Your firm has net income of $329 on total sales of $1,340. Costs are $740 and depreciation is $130. The tax rate is 30 percent. The firm does not have interest expenses. What is the operating cash flow?

Answers

Answer:

Net operating cash flow= $459

Step-by-step explanation:

Giving the following information:

Your firm has net income of $329 on total sales of $1,340. Costs are $740 and depreciation is $130. The tax rate is 30 percent. T

To calculate the operating cash flow, we need to use the following structure:

Sales= 1,340

Costs= (740)

Gross income= 600

Depreciation= (130)

EBIT= 470

Tax= (470*0.3)= (141)

Depreciation= 130

Net operating cash flow= $459

A triangle has sides with lengths 8, 15, and 17.
Approximate the acute angles in this triangle.

Answers

62° and 28° i used a calculator

Pythagoras is the sum of the square of two sides is equal to the square of the longest side. Then the acute angle of the given triangle is 28.07 degrees.

What is a right-angle triangle?

It is a type of triangle in which one angle is 90 degrees and it follows the Pythagoras theorem and we can use the trigonometry function.

A triangle has sides with lengths 8, 15, and 17.

By Pythagoras theorem, we have

  H² =  P² + B²

 17² = 8² + 15²

289 = 64 + 225

289 = 289

The dimension of the triangle satisfies the Pythagoras theorem. Hence the triangle is a right-angle triangle.

Then the acute angle will be

[tex]\rm \theta =Sin ^{-1} \dfrac{8}{17}\\\\\theta = 28.07^o[/tex]

Thus, the acute angle of the given triangle is 28.07 degrees.

More about the right-angle triangle link is given below.

The average grade Jared received on 4 tests was 94. If he drops his lowest test grade of 85, what will his new average be?

A.72.75
B.76
C.89.5
D.97

Pls help TT

Answers

Answer:

total points on the 4 tests- 94x4= 376

376- 85= 291

291/3= D. 97

Answer:

D. 97

Step-by-step explanation:

x = sum of 4 test grades Jared received

[tex]\frac{x}{4} = 94[/tex]

x = 376

If he drops lowest test grade of 85, then subtract 85 from Jared's sum of all test grades:

x - 85 --> 376 - 85

= 291

Now that one of his test grades are not considered, this means there are only 3 test grades to consider.

291 must be divided by 3 to get the average:

[tex]\frac{291}{3}[/tex] = 97

The answer is D) 97

The regular price of a video game is $59.,95. This week it is on sale for 15% off. What does the game cost this week (before taxes)

Answers

Answer: $50.96

Step-by-step explanation:

The regular price of a video game is $59.95 and we are told that this week it is on sale for 15% off.

The game cost this week before taxes will be:

= 59.95 - (15% × 59.95)

= 59.95 - (0.15 × 59.95)

= 59.95 - 8.9925

= $50.9575

= $50.96
