$50. MP3 downloads cost $1.5 each. How many songs can he download
and still have $12
Answer:
25 MP3 downloads
Step-by-step explanation:
If he starts off with $50 then these are the steps

$48.50 - $1.50 = $47.00 for 2
$48.50 - $1.50 = $45.50 for 3
then repeat that until we have $12
it doesnt give us exactly $12 but it gives us $12.50 reminder
So he can but 25 MP3 downloads and still have at least $12 remining

John uses 1 2 3 cups of milk to make a sauce recipe, and then uses 2 1 4 cups of milk to make a cake recipe. How much milk did he use in total to make the two recipes?
Answer:
3.91
Step-by-step explanation:
It is given that,
John uses [tex]1\dfrac{2}{3}[/tex] cups of milk to make a sauce recipe, and then uses [tex]2\dfrac{1}{4}[/tex] cups of milk to make a cake recipe.
We need to find how much milk did he use in total to make the two recipes. It can be calculated by simply adding [tex]1\dfrac{2}{3}[/tex] cups of milk and [tex]2\dfrac{1}{4}[/tex] cups of milk. So,
[tex]T=1\dfrac{2}{3}+2\dfrac{1}{4}\\\\=\dfrac{5}{3}+\dfrac{9}{4}\\\\=3.91[/tex]
So, she will need 3.91 units of milk to make the two recipes.

Ian's car can go 140 miles on 4 gallons of gas. During a drive last weekend, he used 5 gallons of gas. How far did he drive? Use pencil and paper. Explain how the problem changes if you were given the distance driven last weekend instead of how much gas he used.
140 miles / 4 gallons = 35 miles per gallon.
35 x 5 = 175 miles
Answer:
The car would be able to drive 175 miles with 5 gallons of gas.
Step-by-step explanation:
Every gallon of gas would give you 35 miles of distance.
To do this you divide 140 by 4 which is 35 that means 1 gallon of gas is 35 miles.
Add a extra gallon gas and also add the amount of distance the gas will give you (35 miles). Add that to 140 miles and then you get 175 miles.
For every 35 miles, I gallon of gas is used.

Determine the intercepts of the line.
x-intercept:( , )
y-intercept:( , )
Answer:
x-intercept: (-7,0)
y-intercept: (0,2)
Step-by-step explanation:
The x-intercept is (-7,0) because on the graph we can see that the line lies on the x-axis on the point (-7,0).
The y-intercept is (0,2) because we can see that the line pass through the y-axis on the (0,2) point.

The commission on the sale of a property is 5.5% of the value. What is the commission on the sale of a property that has the same percentage of the value of $21,450?
Answer: $1179.75
Step-by-step explanation:
Percentage of commission = 5.5%
Value of property = $21,450
Commission = Percentage commission × Value of property
= 5.5% × $21,450
= 5.5/100 × $21,450
= 0.055 × $21,450
= $1179.75
The commission is $1179.75

Savannah drew a map of Texas for her Geography class. According to Savannah’s map scale, one-
half inch on the map represents approximately 77.5 kilometers. If the actual distance from Austin to El
Paso is approximately 930 kilometers, what is the approximate distance
between Austin and El Paso on Savannah’s map?
Answer:
6 inches
Step-by-step explanation:
First, take the 930 kilometers and divide it by 77.5 kilometers. You will get 12. This means the distance between Austin and El Paso is 12 one half inches. That is equivalent to 6 inches.
If I deposit $ 800 in a savings account at 6% interest compounded annually, and if I make no withdrawals or deposits for 4 years, how much will I have in my account at the end of 4 years?
Answer:
$992.00
Step-by-step explanation:
Where:
I = P x r x t
P is the principal amount, $800.00.
r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 800 × 0.06 × 4 to get that:
The interest is: $192.00
Usually, now, the interest is added onto the principal to figure some new amount after 4 year(s),
or 800.00 + 192.00 = 992.00. For example:
If you borrowed the $800.00, you would now owe $992.00
If you loaned someone $800.00, you would now be due $992.00
If owned something, like a $800.00 bond, it would be worth $992.00 now.

3. It takes 200 lb of sugar cane to produce 5 lb
of refined sugar. How many pounds of sugar
cane does it take to produce 200 lb of refined
sugar?
A. 2,500 lb
B. 7,500 lb
C. 7,700 lb
D. 8,000 lb
8000 pounds is required to produce 200 lb of refined sugar
How to calculate the amount of pounds that is required to produce 200 lb of refined sugar?
It takes 200 lb of sugar cane to produce 5 lb of refined sugar
For 1 lb of sugar cane, the number of refined sugar that will be produced is
200= 5
x= 1
cross multiply
5x= 200
x= 200/5
x= 40
The number of pounds of sugar cane required to produce 200 lb of refined sugar is
= 40 × 200
= 8,000
Hence 8000 pounds of sugar cane is required to produce 200 lb of refined sugars

The Sine difference function was derivated with the help of the sine sum function.
What is the sine difference function?The difference function for the sine function states that the sine of the difference of two angles equals the product of the sine of the first angle and cosine of the second angle minus the product of the cosine of the first angle and the sine of the second angle.
As we know that
[tex]Sin(a+b) = SinaCosb + CosaSinb[/tex]..........(1)
If we replace b by -b equation (1) becomes
[tex]Sin(a+(-b)) = SinaCos(-b) + CosaSin(-b)[/tex]
We know that
Cos(-b) =cosb
Sin(-b) =-Sinb
So, [tex]Sin(a-b) = SinaCosb -CosaSinb[/tex]
Therefore, the Sine difference function was derivated with the help of the sine sum function.
