A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???
Answers
Answer:
3 : 1
Step-by-step explanation:
The ratio of coins is ...
1 2/5 : 2 1/3 = 7/5 : 7/3 = 3 : 5
The quarters have 5 times the dollar value of nickels, so the ratio of dollar values is ...
5(3) : 5 = 3 : 1
The quarters have 3 times the dollar value of the nickels.
__
Additional comment
The number of nickels is 5/3 times the number of quarters, so is 5/3(24) = 40.
The dollar value of the quarters is 24($0.25) = $6.
The dollar value of the nickels is 40($0.05) = $2.
As above, the ratio of dollar values is 6:2 = 3 : 1.

Two containers designed to hold water are side by side, both in the shape of a cylinder. Container A has a radius of 13 feet and a height of 14 feet. Container B has a radius of 10 feet and a height of 18 feet. Container A is full of water and the water is pumped into Container B until Conainter B is completely full.
After the pumping is complete, what is the volume of water remaining in Container A, to the nearest tenth of a cubic foot?
Answers
Answer:
The percentage ≅ 48.4%
Step-by-step explanation:
The volume of water left in container A = 2197π - 1134π = 1063π feet³
* To find the percentage of the water that is full after pumping
is complete, divide the volume of water left in container A
by the original volume of the container multiplied by 100
∴ The percentage = (1063π/2197π) × 100 = 48.3841 ≅ 48.4%

Shaun is painting a fence. After finishing three-eighths of the length of the fence he finds that
he has painted 15 feet. Let f be the total length of the fence, set up an equation like one of
those in 4(b) and solve to find f. Use either of the two methods.
Answers
Answer: F = 40
Step-by-step explanation:
*Important: I do not know what the methods mentioned in 4b are, nor do I know its equation. Please take this into account.
What we know:
3/8 is equal to 15 ftF is the total amount of fence paintedWe need to set up and solve the equationHow we do this:
Using basic division, this equation is solveable.
Process:
Divide to find 1/8 15/3 = 5 (1/8f = 5)Multiply to find total 5 x 8 = 40(1/8 x 8 = 8/8)
Solution:
F = 40
8(5) = F
Answer: x = 40
Step-by-step explanation:
let f be the total length of the fence:
(3/8)f = 15
divide both sides by 3/8
f = 15 x 8/3
f = 120/3
f = 40

Simplify:
-30x^9/10x^17
Answers
Answer:
-3/x^8
Step-by-step explanation:
First, we simplify -30/10 which will be -3.
Next, we simplify x^9/x^17 which will be x^-8, since when dividing exponents, you subtract them. Sorry if this sounds confusing, but if this helps you better understand it, then here you go: I mean that y^n/y^z = y^(n-z).
x^-8 = 1/(x^8), and to find our answer, we multiply this by -3 to get an answer of:
-3/x^8

• At store A, 3 pounds of apples cost $12.
• At store B, the cost is given by y = 2x where y is the cost in dollars and x is the number of pounds of apples.
• The cost of apples at store C is shown in the graph.
(don't worry about the graph I know how to do this one)
Answer the questions to find out which store's apples are the least expensive.
2. What is the unit price of apples at store B? How did you use the equation to find the unit price? (2 points)
Answers
Answer:
The unit price is the cost per unit of an item or the cost/price for each item.
1) 4$ per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.
2) 2$ per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = 2x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.
3) 3$ per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.
4) Store B. Because 2 is less than 3 which is less than 4.

Answer:
24x - 16
Step-by-step explanation
What we're doing here is factorisation
To factorise a number, you need to multiply the number outside of the bracket (in this case -4) by both of the inside numbers (-6x and 4).
First,
-4 x -6x
-4 x -6x = 24 , The x also needs to be kept- coming from the -6x, so the answer would be 24x.
You may think that because there are minuses involved, the answer would be -24x but you need to remember the rule that 2 negatives make a positive!
Next,
Multipying the outside number by the second inside again:
-4 x 4 = -16
Alongside the rule that two negatives make a postive, another rule is that one negative and one positive always result in a negative.
Finally,
Connect both of these answers
24x - 16 is the answer!
(The minus/negative symbol in the final answer is because the second multipication turned out negative, if the second number was positive, the answer would be 24x + 16.)
