Answer:

[tex]V=\pi r^2h=\pi *6^2*19[/tex] ≈ [tex]2148.8[/tex]

Let me know if you found this helpful! It means a lot!

Answer 2
Answer:

2148.9 m^3

Explanation:

The formula for the volume of a sphere is V=πr^2h

We know that r, the radius, is 6 metres.
We also know that h, the height is 19 metres.

If we substitute those values into the formula, we get 2148.85 m^3.

And 2148.85 to the nearest tenth is 2148.9 m^3.

Answers

Answer:

C

Step-by-step

The amount of the annual withdrawals will be $16,574.24.

The given data in the problem is;

P = annual payment

PV= present value = $150,261

r= rate of intreast = 9.1% =9.1/100= 0.091

n = time period= 20

What is the formula for the annual payment ?

[tex]P=\frac{r\times PV}{1-(1+r)^{-n}}[/tex]

[tex]P=\frac{0.091\times 150261}{1-(1+0.091)^{-20}}[/tex]

[tex]P=16754.24[/tex]

Therefore, the amount of the annual withdrawals will be $16,574.24.

Can someone explain to me how to use square root? How do I solve it? How do I use it? I'm not sure the right way to use square root and I have testing soon, so I wanted to know how to use it beforehand.

Answers

Answer:  a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x. For example, 4 and −4 are square roots of 16, because 4² = ² = 16

The square of any number is always a positive number, so every number has two square roots, one of a positive value, and one of a negative value. For example, both 2 and -2 are square roots of 4.

Answers

Using the dot plot, the inference is that the number of flocks observed on the second day was less than in the first.

What does a dot plot show?

The dot plot shows the number of times each measure appears in the data-set.

Hence, the mean of the data-set corresponding to day 1 is given by:

M1 = (4 x 4 + 7 x 5 + 7 x 6 + 7 x 7)/25 = 5.68

And the mean of the data-set corresponding to day 2 is given by:

M2 = (2 x 8 + 3 x 7 + 4 x 6 + 5 x 4)/25 = 3.24.

M1 > M2, hence, the inference is that the number of flocks observed on the second day was less than in the first.

Type your answer into the box. Butter and flour are mixed in the ratio 2:3. Chris has 640 grams of butter and 880 grams of flour. How much more flour does he need? ​

Answers

Answer:

80 grams

Step-by-step explanation:

since butter & flour are in the ratio 2:3

2/5 = 640

then 3/5 = flour(?)

eliminate 5 since it is common so that

2= 640

3= x

cross multiply

x= 3 /2× 640

= 960

640 grams of butter needs to mix with 960grams of flour so that they can be in the ratio of 2:3

960-880 = 80

hence 80 more grams of flour are needed.

HELPPPP Two planes leave the airport at noon, one traveling east at 300 km/h and the other traveling northwest at 45 km/h. How far apart are they at 2 pm?

Answers

How far both planes travelled is an illustration of distance

Both planes are 510 km apart at 2 pm

How to determine their distance apart?

The rates of the two planes are given as:

Plane A = 300km/h

Plane B = 45km/h

Calculate the difference (r) in their rates

r = 300km/h - 45km/h

This gives

r = 255km/h

At 2 pm, both planes have travelled for 2 hours.

So, the distance between them is:

d = 255 * 2

d = 510km

Hence, both planes are 510 km apart at 2 pm

B. Price of Buying:

Answers

Using simple interest, it is found that the prices are as follows:

A. $10,200.

B. $12,614.58.

Simple Interest

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

[tex]A(t) = A(0)(1 + rt)[/tex]

In which:

A(0) is the initial amount.r is the interest rate, as a decimal.

Item a:

$850 for 12 months, hence the yearly cost is:

P = 850 x 12 = $10,200.

Item b:

The total cost is found using simple interest with A(0) = 175000, t = 30, r = 0.03875, hence:

A(t) = A(0)(1 + rt)

A(30) = 175000[1 + 0.03875(30)]

A(30) = 378437.5.

The yearly cost is given by:

378437.5/30 = $12,614.58.
