Answer:
The system of equations is given as:
x ≥ $500
y ≥ $800
x + y ≤ 1600
20x + 30y ≥ 2800
Step-by-step explanation:
From the question
We are told that
x = Number of $20 seats
y = Number of $30 seats
$20 seats = At least $500 (greater than or equal to)
$30 seats = At least $800 (greater than or equal to)
You are designing a social hall that would seat no more than 1600 people
No more than means less than or equal to ≤ 1600 people
x + y ≤ 1600 people
Total revenue generated = At least $2800. This means ≥ (greater than or equal to).
20x + 30y ≥ $2800
The system of equations is given as:
x ≥ $500
y ≥ $800
x + y ≤ 1600
20x + 30y ≥ 2800
Option C is the correct Option.

Triangles ABC and DEF are shown below. Angle A measures 51°, angle Fmeasures
39°, and x = 6.
7.5
10
Is ABC is similar to DEF?
Answer:
Yes
Step-by-step explanation:
yes
They both have interior angles of 90-51-39, which automatically makes them similar. You could also see the dilation factor of .75 based on the 2 sides of a right angle to prove it.
ΔABC and ΔDEF are similar by AA Similarity Theorem.
Given in the question,
In ΔABC,
m∠A = 51°AB = 8 unitsBC = 10 unitsIn ΔDEF,
m∠F = 39°EF = 7.5 unitsTo prove these right triangles similar, we can use AA-Similarity Theorem,
By applying triangle sum theorem in ΔDEF,
m∠D + m∠E + m∠F = 180°
m∠D + 90° + 39° = 180°
m∠D = 51°
Hence, ∠D ≅ ∠A and ∠E ≅ ∠B
Therefore, ΔABC ~ ΔDEF [By AA Similarity Theorem]

Samuel and Jill had 576 stamps in all. Samuel gave 1/7 of his stamps
to Jill. Then, Jill gave 1/4 of the total number of stamps she now had to
Samuel. In the end, both of them had the same number of stamps.
What was the difference in the number of stamps they each had at first?
Answer:
128
Step-by-step explanation:
Sam has X stamps.
Jill has (576-X) Stamps.
X-x/7 = 6x/7 = Sam's bal.
576-x + x/7 = 576 - 6x/7 = Jill's bal.
1/4(576-6x/7) = 144 - 6x/28
3/4(576-6x/7) = 432 - 9x/14 = Jill's new
bal.
6x/7 + 144-6x/28 = 144 + 24x/28-6x/28 =
144 + 9x/14 = Sam's new bal.
Jill's new bal = Sam's new bal
432 - 9x/14 = 144 + 9x/14
18x/14 = 144-432 = 288
18x = 4032
X = 224
576-X = 576-224 = 352.
Difference = 352 - 224= 128

What is an equation of the line that passes through the points (-6,-5) and (-4,-6)? Put your answer in fully redued form.
Answer:
y=-5/2x-16
Step-by-step explanation:
1. Find the slope using the slope formula and the two coordinates provided.
m=y2-y1/x2-x1
Put the y values from both coordinates on top and the x values on bottom.
-6--5/-4--6
Solve for M. -6--5/-4--6 = -6+1/-4+6
= -5/2
Slope is -5/2.
2. Using the slope and one of the coordinates (doesn't matter which), put the equation in point-slope form: y-y1=m(x-x1)
y+6=-5/2(x+4)
3. Distribute the -5/2 to x+4 and simplify (multiply x and 4 by -5/2)
y+6=-5/2x-10
Subtract 6 from both sides to get y by itself.
y=-5/2x-16
4. y=-5/2x-16 is your answer
7) Let the random variable X represent the amount of money Dan makes doing lawn care in a randomly selected week in the summerAssume that is Normal with mean $ 240 and standard deviation $60. the probability that in a randomly selected week, Dan will make less than $255 is :
A. 0.6
B. 0.7
C. 0.8
D.0.9
E. 1
Answer:
Option A. 0.6 is the right answer.
Step-by-step explanation:
Given information is:
Mean = $240
SD = $60
The probability of Dan making less than $255 has to be found.
Let x = 255
First of all, we will find the z-score of the given value
[tex]z = \frac{x-mean}{SD}\\z = \frac{255-240}{60}\\z = \frac{15}{60}\\z = 0.25[/tex]
Now the z-score table will be used to see the probability of less than 0.25
Using the z-score table, we get:
P(x<0.25) = 0.5987
As the answer choices are rounded off to one decimal place, we will round off our answer to one digit after the decimal point
0.5987 => 0.6
Hence,
Option A. 0.6 is the right answer.

