Answer:

Step-by-step explanation:

A.

Income: 600,000 + 600,000 + 400,000 =

$1,600,000

Expenses: 400,000 + 500,000 + 600,000 =

$1,500,000

B .

Expenses: 600,000 + 700,000 =

$1,300,000

Income: 400,000 + 600,000 =

$1,000,000

1,300,000 - 1,000,000 = $300,000

C.

Expenses:

Year 1: 400,000

+ 100,000 =

Year 2: 500,000

+ 100,000 =

Year 3: 600,000

+ 100,000 =

Year 4: 700,000

+ 100,000 =

Year 5: 800, 000

Adds 100,000 each year not 200,000.

D.

Income:

Year 1: 600,000 x 2 =

$1,200,000

Year 5:

$900,000

Answer:

The combined expenses in Years 3 and 4 were $300,000 more than the combined income of Years 3 and 4.

Step-by-step explanation:

The combined income in years 1, 2, and 3 is $1,400,000 and the combined expenses in the same years is $1,500,000; so number 1 is incorrect.

Expenses have increased $100,000 each year over the last 5 years. Year 1 = $400,000 , Year 2 = $500,000 , Year 3 = $600,000 , Year 4 = $700,000 , Year 5 = $800,000. So number 3 is incorrect.

Year 1's income was $600,000 and Year 5's income was $900,000. Twice Year 1's income would have been $1,200,000. So number 4 is incorrect.

Can someone please help me find the measure of the exterior angle.

Answers

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  because they are supplementary angles

k = 140°

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°  

k = 140°
