Answer:
<XYZ = 83
Step-by-step explanation:
we can see that the line XY is tangent to point Y
we can also the see that <XYZ intersects the line that forms arc 166
when a tangent line intersect the line that forms an arc, the angle formed by the tangent will be equal to half of the arc
so in other words angle XYZ is 0.5 of Arc 166
so <XYZ = 83

- When solving problems like these (One-Step Equations,) to get x alone you must do the opposite of what you see.
- In this situation we have a positive 3. So to get rid of both numbers you do the opposite: Opposite of +3 is -3. So you subtract 3 from each number.

a long-distance telephone call costs $1.65 for the first 3 minutes and $0.42 for each additional minute. how much will a 23-minute call cost
Answers
Answer:
About $43.69.
Step-by-step explanation:
1.65+0.42t=20 you minus the 3 minutes from the 23 minutes because those are paid for by the 1.65. Then for every extra minute, you pay 42 cents.
1.65+0.42t=20
Subtract the 1.65
0.42t=18.35
t≈43.69

The name of every student taking Algebra was listed alphabetically and numbered. The teacher uses
an arithmetic sequence to call on students. The numbers of the first 3 students are listed below.
What will be the number of the 25th student chosen?
9,6, 3...
Answers
Answer:
The number will be -63
Step-by-step explanation:
Here, we want to give the number of the chosen 25th student
We can see that the numbering follows an arithmetic sequence where a = 9 and d which is the common difference is (6-9) = -3
Mathematically, we can calculate the nth term using the equation below;
Tn = a + (n-1)d
in this case, n = 25, a = 9 and d = -3
So we have
Tn = 9 + (25-1)-3
Tn = 9 -3(24)
Tn = 9-72
Tn = -63
what is. the value of x in the equation 2.5(6x-4)=10+4(1.5+0.5x)?
Answers
Answer:
x=2
Step-by-step explanation:
We first distribute this. So we have 15x-10 = 10 + 6 +2x.
Then we move the variable to one side and have 13x= 10+10+6
Simplify to get 13x = 26.

Erica purchased adult and youth tickets for a movie. She bought x adult tickets for $7 each and y youth tickets for $5. Write an expression that can be used to show the total cost, C, of all tickets.
PLZ HELP IM FALING :o
i will give brainlyest
Answers
Answer:
C = 7x + 5y
Step-by-step explanation:
Algebraic Expressions
Erica purchased tickets for a movie. It's given each adult ticket cost $7 and each youth ticket cost $5.
If each adult ticket cost $7 and she bought x tickets, then she spent 7x dollars on adult tickets.
Similarly, if each youth ticket cost $5 and she bought y tickets, then she spent 5y dollars on youth tickets.
The total cost C is the sum of the individual costs, thus:
C = 7x + 5y

WORTH 15 POINTS!! - Eileen's Energy Bars has determined that an energy bar measuring 3.25 inches long has a z-score of +1 and an energy bar measuring 3.50 inches long has a z-score of +2.
What is the standard deviation of the length of energy bars produced at Eileen's Energy Bars?
3.5
3.25
0.75
0.25
Answers
Answer:
0.25
Step-by-step explanaition:
The z-score represents how many deviations a value is from the mean. When the bar measures 3.25, the z-score is +1. When the bar measures 3.50, the z-score is +2. You'll notice that whenever the bar size increases by 0.25, the z-score goes up +1. So, the standard deviation from the mean must be 0.25.

A school district has decided that students in grades 7 through 12 should receive 400 minutes of physical education every 10 school days. A gym teacher at one of the schools believes that his students are not meeting this criterion. She randomly selects 50 students and it is found that her students have a mean of 385 minutes and a standard deviation of 55 minutes. Is this evidence to support her claim?
Answers
Answer:
Yes
Step-by-step explanation:
Based on the information provided we can say that Yes, this is enough evidence to support her claim. Since the 50 students were randomly selected and the physical education criteria applies to all of the students in that grade range then these 50 students perfectly represent the total population. That being the case, the results gathered to show that with a standard deviation of 55 minutes some students are surpassing the requirement by very little but others are falling very far from that requirement. When it is a requirement for all of the students in that grade range. Therefore, it is enough to support her claim.

Cheddar cheese cost 4.25 per pound. Which equation best represents y, the cost of x pound of cheddar cheese
Answers
Answer:
y = 4.25x
Step-by-step explanation:
Cheddar cheese cost 4.25 per pound . This means the cost of cheddar cheese is 4.25 for every pound in weight. Assuming we put a currency to the value we can say 1 pound of cheddar cheese is equals to 4.25 dollars($4.25). Mathematically, it can be represented as
4.25 is the cost for 1 pound of Cheddar cheese
Let the cost of the equation be y as required from the question.
y = cost of the cheddar cheese
x is the weight value in pounds of the Cheddar cheese.
The equation can be best represented as
y = 4.25x
In the equation above if the amount in pounds is 3 pound . the value will be inputted for x and the cost will be gotten which is y.

1 - 3x = 3x + 1 solve for x
Answers
Answer: x = 0
Step-by-step explanation:
1 - 3x = 3x + 1
then add 3x on both sides
1 = 6x + 1
then subtract 1 on both sides
0 = 6x
then divide by 6 on both sides
0 = x
so x = 0
Answer:
x would be unknown bc there wouldnt be an answer since
1-3x=3x+1
if we take away 1 forom both sides were left with -3x=3x and it would be 6x if we combined them which can be possible bc it would be nothing = 6x if that makes sense

3x2 - 2x - 1?
Answers
Answer:
[tex]x^{4}[/tex] + 3x³ - 3x - 1
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = lw ( l is the length and w the width ) , thus
A = (3x² - 2x - 1)(x² + x + 1)
Each term in the second factor is multiplied by each term in the first factor, then
A = 3x²(x² + x + 1) - 2x(x² + x + 1) - 1(x² + x + 1) ← distribute parenthesis
= 3[tex]x^{4}[/tex] + 3x³ + 3x² - 2[tex]x^{4}[/tex] - 2x² - 2x - x² - x - 1 ← collect like terms
