Find the Volume of the cone​
Karolina [17]

Answer:

<h2>1005.12</h2>

Step-by-step explanation:

<u>first</u><u> </u><u>we </u><u>need</u><u> to</u><u> </u><u>know</u><u> that</u><u> </u><u>r</u><u>edious</u><u> </u><u>isn't</u><u> </u><u>gien</u>

so we have to find redious

according to Pythagoras theorem

a²+b²=c²

a=√c²-b²

a=17²-15²

a=√(17+15)(17-15)

a=√64

a=8

as \: we \: khow \: volume \: of \: a \: cone

=  \frac{1}{3} \pi {r}^{2} h

\frac{1}{3} \pi \times  {8}^{2}  \times 15

\frac{\pi}{3}  \times 64 \times 15

\pi \times 64 \times 5

3.141 \times 64 \times 5

This is 210 dollars more than the static graders, but only 4/5 as much as the stactic graders. For every 60 dollars the teachers
lesya692 [45]

The teachers plan will raise money is 1.8 times the static graders plan.The teachers plan to raise a dollar is 5/6 times the static graders plan to raise a dollar.More dollars will be raised by the teachers plan compared to the static graders plan.

Step-by-step explanation:

In the question,

Let what the static graders plan to rise to be $x.

Let what the teachers plan to rise to be $ y

You understand that ;

y =210 +x ----------------(this is 210 dollars more than the static graders raise)

y=x+4/5 x -------------------(but only 4/5 as much as the static graders)

Solving the equations to get x and y

210+x=x+4/5x

5(210+x)=5*x+4x

1050+5x=5x+4x

1050=5x+4x-5x

1050=4x

1050/4=4x/4

x=$262.50

y=210+262.50=$472.50

Additionally, for every $60 raised in teachers plan, the static graders raise $50

This means in teachers plan 1$ raised equals 5/6$ raised in static plan

y=5/6x

What is the simplified expression for 4 power 4 multiplied by 4 power 3 over 4 power 5?
Rus_ich [418]
(4^4 * 4^3) / 4^5 = 

when multiplying exponents with the same base, add the exponents
(4^4 * 4^3 = 4^(4 + 3) = 4^7

now we have 4^7 / 4^5

when dividing exponents with the same base, u subtract the exponents.
4^7 / 4^5 = 4^(7-5) = 4^2 <===
