Answer:
1.62 yards
Step-by-step explanation:
[tex]\frac{65}{3} =21.666666[/tex]
[tex]\frac{100}{21.6} = roughly 4.62[/tex]
This means that there are 4.62 yards in the final product.

Find the angle measures. Justify your responses. Given: a||b, m1=71º Find m5, m8
I NEED THIS ANSWER BY TUESDAY THE 1ST!!! PLEASE ANSWER!!!
Answer:
The measure of angle MNP is
m ∠ MNP = (x - y)/2
Explanation:
The image attached shows the figure corresponding to this question.
The angle MNP, which is also the angle LNP, is formed by the intersection of a secant and a tangent to a circle.
Then, you can use the theorem:
the angle formed by a secant and a tangent to a circle that intersect outside the circle is half the difference of the major arc minus the minor arc.
The major arc formed is identified with the letter x and the minor arc is identified with the letter y. Thus, the measure of the angle MNP is half the difference x - y:
m ∠ MNP = (x - y)/2

1. Mark charges $10 an hour to babysit with an additional flat fee of $20 for each babysitting job. He wants to purchase a new game system that will cost him $123.50. Write an inequality to show the least number of complete hours he needs to babysit if he has one job scheduled.
A. Solve the inequality that you created.
B. Mark is considering changing his rate to $ 15.00 an hour with no flat fee. What effect would this change have on the hours that Mark needs to work to buy the gaming system?
C. What conclusions can you draw about Jamie charging the flat fee and not charging the flat fee?
Please help!!
Answer:
Step-by-step explanation:
A.123.50≤20+10(x)
103.50≤10x
10.35 hours at least to equal the 123.50.
10.35 hours *10 an hour is 103.50+20 flat fee=123.50
B. 123.50≤15(x)
8.24 hours or more. 15.00 an hour at 8.24 hours = 123.60
C. He will work less hours if he charges more and does not charge the flat fee.
Answer: let x = amount of hours worked.
A. 10x + 20 >or= 123.50 --- 10x >or= 143.50 --- x >or= 14.35 hours.
B. 15x >or= 143.50 --- x >or= 9.57 hours.
C. Jamie would only have to work 9.57 hours to get his gaming system if he charged 15$ with no flat fee as opposed to 14.35 hours of work with the flat fee.

Solve the following equation:
4(x−3)=48−8x
A. x = 5
B. x = 12
C. x = 60
D. x = -5
Answer:
The answer is A
Step-by-step explanation:
4(x-3=)=48-8x
4(5-3)=48-8*5
20-12=8 48-40=8
8=8
Hope this answers your question
Answer: x =5 4x-12=48-8x add 12 to both sides 4x-12+12=48-8x+12 Simplify 4x=-8x+60 add 8× to both sides 4x+8x=-8x+60+8x Simplify 12x=60 Divide both sides by 12 f{12x}{12}={60}{12} x=5
Which situation cannot be represented by the equation x + 12 = 30?

B. James ran 12 miles on Monday and 30 miles on Tuesday. What is, x, the total number of miles James ran all together?
C. Total snowfall for the winter was 30 inches. In January, it snowed 12 inches. What is x, the amount of snow that fell during the other winter months?
D. Juanita spent $30 at the store buying a shirt and shorts. She bought a shirt for $12. What is the cost, x, of the shorts?
Answer:
B
Step-by-step explanation:
The equation would be 12 + 30 = x, because the amount of miles James ran all together would be the sum (what the numbers add up to).
Let x be a positive integer, and define the integers n=x^2+2x+17 and d=2x+5. When dividing n by d, the quotient is x, and the remainder is 7. Find x.

Answer:
I GOT U HOMIE!!! I was having the same issue just went through the pain of guess and check really hope this helps! y=-6x/9+15
Step-by-step explanation:
The equation of the line is y = -(2/3)x + 15
What is the point-slope form of a line?If m is the slope of the line that passes through the point (x₁, y₁), then the equation of the line is y - y₁ = m (x - x₁).
Given the image of the line.
The graph of the line passes through points (12,7) and (9,9).
The slope of the line that passes through points (12,7) and (9,9) is:
m = (9 - 7)/(9 - 12)
m = -2/3
The equation of the line that passes through the point (12,7) and has a slope if m = -2/3 is:
y - 7 = -2/3(x - 12)
y = -(2/3)x + 8 + 7
y = -(2/3)x + 15
Hence, the equation of the line is y = -(2/3)x + 15

Answer: output = -1n + 7 or -n + 7
n can represent any number.
Step-by-step explanation: using the slope-intercept form y = mx + b
y is the output. x is any input. m is the slope. b is the constant.
Calculate the slope: rise ÷ run
You see all the inputs in the chart are going up by 1. This is the run +1
You see all the outputs going down by 1. This is the rise: -1
So the slope, m, is rise / run . -1/1 = -1
To find the constant, use the slope with any pair of inputs and outputs from the chart in place of y and x in the slope-intercept equation.
y = mx + b becomes 6 = -1(1) + b . Solve for b
6 = -1 + b
6 +1 = -1 +1 + b
7 = b
Now set up the equation that answers the question using the calculated values of m and b.
y = -1(x) + 7 . We can answer the question with this equation rewritten a bit:
Output = -1n + 7
or -n + 7 as 1 is usually implied.

What is the ratio of 1.5-inch screws to 2.5-inch screws, written in three different ways? Do not reduce.
Answer:
2:10
Step-by-step explanation:
The Ratio of 1.5-inch screws to 2.5-inch screws = 36/12 = 12/4 = 6/2 = 3/1
What are Ratios?A ratio is a relationship between two things when it is expressed in numbers or amounts.
Given that a carpenter needs 36 screws that are 1.5 inches long, 24 screws that are 2 inches long, and 12 screws that are 2.5 inches long.
