Answer:
$13.67 - $11.50
So the raise over 7 years was $2.17
So to find the annual raise in the wage:
$2.17 / 7 = 0.31
His wage was raised <u>.31 every year</u>.
Step-by-step explanation:
substitute for y
x+3+4 = -6x
x+ 7 = -6x
7 = -7x
-1 = x
y = -1+3
y = 2

Answer:
Option c. 11,488.21 cm3
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The volume of the sphere is equal to
![V=\frac{4}{3}\pi r^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E%7B3%7D)
we have
---> the radius is half the diameter
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
substitute
![V=\frac{4}{3}(3.14)(14)^{3}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7B4%7D%7B3%7D%283.14%29%2814%29%5E%7B3%7D)
![V=11,488.21\ cm^3](https://tex.z-dn.net/?f=V%3D11%2C488.21%5C%20cm%5E3)
