What is 15 increased by 60%

vazorg [7]

What is 15 increased by 60 percent? Let's work it out!

First, you must know what 60 percent of 15 is.

60 percent of 15
 15 times .60
equals
9.

So 60% of 15 is 9.

Increased is a word which means added.

So, 15 plus 9 (15+9) is 24.

Final Answer = 24.

Hope I could help!

A sphere has a radius of 11 feet. A second sphere has a radius of 8 feet. what is the difference of the volume of thespheres

Veronika [31]

The difference between the volume of the spheres is 3428.88 cubic feet

Explanation:

Given that one sphere has a radius of 11 feet.

A second sphere has a radius of 8 feet.

Volume of the 1st sphere:

The formula to determine the volume of the sphere is given by

$V=\frac{4}{3} \pi r^3$

Volume of the 1st sphere is given by

$V=\frac{4}{3}(3.14)(11)^3$

$V=\frac{4}{3}(3.14)(1331)$

$V=\frac{16717.36}{3}$

$V=5572.45$

The volume of the 1st sphere is 5572.45 cubic feet.

Volume of the 2nd sphere:

Volume of the 2nd sphere is given by

$V=\frac{4}{3}(3.14)(8)^3$

$V=\frac{4}{3}(3.14)(512)$

$V=\frac{6430.72}{3}$

$V=2143.57$

The volume of the 2nd sphere is 2143.57 cubic feet.

Difference between the volume of the two spheres:

Difference = Volume of the 1st sphere - Volume of the 2nd sphere

= 5572.45 - 2143.57

Difference = 3428.88 cubic feet.

Hence, the difference between the volume of the spheres is 3428.88 cubic feet.

If a certain canon is fired from a height of 8.9 m above the ground, at a certain angle, the height of the Campbell above the gr

qwelly [4]

Answer:

T=5.9235 seconds

Step-by-step explanation:

$H(T)= -4.9T^2+27.52T+8.9.$

The time it takes for the cannonball to strike the ground is the point at which H(T)=0

$H(T)= -4.9T^2+27.52T+8.9.=0$

$-4.9T^2+27.52T+8.9=0$

This is a quadratic equation and since we have a bunch of decimals we use the quadratic formula:

$x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}$

a=-4,9, b=27.52, c=8.9

$T=\dfrac{-27.52\pm\sqrt{(-27.52)^2-(4*-4.9*8.9)} }{2*-4.9}\\=\dfrac{-27.52\pm\sqrt{757.3504-(-174.44)} }{-9.8}\\=\dfrac{-27.52\pm\sqrt{931.7904} }{-9.8}\\=\dfrac{-27.52\pm30.53 }{-9.8}\\T=-0.3071 \:or\: 5.9235\\T=5.9235 seconds$

It takes 5.9235 seconds for the cannonball to strike the ground.
