1593 concert tickets were sold for a total of $22,491. If students paid $11 and nonstudents paid $17, how many student tickets were sold?

Answers

Answer 1
Answer:

765 student tickets were sold

Explanation:

Let the number of student tickets be represented by x

Let the number of nonstudent tickets be represented by y

1593 concert tickets were sold

x + y = 1593....................(1)

The total amount made = $22491

Cost of each student ticket = $11

Cost of each nonstudent ticket = $17

This can be interpreted mathematically as:

11x + 17y = 22491...............(2)

Mulitipy equation (1) by 17

17x + 17y = 27081...........(3)

Subtract equation (2) from equation (3)

6x = 4590

x = 4590/6

x = 765

765 student tickets were sold

Initial population = 875 people

Growth rate = 2%

The population after x years can be modeled below:

[tex]\begin{gathered} y=875(1+2\%)^x \\ =875(1+\frac{2}{100})^x \\ =875(1+0.02)^x \\ y=875(1.02)^x \end{gathered}[/tex]

We want to find the equation of the line in slope intercept form with the following values.

Slope = 1.3 and y-intercept ( 0, -6)

The equation of a line with slope m and y intercept (0,c) is;

If four friends collected 9 1/3 bags of treats and shared them among themselves equally,how many bags of treats did each person get?

Answers

It is given that four friends collected 9 1/3 bags of treats.

[tex]9\frac{1}{3}=\frac{28}{3}\text{ bags}[/tex]

Now 28/3 bags divided equally among 4 friends will be:

[tex]\frac{\frac{28}{3}}{4}=\frac{28}{12}=\frac{7}{3}=2\frac{1}{3}\text{ bags}[/tex]

Hence the total number of bags that each person will receive is 7/3 bags or 2 1/3 bags.

Find the range of allowable values based on the given information. round to the nearest tenth. 50; can vary by 30%

Answers

The allowable values are;

[tex]35\text{ to 65}[/tex]

To do this, we need to find the percentage value

That would be;

Now, the allowable values can be in both direction

Greater than 50 or less than 50

Diagram of the adjacent picture frame has outer dimensions = 24 cm x 28 cm and inner dimensions 16 cm x 20 cm. Find the area of each section of the frame, if the width of each section is same.

Answers

The area of the inner section is 320 cm^2

The area of the bigger section is 96 cm^2 (bigger trapezoid)

The area of the smaller trapezoid is 80 cm^2

Here, we want to calculate the area of each section of the frame

As we can see, there are 5 sections of the frame

The inner section represented by a rectangle and 4 adjoining shapes looking like a trapezoid

The inner part of the frame is a rectangle that measures 16 cm by 20 cm

Now, for the trapezoid part, we have 2 different sets

The first two set, has a longer length 28 cm, and shorter length of 20 cm

The second set has a longer length of 24 cm and a shorter length of 16 cm

Now, to get the area of the trapezoid, we need the height of the trapezoid which is called the width in this case. This measure corresponds to a measure of 4 cm on the two sets

Mathematically, the area of a trapezoid is;

[tex]A\text{ = }\frac{1}{2}(a\text{ + b)h}[/tex]

Where a is the longer length and b is the shorter length with h representing the width of 4 cm

For the bigger trapezoid, we have;

[tex]\frac{1}{2}(28+20)4=96cm^2[/tex]

For the smaller trapezoid, we have;

[tex]\frac{1}{2}\times(24_{}+16)\text{ 4 = }80cm^2[/tex]

Then, we have the inner section as;

[tex]\begin{gathered} \text{Area = length }\times\text{ width} \\ =\text{ 16 cm }\times20cm=320cm^2 \end{gathered}[/tex]

Which of the following is not a true postulate.Through any three noncollinear points there is exactly one planeThrough any two points there is exactly one plane.If two distinct lines intersect, then they intersect in exactly one point.If two distinct planes intersect, they intersect in exactly one line.

Answers

Answer:

Through any two points there is exactly one plane.

Step-by-Step explanation:

Postulate: Statement that is believed to be true, just without proof.

The first one is correct, that is, it is a true postulate.

The third statement is correct.

The fourth statement is also correct.

The answer is the second postulate.

It is stated that:

Through any two points there is exactly one plane.

But the correct postulate is:

Through any two points there is exactly one line.

So the answer is:

Through any two points there is exactly one plane.

7. Quinn had 3 more than two times the number of marbles Rowan has. Together they have 77marbles. How many marbles does each child have?

