Canada Olympic Park features sports training and entertainment facilities.The monster Zip line produces average speed of 120 kilometers per hour. A smaller line produces speeds represented by the function d=50h where d is the distance in kilometers after h hours. How much farther could you travel on the Monster Zip line in 0.25 hours
The answers I can choose are
18km
16km
20km
17.5km
Answer:
17.5 Km
Step-by-step explanation:
In Monstor zip line, it's 120 km /hour
so in 0.25 hours, it's 0.25 * 120 = 30 Km
in another small
d = 50*h
= 50*0.25
= 12.5 km
so you travel (30-12.5)km farther on the monster zip line = 17.5 Km

Answer:
The measures of angles A, B, and C are respectively 21°, 125°, and 34°
Step-by-step explanation:
Equations
We are given some conditions applying to the internal angles on a triangle ABC.
The measure of angle A is 13 less than the measure of angle C.
The measure of angle B is 11 less than 4 times the measure of angle C
Let x = measure of angle C
The first conditions states:
[tex]m\angle A = x-13[/tex]
The second conditions states:
[tex]m\angle B = 4x-11[/tex]
The sum of all angles must be 180°, thus:
[tex]x - 13 + 4x - 11 + x = 180[/tex]
Simplifying:
6x -24 = 180
Adding 24:
6x = 204
Dividing by 6:
x = 204/6
x = 34
[tex]m\angle C = x = 34^\circ[/tex]
[tex]m\angle B = 4x-11 = 4*34-11 = 125^\circ[/tex]
[tex]m\angle A = x - 13 = 34 - 13 = 21^\circ[/tex]
The measures of angles A, B, and C are respectively 21°, 125°, and 34°

Answer:
A''(3/2, -3)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and rotation.
If a point A(x, y) is reflected over the x axis, the new point would be A'(x, -y).
If a point A(x, y) is dilated by a factor k, the new point would be A'(kx, ky).
Given that Trapezoid QUAD has vertices at Q(-4, 0), U(-2, 4), A(2, 4) and D(4, 0). If the trapezoid is reflected over the x-axis to create trapezoid Q'U'A'D', the vertices would be at Q'(-4, 0), U'(-2, -4), A'(2, -4) and D'(4, 0).
If trapezoid Q'U'A'D'is dilated by a factor of 3/4 respect to the origin to create trapezoid Q"U"A"D", the vertices would be at Q''(-3, 0), U''(-3/2, -3), A''(3/2, -3) and D''(3, 0)

The domain and range of the function f(x)=28 is Domain: All real numbers Range: {-28}. The correct option is D.
What are the domain and range of a function?The domain is the set of values for which the given function is defined.The range is the set of all values which the given function can output.The given function f(x)=-28 has a domain of all real numbers because the function can take any value of x. But, the range of the function is only -28. This is because for any input(x) the value of the function will remain the same which is equal to -28.

Joey and Doug hung out at the mall on Saturday. They spent 1-hour shopping for clothes and 1 hour and 30 minutes at the food court. Then they spent 30 minutes at the video arcade before heading home. It was 2:45 P.M. when Joey and Doug left the mall. What time did they start shopping for clothes?
Answer:
They started shopping for cloths at 11:45 AM
Step-by-step explanation:
First of all we have to calculate the whole time that they spent in the mall starting from shopping.
They spent 1 hour on shopping, 1 hour and 30 minutes at food court and 30 minutes in video arcade which makes:
[tex]1 + 1.5+ 0.5 = 3\ hours[/tex]
as 30 minutes is equal to half hour so we used 0.5 in place of it.
Now we know that they left at 02:45 PM. We have to see what time it was 3 hours ago.
[tex]02:45\ PM - 03:00 = 11:45\ AM[/tex]

21% of the students at a High are in Maths group, 15 % are in science group, and 6 % are in both. If a student is selected randomly , what is the probability that the student is in maths or science group?
Answer:
6%
Step-by-step explanation:
The probability of picking a maths student = 21% = 21/100
The probability of picking a science student = 15% = 15/100 = 3/20
The probability of picking in both = 6/100 = 3/50
The probability that the student is in maths or science = 21/100 - 15/100 = 6/100 = 6%.

