Robin, who is self-employed, contributes $4500/year into a Keogh account. How much will he have in the account after 30 years if

pashok25 [27]

Answer:

The amount that would be in the account after 30 years is $368,353

Step-by-step explanation:

Here, we want to calculate the amount that will be present in the account after 30 years if the interest is compounded yearly

We proceed to use the formula below;

A = [P(1 + r)^t-1]/r

From the question;

P is the amount deposited yearly which is $4,500

r is the interest rate = 2.5% = 2.5/100 = 0.025

t is the number of years which is 30

Substituting these values into the equation, we have;

A = [4500(1 + 0.025)^30-1]/0.025

A = [4500(1.025)^29]/0.025

A = 368,353.3309607034

To the nearest whole dollars, this is;

$368,353

Answer:

70%

Step-by-step explanation:

$42\div60$

Calculate

$\frac{42}{60}$

Cross out the common factor

$\frac{7}{10}$

Multiply a number to both the numerator and the denominator

$\frac{7}{10}\times\frac{10}{10}$

Write as a single fraction

$\frac{7\times10}{10\times10}$

Calculate the product or quotient

$\frac{70}{10\times10}$

Calculate the product or quotient

$\frac{70}{100}$

Rewrite a fraction with denominator equals 100 to a percentage

$70$ %

Find the slope of the line that passes through each pair of points (13,-3),(-5,-5)

PIT_PIT [208]

Answer:

$\boxed{\bold{\frac{1}{9} }}$

Explanation:

(13,-3), (-5,-5)

Find The Slope:

$\bold{\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}}$

$\bold{\left(x_1,\:y_1\right)=\left(13,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-5,\:-5\right)}$

$\bold{m=\frac{-5-\left(-3\right)}{-5-13}}$

$\bold{ \ m \ = \ \frac{1}{9} }$
