Determine whether these two ratios make a proportion;3/8, 24/64 True or False

Mathematics

Yes, we claim that the two ratios are proportional.

<h3>Proportion</h3>

Proportion is an equality between two ratios. These ratios are made up of two real integers. In a proportion, when there is an equality, both ratios have to be equivalent to the other. Equivalent ratio is when both division results are equal.

— To find out if the equality between these two given ratios is true, let's just: divide the numerator by the denominator.

3/8 = 3 ÷ 8 = <u>0,375</u>

24/64 = 24 ÷ 64 = <u>0,375</u>

Therefore, we see that the results of these ratios are the same. So these two ratios are proportional. 3/8 = 24/64

3^x=1/9<br><br> What does x equal?
Nastasia [14]

Answer: The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!

What is the upper quartile, Q3, of the following data set? 54, 53, 46, 60, 62, 70, 43, 67, 48, 65, 55, 38, 52, 56, 41
scZoUnD [109]
The original data set is 
{<span>54, 53, 46, 60, 62, 70, 43, 67, 48, 65, 55, 38, 52, 56, 41}

Sort the data values from smallest to largest to get
</span><span>{38, 41, 43, 46, 48, 52, 53, 54, 55, 56, 60, 62, 65, 67, 70} 
</span>
Now find the middle most value. This is the value in the 8th slot. The first 7 values are below the median. The 8th value is the median itself. The next 7 values are above the median. 

The value in the 8th slot is 54, so this is the median

Divide the sorted data set into two lists. I'll call them L and U 
L = {<span>38, 41, 43, 46, 48, 52, 53}
U = {</span><span>55, 56, 60, 62, 65, 67, 70}
they each have 7 items. The list L is the lower half of the sorted data and U is the upper half. The split happens at the original median (54).

Q3 will be equal to the median of the list U
The median of U = </span>{<span>55, 56, 60, 62, 65, 67, 70} is 62 since it's the middle most value. 

Therefore, Q3 = 62

Answer: 62</span>

Divide 82 in the ratio 1:3<br><br> will give brainliest to whoever answers first
Hatshy [7]

Answer:

20.5 : 61.5

Step-by-step explanation:

1:3

1 + 3 = 4

82 ÷ 4 = 20.5

ratio of 1:3

1 × 20.5 = 20.5

3 × 20.5 = 61.5

20.5 : 61.5

A loan officer makes $15 per hour working 2,000 hours each year. She also gets a fee of $35 for each loan she processes. If she
Afina-wow [57]

Answer:

$61,500

Step-by-step explanation:

For this problem, we will simply take her hourly wage and multiply that by the hours she worked and take her additional earnings for each loan processed and multiply that by the number of loans she processed.

Consider her hourly wage of $15 per hour. If she worked 2000 hours, then we can say she got paid ($15 * 2000) = $30000 for her work that year.

Consider her processing fee of $35 per loan processed. If she processed 900 loans, then we can say she got paid ($35 * 900) = $31500 for her processed loans that year.

Then, to find her yearly total earnings, we simply add those two values. $30000 + $31500 = $61500.

Thus the loan officer made $61500 that year.

Cheers.
