The total number of laps taken by Janice and Thomas in 1 hour is 15

<h3><u>Solution:</u></h3>

We have been given the following data, Janice and Thomas are roller blading around Sampson Pond it takes them 4 minutes to complete a lap.  

We need to write and solve an equation to how many laps they can complete in one hour if they continue roller at this pace.

We know that, 1 lap = 4mins

\text {The total number of laps }=\frac{\text { total time spent roller blading }}{\text { time taken to complete each lap }}

Plugging in values, we get

\text { Total number of laps }=\frac{1 \text { hour }}{4 \text { mins }}

We know that 1 hour = 60 minutes

=\frac{60 \mathrm{mins}}{4 \mathrm{mins}}=15

Hence, the total number of laps taken by Janice and Thomas in 1 hour is 15

janice invests a total of 8000 in two different accounts. the first account returns 5%, while the second account returns 8%. if
Zinaida [17]

Answer:

"She invested $2500 in 5% account and $5500 in 8% account"

Step-by-step explanation:

Let the amount invested in 5% account be "x"

So, the amount invested in 8% account would be "8000 - x"

Interest amount is the percentage multiplied by amount invested. So

Interest of 5% account = 5% of x = 0.05x

Interest of 8% account = 8 % of 8000 - x = 0.08(8000 - x)

Total interest is the sum of these 2 expressions that EQUATES to 565 (given). Let's solve for x:

0.05x + 0.08(8000 - x) = 565\\0.05x+640-0.08x=565\\0.03x=75\\x=2500

and thus,

"8000 - x" = 8000 - 2500 = 5500

Hence,

She invested $2500 in 5% account and $5500 in 8% account

Hi can anyone help me with this please
Nostrana [21]

Answer:35in.

Step-by-step explanation:

I reccomend splitting it into sections when given problems like this.

The smaller two rectangles would be 5in * 2in which is 10in then just add them together.

For the bigger one, you'd do 5-2 in order to get the missing inches which will be 3+2 once added 5in*3in is 15in.

Finally, add 15+10+10 (15=The middle rectangle and 10=the sides)
