3(2t+5)=5t+25

Multiply the bracket with 3

(3)(2t)(3)(5)=5t+25

6t+15=5t+25

Move 5t to the other side. Sign changes from +5t to -5t

6t-5t+15=5t-5t+25

6t-5t+15=25

Move +15 to the other side. Sign changes from +15 to -15

6t-5t+15-15=25-15

6t-5t=10

1t=10

divide by 1

1/1t=10/t

t=10

Answer: t=10

Answer:

t=10

Step-by-step explanation:

3(2 t + 5) = 5 t + 25

Multiply parenthesis by 3 ^^^

6t + 15 = 5t + 25

move terms^^

6t - 5t = 25 - 15

collect the terms

and subtract

A hollow sphere sits snugly in a foam cube so that the sphere touches each side of the cube. Find the volume of the foam.
ExtremeBDS [4]

Answer:

                             π

V-foam = 4r³( 2 - ----- )

                             3

Step-by-step explanation:

Let the radius of the sphere be r.  Then the volume of the sphere is

V = (4/3)(π)(r³).  

Next, recognize that the side length of the cube is 2r, and that the volume of the cube is thus

V = (2r)³, or 8r³.

Then the volume of the foam is equal to the volume of the cube less the volume of the sphere:

V-foam = 8r³ - (4/3)(π)(r³).  This could be factored into

                             π

V-foam = 4r³( 2 - ----- )

                             3

Between x=2 and x=3, which function has a greater average rate of change than f(x)=2^x has?
maxonik [38]

Answer: f(3)

Step-by-step explanation:

First find the formula for the rate of change by taking the derivative of 2^x. Let f(x) equal some hypothetical y-value, then take the natural log of both sides.

y=2^x\\\ln(y)=x \ln(2)

Implicitly differentiate the left side and take the derivative of the right side

\frac{y'}{y} =\ln(2)

Multiply both sides by 'y' which was defined as 2^x

y'=\ln(2)*2^x

Plug in x = 2 and x = 3 to see which slope is larger

y'=\ln(2)*2^2=4\ln(2)\\y'=\ln(2)*2^3=8\ln(2)

Answer:

  5450

Step-by-step explanation:

Put 9% where r is in your formula and evaluate it. Of course, you must use the decimal equivalent.

  5000(1 +9%) = 5000(1.09) = 5450

The account will have 5450 in it at the end of the year.
