7. A train which is 100 meters long is traveling at a speed of 90 km per hour. How many
seconds will it take for this train to pass completely through a 300 meter tunnel?
A 4
B 8
C 12
D 16
E 20
The answer is D, 16. How do you get 16 tho?
Answers
Answer:
D; 16 seconds
Step-by-step explanation:
speed = distance/time
speed = 90 km/hr
We need to convert this to m/s because the tunnel is in meters and the time is in seconds:
[tex]\frac{90km}{hr} * \frac{1hr}{3600s} *\frac{1000m}{1km} =25m/s[/tex]
distance = 300 m (tunnel) + 100 m (train) = 400 meters
Solving for time:
[tex]25m/s=\frac{400m}{t} \\(25m/s)(t)=400m\\t=\frac{400m}{25m/s} \\t=16 s[/tex]

Jaden has 3 times as many pieces of gum as Brian has. Jaden has 150 pieces of gum. How many pieces of gum does Brian have?
Answers
Answer:
Brian has 50 pieces of gum
Step-by-step explanation:
Jaden has three times as many
Therefore-
n x 30 = 150
We need to solve for n
You can do that by dividing 150 by 3
150/3 = 50
So Brian has 50 pieces

Step-by-step explanation:
the angles of a triangle add up to 180°
17x+13x+6x=180
36x = 180
x = 5
Answer: 5
Step-by-step explanation:
To start off, the angles of a triangle add up to 180.
Therefore, you would find he answer by adding all the angles together and making it equal to 180.
13x+17x+6x=180
When you solve the equation, you will get X=5.
To check your work:
13 times 5=65
17 times 5=85
6 times 5=30
65+85+30=180

Find the x- and y-intercepts of the graph of the linear equation −6x+9y=−18.
Answers
Answer: it should be no solution.
Step-by-step explanation:
The graph of the linear equation −6x+9y=−18 , x = -3 and Y = -2.
What is linear equation?Linear equations are equations of the 1st degree. This is a straight line equation. The solutions of linear equations form the values that, when substituted into the unknown values, make the equation true. There is only one solution for one variable. For example, the equation x 2 = 0 has only one solution x = -2. However, for a linear equation in two variables, the solutions are calculated as the cross coordinates of a point in the Euclidean plane.
Given;
−6x+9y=−18
when x=0
then, -6(0)+9y= -18
9y = -18
y = -18/9
y = -2
put y= 0
-6x+9(0)= -18
-6x = -18
x = -18/6
x = -3

Hope it will help :)
Answer:
A. x = 3
Step-by-step explanation:
The question is;
[tex]x^{3} = 27[/tex]
To solve it, one has to do;
[tex]x = \sqrt[3]{27}[/tex]
(x equals the cube root of 27)
The cube root essentially asks, what number times itself three times equals the number under the radical.
3 times itself 3 times equals 27, hence the answer is 3.

Your given two side lengths of 6 centimeters and 9 centimeters. Which measurement can you use for the length of the third side to construct a valid triangle
Answers
Answer:
3cm < L < 15cm
Step-by-step explanation:
Given :
Side lengths:
Side 1 = 6cm and side 2 = 9cm
In other to construct a valid triangle, the length of the third side must lie in between.
That is ;
Minimum length must be greater than :
(side 2 - side 1)
9cm - 6cm = 3cm
Maximum length must not exceed :
(side 1 + side 2)
9cm + 6cm = 15cm
Hence, for a valid length for the 3rd side, L:
L > 3cm and L < 15 cm
3cm < L < 15cm

Write the equation in slope-intercept form of the line that passes through
(12,9) and is perpendicular to the graph of y = -3/4x + 1.
Answers
Answer:
We conclude that the equation in slope-intercept form of the line that passes through (12,9) and is perpendicular to the graph of y = -3/4x + 1 will be:
[tex]y=\frac{4}{3}x-7[/tex]Step-by-step explanation:
We know the slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the line
y = -3/4x + 1
comparing with the slope-intercept form of the line equation
The slope = m = -3/4
We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:
slope = m = -3/4
Thus, the slope of the new perpendicular line = – 1/(-3/4) = 4/3
Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values of the slope = 4/3 and the point (12, 9)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-9=\frac{4}{3}\left(x-12\right)[/tex]
Add 9 to both sides
[tex]y-9+9=\frac{4}{3}\left(x-12\right)+9[/tex]
[tex]y=\frac{4}{3}x-16+9[/tex]
[tex]y=\frac{4}{3}x-7[/tex]
Therefore, we conclude that the equation in slope-intercept form of the line that passes through (12,9) and is perpendicular to the graph of y = -3/4x + 1 will be:

The two-way frequency table below shows data on whether medicine was taken and cold length for
participants in a study conducted by The Cold Be Gone Company.
Complete the following two-way table of column relative frequencies.
(If necessary, round your answers to the nearest hundredth.)
PLEASE HELP
Answers
Answer: Cold length 7+days and medicine taken is 0.24, the box under is 0.76. Cold length 7+days and medicine not taken is 0.69 and the box under is 0.31. It should look like: 0.24 0.69
0.76. 0.31
Step-by-step explanation: the box is vertical, the total is on the bottom and not the side. This means that you would have to add 6 and 19 together to get 25. 6/25 is 0.24 and the box under would be the rest of the number to get to 1.00 (0.76) because the total is on the bottom. If the total was on the side then you would do 6+27=33, then 6/33 = 0.18 and the remaining amount needed to get to 1.00 is 0.82. Furthermore, if the table has the total at the bottom then, the numbers you add are on the bottom and top box. If the table has the total on the side then, the numbers you add are the boxes that are on the left and right. Remember to round to the nearest hundredth. Your welcome.
The two-way column relative frequency table is,
Medicine taken Medicine not taken
cold length (≥ 7 days) 0.24 0.69
cold length (< 7 days) 10.76 0.31
Total 1.00 1.00
What is two-way frequency table?"It is a way to display frequencies for two categorical variables." "One category is represented by rows and a second category is represented by columns."What is two-way relative frequency table?"It is a way to display relative frequencies (percentages or ratios), instead of just frequency counts."
For given example,
we have been given a two-way frequency table on whether medicine was taken and cold length.
We need to find the column relative frequency table.
First we find the total of each column.
Medicine taken Medicine not taken
cold length (≥ 7 days) 6 27
cold length (< 7 days) 19 12
Total 25 39
Now, divide each element of column by its respective total.
Medicine taken Medicine not taken
cold length (≥ 7 days) 6/25 27/39
cold length (< 7 days) 19/25 12/39
Total 25/25 39/39
Therefore, the two-way column relative frequency table would be,
Medicine taken Medicine not taken
cold length (≥ 7 days) 0.24 0.69
cold length (< 7 days) 10.76 0.31
Total 1.00 1.00
