Students:960,Tables 24
a N=40t
b N=35t+90
c T=40n
d N=45t-90
Answer:
equation d
Step-by-step explanation:
The equation that best describes the relationship between the number of students and the number of tables is N = 40t. This equation can be obtained by observing the given data points and identifying the pattern. It can be verified by substituting the values of the number of students and tables.
Explanation:The equation that best describes the relationship between the number of students and the number of tables is N = 40t, where 'N' represents the number of students and 't' represents the number of tables. This equation is obtained by observing the given data points and identifying the pattern. For example, when the number of tables is 18, the number of students is 720, which can be represented as 720 = 40 * 18.
To verify this equation, let's check the other given data points. When the number of tables is 15, the number of students is 600, which can be represented as 600 = 40 * 15. Similarly, when the number of tables is 24, the number of students is 960, which can be represented as 960 = 40 * 24. Therefore, the equation N = 40t best represents the relationship between the number of students and the number of tables.

If a central angle measures 87°, then its arc will measure
half as much
twice as much
the same
Answer:
Half 43.5
The same 87
Twice as much 174
Step-by-step explanation:
The arc measure is approximately [tex]\(1.518 \pi\)[/tex] times the central angle. So, it's larger. The answer is B.
To find the measure of the arc corresponding to a central angle, you can use the formula:
[tex]\[ \text{Arc measure} = \frac{\text{Central angle}}{360^\circ} \times \text{circumference of the circle} \][/tex]
Since a full circle has a circumference of [tex]\( 2\pi \)[/tex] units, and the central angle is 87 degrees, you can substitute these values into the formula:
[tex]\[ \text{Arc measure} = \frac{87^\circ}{360^\circ} \times 2\pi \][/tex]
[tex]\[ \text{Arc measure} = \frac{87}{360} \times 2\pi \][/tex]
[tex]\[ \text{Arc measure} \approx 0.2417 \times 2\pi \][/tex]
[tex]\[ \text{Arc measure} \approx 1.518 \pi \][/tex]
Now, compare the result to the central angle. Since the arc measure is approximately [tex]\(1.518 \pi\)[/tex], and the central angle is 87 degrees, it's clear that the arc is larger than the central angle. So the correct answer is:
B. Twice as much
Complete Question:
If a central angle measures 87degree, then its arc will measure _____.
A. half as much
B. twice as much

Timothy’s mom bought 7/8 of a pound of grapes. She wants to split it between 8 kids. What fraction of the grapes will each kid get?
A. 1/8
B. 7/64
C. 9/64
Answer:
Option B
7/64
Step-by-step explanation:
Since the she bought 7/8 of a pound of grapes, the amount of grapes that Timothy's mum will be sharing is only 7/8 of a pound
Total number of kids = 6
To get the amount that each kid will get, we will have to divide 7/8 by 6
Hence we have
[tex]\frac{7}{8} \times \frac{1}{6}= \frac{7}{64}[/tex]
Hence, each child will get 7/64 of a pound of grapes, if the grapes are shared equally.
Answer:
B. 7/64
Step-by-step explanation:
Since Timothy's mom bought 7/8 of a pound of grapes, the amount of grapes that she will split between 8 kids will be:
7/8 ÷ 1/8 = 7/64
Therefore, each kid will get 7/64 of a pound of grapes, if the grapes are splitted equally.

To go to a movie, a family with 2 adults and 4 children spends $64. A family containing 1 adult and 3 children spends $42. Find the cost of an adult movie ticket and the cost of a child movie ticket.
Answer:
all work is pictured and shown
The cost of a ticket for an adult is $12 while for children it is $10.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
Let's assume that cost for adults is A while for children it is C
Now,
2 adults and 4 children spend $64.
2A + 4C = 64
1 adult and 3 children spend $42.
A + 3C = 42
Multiply by 2
2A + 6C = 84
By subtracting equations
6C - 4C = 84 - 64
2C = 20
C = 10
A = 42 - 3(10)
A = 12
Hence "The cost of a ticket for an adult is $12 while for children it is $10".

