A store sells jump ropes. Each jump rope costs the same amount. During a sale, the store reduces the prize of each jump rope by $1.90. Marc spends $12.78 on 2 jump ropes at the sale price. What was the price of 1 jump rope before the sale?
Answer:
Each price was 2.59
Step-by-step explanation: If you want to know the price for each jump rope and there are 2 of them you divide 12.78 by 2 =6.39. However during the sale the reduced the price by 1.90, but there are 2 jump ropes so I added 1.90 by 1.90 = 3.80. 6.39- 3.80 = 2.59.
Answer:
2.59

Find the approximate perimeter of rectangle ABCD plotted below.
B(4,5)
A(-6,0)
C(8, -3)
D(-2, -8)
Answer:
The answer is 40.2
The approximate perimeter of the rectangle ABCD plotted below is 40.24 units.
The given coordinates are B(4,5), A(-6,0), C(8, -3) and D(-2, -8).
We need to find the perimeter of the rectangle ABCD by plotting the coordinates on the graph.
What is the formula to find the perimeter of the rectangle?The formula to find the perimeter of the rectangle is 2(Length+Breadth).
By using the distance formula find the length and breadth of a rectangle.
That is Distance = [tex]\sqrt{(x_{2}-x_{1} )^{2} -(y_{2}-y_{1} )^{2}}[/tex] units.
Now, AB=[tex]\sqrt{(4+6)^{2}+(5-0)^{2} } =\sqrt{125}[/tex]=11.18 units
BC=[tex]\sqrt{(8-4)^{2}+(-3-5)^{2} } =\sqrt{80}[/tex]=8.94 units
Now, Perimeter=2(11.18+8.94)=40.24 units
Therefore, the approximate perimeter of the rectangle ABCD plotted below is 40.24 units.

farmer has 30 animals with 66 legs how many cows and chichkens
Answer:
27 Chickens and 3 Cows.
Step-by-step explanation:
27*2=54 (chickens), 3*4=12 (cows), 54+12=66.
Answer:
3 cows and 27 chickens?
Step-by-step explanation:
x is the number of cows and y is the number of chicken
x + y = 30
cow has 4 legs and chicken has 2 legs therefore
4x + 2y = 66
simultaneously,
x + y = 30 ⇒ x = 30 - y
substitute x = 30 - y in 4x + 2y = 66
4(30 - y) + 2y = 66
120 - 4y + 2y = 66
120 - 2y = 66
-2y = 66-120
-2y = -54
y = -54/-2
y = 27
x = 30 - 27
x = 3

1) Diego measured the number of cups of water in 15 bottles of various sizes. He
made this line plot to show how many of each size he has. Diego then took all
the bottles of the most common size and poured the water into one container.
How much water is in the container?
Bottle Sizes in Cups
Answer:
[tex] 8\frac{3}{4} [/tex] cups.
Step-by-step explanation:
From the line plot made by Diego which represents bottle sizes in cups, we can see that the most common size is the bottle having 1¾ cups (there are 5 of this sizes).
If he poured all 5 of this bottle sizes in 1 container, he would have the following:
[tex] 1\frac{3}{4} * 5 = \frac{7}{4}*5 = \frac{35}{4} [/tex]
[tex] = 8\frac{3}{4} [/tex] cups.

11.) Sam has a total of 45 dimes and nickels. The number of dimes she has is 3 more than twice the number of nickels. How many of each coins does she have? How much money does she have altogether?
Answer:
Number of nickels: 14
Number of dimes: 31
Total money: $3.80
Step-by-step explanation:
Let number of nickels be x
Number of dimes is 2x+3
Total coins = 45
So add the number of nickels and dimes and it equals 45
x+2x+3=45
3x=45-3=42
x=42/3=14 nickels
Substitute the value of x=14 in 2x+3 to find number of dimes
2(14)+3=28+3=31 dimes
Total money is 14 nickels + 31 dimes
Nickels = 0.05 and dimes is 0.10
14(0.05)+31(0.10)=0.7+3.1=3.8

Using the Law of Detachment if a polynomial is prime, then it cannot be factored. 5x+13y is prime.
Answer and Step-by-step explanation: Law of deduction is a mathematical logic that states the following:
1) If p happens, then q happens;
2) p is true;
Then, a there is a third statement that is
3) q is also true.
In this question,
If a polynomial is prime, then it cannot be factored.
Statement p is that 5x + 13y is a polynomial and is prime, i.e., p is true.
Statement q is that "it cannot be factored"
Therefore, 5x + 13y cannot be factored.
The law of detachment is used to confirm or refute a claim.
The true statement is: 5x + 13y cannot be factored
The law of detachment states that; for statements p and q
(1) If p then q
(2) p
If the above statements are true, then the following statement is true
(3) q
The statements in the question can be represented as:
(1) If 5x + 3y is a polynomial and is prime then it cannot be factored
(2) It cannot be factored
Using the above representations of p and q, as an illustration; the third statement would be:
(3) 5x + 3y is a polynomial and is prime
Since the third statement is true, then we can conclude that
5x + 13y cannot be factored

Susan told her friend about an amazing new product. Her friend told 2 of her friends about it. If each person tells 2 people about the product, how many people will find out about it after 10 days?
Answer: If each person tells 2 people each day, 1,024 people will know in 10 days.
Step-by-step explanation: Basically it is 2 to the 10th power. It is 2 to the 10th power because in 10 days 2 people each day are getting told this information and those same 2 people spread this information. So if 2 people each day for 10 days tell people about the product, 1,024 will know by the tenth day.
