Answer:
y = 119
30 =x
Step-by-step explanation:
61 and y are same side interior angles and they add to 180
61+y = 180
y = 180-61
y = 119
y and 6x-61 are vertical angles and they are equal
y = 6x-61
119 = 6x-61
Add 61 to each side
119 + 61 = 6x
180 = 6x
Divide each side by 6
180/6 = x
30 =x
Answer:
y = 119°
x = 30°
Step-by-step explanation:
We know that if two lines are parallel, the co - interior angles are added up to 180°°.
Accordingly,
y + 61 = 180
y = 180 - 61
y = 119°
Also, we know that, vertically opposite angles are equal to each other.
y = 6x - 61
119 = 6x - 61
Now, we have to make x the subject.
For that, first, add 61 for both sides.
119 + 61 = 6x
180 = 6x
Now, divide both sides by 6.
30° = x

Fleur is making 8 identical thank-you cards for her teachers. each card requires 2.5 sheets of yellow paper and some red paper. she uses a total of 30 sheets of paper. a. write an equation that can be used to determine the number of red sheets, r, required for each card. __
The required equation to determine the number of red sheets, r, required for each card is 8r + 20 = 30.
Let the required number of red paper be r. For one card, the 2.5 sheets of yellow paper are required. So, for 8 thank-you cards, the yellow papers required will be = 8×2.5
Number of yellow papers = 20
Total number of sheets required = Number of yellow sheets for 8 cards + Number of red sheets for 8 cards
Keep the values in formula to form the equation
30 = 20 + 8r
8r = 10
r = 10/8
r = 1.25
So, the equation for calculation of number of red papers for each card is 1.25.

The equation of line parallel to the given line is found as y = -6x + 13.
What is meaning of the term parallel slopes?A line's slope is similar to the slopes of adjacent parallel lines, therefore m1 = m2. Additionally, the equations of a parallel line could be determined by applying the formulas; (y−y1)=m(x−x1) ( y − y 1 or by y = mx + c.The equation of the line is-
y = -6x + 1
The second line is parallel to the above line, thus the slopes of both the line are equal.
m1 = m2 = -6
The new line also passes from the point (1, 7)
(x1, y1) = (1,7)
Thus, the equation of the line will be calculated as-
y - y 1 = m2(x - x1)
y - 7 = -6(x - 1)
y - 7 = -6x + 6
y = -6x + 13
Thus, the equation of line parallel to the given line is found as y = -6x + 13.

Step-by-step explanation:
only limited sense.
first of all, directly it does not make any sense. we can only send integer number of students on a field trip. not half-persons.
therefore, 29.5 students for a single field trip calculation does not make sense.

How many jackets must the owner buy for the total jacket sales to be at least $260? Explain your answer. The owner must buy how many jackets?
The percent of the purchase price that the sales price is 80%.
The number of jackets that should sold so that total sales can be at least $260 is 6.
What is the percent of sales price and the number of jackets to be sold?The equation that can be used to determine the percent of the purchase price the sales price is:
Percent = (sale price / purchase price) - 1
($72 / $40) - 1 = 0.80 = 80%
The sales price of the $25 jackets if prices are increased by 80%
Sales price = (1 + percent) x purchase price
(1 + 0.8) x $25
1.8 x $25 = $45
The number of jackets to sell so that total jacket sales can be at least $260 is:
(sales price per jacket x number of jackets) ≥ $260

suppose goop purchases 150 gallons of raw material. what is the probability that they will run out of raw material?
The probability that they will run out of raw material is 0.78 or 78% if the order quantity is 150 gallons.
We have following information,
the demand for the polymer is distributed normally .
Mean (μ) = 250 gallons and Standard deviations (σ) = 125 gallons
Selling price of poymer = $25 per gallons
cost price of raw material for polymer= $ 10 per gallons
Salvage value = $(-5)/ gallon
Now, Using the formula for normally distributed sample,
Z = ( X - μ ) /σ
where , X---> sample mean
μ ----> population mean
σ----> standard deviations
Z -----> Z-value
from question it is clear X = 150
putting all the values of variables in above formula we get, Z = ( 150-250)/125 = -100/125
= - 0.8
(-0.8) value of z = 0.21 = 21% , the value of z is measure from normal distribution table.
They will run out of raw material if demands exceds this quantity or
Probability ( out of stock ) = 1 - 0.21 = 0.79 = 79%

• C. The graph of g(x) is shifted 2 units right and 3 units
up.
• D. The graph of g(x) is shifted 2 units left and 3 units down.
We deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit up in the graph of g(x). The best choice is C.
Describe a graph.A diagram that shows how a variable varies in relation to one or more other variables, such as a collection of points, lines, line segments, curves, or regions.
Right-shift a function
Inside the function's argument, subtract. For instance, is essentially moved b units to the right.
You go to the right while subtracting from the parameter of the function.
Accordingly, f(x) is moved two units to the right in g(x) = f(x - 2).
also to advance a function
Outside of the function, add. For instance, is essentially shifted up units.
G(x) = f(x - 2) + 3 hence says that f(x) is shifted up by 3 units.
Overall, then, using two transformations, we deduce that g(x) = f(x - 2) + 3 denotes a 2-unit right and 3-unit upswing in the graph of g(x).
Therefore, choice C is right.

the length of time for one individual to get to a construction site is a random variable having an exponential distribution with a mean of 4 minutes. what is the probability that a person gets there in less than 3 minutes on at least 4 of the next 6 days?
The probability that a person gets there in less than 3 minutes on at least 4 of the next 6 days is 0.3969.
Define probability.A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities. By dividing the number of positive outcomes by the entire number of possible outcomes, probability—the likelihood that an event will occur—is determined. The most basic illustration is a coin toss. There are only two outcomes when you flip a coin: either it comes up heads or tails.
Given,
Mean = 4 minutes
= 1/4
= 0.25
The probability that someone will be attended to in less than three minutes on any given day is:
P( X ≤3)
= 1- e⁻⁰²⁵⁽³⁾
= 0.5267
The probability is:
P( X ≥ 4)
= P( X = 4) +P( X = 5 ) + ( X = 6)
= 0.2594 + 0.1159 + 0.216
= 0.3969
