This weekend, they plan to ride a bicycle with a total mileage of 3 3/4. If they travel 2 1/4 miles and take a break, how many miles will they need to travel?

Answers

Answer:

1 1/2 miles

Step-by-step explanation:

Total mileage needed = 3 3/4 mies

Amount taken = 2 1/4 miles

Amount they still need to travel = Total-amoutnt taken.

Amount they need to travel = 3 3/4 - 2/1/4

Convert to improper fractions

Amount they need to travel = 15/4-9/4

Amount they need to travel= 6/4

Amount they need to travel = 1 2/4

Amount they need to travel= 1 1/2 miles

It takes 43 facial muscles to frown. This is 26 more muscles than it takes to smile. Write and solve an equation to find the number of muscles it takes to smile. (example: s + 1 = 4)

Answers

Answer:

Number of facial muscles it takes to smile, S = 20

Step-by-step explanation:

Let

Number of facial muscles it takes to smile = S

Number of facial muscles it takes to frown, F = 46

This is 26 more muscles than it takes to smile

F = S + 26

46 = S + 26

Subtract 26 from both sides

46 - 26 = S + 26 - 26

20 = S

S = 20

The number of muscles it takes to smile is 20

A standard showerhead in Marty's house dispenses 7 gallons of water per minute. Marty changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead. y = 3x How much water does Marty save each day with the change in showerheads if he uses the shower for 8 minutes each day? 4 gallons 12 gallons 32 gallons 53 gallons

Answers

Answer:

32 gallons

Step-by-step explanation:

A standard showerhead in Marty's house dispenses 7 gallons of water per minute. If he showers for 8 minutes, he uses:

1 minute = 7 gallons

8 minutes = x

x = 7 × 8 minutes = 56 gallons of water

We are told that:

Marty changed this showerhead to an energy-saving one. The equation shows the amount of water dispensed, y, as a function of the number of minutes, x, for the new showerhead. y = 3x

The equation for the energy saving shower:

y = 3x

Where x is the number of minutes spent in the shower

For 8 minutes

y = 3 × 8

y = 24 gallons

The gallons of water Marty saved each day with the change in showerheads if he uses the shower for 8 minutes each day is calculated as:

56 gallons - 24 gallons

= 32 gallons

Caleb read a total of 30 pager over 2 hours. After a total of 3 hours of reading this week, how many pages will Caleb have read in all? Solve using unit rates

Answers

Answer:

45 pages

Step-by-step explanation:

Caleb read a total of 30 pager over 2 hours.

To find the unit rates

2 hours of reading = 30 pages

1 hour of reading = x

Cross Multiply

2× x = 30 × 1

2x = 30

x = 30/1

x = 15 Pages.

Hence, he read 15 pages per hour

After a total of 3 hours of reading this week, how many pages will Caleb have read in all?

If;

1 hour = 15 pages

3 hours = x pages

Cross Multiply

x = 3 × 15 pages

x = 45 pages

Hence, Caleb would have read 45 pages in all

1/8 of the lawn in 1/4 of an hour. That mean you would need a whole hour to do 4/8 or 1/2 of the lawn. So you would need two hours to do the whole lawn.
C-2 hours because if you multiply 1x4=4 1x8=8 and then you simplify by 4 and you got 2/1
