What is the speed (in miles per hour) of the train?
Answers
Answer:
50 miles per hour
Step-by-step explanation:
The speed can be found from a graph of distance versus time by looking at the slope of the graph. Here, the graph is a straight line, so the slope is constant. This means the speed is constant.
__
It can be convenient to determine the speed by looking at distance for times that are 1 time unit apart. Here, that could be the distances at t=0 and at t=1. We see in that hour, the train traveled from 100 miles to 150 miles away from the station. Its speed was 150 -100 = 50 miles per hour.

50 miles per hour

Javier and Ebony track the number of steps they walk. Javier records a walk of 6000 steps in 50 minutes. Ebony describes her step rate with the equation y=118, where y is the number of steps and x is the number of minutes she walks. This week, Javier and Ebony each walk a total of 5 hours. Who walks more steps?
Answers
Answer:
Javier walks more steps than ebony given the same minutes
Step-by-step explanation:
Javier records a walk of 6000 steps in 50 minutes.
Ebony describes her step rate with the equation y=118x
Where,
y = number of steps
x = number of minutes she walks
Javier and Ebony each walk a total of 5 hours. Who walks more steps?
5 hours = 5 × 60 minutes
= 300 minutes
Javier records a walk of 6000 steps in 50 minutes.
6000 : 50 minutes = x : 300 minutes
6000/50 = x / 300
Cross product
6000 * 300 = 50 * x
1,800,000 = 50x
x = 1,800,000 / 50
= 36,000
x = 36,000
Javier walks 36,000 steps
Ebony describes her step rate with the equation y = 118x
x = 300 minutes
y = 118(300)
= 35,400
y = 35,400
Ebony walks 35,400 steps
Therefore,
Javier walks more steps than ebony given the same minutes

In a survey of 3300 people who owned a certain type of car, 1320 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answers
Answer: The percent of the people surveyed were satisfied with the car = 40% .
Step-by-step explanation:
Given: Total number of people surveyed = 3300
Number of people said that they would buy that type of car again = 1320
i.e. Number of people were satisfied with the car = 1320
The percent of the people surveyed were satisfied with the car =
[tex]=\dfrac{1320}{3300}\times100\\\\=\dfrac{12}{30}\times100\\\\=\dfrac{4}{10}\times100\\\\=0.4\times100=40\%[/tex]
Hence, the percent of the people surveyed were satisfied with the car = 40% .

write the equation of the line in slope- intercept and point-slope form.
Answers
Answer:
Step-by-step explanation:
As we move from the x-intercept (-2, 0) to the y-intercept (0, 4), x increases by 2 (this is the run) and y by 4 (this is the rise). Thus, the slope of this line is
m = rise/run = 4/2 = 2.
Given the y-intercept (0, 4) and the slope (2), the slope-intercept form of the equation of this line is y = 2x + 4.
From this we get the point-slope form:
y = 2x + 4 becomes y - 4 = 2(x - 0), or just y - 4 = 2x.

15.13 cm
Step-by-step explanation:
We are given:
Lateral surface area of a right circular cone : πr√r² + h²
From the question, we know that:
Lateral surface area = 236.64cm²
Radius = 4.75cm
Height = ?
Making h the subject of the formula
h = √[(A/r)² - πr²]/π
h = √[(236.64/4.75)² - π ×4.75²]/π
h = √(2481.9275169 - 70.882184247)/π
h = 15.12975 cm
Approximately to the nearest hundredth = 15.13cm

The equation that represents the graph of the function g(x) is g(x) = f(x + 3) - 2
How to determine the function g(x)?The equation of the function f(x) is given as:
f(x) = x^3
The function g(x) is shifted down by 2 units and shifted left by 3 units, to get the function g(x)
This means that:
g(x) = f(x + 3) - 2
So, we have:
g(x) = f(x + 3) - 2
Hence, the equation that represents the graph of the function g(x) is g(x) = f(x + 3) - 2

What is the gradient of the straight line 2y = -3x - 8 ?
Answers
Answer:
- [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
Given
2y = - 3x - 8 ( divide all terms by 2 )
y = - [tex]\frac{3}{2}[/tex] x - 4 ← in slope- intercept form
with gradient = - [tex]\frac{3}{2}[/tex]
The gradient of the straight line 2y = -3x - 8 will be -1.5.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.
The slope(gradient) 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that the equation of the line is, 2y = -3x - 8
Rearrange the equation in the standard form of the equation as
2y = -3x - 8
y=-3/2 x-8/2
y= -1.5x - 4
Compare the obtained equation with the standard equation,y=mx+b. Where m is the gradient of the straight line.
m= -1.5
Thus, the gradient of the straight line 2y = -3x - 8 will be -1.5.

For a field trip, a highschool want to buy T-shirts and sweatshirts. The expression px + 29y repersents the cost of buying x T-shirts and y sweatshirts from the store. If each sweatshirt cost $17 more than a T-shirt what is the value of p ?
Answers
Answer:
The value of p is $12.
Step-by-step explanation:
Given;
c = px + 29y ,,,,,,,,,,,,,,,,,,, (1)
Where;
c = cost of buying x T-shirts and y sweatshirts from the store
p = price of one or each T-shirt = ?
x = number of T-shirts bought
29 = price of one or each sweatshirt
y = number of sweatshirt bought
Based on the above breakdown, if each sweatshirt cost $17 more than a T-shirt, the value of p can be calculated as follows:
29 = p + 17
p = 29 - 17
p = 12
Therefore, the value of p is $12.
Additional note:
Note that this is not part of the question but it is just an example to make you understand the question better.
If we assume that 10 T-shirts and 10 sweatshirts are bought from the store, we can use equation (1) above to calculate the cost as follows:
Where;
c = cost of buying x T-shirts and y sweatshirts from the store = ?
p = price of one or each T-shirt = 12
x = number of T-shirts bought = 10
29 = price of one or each sweatshirt
y = number of sweatshirt bought = 10
Substituting the values into equation (1), we have:
c = (12 * 10) + (29 * 10)
c = 120 + 290
c = 410
Therefore, the cost of of buying 10 T-shirts and 10 sweatshirts from the store will be $410.

The proportional relationship between the number of inches a candle has burned away, b, at any time in hours, t, can be represented by the equation b = 0.25tb=0.25t. What is the constant of proportionality from the time in hours to the inches of candle that has burned away?
Answers
Answer:
k = 0.25t^2
Step-by-step explanation:
Given the equation :
b = 0.25t
b = number of inches that has burned away
t = time
From our knowledge of variation;
Since candle length will decrease with time ;
b α 1/ t
b = k/t
Where k is the proportionality constant
Comparing the equation :
b = 0.25t
k/t = 0.25t
k = 0.25t^2
