2500 dollars is placed in an account with an annual interest rate of 7.25%. To the nearest year, how long will it take for the account value to reach 13100 dollars?
please help!^^

Answers

Answer:

about 58 years 6 months

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 7.25%/100 = 0.0725 per year,

then, solving our equation

t = 10600 / ( 2500 × 0.0725 ) = 58.4828

t = 58.4828 years

The time required to

accumulate simple interest of $ 10,600.00

from a principal of $ 2,500.00

at an interest rate of 7.25% per year

is 58.4828 years (about 58 years 6 months).

Answer:

5 years

Step-by-step explanation:

Find out how much you earn a year from interest and money.

Find 1%.

100% = 2500

1% = 2500 ÷ 100 = 25

7.25% = 25 x 7.25 = 181.25

2500 + 181.25 = 2681.25

Now divide how much you earn from money and interest from 13100.

13100 ÷ 2681.25 = 4.88

4.88 estimated to 5

Sonia works at a bakery. The function f(x) represents the amount of money in dollars Sonia earns per loaf, where x is the number of loaves she makes. The function g(x) represents the number of bread loaves Sonia bakes per hour, where x is the number of hours she works.

f(x) = 9x2 + 1

g(x) = the square root of two times x cubed

Find f(g(x)).

f(g(x)) = 18x3 + 1 dollars over hour
f(g(x)) = 18x3 + 1 loaves over hour

a certain number of two digit is three times the sum of its digit and if 45 added to it the digit will be reversed find the number ?​

Answers

Let the number be (10 x + y)

Then, 10 x + y = 3 * (x + y) (given)

Or, 10 x + y = 3 x + 3 y

Or, 10 x - 3 x = 3 y - y

Or, 7x = 2 y

Or, x = 2 y / 7 ( Eq. 1)

Also, 10 x + y + 45 = 10 y + x ( given)

Or, 10 x - x = 10 y - y - 45

Or, 9 x = 9 y - 45 ( Eq. 2)

Substituting the value of x from (Eq. 1) in (Eq. 2), we have:

9 * 2 y / 7 = 9 y - 45

Or, (9 y ) - (18 y / 7) = 45

Or, 63 y - 18 y = 315

Or, 45 y = 315

Or, y = 7

From (Eq. 1),

x = 2 * 7 / 7 = 2

So, the number is 10 x + y = (10 * 2) + 7 = (20 + 7) = 27

Answer

Check:

Sum of the digits = 2 + 7 = 9

9 * 3 = 27 ✓

Adding 45 to the number 27, we get 72. So, the digits get reversed.

Answers

Answer:

R = 30

Step-by-step explanation:

Given y is directly proportional to R² then the equation relating them is

y = kR² ← k is the constant of proportion

To find k use the condition when R = 4, y = 24, then

24 = k × 4² = 16k ( divide both sides by 16 )

1.5 = k

y = 1.5R² ← equation of proportion

When y = 1350 , then

1350 = 1.5R² ( divide both sides by 1.5 )

900 = R² ( take the square root of both sides )

[tex]\sqrt{900}[/tex] = R , that is

R = 30

Tom made fruit punch for a party. He mixed 2 gallons of orange juice, 4 quarts of pineapple juice, 3 pints of cranberry juice, and 8 cups of apple juice. How many quarts did he make in all? (2 points)

Answers

Answer:

15.5 quarts

Step-by-step explanation:

1.5 +8 + 4 + 2

there is need to convert the measures that are not in quarts to quarts

1 gallon  = 4 quarts  : 2 x 4 = 8 quarts

1 cup = 0.25 quarts : 0,25 x 8 = 2 quarts

1 pint = 0.5 quarts : 0.5 x 3 = 1.5 quarts

Total quarts = 1.5 +8 + 4 + 2 = 15.5 quarts

Alex paid 108.34 for groceries. Rounded to the nearest dollar, how did alex pay for groceries?​

Answers

108.34 rounded to the nearest dollar is 108

The rounded figure of the amount Alex paid at the groceries shop is $108.

What is rounding a figure?

The process of replacing a number by another number of approximately the same value but having fewer digits is called rounding a figure.

Given that, Alex paid 108.34 for groceries. We need to round it to the nearest dollar,

We know that,

If the first decimal digit is 5 or more, we increase the whole part by one unit. For example, $34.57 rounded to the nearest whole dollar is $35.

If the first decimal digit is less than 5, we leave the whole part as it is. For example, $45.19 rounded to the nearest dollar is $45.

Here, the first decimal point is less than 5, therefore, we will leave the whole part as it is.

Hence, the rounded figure of the amount Alex paid at the groceries shop is $108.

Answer:

y = 1/2 x+4

Step-by-step explanation:

Slope intercept form is y = mx+b, where m equals the slope and b is the y-intercept.

The slope can be calculated using the formula [tex]m = \frac{y_{1}-y_{2} }{x_{1}-x_{2} }[/tex].

I'll be plugging in (2,5) and (4,6) to calculate the slope.

m = (6-5)/(4-2) = 1/2

The y-intercept is the y-coordinate of where the line meets the y-axis. In the graph, you can see that the line intersects with the y-axis at (0,4). The y-coordinate of (0,4) is 4, so therefore it is the y-intercept.

Plugin m = 1/2 and b = 4 into the slope-intercept formula (y = mx+b), and you get y = 1/2 x+4
