20.2 * -2.5ft = -50.5ft
Hence, Winston reach -50.5 feet during his deepest dive.
C) 225m
Explanation:
Looking at the board we see each side is 25m in length. Each side has 5 squares, therefore the length of one side of each square is 5m (25m/5=5).
Let’s count how many full squares there are. There’s 5 completely full squares (one in the middle, and one on each of the four edges).
There’s also half-full squares which we COULD calculate separately using the area of a triangle. However, we know that two halves make one full square so let’s count how many full blocks these make up. There’s 8 triangles (or half full squares), therefore there are 4 full squares.
Adding this to the clearly full blocks shows 4+5=9. There are 9 fully shaded squares. The area of a square is A=s x s (Area = length of side x length of side). Therefore, one square’s area is 5x5=25m^2. The area of 9 squares is 25 x 9 = 225m^2.
Therefore the answer is C
Answer:
-8, 16, -32, 64
Step-by-step explanation:
a1 = -8
r = -2
a2 = -8(-2)=16
a3 = -8(-2)²=-8(4)=-32
a4=-8(-2)³=-8(-8)=64
Answer:
set c.2,4,6,8,10,12,14,16,18,20
set d. 4,8,12,16,20
