Megan has $1.10 in dimes nickels and pennies she has three times as many nickels as pennies and the number of Dimes is 2 less than the number of pennies how many dimes nickels and pennies does she have

Answers

5 Pennies = 5 Cents

15 Nickels = 75 Cents (5 × 3 = 15, representing that there are three times as many Nickels as Pennies)

3 Dimes = 30 Cents (5 - 2 = 3, representing that there are 2 less Dimes than Pennies)

Total = $1:10

Larry,Mary,and Terry each had a full glass of juice.Larry drank 3/4 of his.Mary drank 3/8of hers.Terry drank 7/10 of his.who drank less than 1/2 of their juice?

Answers

Answer: Marry drank less than half of her glass of juice.

Step-by-step explanation: Given that Larry, Mary and Terry each had a full glass of juice.Larry drank $(3)/(4)$ of his. Mary drank $(3)/(8)$ of hers and Terry drank $(7)/(10)$ of his.

We are to find who drank less than $(1)/(2)$ of their juice.

We have

Portion of the glass of juice that Larry drank

$=(3)/(4)>(2)/(4)\left(=(1)/(2)\right).$

Portion of the glass of juice that Mary drank

$=(3)/(8)<(4)/(8)\left(=(1)/(2)\right).$

Portion of the glass of juice that Terry drank

$=(7)/(10)>(5)/(10)\left(=(1)/(2)\right).$

Therefore, Marry drank less than half of her glass of juice.

Mary drank the least because when half of 8 is 4/8.

PLEASE HELP ME PRE CAL/TRIG The first Ferris Wheel had a diameter of 250 feet and took 10 minutes to complete one full revolution.

a. How many degrees would the Ferris wheel rotate in 100 seconds?

b. How far has a person traveled of he or she has been on the Ferris wheel for 7 minutes?

c. How long would it take for a person to travel 200 feet?

Try to show work :))

Answers

Answer:

A) 60 Degrees

B) 550 Feet

C) 2.5 minutes

Step-by-step explanation:

a) So the wheel has completed one revolution in 10 minutes so lets first divide 100 secs with 10 minutes to calculate the the fraction of revolution

1 min = 60 secs

10 min = 600 secs

100/600 = 1/6

One complete revolution is 360 degrees and 1/6 of 360 degrees will be 60 degrees .

360/6 = 60°

b) It takes 10 minutes to complete one revolution so if the person is on it for 7 minutes it would be 7/10 of a revolution . The ferris wheel has a diameter of 250 feet so the radius will be 125 feet because it is the half of the diameter and the circumference will be 250 π . To calculate the distance lets multiple the fraction of the revolution which is 7/10 into the circumference $(7)/(10) * (250 pi)$ = 550 Feet.

C)It took 10 minutes to travel 250 π now we will use this relation to calculate 200 feet . lets suppose t is for time .

$(250pi)/(10) =(200)/(t)$ .

After solving this equation as there is only one unknown which is "t "the answer will be 2.5 minutes.

The temperature decreased from 71.5*F to 56.8*F overnight. How much did the temperature drop?

Answers

You use subtraction:
71.5*F- 56.8*F= 14.7*F
Hope this helps~

The word decreased shows that you need to use subtraction for this problem.

Take 71.5*F - 56.8*F = 14.7*F that the temperature dropped
