Answer:
199.75km
Step-by-step explanation:
Step one:
given data
We are told that the time of travel is from
8:36- to 10:57
which is 2 hours 21 minutes
Hence the time taken is 2.35 hours
the speed is 85km/h
Step two:
From the expression
speed= distance/time
85= distance/2.35
distance= 85*2.35
distance= 199.75km
Answer: it traveled a distance of 199.75Km
Step-by-step explanation:
From the question , Let 0836 be 8:36
and 1057 be 10:57
Time of departure= 8:36
Time of arrival = 10:57
Time traveled = 10:57- 08:36= 2 Hours 21 minutes
changing trhe time to hours becomes 21/60 = 0.35 hours + 2 HOURS = 2.35 hours
Step 2
Speed = Distance / Time
Distance = Speed x Time
=85 km/hr x 2.35 hours
=199.75Km
sinA.secA
__________ = tan²A
cosecA.cosA
Answer:
Please check explanations for answer
Step-by-step explanation:
Here, we want to show that the left hand side equals the right hand side
We can express the left hand side as:
sin A/ cos A * sec A/cosec A
kindly recall that;
sin A/cos A = tan A
Also;
sec A = 1/ cos A
cosec A = 1/ sin A
Thus, we have that ;
tan A * 1/cos A / 1 / sin A
= tan A * sin A/cos A
This is;
tan A * tan A = tan^2 A

As table shows a proportional relationship between x and y then constant of proportionality are 20, 40, 0.2 and 20 respectively
In the first table, the constant of proportionality is 20 because each value of y is obtained by multiplying the corresponding value of x by 20.
In the second table, the constant of proportionality is 40 because each value of y is obtained by multiplying the corresponding value of x by 40.
In the third table, the constant of proportionality is 0.2 because each value of y is obtained by multiplying the corresponding value of x by 0.2.

The original price of a video game is $32.99 before tax. When Mario bought the video game it rang up as $26.39 before tax. He then paid 8% sales tax on the discounted price.
Part A: What is the percent discount on the game? Show all work and steps in your solution. (5 points)
Part B: What is the total amount that Mario paid for the video game including tax? Show all work and steps in your solution.
Answer:
Part A: The percent discount on game is 20%.
Part B: Mario paid a total of $28.50 including sales tax.
Step-by-step explanation:
Given that:
Part A:
Original price of video game = $32.99
Discounted price = $26.39
Amount of discount = 32.99 - 26.39 = $6.60
Discount percent = [tex]\frac{Amount\ of\ discount}{Original\ price}*100[/tex]
Discount percent = [tex]\frac{6.60}{32.99}*100 = 0.20*100[/tex]
Discount percent = 20%
Part B:
Sales tax = 8% of discounted price
Amount of sales tax = [tex]\frac{8}{100}*26.39 = 0.08*26.39[/tex]
Amount of sales tax = $2.11
Total amount = $26.39 + $ 2.11 = $28.50
Hence,
Part A: The percent discount on game is 20%.
Part B: Mario paid a total of $28.50 including sales tax.

Solve the system of linear equations by elimination.
3x−30=y
7y−6=3x
please explain
Answer: y = 6; x = 12
Step-by-step explanation:
3x - 30 = y
Change this into an equation where x and y are in the same side.
3x - 30 = y
Subtract y from both sides
3x - y - 30 = 0
Add 30 to both sides
3x - y = 30
7y - 6 = 3x
Do the same thing I did to the first equation
7y - 6 = 3x
Subtract 3x from both sides
-3x + 7y - 6 = 0
Add 6 to both sides
-3x + 7y = 6
We can now use the system of elimination to find x and y.
3x - y = 30
-3x + 7y = 6
After adding both equations, you get:
6y = 36
Divide 6 from both sides
y = 6
Since we now know y, we can solve for x.
3x - 30 = y
Substitute y for 6
3x - 30 = 6
Add 30 to both sides
3x = 36
Divide both sides by 3
x = 12
Hope this helped!
Answer:

What is HJ + JM?
The number line from minus four to four by increment of one and each tick mark is labeled. In this number line point minus four is also labeled as G, minus three is labeled as H, minus two is labeled as I, minus one is labeled as J, zero is labeled as K, one is labeled as L, two is labeled as M, three is labeled as N, and four is labeled as O.
Answer:
HJ + JM = 5
Step-by-step explanation:
The number line is majorly used to show the positions of directed numbers. For the given question, the number line has the required points as shown in the attachment to this answer.
From the number line,
HJ = -1 - (-3)
= -1 + 3
= 2
HJ = -2
JM = 2 - (-1)
= 2 + 1
= 3
Thus,
HJ + JM = 2 + 3
= 5
HJ + JM = 5
Find cos 0 for 0 = 30°
The 0 has a weird line through it
Answer: [tex]\frac{\sqrt{3}}{2}[/tex]
======================================================
Explanation:
The symbol [tex]\theta[/tex] is the greek letter theta. It's often used in trigonometry for angles.
In this case, [tex]\theta = 30^{\circ}[/tex]
So,
[tex]\cos(\theta) = \cos(30^{\circ}) = \frac{\sqrt{3}}{2}[/tex]
You'll need to use a reference sheet or the unit circle to determine the value of cos(30). Or you could use a 30-60-90 triangle template.
When using the unit circle, look in the upper right quadrant (which is quadrant 1). The angle 30 degrees is in this quadrant. Locate the terminal point and note how [tex]\frac{\sqrt{3}}{2}[/tex] is the x coordinate of the terminal point. This is due to [tex]x = \cos(\theta)[/tex]
Side note: [tex]\frac{\sqrt{3}}{2} \approx 0.866025[/tex]
If given f(x) = –4x – 2 and g(x) = 2x, what is (f · g)(x)?
A.
(f · g)(x) = –6x – 4
B.
(f · g)(x) = –8x2 – 4x
C.
(f · g)(x) = –6x – 2
D.
(f · g)(x) = –16x2 – 4x
Step-by-step explanation:
Given
f(x) = - 4x - 2
g(x) = 2x
(f • g) (x) = ?
We know
f(g(x)) = f ( 2x )
= - 4 ( 2x ) - 2
= - 8x - 2
What is the slope of the line y = 2x + 5?
Hello! (:
y=2x-5
This equation is written in slope-intercept form (y=mx+b)
Where
m is the slope of the line (2)
b is the y-intercept (5)
Hope it helps! Please ask if you have any query.
~An excited gal
[tex]MagicalNature[/tex]
The slope of the line y = 2x + 5 is 2 obtained by comparing it with slope intercept form y=mx+b, where m is slope.
The slope represents the rate at which the line is increasing or decreasing as you move along the x-axis.
The slope of a linear equation in the form y = mx + b is represented by "m."
In this case, "m" is 2, which means the slope of the line y = 2x + 5 is 2.
Since the slope is positive (2), it means that as x increases by 1 unit, y increases by 2 units, and as x decreases by 1 unit, y decreases by 2 units.
The slope of 2 indicates that the line is inclined, and it rises at a steady rate of 2 units for every 1 unit moved to the right along the x-axis.
Hence, slope of the line y = 2x + 5 is 2.
