Answer:
No, you don't.
Step-by-step explanation:
The denominator only changes if you're multiplying/dividing. You may need to create an equivalent fraction to add the fractions together, but you don't add or subtract the denominator.
Hope this helps! Have a great day!
Answer:
No, you adjust the numerator and denominator to a common denominator, then do the addition/subtraction operations with with the numerator, and finally reduce it to the lowest fraction.
Example:
1/3 + 3/4 = ?
change to a common denominator (12 works for 3 and 4)
4/12 + 9/12 = ?
add the 9 and 12
4/12 + 9/12 = 13/12
reduce to lowest form
12/12 = 1 1/12

Answer: 4 hours
Step-by-step explanation:
The water level changes at an average rate of 3 meters per hour.
The question wants to know how long it will take for the ocean water level to change 12 meters.
You can use direct proportion:
1 hour : 3 meters
x hours : 12 meters
Cross multiply to get:
3x = 12
x = 12 / 3
= 4 hours

After a 40% discount, the cost of a sofa is $471.00. What was the original cost of the sofa? NEED HELP ASAP
Answer: $659.40
Step-by-step explanation: You start with 471.00 X 0.4 which equals $188.40. So then you add $471.00 and $188.40 and you get $659.40!
The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
80% = $471
100% = $588.75
The original cost of the sofa is $588.75
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying it by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
We have,
Original cost in percentage = 100% ____(1)
Cost after 40% discount = $471
This can be written as,
80% = $471 _____(2)
From (1) and (2) we get,
80% = 471
Multiply 100/80 on both sides,
100/80 x 80% = 100/80 x 471
100% = $588.75
Thus,
80% = $471
100% = $588.75
The original cost of the sofa is $588.75

A circular running track is 14 of a mile long. Elena runs on this track, completing each lap in 116 of an hour. What is Elena’s running speed? Include the unit of measure
Answer:
The wording is quite confusing, but here it goes
Step-by-step explanation:
T(track)= 14 of a mile. 1 mile is 5280 feet. If Elena is running each lap at 116 of an hour, (116%?) then 16% of 60 is 9.6 minutes, so each lap takes 69.6 minutes. One lap is 1312 feet, so 5280/1312= 4.02, so she can run 4 laps, which will take her 278 minutes. So 1312 is 24% of a mile, and she is running at .24 mph.

Step-by-step explanation:
he spent $13 in total and bought one hot dog for $2.50 and 3 hamburgers but we don't know the price of one hamburger so we could represent it by the equaton,
2.50 + 3h = 13 now solve for x
-2.50 2.50
3h = 10.50
h=3.50
check:
2.50+3(3.50)=13
2.50+10.50=13
13=13

l=$45, P=$600, t=2 years What is the annual interest rate?
Answer:
The interest rate required to accumulate simple interest of $ 45.00 from a principal of $600.00 over 2 years is 3.75% per year.
Step-by-step explanation:
Given
l = $45
P = $600
t = 2 years
To determine
What is the annual interest rate = r = ?
Using the Simple Interest Formula
I = Prt
r = I/Pt
substituting l = 45, P = 600 and t = 2 years
r = 45 / ( 600 × 2 )
= 0.0375
converting r decimal to a percentage = 0.0375 * 100 = 3.75% per year
Thus, the interest rate required to accumulate simple interest of $ 45.00 from a principal of $600.00 over 2 years is 3.75% per year.

Inga and Aileen are measuring the temperature of frozen hydrogen. Inga is using a thermometer that has increments of 0.25∘F, and she gets a measurement of 3.25∘F. Aileen is using a thermometer that has increments of 0.125∘F, and she gets a measurement of 3.375∘F.
Which thermometer has less uncertainty?
1. Aileen's thermometer, because it has smaller increments.
2. Neither, because the uncertainty in both thermometers is the same.
3. Inga's thermometer, because 3.25∘F is less than 3.375∘F.
4. Neither, because Inga and Aileen had different measurements.
Answer: AILEEN’S THERMOMETER, BECAUSE IT HAS SMALLER INCREMENTS
Step-by-step explanation:
I did the test and the attachment below is a screenshot of my test and I got 100%
Aileen's thermometer has less uncertainty because it has smaller increments. Option A is correct.
Given that,
Inga and Aileen are measuring the temperature of frozen hydrogen. Inga is using a thermometer that has increments of 0.25∘F, and she gets a measurement of 3.25∘F. Aileen is using a thermometer that has increments of 0.125∘F, and she gets a measurement of 3.375∘F.
All over the world, most things are in use as of common quantity, so people all over the world agree that they have to follow a common system of measurement and that the common system of measurement is called standard measurement.
Here,
Aileen's thermometer has a smaller increment than Inga's thermometer,
Because of the smaller increments, it has more chances to give precise measurements and less uncertainty.
Thus, Aileen's thermometer has less uncertainty because it has smaller increments. Option A is correct.
