7 as a percentage of 20

Mathematics

To find 7 as a percentage of 20, all you need to do is divide 7 by 20.

7 ÷ 20 = 0.35

And then, all we need to do is convert the resulting decimal into a percentage. We can do this by either multiplying the result by 100, or (my personal shortcut) just shifting the decimal point over two places to the left.

0.35 = 35%

Which is our answer.
7 is 35% of 20.
Hope that helped! =)

7 as a percentage of 20 just means what percentage of 20 is 7. To do this, we must divide 7 by 20. This is how you answer this. If you do so, then you will get 0.35. This shows that it is 35%. Note that when you get a decimal number, then you must multiply it by 100% to get the percentage equivalent of that number. Therefore, 7 as a percentage of 20 is 35%.

Step-by-step explanation:

Hey there!

f(x) = 7/x

<em>~ Simply keep the "7" in the place where "x" is there.</em>

f(7) =  \frac{7}{7}

Therefore, X= 1.

ira [324]

3 {a}^{2} \times  {b}^{2} \times 2ab + 6 {a}^{3} \times  {b}^{2} =

6 {a}^{3} {b}^{3} + 6 {a}^{3} {b}^{2} =

Factoring 6a^3 b^2

6 {a}^{3} {b}^{2}(b + 1)

Complete the equation for the horizontal line that passes through (5, –7).<br><br> y =
KiRa [710]

y = - 7

Step-by-step explanation:

The equation of a horizontal line is

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (5, - 7) with y- coordinate - 7, thus

y = - 7 ← equation of horizontal line

You order plant seeds from a catalog. Each packet cost 0.90 each. The shipping charge is 2.50. If you have 18.50 to spend, how m
kramer
<h2>Answer:</h2>

17

<h2>Step-by-step explanation:</h2>

Cost per Packet * Number of Packets + Shipping =  Amount to Spend

0.90 * b + 2.50 = A

You can spend a maximum of $18.50

A < 18.50

Rearrange the formula to find b

Number of Packets  =  Amount to Spend - Shipping / Cost per Packet

18.50 - 2.50 = 16.00 / 0.9 = 17.7...

You can't have 0.7 of a packet so you have to round down to 17.

Now if you put it into the original formula:

0.90 * 17 + 2.50 = 17.80

And 17.80 is less than 18.50.
