Ill give brainliest meee an elephant weighs 1.1 × pounds. a giraffe weighs 2.1 × pounds. how much more does the elephant weigh than the giraffe? a. 1.0 × pounds b. 8.9 × pounds c. 1.0 × pounds d. 8.9 × pounds

B

Step-by-step explanation:

1) First find the weight of the elephant: 1.1 * 10^4 = 11,000

2) Then find the weight of the giraffe: 2.1 * 10^3 = 2,100

3) Then subtract the weight of the giraffe from the weight of the elephant

11,000 - 2,100 = 8,900

4) And there is your answer 8.9 * 10^3 = 8,900

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5
