Answer:
-12
Step-by-step explanation:
So to start we need to know what makes a line parallel. In an equation we know that for lines to be parallel they must have the same slope(m).
Then, we need to know the slope-intercept form of an equation. The slope intercept form is
where
is the slope of the line and
is the y-intercept. In this problem where can see the second equation is already in this form.
Now that we know we need to find the slope, and we know that the second equation is in slope-intercept form we're going to convert the fist equation into the correct form.
To do this, we know we need to make sure
is the only thing on the left side of the equal sign. Currently, on the left side of the equal sign we have
so we have to divide both sides by
to get 
Now that we have it converted to slope-intercept form, we are going to look for what represents the slope or
in the equation. In this case the slope would be -12, so any line with a slope of -12 will be parallel.
The number 6.9 is already rounded to the nearest tenth.
4 feet is 48 inches.
So 4'2" would be 50 inches.
50/5=10
The class needs to make 10 tiles.
A= 50.27 cm^2 :) hopefully this is right
Answer:
11.781 cubic inches (round accordingly)
Step-by-step explanation:
The formula for the volume of a cone is:

where r is the radius and h is the height.
For our ice cream cone:
d = 3 inches
r = 1.5 inches (the radius is half of the diameter)
h= 5 inches
So all we have to do is plug in our values and solve for the volume:

So our final answer is around 11.8 cubic inches.
