A total of 300 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adults tickets sold. How many adult tickets were sold?

Answers

Answer 1
75 Adults
225 Students

You can get this information using this system of equations:

x + y = 300
x - 3y = 0
Answer 2

By setting up and solving an equation, it was determined that 75 adult tickets were sold for the school play.

To solve the problem of determining how many adult tickets were sold for the school play, we can set up an equation. Let's represent the number of adult tickets sold as A, and since the number of student tickets sold was three times that of adult tickets, we can express the student tickets sold as 3A. We know the total tickets sold were 300, so the equation to represent this scenario is:

A + 3A = 300

Combining like terms, we get:

4A = 300

Dividing both sides of the equation by 4 to solve for A gives us:

A = 300 / 4

A = 75

Therefore, 75 adult tickets were sold.

You want to determine the height of the screen at a drive-in movie theater. You use a cardboard square to line up the top and bottom of the screen structure. The vertical distance from the ground to your eye is 5.7 feet and the horizontal distance from you to the screen is 11 ft. The bottom of the screen is 6 feet from the ground. Approximate the height of the screen to the nearest tenth.



The height of the screen is about_______ feet

Answers

Final answer:

The height of the drive-in movie theater screen can be determined using proportions and similar triangles. The total height of the screen is found to be 11.7 feet.

Explanation:

To find the height of the screen, you'll need to use similar triangles, as the triangle formed by your line of sight to the top and bottom of the screen is similar to the triangle formed by the screen and the ground. The proportion of the vertical distance from your eye to the ground and the horizontal distance from you to the screen is equal to the proportion of the height of the screen and the horizontal distance from you to the screen. Hence, you can calculate the height of the screen using a cross-multiplication.

So, we have the equation: 5.7/11 = h/11, where h is the height of the screen from your eye level. Solving this gives us h=5.7 feet. Thus, the total height of the screen is the height from the ground to your eye level plus the height of the screen from your eye level. So, the total height = 5.7 feet + 6 feet = 11.7 feet.

Can derivatives be used to measure the the slope of the tangent line at x=a

Answers

Yes. In fact, that is basically the definition of a derivative. It is the instantaneous rate of change of a function. 

For example, picture the graph of the following function:

[tex]f(x) = x^2[/tex]

The slope is constantly changing at every x-value, so to find  the slope at x=a, we find the  derivative of the  function.

[tex]f'(x)=2x[/tex]

Once we have the derivative, simply plug in a for x to find the slope of the line tangent to f(x) at x=a.

For example, at x=5:

[tex]f'(5)=2(5)[/tex]

The slope of f(x) at x=5 is 10.

Write an equation in intercept form of the parabola that passes through the point (1,32) and has x-intercepts −7 and 3?

Answers

Given that the parabola passes through points (1,32) and the x-intercepts are (-7,0) and (3,0)
thus the equation will be as follows:
y=a(x-k)(x-h)
where:
(x-k) and (x-h) are the factors:
thus
y=a(x+7)(x-3)
y=a(x^2+4x-21)
But, when x=1, y=32
plugging this in the equation we get:
32=a(1^2+4(1)-21)
32=a(1+4-21)
32=-16a
hence:
a=-2
thus the eqiation will be:
y=-2(x^2+4x-21)
hence the equation is:
y=-2x^2-8x+42

The correct equation of the parabola in intercept form is [tex]2 (x+2)^2 -50[/tex].

To derive this equation, we will use the fact that the parabola passes through the given point (1,32) and has x-intercepts at -7 and 3.

[tex]y = k*(x+7)(x-3)[/tex]

[tex]y = k *(x^2 + 4x - 21)[/tex]

[tex]32 = k ( 8 * -2)32 = -16* kk = 32/-16 = -2[/tex]

[tex]y = -2(x+7)(x-3)[/tex]

[tex]= -2(x^2 + 4x - 21)[/tex]

[tex]= -2(x^2 +4x ) -42[/tex]

[tex]= 2(x^2 + 4x + 4) - 42 - 8[/tex]

The area of the whole shaded region is 12 * 10 = 120. 

There is the smaller non-shaded box though of 7 * 2 = 14. 

Take the difference of the two by doing 120 - 14 = 106 and that's your answer. 

106 m²
Step One
Find the area of the unshaded region
The unshaded region is a rectangle. Its area will be
A = L * W
L = 7 m
W =2 m 

Area = 7 * 2 = 14 m^2

Step Two
Find the Area of the entire region, both shaded and unshaded areas.
A = L * W
L = 10 m
W = 12 m

Area = 12 * 10 = 120 m^2

Step Three 
Find the area of the shaded region.
Shaded Area = whole area - unshaded region
Shaded Area =  120 m^2 - 14 m^2
Shaded Area = 106 m^2

Answer: 106 m^2

Determine whether quantities vary directly or inversely and find the constant of variation. It takes four identical water pumps 6 hours to fill a pool. How long would it take three of these same pumps to fill the pool, assuming they all pump at the same rate?

Answers

Let the number of water pumps be n and the time taken to fill the pool is t.

