Answer:

1564.42 mph

Step-by-step explanation:

Let a = Object A's speed

     b = Object B's speed

a = b + 1500

a/85000 = b/3500

Let's make subtract 1500 from both sides of the first equation

a = b + 1500

- 1500  - 1500

b = a - 1500

Cross multiply the second equation

3500a = 85000b

Plug in the new b into this new equation

3500a = 85000(a - 1500)

3500a = 85000a - 127500000

Subtract 3500a and 127500000 from both sides

3500a = 85000a - 127500000

- 3500a  - 3500a

0 = 81500a - 127500000

+ 127500000    + 127500000

127500000 = 81500a

Divide both sides by 81500

127500000/81500 = 81500a/81500

a = 1564.4171779141104

In horizontal analysis the percent change is computed by: a. Subtracting the analysis period amount from the base period amount.
Sonja [21]

Answer:

  b. Subtracting the base period amount from the analysis period amount, dividing the result by the base period amount, then multiplying that amount by 100%

Step-by-step explanation:

A percentage change can be computed from ...

  ((new amount) -(old amount))/(old amount) × 100%

This best matches the description of choice B.

_____

<em>Comment on the answer</em>

The formula offered in the question will show the "percent change" from 100 to 103 as 3. It is not 3; rather, it is 3%. The final multiplication must be by 100% in order to arrive at the proper number.

If BE−→− bisects ∠ABD and m∠ABD = 66°, find m∠ABE
Monica [59]

Answer:

m∠ABD = 132 °

Step-by-step explanation:

m∠ABE = m∠DBE

and

m∠ABD = m∠ABE + m∠DBE

Because m∠ABE = 66°, therefore m∠DBE = 66°, so that

m∠ABD = 66° + 66° = 132°
