Answer:
D) |x| = a and |y| = b
Step-by-step explanation:
Given the numbers x = a and y = –b
Absolute function always gives the output as a positive number
Absolute function of |-x|= x
For example |5|= 5 and |-5| = 5
Given x=a
|x| = |a| = a, so |x| = a
Given y=-b
|y| = |-b| = b , so |y| = b
Hence, |x| = a and |y| = b
Consider circle Y with radius 3m and central angle XYZ measuring 70degrees. What is the approximate length of minor arc XZ?

what is the distance between the points -3, 5 and -3,-9?
Answer:
the distance is 14
Step-by-step explanation:
To find the distance between 2 points, we can use the distance formula
d = sqrt( (x2-x1)^2 + (y2-y1) ^2 )
d = sqrt( (-3--3)^2 +(-9-5) ^2 )
= sqrt( (-3+3)^2 + (-14)^ 2)
= sqrt(0^2 +14^2)
= sqrt( 14^2)
= 14

You are in charge of decorating your gym for a home coming dance. You bought 6 bags of balloons and 5 bags of sparkling balloons for 19.20$. But you realize this is not enough. Than you buy 8 bags of balloons and 2 bags of sparkling stars for 15.80$. What was the price for each item
.
Answer:
I believe your answer would be 8 dollars and 75 cents. I don't know for sure.
Step-by-step explanation:
Using the provided systems of linear equations method, one bag of regular balloons costs $1.45, and one bag of sparkling balloons costs $2.10.
Explanation:The subject of this question is a typical example of a system of linear equations. Here, we are given two different purchases which give us two equations. We have:
1) 6B + 5S = 19.20 ---> Eq (1) (where B stands for one bag of balloons and S stands for one bag of sparkling balloons)
2) 8B + 2S = 15.80 ---> Eq (2)
Now, to find the prices of B and S (the number of bags of balloons and bags of sparkling balloons, respectively), we can solve this system of equations in two steps: multiplying Eq (2) by 2.5 and then subtracting Eq (1) from the result. This gives:
20B + 5S = 39.5
Then subtract Eq (1) from this new equation, which yields 14B = 20.3. So, one bag of balloons (B) costs $1.45. Substituting B = 1.45 into Eq (1), we get 6(1.45) + 5S = 19.2, which simplifies to 5S = 10.5. Thus, one bag of sparkling balloons (S) costs $2.10. So, the cost per bag of regular balloons is $1.45, and the cost per bag of sparkling balloons is $2.10, and this is how you go about decorating your gym on a budget.

Sarah feeds her fish every 2 days and her snake every 6 days. In 30 days, how many times will Sarah feed her fish and snake on the same day?
Answer:
So if sarah feeds her fish every two days, youd divide each number by 30. So the fish would be fed 15 times and the snake 5 times. Hope you get it correct! Good Luck!
Answer: hello mate!
Sara feeds her fish every 2 days: this means that if we took the 0 in a day that she feed both animals; then the fish gets food on the day 2, on the day 4, on the day 6, etc
And the snake gets food on days 6, 12, 18, etc.
now we want to count the number of days where both animals get food on the same day. Because 6 is a multiple of 2, we can see that every day that the snake is feed, the fish also feed, this is because the minimal common multiple between 2 and 6 is 6.
then we can see that each 6 days Sarah feeds her fish and snake on the same day. Now we need to see the number of times that this event happens in 30 days; we can see this dividing 30 days by 6 days:
30/6 = 5
Then in the span of 30 days, there are 5 times where both animals get food on the same day.
A rescue helicopter is used to help victims who fell in a ditch. The helicopter begins at sea level, which is an elevation of 0 feet. It then travels down for 100 seconds at a speed of 10.5 feet per second. It then travels directly up for 150 seconds at a speed of 5.2 feet per second. After this 250 second period, how much time, in seconds, will it take for the rescue helicopter to travel back to sea level at the helicopter's maximum speed of 15.8 feet per second?
Answer:
The helicopter still needs to fly up sec 17.0886 at maximum speed.

Question: Find the ratio of the width to the length of the rectangular swimming pool sketched below. Width=5.5 yards | Length=7.5 yards | Answers are: A) 11/24 yards B) 2.75/15 yards C) 15/11 yards D) 11/15 yards. Which one is it?
Answer:
D) 11/15
Step-by-step explanation:
11/15 is the doble amount of 5.5/7.5, but is the same number if you divide it.
The ratio of the width to the length of the swimming pool with a width of 5.5 yards and a length of 7.5 yards is 11/15 yards, which corresponds to answer D) 11/15 yards.
The student has asked to find the ratio of the width to the length of a rectangular swimming pool where the width is 5.5 yards and the length is 7.5 yards. To find this ratio, we divide the width by the length:
Ratio = Width / Length = 5.5 yards / 7.5 yards. Simplifying this we get:
Ratio = 11/15 yards.
Therefore, the correct answer is D) 11/15 yards.

what is the equation in plot slope form of the line that passes through the point (-1, -3) and has a slope of 4
Answer:
y+3 = 4(x+1)
Step-by-step explanation:
Point slope form of a line is
y-y1 = m(x-x1) where m is the slope and (x1,y1) is the point
y--3 = 4 (x--1)
y+3 = 4(x+1)
Answer: plot slope form is y+3= 4(x+1)
or
y = 4x+1
Step-by-step explanation:
Slope point form of equation is given by
y-y1 = m (x-x1)
where m is slope and (x1,y1) is the point
here (point) is (-1,-3) and slope = 4
so equation is
(y - (-3) )= 4 ( x -(-1))
y+3 = 4(x+1)
y+3 = 4x+4
y = 4x +1

Problem 7 is choice B, which is the entire number line shaded in but the value -4 has a hole at this location to mean "exclude this point from the solution set". So basically x can be any number but -4.
Problem 8 is choice C. You have a closed circle (or filled in hole) at -1.5 on the number line. Then you shade to the left of the closed circle to indicate the set of values that are smaller than this endpoint. So n can be -1.5 or it can be smaller than -1.5 (something like -2 or -3, etc).

