Please help! It would mean a lot and thanks! :)
notsponge [240]

To add 1/2 and 5/12, make both fractions have the same denominator:

1/2 is the same as 6/12, so 6/12+5/12=11/12

Thus, B is right.

Pleasaaaaaaaaaaaaaaaassssssssssse help me anyone. I am sooooo stuck in this question.
SIZIF [17.4K]
First you take 7143-6997 to get her units used( it’s 146) since you know that the first 100 units cost 24p per unit so take 100 Times 24 p to get 2400p then take the remaining 46 units times 16 to get 384p.
Add 2400p+384p to get 2784p for her bill

A student walked 100 meters north, then 100 meters west. how many more meters did the student walk compared to their total displ
seraphim [82]

Using Pythagorean theorem, the student walked 53.58 meters more compared to the total displacement from the starting point.

If a student walks 100 meters north, then 100 meters west, then the path he travels resembles the sides of a right triangle (see attached photo).

Using Pythagorean theorem, we can solve for the total displacement from the starting point to the end point.

c^2 = a^2 + b^2

where c is the total displacement from the starting point to the end point

a is the distance he walks up north

b is the distance he walks to the west

c^2 = 100^2 + 100^2

c^2 = 10,000 + 10,000

c^2 = 20,000

c = 141.42 meters

Comparing the total distance the student walked and the total displacement from the starting point to the end point by subtraction.

100 meters + 100 meters - 141.42 meters = 53.58 meters
