Let's put this into only hours to make it simple.
Multiply 7 and 4 by 24.
7x24 = 168
4x24 = 96
Now that we have the total hours of days, add the extra hours to the total hours of days,
168 + 4 = 172
96 + 7 = 103
Subtract the two totals.
172-103 = 69.
There are 69 total hours left. Now we need to convert that into days and hours, so divide 69 by 24.
69/24 = 2.875, or 2 days.
We have 2 days, which is 48 hours.
Subtract 48 from 69.
69 - 48 = 21. We have 21 hours.
Our difference is 2 days and 21 hours. I hope this helps!

Answer:

A. you need 2 1/2 ounces

B. you need 73,9 milliliters

Step-by-step explanation:

We have the ratio 1/2 ounces per gallon

And the mop bucket holds 5 gallons

Then we need to multiply 1/2*5

we got 2 1/2 ounces of desifectant per 5 gallons

1 ounces equal 29,57 milliliters

if we have 2 1/2 ounces then we multiply 2,5 *29,57

the answer is 73,9 milliliters

If a₁ = 4 and an = 5an-1 then find the value of a5.

igor_vitrenko [27]

The value of $a_{5}$ is 2500, when $a_{1}=4$ and $5a_{n-1}$ .

Given that, $a_{1}=4$ and $5a_{n-1}$ .

We need to find the value of $a_{5}$ .

<h3>What is an arithmetic sequence?</h3>

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

Now, to find the value of $a_{5}$ :

$a_{2} =5a_{2-1}=5a_{1}=5 \times4=20$

$a_{3} =5a_{3-1}=5a_{2}=5 \times20=100$

$a_{4} =5a_{4-1}=5a_{3}=5 \times100=500$

$a_{5} =5a_{5-1}=5a_{4}=5 \times500=2500$

Therefore, the value of $a_{5}$ is 2500.

Answer:

LQ = 54

Median = 69

UQ = 94

Step-by-step explanation:

This list is already sorted for you, so you don't need to worry about that, otherwise you would need to sort the numbers in ascending order. To find the median, we do $\frac{n+1}{2}$ , where n is the amount of numbers. This gives us 4, so the median is at position 4, so the median is 69. The lower quartile is simply $\frac{n+1}{4}$ , so 2, so the lower quartile is 54. The upper quartile is $\frac{n+1}{2} X 3$ , so 6, so the upper quartile is 94.
