Answer:
The Markup was by 25%
Step-by-step explanation:
The answer is 25% because 25% of 64 is 16
25% * 64 = 16
64 + 16 = 80
So, the price markup was by 25%
Hope this helps! :)
Answer: 6x +18x - 6= -12
24x - 6 = -12
+6= +6
24x = 6
X= 4
Answer:
291.
Step-by-step explanation:
(x - 147) / 12 = 12
x - 147 = 144
x = 144 + 147
x = 291.
Answer:
6 inches
Step-by-step explanation:
3392.92 cubic inches of liquid distributed in 30 spheres would give each sphere's volume to be:

Now we equate 113.1 to the formula for volume of a sphere and solve for r:
![\frac{4}{3}\pi r^3=113.1\\r^3=\frac{113.1}{\frac{4\pi}{3}}\\r^3=27\\r=\sqrt[3]{27} =3](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3%3D113.1%5C%5Cr%5E3%3D%5Cfrac%7B113.1%7D%7B%5Cfrac%7B4%5Cpi%7D%7B3%7D%7D%5C%5Cr%5E3%3D27%5C%5Cr%3D%5Csqrt%5B3%5D%7B27%7D%20%3D3)
The radius of each of those spheres is 3
We know diameter is twice the radius , so diameter would be 3 * 2 = 6 inches
We know that
<span>the equation of the circle in standard form is
(x-h)</span>²+(y-k)²=r²
where
(h,k) is the center of the circle
and
r is the radius
in this problem
(h,k) is
<span>(8, 0)
and radius r=</span>√3 units
so
(x-h)²+(y-k)²=r²-----> (x-8)²+(y-0)²=(√3)²---->(x-8)²+y²=3
the answer is(x-8)²+y²=3
