The number of different cars sold in some country rose from 210 in 1997 to 277 in 2007. Find the percent increase. Round to the

Virty [35]

Find percent increase by subtracting the amounts and dividing it by the old amount, then multiply the result by 100 to make it a percent.

Increase= (277-210)/210

67/210

Then it ends up as 0.319047619...

Multiply that by 100 to make it a percent, which is..

31.9047619..

Round it off, and you get..

32%!

How many liters are in 21 cups? if 1L=4.2cups<br> i don't understand how to do it

Luda [366]

Answer:

5 L

Step-by-step explanation:

As given in question,

1 L can fill 4.2 cups.

So, 1 cup can hold $\frac{1}{4.2}$ L of fluid.

Therefore,

21 cups can hold = $\frac{1}{4.2}$ × 21

= 5 L

So, there is 5 L of fluid in 21 cups.

MRS Quirk buys 1 quart of milk. michael drinks 2/7 of it. Joel drinks 1/3 of it. what fraction of the quart of milk is left

erica [24]

13/21 cause 21 is a common denominator and 7x3+ 21 you have to do 7x=7 and 3x7=21 so you have to do 3x2= 6 so you do 6+7 which equals 13 and your answer is 13 over 21 since it can't be simplified

What is the discontinuity and zero of the function f(x) = 3x^2 + x - 4 / x-1

7nadin3 [17]

Ans: Option (1) <span>Discontinuity at (1, 7), zero at ( negative four thirds , 0)
</span>
Explanation:
Given function:
$f(x) = \frac{3x^2 + x - 4}{x-1}$

Now if we plug in the x = 1, we would have discontinuity as function goes to infinity.

Now for f(1):
$f(x) = \frac{3x^2 + x - 4}{x-1} \\ f(x) = \frac{3x^2 + 4x - 3x - 4}{x-1} \\ f(x) = \frac{x(3x+4)-1(3x+4)}{x-1} \\ f(x) = \frac{(x-1)(3x+4)}{(x-1)} \\ f(x) = 3x+4 \\ now ~ insert ~ x=1: \\ f(1) = 3(1) + 4 = 7 \\ It~means~discontinuity~at~(1,7).\\ Now~let~us~find~zeros.\\ put~ f(x) = 3x+4 ~ equals~ to ~zero. \\ =\ \textgreater \ ~3x+4 = 0 \\ =\ \textgreater \ ~ x = \frac{-4}{3} \\ Hence~zeros=( \frac{-4}{3}, 0)$
