You do 250 divided by 9 and get 27.7777777777 you round that to 27.8 which is your answer
Answer:
b
Step-by-step explanation:
There's only 1 orange and 1 yellow
Then there are 8 sections
therefore, 2/8 or 1/4
Answer:
y = 20 + 40x
Step-by-step explanation:
You can see that where x = 0, y = 20, which gives us the y intercept. We can also see that for each step on the grid, x increases by 0.5, and y increases by 20. Which means that y increases at a rate of 20/0.5 - or 40 - with respect to x.
Ok... to find the total surface area we have to realize a couple of things. First it's a triangular prism so we are dealing with 5 sides. Also the triangular sides are going to be congruent so all the side Lengths will also be congruent. The rectangular sides of the prism will have congruence as well. Lastly we have to know that to find the total surface area, you have to find the area of each side and add them together....
First the triangles. The area formula for a triangle is a = 1/2 base × height.
Since they are right triangles, the base and height are the legs of the right angle, so...
a = 1/2 (8 × 15)
a = 4 × 15 = 60 in^2
Don't forget we have 2 of them so surface area of both is 120 in^2.
Now the rectangles...
a = base × height
1) a= 13 × 8 = 104 in^2
2) a = 15 × 13 = 195 in^2
3) a = 13 × 17 = 221 in ^2
Now add them all up...
104 + 195 + 221 + 120 =
640 in^2 total surface area
