Barry wants to take out a loan from his bank for $1000 to buy a bicycle the interest rate on the loan from the bank is 9% he wants to pay the toll amount in three monthly payments what is the amount that varies with pay in interest rate loan is to be determined.
Simple interest is defined as the percentage of earnings on the lending for a period of time
Here,
Principal = 1000
Rate = 9%
Time = 3 / 12 = 0.25 years
So,
Interest = Principal × rate × time
interest = 1000 × 0.09 × 0.25
Interest = $22.5
Thus, the required interest paid by Barry is given as, $22.5.

Using compound interest, it is found that it would take 11 years for the value of the account to reach $70,900.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.Hence, the parameters are given as follows:
[tex]A(t) = 70900, P = 37000, n = 365, r = 0.057[/tex]
We have to solve for t, then:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]70900 = 37000\left(1 + \frac{0.057}{365}\right)^{365t}[/tex]
[tex]\left(1 + \frac{0.057}{365}\right)^{365t} = \frac{70900}{37000}[/tex]
[tex]\left(1 + \frac{0.057}{365}\right)^{365t} = 1.91621622[/tex]
[tex](1.00015616)^{365t} = 1.91621622[/tex]
[tex]\log{(1.00015616)^{365t}} = \log{1.91621622}[/tex]
[tex]365t\log{1.00015616} = \log{1.91621622}[/tex]
[tex]t = \frac{\log{1.91621622}}{365\log{1.00015616}}[/tex]
t = 11.41
Rounding to the nearest year, it would take 11 years for the value of the account to reach $70,900.

At Gloria’s Restaurant, the average diner tips 18% of their total bill. Carter’s bill was $66.50. How much money should Carter tip?
Answer:
$11.97
Step-by-step explanation:
If Carter were to tip that 18%, then he should give a $11.97 tip.
0.6650 x 18 = 11.97
The amount Carter should tip at the restaurant is $11.97.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, At Gloria’s Restaurant, the average diner tips 18% of their total bill.
Therefore, The amount Carter must tip should be 18% of 66.50 which can be numerically expressed as,
(18/100)×66.50.
= $11.97.
So, Carter should tip $11.97.

sum of 4?
Answer:
9 and -5
Step-by-step explanation:
9*-5=-45
9+-5=4
The pair of factors is 9 and -5.
What is a factor?
The factor of a number is another number that can divide the first number without any remainder.
Let, one of the factors is x.
Then, the other factor is = -45/x.
Given,
x + (- 45/x) = 4
⇒ x - 45/x = 4
⇒ x - 45/x - 4 = 0
⇒ x² - 45 - 4x = 0
⇒ x² - 4x - 45 = 0
⇒ x² - 9x + 5x - 45 = 0
⇒ x(x-9) + 5(x-9) = 0
⇒ (x-9) (x+5) = 0
Hence, x = 9, -5.

Find the ratios x:y:z if x:y=9:10 and y:z=5:3
Answer:
Step-by-step explanation:
Answer:
x : y : z = 9 : 10 : 6
Step-by-step explanation:
Expressing the ratio y : z = 5 : 3 in fractional form, that is
[tex]\frac{y}{z}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )
5z = 3y ( divide both sides by 5 )
z = [tex]\frac{3}{5}[/tex] y = [tex]\frac{3}{5}[/tex] × 10 = 3 × 2 = 6
Thus
