Y=2x+320
x being the number of years and 320 being the initial population of mice
Answer:
The number is <u>20</u>.
Step-by-step explanation:
In this question, it is said that 35% of a number is equal to 7, then what is that number?
So, let the number be <em>x</em>.
Now, according to the question :

Hence, the number is 20.

You are only showing one pair of triangles
Answer: 2*√18 + 3*√2 + √162 = 18*√2
Step-by-step explanation:
I guess that the equation is:
2*√18 + 3*√2 + √162
And we want to simplify it.
first 18 = 9*2
then we can write:
2*√18 = 2*√(9*2) = 2*3*√2 = 6*√2
and 162/9 = 18
then we can write:
√162 = √(9*18) = √9*√18 = 3√18
now we can use the previous step: √18 = 3*√2
and:
√162 = 3*(3*√2) = 9*√2
now we can write our equation as:
6√2 + 3√2 + 9√2 = (6 + 3 + 9)√2 = 18*√2
And now we can not simplify it further more, so here we end.
Step-by-step explanation:
Y varies directly as cube root of x is written as
y = k³√x
where k is the constant of proportionality
<h2>A).</h2>
when y = 3
x = 27
We have
![3 = k \sqrt[3]{27}](https://tex.z-dn.net/?f=3%20%3D%20k%20%5Csqrt%5B3%5D%7B27%7D%20)
But ³√27 = 3
That's
3 = 3k
Divide both sides by 3
k = 1
<h3>The value of the constant is 1</h3>
<h2>B).</h2>
The value of the relationship is
<h2>
![y = \sqrt[3]{x}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Csqrt%5B3%5D%7Bx%7D%20)
</h2>
<h2>C).</h2>
When x = 8
We have
<h2>
![y = \sqrt[3]{8}](https://tex.z-dn.net/?f=y%20%3D%20%20%5Csqrt%5B3%5D%7B8%7D%20)
</h2>
<h3>y = 2</h3>
Hope this helps you
