2 answers:

6 0

ANSWER: $0.78 per pound

EXPLANATION:

3 tons = $4,680.00 (this is a given)
1 ton = $1,560 (4,680 divided by 3)

We now know that we have to convert
tons —> pounds

1 ton = 2,000 pounds (simply google this)
3 tons = 6,000 pounds

Now, we can solve the problem.

$1,560 (1 pound) ÷ 2,000 (1 ton) = $0.78

TO CHECK THE ANSWER:

$0.78 • 6,000lbs = $4,680.00

There are six people at a bus stop. Each person is half the age of the next person in line. The mean age of the group is 21. How

Mice21 [21]

Answer:

The youngest person is 2 years old

Step-by-step explanation:

There are six people at a bus stop.

We are told that:

The mean age of the group is 21.

The total number of people is 6 people

Hence:

The total sum of their ages is 21 × 6

= 126

Each person is half the age of the next person in line.

Let the age of the first person be = x

The age of the second person = x/2

The age of the third person = x/2 ÷ 2 = x/2 × 1/2 = x/4

The age of the fourth person = x/4 ÷ 2

x/4 × 1/2 = x/8

The age of the fifth person = x/8 ÷ 2

x/8 × 1/2 = x/16

The age of the sixth person = x/16 ÷ 2

x/16 × 1/2 = x/32

Hence:

x + x/ 2 + x/4 + x/8 + x/16 + x/32 = 126

Lowest Common Denominator is 32

32x + 16x + 8x + 4x + 2x + x/32 = 126

63x /32 = 126

Cross Multiply

63x = 126 × 32

63x = 4032

x = 4032 /63

x = 64 years

Hence, the age of the first person is 64 years.

The age of the youngest person which is the sixth person is :

x/32

= 64/32

= 2 years

A company determines that its marginal revenue per day is given by R' ( t ) , where R ( t ) is the total accumulated revenue, in

DedPeter [7]

Answer:

Step-by-step explanation:

Total profit function is equal to Total revenue function minus Total Cost function.

To get both Revenue function and Cost function, integrate the Marginal functions as follows:

R(t) = 108.7312t^2

Where 80et = 217.4624t

(e =2.71828)

C(t) = 80t - 0.4t^2

P(t) = R(t) - C(t) = 109.1312t^2 - 80t

When t=0, P=0

When t=1, P=29.1312

When t=2, P=276.5248

When t=3, P=742.1808

And so on ...

Summing the daily profits, total profit for the 10 days is 37,615.512 dollars which equals 3,761551.2 cents

(B)

Average daily profit for the first 10 days (in dollars) is 37,615.512÷10 = 3,761.5512 dollars

= 376,155.12 cents

Gary's rental costs are $135.69, and he must pay 5 percent tax, plus $14 per day for insurance for 3 days. How much will he pay

klio [65]

5% tax of 135.69
Multiply 135.69 * .05 = 6.7845
5% tax of 135.69 is 6.78
135.69+6.78=142.47

14*3=42

142.47 + 42 = 184.47

Gary will pay $184.47 in all.

Hope this helps you! (:
