Answer:

A. 31 Km

Step-by-step explanation:

circumference = 2\pi \:r

radius equals the diameter divided by 2

r =  \frac{d}{2}

In this case the diameter is 10, so the radius is 5.

finally,

2\pi(5) = 31.415

rounded to the nearest whole number gives us

31 Km.

A contractor is considering a sale that promises a profit of ​$35 comma 000 with a probability of 0.7 or a loss​ (due to bad​ we
Nady [450]

Answer:

$19,100

Step-by-step explanation:

The expected profit would be the probability of profit multiplied by the profit and the sum of probability of loss multiiplied by the loss.

So, we can say:

E(p) = P(p)*P + P(L)*L

Where

E(p) is expected profit

P(p) is probabilty of profit (0.7)

P is the profit (35,000)

P(L) is probability of loss (0.3)

L is the loss (-18,000)

Substituting these values, we get:

E(p) = P(p)*P + P(L)*L

E(p) = (0.7)(35,000) + (0.3)(-18,000)

E(p) = 19,100

The expected profit is $19,100

1: Sandy purchases a dishwasher for R6500 on a hire purchase agreement. The agreement is that the loan is to be paid off over a
Contact [7]

a) The amount Sandy will pay for the dishwasher that costs R6,500 today on hire purchase is <u>R7,772.04</u>.

b) The monthly repayments are <u>R215.89</u>.

c) The total interest paid is  R1,272.04.​

<h3>What is a hire purchase?</h3>

Hire purchase is a credit agreement that allows the buyer to make monthly payments in consideration of finance charges.

The total amount the buyer will pay periodically for the hire purchase is the cost (the price of the item) plus the total interest (finance charge).

These can be determined using an online finance calculator as follows:

<h3>Data and Calculations:</h3>

Cost of dishwasher = R6,500

Hire purchase terms = 3 years equal monthly payments

Interest rate = 12%

N (# of periods) = 36 months ( 3 x 12)

I/Y (Interest per year) = 12%

PV (Present Value) = R6500

FV (Future Value) = R0

<u>Results</u>:

Monthly payment = R215.89

Sum of all periodic payments = R7,772.04 (R215.89 x 36)

Total Interest = R1,272.04 (R7,772.04 - R6,500)

9. The formula V=lwh is the volume formula for a rectangular prism. Find the length (l) of a prism with volume (V) 1200 cm³, wid
IgorC [24]

Answer:

C. 10cm

Step-by-step explanation:

First we can rearrange the equation to solve for length (l):

V = lwh

Divide both sides by wh:

l = V/(wh)

Substitute in known values:

l = 1200/(15x8)

l = 1200/120

l = 10cm

Hope this helped!
