Jenna’s Drama Club is selling tickets at school. Parent tickets cost $6 and student tickets cost $3. Polly hopes to make a minimum of $500 in tickets, selling a maximum of 120 tickets. Write a system of inequalities to represent this context.
Answer:
6p + 3s = 500
p + s = 120
Step-by-step explanation:
p represents the parents and s represents the students
the total amount of tickets should be p and s, hence why they equal 120
The total cost should be 500, and each parent ticket is $6 while each student ticket is $3 hence the 6p and 3s

It's not possible to build a triangle with side lengths of 3, 3, and 9.
O A. True
OB. False
SUBM
Explanation:
The shorter side lengths 3 and 3 add to 3+3 = 6, which is not larger than the remaining side 9. This is why a triangle is not possible.
For a triangle to be possible, we need the sum of any two sides to be larger than the third side. Refer to the triangle inequality theorem.
I recommend making slips of paper that are 3 inches, 3 inches, and 9 inches long (or replace "inches" with "centimeters"). Then try to make a triangle with those slips of paper. You should find such a task is impossible: as mentioned, the 3 inch sides come up short when trying to attach to the 9 inch side.
The statement "It's not possible to build a triangle with side lengths of 3, 3, and 9" is true.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
A triangle cannot be formed with side lengths of 3, 3, and 9.
To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
However, in this case, the sum of the lengths of any two sides is 3+3=6, which is less than the length of the third side, 9.
Therefore, it is not possible to form a triangle with side lengths of 3, 3, and 9.
Thus,
The statement "It's not possible to build a triangle with side lengths of 3, 3, and 9" is true.

The model of a train is 5.5 in. The scale of that
model is 1: 40. What is the actual length of the
train ?
____feet.
The actual length of the train is calculated to be 18.33 feet
How to get the actual length of the trainScale factors are used to increase or decrease image. The situation of increment is usually called enlargement, and it is case for the problem.
solving for the factor, assuming the factor is k, using the ratio 1 : 40. the scale factor is 40 / 1 = 40
Solving for the actual length
actual length = scale facto * model length
actual length = k * 5.5 in
actual length = 40 * 5.5 in
actual length = 220 in
converting to feet
12 in = 1 foot
220 in = ?
cross multiplying
12 * ? = 220
? = 220 / 12
? = 18.33 feet
the actual length of the train is 18.33 feet

A population proportion is 0.30. A random sample of size 150 will be taken and the sample proportion will be used to estimate
the population proportion. Use the z-table.
Round your answers to four decimal places.
a. What is the probability that the sample proportion will be within ±0.03 of the population proportion?
b. What is the probability that the sample proportion will be within ±0.08 of the population proportion?
a. The probability that the sample proportion will be within ±0.03 of the population proportion is 0.6456.
b. The probability that the sample proportion will be within ±0.03 of the population proportion is 1.985.
What is population proportion?
The probability that a specific event will occur in the population is known as the population proportion. It is a parameter, and the sample proportion statistic is used to estimate it. The percentage of occurrences that occur in the sample is known as the sample proportion.
a. The probability that the sample proportion will be within ±0.03 of the population proportion is P(-0.03 < p - P < 0.003).
We Know that z-score of sample proportion is given by:
z = (p - P)/SE(p), where SE(p) represents standard error.
⇒SE(p) = √(0.3 * 0.7)/200
⇒SE(p) = √0.00105
⇒SE(p) = 0.0324
Now, using the z score, the probability P(-0.03 < p - P < 0.003) is computed as follows:
P(-0.03 < p - P < 0.003) = P(-0.03/SE(p) < p - P/SE(p) < 0.003/SE(p))
= P(-0.03/0.0324 < Z < 0.003/0.0324)
= P(−0.925926 < Z < 0.925926)
= 2P(0 < Z < 0.925926)
P(0 < Z < 0.925926) = 0.3228 (Using standard table)
So,
2P(0 < Z < 0.925926) = 2*0.3228 = 0.6456
Hence, the probability that the sample proportion will be within ±0.03 the population proportion is 0.6456.
b. The probability that the sample proportion will be within ±0.03 of the population proportion is P(-0.08 < p - P < 0.008).
Also, SE(p) = 0.0324
Now, using z score,
P(-0.08 < p - P < 0.008) = P(-0.08/SE(p) < p - P/SE(p) < 0.008/SE(p))
= P(-0.08/0.0324 < Z < 0.008/0.0324)
= P(−2.469135 < Z < 2.469135)
= 2P(0 < Z < 2.469135)
P(0 < Z < 2.469135) = 0.9925 (Using standard table)
So,
2P(0 < Z < 2.469135) = 2*0.9925 = 1.985
Hence, the probability that the sample proportion will be within ±0.03 of the population proportion is 1.985.

On Saturday, Carmen works no more than 8 hours at her job. Which inequality represents h, the number of hours Carmen works on Saturday?
The inequality h ≤ 8 represents the number of hours, Carmen works on the job.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
On Saturday, Carmen works no more than 8 hours at her job.
Let h be the number of hours, he works on the job.
According to the question,

The population of Laredo, Texas, was about
215,500 in 2007. It was about 123,000 in 1990. If we
assume that the population growth is constant and t
represents the number of years after 1990, write a
linear equation with an integer slope to estimate p,
Laredo's population for any year since 1990.
Answer:5441 is the population increase per year and 123,000 is when we start added the population increase. to get this equation i found the population increase between 2007 and 1990 which is 215,500-123,000 which is 92,500. to find the population increase per year you divide that by 17 which is the difference between 2007 and 1990 and you would get 5441.176. but since you can have part of a person i rounded it to 5441.
Step-by-step explanation:
Answer:
The linear equation representing the population growth since 1990 is p = 92t + 123000.
Where p is the population, 92 is the growth rate (215500-123000)/(2007-1990), and t is the years after 1990.

The equation to find the number of leaves which Aidan has now, n is given by 8 × 12 - 7 = n.
What is an equation?In Mathematics, an equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.
Next, we would write the equation that gives n, the number of leaves Aidan would have after collecting leaves for an art project as follows:
The number of leaves that Aidan collected from 8 different trees is equal to 8 leaves. Additionally, Aidan picks 12 leaves from each tree to have a total of 96;
n = 8 × 12 = 96.
Lastly, Aidan lost 7 leaves on his way home. Therefore, we would subtract 7 leaves from the total number of leaves that Aidan collected from 8 different trees;
n = 96 - 7 = 89 leaves.
In conclusion, the complete equation is represented by 8 × 12 - 7 = n.

What’s the answer to this
Answer:
see explanation
Step-by-step explanation:
to find the y- intercept, the point where the line crosses the y- axis.
Any point on the y- axis has an x- coordinate of zero.
let x = 0 in the equation and solve for y
- 4(0) + 7 = 2y - 3
0 + 7 = 2y - 3
7 = 2y - 3 ( add 3 to both sides )
10 = 2y ( divide both sides by 2 )
5 = y
then y- intercept = (0, 5 )
to find the x- intercept, the point where the line crosses the x- axis.
Any point on the x- axis has a y- coordinate of zero.
let y = 0 in the equation and solve for x
- 4x + 7 = 2(0) - 3
- 4x + 7 = 0 - 3
- 4x + 7 = - 3 ( subtract 7 from both sides )
- 4x = - 10 ( divide both sides by - 4 )
x = [tex]\frac{-10}{-4}[/tex] = [tex]\frac{10}{4}[/tex] = [tex]\frac{5}{2}[/tex]
then x- intercept = ( [tex]\frac{5}{2}[/tex], 0 ) or (2.5, 0 )
