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

1 answer:

6 0

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.

Dan bought a new computer for $900. Each year, the value of the computer decreased by 25% of the previous year’s value. At this

lys-0071 [83]

Answer:

$120.14

Step-by-step explanation:

This question is an example of a compound percentage decrease.

To work this out you would first need to convert the percentage of 25 into a decimal. You can do this by dividing the percentage of 25 by 100, this gives you 0.25. This is because percentages are out of 100.

The next step is to minus 0.25 from 1, this gives you 0.75. This is because we are working out the percentage decrease.

The final step is to multiply the amount of 900 by 0.75 to the power of 7, this gives you $120.14.

1) Divide 25 by 100.

$25/100=0.25$

2) Minus 0.25 from 1.

$1-025=0.75$

3) Multiply 900 by 0.75 to the power of 7.

$900*0.75^7=120.14$

Maël mixes 15 milliliter (mL) of bleach with 3.75 liters (L) of water to make a sanitizing solution for a daycare. The amounts o

Yanka [14]

You have not provided the options, therefore, I cannot give you an exact answer.
However, I will try to help you with the concept.

First, we need to make all units the same in the problem. I will convert all units to ml.
We have:
amount of bleach = 15 ml
amount of water = 3.75 liters = 3.75 * 1000 = 3750 ml

Now, we will get the ratio between bleach and water:
$\frac{bleach}{water} = \frac{15}{3750} = \frac{1}{250}$

This ratio is fixed, therefore, to get the right choice:
1- make all units the same
2- for each option, divide the amount of bleach by the amount of water.
The correct choice would be the one giving you $\frac{1}{250}$

Hope this helps :)

A flower pot’s base has six sides that are all the same length. Each side measures x−6x-6 units. The base’s perimeter is 78 unit

NemiM [27]

Answer: The answer is x = 19.

Step-by-step explanation: Given that a flower pot has a base with six equal sides of measurement (x - 6) units. We are to find the value of the unknown quantity 'x' if the perimeter of the base is 78 units.

We know that the perimeter of a polygon is given by the sum of the lengths of all the sides of the polygon.

Since each side of the six-sided base is (x - 6) units, so its perimeter will be

$6\times(x-6)~\textup{units}.$

According to the question, we have

$6(x-6)=78\\\\\Rightarrow x-6=13\\\\\Rightarrow x=19.$

Thus, the value of 'x' is 19 units.
