Sam wants to know how long it will take to fill his baby pool that holds 24 gallons. After 1 minute, there are 2 gallons of water in the pool. He plots the points (0,0) and (1,2) on his coordinate plane. What is the x-value of the point (x, 24)? A) 6 B) 12 C) 23 D) 25
The unit rate is gallons per minute, which in this case is 2 gallons per minute. Therefore it will take 12 minutes to fill up a 24 gallon pool.

Use Euler’s Formula to find the number of edges in a polyhedron with seven faces: two pentagons and five rectangles.
To determine the number of edges in a polyhedron with seven faces, two being pentagons and five being rectangles, you apply Euler's formula, resulting in a total of 15 edges.
To find the number of edges in a polyhedron with seven faces using Euler's formula, which is V - E + F = 2, we first need to determine the number of vertices (V) and faces (F) of the polyhedron.
Given that the polyhedron has two pentagons and five rectangles, we can calculate the total number of vertices. Each pentagon has 5 vertices and each rectangle has 4, but since rectangles share sides, some vertices will be counted twice.
Therefore, for the rectangles, we should calculate the vertices as if there were four distinct ones and then subtract the overlaps. Assuming all rectangles share exactly one side with its adjacent, we would have 4 vertices for each rectangle minus 2 for each shared side, resulting in 2 vertices per rectangle.
With five rectangles, that's 10 vertices, plus the 10 from the two pentagons, we get 20 vertices in total. Now, we apply Euler's formula: V - E + F = 2, substituting the values:
E = V - F + 2
E = 20 - 7 + 2
E = 15
Therefore, the polyhedron has 15 edges. .

The probability that the Cubs win their first game is 1/3. The probability that the Cubs win their second game is 3/7. What is the probability that the Cubs win games?
The correct answer is:
1/7.
Explanation:
The two events, the Cubs winning their first game and the Cubs winning their second game, are independent. This is because the Cubs winning their first game does not affect the probability of the Cubs winning their second game.
Since the events are independent, to find the probability that both events occur, multiply the probabilities:
1/3(3/7) = (1*3)/(3*7) = 3/21 = 1/7

An organization will give a prize to a local artist. The artist will be randomly chosen from among 10 painters, 3 sculptors, and 5 photographers. What is the probability that the artist chosen will be a sculptor or a photographer?
The probability is 8/18 or 44%.
Since there are 3 sculptors and 5 photographers, and the question is asking for either a sculptor or photographer, you add them together. There are a total of 18 artists, and the probability is the chance of a certain thing happening over the total amount of things that can happen (i.e. a coin landing on heads is 50%).
The answer would be 8/18.

If the exchange rate changes from $1.45 = 1 euro to $1.37 = 1 euro, then
Factor this trinomial.
x2 – 8x + 15
A. (x – 1)(x – 15)
B. (x – 3)(x + 5)
C. (x – 3)(x – 5)
D. (x – 1)(x + 15)
To factor x^2 -8x + 15, we find two numbers that multiply to get 15 and add to get -8. These two numbers can be -5 and -3. Therefore, this factors as
x^2 - 8x + 15 = (x-5)(x-3)

In which quadrant of the coordinate plane is (-2a - 3, -3b - 5), if a = -3 and b = 3?
After substituting a = -3 and b = 3 into the point (-2a - 3, -3b - 5), we get the point (3, -14), which lies in the fourth quadrant of the coordinate plane.
To determine in which quadrant of the coordinate plane the point (-2a - 3, -3b - 5) is located, we substitute the values a = -3 and b = 3 into the coordinates. First, for the x-coordinate we have:
-2(-3) - 3 = 6 - 3 = 3
And for the y-coordinate:
-3(3) - 5 = -9 - 5 = -14
The resulting point is (3, -14), which is located in the fourth quadrant because the x-value is positive and the y-value is negative.
Jesse made a model of a mountain range for class. to do this, he bought a cylinder of cardboard and cut it into three cones. each cone is 5 inches tall and has a diameter of 4 inches. what was the volume of the original cylinder jesse bought in terms of \piπ?
The volume of the original cylinder that Jesse bought is 20π cubic inches.
To find the volume of the original cylinder Jesse bought, we need to use the volume formula for a cylinder:
V = πr²h
First, we need to find the volume of each cone using the formula:
Volume of a cone = (1/3)πr²h
Given:
Height(h) of each cone = 5 inchesDiameter of each cone = 4 inches, so the radius(r) = 4/2 = 2 inchesVolume of one cone:
V_cone = (1/3)π(2)²(5) = (1/3)π(4)(5) = (20/3)π cubic inches
Total volume of three cones:
V_total_cones = 3 × (20/3)π = 20π cubic inches
Since the volume of the cylinder equals the total volume of the cones:
V_cylinder = 20π cubic inches

A number line contains points Q, R, S, and T. Point Q is on the coordinate 24, R is on the coordinate 28, S is on the coordinate 29, T is on the coordinate 42. Find the probability that a point chosen at random on QT is on ST. Express your answer as a percent.
A. 25%
B. 42.2%
C. 50%
D. 72.2%
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
A number line contains points Q, R, S, and T
Point Q is on the coordinate 24
Point R is on the coordinate 28
Point S is on the coordinate 29
Point T is on the coordinate 42
So, According to given condition,
QT is on the coordinate is given by
[tex]42-24=18[/tex]
ST is on the coordinate is given by
[tex]42-29=13[/tex]
So, probability that a point chosen at random on QT is on ST is given by
[tex]\frac{13}{18}\times 100\\\\=72.22\%[/tex]
Hence, option 'D' is correct.
