Answer:
see below
Step-by-step explanation:
The trip takes 2 hours
Stopping every half hour means stopping at 30 minutes, 1 hour, 1.5 hours
We would not stop at 2 hours because we would be done.
One the number line R means rest stops
200 Km /4 means at 50 km, 100 km 150 km and 200 km
The rest stops are at 50 km 100 km 150 km (the one at 200 is at the end of the trip so it is not a rest stop
We have to stop for gas 3/4 of the way
200 *3/4 = 150 km
We will stop for gas at a rest stop at 150 km
Answers and Step-by-step explanations:
(a)
We want to find where to stop, so let's calculate the distances between the different rest points.
This is a distance-rate-time problem, so we need to use the equation d = rt, where d is the distance, r is the rate, and t is the time. Here, d = 200 km and t = 2 hours. So:
200 = r * 2
r = 100
Your speed is 100 km/hr. Now, you plan on stopping every half hour. We know that you drive 100 km in 1 hour, so that means you drive 100/2 = 50 km in half an hour. So, we want to draw a number line where every 50 km, there's a rest stop (red on attachment).
See attachment.
(b) We need to get gas at Fort MacLeod, which is 3/4 of the way to Lethbridge. The total distance is 200 km, so 3/4 of that will be:
(3/4) * 200 = 600 / 4 = 150 km
So, mark the place that is 150 km (blue on attachment).
See attachment.
Note that the green simply represents your entire trip from Calgary (start) to Lethbridge (end).

The number of laughs (denoted by L) can be defined as a function of the number of jokes (denoted by J), the amount of knowledge about the joke material (denoted by K), and the familiarity with the jokes (denoted by F) using this formula:
Answers
Answer:
L = f(J, K, F)
L = (JK²)/F
So, as the formula appears, the appropriate units will be option A.
Unit for number of laughs = (jokes*knowledge²) / familiarity
Just like the formula suggests.
Step-by-step explanation:
Complete Question
The number of laughs (denoted by L) can be defined as a function of the number of jokes (denoted by J), the amount of knowledge about the joke material (denoted by K) and the familiarity with the jokes (denoted by F) using this formula: L = (JK²)/F
Select an appropriate unit for number of laughs:
A) (jokes*knowledge²) / familiarity
B) familiarity / (jokes*knowledge²)
C) familiarity² / (jokes*knowledge)
D) (jokes*knowledge) / familiarity²
Solution
L = f(J, K, F)
where
L = number of laughs
J = number of jokes
K = amount of knowledge about the joke material
F = familiarity with the jokes
Analysing how the dependent variable depends on each of the independent variables.
- Number of jokes
The number of laughs will increase with the number of jokes and vice versa. It can be stated that there is a direct variation between the number of laughs and number of jokes.
- Amount of knowledge about the joke material
The more one understands the joke material, the funnier the joke. In fact, the joke can be termed funnier when one understands the joke material deeply. The direct variation of number of laughs to knowledge about joke material isn't just enough, the number of laughs varying directly as the square of the knowledge of joke material seems more fitting.
- Familiarity with the joke
The more familiar one is with a joke, the less funny it is. Hence, it's an inverse relationship between number of laughs and the familiarity with the joke.
L = (JK²)/F
So, as the formula appears, the appropriate units will be
(jokes*knowledge²) / familiarity
Just like the formula suggests.
Hope this Helps!!!
The question is incomplete. Here is the complete question.
The number of laughs (denoted by L) can be defined as a function of the number of jokes (denoted by J), the amount of knowledge about the joke material (denoted by K) and the familiarity with the jokes (denoted by F) using this formula: [tex]L = \frac{J.K^{2} }{F}[/tex].
Select an appropriate unit for number of laughs:
(jokes*knowledge²) / familiarity
familiarity / (jokes*knowledge²)
familiarity² / (jokes*knowledge)
(jokes*knowledge) / familiarity²
Answer: Unit for number of laughs is (jokes*knowledge²) / familiarity
Step-by-step explanation: Number of laughs (L) is related to jokes (J), knowledge (K) and familiarity (F) according to the proportion: [tex]L = \frac{J.K^{2} }{F}[/tex]
The unit for L will be: L = (jokes.knowledge²).familiarity⁻¹
or
L = [tex]\frac{jokes*knowledge^{2} }{familiarity}[/tex]

