Solve the equation 5.13(10)2.3x = 400. To do so, set the left side equal to y and the right side equal to y. Open the graphing t

leva [86]

Answer:

x=0.823

Step-by-step explanation:

We are given equation as

$5.13(10)^{2.3x}=400$

now, we can find two equations

First equation is

$y=5.13(10)^{2.3x}$

And second equation is

$y=400$

now, we can draw graph

and then we can find intersection points

we get

(0.823,400)

so,

x=0.823

In a population of 3 1/4 million people, 2115000 are under the age of 16. Calculate the percentage, to two decimal places, of th

Masteriza [31]

So what we need to do is divide the number of people under 16 by the number of the entire population:

$\frac{2115000}{3250000}$

first, let's get rid of the 0s:

$\frac{2115}{3250}$

now, we can divide:
this is 0.6507....

in order to make this into a percentage, we multiply by 100%:

0.6507*100%=65.07%

the answer is: 65 % (quite a lot!!!)
