Answer:

-13/15

Step-by-step explanation:

104/-120 should be reduced to lowest term and - should be in the numerator

$\dfrac{104}{-120}= -\dfrac{2*2*2*13}{2*2*2*3*5}=\dfrac{-13}{15}$

Write an exponential equation to represent the situation and answer the question.

Gala2k [10]

Answer:

a. $4.48¢

b. 9,967 people

ci. Multiplier: F = 25 × (1.09)^t

cii. Percent increase = 9.15%

Step-by-step explanation:

a. The equation we are going to use to calculate the future cost of bread in 5 years:

P = F/(1+r)^t

Where P is current cost, F = future cost(what we are required to calculate), r = percentage increase per year, t = time (years).

Where P = 2.75

r = 5/100 or 0.05

t = 10

F = ?

Substituting appropriately, we have:

2.75/1 = F/(1+0.05)^10

We then cross multiply

F = 2.75 × (1+0.05)^10

F = 2.75 × (1.05)^10

F = 2.75 × 1.62889

F = $4.48¢

Therefore, the bread will cost $4.48 in 10 years.

b. Here population is 42,000 people now. There's predicted 25% decrease in population every year for the next 5years. We are to calculate the expected population in 5 years. The equation that can be used to calculate the expected population:

P = F/(1 - r)^t

F = future population

P = present population

r = percentage of decrement

t = period.

Here P = 42,000

r = 25/100 = 0.25

t = 5

F = ?

Substituting accordingly:

42000 = F/(1 - 0.25)^5

Cross multiply

F = 42000 × [(1 - 0.25)^5]

F = 42000 × 0.2373

F = 9,967

The population in the next 5 years will decrease to 9,967 people.

c. Share of orange stock = $25 in the year 2000

The same share = $60 in 2010, we are required to determine the multiplier and percent increase.

Since the future value = $60, the present value = $25, the time = 2010 - 2000 = 10 years. Then we can use the formula:-

F = P × (1 + r)^t

60 = 25 × (1 + r)^10

(1 + r)^10 = 60/25

(1 + r)^10 = 2.4

1 + r = 10√2.4

1 + r = 1.0915

r = 1.0915 - 1

r = 0.0915

r = 9.15%

Therefore the multiplier is:

F = 25 × (1.09)^t

The percent increase = 9.15%

It's due todayyyyyyy (;ŏ﹏ŏ)

Thepotemich [5.8K]

The correct answer are

Sue interest : 169.6061952

Bill interest: 189.9131472

B. Bill will get more interest then sue

Explain

Sue principal balance p= 2300

Interest for 3 years so t= 3

Interest is compounded yearly n= 1

R= 2.4%

A= 2300(1+2.4/100)^3 = 2300(1+0.024)^3 = 2300 x (1.024)^3 = 2469.6061952

Interest for 3 year is A-p= 2469.6061952 -2300

169.6061952

Bill principle p= 1800

Interest for 3 years t= 3

Interest compounded so n= 1

R= 3.4%

A= 1800(1+3.4/100)^3 = 1800 (1+0.034)^3 = 1800 (1.034)^3 = 1989.9131472

Interest in 3 yrs = 1989.9131472 - 1800 =

189.9131472

For B is below

Hopefully this help you :D

During the summer, payton and James mow the lawns in their subdivision. On each lawn they spend $3.50 on gas and $1.20 on leaf b

kirza4 [7]

Answer:

17.30 dollars

Step-by-step explanation:

Given that Payton and James mow the lawns.

They do this during summer.

The amount they spend are:

Gas cost = 3.50

Leaf bags = 1.20

Add these to get total costs

Total cost = 4.70

Charge they get per lawn = 22.00

Profit = Revenue - cost

Here revenue per lawn = 22 and cost per lawn = 4.70

Hence profit = 22-4.70 = 17.30 dollars.

Answer is they make 17.30 dollars per lawn.
