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°.

A. Write and inequality to answer this question
B. Solve the inequality
The inequality represent the given situation is 200-15d<80.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, a scrapyard had 200 tons of recycled steel.
They sold 15 tons per day for several days.
Let the number of days be d.
Here, the inequality is 200-15d<80
Add 15d on both the sides of an inequality, we get
200-15d+15d<80+15d
200<80+15d
Subtract 80 on both the sides of an inequality, we get
120<15d
Divide 15 on both the sides of an inequality, we get
d>8
Therefore, the inequality represent the given situation is 200-15d<80.

The area of a square living room is 256 ft2256 ft2. Which is the length of the room?
The length of the square living room is 16 feet.
To find the length of the square living room, we need to calculate the square root of the area.
Given:
Area of the square living room = 256 ft²
Let's denote the length of one side of the square as "s".
The formula for the area of a square is:
Area = side length x side length
256 = s x s
256 = s²
To find the length of the room (s), we take the square root of 256:
s = √256
s = 16
Therefore, the length of the square living room is 16 feet.
The probable question may be:
The area of a square living room is 256 ft^2. Which is the length of the room?

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.

cole had 3/4 hour of free time before dinner.He spent 2/3 of the time playing the guitar.How lonb did he play the guitar
Cole have 45 minutes of free time and he play the guitar for 30 minutes. That is 2/3 of free time.
How to find time ?Because the number of minutes in an hour is fixed at 60, you can divide any number of minutes by 60 to get a fraction of an hour. For example, 10 minutes equals 10/60 = 1/6 hour, and 24 minutes equals 24/60 = 6/15 hour.
For example, 375 minutes divided by 60 equals 6.25 hours. Multiply that fraction of an hour by 60 to get it back to minutes. In this case,. 25 x 60 = 15, implying that 375 minutes equals 6 hours and 15 minutes.
Although numbers such as 1/6 and 6/15 of an hour are accurate, they are not always easy to compare to other time measurements.
1 hour = 60 minutes meaning 1 whole,
3/4 of an hour = 45 minutes
so 2/3 of 45 minutes = 30 minutes
15+15+15= 45
so 15 + 15 = 30 minutes
He play the guitar for 30 minutes

one cabinet measures 3 feet by 2.5 feet by 5 feet. a second measures 4 feet by 3.5 feet by 4.5 which volume is greater explain
The second cabinet has a greater volume of 63 cubic feet compared to the first cabinet's volume of 37.5 cubic feet.
To compare the volume of the two cabinets, we will calculate the volume for each by multiplying the length, width, and height.
For the first cabinet, the volume is 3 feet x 2.5 feet x 5 feet, which is 37.5 cubic feet.
3 feet x 2.5 feet x 5 feet = 37.5 cubic feet
The second cabinet has a volume of 4 feet x 3.5 feet x 4.5 feet, which equals 63 cubic feet.
4 feet x 3.5 feet x 4.5 feet = 63 cubic feet
Therefore, the second cabinet has a greater volume than the first.
If your pencil is 20 cm long how many millimeters is it
To convert a pencil length of 20 centimeters to millimeters, multiply by 10, resulting in 200 millimeters.
If your pencil is 20 cm long, to convert this measurement to millimeters, you simply need to use the conversion factor that there are 10 millimeters in 1 centimeter. So, you multiply the length in centimeters by 10 to get the length in millimeters.
20 cm times 10 mm/cm = 200 mm
Therefore, a pencil that is 20 cm long is 200 millimeters long.

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]

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.
