The correct answer is the last choice.

In a compound interest equation, the first value is the initial investment. In this case, it would be 5000. After the 5000, you would enter the rate that is being used.

What is 2x+3y•4 plz help me

Ray Of Light [21]

Use the distributive property to combine like terms. Since we only have one X value and one y value we need to use the 4. 2x times 4 is 4x. 3y times 4 is 6y. Now the equation can be simplified to 4x plus 6y. We have no more like terms so the equation cannot be simplified any further without more context.

Step-by-step explanation:

Total number of votes = 537

% of votes received by George Bush = 53.25 %

No. of votes recieved by George Bush = $\frac{53.25}{100}$ ×537

= 285.95

≈ 286 votes.

The rest of the votes were for John Kerry,

=537 - 286

= 251

What is the sum of an 8-term geometric series if the first term is −11, the last term is 859,375, and the common ratio is −5? −1

LekaFEV [45]

Answer:

The sum of geometric series is 716144

Step-by-step explanation:

Given

First term=a_1= -11

Last term=a_8=859375

Common ration of geometric series=r= -5

And

Total terms in geometric sequence=n=8

We know that the formula for sum of geometric series is:

S_n= (a_1 (1-r^n))/(1-r)

= (-11(1-(-5)^8)/(1-(-5))

= (-11(1-5^8))/(1+5)

= (-11(1-390625))/6

=(-11(-390624)))/6

=4296864/6

=716144

So the sum of geometric series is: 716144 ..

What is the volume of a hemisphere with a radius of 9.2 cm, rounded to the nearest tenth of a cubic centimeter?

NARA [144]

Answer:

volume of the hemisphere ≈1577.5 cm³

Step-by-step explanation:

To find the formula for calculating the volume of a hemisphere, we will follow the steps below:

write the formula for calculating the volume of a hemisphere.

volume of a hemisphere = volume of a sphere ÷2

= $\frac{4}{3}$ πr³ ÷ 2

= $\frac{2}{3}$ πr³

WHERE r is the radius

from the question given, radius= 9.2 cm

π is a constant and is ≈ 3.14

we can now proceed to insert the values into the equation

volume of a hemisphere = $\frac{2}{3}$ πr³

= $\frac{2}{3}$ × 3.14 ×9.2³

= $\frac{2}{3}$ × 3.14 ×753.571

≈1577.5 cm³ to the nearest tenth of cubic centimeter

volume of the hemisphere ≈1577.5 cm³
