Answer:
At the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F
Step-by-step explanation:
At 502.5 feet below the sea level temperature of the water is 63\frac{1}{4}°F
When submarine dives down 115 feet deeper, water temperature drops by 2\frac{1}{5}°F
Elevation after the submarine dove = -502.5 - 115 = -617.5 feet
This negative sign represents the elevation below the sea level.
And the temperature will be = 63\frac{1}{4}-2\frac{1}{5}
= \frac{253}{4}-\frac{11}{5}
= \frac{1265-44}{20}
= \frac{1221}{20}
= 61\frac{1}{20}°F
Therefore, at the elevation 617.5 feet below the sea level temperature of the water was 61\frac{1}{20}°F
The required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.
A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F.
It is the relationship between sets of values. e g y=f(x),
Here, assume that relation ship between temperature and sea level is linear. So the expression can be calculated as y = - 0.01x + 58.2.
Since at 115 feet deeper from 502.5 temperature-
total sea level; = 502.5+115
= 617.5
Put it in expression
y = -0.01 * 617.5 + 68.2
y = 61.25
y = 61 1/4 °F
Thus, the required expression is y = 0.01x + 58.2. Where, x = level of sea and y = temperature. At 115 feet deeper temperature is 61 1/4°F.

Use the data in the table to find the rate of change in the length of baby girl Grace. (2 points)
Answer: Baby Girl Grace grows 3/4 inch every month.
Step-by-step explanation:
Y= (y_2 - y_1)/ (x_2 - x_1)
Y= (29-26)/(16-12)
Y= (3/4)
The rate of change of height of baby girl is 0.75 inches per month.
What is Rate of change?A value that results from dividing the change in a function of a variable by the change in the variable velocity is the rate of change in distance with respect to time.
Here, from the given table;
At 4th month, the length of baby girl = 20 inches
at 30th month, the length of baby girl = 39.5 inches
x₁ = 4, y₁ = 20
x₂ = 30 y₂ = 39.5
Now,
Rate of change of height = (y₂-y₁) / (x₂ - x₁)
= (39.5 - 20) / (30 - 4)
= 19.5 / 26
= 0.75
Thus, the rate of change of height of baby girl is 0.75 inches per month.

A ribbon is 5 4/5 yards long. Mae needs to cut the ribbon into pieces that are 4/5 of a yard long. How many pieces of ribbon can she cut?
The answer is 7 pieces.
If you divide 5.80 (5 4/5) by 0.80 (4/5), you get 7.25. Since Mae probably doesn't want to use a piece of ribbon smaller than the others she will only cut 7 pieces.
Answer:
7
Step-by-step explanation
5 4/5 = 5/5, 5/5, 5/5, 5/5, 5/5, 4/5
so five 5/5 - 1/5 each = 4/5, 4/5, 4/5, 4/5, 4/5 so we now have five 4/5 + the 4/5 we had at the beginning so we have six 4/5 then add all of the 1/5 we took away from all of the 5/5 so 1/5 x 5 = 5/5 = 4/5 Remainder 1/5 so we now have seven 4/5 and an extra 1/5
so, in conclusion, Mae can cut seven pieces of ribbon.

Serena is building a bookcase. She cuts two pieces of wood from one board. One piece is 1 7/8 feet long and another is 3 1/2 feet long. What is the total change in the length of the original board?
Answer:
43/8 feet
Step-by-step explanation:
The total change is the sum of the length of two boards she cut.
First board length is 1 7/8th feet. Let's change to improper fraction:
1 7/8 = 15/8 feet
Second board lengrh is 3.5 feet, or 3 1/2 feet. Let's change to improper fraction:
3 1/2 = 7/2 feet
Let's add the two:
The change in original board is 43/8 feet

What are the domain and range of the representative function?
A)Domain: 0 ≤ x ≤ 4
Range: 0 ≤ y ≤ 80
B)Domain: 0 < x < 80
Range: 0 < y < 4
C)Domain: 0 < x < 4
Range: 0 < y < 80
D)Domain: 0 ≤ x ≤ 80
Range: 0 ≤ y ≤ 4
Answer:
It´s A
Step-by-step explanation:
You can eliminate B and D because the ¨x¨ would be 4 not 80 because it´s on the x-axis not on the y-axis. Secondly whenever you have a graph you need to have the less than or equal to sign with the line under.
Hope this helps :)
The domain and range of the representative function should be option A. Domain: 0 ≤ x ≤ 4
Range: 0 ≤ y ≤ 80
What are domain and range?The domain of a function represent the set of values that should be permitted for putting into the function. In this set, the x values in the function like f(x). Here the range of the function represent the amount set where the function should be presumed.
Therefore, based on the given graph the correct option is A.

SLOPE INTERCEPT FORM:
y = 1x-5
The equation of line is y = 1 x + ( -5 )
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept.
And y - y₁ = m ( x - x₁ )
y = y coordinate of second point
y₁ = y coordinate of point one
m = slope
x = x coordinate of second point
x₁ = x coordinate of point one
Given data ,
y intercept b = - 5
Slope m = Rise / Run
= 5 / 5
= 1
The equation of line is y = mx + b
Therefore , y = x - 5
