Answer:
1
Step-by-step explanation:
to find the slope you want to put the values into this equation:
(y value 1 - y value 2)/(x value 1 - x value 2)
so we get
(5-7)/(2-4)
= -2/-2
=1

Which expression represents –3.2t(4t + 6.5)?
Answer:
[tex]-12.8x^{2} -20.8t[/tex]
Step-by-step explanation:
[tex]-3.2t*4t=-12.8x^{2}[/tex][tex]-3.2t*6.5=-20.8t[/tex][tex]-12.8x^{2} -20.8t[/tex]The original price for an item is $95, the sale price is $61.75. What is the discount?
Answer:
To find the discount on an item, you need to subtract the sale price from the original price and then multiply the result by 100 to express it as a percentage. In this case, the discount would be calculated like this:
Discount = (Original price - Sale price) * 100
Plugging in the prices from the question, we get:
Discount = (95 - 61.75) * 100 = 33.25 * 100 = 3325%
So, the discount on the item is 3325%. This means that the item is being sold for 33.25% less than its original price.
Step-by-step explanation:
Answer: 35%
Step-by-step explanation:
95 - 61.75 = 33.25
33.25 : 95 = 0.35 = 35 %

Answer:
c<10 --------> The bag contains fewer than 10 carrots
c>10 ---------> Catherine biked farther than 10 miles
c<20 ---------> The chair is shorter than 20 inches
c>20 ----------> Carlos scored over 20 goals.
Step-by-step explanation:
C is less than 10 so there had to be fewer than 10. So there are less that 10 carrots in the bag.
C is greater than 10 so there has to be more than 10. So she biked more than/farther than 10 miles.
C is less than 20 so there has to be less than 20. So the chair is shorter/less than 20 inches.
C is greater than 20 so there has to be more than 20. So carlos scored over/more than 20 goals.

Recall that rational numbers are numbers that can be represented as the ratio, or fraction, of two integers. When expressed as decimals, rational numbers either terminate or repeat. For the following rational numbers, use long division to rewrite each fraction as a decimal number. Then, classify each decimal equivalent as terminating or repeating.
division to rewrite each fraction as a decimal number. Then, classify each decimal equivalent as terminating or repeating.
5 2/7 repeating or terminating
7/16 repeating or terminating
14 5/9 repeating or terminating
3/22 repeating or terminating
Answer:
Repeating
Terminating
Repeating
Repeating
Step-by-step explanation:
5 2/7 as improper fraction is 37/7 and it equals 5.28571428571 which makes it repeating because the numbers don't stop.
7/16 is equal to 0.4375 making it terminate because the numbers stop.
14 5/9 as an improper fraction is 131/9 and 131/9 is 14.5555555556 and that is a never ending pattern so it is repeating.
3/22 is equal to 0.13636363636 it is repeating because the numbers never stop.

The equation c = 5m represents how many ice cream cones (c) are sold within a certain number of minutes (m) at a certain ice cream shop.
Determine the constant of proportionality.
5
1
one fifth
25
Answer:
The COP of problem is 5 because the 5m means 5 per minute, which means that the cop is 5.
Answer: 5
Step-by-step explanation:
The constant of proportionality is 5 because here is the formula for this sort of question.
y=kx The k is the constant of proportionality and we can substitute the k for 5.
Ok, maybe that wasn't very helpful but the simplest way to know is this.
The 5 is the constant of proportionality because the constant of proportionality is the same thing as the slope (hopefully you know what slope is). The slope is the rate of change.
C is the y because the number of cones DEPENDS on the number of minutes (the number of minutes is X). The number of cones change by each minute.
Example:
c=5(3)
c=15 (15 cones)
or
10=5x
10/5=5x/5
2=x
Just use substitution.
Okay sorry if this was confusing, I just am not good at explaining this even though I know what it is.
Simple answer: It's 5

Step-by-step explanation:
There are nine water bottles in Devin's refrigerator. He adds three full boxes of water bottles to the refrigerator. Then he adds two more boxes that each has 1 fewer bottle than a full box. When he is done, there are 67 bottles in the refrigerator. Write and solve an equation to find the number of bottles in a full box.
Answer:
12
Step-by-step explanation:
let x be 1 full box
9 + 3x + 2(x -1) = 67
67 - 9 = 58
3x + 2(x -1) = 58
expand 2 into the bracket
3x + 2x - 2 = 58
5x = 60
x = 12
Answer:
9+3x+2(x-1)=67
x=12
Step-by-step explanation:
So we have 9 water bottles, so we put that as 9 in our equation. Then he adds 3 full boxes of water bottles, but we don't know how many water bottles are in each box, so we would label that as x, so it would be 3x. Then he adds two more boxes that each has 1 fewer bottles than a full box, so that would be 2(x-1) because we know that each box has x amount of water bottles, and you just subtract one, and we also know that we have 2 of those boxes. Then, when he is done, that means the whole equation equals, 67. Our equation would be 9+3x+2(x-1)=67. Now we solve for x.
9+3x+2x-2=67
9+5x-2=67
9-2+5x=67
7+5x=67
5x=60
x=60/5
x=12

To solve for the value of "a", we'll need to use the Pythagorean Theorem.
Pythagorean Theorem: a^2 + b^2 = c^2
---a and b are the legs of the triangle and c is the hypotenuse
Plug in known values and simplify:
a^2 + (9)^2 = (12)^2
a^2 + 81 = 144
a^2 = 63
a = sqrt(63)
The number that should go beneath the radical symbol is 63.
Hope this helps!

(Multi-Step Percent Problems HC) Predict the cost of a meal for a family of four between $50 and $100. Be sure to include dollars and cents. Part A: If the family has a 20% off coupon, calculate the new price of the meal. Show all work or explain your steps. (6 points) Part B: Calculate a 20% tip using the new price. What is the final cost of the meal? Show all work or explain your steps. (6 points)
Answer:
Part A: To find the cost of a meal for a family of four between $50 and $100, we need to pick a number within that range. Let's assume that the meal costs $75. If the family has a 20% off coupon, we need to multiply the cost of the meal by 20% to find the discount. This gives us $75 * 20% = $15. Therefore, the new price of the meal after the discount is $75 - $15 = $60.
Part B: To calculate a 20% tip using the new price, we need to multiply the new price by 20%. This gives us $60 * 20% = $12. Therefore, the final cost of the meal with the tip included is $60 + $12 = $72.