Donata bought 4 lemons and 4 plums at the local supermarket for a total of $ 21.60. Dan bought 11 lemons and 6 plums at the same store for a total of $40.90 how much does one lemon cost. .... helppppp. How Much does 1 plum cost?
Answer:
Each lemon costs $1.70. Each plum costs $3.70.
Step-by-step explanation:
You have two unknowns and two statements about costs. First, define a variable for each unknown. Then, translate the statements about the costs into two equations. Then, solve the system of equations.
Let L = price of 1 lemon
Let P = price of 1 plum
Donata:
4 lemons and 4 plums for $21.60
4L + 4P = 21.6 Equation 1
Dan:
11 lemons and 6 plums for $40.90
11L + 6P = 40.9 Equation 2
Here is the system of equations.
4L + 4P = 21.6 Equation 1
11L + 6P = 40.9 Equation 2
Divide both sides of Eq. 1 by 4.
L + P = 5.4
Multiply both sides by -6.
-6L - 6P = -32.4
Add the equation above to the Eq. 2.
5L = 8.5
L = 8.5/5
L = 1.7 <------- price of a lemon
L + P = 5.4
1.7 + P = 5.4
P = 3.7 <------ price of a plum
Each lemon costs $1.70. Each plum costs $3.70.

Brad make 3 cups of pancake batter. If he needs 3/4 cup of batter to make 4 pancakes, how many pancakes can Brad make
Answer:
(3/4) cup/4 pancakes = 3 cups/x pancakes
(3/4)x = 12
x = 16
Brad can make 16 pancakes.
Brad can make 16 pancakes with 3 cups of batter, based on the ratio of 3/4 cup batter for every 4 pancakes.
To determine how many pancakes Brad can make with 3 cups of batter, when 4 pancakes require 3/4 cup of batter, we can set up a straightforward ratio and proportion calculation.
First, we divide the total batter amount by the batter requirement for a single group of pancakes: 3 cups / (3/4 cups) = 3 / 0.75 = 4 groups of pancakes.Because each group consists of 4 pancakes, we then multiply the number of groups by the number of pancakes in each group: 4 groups \\times 4 pancakes/group = 16 pancakes.Therefore, Brad can make 16 pancakes with 3 cups of batter.
What is (3x^4+2x^2-6) subtracted from (4x^4+2x^2-6)
Answer:
The answer is -x^4, Good Luck!
Step-by-step explanation:
(3x^4+2x^2-6) - (4x^4+2x^2-6) = -x^4
To subtract (3x^4+2x^2-6) from (4x^4+2x^2-6), subtract the corresponding terms and keep the same variable raised to the same power. For example, subtracting 3x^4 from 4x^4 gives us x^4. Therefore, the result is x^4.
Explanation:To subtract (3x^4+2x^2-6) from (4x^4+2x^2-6), we need to subtract the corresponding terms. So, subtract the coefficients of like terms. For the terms with variable x raised to a power, subtract the coefficients and keep the same variable raised to the same power. For the constant term, subtract the constants.
For example, subtracting 3x^4 from 4x^4 gives us (4x^4 - 3x^4) = x^4. Subtracting 2x^2 from 2x^2 gives us (2x^2 - 2x^2) = 0. Subtracting 6 from 6 gives us (6 - 6) = 0.
Therefore, the subtraction of (3x^4+2x^2-6) from (4x^4+2x^2-6) results in x^4 + 0 + 0 or simply x^4.

x cannot be larger than or even equal to 71 + 43 = 114. So it must be less than 114.But there are limits on the other end as well. 43 +x > 71, otherwise you won't have a triangle. so you have to solve that inequality as well43 + x > 71 Subtract 43 from both sides.43-43 + x > 71 - 43x > 28To put this in the form of the answer you need it looks like this.28 < x < 114A store is having a sale on liquid soap and sponges. The cost of 6 bottles of soap is $9.12. The cost of 4 sponges is $5.00 what is the total cost of buying 2 bottles of liquid soap and 3 sponges
Answer:
$6.79
Step-by-step explanation:
We need to find the cost of a bottle of soap. We divide the cost by the number of bottles
$9.12/6 = $1.52 per bottle
We also need to find the cost for a sponge
$5.00/4 = $1.25 per sponge
We want to find the total cost of 2 bottles of soap and 3 sponges
cost = 2 * 1.52 + 3 * 1.25
= 3.04 + 3.75
= 6.79
Final answer:
The total cost comes to $6.79.
Explanation:
To calculate the total cost of buying 2 bottles of liquid soap and 3 sponges, we need to first find the cost of a single bottle of soap and a single sponge. We can do this by dividing the total cost of multiple items by the number of items to get the price per item.
The cost of 6 bottles of soap is $9.12. To find the cost of 1 bottle of soap, we divide: $9.12 / 6 = $1.52 per bottle.
The cost of 4 sponges is $5.00. To find the cost of 1 sponge, we divide: $5.00 / 4 = $1.25 per sponge.
Now, we can calculate the cost of 2 bottles of soap: 2 x $1.52 = $3.04.
And the cost of 3 sponges: 3 x $1.25 = $3.75.
Finally, we add the two amounts to find the total cost: $3.04 (soap) + $3.75 (sponges) = $6.79
So, the total cost of buying 2 bottles of soap and 3 sponges is $6.79.