A scale factor of 4 applied to the dimensions of the prism. What effect will this have on the volume?
Answer:
its not A just took the test
Step-by-step explanation:
The effect this scale factor has on the volume is that the volume will be 64 times larger. The correct option is B.
What is a Scale factor?Scaled figures are zoomed in or zoomed out (or just no zoom) versions of each other. They have scaled versions of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.
So, if a side of a figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called a scale factor.
The linear things grow linearly like length, height etc.
The quantities which are squares or multiple linear things twice grow by the square of the scale factor. Thus, we need to multiply or divide by k².
to get each other corresponding quantities from their similar figures' quantities.
So the area of the first figure = k² × area of the second figure
Similarly, increasing product-derived quantities will need increased power of 'k' to get the corresponding quantity. Thus, for volume, it is k cubed. or
The volume of the first figure = k³ × volume of the second figure.
It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.
Since the volume is the product of three linear quantities.
Therefore, if the scale factor of 4 is applied to the given prism then the volume of the prism will grow by 4³. Thus, we can write,
The volume of the scaled prism = 4³ ×Volume of the original volume
The volume of the scaled prism = 64 ×Volume of the original volume
Hence, the effect this scale factor has on the volume is that the volume will be 64 times larger.

If -3/2 and 5 are solutions, what is the value of a, b, and c? (ax+b)(x+c)=0
Answer:
Step-by-step explanation:
If -3/2 and 5 are solutions to the quadratic equation, hence the expression will give;
(x-(-3/2))(x-5) = 0
(x+3/2)(x-5) = 0
Compare the resulting expression with (ax+b)(x+c)=0, we can see that;
ax = x
divide both sides by x
ax/x = x/x
a = 1
b = 3/2
-5 = +c
c = -5
Hence a = 1, = 3/2 and c = -5

A watermelon was ejected from a catapult reaching a maximum height of 20 ft. The watermelon left the catapult when it was 4 ft off the ground and hit the ground 45 ft away from the catapult. Can the equation that models the path of the watermelon be written given the information in the problem? If so, find the equation. If not, state what other information is needed.
Answer:
Step-by-step explanation:
No, the equation cannot be written with the given information. The distance from the catapult when the watermelon reached the maximum height is needed. Since the watermelon did not start on the ground, it cannot be assumed that the maximum was reached half the distance to the landing point.

2.5y + 3x = 27
5x – 2.5y = 5
What equation is the result of adding the two equations?
What is the solution to the system?
Answer:
8x = 32
x = 4
y = 6
Step-by-step explanation:
2.5y + 3x = 27
5x – 2.5y = 5
_____________
8x = 32 (equation obtained after adding the two equations)
x = 32/8
x = 4
Plug x = 4 in 2.5y + 3x = 27
2.5y + 3*4 = 27
2.5y + 12 = 27
2.5y = 27 - 12
2.y5= 15
y = 15/2.5
y = 6
The equation results of adding the two equations is 8x = 32.
The solution to the system is (4, 6).
What are linear and non-linear functions?A straight line on the coordinate plane is represented by a linear function. As an illustration, the equation y = 3x – 2 depicts a linear function because it is a straight line in the coordinate plane.
Any function whose graph is not a straight line is said to be nonlinear. Any curve other than a straight line can be a graph of it.
An example of a non-linear function is a quadratic function.
Given, A system of linear equations in variables 'x' and 'y'.
2.5y + 3x = 27...(i) and 5x - 2.5y = 5...(ii)'
Reaaranging eqn(i) we have
3x + 2.5y = 27...(iii)
Adding (ii) and (ii) we have,
8x = 32. (As + 2.5y and - 2.5y cancels)
x = 32/8.
x = 4.
Putting the value of 'x' in eqn(i) we have,
2.5y + 12 = 27.
2.5y = 15.
y = 6.
So, The solution to the system is (4, 6).
