The answer is 31 why? you replace the variable with -3
So it's f (a)=-2 (-3)(2)-5 (-3)+4
f (a)=31 that is the final answer.
Answer:
27.5%
Step-by-step explanation:
Given:
- 1 Liter In Teapot
- Alex poured 275 milliliters of the tea into a cup
Review:
- 1,000 Milliliters = 1 Liter
Concepts:
- A liter is a noun meaning a unit of capacity redefined in 1964 by a reduction of 28 parts in a million to be exactly equal to one <em>cubic </em>decimeter. It is equivalent to <em>1.0567</em> U.S. liquid <u>quarts </u>and is equal to the volume of 1 kilogram of distilled <em>water</em> at 4°C.
- A millimeter is a noun meaning a unit of capacity <em>equal</em> to one <u>thousandth </u>of a liter, and equivalent to <em>0.033815</em> fluid<u> </u><u>ounce</u>, or<em> 0.061025</em><em> </em>cubic<u> inch</u>.
Formula:
- The <em>mℓ</em> to <em>ℓ</em> formula is<em> [L] = [mL] / 1000</em>.
Now we must convert <em>275</em> milliliters to liters.
1. Divide the volume by <em>1,000.</em>
275 ÷ 1000 = 0.275
2. Add the Unit Symbol for Liter.
0.275 ⇒ 0.275 L
Now we have to find how much of 1 liter- 0.275 liters as a percentage is.
To convert <em>0.275</em> to percent multiply <em>0.275</em> by <em>100</em>. The result is <em>27.5 </em>percent, or, using the percent sign, <em>27.5 %.</em>
75 (your whole) / .55 (percentage) =41.25
