Which value is a perfect square? 12 24 49 63
Answer: 49 is a perfect square.
Step-by-step explanation: We say that 49 is a perfect square because it is the product of an integer multiplied by itself, 7×7. If we had a square with an area of 50, this wouldn't be a perfect square because no integer, multiplied by itself, will give a product of 50.
Gregory watches TV for an average of 90 minutes per day on weekdays and an average of 135 minutes per day on the weekends. What is the ratio of the average number of minutes he watches TV on weekdays to minutes he watches TV on weekends?
Answer: 2:3
Step-by-step explanation:
minutes per day on weekdays:minutes per day on weekends
90:135
It can be written in simplier form, because both numbers can be divided by 45
90÷2=45 and 135÷45=3
The ratio is 2:3.

Mateo has been studying after school while preparing for a test retake. His work paid off ! His score on the retake was a 94. This was quite a difference from the grade on his first attempt which was a 68. What is the approximate percent of change between the two tests?
Answer:
28%
Step-by-step explanation:
We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.
First, subtract the two numbers
94 - 68 = 26
Put 26 over 94 to make this 26/94
Divide to get 0.28 (simplified and rounded)
So the increase was 28%
Answer:
increase of 28?
Step-by-step explanation:
Okay so, I believe it is 28, let me explain. First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100. If the answer is a negative number, this is a percentage increase.

Answer:
x = 64/5
Step-by-step explanation:
34x+85=3(13x+7)
Step 1: Simplify both sides of the equation.
34x+85=3(13x+7)
34x+85=(3)(13x)+(3)(7)(Distribute)
34x+85=39x+21
Step 2: Subtract 39x from both sides.
34x+85−39x=39x+21−39x
−5x+85=21
Step 3: Subtract 85 from both sides.
−5x+85−85=21−85
−5x=−64
Step 4: Divide both sides by -5.
−5x/−5=−64/−5
x=64/5

The fuel tank of a cruise ship holds 28,665 barrels of gasoline. A fuel tank hold 5,312 barrels of gasoline. Can 5 fuel tankers fuel fill the cruise ship's tank?
Answer:
No
Step-by-step explanation:
Given that :
Fuel tank of cruise ship hold 28,665 barrels
Capacity of fuel tanker = 5312 barrels
Can 5 fuel tankers fuel fill the cruise ship's tank?
5 * capacity of fuel tanker
5 * 5312 = 26,560 barrels
No because 28665 > 26560

Answer:
The simplest form of [tex]\frac{14a^2}{24a}[/tex] is [tex]\mathbf{\frac{7a}{12}}[/tex]
Step-by-step explanation:
We need to write [tex]\frac{14a^2}{24a}[/tex] in simplest form.
We know the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]
Applying the rule:
[tex]\frac{14a^2}{24a} \\=\frac{14a^{2-1}}{24}\\Since \ 14 \ and \ 24 \ are \ divisible\ by \ 2 \\=\frac{7a^1}{12} \\=\frac{7a}{12}[/tex]
The simplest form of [tex]\frac{14a^2}{24a}[/tex] is [tex]\mathbf{\frac{7a}{12}}[/tex]

They spent 2 hours and 25 minutes in Central Park and 1 hour and 20 minutes in Times Square before dinner. What time was it when Ling and her family went to dinner?
We add the total number of hours together
1 hour 50 minutes + 2 hours 25 minutes + 1 hour 20 minutes
= 4 hours 95 minutes
= 5 hours 15 minutes
5 hours 15 minutes + 2.35 pm

On Saturday, Carrie went to the store and bought 4 loaves of bread and 1 gallon of milk for a total of $12.50. The next weekend, she went to the same store and spent $11.50 on 2 loaves of bread and 2 gallons of milk. The prices had not changed. What is the price for one gallon of milk?
Answer:
The price of one gallon of milk is $3.5
Step-by-step explanation:
x----> the price of one loaves of bread
y----> the price of one gallon of milk
we know that
4x+y=12.50 ----> equation A
2x+2y=11.50 ----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2.25,3.5)
see the attached figure
therefore
The price of one loaves of bread is $2.25
The price of one gallon of milk is $3.5
