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.

Answer:

a) The blue whale has about 200 times more mass.

Step-by-step explanation:

A cow has a mass of 9 × 10^2 kilograms, and a blue whale has a mass of 1.8 × 10^5 kilograms.

The blue whale is about \frac{1.8\times10^{5}}{9\times10^{2}} times more than cow.

= \frac{180000}{900}

= 200

Hence, the answer is a) The blue whale has about 200 times more mass.

Solve the following system using the substitution method.
Liono4ka [1.6K]
X = (15 - 8y)/9

-5[(15 - 8y)/9] + 12y = -107

(-75/9) + (40/9) + 12y = -107

y = -8.59

x = [15 - 8(-8.59)]/9

x = 9.3
(x,y) = (9.3, -8.59)
