Express your answer as a mixed number in simplest form.
Answers
October: 8 3/8 inches
September : 60% less rain fell than in October.
This means that only 40% rain fell in September based on the amount of rain that fell in October.
8 3/8 ⇒ (8*8)+3/8 = 67/8
40% is 4/10
67/8 * 4/10 = 268/80 = 3 28/80 or 3 7/20 or 3.35
28 ÷ 2 = 14
80 ÷ 2 = 40
14 ÷ 2 = 7
40 ÷ 2 = 20
In September 3 7/20 inches or 3.35 inches of rain fell.
60% of 8 3/8 in. = 60% * 8 3/8 = 60/100 * 67/8 = 201/40 = 5 1/40 in.
8 3/8 - 5 1/40 = 67/8 - 201/40 = 67/20 = 3 7/20 in.
The correct result would be 3 7/20 in.

If we graph this there will be 3 segments because the slope of each segment is Keisha's speed during that interval:
⇒ The middle segment will have no slope,which makes the slope undefined.
⇒ The 1st and 3rd segments will have positive slopes, If a line has a positive slope, variable y always increases when x increases.
Choice A). A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 5, decreases to 0.25 comma 2, stays horizontal to 0.6 comma 2, then increases to 0.75 comma 9. The line is horizontal to 1.75 comma 9.
The given graph started that the time is 0, when Keisha begins
running. she is already 5 blocks from home. So this data is incorrect. The graph also states that the line decreases,when she runs toward her home.
Terrible choice.
Choice B). A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 0, increases to 0.3 comma 2, increases to 0.5 comma 5, then increases to 0.75 comma 9. The line decreases to 1.75 comma 0, where it touches the axis.
Terrible choice.
Choice C). This is the correct answer. It includes all the information that appears on the given graph, and it matches the given story.
Choice D). A coordinate plane graph is shown. The axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 5, is horizontal to 0.3 comma 5, increases to 0.5 comma 6, is horizontal to 0.8 comma 6, then increases to 1.75 comma 9
Terrible choice.
Part 2 : Sasha withdrew spending money. Meaning : To remove (money) from an account.
The correct answer is the last one.
Answer:
A coordinate plane graph is shown. The x-axis is labeled time and the y-axis is labeled distance from home in blocks. A line begins at 0 comma 0, increases to 0.25 comma 5, stays horizontal until 0.5 comma 5, then increases to 0.75 comma 9. The line is horizontal until 1.75 comma 9.
Explanation:
First segment: distance and time increases (Keisha ran to Natasha's house)
Second segment: time increases, distance is constans (Keisha stayed at Natasha’s house)
Third segment: distance and time increases (Keisha and Natasha ran to swim practice)
Fourth segment: distance is constans, time increases (Keisha and Natasha stayed on practice).
Q2.
Answer:
Sasha did not withdraw or deposit any money. (During 5 days of the account balance has not changed).

Divide both sides by 4:
x^2 + 5 x + 25/4 = 7/4
Write the left-hand side as a square:
(x + 5/2)^2 = 7/4
Take the square root of both sides:
x + 5/2 = sqrt(7)/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
x = sqrt(7)/2 - 5/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
Answer: x = sqrt(7)/2 - 5/2 or x = -5/2 - sqrt(7)/2

Option 1st is correct
area of a triangle is, 80 in²
Step-by-step explanation:
Area of triangle(A) is given by:
where,
b is the base
h is the height or altitude of the triangle respectively.
As per the statement:
Base of a triangle(b) = 10 inches and
Height = altitude(h) = 16 inches
Substitute these in [1] we get:
⇒in²
Therefore, the area of a triangle is, 80 in²
160 / 2 = 80
Your answer would be 80in²
Hope that helps!

The specified formula y = (x-1)(4x+2)A linear function, -4x² has a constant term of -2 and a linear term of 2x.
To determine whether the function y = (x-1)(4x+2)-4x^2 is linear or quadratic, we can analyze the equation and identify its terms.
Start with the equation:
y = (x-1)(4x+2)-4x²
Expand the equation by multiplying the terms:
y = 4x² + 2x - 4x - 2 - 4x²
Simplifying further,
y = 2x - 2.
Analyzing the equation, we can see that there is no x² term. This indicates that the function is linear.
Let's identify the terms of the equation:
Quadratic term: There is no x² term in the equation.
Linear term: The linear term is 2x.
Constant term: The constant term is -2.
Therefore, the given function y = (x-1)(4x+2)-4x² is a linear function with a linear term of 2x and a constant term of -2.

Multiplying (x-1) by (4x+2) the term in x² is x*4x=4x².
If we substract 4x² the term of y in x² will be 0.
The function is not quadratic.
Since 4x*(-1)+2*x=-2x (product of terms in x) : the function is thus linear.
Constant term is -1*2=-2

Answer:
The diameter is 32.04 Inches
Step-by-step explanation:
If the Bicycle makes 5 rotations and it equals 41.87 ft
Then 1 rotation around the circumference is
41.87/5 = 8.374 ft
Circumference =
8.374 = 3.14*d
Divide both sides by 3.14
d = 8.374/3.14
d = 2.67 ft
To convert feet to inches, we multiply by 12
d = 2.67*12 inches
d = 32.04 Inches
