Answer:
y = (7/4)x + 3
Step-by-step explanation:
(isolate the y variable by moving 7x) 4y = 7x + 12
(divide by 4 to get y by itself) y = (7/4)x + 3
I believe it is 5, the picture is kind of blurry but if 5 is a answer choice it is most likely 5
Answer:
506.7 cm²
Step-by-step explanation:
The amount of cardboard needed would be the surface area of the cone,
S= pi(r)(l+r) where r is the radius and l is the slant height.
You can find l using the Pythagorean theorem. l²=r²+h² which is l²=6²+20² and you get l = √436.
Plug r and l into the equation: S = 6pi(√436 + 6) = 506.7 cm²
