Answer:
x=10
Step-by-step explanation:
A straight line has an angle of 180 degrees. To solve for x we can add all the given angles and set them equal to 180.
[tex]180= 5x-1+9x+8+2x+13[/tex]
Then combine all the common factors
[tex]180=16x+20[/tex]
And then you can solve for x
[tex]180= 16x+20\\160=16x\\10=x[/tex]
To check if x is correct you can plug in 10 to each equation. If all the equations add up to 180, then x is correct
[tex]5(10)-1= 49\\9(10)+8= 98\\2(10)+13= 33\\\\49+98+33=180[/tex]

77. The yearly cost of tuition (in-state) and required fees for
attending a public two-year college full time can be esti-
mated by the linear function f(x) = 64x + 2083, where x
is the number of years after 2000 and f(x) is the total cost.
(Source: The College Board)
a. Use this function to approximate the yearly cost of
attending a two-year college in the year 2016. (Hint: Find
f(16).]
b. Use the given function to predict in what year the yearly
cost of tuition and required fees will exceed $3200. [Hint:
Let f(x) = 3200, solve for x, then round your solution
up to the next whole year.]
c. Use this function to approximate the yearly cost of
attending a two-year college in the present year. If you
attend a two-year college, is this amount greater than or
less than the amount that is currently charged by the col-
lege you attend?
Answers
Answer:
a. [tex]\$3107[/tex]
b. 17 years
c. The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.
Step-by-step explanation:
a.
[tex]f(x)=64x+2083[/tex]
Here, x is a the number of years after 2000 and f(x) is the total cost.
To approximate the yearly cost of attending a two-year college in the year 2016, find [tex]f(16)[/tex].
[tex]f(16)=64(16)+2083\\\\=1024+2083\\\\=\$3107[/tex]
b.
To predict in what year the yearly cost of tuition and required fees will exceed $3200, solve [tex]f(x)=3200[/tex]
[tex]64x+2083=3200\\\\64x=3200-2083\\\\=1117\\x=\frac{1117}{64}\\\\ =17.45[/tex]
So,
x is approximately equal to 17 years.
c.
The present year is 2020.
To approximate the yearly cost of attending a two-year college in the present year, find [tex]f(20)[/tex]
[tex]f(20)=64(20)+2083\\\\=1280+2083\\\\=\$3363[/tex]
The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.

An isosceles triangle has two congruent angles and two congruent sides.
Which conjecture is disproved by Taryn's counterexample?
A. If a polygon is regular, all angles will be congruent and all sides will be
congruent.
B. One angle in an isosceles triangle is always obtuse.
C. The number of congruent sides in a triangle determines the number of congruent
angles.

Winning the jackpot in a particular lottery requires that you select the correct three numbers between 1 and 44 and , in a separate drawing, you must also select the correct single number between 1 and 41. Find the probability of winning the jackpot.
Answers
Answer:
[tex]\frac{1}{3,492,544}[/tex]
Step-by-step explanation:
Since winning the lottery as described in the question is a series of events that need to occur in a sequence in order for it to be a winning ticket then this is a dependent event. Therefore to find the probability of actually winning we multiply the probability of getting each number which is calculated by dividing the amount of times the number appears by the total amount of numbers.
For example the first three numbers are 1 out of 44 therefore the probability of hitting just one correct number is [tex]\frac{1}{44}[/tex] ... now we multiply
[tex]\frac{1}{44} * \frac{1}{44} * \frac{1}{44} * \frac{1}{41} = \frac{1}{3,492,544}[/tex]
(Multiplying fractions is simply multiplying the numerators together and then the denominators together) Finally we see that the probability of actually winning the jackpot is [tex]\frac{1}{3,492,544}[/tex]

a student worked out at the gym continuously for 50 minutes. The graph shows the remaining percentage of the workout f(x) as a linear function of x, the time in minutes
Answers
Answer:
Domain: All real numbers greater than or equal to 0 and less than or equal to 50
Range: All real numbers greater than or equal to 0 and less than or equal to 100
Step-by-step explanation
The workout is at 100% at 50 mins. Anything less would be under these two numbers. Since the percentage of workout is on the y-axis, anything between zero and 100 can be possible. The time is on the x-axis, so anything 0 to 50 can be possible.
The surf instructor has an initial fee of $12 and charges $8 per hour for lessons, which is represented by the equation y = 8x + 12, where x is the number of hours and y is the total cost. The instructor gives 32 hours of lessons a month to Sandra and 24 hours of lessons a month to Bela. What is the total amount the instructor makes in a month?
Sandra: y = 8 (32) + 12. y = 256 + 12. y = 268. The instructor receives 268 dollars a month from Sandra.
Answers
Answer:
Step-by-step explanation:
Y=8(32)+12

Mount McKinley is Alaska is 5910 feet higher
than Mount Rainier in Washington. Together,
their heights total 34,730 feet. How high is each
mountain?
Answers
Answer:
20,320 feet
Step-by-step explanation:
Let Mt Rainer be X.
Let Mt KcKinley be X+5,910.
So, X + (X + 5,910) = 34,730
Combine the variables and, 2X + 5,910 = 34,730
Subtract 5,910 from both sides and, 2X = 28,820
Divide both sides by 2 and, X = 14,410
So, Mt Rainer is 14,410 and Mt McKinley is (14,410 + 5,910) = 20,320
Answer:
Mount McKinley = 34,730
Mount Rainier = 28,820
Step-by-step explanation:
Step 1:
x + 5,910 = 34,730 Equation
Step 2:
x = 34,730 - 5,910 Subtract 5,910 on both sides
Step 3:
x = 28,820
Step 4:
28,820 + 5,910
Answer:
Mount McKinley = 34,730
Mount Rainier = 28,820

|x-4|=6x+16 solve equation please
Answers
Step-by-step explanation:
|x-4|=6x+16 To find the absolute value :
x - 4 = 6x + 16 or x - 4 = -6x - 16 for first equation
x - 4 = 6x + 16 export like terms to the same side of the equation
-4 - 16 = 6x - x (The terms chages signs from negative to positive and from positive to negative when exported to the other sideof the equation)
-20 = 5x divide by 5
-4 = x
For the second equation
x - 4 = -6x - 16 export like terms to the same side of the equation
x + 6x = -16 + 4
7x = -12
x = 1.7 approximately
