Using the relation between velocity, distance and time, the items and graphs are matched as follows:
1. D.
2. B.
3. A.
4. C.
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
v = d/t.
Hence the distance is given by:
d = vt.
Along a city street, we have that:
The velocity would have a few peaks and few moments where it diminishes, due to breaking moments, hence item 4 matches with graph c.The distance would have a few slow increases and a few moments where it remains almost constant, hence item 1 matches with graph 4.We can verify this that when graph C(velocity) is zero, graph D(position) is constant.
Along a superhighway we have that:
The velocity would increase until the maximum velocity then remain constant there, hence item 3 matches with graph a.The distance would have an almost constant increase, hence item 2 matches with graph b.More can be learned about the relation between velocity, distance and time at https://brainly.com/question/24316569

The equation C= 8h+25 represents the cost in dollars, C, to rent a canoe, where h is the number of hours the canoe is rented.
What is the cost to rent a canoe for 4 hours?
Answers
The cost to rent a canoe for 4 hours is $57.
How to calculate the cost?It should be noted that the equation given is illustrated as equation C= 8h+25 represents the cost in dollars, C, to rent a canoe.
C = 8h + 25.
where h = number of hours
C = 8h + 25
When h = 4..
C = 8h + 25
C = 8(4) + 25
C = 32 + 25
C = 57
Therefore, the cost to rent a canoe for 4 hours is $57.

0.39 x 10^9
Put in scientific notation and explain how it works.
Answers
Answer:
3.9 x [tex]10^{8}[/tex]
Step-by-step explanation:
0.39 is not in scientific notation. For a number to be in scientific notation the first factor has to be 1 or greater, but less then 10. 0.39 is less than one.
First we must write 0.39 in scientific notation. We need to move the decimal so that the number is greater than 1, but less than ten. If we move the decimal one place to the right, we get 3.9. The standard number is smaller than 3.9. How much smaller? [tex]10^{-1}[/tex] smaller.
0.39 in scientific notation would be 3.9 x [tex]10^{-1}[/tex]. We cannot forget the [tex]10^{9}[/tex], so our number looks like this now:
3.9 x [tex]10^{-1}[/tex] x [tex]10^{9}[/tex] The product of powers principle tells us that if we have powers with the same bases, we can add the exponents.
3.9 x [tex]10^{-1+9}[/tex]
or 3.9 x [tex]10^{8}[/tex]
Given the following composite figure, d = 7.5 cm and w = 15.1 cm.
What is the area of the figure?
Answers
Answer:
157.41
Step-by-step explanation:
It can be identified that, given the figure, there is a rectangle and 2 semicircles.
Let's find the area of the rectangle first: A=L*w
Plugging in the given values => A=7.5*15.1 which equals 113.25.
Now the area for the semicircles: 1/2(3.14*r^2)
First, we need to find the radius. To find the radius, you just have to divide the diameter by 2. So, 7.5/2=3.75.
We can plug square the radius which is 3.75 and plug it into the formula: 1/2(3.14*3.75^2)=>22.078125.
22.078125 is the area of only one semicircle so we need to multiply it by 2 because we have two semicircles. So, we get 44.15625.
Finally, we can add them all up to find the total area of the figure: 113.25+44.15625=157.40625.

If the measure of angle 2=a+15 and the measure of angle 3=a+35, find a if HL is perpendicular to HJ
Answers
The value of a if HL is perpendicular to HJ is 20
How to determine the value
From the information given, we have that;
HL = angle 2 = a + 15HJ = angle 3 = HJIt is important to note that perpendicular lines always intersect each other and the angle between perpendicular lines is equivalent to 90 degrees.
Then, we have that;
Angle 2 + angle 3 = 90 degrees
Substitute the values
a + 15 + a + 35 = 90
collect like terms
2a + 50 = 90
2a = 90 - 50
subtract like terms
2a = 40
Make 'a' the subject
Divide both sides by 2
2a/2 = 40/2
a = 20
Thus, the value of a if HL is perpendicular to HJ is 20

last year 30 people went on a family trip to universal this is 5 times as many people that went the year before. how many people went the uear before?
Answers
Answer:
6 people
Step-by-step explanation:
To figure this out, let's set up an equation.
We know 30 people went last year to Universal, and that this is 5 times as many people as who went the year before
So to figure out how many went the year before, we divide 30 by 5
30/5 = 6
So 6 people went to Universal the year before.
I hope this helps :)
6 people went the year before
Explanation:
If 30 ppl went this year, you would have to find what times what equals 30. So jf it was 5 times more than before, the answer would be 6 because you would have to do 5 X 6 which would equal 30 so the answer is 6.

How far could you travel walking backwards in 15 minutes based on you speed for the 5 meter trial?
Answers
The correct answer answers will vary
Students should apply their findings to the calculation to determine a distance.
S=D÷T. The speed would be equal to the time and the speed from the 5-meter trial of walking backwards.
ought should be 15 minutes. To calculate the distance, students must multiply the speed by the time.
The distance that an item travels in relation to the amount of time it takes to do so may be used to define speed. In other terms, it is a measurement of an object's motion's speed without direction Velocities are what we get when speed and direction are combined.

Answers
You need 8 cups of juice for 12 cups of seltzer.
Representing the first statement in ratio form. So, number of cups of juice: number of cups of seltzer = 2:3. Similarly, for second statement, let the number of cups of juice be x.
Forming the equation with ratio on both sides -
2:3 = x:12
Writing the mentioned equation as fraction to solve for the value of x
x = (2 × 12)/3
Performing multiplication in numerator to find the value of x
x = 24/3
Dividing the numerator and denominator by 3 to find the value of x
x = 8

(a) Find the weight of a particular crate such that the probability of randomly selecting a heavier crate is 0.05.
(b) Find the probability that a randomly selected crate will weigh more than 16kg.
(c) If 20 crates are randomly and independently selected, what is the probability that
at least 2 of them will weigh more than 16kg?
Answers
a. The weight of a particular crate such that the probability of randomly selecting a heavier crate is 0.05 is 16.30kg.
b. The probability that a randomly selected crate will weigh more than 16kg is 0.0764.
c. The probability that.at least 2 of them will weigh more than 16kg is 0.4584.
How to calculate the probability?a. From the information, there is a mean of 14 kg and a standard deviation of 1.4 kg. The weight will be:
Let the weight = x
X = (Z × mean × standard deviation)
= (1.645 × 1.4 ×14)
= 16.30kg
b. The probability that a randomly selected crate will weigh more than 16kg will be:
P(z > 16)
= P(Z > 16-14/1.40)
= P(Z > 1.43)
Looking under the normal distribution table, the value is 0.0764.
c. The probability that at least 2 of them will weigh more than 16kg when 20 crates are randomly and independently selected will be through binomial distribution where n = 20 and p = 0.0764.
This will give a value of:
= 1 - 0.5416
= 0.4584
Therefore, the probability that.at least 2 of them will weigh more than 16kg is 0.4584.
