Jamie downloaded 75.24 gigabytes of music onto her computer. The download took 3.8 hours. If the music downloaded at a constant rate, how many gigabytes of music were downloaded in one hour?
The gigabytes of music downloaded in one hour is 19.8 gb per hour
How many gigabytes of music were downloaded in one hour?From the question, we have the following parameters that can be used in our computation:
Size = 75.24 gigabytes
Time = 3.8 hours
The rate is then calculated as
Rate = Size/Time
Substitute the known values in the above equation, so, we have the following representation
Rate = 75.24/3.8
Evaluate
Rate = 19.8
Hence, the rate is 19.8 gb per hour

When the triangle has a base of 3 inches and an area of 5 square inches, its height is 3.33 inches.
what is triangle ?Since a polygon has number of sides and three vertices, it is a polygon. It is a fundamental geometric shape. Triangle ABC is the moniker given to a pyramid that has vertices A, B, and C. When the three factors are not collinear, a singular plane and triangle are found in Euclidean geometry. A triangle is a polygon if it has three sections and three corners. The points where the three sides meet are known as the triangle's corners. The product of three triangle angles is 180 degrees.

Step-by-step explanation:
the midpoint of a line segment from p1 to p2 is (-5,6) if p1=(-6,4) what is p2
The coordinates of the endpoint P2 in the line segment are (- 4, 8).
How to determine the coordinates of an endpoint by midpoint formula
In this problem we have the coordinates of an endpoint in a line segment and the midpoint of that segment, that is, the point in the line segment that partitions it into two parts of equal length. The formula needed to find the coordinates of the missing endpoint is:
0.5 · P1(x, y) + 0.5 · P2(x, y) = M(x, y)
Where:
P1(x, y), P2(x, y) - Coordinates of the endpoints of the line segment.M(x, y) - Coordinates of the midpoint.If we know that P1(x, y) = (- 6, 4) and M(x, y) = (- 5, 6), then the coordinates of the other endpoint are:
0.5 · P1(x, y) + 0.5 · P2(x, y) = M(x, y)
0.5 · (- 6, 4) + 0.5 · P2(x, y) = (- 5, 6)
(- 3, 2) + 0.5 · P2(x, y) = (- 5, 6)
2 · (- 3, 2) + P2(x, y) = 2 · (- 5, 6)
(- 6, 4) + P2(x, y) = (- 10, 12)
P2(x, y) = (- 10, 12) - (- 6, 4)

Draw A parallelogram with a 20 angle and a 160 angle
Answer:
see attached
Step-by-step explanation:
You want a parallelogram with angles of 20° and 160°.
AngleThe drawing will start with a line for one side. An angle of 20° can be drawn using a protractor, geometry app, or by approximating its slope.
The slope of a line 20° from the x-axis is tan(20°) ≈ 0.36397. A line with a slope of 4/11 = 0.3636... will have an angle of about 19.983° from the x-axis. For accuracy you can expect in a hand-drawn figure, this is "close enough." It is probably closer to 20° than you could draw using a protractor.
DrawingA parallelogram with the required angles is shown in the attachment. Point B is 11 units right and 4 units up from point A, so the angle at A is 20° when rounded to the nearest tenth.
__
Additional comment
Another very close approximation of tan(20°) is 9.9/27.2. A line with that slope makes an angle of 20.00002° with the x-axis.

f(x) and g(x) are inverses using composition
How to use composition to prove that f(x) and g(x) are inverses?A function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
To confirm the inverse relationship using composition.
For valid inverse f(g(x)) must be equal to g(f(x))
f(x) = ∛(x) + 13; g(x) = (x - 13)³:
f(g(x)) = f((x - 13)³)
f(g(x)) = ∛((x - 13)³) + 13
f(g(x)) = x - 13 + 13
f(g(x)) = x
g(f(x)) = g(∛(x) + 13)
g(f(x)) = (∛(x) + 13 - 13)³
g(f(x)) = (∛(x))³
g(f(x)) = x
Since f(g(x)) = g(f(x)) then f(x) and g(x) are inverse
f(x) = x³ + 1; g(x) = ∛(x - 1):
f(x) = x³ + 1; g(x) = ∛(x - 1)
f(g(x)) = f(∛(x - 1))
f(g(x)) = (∛(x - 1))³ + 1
f(g(x)) = x - 1 + 1
f(g(x)) = x
g(f(x)) = g(x³ + 1)
g(f(x)) = ∛((x³ + 1) - 1)
g(f(x)) = ∛(x³)
g(f(x)) = x
Since f(g(x)) = g(f(x)) then f(x) and g(x) are inverse

