The head track coach for PCTVS has a big track meet coming up. He knows that his biggest rival is Clifton and the entire track meet will come down to one event, the 100 meter relay race. The relay race is comprised of 4 runners from each team who run 100 meters each. The track coach has been working on his projections for the race and knows it will come down to the last leg of the race. He is having difficulty with his algebra skills, so he has asked the Honors classes at PCTI to help him make a projection for the race. He knows that on the last leg of the race, his runner will be leading the race. PCTVS's runner runs at a speed of 10.1 meters per second. Clifton's runner runs at a rate of 10.9 meters per second and will start the last leg of the race 0.8 seconds behind the runner from PCTVS. Will PCTVS win the relay race?

Which excerpt from "The Catch” appeals to readers’ sense of hearing to help them imagine a scene?
His legs and thigh muscles ached as he trudged through the final swampland.
He tried to thrust off Rohan’s shoulders to push himself over in as though they were in a game of leap frog.
Just then, an old elf released a great eagle from its shackles, a signal for the race to start. When it squawked to freedom, the race began.
The gentle foothills ended quickly, and the runners made a steep scramble to the top of a cliff, followed by a daylong run up across uneven terrain of hard, coarse-grained rock.

Venus Waldo reviewed her account statement and wanted to verify that the interest amount was correct. Her new balance was $12,098.12 and her previous balance was $9,043.20. She had deposited $3,298.45 and withdrawn $300.00. Find the interest earned on Venus' savings account.
Answer:
The interest on the savings account is $46.47
Step-by-step explanation:
Here, we want to know the interest earned on the savings account.
The difference between the new and previous balance will be; 12,098.12 - 9,053.20 = $3,044.92
The difference between amount deposited and amount withdrawn is 3,298.45 - 300 = 2,998.45
This is the amount that is supposed to be on the account without interest
So the interest earned would be; 3044.92 - 2,998.45 = $46.47

Nisha is looking out the window of her apartment building at a sculpture in a park across the street. The top of Nisha's window is 60 feet from the ground. The angle of depression from the top of Nisha's window to the bottom of the sculpture is 25°. How far away from the building is the sculpture? Round your answer to the nearest hundredth.
A) 25.36 feet
B) 27.98 feet (NOT correct)
C) 100.22 feet
D) 128.67 feet (NOT correct)
Answer:
It is D 128.67
Solution:
Opposite=60
Angle=25degrees
Adjacent=?
Hypotenuse=?
We need to solve for the adjacent so don't worry about hypotenuse value.
Equation to solve for Adj.
tan(x)=Op./Hyp.
tan(25)=60/adj.
You then flip it
Adj.=60/tan(25)
Adj.=60/0.46630765815
Adj.=128.67 feet

(a) A square has a perimeter or 32 cm. What is the length of each side?
cm
(D) A square has an area of 144 m². What is the length of each side?
Answer:
A) 8cm
B) 12cm
Step-by-step explanation:
A) Perimeter = 4 × L
where L is the length of the sides
32 = 4 × L
32/4 = L
L = 8cm
B) Area = L^2
144 = L^2
L = square root of 144
L = 12cm
a)
The length of each side is 8 cm.
d)
The length of each side is 12 m.
What is a square?A square is a two-dimensional figure that has four sides and all four sides are equal.
The area of a square is given as side².
We have,
The perimeter of the square = 32 cm
Area of the square = 144 m²
Now,
Perimeter = 32 cm
4 Side = 32 cm
Side = 32 /4
Side = 8 cm
Area = 144 m²
Side² = 144
Side = 12 m
Thus,
The length of the side is 8 cm.
The length of the side is 12 m.

A math class is having a discussion on how to determine if the expressions 4 x minus x + 5 and 8 minus 3 x minus 3 are equivalent using substitution. The class has suggested four different methods. Which describes the correct method? Both expressions should be evaluated with one value. If the final values of the expressions are both positive, then the two expressions must be equivalent. Both expressions should be evaluated with one value. If the final values of the expressions are the same, then the two expressions must be equivalent. Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are positive, then the two expressions must be equivalent. Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.
Answer:
Both expressions should be evaluated with two different values. If for each substituted value, the final values of the expressions are the same, then the two expressions must be equivalent.Step-by-step explanation:
Given expressions
4x - x + 5 = 3x + 58 - 3x - 3 = -3x + 5Compared, we see the expressions are different as 3x and -3x have different coefficient

3(5 - x) = 7x - 2
Answer:
[tex]\boxed {x = \frac{17}{10}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]3(5 - x) = 7x - 2[/tex]
-Use Distributive Property:
[tex]3(5 - x) = 7x - 2[/tex]
[tex]15 - 3x = 7x - 2[/tex]
-Take [tex]7x[/tex] and subtract it from [tex]-3x[/tex]:
[tex]15 - 3x - 7x = 7x - 7x - 2[/tex]
[tex]15 - 10x = -2[/tex]
-Subtract [tex]15[/tex] to both sides:
[tex]15 - 15 - 10x = -2 - 15[/tex]
[tex]-10x = -17[/tex]
-Divide bot sides by [tex]-10[/tex]:
[tex]\frac{-10x}{-10} = \frac{-17}{-10}[/tex]
[tex]\boxed {x = \frac{17}{10}}[/tex]
So, the value of [tex]x[/tex] is [tex]\frac{17}{10}[/tex].

15. Definition 2: A line and a point not lying on the line.
Proof:
16. Definition 3: Two lines which intersect
Proof:
I need help with the proof :)
Answer:
14. Three points tat are not collinear
Three points that are not colinear consist of a line and a third point, therefore, joining all three points form a flat figure having a length and a width which is a two-dimensional flat figure or a plane
15. A line and a point not lying on the line
Like the example above, the joining of the points results in a two dimensional figure having a length and a width also known as a planar surface
16. Two lines which intersect at a point
Given two lines that intersect at a point, joining the other end point of the two lines results in the forming of a flat figure, that can be described in two dimensions also known as a planar surface or plane
Step-by-step explanation:
A plane in mathematics is a flat surface that has only two dimensions and extends infinitely in all directions

A particle travels in a circle around a fixed point at 16 revolutions per minute. The linear velocity of the particle is 240
inches per minute.
What is the distance, in inches, between the particle and the fixed point?
Answer:
15 inches
Step-by-step explanation:
We are given;
Linear velocity; V = 240 in/min
ω = 16 rev/min
Now, in circular motion, formula for linear velocity is;
V = ωr
Where ω is angular velocity and r is radius which is the distance between the object and the fixed point.
Thus;
240 = 16r
r = 240/16
r = 15 inches

Chanelle selects a marble from a container and then returns it to the container. When she does this 3 times, the probability of choosing a red marble all 3 times is 1/216. Based on this information, what is the probability of Chanelle choosing a red marble the first time she selects a marble?
Answer:
1 ÷ 6
Step-by-step explanation:
Let us assume the probability of the red marble for selecting it first time be x
And, it is to be done 3 times
that means
= 1 ÷ x × 1 ÷ x × 1 ÷ x
This equivalent to = 1 ÷ 216
And the 216 could be calculated by multiplied 6 3 times i.e.
= 6 × 6 × 6
= 216
So, the probability for selecting it for a first time is
= 1 ÷ 6
