Bill says that he can add 23 and 40 without regrouping, Do you think Bill is correct? Explain your answer
Answers
Given that the sum of the ones column is lower than 10 he does not need to regroup.
You have to regroup when the additions of the digits of the same place add up more than ten. For example adding 23 and 47.
In the columns of ones you have 3 + 7 = 10, then you write 0 in the ones column and carry the one to the next column (to the left). Now, regrouping, you will have 1 + 2 + 4 in the columns of the tens to obtain 7. And the result is 70.

Answer:
Amedia = 30 m
Top of the Lighthouse = +45 m
Boat = 0
Fish = - 10 m
The distance between Amelia and the fish is 40 meter
Step-by-step explanation:
Amelia = 30 m ( height of the cliff) since Amelia is standing on it's edge
-Top of lighthouse = lighthouse is located on top of the cliff ;
mean height of cliff + height of light house = (30 + 15) = 45 m
-The boat = 0 (on the surface of water) ; this is the sea level surface or point
-The fish = - 10 m (10 meters below the water surface).
Distance between Amelia and fish :
30 m - ( - 10 m) = 30 m + 10 m = 40 m

in a rectangle, all angles are 90 degrees and the diagonals are equal
meaning the diagonals bisect each other, they cut in equal halves
so. those two sides are equal, and thus they make up an isosceles triangle
on the sides
if those two sides are equal, the angles they make on the other side are equal
so if angle D is 55 degrees, angle A is 55 degrees
and the missing angle is 180 - (55 + 55) or 70
that's just the left-side
now, angle "x" on the right side, is a vertical angle of that angle on the left,
and vertical angles are equal, thus x = 70
