As angle Z is bigger than angle Y and angle C must be greater than angle S, we also cannot say that mzC >mZS. The accurate disparity is: mZS >mZC .
how can you describe angle ?An angle is just a geometric shape made up of two rays or splines that meet at a point in the middle known as the vertex. The angle's sides or legs are the rays or dotted lines that make up the angle. T
he standard unit of measurement for angles is the degree, with 360 degrees being one entire circle. Acute angles are those that are less than 90 °, right angles are those that are exactly 90 degrees, obtuse angles are those that are higher than 90 degrees but much less than 180 degrees, & straight angles are those that are exactly 180 degrees.
given
The right response is "mZC > mZS".
The right side of the figure is longer than the left side if RT is bigger than BA. Angle X is greater than angle W, and angle Z is greater than angle Y as a result.
Angles C and S will have the same measure if the triangles are identical because they are matching angles (they are in the same place in each triangle). We are unsure, nevertheless, whether the triangles are comparable.
We cannot therefore assert that mzC = mZS.
As angle Z is bigger than angle Y and angle C must be greater than angle S, we also cannot say that mzC >mZS. The accurate disparity is: mZS >mZC .

Answer:
2) x = 3√5; y = 6;
3) x = 12√2; y = 12;
4) x = 45∘; y = 45∘;
5) x = 60∘; y = 30∘
Step-by-step explanation:
2) Use trigonometry:
[tex] \cos(60∘) = \frac{3}{y} [/tex]
Use the property of the proportion to find y:
[tex]y = \frac{3}{ \cos(60∘) } = \frac{3}{1} \div \frac{1}{2} = \frac{3}{1} \times \frac{2}{1} = 6[/tex]
Use the Pythagorean theorem to find x:
[tex] {x}^{2} = {y}^{2} + {3}^{2} = {6}^{2} + {3}^{2} = 36 + 9 = 45[/tex]
[tex]x > 0[/tex]
[tex]x = \sqrt{45} = 3 \sqrt{5} [/tex]
3) Use trigonometry:
[tex] \sin(45∘) = \frac{12}{x} [/tex]
Use the property of the proportion to find x:
[tex]x = \frac{12}{ \sin(45∘) } = \frac{12}{1} \div \frac{ \sqrt{2} }{2} = \frac{12}{1} \times \frac{2}{ \sqrt{2} } = 12 \sqrt{2} [/tex]
Use trigonometry:
[tex] \tan(45∘) = \frac{12}{y} [/tex]
Use the property of the proportion to find y:
[tex]y = \frac{12}{ \tan(45∘) } = \frac{12}{1} = 12[/tex]
4) Use trigonometry:
[tex] \tan(x∘) = \frac{3}{3} = 1[/tex]
x = 45∘
[tex] \tan(y∘) = \frac{3}{3} = 1[/tex]
y = 45∘
5) Use trigonometry:
[tex] \cos(x∘) = \frac{4}{8} = \frac{1}{2} = 0.5[/tex]
x = 60∘
[tex]x = \sin(y∘) = \frac{4}{8} = \frac{1}{2} = 0.5[/tex]

On Saturday morning, Wendy watched one and a half hours of her favorite shows on television. During the shows there were 18 commercials. What is the unit rate of commercials per hour?
12 commercials per hour
14 hours per commercial
16 commercials per hour
18 commercials per hour
Unit rate of commercials per hour is 12 commercials per hour based on division in mathematics.
We must divide the number of ads by the number of hours in order to determine the unit rate of commercials per hour.
Wendy watched her favourite television programmes for an hour or an hour and a half. There were 18 advertisements running at this time.
So, the unit rate of commercials per hour can be calculated as:
18 commercials ÷ 1.5 hours = 12 commercials per hour
So, it is possible to compute the number of ads each hour as follows: 18 commercials divided by 1.5 hours equals 12 commercials every hour.
Consequently, 12 commercials are broadcast each hour as the unit rate of commercials.
This indicates that while viewing her favorite television programes, Wendy saw 12 adverts every hour on average.
It's crucial to remember that unit rate come in handy when comparing two quantities that are measured using various units. In this instance, we were comparing two different units of measurement: the quantity of advertising and the amount of time in hours. By providing the rate at which the quantity is changing per unit of time, the unit rate enables us to meaningfully compare them.

Answer:
B. $50,000
Explanation:
4%=.04
50,000 x .04=2000
48000/12=4000
She makes $4000 off of her salary each month. Then because she only gets 4% of her commissions you multiply the 50000 by .04 and you get 2000. So she gets $2000 in commissions and $4000 off of her salary.
suppose you have two data sets, a and b, with means of 20 and 30, respectively, and the same standard deviation of 5. which data set is more spread out?
Assuming that we have two data sets, a and b, with means of 20 and 30, respectively, and the same standard deviation of 5, we can conclude that neither data set is more spread out than the other.
What do we understand by sparse data set?Suppose you have two data sets A and B, with means of 20 and 30, respectively, and the same standard deviation of 5. To determine which data set is more spread out, we need to compare the variance of the two data sets. Since the variance is the square of the standard deviation, we can compare the variances of the two data sets. Using the formula, Var = s², we can calculate the variances of data set A and B.
[tex]Var(A) = (5)^2 = 25\\Var(B) = (5)^2 = 25[/tex]
Both data sets have the same variance, indicating that they have the same amount of spread, or convergence. Therefore, we can conclude that no data set is more spread out than the other.

