What is the measure of ∠C?
The measure of ∠C in the triangle, ΔCDE, in the given figure, is 43°.
A triangle is a geometric figure with three sides, three angles, and three vertices. The sum of all the angles of a triangle is 180°. It is one of the most elementary geometric figures.
As it is known that the sum of all angles of a triangle is 180°,
∠C + ∠D + ∠E = 180°
∠C = 180° - ∠D - ∠E
∠C = 180° - 90° - 47°
∠C = 180° - 137°
∠C = 43°
Thus, the measure of ∠C is 43°.

for a cub scout meeting, the leader bought 4 pizzas, and 1 1/2 of the pizzas contained pepperoni. the scouts ate 5/6 of the pizzas that contained pepperoni. the remaining pizza that contains pepperoni represents what fraction of the 4 pizzas that the leader bought?
Answer: Hello there!
We have 4 pizzas, and 1 and 1/2 of them have pepperoni (and 2 and 1/2 do not have pepperoni).
The scouts ate 5/6 of the pizzas that contained pepperoni, this means that they ate 5/6 of the 1 and 1/2 pizza with pepperoni (that can be written as 1 + 1/2 = 3/2)
first we could write the initial fraction of pizza with pepperoni, this is the amount of pizza with pepperoni divided by the total amount of pizza:
(3/2)/4 = 3/8
and now, because the scouts eat 5/6, there is 1/6 left.
then we have (1/6)*(3/8) = 3/48 of the 4 original pizzas, but we could simplify it a bit by dividing both denominator and numerator by 3.
3/48 = 1/16
what is the answer of (-1/4 subtracted by 1/2) divided by (negative 4/7)
Rhea arrived at the mall at 3:45 pm she spent 45 minutes having lunch and then she shopped for 55 minutes before leaving the mall. How much time disregard spend at the mall
Rhea spent 1 hour and 40 minutes at the mall.
Explanation:To find the total time Rhea spent at the mall, we need to add the time she spent having lunch and the time she spent shopping. Rhea spent 45 minutes having lunch and 55 minutes shopping, so the total time she spent at the mall is 45 minutes + 55 minutes = 100 minutes. Since there are 60 minutes in 1 hour, we can convert 100 minutes to hours by dividing by 60. 100 minutes ÷ 60 = 1 hour and 40 minutes. Therefore, Rhea spent 1 hour and 40 minutes at the mall.

What to the power of 3 equals 729
To find what number to the power of 3 equals 729, we can experiment with cubes of small numbers. We quickly identify that 9 cubed (9×9×9) equals 729, which means 9 is the correct answer.
Explanation:The question is asking to find the number that, when cubed (raised to the power of 3), is equal to 729. This operation is also referred to as finding the cube root.
Firstly, let's investigate through experimentation. We know that cubing of exponentials involves raising a number to the power of three. For instance, 2 cubed is 2×2×2, which equals 8. Now, we're looking for a number that when cubed, results in 729.
If you try to cube smaller numbers, you'll see that cubing 8 gives us 512 and cubing 9 gives us 729. The cube of 9, written as 9×9×9, indeed equals 729. Therefore, 9 to the power of 3 equals 729.
When it comes to numbers that are not as straightforward, a calculator or understanding of cubing of exponentials would be necessary. However, in this case, through simple experimentation and knowledge of cube numbers, we have found that 9 is the number sought.

The height per floor for the Burj al Arab hotel in Dubai is calculated as 17.55 feet, by dividing the total height (1053 feet) by the number of floors (60), but we lack the Aon Center's floor heights to make the comparison as per the question's request.
The student's question is regarding the comparison of floor heights between the Burj al Arab hotel and the Aon Center, a different skyscraper. We need to first calculate the average height of a single floor for each building to compare them. Since the Burj al Arab stands 1053 feet high and has 60 floors, we divide the total height by the number of floors to determine the height per floor.
Total height of Burj al Arab: 1053 feet
Number of floors in Burj al Arab: 60
Height per floor in Burj al Arab: 1053 feet / 60 floors = 17.55 feet
However, the information provided does not include the height of the Aon Center nor its floor count to compare with the Burj al Arab as requested in the question. Additional data is needed to make the comparison. Thus, we are unable to determine how much taller or shorter each floor of the Burj al Arab is compared to the Aon Center's floors with the given information.
A tank starts out with 860 gallons of liquid. A pump adds liquid to the tank at a constant rate. After 8 hours, the tank contains 1,036 gallons. How many gallons of liquid were pumped per hour?

22
176
237
Answer:
B. 22
Step-by-step explanation:
Let x represent number of gallons per hour.
We have been given that a pump adds liquid to the tank at a constant rate. The number of gallons added after 8 hours would be [tex]8x[/tex].
We are also told that the tank starts out with 860 gallons of liquid. So total amount of liquid after 8 hours would be [tex]8x+860[/tex].
The total amount of liquid in the tank after 8 hours is 1,036, so we can represent this information in an equation as:
[tex]8x+860=1,036[/tex]
[tex]8x+860-860=1,036-860[/tex]
[tex]8x=176[/tex]
[tex]\frac{8x}{8}=\frac{176}{8}[/tex]
[tex]x=22[/tex]
Therefore, 22 gallons of liquid were pumped per hour.

4 1/2 divided by 2 3/8
The fraction we get after dividing [tex]4\frac{1}{2}[/tex] by [tex]2\frac{3}{8}[/tex] = 36/19.
Here we have to divide,
[tex]4\frac{1}{2}[/tex] by [tex]2\frac{3}{8}[/tex]
Now we can write it into simple fraction we get,
[tex]4\frac{1}{2}[/tex] = 9/2
[tex]2\frac{3}{8}[/tex] = 19/8
Since we know that,
Dividing two fractions is equivalent to multiplying the first fraction by its reciprocal. The first step in splitting fractions is to get the reciprocal of the second fraction (reverse the numerator and denominator). Then, multiply the numerators.
Therefore,
9/2 ÷ 19/8 = 9/2 x 8/19
= (9x4)/19
= 36/19
Hence,
[tex]4\frac{1}{2}[/tex] by [tex]2\frac{3}{8}[/tex] = 36/19

Show 2 ways that 6 people can share an 8-segment chewy fruit worm
Final answer:
Two ways to share an 8-segment chewy fruit worm among six people include equal division with some cutting involved for the leftover pieces, or using a trading system based on individual preferences.
Explanation:
There are multiple ways that 6 people can share an 8-segment chewy fruit worm, but let's consider two simple methods. First, we can look at equal division where each person would get 1 segment, and 2 segments are left over. These could then be halved, with six of the people receiving an extra half-segment each, ensuring everyone gets an equal share.
Another method would involve the ideas of trade and preference. Assume each person has different preferences for segments of the worm, similar to the trading scenario of the siblings with Snickers and Milky Ways. Here, they can negotiate and exchange segments based on their tastes, potentially leaving some with more segments but satisfying everyone's preference. This method requires cooperation and may result in an unequal distribution but can lead to each person being happy with their share.
