7. You have $367.50 after two years.

Start by converting 2.5% into a decimal (divide by 100) and multiplying by 350 to find the rate of interest per year.

350(0.025) = 8.75

Since it's for two years, multiply by two.

8.75 x 2 = 17.5.

Add it on to he original, and we have

350 + 17.5 = 367. 5, or $367.50 when converted back to money.

8. The annual interest rate is 2.4%

find the interest rate per year:

120/2.5 = 48 dollars per year. this is the interest amount, we want to find the interest rate. To do this, find what % of 2000 that 48 is equal to.

Set up a system of equations and cross multiply.

$\frac{48}{2000} = \frac{x}{100}$

2000x = 48(100) > 2000x = 4800

2000/2000x = 4800/2000 > x = 2.4

So, the interest rate is 2.4%.

9. the interest paid is $300 after six months, and $600 after a year.

Find the interest rate, similar to problem 7.

3000 x 0.2 = 600. This means the interest paid is $600 a year. In six months, the total will be half, or $300.

10. four years.

Find interest rate.

200(0.035) = $7/year

Remember that value. Subtract needed from current.

228 - 200 = $28.

So, we have an interest rate of $7 a year and we need $28. Normally, we'd solve using an expression, but in this case we can use simple multiplication. Knowing that 7 x 4 = 28, We can decide that it will take four years.

A nursery sells plants in flats. There are 6 plants in each tray. Each flat has six trays. The nursery sold 18 flats on Saturday

marshall27 [118]

For this case we have to:

There are 6 plants per tray.

There are 6 trays for each flat, so for each flat there are $6 * 6 = 36$ plants.

Saturday day: $18 flat * 36 plants = 648$

Thus, on Saturday they sold 648 plants.

Sunday: $21 flat * 36plants = 756$

Thus, on Saturday they sold 756 plants.

Thus, in total $648 +756 = 1404$ plants were sold.

Answer:

$648 +756 = 1404$ plants were sold.

blsea [12.9K]

Answer:

5.8496 min

Step-by-step explanation:

$\displaystyle t=\frac{10}{\ln{2}}\int_{220}^{280}{\frac{1}{T-100}}\,dT=\frac{10(\ln{(280-100)}-\ln{(220-100)})}{\ln{2}}=\frac{10\ln{(3/2)}}{\ln{2}}\\\\\boxed{t\approx5.8496\quad\text{min}}$

Modern calculators can perform integration with high accuracy. This one gives the same result.
