Answer:
→ Distance run by dean = 6.8 km .
also,
→ Distance run by dean = 2.3 fewer kilometers than Sam.
Let us assume that, distance run by same is s km .
so,
→ Distance run by dean = s - 2.3
therefore,
→ s - 2.3 = 6.8
→ s = 6.8 + 2.3
→ s = 9.1 km .
Hence, The correct equation is s – 2.3 = 6.8

An arc of circle M has a length of 32π centimeters and the corresponding central angle has a radian measure of 8/9π. What is the radius of the circle?
Answer:
36 cm
Step-by-step explanation:
arc length = r × θ
32π = r × 8/9π
r = 36
The radius of the circle is 36 centimeters when the arc length is 32 centimeters and the corresponding central angle is (8/9)π radians.
What is an arc of the circle?A circle's arc is defined as a portion or segment of its circumference.
How is the length of an arc calculated?The length of an arc, s. of a circle having a radius r, with the central angle θ, is given as s = rθ.
How to solve the question?In the question, we are given an arc of a circle having a length (s) = 32π centimeters, and the corresponding central angle (θ) = (8/9)π radians.
We are asked to find the radius (r) of the circle.
We know that the arc length is the product of the radius and the central angle, that is, s = rθ.
Following this, we can write:
32π = r(8/9)π,
or, r = (32π*9)/(8π) = 36.
Therefore, the radius of the circle is 36 centimeters.

Explanation:
The key thing to focus on is the phrasing "starting at the age of 8"
Specifically, your teacher wants the starting height when Mia was 8 years old. That height being 52 inches.
The 7 inches refers to how much she had grown over the 2 years, which is part of the rate of change (and will be part of the slope).
Side note: 52 inches = 4 ft, 4 inches
You have 3 red, 4 blue and 5 yellow marbles. What is the probability of not picking blue?
This is because there are 3 red + 5 yellow = 8 non-blue marbles out of 3+4+5 = 12 total. This leads to the fraction 8/12 and it reduces to 2/3.

Step-by-step explanation:
Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, HCF). When graphed, the function gives a line with a slope of 1.45. See the figure below.
If the monthly cost for 13 HCF is $46.33, what is the monthly cost for 17 HCF?
The monthly cost for 17 hundred of cubic feet is $52.13.
What is a linear equation?A linear equation is in the form:
y = mx + b
Where y,x are variables, m is the rate of change and b is the initial value of y.
Let y represent the bill paid for x HCF of water.
The slope is 1.45, hence m = 1.45.
The monthly cost for 13 HCF is $46.33, hence:
46.33 = 1.45(13) + b
b = 27.48
y = 1.45x + 27.48
For 17 HCF:
y = 1.45(17) + 27.48 = 52.13
The monthly cost for 17 hundred of cubic feet is $52.13.

Add 5 to both sides
4 + 5 + 3y = 6y
9 + 3y = 6y
Subtract 3y to both sides
9 = 6y - 3y
9 = 3y
Divide 3 to both sides
3 = y
