Answer:

both people actually did the same work

Step-by-step explanation:

Work = Force × Distance

The person that climbed the steep spiral staircase used more force but covered a shorter distance. On the other hand, the person that walked up a gentle ramp used less force but covered a longer distance. Since both people reached the same height, the force against gravity was the same.

patriot [66]

Answer:

The required inequalities are s+g\leq 30 and s>7.

Step-by-step explanation:

Consider the provided information.

Daniel moves no more than 30 of his sheep and goats into another field.

Let s represent the number of sheep and g represent the number of goats.

No more than means the number of sheep and goats should be less than or equal to 30.

For less than or equal to use the inequality ≤

Hence the required inequality is: s+g\leq 30

More than 7 of his animals are sheep.

This can be represented as:

s>7

Hence, the required inequalities are s+g\leq 30 and s>7.

Draw the image of <EFG after the transformation. identify the type of transformation
pav-90 [236]
The transformation (x,y) --> (x,-y) is reflection over x axis. while the x coordinates in the image stay the same as the original, y coordinates change the sign. 
Therefore coordinates of original image and final image after reflection 
E - (0,3) --> E' (0,-3)
F - (2,2) --> F' (2,-2)
G - (1,1) --> G' (1,-1)
The diagram attached shows both the original image and image after reflection
