What would you divide the numerator and denominator by to put 16/24 in simplest form?
Answer:
8
Step-by-step explanation:
if you divide the numerator by 8 you get 2 and divide the denominator by 8 and you get 3
the simplest form would be 2/3 which was divided by 8
Answer:
Divide both numerator and denominator by 8.
Step-by-step explanation:
Firstly, find the greatest common factor (GCF) of both values.
16: 1, 2, 4, 8, 16
24: 1, 2, 3, 4, 6, 8, 12, 24
The GCF of both values is 8.
Now divide, [tex]\frac{16}{24}[/tex] ÷ [tex]\frac{8}{8}[/tex] to get the final value of [tex]\frac{2}{3}[/tex].
Simplest value is 2/3.

What is (4/9)^2?
What is 4 over 9(as a fraction) to the power of 2?
Answer:
16/81
Step-by-step explanation:
To square a fraction, you would have to square both the denominator and the numerator. You would have to do 4x4/9x9, which is 16/81.
Answer:
The answer is 16/81
Step-by-step explanation:
To evaluate this equation first find a understanding of what needs to be solved.
Here we see that we need to solve 4/9th to the power of 2.
to solve this we find what 4 to the power of 2 is and what 9 to the power of 2 is.
To use the power of 2 you multiply the number to itself that many times so if its 5 to the power of 3 you would right it as 5 x 5 x 5.
In this case we need to do 4 x 4 and 9 x 9.
4 x 4 = 16
9 x 9 = 81
The 4 x 4 solution remains as the numerator
The 9 x 9 solution remains as the denominator
After solving we get 16/81, due to the 81 not being even and 16 not being a multiple we can not simplify this fraction anymore.
The correct answer is 16/81 have a great day :)

A summer camp cookout is planned for the campers and their families. There is room for 200 people. Each adult costs $4, and each camper costs $3. There is a maximum budget of $750. Write the system of inequalities to represent this real-world scenario, where x is the number of adults and y is the number of campers. x + y ≤ 200 4x + 3y ≤ 750 x + y ≤ 750 4x + 3y ≤ 200 x + y ≤ 200 3x + 4y ≤ 750 x + y ≤ 750 3x + 4y ≤ 200
Answer:
I think its A
Step-by-step explanation:
The required system of inequalities is x + y ≤ 200 and 4x + 3y ≤ 750. Hence, the first option is the correct choice.
What is inequality?Inequality is a non-equal relation between two expressions involving variables and constants.
The sign of the inequality can be, less than (<), greater than (>), less than or equal to (≤), or greater than or equal to (≥).
How to solve the question?In the question, we are asked to write the system of inequalities to represent the given scenario, where x is the number of adults and y is the number of campers.
We are informed that there is a room for 200 people.
Thus, the total number of people, that is, the number of adults + the number of campers, or, x + y should be less than or equal to 200.
This gives us an inequality:
x + y ≤ 200.
We are informed that the cost of an adult is $4 and the cost for a camper is $3, and the total budget is $750.
Thus, the total cost, that is, the cost of all adults + the cost of all campers, or, 4x + 3y should be less than or equal to 750.
This gives us an inequality:
4x + 3y ≤ 750.
Thus, the required system of inequalities is x + y ≤ 200 and 4x + 3y ≤ 750. Hence, the first option is the correct choice.

After sales tax, A $96 watch costs $101.28. what is the sales tax percentage?
Answer:
i think it's 5.5 percent
Answer: The answer is 5.5% sales tax percentage
Step-by-step explanation:
First, subtract the total amount by the original amount
$101.28-$96= 5.28
Next, you would divide 5.28 by 96
5.28/96 = 0.055
The final part in which to get the answer is to multiply 0.055 with 100%
0.05·100= 5.5%

The mass of 1 L of water is 1 kg. The mass of gasoline is 0.68 times the mass of water. What is the mass of the gasoline in a full tank that holds 75 L.
Hence, the mass of the gasoline in a full tank that holds [tex]75L[/tex] is [tex]680[/tex]grams.
What is the mass?
Mass refers to the quantity of matter in an object. Mass is generally measured by how much something weighs. The more matter something has, the more it will weigh.
Here given that,
The mass of [tex]1[/tex] L of water is [tex]1[/tex] kg. The mass of gasoline is [tex]0.68[/tex] times the mass of water.
As we know,
[tex]1L=1000ml[/tex]
So, [tex]0.68[/tex]×[tex]1000=680grams[/tex]
As per this the mass of water is greater than the mass of gasoline.
Hence, the mass of the gasoline in a full tank that holds [tex]75L[/tex] is [tex]680[/tex]grams.

ΔABC is an isosceles triangle with AB = AC, D is the midpoint of BC and
AD is joined. Prove that ΔABD ≅ ΔACD.
I kinda have a problem with triangles and congruency....little help please ?
Step-by-step explanation:
Okay, so the triangle would look something like this:
see the image attached
Since AB=AC, which is given; <ABD = <ACD, because they are the angles opposite from the congruent sides of the isosceles triangle; and <ADB=<ADC, as AD is the bisector*; ΔABD ≅ ΔACD using SAA/AAS (side-angle-angle) congruencey.
*If the bisector of an angle in a triangle meets the opposite side at its midpoint, then the triangle is isosceles, and vice versa

Regina is buying a new car. She sees two advertisements in the paper for the same car at two different prices from two different dealerships. Both dealers are offering a simple-interest loan for the price of the car.
A photo of car includes two ads. Ad A shows the vehicle priced at twenty-four thousand two hundred dollars at six point five percent interest and an unknown number of years. Ad B shows an unknown price, at a five point three percent interest over nine years.
Part A
Regina calculates that to buy the car in Ad A, the loan would ultimately cost her $41,503. Over how many years is the loan in Ad A to be paid back?
Part B
Regina calculates that to buy the car in Ad B, the loan would ultimately cost her $38,402. What is the price of the car offered in Ad B?
Part C

Answer: Answer is -11.95
You can give the unknown value as x to make things easier
( x + 1.75 ) / 2 = -5.1
Find the value of x:
x + 1.75 = –5.1 x 2
x + 1.75 = -10.2
x = -10.2 – 1.75
