Answer:
The answer is "2.2 h"
Step-by-step explanation:
Speed of Train B:
[tex]= \frac{3}{2} \times 70 \ mph \\\\= 105 \ mph[/tex]
Train B is then moving on:
[tex]= \frac{200 \ miles}{ 105 \ mph} \\\\= 1.905 \ h\\[/tex]
Then it takes Train A to the left:
[tex]\to 1.905\ h + 20 \ min \\\\= 1.905 \ h +0.333 \ h \\\\= 2.238 \ h[/tex]
To get train B to the reference point of train A = 2.2 h

Last year during the July 4th holiday, Americans ate about 150,000,000 hot dogs. Over the entire year, Americans ate a total of about 2 x 10^10. Compute how many times greater the total number of hot dogs eaten by Americans last year was than the number of hot dogs eaten during the 4th of July holiday. Round your answer to the nearest one.
Answer:
133 times
Step-by-step explanation:
First, convert 2 x 10^10 out of scientific notation:
20,000,000,000
Since this is the total amount of hotdogs, divide by the number eaten on July 4th:
20,000,000,000 / 150,000,000 = 133.3333333
Round to nearest one: 133 times
The total number of hot dogs eaten by Americans last year is 133 times greater than the number of hot dogs eaten during the 4th of July holiday.
What is division?A division is a process of splitting a specific amount into equal parts.
We have,
The number of hot dogs that ate on 4th July holiday= 150,000,000
The number of hot dogs that ate last year = 2 x [tex]10^{10}[/tex]
The number of times the total number of hot dogs eaten last year than the number of hot dogs eaten during the 4th of July holiday is:
Number of hot dogs eaten in July x M = Number of hot dogs eaten in the entire year
150,000,000 x M = 2 x [tex]10^{10}[/tex]
M = 2 x [tex]10^{10}[/tex] / 150,000,000
M = 20,000,000,000 / 150,000,000
M = 133.33
Rounding to the nearest one we get,
M = 133
Thus the total number of hot dogs eaten last year is 133 times greater than the number of hot dogs eaten during the 4th of July holiday.

what is the equation of the line that is parallel to the given line and passes through the point (2, 3)?
Given problems:
Line parallel that passes through (2,3);
Solution:
To solve this problem, we need to first understand what parallel lines are.
A parallel line is any two line that does not meet at any point.
In order to achieve this, both lines must have the same slope.
So, we find the slope of the given line and write in the form for a straight line.
Slope of line = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
let x₁, y₁ = (-2, -1)
x₂, y₂ = (2 , -3)
Now input the parameters and solve for the slope;
Slope of line = [tex]\frac{-3-(-1)}{2- (-1)}[/tex] = [tex]\frac{-2}{3}[/tex]
Any line that would be parallel to this must have the same slope.
Equation of a straight line;
y = mx + c;
y and x are the coordinates;
m is the slope
c is the y-axis intercept;
From (2, 3);
y = 3 and x = 2; m = [tex]\frac{-2}{3}[/tex]
3 = [tex]\frac{-2}{3}[/tex] x 2 + C
3 = [tex]-\frac{4}{3}[/tex] + C
C = [tex]\frac{13}{3}[/tex]
So the equation of the line is;
y = [tex]\frac{-2}{3} x[/tex] + [tex]\frac{13}{3}[/tex]
Multiply through by 3;
3y = -2x + 13
The equation of the line is 3y = -2x + 13
Answer:
x + 2y = 8

Answer:
No, because one x-value corresponds to two different y-values ⇒ D
Step-by-step explanation:
The relation of x and y can be a function if every x has only one value of y (x not repeated)
Examples:
The relation {(3, 5), (-4, 6), (0, 5)} is a function because every x has only one value of yThe relation {(3, 5), (-4, 6), (3, -5)} is not a function because x = 3 has two values of y 5 and -5Let us check the given table
∵ At x = 2, y = 1
∵ At x = 3, y = 4
∵ At x = 4, y = 4
∵ At x = 5, y = 2
∵ At x = 5, y = 5
∵ x = 5 has two values of y 2 and 5
→ That means x is repeated
∴ Not every x has only one value of y
∴ The table does not represent a function
∴ The right answer is D