Answer:
y=4x
Step-by-step explanation:
First, find the slope
[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
We know 2 points, (2,8) and (12,48).
(2,8) can be (x1, y1)
(12,48) can be (x2, y2)
We can say that y2 is 48, y1 is 8, x2 is 12, and x1 is 2. Substitute them in
[tex]m=\frac{48-8}{12-2}[/tex]
[tex]m=\frac{40}{10}[/tex]
m=4
Now, we can use the point slope formula, since we have a point and the slope
[tex]y-y_{1} =m(x-x_{1})[/tex]
We know m, the slope is 4. We also know a point (2,8), which is (x1, y1). Substitute them in
y-8=4(x-2)
Distribute the 4
y-8=4*x-2*4
y-8=4x-8
Add 8 to both sides
y=4x
Answer:
y=4x
Step-by-step explanation:
You are given 3 points that are on this line. (0,0) which is the origin, (2,8) and (12,48)
Find the slope with (2,8) and (12,48)
Remember the slope formula:
(y2-y1) / (x2 - x1)
So:
(48 - 8) / (12 - 2)
40/10 = 4
And the y- intercept is 0 because the line goes through the origin.
So the equation is:
y=4x

Find length of PR. TR=x+11
Step-by-step explanation:
In a square,
we know that when diagonals bisect each other it is divided into two equal parts
so
TR = TP
So
PR = x +11 + x + 11
= 2x + 22
And
Both diagonals are equal so
QS = PR
7x - 3 = 2x + 22
7x - 2x = 22 + 3
5x = 25
x= 25 /5
x = 5
Now
PR = 2 * 5 +22= 10 +22 = 32
Answer:
PR = 34
Step-by-step explanation:
The diagonals of a square bisect each other, and are congruent, thus
QS = PR, that is
7x - 8 = x + 11 + x + 11 = 2x + 22 ( subtract 2x from both sides )
5x - 8 = 22 ( add 8 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Thus
PR = 2x + 22 = 2(6) + 22 = 12 + 22 = 34
Solve x2 + 14x = −24 by completing the square.

Find P (Sheep | Male)
Answer: I got 2/7
Step-by-step explanation:
The required probability of the sheep being male is 2/7 or 0.286 or 28%.
Given that,
Tabulated data has been given in the image for cow, sheep, horse chicken, and pigs for their male and female frequencies.
Probability for sheep in males to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events. Probability = Favorable Events / Total outcomes
Total number of male S(n) = 14
Number of male sheep E(n) = 4
Probability for sheep in males = E(n) / S(n)
= 4 /14
= 2 / 7
Thus, the required probability of the sheep being male is 2/7 or 0.286 or 28%.

You use substitution to solve a system of equations and, after simplifying the equations, end with an expression that says 0 = 4. What does that say about the the lines and about the number of solutions to the system?
Answer:
Step-by-step explanation:
It means there is no solution and the lines are parallel. It is called an inconsistent system.
I hope this helps
The system has no solution. Thus, the lines are parallel to each other.
The system of the equation has no solution. The expression leads to the value that is 0=4, which means you concluded the final result as 0=4.
Do you think practically it is possible, never, it is not possible to equate zero with four, same in the solutions of the system in the lines, this kind of results will not be taken by the intersecting lines.
Hence, the above expression is the condition for "No Solution"
If we try to evaluate the solution of the system that has no solution or an infinite number of solutions, then the variables are canceled out and only the constant values are left that are not equal.
Therefore, The lines are parallel and the system of the equation has no solution.

Jeffery is trying to decide between two investing account plans. An accountant
told Jeffery that Plan A offers a semi-annual compounded interest rate of 2.75%,
while Plan B offers 5.8% interest compounded annually. Which is the better
plan? Explain.
Plan B is the better investment option due to its higher effective annual interest rate compared to Plan A.
Explanation:The better plan is Plan B.
To compare, we can look at the effective annual interest rates for both plans. Plan A with semi-annual compounding has an effective annual interest rate of 2.75% x 2 = 5.5%. Plan B with annual compounding has a higher effective annual interest rate of 5.8%.
This indicates that Plan B would generate more returns over the same period compared to Plan A.
