It takes Mr. Hamilton 1/15 of an hour to grade one student’s exam and 1/30 of an hour to grade one student’s quiz.
Answer:
[tex]Total\ Time = \frac{x}{10}[/tex]
Step-by-step explanation:
Given
[tex]Exam = \frac{1}{15}hr[/tex]
[tex]Quiz = \frac{1}{30}hr[/tex]
Required
Determine the time spent on x students
First, we need to determine the total time spent on 1 student
[tex]Time = Exam + Quiz[/tex]
[tex]Time = \frac{1}{15} + \frac{1}{30}[/tex]
Take LCM
[tex]Time = \frac{2 + 1}{30}[/tex]
[tex]Time = \frac{3}{30}[/tex]
[tex]Time = \frac{1}{10}[/tex]
Next is to determine the total time on x students:
[tex]Total\ Time = \frac{1}{10} * x[/tex]
[tex]Total\ Time = \frac{x}{10}[/tex]

1. James wants to buy snacks for his friends for a movie. The cost of one box of popcorn
is $3 and the cost of one soda is $2 but James only has $15 to spend. Write and
equation to represent this situation. Remember to define the variables!
2. If James buys 3 boxes of popcorn how many sodas can he buy?
Answer:
1.) 15-3-2=x
2.) He can buy 3 sodas
Step-by-step explanation:
1.) 15 is how much he has, -3 is the price of the popcorn, -2is the price of the soda. =x is what needs to be solved in the equation (its 10 if you need the answer)
2.) He can buy 3 sodas because 3 boxes of popcorn is $9 since one box is $3, he has $15 you take away $9 and you are left with $6 and 6 divided by 2 is 3.

Write the equation of the line fully simplified slope-intercept form.I need help with this so someone please answer this .
Answer:
y= -x+6
Step-by-step explanation:
The equation format for slope-intercept form is y=mx+c, where m is the slope of the line and c is the y-intercept.
To find the slope, we need to pick two definite points and find the slope from that. The formula to find the slope is 'rise/run'. Rise is the difference between the y-values of the two points, and the run is the difference between the x-values of the two points.
Let's use the points (0,6) and (1,5).
The rise is -1 (5-6=-1) and the run is also 1 (1-0=1). This means that the slope is -1 (-1/1=-1). The slope is negative because the line is 'going downwards'.
So our equation so far is:
y=-x+c
The y-intercept is where the line crosses the y-axis and the x-value is 0. We can see from the graph that the line crosses the y-axis at the point (0,6), therefore the y-intercept is 6.
So our final equation for the line is y= -x+6.
Hope this helped!

Jason had one hundred fifty-nine dollars to spend six books.After buying them he had fifteen dollars.How much did each book cost.
Answer:
11.5
Step-by-step explanation:
Divide: 159:6-15
Calculate: 26.5-15
\\11.5//
Answer:
24.8333 with 3 repeating.
Step-by-step explanation:
Lets make an equation for this.
159 - x = 15
X is what we are loooking for so lets isolate it.
Subtract 159 on both sides.
-x = -149
Since both are negative we need to simply cross it out.
x = 149
Now he bought six books, so divide 149 by 6.
You would get 24.8333 with the 3 repeating.

Kristen invests $5,000 in a bank. The bank pays 6% interest
compounded quarterly. Find, to the nearest cent, the balance
in the account after 5 years. To the nearest year, how long
must she leave the money in the bank for it to double?
Answer:
1. ) $6,734.30
2) 12 years
Step-by-step explanation:
1. we use the compound interest formula for this
Mathematically;
A = P( 1 + r/n)^nt
where P is the principal which is the amount deposited = $5,000
r = rate = 6% = 6/100 = 0.06
n = number of time per year we compound = 4 since it is quarterly
t = number of years = 5
Substituting all of these, we have;
A = 5,000( 1 + 0.06/4)^(4)(5)
A = 5,000( 1 + 0.015)^20
A = 5,000(1.015)^20
A = $6,734.28 which to the nearest cent = $6,734.30
2) For the money to double means that A becomes 2P
Thus;
2P = P( 1 + 0.015)^4t
divide both sides by P
2 = (1.015)^4t
Fine the ln of both sides
ln 2 = 4t ln 1.015
divide both sides by ln 1.015
4t = ln 2/ ln 1.015
4t = 46.56
t = 46.56/4
t = 11.63 which is approximately 12 years
