What is system of equations?A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, also known as a system of equations or an equation system.
Assume s be the students tickets cost and g be the general admission cost.
From the given information,
⇒ s + g = 225 ..(1)
5s + 7g = 1500 ..(2)
From equation (1),
s = 225 - g
Plug the value of s in equation (2)
5(225 - g) + 7g = 1500
1125 - 5g + 7g = 1500
2g = 1500 - 1125
2g = 375
g = 187.5
Plug g = 125 in equation (1),
s + 187.5= 225
s = 225 - 187.5
s = 37.5

option B is the correct answer
What are the true statements about the point x and y?The points x and y and points C,D,E and f are shown in the figure, the true statement is determined as follows;
We know that, if two points lie in a plane, then the line drawn through the points will contained in the same plane.
The points C lies outside the plane Y and the point D lies on the plane Y, so the line drawn through the points C and D will not contained in plane Y.
So, option (A) is NOT correct.
The points D and E, both lie in the plane Y, so the line drawn through the points D and E will also contained in plane Y.
So, option (B) is CORRECT.
Since the plane X contain infinitely many points, so F is not the only point that can lie in plane X.
So, option (C) is NOT correct.
Similarly, there are infinitely many points in the plane Y, so the points D and E are not the only points that can lie in plane Y.
So, option (D) is NOT correct.

y = -2/3x -4/3
step-by-step explanation:
you start with 6x-9y = 12. you need to get y alone and on its own side of the equal sign.
starting easy, all coefficients (6, -9, and 12) have a GCF of 3. so, let's divide all sides by 3.
you are left with 2x-3y=4. now, we need to get -3y on its own side of the equal sign before we can get rid of its coefficient (-3). also, when identifying the coefficient of x, y, or any variable, include the + or - sign. you just don't need to write +, but you have to write -.
2x-3y=4 means we subtract 2x from both signs because it is positive. we now have
-3y = 2x + 4. let's divide by -3 to get y on it's own
y = -2/3x -4/3
What is the total payment required to pay off a promissory note issued for $500.00 at 8% ordinary interest and a 90-day term? A. $507.20 C. $508.00 B. $540.00 D. $510.00
Answers
The total payment required to pay off the promissory note debt of 90 days term is D. $510.00.
The promissory note issued is for $500.
The interest rate is 8%.
Furthermore, the time frame is 90 days.
So the total payment is
= $500 + ($500 × 8% × 90 days ÷ 360 days)
= $500 + ($500 × 8% × 1/4)
= $500 + 10
= $510

Fernanda is filling a cylindrical pot with cans of vegetable soup. The pot has a diameter of 15 in. and a height of 10 in. The soup can has a diameter of 4 in. and a height of 5 in. How many cans of soup will it take to fill up the pot?
Answers
Answer:
28.125 cans
Step-by-step explanation:
Step 1: Determine the Volume of the Pot
Diameter= 15 inches, therefore Radius=15/2=7.5 Inches
Height =10 Inch
Volume of a cylinder =\(\pi r^2h\)
Volume of the Pot \(=\pi*7.5^2*10=562.5\pi\) cubic inches.
Step 2: Determine the Volume of each can
Diameter= 4 inch, therefore Radius=4/2=2 Inches
Height =5 In.
Volume of a cylinder =\(\pi r^2h\)
Volume of one can \(=\pi*2^2*5=20\pi\) cubic inches.
Step 3: Divide the Volume of the Pot by the Volume of the can
To obtain the number of cans that will fill the pot, we divide the Volume of the Pot by the Volume of the can.
Volume of the Pot÷Volume of one can
\(=562.5\pi \div 20\pi\\=28.125 \:cans\)
Therefore, we conclude that it takes 28.125 cans to fill up the cylindrical pot of soup.

a) You will earn $
in interest (round to the nearest cent).
b) The future value is
(round to the nearest cent).
Answers
The simple interest is I = $ 303.33 and the amount after 2 months with rate of 13 % is A = $ 14,303.33
What is Simple Interest?Simple interest is a method of calculating interest that ignores the impact of compounding. While interest frequently compounds throughout the course of a loan's set periods, simple interest does not. Simple interest is calculated by multiplying the principal amount by the interest rate, times the number of periods.
Simple Interest = ( Principal Amount x Rate x Time Period ) / 100
Given data ,
Let the simple interest be represented as I
Let the amount with simple interest be A = P + I
Now , the principal P = $ 14,000
The rate of interest R = 13 %
The number of months = 2 months
The number of years = 2/12 years
Simple Interest I = ( Principal Amount x Rate x Time Period ) / 100
Substituting the values in the equation , we get
Simple Interest I = ( 14,000 x 13 x ( 2/12 ) ) / 100
On simplifying the equation , we get
Simple Interest I = $ 303.33
Now , the amount after 2 months = P + I
Amount = $ 14,000 + $ 303.33 = $ 14,303.33
Hence , the interest is $ 303.33

The 15 years it will take its population to reach 5,000 if initial population of 20 organisms.
What is an exponential function?
It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent \(\rm y = a^x\)
where a is a constant and a>1
Let's assume the exponential growth is:
\(\rm y = Ae^{rt}\)
From the problem:
\(\rm 130 = 20e^{5r}\)
\(\rm e^{5r}= 6.5\)
Taking ln both side:
We get:
r = 0.374
\(\rm 5000 = 20e^{0.374t}\)

Diego pays $4.50 for 3 pound of bananas and 2 pounds of oranges. One pound of oranges costs $0.75 more than one pound of bananas. Let b represent the price per pound of bananas . which equation represents the situation, and what is the price per pound of each fruit?
Answers
Answer:
D. 3b + 2(b + 0.75) = 4.50; $0.60 per pound of bananas, $1.35 per pound of oranges
Step-by-step explanation:
Price per pounds of bananas = b
Price per pound of oranges = b + $0.75
Diego buys:
3 pounds of bananas = 3(b) = 3b
2 pounds of oranges = 2(b + 0.75)
Amount paid by Diego is expressed as:
3b + 2(b + 0.75) = 4.50
To find the price per pound of each fruit, use the equation above to find the value of b:
3b + 2b + 1.50 = 4.50
Combine like terms
5b + 1.50 = 4.50
5b + 1.50 - 1.50 = 4.50 - 1.50
5b = 3
5b/5 = 3/5
b = 0.6
Price per pound of banana = b = $0.6
Price per pound of oranges = b + $0.75
Plug in the value of b
= $0.6 + $0.75
= $1.35

Answers
Answer:
a) ( 31.92 < μ < 33.88 )
The confidence interval is not very different from the confidence interval given in the question
b) ( 31.74 , 34.66 )
Step-by-step explanation:
n = 250
x ( mean ) = 32.9
std = 6.9
95% confidence interval
df = n - 1 = 250 - 1 = 249
a) construct confidence interval estimate
calculate for the margin of error
= \(t_{0.05/2} ,_{250-1} ( \frac{s}{\sqrt{n} } )\) ( using excel function: T.INV.2T(0.025,249) )
= 2.255 ( 6.9 / 15.81 )
= 0.98
Hence the confidence interval for the population
= ( x - 0.98 < μ < x + 0.98 )
= ( 31.92 < μ < 33.88 )
The confidence interval is not very different from the confidence interval given in the question
b) when n = 19
x = 33.2 and std = 2.6
margin of error = \(t_{0.05/2} ,_{19-1} ( \frac{s}{\sqrt{n} } )\) = 2.45 * ( 2.6 / 4.36 ) = 1.46
