Sandy can jog 3 2/5 miles in 5/6 hour. Find her average speed in miles per hour.

Answers

Answer 1
3 2/5 = 17/5 

(17/5 mi)/(5/6 hr) = 102/25 mi/hr
Answer 2

Answer:

[tex]4\frac{2}{25}[/tex] miles per hour

Step-by-step explanation:

Sandy can jog a distance  [tex]3\frac{2}{5}[/tex] miles or  [tex]\frac{17}{5}[/tex]  in the duration =  [tex]\frac{5}{6}[/tex] hours

Since speed =  [tex]\frac{distance}{time}[/tex]

We plug in the values of distance and time in the formula of speed.

Speed = [tex]\frac{\frac{17}{5}}{\frac{5}{6}}[/tex]

           =  [tex]\frac{17}{5}[/tex] ×  [tex]\frac{6}{5}[/tex]

           =  [tex]\frac{102}{25}[/tex]

           =  [tex]4\frac{2}{25}[/tex] miles per hour

Her average speed is  [tex]4\frac{2}{25}[/tex] miles per hour.

The currency in Argentina is the Peso. The exchange rate is approximately $3 = 1 Peso. At this rate, how many Pesos would you get if you exchanged $121.10?

Answers

3dollars/1=121.10dollars/x
3x=121.10
x=40.67

The answer is 40.67 dollars

Hope this helps
Final answer:

The Pesos you would get if you exchanged $121.10 using an exchange rate of $3 = 1 Peso, you can set up a proportion and solve for x.

Explanation:

To calculate how many Pesos you would get if you exchanged $121.10 at an exchange rate of $3 = 1 Peso, you can set up a proportion:

$3 / 1 Peso = $121.10 / x Pesos

Cross multiply to solve for x:

$3 * x = $121.10 * 1

x = $363.30

Therefore, you would get 363.30 Pesos if you exchanged $121.10 at the given exchange rate.

Find the take-home percent of the gross pay: net pay $453.10, gross pay$734

50%

16%

162%

62%

Answers

453.10/734 = .617% * 100 = 61.7% --> 62%

D. 62%

Answer:

Option D. 62%

Step-by-step explanation:

Net pay = $453.10

Gross pay = $734.00

We have to find the take-home percent of the gross pay.

We will divide net pay by gross pay and multiply by 100.

Percent of the gross pay =  [tex]\frac{453.10}{734}\times 100[/tex]

                                         = 0.617302452 × 100

                                         = 61.73 ≈ 62%

The take-home percent of the gross pay would be 62%.

Me. Driscoll has 9 reports to grade. There are 6 page for each report. He grades 12 pages. How many pages does he still have to grade?

Answers

so easy

so driscoll has 9 reports to grade and each page has 6 pages.

just multiply 9 and 6 which gives you your answer 54.

so out of 54, he has graded only 12 pages which means that you need to subtract.

[tex]54-12=42[/tex]

driscoll has 42 pages left to grade.

you can recheck your answer by adding 42 ans 12 which gives your answer as 54. so yup our answer is right.
