F/g(x) = (2x^2 + 5x - 1)/(x + 3)

f/g(4) = (2(16) + 5(4) -1)/(4 + 3)

Safia opens a new savings account with a 2.25% simple interest rate. She deposits $3,500 and earned $3,696.88 total (with intere
Art [367]

Answer:

The money was left untouched for 2 years and 6 months or just 2.5 years

Step-by-step explanation:

In this question, we are asked to calculate the time taken for an amount deposited to earn a certain amount of interest.

Mathematically, simple interest can be calculated using the formula;

I = PRT/100

where I is the interest accrued which is 3696.88 - 3,500 = 196.88

P is the principal which is the amount deposited = 3,500 according to the question

R is the rate which is 2.25% according to the question

T is the time which we are to find

we can rearrange the formula making T the subject and we obtain the following;

T = 100I/PR

substituting the values listed above we have;

T = (100 * 196.88)/(3500 * 2.25)

T = 19688/7875

T = 2.5 years or 2 years 6 months

statuscvo [17]

Answer: 45

Step-by-step explanation:

In​ 2016, 1 out of every 5 people under the age of 50 used a cell phone to read​ e-books. This means that 2 out of every 10 people under the age of 50 used a cell phone to read​ e-books. Also, 3 out of every 15 people under the age of 50 used a cell phone to read​ e-books.

Therefore, if there were x people under the age of 50 in​ 2016, then the number that used a cell phone to read​ e-books would be

1/5 × x = x/5

If there were approximately 225 million people under the age of 50 in​ 2016, then the number that were likely to have read an​ e-book on a cell​ phone is

225/5 = 45 people.

The monthly cost of a short term disability insurance policy varies directly as the salary of the employee. Wanda has an annual
arlik [135]

Answer: $14.85

Step-by-step explanation:

Ww can solve the question using direct proportion with the formula y = kx

where y = annual salary

x = monthly policy cost.

k = constant of proportionality

Since y = kx

38500 = 11.55k

k = 38500 / 11.55

k = $3333.33

When Randy has an annual salary of $49,500, the amount Randy expect to pay for his policy will be:

y = kx

49500 = 3333.33x

x = 49500 / 3333.33

x = 14.85

The amount that Randy expect to pay for his policy will be $14.85
