answer : -2400 π

Step-by-step explanation:

dr/dt = -12 km/s

h = 2.5 km

r = 40 km at some instant

hence the rate of change of Volume of cylinder at that instance

= dv / dt = [tex]d(\pi r^h ) / dt[/tex]  

              = [tex]\pi h\frac{d(r^2)}{dt}[/tex]  = [tex]-\pi h *2r *dr/dt[/tex]

hence ; dv / dt = -2400 π

Answer:

32%

Step-by-step explanation:

Olivia's cell phone bill last month was $125. This month her bill is $85. What is the percent of change in Olivia's bill?

The formula for Percent change =

Amount of change/Original amount × 100

Amount of change = Original amount = New amount

Original Amount/bill = $125

New amount/bill = $85

= $125 - $85

= $40

Percent change = $40/$125 × 100

Percent change = 0.32 × 100

Percent change = 32%

Therefore, the percent of change in Olivia's bill is 32%

Answer:

63m - 42

Step-by-step explanation:

Rewrite each given equation as

[tex]p=q^r\implies \log_p(p)=\log_p(q^r)\implies 1=r\log_p(q)\implies r=\dfrac1{\log_p(q)}=\dfrac{\ln(q)}{\ln(p)}[/tex]

[tex]q=r^p\implies \log_q(q)=\log_q(r^p)\implies 1=p\log_q(r)\implies p=\dfrac1{\log_q(r)}=\dfrac{\ln(r)}{\ln(q)}[/tex]

[tex]r=p^q\implies \log_r(r)=\log_r(p^q)\implies 1=q\log_r(p)\implies q=\dfrac1{\log_r(p)}=\dfrac{\ln(p)}{\ln(r)}[/tex]

where each of the last equalities follows from the change-of-base identity,

[tex]\log_m(n)=\dfrac{\log_b(n)}{\log_b(m)}[/tex]

for any base b > 0 and b ≠ 1. I picked the natural base, e.

Then

[tex]prq=\dfrac{\ln(r)}{\ln(q)}\times\dfrac{\ln(q)}{\ln(p)}\times\dfrac{\ln(p)}{\ln(r)}=1[/tex]

as required.

Answer:

11

Step-by-step explanation:

let the first number be n , then the second number is 5n and

the third number is 5n - 14

Sum the numbers and equate to 41

n + 5n + 5n - 14 = 41

11n - 14 = 41 ( add 14 to both sides )

11n = 55 ( divide both sides by 11 )

n = 5

Thus

first number = 5

second number = 5n = 5 × 5 = 25

third number = 5n - 14 = 5(5) - 14 = 25 - 14 = 11

Answer:

-53/12

Step-by-step explanation

If you break it down it looks like this:

-23/3 + (-11/2) + 35/4

multiply them so that all their denominators are a similiar multiple (which is 12)

-92/12 - 66/12 + 105/12 = -53/12

Answer:

(4x²y³)² 8 x⁴y⁵ 8 x⁴ y⁶ 16  x⁴ y ⁵ 16 x⁴ y⁶  = 262,144 x²⁰ y²⁸

Step-by-step explanation:

Given

          (4x²y³)² 8 x⁴y⁵ 8 x⁴ y⁶ 16  x⁴ y ⁵ 16 x⁴ y⁶  

we know that

     [tex]a^{m} X a^{n} = a^{m+n}[/tex]

     [tex](a^{m} )^{n} = a^{mn}[/tex]

   =  (16x⁴y⁶ 8 x⁴y⁵ 8 x⁴ y⁶ 16  x⁴ y ⁵ 16 x⁴ y⁶  

   = 16 ×8×8×16×16 x⁴⁺⁴⁺⁴⁺⁴⁺⁴ y⁵⁺⁶⁺⁵⁺⁶⁺⁶

 = 262,144 x²⁰ y²⁸

5. (1296)

6. (25)

7. (4.305)

8. (120)

9. (529)

10. ($2.59)

Step-by-step explanation: For 1 I just used a calculator, for 2 it is just going to be 12-9 which is 3, for 3 it is 5/2 x 7/3, make the denominators the same getting 15/6 x 14/6 and getting 210, now divide by 6 getting 35, for 4, it is -3-10 which is -13, for 5 do 6x6x6x6 which equals 1296,  for 6 do 48-23 = 25, for 7 just divide, I used a calculator, for 8, multiply 20 by 12 and get 240, now divide by 2 which is 120. for 9 do 23x23 which is 529, for 10, divide 12.59 by 5 and get an answer of 2.59.    HOPE THIS HELPED!

$260

Step-by-step explanation:

GIven

P=$250

R=4%

T=1 year

The total amount of simple interest is

A=P(1+rt)

substitute

A=250(1+0.04*1)

A=250(1.04)

A=250*1.04

39% as a fraction in its lowest form is 39/100.

To express 39% as a fraction in its lowest form, we need to divide the percentage by 100 and simplify the resulting fraction.

The percentage symbol "%" means "per hundred," so 39% can be written as 39/100.

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor (GCD).

Here, the GCD of 39 and 100 is 1, so we divide both numbers by 1:

= 39 ÷ 1 / 100 ÷ 1

= 39/100

Therefore, 39% as a fraction in its lowest form is 39/100.

Answer:

42 games

Step-by-step explanation:

From the ratio, we can deduce that;

For every 3 games A won, B won 1

Thus, if B won 10, then A has won 3(10) = 30

From the second part;

For every 1 game won by C, B won 5

since B won 10, then C won 10/5 = 2

So the total number of games won is;

A + B + C

= 2 + 30 + 10 = 42 games
