Answer:
Step-by-step explanation:
Rectangular prisms have F=6 faces and E=12 edges.
By cutting one corner, we are adding 3 edges.
By cutting two corners, we are adding 2*3 = 6 edges.
Therefore the new solid has 12 + 6 = 18 edges.
Answer:
52% and 7
Step-by-step explanation:
There are 25 squares of which 13 are shaded , then
× 100% = 13 × 4% = 52°
(b)
1 square represents 
× 100% = 1 × 4% = 4%
Then 80% = 80% ÷ 4% = 20
That is for 80% , 20 squares require to be shaded
That is 7 more than the 13 already shaded
Answer:
yes they are equivalent. if you simplify -21/-56 by dividing it by 3 you will get -7/-21 which equals to 7/21
The range of a function is the set of y-coordinates of all the points int he graph of the function.
Look at the graph. The vertex is point (2, -3).
The graph does not go lower than that point.
The lowest y-coordinate is -3.
The graph goes up forever on both sides until infinity.
The range is all numbers greater than or equal to -3.
Well do you know what a supplementary angles is ?
it is two angles that add up to 180 degrees
