Answer:
a) The blue whale has about 200 times more mass
Step-by-step explanation:
(blue whale mass)/(cow mass) = (1.8×10^5 kg)/(9×10^2 kg)
... = (1.8/9)×10^(5-2)
... = 0.2×10^3
... = 200
The blue whale has about 200 times as much mass as a cow.
I'm guessing it is 5/8 than 2/8 and last 1/8 it HAS to be what i just said
Answer:
Perimeter = 10 + 2√5 = 14.47
Explanation:
Vertices X(−1, 3), Y(3, 0), and Z(−1,−2).
We have three points, We need to find out the distance between them.
we know that the formula to calculate the distance between two points.
D = √[(x₂-x₁)²+(y₂-y₁)²]
Distance between X & Y
XY = √[(3-(-1))²+(0-3)²] = √(16+9) = √25 = 5
Similarly,
YZ = 2√5
ZX = 5
XY =5
Now find the perimeter
In order to find the perimeter, we will add all the sides together.
perimeter = XY + YZ + ZX
Perimeter = 5 + 2√5 + 5
Perimeter = 10 + 2√5 = 14.47
