Answer:
the sides of the triangle are 4 cm , 8 cm , 20 cm
Answer:
slope = -0.5
Step-by-step explanation:
The total surface area of the soup can would be
equivalent to the sum of the surface area of the 2 covers plus the surface area
of the side.
Surface area of the 2 covers = 2 π r^2
Surface area of the 2 covers = 2 π (2.5 cm)^2
Surface area of the 2 covers = 39.27 cm^2
Surface area of the side = 2 π r h
Surface area of the side = 2 π
(2.5 cm) (9 cm)
Surface area of the side = 141.37 cm^2
Total surface area = 39.27 cm^2 + 141.37
cm^2

Answer:
The y intercept is 4, or (0,4).
Step-by-step explanation:
You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.
In this type of problem, we would want to use a system of linear equations.
First, we need to find our equations. We know that the two boys traveled 275 km in total, and since x and y count the distance traveled (just in different modes of travel), we can write: x + y = 275.
Next, the problem says that they biked 55 km more than they bussed. So, x = y + 55.
Now that we have two equations to solve for two variables, we can lay them out next to each other:
x + y = 275
x = y + 55
We see that we can substitute x in the first equation with y + 55. This gives us
(y + 55) + y = 275
We solve for y and get y = 110 km by bus. But, we want to know how far they traveled by bike. So, since x = y + 55 and y = 110, we can solve for x by doing 110 + 55 = 165 km by bike.
The answer is 165 kilometers.
