. Write and solve an inequality that models this situation and could be used to determine the maximum number of bags of fruit, b, Harper can buy.

Answers

Answer:

4.75x + 3.75y ≤ 15 inequality models the given situation.

Harper can buy at maximum 3 bags of fruits.

Step-by-step explanation:

Given : Harper has $15.00 to spend at the grocery store. She is going to buy bags of fruit that cost $4.75 each and one box of crackers that costs $3.50.

We have to write and solve an inequality that models this situation and could be used to determine the maximum number of bags of fruit that Harper can buy.

Let Harper buys 'x' bags of fruit

and 'y' box of crackers

Given : cost of one bags of fruits is $ 4.75

so the cost of x bags of fruits is 4.75x

Given : cost of one box of cracker is $ 3.50

so the cost of y box of crackers is 3.75y

also, Harper has $15.00 to spend at the grocery store

So the maximum amount he can spend is $15

So inequality become,

4.75x + 3.75y ≤ 15

So the maximum number of bags of fruit Harper can buy.

is when he buys no box of cracker.

Put y = 0 in above inequality , we have,

4.75x + 3.75(0) ≤ 15

4.75x ≤ 15

Divide both side by 4.75

We have , x = 3.158 ≈ 3

So , Harper can buy at maximum 3 bags of fruits.

since harper has only %15 that is the most she can spend, therefore we would have 15> or = 4.75b+3.5c. the best way to solve this would be to divide 15 by 4.75, then round down to the nearest whole number. if you do this, you get 3 bags of fruit.
