I’ll give you a brainiest and a thanks. A worker bee has a mass of 0.00011 kg.
Choose the best approximation of the mass of a worker bee.
Choose 1
A: 1 • 10^-4 kg
B: 1 • 10^-3 kg

An African elephant has a mass of 8139 kg.
Choose the best
Approximation of the mass of an African elephant.
Choose 1
A: 8 • 10^3 kg
B: 8 • 10^4 kg

1). Option (A)

2). Option (A)

Step-by-step explanation:

1). A worker bee has the mass = 0.00011 kg

   In scientific notation we can convert the mass of bee as,

   0.00011 =

                 =

   Since 1.1 ≈ 1,

   Therefore, 1.1 × 10⁻⁴ ≈ 1 × 10⁻⁴ kg

   Option (A) is the answer.

2). An African elephant has a mass = 8139 kg

    In scientific notation,

    8139 = 8.139 × 10³

    Since, 8.139 ≈ 8

    Therefore, 8139 kg = 8.139 × 10³ kg

    Option (A) is the answer.

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
