If the expression ax(4x − 2y − 3) simplifies to 24x^2− 12xy − 18, what must be the value of a?
Given:
Consider the expression [tex]ax(4x-2y-3)[/tex] simplifies to [tex]24x^2-12xy-18x[/tex].
To find:
The value of a.
Solution:
We have,
[tex]ax(4x-2y-3)=24x^2-12xy-18x[/tex]
Using distributive property, we get
[tex]4ax^2-2axy-3ax=24x^2-12xy-18x[/tex]
On comparing the coefficients of [tex]x^2[/tex] from both sides, we get
[tex]4a=24[/tex]
[tex]\Rightarrow a=6[/tex]
Therefore, the value of a is 6.

14V + 5 − 5V = 4(V + 15)
Answer:
V=11
Step-by-step explanation:
Simplify:
14V-5V+5=4V+60
9V+5=4V+60
Subtract 4V on both sides:
9V-4V+5=4V-4V+60
Solve:
5V+5=60
Subtract 5 on both sides:
5V+5-5=60-5
5V=55
Divide by 5
V=11
Hope this helps!
Step-by-step explanation:
14V+ 5 - 5V= 4V+ 60|-60|-4V
14V + 5 -5 V - 60 - 4V =0
<=> 5V - 55 =0 |+55

Calcular el área y el perímetro de un círculo que tiene 50 cm de radio
Answer:
Area: 7850 square cm
Perimeter: 314 cm.
Step-by-step explanation:
The area is [tex]\pi r^{2}[/tex]. With r=50, [tex]\pi 50^{2}[/tex]=2500π which is about (2500)(3.14)=7850.
The perimeter is [tex]2\pi r[/tex] which is the same as (diameter)(π). The diameter is 100, so [tex]100\pi[/tex] which is about (100)(3.14)=314.

Rita had $20. Then she saved $5.85 each week for 8 weeks, How much money does she have now? Use the bar diagram to solve the problem. Show your work*
Answer:
$66.80
Step-by-step explanation:
multiply 5.85 by 8 and then add the product to 20 to get the total
After the eight weeks, Rita has $66.8 now.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given, Rita had $20.
Then she saved $5.85 each week for 8 weeks
That means,
she saved the amount,
= amount saved in one week multiplied by 8
She saved the amount
= $5.85 x 8
$5.85 × 8 means $5.85 is added eight times.
Rita saved the amount
= $5.85 x 8
= $46.8
To find the total amount;
$20 + $46.8 = $66.8
And bar diagram is in the attached image.
Therefore, she has $66.8.

A pair of parallel lines is cut by a transversal, as shown:
A pair of parallel lines is shown cut by a transversal. Angle p is located in the upper right exterior next to the transversal, and angle q is located in the bottom left exterior corner of the transversal.
Which of the following best represents the relationship between angles p and q? (4 points)
p = 2q
p = 180 degrees − q
p = q
q = 180 degrees − p
Match the justifications for each step in order to prove the Alternate Interior Angles Theorem. Note that lines p and q are parallel. p∥q
∠1≅∠7
∠1≅∠3
∠3≅∠7
Answer:
Option (3)
Step-by-step explanation:
There are two parallel lines 'p' and 'q' and a transversal line is intersecting these lines at two distinct points.
Each pair of angles formed on the inner side of the parallel lines but opposite sides of the transversal line are the alternate interior angles.
Pair of angles (∠2 and ∠6) and (∠3 and ∠7) are the alternate interior angles.
Since, alternate interior angles are equal in measure,
∠2 ≅ ∠6
∠3 ≅ ∠7
Option (3) will be the answer.

> Question A normal distribution is observed from the number of points per game for a certain basketball player. If the mean is 15 points and the standard deviation is 3 points, what is the probability that in a randomly selected game, the player scored greater than 24 points?
Answer:
The probability that in a randomly selected game, the player scored greater than 24 points is 0.0013 or 0.13%
Step-by-step explanation:
Given that
Mean = μ = 15 points
SD = σ = 3 points
For calculating probability for a data point, first of all we have to calculate the z-score of the value.
We have to find the probability of score greater than 24, then the z-score of 24 is:
z-score = (x-μ)/σ
z = (24-15)/3
z = 9/3
z = 3
Now we have to use the z-score table to find the probability of z<3 then it will be subtracted from 1 to find the probability of z>3
So,
[tex]P(z<3) = 0.9987\\P(z>3) = 1 - P(z<3) = 1-0.9987 = 0.0013[/tex]
Converting into percentage
0.0013 * 100 = 0.13%
Hence,
The probability that in a randomly selected game, the player scored greater than 24 points is 0.0013 or 0.13%
Answer:0.15%
Step-by-step explanation:
Notice that 24 points is three standard deviations greater than the mean. Based on the Empirical Rule, 99.7% of the player's game scores are within three standard deviations of the mean. Since the normal distribution is symmetric, this implies that 0.15% of the player's game scores are greater than three standard deviation more than the mean.
