Answer:
The first step when multiplying fractions is to multiply the two numerators. The second step is to multiply the two denominators. Finally, simplify the new fractions. The fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator.
Last year, the Midas Middle School cafeteria served pizza on 12% of the school days. If there were 175 school days, how many times was pizza served?
Answer:
21
Step-by-step explanation:
This is extremely hard to do on paper so I used a calculator but this is my explanation. So 12% = .12 so the decimal way is 175 x .12 = 21. Pizza was 21 times.
Answer:
Pizza was served on 21 days.
Step-by-step explanation:
12% of 175 days comes out to 21 days.
Pizza was served on 21 days.
Erwin Elementary decided to plant a garden. They set up a rectangle that was
20.75 meters by 15.8 meters. What is the perimeter of the garden? *
Answer:
P = 73.1 m
Step-by-step explanation:
The length of a rectangle, l = 20.75 m
The width of a rectangle, b = 15.8 m
We need to find the perimeter of the garden. The formula for the perimeter of a rectangle is given by :
P = 2(l+b)
Substitue all the values,
P = 2(20.75+15.8)
P = 2(36.55)
P = 73.1 m
So, the perimeter of the garden is 73.1 m.

A rectangular prism is 3 ft long 4 ft wide and 2 ft tall. What is the length of the longest diagonal?
Answer: Pythagorean Theorem in 3 D
sqrt ( 3^2 + 4^2 + 2^2) =
sqrt ( 9 + 16 + 4) =
sqrt( 29) = 5.3852 approximately
Step-by-step explanation:
The longest diagonal is about 8.9 inches. The longest length is going to be between the two longest lengths, the width and the height. The Pythagorean theorem is a^2 + b^2 = c^2. Plug the width and height into a and b of the Pythagorean equation. (4)^2 + (8)^2 = c^2. Now simplify the equation. 16 + 64 = c^2. 80 = c^2. Now find the square root of each side. (sqrt)80 = (sqrt)c^2. If you simplify this, you will find that c is equal to about 8.9 inches.
Brianna's parents earned $43,329 for the year. During the year they paid $9,966 in taxes. At the end of the year when taxes are calculated, they calculate that they need to pay $11,660 in total taxes. How much more will they need to pay?

Amy rolls a number cube ten times and gets 3 four times! If she rolls the number cube 240 times, how many times should she get a 3 (Hint: Should her results be used, or the theoretical probability?).
Answer:
Amy should not use her previous luck of rolling a 3 four times because theoretical probability remains the same even after an event favoring one side has occurred by chance.
Step-by-step explanation:
Assuming that this number cube has 6 sides, there is only 1 side that has a 3 on it. For this reason, every time the cube is rolled there is a 1 in 6 chance that the number will be a 3. If she rolls the number cube 240 times, 1 out of 6 rolls would be a 3. This means that 240/6 equals the number of times she would get a 3. Moreover, Amy would role the number 3 on 40 different times after rolling the cube for a total of 240.

A spinner is divided into 9 equal parts, numbered 1-9. You spin the spinner 15 times
and even numbers come up six times. What is the difference between the experimental
probability of spinning an even number and the theoretical probability of spinning an
even number?
Experimental probability:
Theoretical probability:
Answer:
5/9
Step-by-step explanation:
Experimental was what actually happened.
Theoretical was what should happen in a perfect, equal world.
E: 6/6 = 1

please find x for me :)
Answer:
85
Step-by-step explanation:
as the lines are parallel, the 95 angle is the same as the angle below x.
So to find x you take 95 from 180 because angles on a straight line add up to 180.
therefore x = 85

Solve for w,
thanks!
w = 12
to solve this, you have to multiply both sides by 2 to cancel out the two on the left. you’ll be left with -7w = 84. then, you divide both sides by -7 to isolate the variable, which is w. you’ll end up with w=12.

what is 75:___= 25:8
Answer:
24
Step-by-step explanation:
75/3 is equal to 25... So, in theory, if you multiply 8 by 3, you should get 24. To check that: 75/24 = 25/8
Answer:
24
Step-by-step explanation:
Considering that 25 can go into 75 by being multiplied by 3, you'd multiply 8 by 3 to get your answer.

(9,1 ) is the solution of 64(x-8)²+ 12y² < 144 inequality.
What is solution for inequality?A solution for an inequality in x and y are numbers such that when we substitute that number for x and y we have a true statement.
We substitute x = 9 and y = 1 in each inequality. The inequality, for which the values satisfy, has (9, 1) as the solution.
1.
x² - y² > 84
81 - 1 > 84
80 > 84
not true.
2.
x >= 3(y+2)² - 2
9 >= 3(3)² - 2
9 >= 27 - 2
9 >= 25
not true.
3.
4(x-4)² - 16(y+1)² > 36
4(5)² - 16(2)² > 36
100 - 64 > 36
36 > 36
not true.
4.
64(x-8)² + 12y² < 144
64 + 12 < 144
76 < 144
True.
Hence, 64(x-8)²+ 12y² < 144 has the solution (9, 1).

Answer:
So, /(100÷2) = 117/50 when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 234/100 is also equal to 2 17/50 when expressed as a mixed number.
