Triangle A has angles measuring ninety five degrees, forty five degrees, and thirty degrees. Triangle B has angles measuring one hundred degrees, twenty five degrees, and twenty five degrees. Triangle C has angles measuring fifty degrees, sixty five degrees, and sixty five degrees. Triangle D has angles measuring thirty degrees, one hundred ten degrees, and twenty degrees.
Triangle A
Triangle B
Triangle C
Triangle D
Answer:
Triangle C
Step-by-step explanation:
An acute angle is less than 90 degrees, Triangle C has angles measuring fifty degrees, sixty five degrees, and sixty five degrees. Those numbers are less than 90 degrees. So Triangle C is an acute angle.

m∠B = 4(15°)
m∠B = 60°
A cone has a height of 10 yards and a diameter of 8 yards. What is the volume?
Answer: 167.55 units cubed
Step-by-step explanation:
To find this, you must know the formula for a cone. The area is A=πr(r+h2+r2). We can get that the A=π4(4+102+(4)2). We got this from plugging in the numbers. The radius is equal to half the diameter, so the radius is 4. The answer is 167.55 units cubed.

A figure was created using a rectangle and a triangle. Using the dimensions provided, to find the area of the figure in square feet.
A 18 ft²
B 49 ft²
C 61 ft²
D 82 ft²
Answer:
B. 49
Step-by-step explanation:
For the rectangle:
10 • 4 = 40
For the triangle:
3 • 6 = 18
18/2 = 9
Add them together:
40 + 9 = 49
And there you have it!

Consider the following statement: Two sets of data with the same mean will also have the same variability. Do you agree or disagree with this statement? Explain.
The statement is false and same mean can have different variability
What is Mean?The mean value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values.
Mean = Sum of Values / Number of Values
Given data ,
Let the mean of the data be represented as M
Now , The mean is a measure of central tendency that represents the average value of a set of data, but it does not provide information about the variability or spread of the data.
For example, consider the following two sets of data:
Set 1: 1, 2, 3, 4, 5 (mean = 3)
Set 2: 0, 2, 3, 4, 6 (mean = 3)
Both sets have the same mean of 3, but Set 1 has a smaller range (4) compared to Set 2 (6). The range is a measure of variability that represents the difference between the maximum and minimum values in a set of data.
Hence , two sets of data with the same mean can have different variability,

(geometry) This zigzag crystal vase has a height of 12 inches. The cross sections parallel to the base are always rectangles that are 5 inches wide by 4 inches long.
(a) If we assume the crystal itself has no thickness, what would be the volume of the base?
(b) The crystal is actually half an inch thick on each of the sides and on the bottom. Approximately how much space is contained within the vase?
Answer:
A. 9
B. 7
Step-by-step explanation:
a) The volume of the base of the crystal is 240 inches³
b) The space contained by the vase of the crystal is 24 inches³
What is the volume of a Cuboid?A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges
The volume of a cuboid is the product of its length , width and height
The volume of the cuboid is given by
Volume of Cuboid = Length x Width x Height
Given data ,
(a) Since the cross sections are always cuboids that are 5 inches wide by 4 inches long, the area of each cross section is 5 x 4 = 20 square inches. Since the vase has a height of 12 inches, the volume of the vase is equal to the product of the area of the base and the height, which is 20 x 12 = 240 cubic inches.
(b) If the crystal is half an inch thick on each of the sides and on the bottom, then the dimensions of each cross section are 5 inches by 4 inches by 1 inch (since each side of the crystal adds half an inch to the length and width of the rectangle). The volume of each cross section is therefore 5 x 4 x 1 = 20 cubic inches.
However, since the crystal takes up half an inch on each side, the actual space contained within the vase is reduced by 2 x (5 + 4 + 0.5 + 0.5) x 12 = 216 cubic inches (where 5 + 4 is the sum of the lengths and widths of the rectangle, and 0.5 + 0.5 is the thickness of the crystal on each side).
Hence , the approximate space contained within the vase is 240 - 216 = 24 cubic inches

Antonio is in a bowling league. His goal is to score an average of at least 100 points per game. His scores so far are 105,95,97,82, and 110. How many points can Antonio score in his next game to reach his goal? Show your work.
Antonio can score in his next game a score of 111 to reach his goal.
What are Arithmetic operations?Arithmetic operations are the basic part of mathematics which combines the basic operations like addition, subtraction, multiplication and division.
Given that,
Antonio is in a bowling league. His goal is to score an average of at least 100 points per game.
Total number of games = 6
If each game score is at least 100, total number of scores must be at least 6 × 100 = 600
Scores got so far = 105 + 95 + 97 + 82 + 110
= 489
Score needed for the next game = 600 - 489 = 111
Hence the score needed in the next game is 111.
