Answer:
120 degrees
Step-by-step explanation:
Angles 1 and 3 are congruent, because they are vertical angles, so we must set them equal to each other, solve for x and plug in x.
Hope this helps :-)
Answer:
3 = 108 degrees
Step-by-step explanation:
2x + 80 = 3x + 60
get the variable and number on different sides
2x + 80 = 3x + 60
2x + 80 - 80 = 2x
3x + 60 - 3x = 60
2x + 3x = 5x
60 + 80 = 140
5x = 140
now divide each side by 5
5x / 5 = x
140 / 5 = 28
x = 28
28 + 80 = 108

A person places $4760 in an investment account earning an annual rate of 1.6%, compounded continuously. Using the formula V=PertV = Pe^{rt}V=Pert, where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 7 years.
Answers
Answer:
$5324.12Step-by-step explanation:
Given that the principal p= $4760
rate r= 1.6% 1.6/100 =0.016
time t= 7years
by applying the expression
[tex]V = Pe^{rt}[/tex]
We have
[tex]V = 4760e^{0.016*7}\\\\ V=4760e^{0.112}\\\\ V=4760*1.11851286065\\\\ V=$5324.12[/tex]
Hence after 7 years the money in the account will be $5324.12

Beth’s annual salary is $20,000. She also earns a variable percent commission on her sales over $500. The percent commission varies on the amount of her sales. If p(x) represents Beth’s percent commission, and f(x) = x − 500, is her amount of sales, which expression represents the commission she earns?
A) p(f(x))
B) f(p(x))
C) p(x) + f(x)
D) p(x) − f(x)

At a little-known vacation spot, taxi fares are a bargain. A 12-mile taxi ride takes 18 minutes and costs $7.20. You want to find the cost of a 46-mile taxi ride. What unit price do you need?
Answers
Answer:
unit cost in dollars per mile
Step-by-step explanation:
You are given cost, miles, and time for a certain trip.
You are asked the cost for a certain number of miles, so you need a unit cost of dollars per mile.
$7.20/(12 miles) = $0.60/mile
$0.60/mile * 46 miles = $27.60
By first finding the unit cost per mile, you can then find the cost of the 46-mile trip.
Answer:
0.40, mile
Step-by-step explanation:
because you had to multiply to get the total cost and then divide the number by the total cost.
At Feet-R-Us colored socks are $5 and white socks are $3. Jimmy buys $32 worth of socks. An equation representing this scenario is 5c + 3w = 32. Solve this equation for c, the cost of 1 pair of colored socks
Answers
Answer:
$5
Step-by-step explanation:
if you want the cost of 1 pair of colored socks, substitute that into c
5(1) + 3w = 32
5 + 3w = 32
subtract on both sides
3w = 27
this means the amount of pairs of white socks is 9.
multiply by 3
$27
then subtract by 32
$5
he only bought 1 pair of colored socks for $5

What is the slope of 12x + 3y =7
Answers
Ik this because I did it
Answer: y = -4x + 7/3 so the slope is -4
Step-by-step explanation:
First, we need to put the linear equation into the slope-intercept form: y = mx + b
We do this by subtracting 12x from both sides, so the equation now looks like 3y = -12x + 7. Now we divide both sides by 3 to get y alone, which gives us y = -4x + 7/3
m is always the slope, so the slope of this line is -4 or -4/1.

assuming that no questions are left unanswered, in how many ways can a six-question quiz with 4-choice multiple choice questions be answered?
Answers
Given:
Total number of questions = 6
Choice for each question (in MCQ) = 4
Assuming that no questions are left unanswered.
To find:
The total number ways to answer the quiz, assuming that no questions are left unanswered.
Solution:
Here, Number of ways to answer each question = 4
To find the total number ways to answer 6 MCQ, we have to have to multiply number of ways to answer each question 6 times.
Total number of ways to answer six-question quiz with 4-choice multiple choice questions is
[tex]4\times 4\times 4\times 4\times 4\times 4=4096[/tex]
Therefore, the required number of ways is 4096.
There are 4096 ways to answer the six-question quiz with 4-choice multiple-choice questions.
We have,
For each question on the quiz, there are 4 choices.
Since each question is independent of the others, the total number of ways to answer the entire quiz can be found by multiplying the number of choices for each question together.
There are 6 questions with 4 choices each.
4 choices for the 1st question * 4 choices for the 2nd question * 4 choices for the 3rd question * 4 choices for the 4th question * 4 choices for the 5th question * 4 choices for the 6th question
= [tex]4^6[/tex]
Using exponential notation,
[tex]4^6[/tex] = 4 * 4 * 4 * 4 * 4 * 4 = 4096
Therefore,
There are 4096 ways to answer the six-question quiz with 4-choice multiple-choice questions.

The following table shows how far a runner has gone in t minutes. Which of the following equations represents this information?
A. t = 350d
B. t = 300d + 100
C. d = 350t
D. d = 300t + 100 Minutes (t) Meters (d)
2 700
3 1,050
5 1,750
10 3,500
Answers
Answer:
d = 350tStep-by-step explanation:
From the information given, we need to get the rate of change of distance which is the velocity (slope.)
velocity = Δd/Δt
v = d2-d1/t2-t1
from the table;
when t = 2, d = 700
when t = 3, d = 1050
v = 1050/750/3-2
v = 350/1
v = 350
Since v = d/t
350 = d/t
cross multiply
350t = d
Rearrange:
d = 350t
Hence the equation that represents the information is d = 350t

Find the value of x. Then find the angle measures of the polygon.
Please help me as soon as possible, it would be great if you gave me an explanation!
Answers
For number 20:
Because a triangle is 180 degrees, we will equal all the angles we know to that. So, this is how we will write our equation:
Solve for x:
60 + x + 20 + 3x = 180
4x = 100
x = 20
Using 75, you can find the angle measure by plugging 75 where x is present in the angle measures. For example:
x = 20,
20 + 20 = 40
3(20) = 60
-
For number 21:
The shape shown is basically two triangles, so 180 x 2 is 360. Again, same procedure. Add all known angle measures and make an equation where they all equal 360.
Solve for x:
x-5+x+35+1.4x+x=360
x = 75
By isolating x, you should get an answer of 75. Now, plug that into each of the equations:
x = 75
75 + 35 = 110
75 - 5 = 70
1.4(75) = 105
