Answer:

h = 1,268 cm

Step-by-step explanation:

V = (π·r²·h)/3, general formula

83 = (π·4²·h)/3, substitute what is given V= 83 cm³ and r = 4 cm

83 ·3 = (π· 16·h)·3/3, multiply both sides by 3 and solve 4² = 16

249 = π·16·h, multiply 83·3 = 249 and 3/3 = 1

249/ π·16 = h , divide both sides by π·16

1,268.146587 = h, solve

1,268 ≈ h , is rounded to the nearest cm

Parvana record's the transactions for her bank account for the week . On Monday, she made a deposit of $45. On Tuesday she used

Andrews [41]

Answer:

The correct answer is +45; -18; -7.

Step-by-step explanation:

Parvana records the transactions for her bank account for the week .

On Monday, Parvana deposited $45. Thus Parvana made an addition of $45 in her account. Therefore a +45 integer is used to represent this transaction into her account.

On Tuesday she used her debit card to $18 for a new shirt. Thus Parvana made a deduction of $18 from her account. Therefore a -18 integer is used to represent this transaction into her account.

On Thursday she withdrew $7 from an ATM. Thus Parvana made a deduction of $7 from her account. Therefore a -7 integer is used to represent this transaction into her account.

Thus the integers +45; -18 and -7 are used to represent transactions in Parwana's account.

suppose that you plan on taking a summer job selling magazines subscriptions . the magazine company will help you pay $0.75 for

alina1380 [7]

Answer:

Money earned by selling 175 magazine subscriptions will be 3176.25

Solution:

Given that you are planning to take a summer job selling magazine subscription.

For first subscription, magazine company will help you to pay $0.75

For each additional subscription sold, magazine company will pay you $0.20 more than what was paid for previous subscription.

So for second subscription, payments will be = 0.75 + 0.20 = 0.75 + 0.20 x 1

And for third subscription, payments will be = 0.75 + 0.20 = 0.75 + 0.20 x 2

Generalizing for nth subscription we get

Payments for nth subscription = 0.75 + 0.20(n-1)

so here we can see that arithmetic sequence is formed, having first term

$a_1 = 0.75$ and common difference = d = 0.20

We need to determine sum of above arithmetic sequence for n = 175

Formula for sum of arithmetic sequence is as follows 

$\mathrm{S}_{\mathrm{n}}=\frac{n}{2}[2 a+(n-1) d]$

In our case n = 175, a = 0.75, d = 0.20

$\begin{array}{l}{=>\mathrm{S}_{175}=\frac{175}{2}[(2 \times 0.75)+(175-1) 0.20]} \\\\ {=>\mathrm{S}_{175}=\frac{175}{2}[1.5+(174 \times 0.20)]} \\\\ {\Rightarrow \mathrm{S}_{175}=\frac{175}{2} \times 36.3=3176.25}\end{array}$

Hence money earn by selling 175 magazine subscriptions will be 3176.25

this isn't a test I'm just trying to make up some missing work and this one really confuses me if you guys could explain it the

skelet666 [1.2K]

Answer:

They are saying that they have this conference room mapped out on a poster board kinda like a road map. But if you put something that big on a board it wont fit. So they had to make it small enough to fit it. When they say that 1/2 on the board is equal to 12 feet in the real room, They are tell you the scale you have to go by. So then they give you 3 1/2 inches on the board. You would see how many 1/2 inches there are in 3 1/2, which is 7, and multiply 7 by 12. The answer would be 84 feet. So they are say that 3 1/2 inches on the poster board, represents 84 feet in the real room.