1a. A plant is $24 with a discount of 25% off. What is the discount ? (The
amount you save)
Answer:
The discount is $6, and the original price with the discount is $18.
Step-by-step explanation:
First we need to convert the percent 25%. into a decimal, 0.25.
Now we need to multiply the cost and the percentage. 24 × 0.25 = 6.
The discount is $6.
Now we need to subtract the original price and the discount.
$24 - $6 = $18.

A straight line passes through A (-2, 0) and B (2,-k). The line is
perpendicular to a line 34+2x=5 Determine the value of K.
Answer:
-6Step-by-step explanation:
Let the slope of the first line be m1
Let the slope of the second line be m2
If both lines are perpendicular, then;
m1m2 = -1
Get m1, the slope of the line passing through A (-2, 0) and B (2,-k).
m1 = y2-y1/x2-x1
m1 = -k-0/2-(-2)
m1 = -k/4
Get the slope of the line 3y + 2x = 5
Rewrite the equation;
3y = -2x + 5
y = -2/3 x + 5/3
Hence the slope of the line m2 is -2/3
Since m1m2 = -1, then;
-k/4(-2/3) = -1
2k/12 = -1
k/6 = -1
k = -6
Hence the value of k is -6

What is the correct formula for the following Arithmetic Sequence?
-4, -1, 2, 5, 8,…
Group of answer choices
an = 4 – 3(n – 1)
an = 4 + 3(n – 1)
an = -4 – 3(n – 1)
an = -4 + 3(n – 1)
Answer:
Concept: Arithmetic Sequence & Series
Notice the change is +3 for the first iteration and then +3 for the second iteration and so on You must represent it a series.Hence it must work for any nth variable So we have -4+3(n-1) Rate positively and give brainlistThe solution is, the correct formula for the following Arithmetic Sequence: -4, -1, 2, 5, 8,…, is, an = -4 + 3(n – 1), the value of the n-th term.
We know that,
from Arithmetic Sequence & Series we get,
The nth term of AP : a_n = a + (n – 1) × d
where, a = first term
d = common difference,
Notice the change is +3 for the first iteration and then +3 for the second iteration and so on
i.e. here,
a = -4
d = +3
Hence it must work for any nth variable.
So we have -4+3(n-1)
Hence, we get, an = -4 + 3(n – 1).

Assume that X is Normal with mean $ 240 and standard deviation $60 . the probability that , in a randomly selected week , Dan will make less than $ 255
Answer:
The probability of Dan making less than $255 is 0.5987 or 59.87%
Step-by-step explanation:
Given that:
Mean = μ = $240
SD = σ = $60
We have to find the probability that Dan will make less than $255
First of all, we have to find the z-score of 255
z-score is denoted by z and is given by the formula
[tex]z = \frac{x-mean}{SD}[/tex]
Here,
x = 255
Putting the values
[tex]z = \frac{255-240}{60}\\z = \frac{15}{60}\\z = 0.25[/tex]
Now we have to look at the z-score table to find the probability of 0.25
P(x<255) = 0.5987
Converting into percentage
59.87%
Hence,
The probability of Dan making less than $255 is 0.5987 or 59.87%
The population of a town is 2100 and increasing at a rate of 1.3% per year, while the number of cats in the town is currently 1000 and increasing at a rate of 8% per year. Assuming this trend continues, estimate when the cat population will exceed the human population in this town.
Answer:
when # cats exceeds 2,313
Step-by-step explanation:
if you graph y = .013x + 2100 and y = .08 + 1000 you will see the lines intersect when the town population is 16,418 and the number of cats equals 2,313.

For the value of a you determined above what is the value for b so that the equation has infinitely many solutions
Support your answer. Explain your reasoning
Part 2
Find one value for a and one value for b so that the equation has no solution.
Find the value of a you determined above what is the value for b so that the equation has no solution.
Support your answer explain your reasoning.
Answer:
Let's solve for a.
2(3x+4)=ax+b
Step 1: Flip the equation.
ax+b=6x+8
Step 2: Add -b to both sides.
ax+b+−b=6x+8+−b
ax=−b+6x+8
Step 3: Divide both sides by x.
