Mary lives 1 3/4 miles from school. She rode her bycycle to school and back for 5 days. Which expression shows how to estimate the number of miles she rode?


Answer 1
1 3/4=1.75
1.75*2=3.5 for a day
She rode 17.5 miles
Answer 2

The expression which represents the number of miles Mary rode in 5 days is 5*(2 + 2).

What is mixed fraction?

A fraction represented with its quotient and remainder is a mixed fraction.

What is expression?

An expression is a number, a variable, or a combination of numbers and variables and operation symbols.

According to the given question.

Distance between Mary's house and school = [tex]1\frac{3}{4} =\frac{7}{4}[/tex]

Number of days Mary rode her bicycle to school and back = 5

⇒ Distance travelled by Mary in one day = [tex]2(\frac{7}{4} )=\frac{7}{2}[/tex]

Therefore, the expression which represents the number of miles she rode in 5 days = [tex]5(\frac{7}{2} )=\frac{35}{2}=17.5 miles[/tex] ≈ 20 miles

Hence, the expression which represents the number of miles Mary rode in 5 days is [tex]5[/tex] *(2+2).

The price of Pepsi stock was $0.65 in 1981 and $27.56 in 2011. What was the average rate of change for the stock per year
from 1981 to 2011 rounded to the nearest hundredth?


0.65 at year 0 (0, 0.65)
27.56 at year 30 (30, 27.56)

slope = (27.56 - 0.65) / (30 - 0)
slope = 26.91 / 30

Change = 0.897 or almost 90 cents

Answer: 0.9

Step-by-step explanation:

Let x be the number

Determine the value of the number

x² = 81

√x² = √81

x = 9

Find the 10% of the number

Final number = rate of percentage × original number

Final number = 10% × 9

Final number = [tex]\boxed{0.9}[/tex]

Please let me know if you have any questions

use the following list to find the average or mean, the median, the mode, and the range 10, 15, 5, 8, 6, 6, 2



Mean - 7.43

Median - 6

Mode - 8

Range - 13

Step-by-step explanation:

To find the mean/average, add up all the numbers and divide the sum by the # of data points.  (ex. you have 7 numbers, so you divide the sum of the numbers by 7.)

The median of a set of data is the middle number of ascending numbers in the data.  If there was an even number of data points you would have to add the 2 middle numbers and divide by 2.

The mode is the number that appears most frequently in the data set.

To find the range, just subtract the lowest number in the data set from the greatest number.


mean= 7.4, median = 6, mode =6, range = 13

Step-by-step explanation:

mean = 10 + 15 + 5 + 8 + 6 + 6 + 2 ÷ 7

= 52 ÷ 7

= 7.4

median= 2, 5, 6, 6, 8, 10 , 15


median is the middle number from ascending order

mode = 6

mode is the number that occurs the most

range = 15 - 2


range is the different between the largest and smallest number

The profitability, P, of a popular restaurant franchise can be modeled by the function P (t) = t4 – 9t3 + 24t2 – 20t, where t is the number of months since the restaurant opened. How many months after the franchise opens will it begin to show a profit?

5 months
3 months
2 months
1 month


Replace t with the months given as choices to see which one gives a positive value as an answer.

P(1) = 1^4-9(1)^3 + 24(1)^2-20(1) = -4

P(2) = 2^4-9(2)^3+24(2)^2-20(2) = 0

P(3) = 3^4 -9(3)^3+24(3)^2-20(3) = -6

P(5) = 5^4-9(5)^3+24(5)^2-20(5) = 0

P(6) = 6^4-9(6)^3+24(6)^2-20(6) = 96

It shows a profit in month 6 so it would start showing a profit in month 5.

The answer is 5 months

Karl drove for 4 hours. For part of the trip he drove at 50 miles per hour. For the rest of the trip he drove at 100 miles per hour.

All together he drove 250 miles.

Solve this equation for h to find out how many hours he drove at 50 miles per hour.

250 = 50h + 100(4 - h)



3 hours

Step-by-step explanation:

250 = 50h + 100(4 - h)

250 = 50h + 400 - 100h

250 = -50h + 400

-150 = -50h

h = 3
