Answer:
s = 1
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
sum the interior angles and equate to 540
39s + 129 + 79 + 145 + 148 = 540 , that is
39s + 501 = 540 ( subtract 501 from both sides )
39s = 39 ( divide both sides by 39 )
s = 1

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

Answers
Answer:
5/16
Step-by-step explanation:
Given that:
Fraction of claim = 5/8
Amount actually eaten = 1/2 of claim
Amount actually eaten = 1/2 * 5/8 = 5/16
Fraction of large pizza actually eaten is 5 /16
Hence, he ate, 5/16 of large pizza

A triangle has sides with lengths 8, 15, and 17.
Approximate the acute angles in this triangle.
Answers
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 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
The amount this week is $50.96

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
