Answer:
Option C. 6 ft
Step-by-step explanation:
Let
h ----> the height of the ramp
we know that
The ramp is in the shape of a right triangle
so
Applying the Pythagoras theorem
where
c is the hypotenuse of the right triangle (the greatest side)
a and b are the legs of the right triangle
substitute the given values
square root both sides
Answer:
3. 314 student and 226 adult
4. x = 6.5, y = -0.5
Step-by-step explanation:
3. First we will take our information and make a system of equations:
is the number of adult tickets sold and
is the number of student tickets sold.
From the second equation we can rearange it to be:
Then we can plug in our new value of to our first equation
We can then find by plugging in s to our second equation
4. It is mostly solved already. We can take the value of y from the first equation and plug it into the second to get:
Then plug our value of x into the first equation to get:
Answer:
<em><u>4th one</u></em> is the right answer.
| x | -2 | 1 | 2 | 3 |
| y | -6 | 3| 6 | 9 |
Step-by-step explanation:
The x and y relationship is in the form y=kx and the graph starts from the origin.
Therefore the graph represents a proportional relationship which holds a equation y=x/3, where k=1/3.
