Answer:

l = 10.5 units

Step-by-step explanation:

P = 34 [Perimeter]

W = 6.5 {let's use W and L to make it easy to read]

Also known:

P = W + L + W + L = 2(W+L)

Fill in values:

34 = 2(6.5+L) [NOTE: This is an equation to determine the length (L) of the rectangle."]

. . .

17 = 6.5 + L [NOTE: This is a simplified form of the above equation.]

. . .

10.5 = L [NOTE: This is the solution (the value of L)]

I would assume that the author of this question is not interested in simply getting the answer (so L=10.5 alone would be incorrect) or in the process, but simply in CORRECTLY "SETTING IT UP," KNOWING THAT P=2(W+L).]

McKenzie buys 240 shares of stock for $12 a share and pays a 1% commission. She sells the stock 3 years later for $18 a share an

schepotkina [342]

Answer:

The total amount made would be $1,324.80

Step-by-step explanation:

First we need to find the total amount invested. To find that, we multiply the price of the stock by the amount of shares.

$12 * 240 = $2,880

And then we need to add the commission. So we multiply by 1% and add that to the cost.

$2,880 * 1% = $28.80

$2,880 + $28.80 = $2,908.80

Now we follow the same process for the selling. First multiply the cost by the number of shares.

$18 * 240 = $4,320

This time, we subtract the commission.

$4,320 * 2% = $86.40

$4,320 - $86.20 = $4,233.60

Now we take the amount from the selling and subtract the total investment to see how much we made.

$4,233.60 - $2,908.80 = $1,324.80

A soup bowl is in the shape of a hemisphere with a diameter of 10 cm. What is the approximate maximum volume of soup that the bo

LUCKY_DIMON [66]

Answer:

C. 262 cm

Step-by-step explanation:

Use the formula for the volume of a sphere, V = $\frac{4}{3}$ $\pi$ r³

Since the diameter is 10 cm, the radius will be 5 cm

Plug in the radius into the formula:

V = $\frac{4}{3}$ $\pi$ (5³)

V = $\frac{4}{3}$ $\pi$ (125)

V = 523.6

Since the bowl is a hemisphere, divide this by 2:

523.6/2

= 261.8

Rounding to the nearest cm, the volume of the bowl is 262 cubic cm.

So, the correct answer is C. 262 cm
