Answer:
Mixed number: [tex]3\frac{15}{100}[/tex]
Improper fraction: [tex]\frac{315}{100}[/tex]
Step-by-step explanation:
A mixed number is a number that contains an integer part and a fraction part.
An improper fraction is a fraction where the numerator is greater than the denominator.
[tex]3.15[/tex] can be written as [tex]\frac{315}{100}[/tex] in its fraction form. This would be an improper fraction since the numerator is greater than the denominator.
The mixed number is [tex]3\frac{15}{100}[/tex] since [tex]100[/tex] goes into [tex]315[/tex] three full times and the remainder is [tex]15[/tex].
∴The mixed number is [tex]3\frac{15}{100}[/tex] and the improper fraction is [tex]\frac{315}{100}[/tex].

Step-by-step explanation:
when p(n)=c(n), the cost equals the sales
15n+60=30n
60=15n
n=4

Jamal has a plan to save money for a trip. Today, Jamal deposits $10.00 into the savings account. Each week, Jamal will add $5.00 to the amount that is deposited into the savings account. The table below shows the relationship between the number of weeks and how much money, in dollars, Jamal deposits into the savings account.
Let f(x)represent the amount of money Jamal deposits into his savings account at the end of x weeks. Based on the table, what is f(10)?
Answer:
y = 5x + 10
Step-by-step explanation:
using the formula y = mx + b you can easily find the answer.
where
m = the rate of change
b = constant
x = the independent variable
Since he has the initial $10.00 added to the account, we know that is the constant since he won’t be adding that anymore.
Since he will be adding $5.00 to the account every month we know that this is the rate of change.
the variable x will change depending on the number of months passed.
Therefore we can create the equation:
y = 5x + 10

Answer:
C
Step-by-step explanation:
16 : 12
x : 6
- multiply 16*6 and divide by the number multiplying with the unknown (12)
(16*6)/12 = 8
- area of triangle is 1/2 h*b
so 1/2 * (16*8) = 64

Answer:
I was never good at this in math...
Answer:
X = 30
Y = 14
Step-by-step explanation:
x/20 = 18/12
multiply both sides by 20
x = 18/12 x 20 = 30
y/21 = 12/18
multiply both sides by 21
y = 12/18 x 21 = 14

What is the slope of a line parallel the the line whose equation is x+y=5. Fully reduce your answer.
Answer:
m = -1
Step-by-step explanation:
Find the slope of this line.
x+y=5
y= (-1)x+5
Slope (m) = -1 <-- from y = mx+b
A line parallel to the line will have the slope -1.

Suppose you earned a $555,000 bonus this year and invested it at 8.25% per year. How much could you withdraw
years?
Select the correct answer.
a. $57,592.18
b. $57,500.68
c. $57,575.18
d. $57,609.18
e. $57,583.68
Answer:
Annual withdraw= $57,583.68
Step-by-step explanation:
Giving the following information:
Present Value (PV)= $555,000
Interest rate (i)= 0.0825
Number of periods (n)= 20
To calculate the annual withdrawals, we need to use the following formula:
Annual withdraw= (PV*i) / [1 - (1+i)^(-n)]
Annual withdraw= (555,000*0.0825) / [1 - (1.0825^-20)]
Annual withdraw= $57,583.68

Find the solution to the equation
16.2 + n = 16
Answer:
-0.2
Step-by-step explanation:
to find n you need to get it all by itself so you subtract 16.2 from both sides so on the left side it cancels out and on the right side it equals -.02 which is then equal to n which is your answer
A restaurant sells 6 tacos for $5.40. What is the unit rate?

The lines represented by the equations 20y−24x=−20 and 5y−6x=−5 are...
a)perpendicular
b)the same line
c)neither parallel nor perpendicular
d)parallel
Answer:
parallel i think
Step-by-step explanation:
parallel because it's a unknown error
Answer:
Choice B
Step-by-step explanation:
The best way to compare two lines is to solve for y.
The first equation:
For [tex]20y-24x=-20[/tex] the first thing we should do is add the 24x on both sides which will cancel out itself on the left side [tex]20y=24x-20[/tex]. Now all we have to do is divide the 20 on both sides to leave us with [tex]y=\frac{6}{5}-1[/tex].
The second equation:
For [tex]5y-6x=-5[/tex] the first thing we should do is add the 6x on both side which will cancel itself on the left side [tex]5y=6x-5[/tex]. Now all we have to do is divide the 5 on both sides to leave us with [tex]y=\frac{6}{5}x-1[/tex].
Now for the comparison:
They are the same exact line. If you were to graph them they would overlap each other.
