What times 3 equals 20

e-lub [12.9K]

Your question can be reworded as
? X 3 = 20.

All you do is divide by 3 on both sides to isolate the x. It basically looks like a magician makes the 3 disappear and then appear on the other side.
$\frac{?\times 3}{3} = \frac{20}{3}$
$?= \frac{20}{3}$

Tadah! We have mathmagically found the answer.

The answer is $\boxed{ \frac{20}{3}}\boxed$ in fraction form or $\boxed{6.66}\boxed$ in decimal form.

Identify the x- and y- intercept of the function f(x)=2x^2+5x-3

ycow [4]

0 = 2x^2 + 5x -3
0 = (2x-1)*(x+3)
2x-1=0 and x+3=0
X= 1/2 and x = -3

Y= 2(0)^2 + 5(0) - 3
Y = -3

The population of a town with a 20162016 population of 87 comma 00087,000 grows at a rate of 1.91.9% per year. a. Find the rate

SCORPION-xisa [38]

Answer:

Given,

The initial population, P = 87,000,

Annual rate of increasing, r = 1.9 %,

a) Thus, the population after t years,

$A=P(1+\frac{r}{100})^t$

$A=87000(1+\frac{1.9}{100})^{t}$

$=87000(1+0.019)^t$

$=87000(1.019)^t$

$87000(1.019)^t=87000e^{kt}$

Where, k is the rate constant,

By comparing,

$\implies k=log(1.019)=0.00817418400643\approx 0.00817$

Hence, the approximate value of k is 0.00817.

And, the exponential growth function would be,

$A=87000e^{0.00817t}$

b) If A = 145,000,

$145000=87000(1.019)^t$

By using graphing calculator,

We get,

$t=27.14\approx 27$

The year after 27 years from 2016 is 2043.

Hence, in 2043 the population reach 145,000.

What whole number does this round to?

serious [3.7K]

To find this answer, just look at the place value next to the one you are trying to find.

You are trying to find the whole number (or 7). The place value digit to the right is 4, which is less than 5. Round down

Your answer is 7
