Dylan has 1,024 in credit card debt. The credit card has an APR of 15% and is compounded monthly. If he pays 300 per month, how long will it take to pay off the credit card?
Answer:
2.1314 Months.
Step-by-step explanation:
The time it will take to pay off the credit card is 3.86 months.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest =P(1+r/n)^rt
We are given that;
Debt credit card= 1024
APR=15%
Now,
FV is the remaining balance of the credit card debt, PMT is 300, i is 0.15/12 (the APR divided by 12 months), and n is the number of months. We want to find n when FV is zero, which means the debt is paid off. So we have: 0=300×0.15/12(1+0.15/12)n−1
Solving for n, we get: n=log(1+0.15/12)log(1−0.15/12×0/300)≈3.86
Therefore, by the given interest rate the answer will be 3.86 months .

A. 3.5
B. 4
C. 10
D. 10.5
Answer:
A. 3.5
Step-by-step explanation:
Given that AB is parallel to A'B', therefore,
CB/CB' = CA/CA'
CB' = 7
CB = CB' + BB' = 7 + BB'
CA' = 6
CA = CA' + AA' = 6 + 3 = 9
Plug in the values
(7 + BB')/7 = 9/6
(7 + BB')/7 = 3/2
Cross multiply
2(7 + BB') = 7(3)
14 + 2BB' = 21
Subtract 14 from both sides
2BB' = 21 - 14
2BB' = 7
Divide both sides by 2
BB' = 7/2
BB' = 3.5

517.28
Step-by-step explanation:
42.4 x 12.2= 517.28
Answer:
517.28
Step-by-step explanation:
An object is launched directly in the air at a speed of 72 feet per second from a platform located 12 feet above the ground. The position of the object can be modeled using the function f(t)=−16t2+72t+12, where t is the time in seconds and f(t) is the height, in feet, of the object. What is the maximum height, in feet, that the object will reach?
Answer:
93 feet
Step-by-step explanation:
The highest point the object will be the vertex of the given function. Because the derivative of the function at the vertex is zero, we can set up the equation f'(t)=0. After substituting, we get t=2.25 as the x coordinate. when we plug this vaule we get 93.
Find the 91st term of the arithmetic sequence 28, 8, –12, ...
Anybody know the answer?
Answer:
-1772
Step-by-step explanation:
The nth term of an arithmetic sequence is expressed as;
Tn = a+(n-1)d
a is the first term
n is the number of terms
d is the common difference
From the sequence
a = 28
d = 8-28 = -12-8 = -20
n =91(since we are looking for the 91st term)
Substrate
T91 = 28+(91-1)(-20)
T91 = 28+90(-20)
T91 = 28-1800
T91 = -1772
Hence the 91st term is -1772
6. Becca is helping to sell tickets to the spring musical. They sold 135 tickets and collected $799. Each student ticket costs $5 and each adult ticket costs $7. Define the variables, and write a system of equations to find out how many student tickets and adult tickets were sold. Label everything for full credit!
Answer:
$400 dollars in five dollar tickets then $399 dollars in seven dollar tickets.
so you do $400+$399=799
Step-by-step explanation:
You do $400÷5=80 then you do $395R4÷7=55 Then you do 55+80=$135.
so 55 adult tickets and then 80 student tickets.

Answer:
it is c
Step-by-step explanation:
with every letter there is, each letter has and is its own variable, so each factor would have its own expression not equation. with 2/5 you would have 2/5a, 2/5b, and 2/5c
i hope this helps
Answer:
Option CStep-by-step explanation:
We can tell that the variables that are multiplying the constants are a, b, and c. It is a must that 2/5 is also a factor because it is the number that is started the multiplication. Hence, the factors are 2/5, a, b, and c. This answer matches with Option C.
Hence, Option C is correct.

A scooter maintains a pace of 1.45 minutes per mile, with fuel economy of 85 miles per gallon. How many seconds can it travel on 145 mL of fuel under these conditions?
Answer:
283 seconds
Step-by-step explanation:
The computation of the number of seconds would it travel is as follows
Pace is
[tex]\frac{1.45\ minute}{mile}= \frac{87\ seconds}{mile} \\\\Fuel\ economy = \frac{85\ mile}{gallon}[/tex]
The volume of fuel = 145 ml = 0.0383 gallon
Now from 145 ml of the scooter fuel would be
= [tex]\frac{85\ mile}{gallon} \times 0.0383\ gallon[/tex]
= 3.255 mile
Now time for travel is
= [tex]\frac{87\ sec}{mile} \times 3.255\ mile\\[/tex]
= 283 seconds
The student government wants to determine the theme for the eighth-grade dance. Which group would it be best to take a sample from?
A.) student government
B.) eighth-grade students
C.) eighth-grade students in student government
D.) middle school students
The correct answer is B.) Eight-grade students
Explanation:
The purpose of a sample is to choose a reduced number of people from a specific population to study and analyze their opinions, behavior, ideas, etc. as part of a research process. Moreover, the sample or individual selected is directly related to the purposes of the research. For example, in research about the opinions of citizens about new policies, the citizens of the specific country or city should be selected.
In this context, eighth-grade students should be selected as part of the sample because this group is directly affected by the theme of the eighth-grade dance. Also, it is the interest of this group the one that determines the final theme rather than all the students or the student government.

A sandwich store charges a $10 delivery fee, and $4.50 for each sandwich
a. What is the total cost (sandwiches and delivery charge) if an office orders 6 sandwiches?
What is the total cost for x sandwiches
Answer:
$37.00
Step-by-step explanation:
The equation is: y= (4.50 * x) + 10
Plug 6 in for x: y= (4.50 * 6) + 10
4.50 * 6 = 27
27+10 = 37!

A line has this equation: x + y = 6
Write an equation for the perpendicular line that goes through (5, 1).
Answer:
the equation of the line will be: [tex]y=x-4[/tex]
Step-by-step explanation:
Equation of line: x + y = 6
We need to write an equation for the perpendicular line that goes through
(5, 1).
The equation will be in slope-intercept form [tex]y=mx+b[/tex] where m is slope and b is y-intercept
Finding Slope:
Equation of line given is: x+y=6
Writing it in slope-intercept form: [tex]y=-x+6[/tex]
The slope of this line is m = -1 (By comparing it with [tex]y=mx+b[/tex] we get m = -1)
Since the required line is perpendicular, their slopes will be opposite inverse of each other i.e. [tex]m_1=-\frac{1}{m_1}[/tex]
So, slope of required line will be: m=1
Now, using the point (5,1) and slope m=1 we can find y-intercept
[tex]y=mx+b\\1=1(5)+b\\1=5+b\\b=1-5\\b=-4[/tex]
So, we get y-intercept b = -4
Now, the equation of required line, having slope m=1 and y-intercept b = -4
[tex]y=mx+b\\y=1x-4[/tex]
So, the equation of the line will be: [tex]y=x-4[/tex]
