Solve for x and state the measure of the angles with an x in them
Answer:
x = 83
Step-by-step explanation:
The sum of the angles of a quadrilateral is 360
75+x+97+105 = 360
Combine like terms
x+277=360
Subtract 277 from each side
x+277-277=360-277
x = 83

Jessica is 8 years old. Kayla is 6 years younger than twice Jessica’s age. Which expression represents Kayla’s age?
A. (8*6)-2
B. ( 8*2) -6
C. 8*(6-2)
D. 8* (2-6)
Answer:
B
We find twice Jessica’s age and then subtract 6 since she is 6 years younger than that.
Answer:
B. (8*2) -6
Step-by-step explanation:
Since Jessica is 8, and Kayla is 6 years younger than twice (doubled) Jessica's age, this means that Kayla is 6 years younger than 16. Therefore the equation would be (8*2)-6.

Find the slope of a line parallel to 3x – y = 1.
A. –3
B. 3
C. one third
D. negative one third
Answer:
m =3
Step-by-step explanation:
3x – y = 1
First put the line in slope intercept form
y = mx+b where m is the slope and b is the y intercept
-y = -3x+1
y = 3x-1
The slope is 3
We want a line parallel, which means the lines have the same slope
m =3

A cell phone company wants to determine the average amount of data that their smart phone customers use each month. Which group would best represent a sample of the population?
one thousand of their customers with the most expensive monthly plans
one thousand of their customers who most recently signed up with the company
one thousand of their customers with a current smart phone data plan
one thousand of their customers who called in for technical support
The group that best represents a sample of the population is one thousand of their customers with a current smart phone data plan.
What is the appropriate sample of the population?
A sample is a smaller representative group of the population. A sample is used as it might not be feasible or cost effective to access the whole population.
The appropraite sample should be representative of the whole population of customers.
To learn more about sample, please check: https://brainly.com/question/18521835
The group that would best represent a sample of the population is given by: Option C: one thousand of their customers with a current smart phone data plan.
Why do we do sampling?We do sampling so that we don't have to work on entire population of items but only on that sample in a way that we can predict information about population.
Most of the times, it isn't possible in real world to work on entire populations. Samples come out for rescue by assumptions that they will have some properties of the population pertained in them.
Thus, the sample should be taken out such that it includes data of the population as much as it can in unbiased way so as to imitate population. (assuming that we want the sample to contain the summary of the population).
We've to collect sample in such a way that we can get a widespread view of the population (all customers). We want to do sampling for getting the average amount of data that their smart phone customers use each month.
Option A, B and D are choosing those customers, which are like a special part of the customers, and not an overall coverage of the customer the cell phone company has.
But option C covers assumingly all sorts of customers who use internet data.
Thus, the group that would best represent a sample of the is given by: Option C: one thousand of their customers with a current smart phone data plan

Think of 5 positive integers that have a mode of 4, a median of 6, a mean of 7 and a range of 10.
Answer:
6 6 6 6 11
Step-by-step explanation:
The median is the middle number
the mode is the number of items, usually the number that are the same.
the mean is the average
the range is the number between the smallest and the largest.
So the information you have makes 4 of the 5 numbers the same.
The middle number is 6. This is an interesting fact because it means that 4 of the five numbers are 6
x 6 6 6 6 or 6 6 6 6 x is what you know so far.
The range is a bit of a devil. And so is the mean. We need the mean to be related to 5*7 = 35. So the sum of the five numbers equals 35. The range would have to be 5, I think. (35 - 4*6) = 11
The difference between 11 and 6 = 5
So 11 works for everything but the range.
If the range must be ten, then x = 16 but then the mean = 8 and 7 is incorrect
So I can get 3 out of 4, but not them all.

Eli will photograph a wedding for a flat fee of $1560 or for an hourly rate of $180. For what lengths of time would the hourly rate be less expensive?
The hourly rate would be less expensive if the wedding was less than
? hours long.
(Simplify your answer.)
Answer:
The hourly rate is better between 1 and 8 hours.
Step-by-step explanation:
There are two options
A fixed amount of $1560.
Or an hourly rate of $180 the hour.
So for the first option, the cost equation as a function of time, t, is:
f(t) = $1560
(it does not depend on t)
While for the second option, the equation would be:
g(t) = $180*t
First, we want to answer:
We can expect that for smaller values of t the second option is better but let's see that:
or what lengths of time would the hourly rate be less expensive?
Then we need to solve:
f(t) = g(t)
for t, this is:
$1560 = $180*t
$1560/$180 = t = 8.66
So, for t = 8.66, the cost is the same in both options.
For t < 8.66
(between 1 and 8 hours) the second option is better. (here the hourly rate is better)
for t > 8.66
(9 hours or more) is better the first option, as the hourly (here the flat fee is better)
Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures cell phones can be modeled by the polynomial 2x2 + 55x + 10. The cost, in dollars, of producing the cell phones can be modeled by 2x2 – 15x – 40. The variable x represents the number of cell phones sold.
What expression represents the profit, and what is the profit if 240 cell phones are sold?
40x – 30; $2,400
40x – 30; $9,570
70x + 50; $16, 850
70x + 50; $28,800
Answer:
C
Step-by-step explanation:
Given that the equation of the revenue is R=2x2+55x+10 and the equation of the cost is C=2x2 – 15x – 40, you will get the profit by subtracting the revenue from the cost: R-C=P. Therefore, P=(2x2+55x+10)-(2x2 – 15x – 40). You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars.
The profit, if 240 cell phones are sold, is $16,850.
Profit = 70x + 50
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The profit, in dollars, can be found by subtracting the cost from the revenue:
Profit = Revenue - Cost
= (2x² + 55x + 10) - (2x² - 15x - 40)
= 70x + 50
The expression for profit is 70x + 50.
To find the profit if 240 cell phones are sold, we substitute x = 240 into the expression for profit:
Profit = 70x + 50
= 70(240) + 50
= 16,850
Therefore,
The profit, if 240 cell phones are sold, is $16,850.
