# ____INVERSE PROPORTION_____ HELP ME FOR LOTS OF POINTS AFTER THIS THERE ARE MORE QUESTIONS URGENT! F is inversely proportional to d squared When F=8 d=6 Work out d (positive value rounded to 2 DP) when F=9

d ≈ 5.66

Step-by-step explanation:

given that F varies inversely with d squared, then the equation connecting them is

F = ← k is the constant of variation

to find k use the condition when F = 8, d = 6

k = Fd² = 8 × 36 = 288, hence

F =

when F = 9, then

9 = ← multiply both sides by d²

9d² = 288 ( divide both sides by 9 )

d² = 32 ( take the square root of both sides )

d = ± , hence

d ≈ 5.66 ← positive value only

How many coulombs pass a point in 0.1 seconds when the current is 1.5 A

The coulomb is the standard unit of electric charge.

0.15 coulombs pass a point in 0.1 seconds when the current is 1.5A.

What is a coulomb?

The coulomb is the standard unit of electric charge.

One coulomb is equal to the amount of charge from a current of one ampere flowing for one second.

We have,

C = As ____(1)

C = coulomb

A = current in amperes

s = time in seconds

t = 0.1 seconds

A = 1.5A

From (1) we get,

C = As

C = 1.5 x 0.1

C = 0.15

Thus, 0.15 coulombs pass a point in 0.1 seconds when the current is 1.5A.

A coulomb is a measure of charge and current is the rate of flow of charge.

There is a formula linking the three quantities (charge=Q; T=time; I=current):

Q=I x T

1.5A x 0.1s= 0.15C

The ratio 21:28 in simplest form is

3:4 will be the correct answer in simplist form

21 and 28 are both divisible by 7
So 21/7=3
And 28/7=4
So the ratio in simplest form is 3:4

Which of the following numbers would be an outlier if added to the data below? 372, 351, 299, 406, 387, 315, 364,308

299 will be the outlier

Step-by-step explanation:

If u were to add em all plus the outlier, it will be 2802, then divide it by 8 to get 350.25. I we did it without the outlier it will be 2503 then divide by 7 is 357.57. S therefore 299 is the outlier.

Solve 9(4g + 9) using the distributive property. Can someone help me with this and show their work?

36g + 81

Step-by-step explanation:

9 is your multiplier.  Multiply each of the two terms inside the parentheses by this 9, one at a time:

36g + 81

9 (4g + 9) = 9*(4g) + 9* (9) = 36g + 81

Step-by-step explanation:

A swimming pool in the shape of a rectangular prism is 30 feet long , 15 1/2 feet wide , and 6 feet deep. How much water could the swimming pool hold

The Swimming Pool can hold 2,790 of water.

Step-by-step explanation:

The amount of water a rectangular prism can hold is measured by the volume it has. Volume is calculated with the following formula.

In which L is the length, W is the width, and H is the height of the rectangular prism. Given that we have all this information, we can plug it into the formula to get the volume.

So the Rectangular Prism Swimming Pool has a volume of 2,790 meaning it can hold that amount in water.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

To find how much water that can fit, you need to find the volume of the pool by multiplying the length by the width by the deepness.

30 × 15.5 × 6 = 2790

The pool can hold 2790 cubic feet of water

40.79 divided by 6.7

The answer would be 6.08 consider the numbers behind the decimals as they will be helpful to know where to put your decimal point in your answer. Hope this helps!

The final answer would be 5.16