Now, we can see that higher the number of water pumps, lesser the time to fill the pool.

It means quantities  vary indirectly.

Thus, [tex]n=\frac{k}{t} , \text{ where k is the constant of variation}[/tex]

Now, we have been given that It takes four identical water pumps 6 hours to fill a pool.

Thus, we have

[tex]4=\frac{k}{6} \\ \\ k=24[/tex]

Hence, constant of variation is 24.

Now, we have to find the time that  three pumps will take to fill the same pool.

[tex]3=\frac{24}{t} \\ \\ 3y=24\\ \\ y=\frac{24}{3} \\ \\ y=8[/tex]

Hence, it will take 8 hours to fill the pool by three identical pumps.

B) period 3, amplitude 3
C) period 4, amplitude 1.5
D) period 4, amplitude 3

Answers

period 3, amplitude 1.5

Answer:

Option: A is the correct answer.

      A)  Period: 3 , amplitude : 1.5

Step-by-step explanation:

We know that Period of a function is the smallest value such that the function repeats after a fixed time.

and also the amplitude of the function is the height above or below the mid-line.

After looking at the graph we see that the period of the function is: 3

Since the function is repeating itself after every x=3.

Also, the mid-line of the function is: y= -0.5.

Hence, the height above the mid-line is: 1+0.5 = 1.5

        Hence, amplitude= 1.5

The larger square garden at Volterra Hall has sides twice as long as the smaller square garden. Together the gardens cover 18,000 square feet. Find the dimensions of each garden.

Answers

We will call:
[tex] G_{1}[/tex]: The larger square garden.
[tex] G_{2}[/tex]: The smaller square garden.

Given that both of then have square areas, then:
[tex] A_{G1} = L_{G1}^{2} [/tex]
[tex] A_{G2} = L_{G2}^{2} [/tex]

Being [tex] L_{G1} [/tex] the side of the larger garden and [tex] L_{G2} [/tex] the side of the smaller garden as shown in the figure.

The larger square garden at Volterra Hall has sides twice as long as the smaller square garden, thus:

[tex] L_{G1} = 2L_{G2}[/tex]

Together the gardens cover 18,000 square feet, so:
[tex]A_{G1} + A_{G2} = L_{G1}^{2} + L_{G2}^{2} = 18000[/tex]

Then:
[tex](2L_{G2})^{2} + L_{G2}^{2} = 18000[/tex]
[tex]4L_{G2}^{2} + L_{G2}^{2} = 18000[/tex]
[tex]5L_{G2}^{2} = 18000[/tex]
[tex]L_{G2}^{2} = 3600[/tex]
[tex]L_{G2} = \sqrt{3600}[/tex]
[tex]L_{G2} = 60[/tex]
[tex]L_{G1} = 2L_{G2} = 2(60) = 120[/tex]

Therefore:
Each side of the larger square garden is [tex] 120 ft [/tex] and each side of the smaller one is [tex] 60 ft[/tex] each. These are the dimensions.

The perimeter of the rectangle below is 90 units. find the length of side vy . write your answer without variables.

Answers

the picture in the attached figure

we know that
perimeter of a rectangle=2*[base+height]
base=3y+1
height=2y+3
perimeter=90 units
so
90=2*[(3y+1)+(2y+3)]-----> 90=2*[5y+4]----> 10y+8=90----> y=8.2 units

base=3y+1-----> base=3*8.2+1-----> 25.6 units
height=2y+3----> height= 2*8.2+3---> 19.4 units 

the answer is
the length of side vy is (2y+3)-----> 19.4 units

the length of side VY is equal to the height, which is 19.4 units. The formula for the perimeter of a rectangle is given as `2 * (base + height)`.

It's correctly stated that the base of the rectangle is `3y + 1`, and the height is `2y + 3`. The perimeter is given as `90 units`.

To find the dimensions, we set up an equation using the formula for the perimeter:

  90 = 2 * [(3y + 1) + (2y + 3)]

  This equation represents that the perimeter is equal to twice the sum of the base and height.

The equation is then simplified:

  90 = 2 * [5y + 4]

  By dividing both sides by 2, it becomes:

  5y + 4 = 45

  Solving for y:

  5y = 45 - 4

  5y = 41

  y = 41 / 5

  y = 8.2 units

  So, the value of y is correctly determined as 8.2 units.

With the value of y known, the base and height expressions are evaluated:

  Base: `3y + 1 = 3 * 8.2 + 1 = 24.6 + 1 = 25.6 units`

  Height: `2y + 3 = 2 * 8.2 + 3 = 16.4 + 3 = 19.4 units`

The dimensions of the rectangle are correctly calculated as follows:

  Base: 25.6 units

  Height: 19.4 units

  It's also mentioned that the length of side VY is equal to the height, which is 19.4 units.

The difference between the tallest person and the shortest is:

60 - 48 = 12 inches

Since the difference is small, we might use intervals smaller than 12 because if we used intervals of 12, we wouldn't know for sure the heights of the other students, and we would have to estimate their heights.

Using intervals of 8 would be the same, we would have to estimate the heights of most students.
