The trick Is to break it up 2 hours and 20 minutes and convert the 20 minute into hours, so if he runs at 6km/h then in 2 hours he ran 12 kms and 20 minutes in hours = 1/3 of hour therefore 6 multiplied by 1/3 is 2 km therefore th total he ran was 14 kms

4. James and Terry open a savings account that has a 2.75% annual interest rate, compounded monthly. They
Zinaida [17]

$ 159,744.59 will be in the account after 20 years.

Answer: Option A

<u>Step-by-step explanation:</u>

Need to find out the amount present in the account after 20 years. The formula to find out the future value is,

          \text {Future value}=p \times\left(\frac{\left(1+\frac{r}{n}\right)^{n t}-1}{\frac{r}{n}}\right)

Here  

p : amount deposit monthly =$500

r : rate of interest  = \frac{2.75}{100} = 0.0275

n : 12(compound monthly)

t : time =20

By substituting all the given datas in the above equation, we get

    \text { Future value }=500 \times\left(\frac{\left(1+\frac{0.0275}{12}\right)^{240}-1}{\frac{0.0275}{12}}\right)

    \text {Future value}=500 \times\left(\frac{(1+0.002291)^{240}-1}{0.002291}\right)=500 \times\left(\frac{(1.732)-1}{0.002291}\right)

   \text { Future value }=500 \times\left(\frac{0.732}{0.002291}\right)=500 \times 319.511=\$ 159,744.99

The average of Johnny's two test grades is a 92 what must he get on his 3rd test to raise his average to a 94?
jeka57 [31]

Answer:

Johnny needs to score 98 on third test to raise average to 94

Step-by-step explanation:

Given that average of two tests is 92.

The score of next test has to be found that means there will be a total of 3 tests.

The average will be:

Avg = \frac{test1+test2+test3}{3}

It is also given that he has to raise his average to 98

We have to use the average formula for finding the third value

So,

94 = \frac{92+92+test3}{3}\\94*3 = 184+test3\\282  = 184+test3\\test3 = 282-184\\test3 = 98

Hence,

Johnny needs to score 98 on third test to raise average to 94