PLEASE HELP 10 POINTS WILL GIVE BRAINLIEST: Which geometric solid is the best model for the head of a human being?
A. Cylinder
B. Cone
C. Pyramid
D. Sphere
Answers
Answer:
sphere
Step-by-step explanation:
Human heads are close to circles and sometimes are circles
Sphere is the best model for the head of a human being.
A human head definitely doesn't represent a Cone neither a Pyramid.
Now a cylinder is a solid which is circular at its edges and straight in its length which clearly does not model the human head. Now the Sphere, it does closely represent the outside figure of a human head.
Thus Sphere is the best model for a human head.
Therefore option D, sphere is the correct answer.

What is the y-intercept of the line with equation y = 3x + 2
Answers
Answer:
The y-intercept is 2.
Step-by-step explanation:
We can find the y-intercept by looking at the linear equation y = mx + b.
m = slope
b = y-intercept
====================================================
Let's find the y-intercept of this line.
You should notice that the equation is written in Slope-Intercept Form:
[tex]\bigstar{\boxed{\pmb{y=mx+b}}}[/tex]
Where
m -> slope
b -> y-intercept
In the equation y=mx+b, the y-intercept is b, and in the equation y=3x+2, 2 is the y-intercept.

At the start of 2014 Mikes car was worth £12000. the value of his car decreased 30% every year.
work out the value of the car at the start of 2017
Answers
The worth of car at the start of 2014 = $12000
The value of the car decreased 30% every year.
At start of 2015:
30% of 12000 = \frac{30}{100} \times 12000
100
30
×12000 = 3600
So, the value of the car at start of 2015 = 12000-3600 = $8400.
At start of 2016:
30% of 8400 = \frac{30}{100} \times
8400
100
30
×8400 = 2520
So, the value of the car at start of 2016 = 8400-2520 = $5880.
At start of 2017:
30% of 5880 = \frac{30}{100} \times
5880
100
30
×5880 = 1764
the value of the car at start of 2017 = 5880-1764 = $4116.
So, the value of his car at the start of 2017 is $4116.

2. The cone has a radius of 30 mm and slant height of 34 mm. What is the height h for this cone?
Answers
Answer:
h = 16
Step-by-step explanation:
By applying the Pythagorean Theorem, the slant height is given by the formula:
[tex]\sqrt{r^2+h^2}[/tex]
34 = [tex]\sqrt{30^2 + h^2}[/tex]
[tex]34^2 = 30^2 + h^2[/tex]
[tex]1156 = 900 + h^2[/tex]

What is the value of x and the length of segment DE?
1. 5/9= 9/(2x+3)
2. 10x + 15 = 9(9)
x=?
length of de=?
Answers
Answer:
[tex]x = 6.6[/tex] and [tex]DE = 16.2[/tex]
Step-by-step explanation:
The question is incomplete as the attachment to solve segment DE is missing. However, see attached for complete question.
Given
[tex]\frac{5}{9}= \frac{9}{(2x+3)}[/tex]
Required
Find x
Length of DE
To find x, we need to first simplify the given equation
[tex]\frac{5}{9}= \frac{9}{(2x+3)}[/tex]
Multiply both sides by [tex]9(2x+3)[/tex]
[tex]\frac{5}{9} * 9(2x + 3) = \frac{9}{(2x+3)} * 9(2x + 3)[/tex]
[tex]5(2x + 3) = 9(9)[/tex]
[tex]10x + 15 = 81[/tex]
Subtract 15 from both sides
[tex]10x + 15 - 15 = 81 - 15[/tex]
[tex]10x = 66[/tex]
Divide both sides by 10
[tex]\frac{10x}{10} = \frac{66}{10}[/tex]
[tex]x = \frac{66}{10}[/tex]
[tex]x = 6.6[/tex]
From the attached;
[tex]DE = 2x + 3[/tex]
Substitute 6.6 for x
[tex]DE = 2(6.6) + 3[/tex]
[tex]DE = 13.2 + 3[/tex]
[tex]DE = 16.2[/tex]
Hence [tex]x = 6.6[/tex] and [tex]DE = 16.2[/tex]
Answer: 6.6 for the first x
Length of DE is 16.2
