Vanessa exercised by walking around a pond. one day, she walked 338 mi. the distance around the pond is 38 mi. what equation can be used to find the number of times she walked around the pond? let n represent the number of times she walked around the pond.

Distance traveled by Vanessa around the pond = 338 miles.

Distance covered in one round = 38 miles

Let n be the number of rounds

n * 38 = 338 miles.

n =

equals to 8.9. Rounding it off to nearest whole number we get 9 rounds.

Hence the number of times she walked around the pond can be expressed in equation form as

n =

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