Tina and carl share a 20 ounce bucket of clay 3/10 and 3/5
Tina and Carl will use 6 and 12 ounces of clay, respectively. Tina uses 3/10 of the 20-ounce bucket and Carl uses 3/5 of the 20-ounce bucket.
To determine how much clay Tina and Carl will use, we need to first find the total amount of clay they will use together.
If 3/10 of the clay is used by Tina and 3/5 of the clay is used by Carl, we can find the total amount of clay used by adding these fractions:
3/10 + 3/5 = (3/10 * 1/2) + (3/5 * 1/2) (we multiply by 1/2 to find the common denominator of 10)
= 3/20 + 6/20
= 9/20
Therefore, Tina and Carl will use a total of 9/20 of the 20-ounce bucket of clay.
To find how much each of them will use, we can multiply the total amount of clay by each person's fraction:
Tina: (3/10) x 20 ounces = 6 ounces
Carl: (3/5) x 20 ounces = 12 ounces
Therefore, Tina will use 6 ounces of clay, while Carl will use 12 ounces of clay.

The difference between the tens digit and ones digit of a two-digit number is 2. The number is 27 greater than the number created when the digits are reversed. What is the two-digit number?
Thus, the two digits are 9 and 11.
What is the Two-Variable Equations?
Two-variable equations are algebraic equations that involve two variables, typically x and y, and describe a relationship between them.
Let's call the tens digit "T" and the ones digit "O". Based on the problem, we know that:
T - O = 2 (the difference between the tens and ones digit is 2)10T + O = 10O + T + 27 (the number is 27 greater than the number created when the digits are reversed)T = 2 + O
Then substitute this equation in 10T + O = 10O + T + 27 i.e.
10T + O = 10O + T + 27
10T - T = 10O - O + 27
9T = 9O + 27
9(2 + O) = 8O + 27
9(2 + O) = 8O + 27
18 + 9O = 8O + 27
9O - 8O = 27 - 18
O = 9
Then,
T = 2 + 9
T = 2 + 9
T = 11

If the vertex of the function is at the. 0, 0. 5 what is the recommended amount of mulch for a flower bed with a radius of 20 feet round to the nearest 10th if necessary
the recommended amount of mulch for the flower bed with a radius of 20 feet and a desired depth of 0.5 feet is approximately 628.3 cubic feet.
The given information about the vertex of the function does not appear to be relevant to the question about mulch for a flower bed. However, we can still solve the problem using the given radius of the flower bed.
The formula to find the recommended amount of mulch for a circular flower bed is:
Mulch = π * r^2 * d
Where r is the radius of the flower bed and d is the desired depth of the mulch.
Assuming a desired depth of 0.5 feet, we can plug in the given radius of 20 feet to the formula:
Mulch = π * (20 feet)^2 * 0.5 feet
Mulch = π * 400 square feet * 0.5 feet
Mulch = 200π cubic feet
To find the approximate value in decimal form, we can use the approximation π ≈ 3.14:
Mulch ≈ 200 * 3.14
Mulch ≈ 628 cubic feet
Rounding to the nearest tenth, we get:
Mulch ≈ 628.3 cubic feet
Therefore, the recommended amount of mulch for the flower bed with a radius of 20 feet and a desired depth of 0.5 feet is approximately 628.3 cubic feet.

Paul gets $5 every week for doing his chores. He is saving his money to buy a skateboard that costs $85. He has already saved $25.
Which equation describes the number of weeks (w) that it will take Paul to save enough money to buy the skateboard?
Let x be the number of weeks it will take Paul to save enough money to buy the skateboard.
In one week, Paul earns $5, so in x weeks he will earn 5x dollars.
Since he already has $25 saved, the total amount of money he will have after x weeks is:
5x + 25
To be able to buy the skateboard that costs $85, Paul needs to save up an additional:
85 - 25 = 60
Therefore, we can set up the following equation to find the number of weeks it will take Paul to save up enough money:
5x + 25 = 60
Simplifying and solving for x:
5x = 35
x = 7
Therefore, it will take Paul 7 weeks to save up enough money to buy the skateboard.
The equation that describes the number of weeks (w) that it will take Paul to save enough money to buy the skateboard is:

The other options are not examples of a uniform probability distribution.
(a) The probability of reaching a temperature of 75F on any given day of the year in St. Louis, MO is not a uniform distribution because the probability of reaching 75F is not the same throughout the year, and is influenced by many factors like seasonal variation, climate changes, etc.
(b) A time period in which it rained 25% of the time and did not rain 75% of the time is not a uniform distribution since the probability of rain is not equally likely across the time period.
(d) Flipping a coin two times and recording whether heads or tails is also not a uniform distribution as the probability of getting heads or tails is not the same, it is 0.5 for each individual flip, but the probability of getting two heads, two tails or one head and one tail are different.
Therefore, the correct option is (c) The probabilities of drawing any individual card in a deck with one draw

Answer:
95.2 square yards
Step-by-step explanation:
8(3) + 2(1/2)(3)(7.2) + 2(1/2)(8)(6.2)
= 24 + 21.6 + 49.6 = 95.2 square yards
