11. A scuba diver's elevation changed by -123 feet every minute. This was
1½ times the rate of change for a second scuba diver. What was the rate of
change in elevation of the second scuba diver in feet per minute?
Answers
Answer:
The rate of change in elevation for the second scuba diver is -82 feet per minute.
Step-by-step explanation:
-123 feet every minute.
1.5x more than 2nd diver.
-123/1.5 = 2nd diver rate
2nd diver rate = -82
The rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.
Given that, a scuba diver's elevation changed by -123 feet every minute.
What is constant rate of change?When something has a constant rate of change, one quantity changes in relation to the other. For example, for every half hour the pigeon flies, he can cover a distance of 25 miles. We can write this constant rate as a ratio. For ratios, it's always a good idea to state both units in whole terms.
1½=1.5 times the rate of change for a second scuba diver
Now, rate of change in elevation of the second scuba diver
= -123/1.5
= -82 feet per second
Hence, the rate of change in elevation of the second scuba diver in feet per minute is -82 feet per second.

Step-by-step explanation:
First we add the similar parts of the expression.
Whole numbers
6 + 9 + 5 + 7 = 27
Then we add the fractions that dont have x.
We only add the numerators (2 and 3) and dont change the denominators (4)
2/4 + 3/4 = 5/4
Now we add the ones with x.
5/4 + 3/4x + 3/4x = 11/4x

Answer:
Required Expression : 7·(s + d) - 25
Step-by-step explanation :
Cost of each plant both buys = $7
No. of plants Stephanie wants to buy = s
Total cost of plants bought by Stephanie = 7·s
No. of plants Diego wants to buy = d
Total cost of plants bought by Diego = 7·d
Total cost = 7·s + 7·d
= 7·(s + d)
Discount applied through coupon = $25
So, Total cost of all their plants with discount = 7·(s + d) - 25

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

The ordered pairs below represent a linear function.
(3/4, 6 1/4), (1 1/4, 7 3/4), (x, y)
Which values could be the value of x and y?
Answers
Answer:
x can be any real number, and y is the corresponding number according to the function y=3x+4
Step-by-step explanation:
We find the function first, by finding the slope.
Using this formula, m= (y1-y2)/(x1-x2)
= (31/4 - 25/4)/(5/4 - 3/4) = 3/2÷1/2 = 3
Now we can find the y-intercept by substituting it as b, and x and y as one of the points.
y=mx+b
25/4=9/4+b
b=4
And now you fill out the format, y=mx+b with your newfound values of m and b,
y=3x+4
From this function, you can input any real number (x) and get your corresponding value (y).

Ten mangos and twelve avocadoes cost $23. Five mangos and four avocadoes cost $10. How much do one mango and one avocado cost?
Answers
Answer:
$2.15
Step-by-step explanation:
Let mango be m
Let avocado be a
10m + 12a = 23
5m + 4a = 10
Let's get rid of the mangos in the second equation
10m + 12a = 23
-2 x (5m + 4a = 10)
Now we get:
10m + 12a =23
-10m -8a = -20
Add both the equations and we get:
4a = 3
a = $0.75
since we know that one avocado is for $0.75, we can use this value to find the cost of one mango.
5m + 4a = 10
5m + 4(0.75) = 10
5m + 3 = 10
5m = 7
m = 1.4
So, we now know that a mango cost $1.4
To find the cost of one mango and one avocado:
a + m = 0.75 + 1.4 = 2.15
Therefore, the cost of one mango and one avocado is $2.15
The required cost of one mango is 1.4 and cost of one avocado is 0.75.
What is an equation ?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
Cost of ten mangos and twelve avocados is $23,
And cost of five mangos and four avocados is $10.
Let cost of mangoes be represented as M and cost of avocados be represented as A,
The equation can be written as,
10 M + 12 A = 23 (1)
5 M + 4 A = 10 (2)
By solving equation (1) and (2),
M = 7/5 = 1.4
N = 3/4 = 0.75
The cost of one mango is 1.4 and cost of one avocado is 0.75.

Westin performed an experiment in which he randomly pulled a marble from a bag, recorded its color, put it back, and then repeated. He did this 36 times, and 9 of those times he pulled a purple marble.

A ) 4 purple, 5 blue, 2 green, 1 red
B ) 4 purple, 5 blue, 2 green, 1 red
C ) 9 purple, 9 red, 9 green
D ) 9 purple, 9 red, 9 green

F ) 1 purple, 1 blue, 1 green, 1 red
G ) 4 purple, 4 blue, 4 yellow, 4 orange
Answers
Answer:
Step-by-step explanation:
Based on the experiment, 9 times he pulled a purple marble out of the 36 trials.
That means he has a 1/4 probability of pulling a purple marble
This means that the purple marble ideally makes up one-quarter of the total marble in the bag.
Choice G and F satisfy the condition as stated above.