Using sum of angles in a triangle theorem and sine law, the angle x is 20 degrees, while the length of y and z are 25.83 and 26 respectively.
What is Law of SineSine law is a mathematical law that states that the ratio of the lengths of two sides of a triangle to the sines of the angles opposite to them is constant. It is also known as the sine rule or the law of sines.
This is represented mathematically as;
x /sin X = y / sin Y = z / sin Z
To find angle X, we can simply use the theorem of sum of angles in a triangle.
X + Y + Z = 180°
X + 79 + 81 = 180
X = 20°
Using sine law
x / sin X = y / sin Y
9 / sin 20 = y / sin 79
y = (9 * sin 79) / sin 20
y = 25.83
Using sine rule again
z / sin Z = x / sin X

C. -8 m/s
D. -10 m/s
The velocity of the ball when it returns to the ground is -8 m/s
What is an equation?An equation is an expression composed of variables and numbers linked together by mathematical operations.
The distance of a ball thrown upward is given by:
h(t) = -2t² + 12t - 10
The ball hits ground when h(t) = 0, hence:
-2t² + 12t - 10 = 0
t = 5 or 1
The velocity (V) of the ball is:
V = dh/dt
V = (d/dt)(-2t² + 12t - 10) = -4t + 12
V = -4t + 12
The ball hits ground when t = 5 or 1 s, hence:

advertised a rebate of $5 as well as a discount of 25% off all small appliances. Let r(x) = the price
after the rebate and let p(x) = the price after the discount.
Find r(p(x)) and p(r(x)). Which composition will save her the most money?
Let x = the original price of the electric wok.
r(x) = x - $5 (the price after the rebate)
p(x) = x * (1 - 0.25) (the price after the discount)
Given that x = $38, we can substitute that value in to find the final cost of the wok in each composition:
r(p(x)) = r(p(38)) = r(38 * (1 - 0.25)) = r(28.5) = 28.5 - $5 = $23.50
p(r(x)) = p(r(38)) = p(38 - $5) = p(33) = 33 * (1 - 0.25) = $24.75
So, r(p(x)) = $23.50 and p(r(x)) = $24.75
r(p(x)) will save her the most money.

What is the length of CD?
Answer:
CD = 15
Step-by-step explanation:
Pre-SolvingWe are given two quadrilaterals: CDEF and GIJH.
We know that CD = 3x - 6, and GI = x + 8.
We want to find the length of CD.
SolvingFinding xNotice how CD and GI both have one tick mark on them.
This indicates that these two are congruent, meaning that they have the same length.
Because of that, CD = GI.
If we substitute 3x - 6 for CD and x + 8 for GI, we get:
3x - 6 = x + 8
Now, we can solve this like a regular equation.
Add 6 to both sides.
3x - 6 = x + 8
+6 +6
_________________
3x = x + 14
Subtract x from both sides.
3x = x + 14
-x -x
_____________-
2x = 14
Divide both sides by 2.
2x = 14
÷2 ÷2

x = 7
Finding the length of CDWe found the value of x.
Now, substitute 7 as x in 3x-6 (the length of CD).
CD = 3x - 6 = 3(7) - 6 = 21 - 6 = 15
Therefore, CD = 15.

Answer:
Out of 50 students in a class, 40% are girls, meaning there are 50 x 40% = 20 girls in the class.
And the number of boys is 50 - 20 = 30 students.
If 30% of the girls wear spectacles, that means 30/100 x 20 = 6 girls wear spectacles.
And the number of girls not wearing spectacles is 20 - 6 = 14.
So the total number of girls wearing spectacles is 6, and the number of boys is 30, and the number of girls not wearing spectacles is 14.

See image below:
The point corresponding to the transformed function y=f(x/x)+1 is approximately (-4, 4.25), (-2, 2.5), (0, 1), (1, -0.5), (3, 1).
How to find the point corresponding to the transformed function y = f(x/x) + 1 ?we need to substitute x/x = 1 for the argument of the function f(x) and add 1 to the result.
Transformed point on point y on f(x) = f(x/x) + 1
(x, f(x)) (x, f(x/x) + 1)
(-4, 5) (-4, f(-2) + 1) ≒ (-4, 4.25)
(-2, 3) (-2, f(-1) + 1) ≈ (-2, 2.5)
(0, 0) (0, f(0) + 1)
= (0, 1)
(1, -2) (1, f(1) + 1) ≈ (1, -0.5)
(3, -4) (3, f(3/3) + 1) ≈ (3, 1)
Note that for the point (-4,5) you have to substitute x/x = -1/2 instead of x/x = 2. This gives x = -8. So the corresponding transformed point is (-4, f(-8) + 1) ≈ (-4, 2.75).
So the point corresponding to the transformed function y=f(x/x)+1 is approximately
(-4, 4.25), (-2, 2.5), (0, 1), (1, -0.5), (3, 1).
