What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater than the numerator.
Example: 1/2, 1/3 is a fraction.
We have,
On Saturday:
The number of hours Kiana studied = 2 ¼ hours
This can be written as,
= 2 (1/4)
= 9/4 hours _____(A)
The number of hours studied for each subject.
= ¾ hour ______(B)
The formula for dividing fractions.
= a/b ÷ c/d
= ad/bc
Now,
From (A) and (B) we get,
The number of subjects.
= 9/4 ÷ 3/4
= (9 x 4) / (4 x 3)
= 3 subjects
Thus,
The number of subjects studied for the exam is 3 subjects

Reaserch how x ray technications use math in their careers
Answer:
X-ray technicians, also referred to as radiologic technologists, would need math skills to be able to use accurate calculations when mixing chemicals used in x-ray imaging processes. In addition to this, the critical and logical thinking abilities practiced in the study of mathematics are useful in the day to day job, especially because working with imaging technology and machines to get detailed images for physicians to view is crucial to patient care and treatment.
Education for an associate's degree in radiologic technology is going to be focused heavily on STEM related courses such as anatomy, radiation safety, imaging procedures, and pathology. For this reason, it is recommended that high school students planning on pursuing this educational path take plenty of classes in math, science, and technology.
Radiologic technology job opportunities are expected to increase by 9 percent between 2018 and 2028 according to the Bureau of Labor and Statistics. This is greater than the 5 percent average increase projected for all other jobs, which means radiological technology is a career with a strong and stable outlook.

A map represents every 18 kilometers with 1 centimeter. If two locations are actually 54 kilometers apart, how many centimeters apart are the two locations on the map?
A scale on a map is used to compare one length with another length.
The two locations on the map are 3 centimeters apart.
From the question, a map represents every 18 kilometers with 1 centimeter. Hence:
18 kilometers = 1 centimeter
54 kilometers = ?
Cross Multiply
54 kilometers x 1 centimeter / 18 kilometers
= 3 centimeters.
Therefore, the two locations on the map are 3 centimeters apart.

Mia is 7.01568 x 10^*6 minutes old. Convert her age to more appropriate units using years, months, and
days. Assume a year has 365 days and a month has 30 days.
Mia is
years=,
= months, and =
days old.
[tex]7.01568 * 10^6=7015680[/tex] minutes
There are:
60 minutes in an hour
24 hours in a day (60 * 24 = 1440 minutes)
30 days in a mouth (1440 * 30 = 43,200 minutes)
360 days in a year (1440* 365 = 525,600 minutes)
To find out how many years old she is we must divide the number of minutes old she is by the number of minutes in a year.
7015680 / 525,600 = 13 years with a remainder of 182,880 minutes
To find out how many months old she is we must divide the remaining minutes by the number of minutes in a month.
182,880 / 43,200 = 4 months with a remainder of 10,080 minutes
To find out how many days old she is we must divide the remaining minutes by the number of minutes in a day.
10,080 / 1440 = 7 days
Answer: Mia is 13 years, 4 months and 7 days old

Solve the equation: 3/8g + 2 = 5
Answer:
3/8g + 2 = 5
Subtract the number 2 from both sides of the equation.
3/8g = 3
Now divide 3/8 from both sides of the equation.
3/8 divided by 3/8 equals 0. 3 divided by 3/8 equals 8.
The final answer is:
g = 8
------------------------------------------------------------------------------------------
Check your answer:
3/8g + 2 = 5
Substitute 8 into the spot where the variable g was.
3/8 X 8 + 2 = 5
So our answer x = 8 is true.

No, she isn't
Step-by-step explanation:
(-2)² is basically -2 x -2, which we know is 4.
-2² is slightly different. In this case, you don't consider it as the square of -2, but you do the square ignoring the negative sign, and then add it at the end.
So think about it like this,
We do 2² first, and then add the minus, so it becomes -4 instead of positive 4. Does that make sense?
Answer: Incorrect
Step-by-step explanation:
Rule :
[tex](-10)^2=| -10|^2 =100 \\\\ -10^2=-(10)^2=-|10|^2=100[/tex]
Then :
