Consider the situations in the table below
Situation A: A hang glider descended 33.57 feet, and then ascended 14.98 feet.
Situation B: A football team gained 7 2/5 yards in one play, and then lost 3/5 of a yard in the next play.
Situation C: A hiker walked 3 1/6 miles yesterday and 2 1/2 miles today.
Situation D: A worker earned $23.66 Monday and spent $15.84 Tuesday.
Calculate the sum of each situation. Order the situations from least to greatest based on the numeric value of the sums.
Answers
Answer:
Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet
Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.
7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.
Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.
Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

Step-by-step explanation:
If the relationships below are given in the form (input, output), which pairing always describes a function? (a person’s age in years, that same person’s height in inches) (a person’s weight in pounds, that same person’s height in inches) (a person’s height in centimeters, that same person’s height in inches) (a person’s telephone number, that same person’s height in inches)
Answers
Answer:
A function is a mathematical relation in which each input (domain value) is associated with exactly one output (range value). In other words, for a relation to be a function, each input can have only one corresponding output. Let's analyze the given pairings:
(a person’s age in years, that same person’s height in inches) - This can be a function because one person's age in years should correspond to a single height in inches.
(a person’s weight in pounds, that same person’s height in inches) - This can also be a function because one person's weight in pounds should correspond to a single height in inches.
(a person’s height in centimeters, that same person’s height in inches) - This can be a function because one person's height in centimeters should correspond to a single height in inches.
(a person’s telephone number, that same person’s height in inches) - This may not necessarily be a function. It's possible for two different people to have the same height in inches but different telephone numbers.
So, the pairings that always describe a function are:
(a person’s age in years, that same person’s height in inches)
(a person’s weight in pounds, that same person’s height in inches)
(a person’s height in centimeters, that same person’s height in inches)
These three pairings meet the criteria of a function, where each input corresponds to a unique output.
The pairing that always describes a function is option C. (a person’s height in centimeters, that same person’s height in inches)
How did we arrive at this assertion?A pairing describes a function when each unique input (domain element) is associated with exactly one unique output (range element). In other words, there should be no ambiguity or multiple outputs for a single input. Let's analyze the given pairings:
1. (a person’s age in years, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same age, but they might have different heights. So, there can be multiple outputs for the same input (age).
2. (a person’s weight in pounds, that same person’s height in inches): Similar to the first pairing, this may not always describe a function because different people can have the same weight but different heights.
3. (a person’s height in centimeters, that same person’s height in inches): This pairing describes a function because for each unique height in centimeters, there is only one corresponding height in inches.
4. (a person’s telephone number, that same person’s height in inches): This pairing may not always describe a function because multiple people can have the same telephone number, but they might have different heights. So, there can be multiple outputs for the same input (telephone number).
So, the pairing that always describes a function is: (a person’s height in centimeters, that same person’s height in inches)

Answers
Answer:
(8,1) (15,2) (22,3) (29,4) (36,5) (43,6)
Step-by-step explanation:
Answer:
Step-by-step explanation:
The equation y=7x+1 is written in slope intercept form. That would be:
y=mx+b
m is the slope
b is the y intercept, or where the line first is seen on the y axis.
Because b=1, the y intercept is 1.
Because m=7, the slope is 7.
STEP 1: GRAPH THE Y INTERCEPT.
Since b=1, the line crosses the y intercept when y=1. So graph y=1 on the coordinate plane.
STEP 2: GRAPH THE SLOPE
Do this by going up 7, then right 1. Because 7 is a positive number, you go up.

Step-by-step explanation:
To solve this, first simplify the compound expressions - the ones with multiple x, y terms and see which of the other expressions matches the simplified expression
I will tell you how to solve one of the more complex expressions; the technique is the same for the rest
Let's take the very last expression
4y + 3y + 3x - 6y -10 - 2
To simplify,
group like terms:
=(4y + 3y - 6y) + 3x +(-10 -2)
= y + 3x - 12
Rewriting with x before y gives
3x + y - 12
and there is a matching 3x + y - 12
4y + 3y + 3x - 6y -10 - 2 ⇔ 3x + y - 12

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

Answers
The median is the best measure of center because there are outliers present.
In this graph, there are some values that occur more frequently than others, which means that the data is not evenly distributed. Additionally, there are some values that are much larger than the others, such as the three dots above 3 and the single dot above 9. These values are considered outliers because they are much larger than the other values in the data set. Outliers can significantly affect the mean, making it an unreliable measure of center. Therefore, the median is a better measure of center for this data set because it is not affected by outliers.

Which fractions have a LCD of 30? A. 3/4 1/7 16 B.2/3 1/5 1/15 C. 2/15 1/4 1/3 D. 2/3 1/5 1/6
Answers
Answer:
1/5, 1/6 and 1/15
Step-by-step explanation:
Multiples of 15 are 30, 45, 60, 75, 90. Now, when you look at the list of multiples, you can see that 30 is the smallest number that appears in each list. Therefore, the least common denominator of 1/5, 1/6, and 1/15 is 30.
The fractions with LCD of 30 are D. 2/3, 1/5 and 1/6.
What is LCD?LCD, which is the abbreviated form for Least Common Denominator, is the lowest of all the common multiples of the denominators for a set of fractions.
We need to find the set of fractions with LCD as 30.
A. 3/4, 1/7 and 1/6
The denominators are 4, 7 and 6.
30 is not a multiple of 4 as well as 7.
So this set is not the answer.
B. 2/3, 1/5 and 1/15
Denominators : 3 and 5
Multiple of 3 = 3, 6, 9, 12, 15, ......
Multiples of 5 = 5, 10, 15, ......
Multiples of 15 = 15, 30, .....
15 is the LCD.
C. 2/15, 1/4 and 1/3
Denominators = 15, 4 and 3
Again 30 is not a multiple of 4.
D. 2/3, 1/5 and 1/6
Denominators = 3, 5 and 6
Multiples of 3 = 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, .......
Multiples of 5 = 5, 10, 15, 20, 25, 30, ......
Multiples of 6 = 6, 12, 18, 24, 30, .......
LCD of three fractions = 30
Hence the set of fraction is D. 2/3, 1/5 and 1/6 has LCD equals 30.