Answers

Explanation:

Let the number of marbles Rowan has = x

Two times x = 2x

3 more than two times the number of marbles Rowan has = 2x + 3

Quinn = 2x + 3

Together they have = 77 marbles

Rowan marbles + Quinn marbles = 77

x + (2x + 3) = 77

x + 2x + 3 = 77

Collect like terms:

3x = 77-3

3x = 74

Divide through by 3:

x = 74/3

x = 24.7

Write the equation of a perpendicular and parallel line to the following: (in picture)

Answers

anIf we have an equation of the form

[tex]y=mx+b[/tex]

then the equation of the perpendicular will be

[tex]y=-\frac{1}{m}x+c[/tex]

where c is any arbitrary constant determined by the point the line must pass through,

Now in our case, we have

[tex]y=-10x+20[/tex]

Therefore, the equation of the perpendicular line will be

[tex]y=\frac{1}{10}x+c[/tex]

We must choose c such that the above line passes through (-2,2).

Putting in y = 2 and x = 2 from (-2, 2) gives

[tex]2=\frac{1}{10}(-2)+c[/tex][tex]2=-\frac{1}{5}+c[/tex][tex]\therefore c=\frac{11}{5}.[/tex]

Hence, the equation of a line perpendicular y = -10x + 20 and passing through (-2, 2) is

[tex]y=\frac{1}{10}+\frac{11}{5}[/tex]

Now we find the equation of a line parallel to y = -10x+20 and passing through (-2,2).

Now, the slope of the parallel line is the same as that of the original equation; therefore the equation for the parallel line we have is

[tex]y=-10x+k[/tex]

We find k by using the point (-2,2) and substituting x = -2 and y = 2 into the above equation to get

[tex]2=-10(-2)+k[/tex][tex]2=20+k[/tex][tex]\therefore k=-18.[/tex]

Hence, the equation of the parallel line is

[tex]y=-10x-18[/tex]

1) Comparing those Mixed numbers we can stat which is greater, lesser than, or equal by dividing the numerator by the denominator and adding to the whole number:

[tex]\begin{gathered} 2\frac{5}{8}=\frac{8\cdot2+5}{8}=\frac{21}{8}=2.625 \\ 2\frac{1}{2}=\frac{2\cdot2+1}{2}=\frac{5}{2}=2.5 \\ 2\frac{5}{8}>\text{ 2}\frac{1}{2} \\ 2\frac{2}{8}=2\frac{1}{4}\text{ } \\ 1\frac{3}{8}<2\frac{3}{8} \\ 1\frac{5}{8}=\frac{8\cdot1+5}{8}=\frac{13}{8}=1.625 \\ 2\frac{3}{4}=2.75 \\ 1\frac{5}{8}<2\frac{3}{8} \\ \\ 1\frac{2}{4}=1\frac{1}{2}=1+0.5=1.5 \\ 1\frac{2}{8}=1\frac{1}{4}=1.25 \\ 1\frac{2}{4}>1\frac{2}{8} \\ \\ 2\frac{7}{8}>1\frac{7}{8} \end{gathered}[/tex]

So there are cases when the fraction is the same we just need to compare the whole number.

But in most cases, dividing the numerator by the denominator and writing it as a decimal number is really helpful

Of there are 2,000 pounds per ton, how many total tons of corn can be placed in the bin?

Answers

ANSWER :

a. 628 cubic foot

b. 52 cubic foot

c. 1.17 ton

EXPLANATION :

The volume formula of a cylinder is :

[tex]V=\pi r^2h[/tex]

The volume formula of a cone is :

[tex]V=\frac{1}{3}\pi r^2h[/tex]

From the problem, we have a diameter of 10 ft, so the radius is r = 5 ft

Cylinder's height is 8 ft and cone's height is 2 ft

a. volume of cylinder part :

[tex]\begin{gathered} V=\pi(5)^2(8) \\ V=628ft^3 \end{gathered}[/tex]

b. volume of cone part :

[tex]\begin{gathered} V=\frac{1}{3}\pi(5)^2(2) \\ V=52ft^3 \end{gathered}[/tex]

c. The combine volume is 628 + 52 = 680 cubic foot

A dry corn weighs 45 lbs per cubic foot.

That will be :

[tex]52ft^3\times\frac{45lbs}{ft^3}=2340lbs[/tex]

There are 2000 pounds per ton, so that will be :

[tex]2340lbs\times\frac{1ton}{2000lbs}=1.17ton[/tex]

Write an equation for the quadratic that passes through:  (0,9),(−6,9), (−5,4)

The general form of a quadratic is:

We need to plug in the 3 pair of points into "x" and "y" and simultaneously solve the 3 equations for a, b, and c.

Putting (0,9):

[tex]\begin{gathered} 9=a(0)^2+b(0)+c \\ c=9 \end{gathered}[/tex]

Putting (-6,9):

[tex]\begin{gathered} 9=a(-6)^2+b(-6)+c \\ 9=36a-6b+9 \\ 36a=6b \\ a=\frac{6b}{36} \\ a=\frac{b}{6} \end{gathered}[/tex]

Putting (-5,4):

[tex]\begin{gathered} 4=a(-5)^2+b(-5)+9 \\ 4=25a-5b+9 \\ 25a-5b=-5 \end{gathered}[/tex]

We substitute a=b/6 into this equation and solve for b:
