So you just divide $255 by 20 hours and then solve it. The answer should be $12.75/hr
7x^2 - 12 = 0
7x^2 = 12 | : 7
x^2 = 12/7 | sqrt
x = sqrt(12/7)
x = sqrt(84) / 7
x = 2sqrt(21) / 7
Answer:
y = 5x
Step-by-step explanation:
The equation for direct variation is y = kx, where k is the factor of variation. So we know that y and x must fit into this formula.
They've given us a y and x value to solve for k.
y = kx
15 = 3k
15/3 = k
<u>k = 5</u>
Plug k back into our equation.
y = 5x
Answer:
-7/5
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 1-8)/(7-2)
= -7/5
Hence if we covert 28,500,000 in scientific notation and write in the form then x is equal to 7.
What is scientific notation?
Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form.
Given number is 28500000
we can write 28500000 as
or we can write it as
and now we can write it in Scientific notation form as
So x=7
Hence if we covert 28,500,000 in scientific notation and write in the form then x is equal to 7.
