Step-by-step explanation:
Points to remember
Measure of angles on the semicircle is 90°
From the figure we can see a semicircle and a triangle inscribes on it.
To find the measure of <XYZ
Here <XYZ is on the semicircle that is angle XYZ is a right angle.
Therefore m<XYZ = 90°
The correct answer is option A. 90°
Answer:
Step-by-step explanation:
Any triangle inscribed in a semicircle has one right angle. Here it's <XYZ.
Answer:
11.41= 6x=2.11
x=1.35
Step-by-step explanation:
B false
C cannot be determined
A. x + 7y = 320
y = 7x
B. x + y = 7
y = 320x
C. x + y = 320
y = 7x
D. x−y=320
y = 7x
2. Nancy bought 360 tropical fish for a museum display. She bought 8 times as many goldfish as angelfish.
How many of each type of fish did she buy?
A. 40 angelfish, 320 goldfish
B. 160 angelfish, 200 goldfish
C. 20 angelfish, 160 goldfish
D. 320 angelfish, 40 goldfish
3. Michael and Kathryn bowl together and their combined total score for one game was 425 points. Michael’s score was 70 less than twice Kathryn’s. What were their scores?
Which is a system of equations to model the problem if x represents Kathryn’s score and y represents Michael’s score?
A. x + y = 70
y = 2x – 425
B. x + y = 425
y = 2x – 70
C. x – y = 425
y = 2x – 70
D. x + y = 425
y = 2x + 70
4. Michael and Kathryn bowl together and their combined total score for one game was 425 points. Michael’s score was 70 less than twice Kathryn’s.
What were their scores?
A. Kathryn: 260, Michael: 165
B. Kathryn: 150, Michael: 275
C. Kathryn: 275, Michael: 150
D. Kathryn: 165, Michael: 260
5. A collection of nickels and dimes is worth $6.10. There are 67 coins in all.
How many nickels are there?
A. 12
B. 18
C. 49
D. 55
Answer:
D
Step-by-step explanation:
If im wrong, please correct me in the comments.
Answer:
5. D, Let d represent the number of dimes and n represent the number of nickel. We have been given that a collection of coins has 67 coins in all. This means that total number of nickels and dimes is 67. We can represent this information in an equation as:
Since we know that a dime is worth $0.10, so d dimes will be worth 0.10d.
A nickel is worth $0.05, so n nickels will be worth 0.05n. We are also told that the collection is worth $6.10. We can represent this information in an equation as:
We will use substitution method to solve system of linear equations. From equation (1) we will get, upon substituting in equation (2) we will get, Let us divide both sides of our equation by .

Answer:
Step-by-step explanation:
Given: Kristen made 4 out of 5 throws in her first basketball game, 5 out of 8 in her second game and 5 out of 7 free throws in her third game.
To Find: The experimental probability of Kristen marking her first free throw in her fourth game.
Solution:
There are only two possibilities that the first throw will be free or not.
Hence, the total outcomes = 2
Hence, Probability that the throw is free =
Hence, 1/2 is the experimental probability of Kristen marking her first free throw in her fourth game.
After addressing the issue at hand, we can state that As a result, the equation value of x is roughly 10.57 units (rounded to two decimal places).
An equation is a mathematical proclamation that proves the equality of two expressions capable of connecting through an equal sign '='. For instance, 2x - 5 = 13. Explanations include 2x-5 and 13. The '=' symbol links up the two expressions. A mathematical formula containing two formulas on either side of a =) (=) is known as an equation. It depicts the equivalence relationship between left and right methodologies. L.H.S. = R.H.S. (left edge = top half) in any formula.
Using the information provided, we can construct the following equation based on the concept of similar triangles:
x/(9+18) = 10/(BC) (BC)
9 + 18 = 27 = AB = AP + PB
Because triangle ABC is a right triangle (angle B is 90 degrees), we can apply the Pythagorean theorem to calculate the length of segment BC:
BC2 = AB2 - AC2 BC2 = 272 - 102 BC2 = 649 BC = sqrt (649)
When we plug this value into our original equation, we get:
x/(9+18) = 10/sqrt (649)
When we simplify, we get:
x/27 = 10/sqrt (649)
When we multiply both sides by 27, we get:
x = 270/sqrt (649)
As a result, the value of x is roughly 10.57 units (rounded to two decimal places).
