Answer:

42.78 inches

Step-by-step explanation:

The anount of rainfall for the past three months are

15.82 inches

17.4 inches

9.56 inches

Therefore the total amount of rainfall for the three months can be calculated as follows

= 15.82+17.4+9.56

= 42.78

Hence the total rainfall for three months 42.78 inches

Answer: 504 hours.

Step-by-step explanation: I am assuming it says, use a table not a lable.

Well, I can't make a table, so I will tell you where to put everything in a table.

We start with placing one day, one day is 24 hours. One day goes on the top, 24 hours goes on the bottom. Then, we know there are 7 days in a week, so we jump ahead, we multiply 24 by 7 and 1 by 7.

24 x 7 = 168 and 1 x 7 = 7

So for every week, it is 168 hours. Now we need to find three weeks. So we multiply 7 x 3 to get the days. which is 21. Now we need to multiply the hours by  the 3 weeks. So we multiply 168 by 3 which is 504.

So 504 hours are in 3 weeks.

Answer:

2,000

Step-by-step explanation:

The computation of the price that should be sold for making 25% profit is shown below:

Let cost price be x

Now the equation would be

(1,920 - x) ÷ x × 100 = (x - 1,280) ÷ x × 100

1,920 - x = x - 1,280

2x = 3,200

x = 1,600

Now the sale price would be

= 1,600 × 1.25

= 2,000

Answer:

The domain of given function is: [-7,7]

Step-by-step explanation:

Graphs can be used to determine the domain and range of a function.

On a graph, the values across the x-axis are domain and across y-axis are the range.

In the given graph, we can see that the graph starts from x=-7 and ends at x=7. The filled circle at both ends of the graph indicate that the values 7 and -7 are also included in the domain.

Hence,

The domain of given function is: [-7,7]

Answer:

1. The volume of the pile is 4,399.7719 m^3

2. The number of sanders to be filled from a pile is 638

Step-by-step explanation:

Here, we firstly would calculate the volume of the pile

Mathematically, that will be;

V = 1/3 * pi * r^2 * h

from the question, h = 14.2

Mathematically, r = d/2

r = 34.4/2 = 17.2 m

So the volume will be:

V = 1/3 * 3.142 * 17.2^2 * 14.2

V = 4,399.7719 m^3

To find the number of sanders to be filled,

we simply divide the volume obtained by the volume a sander can take

That will be;

4,399.7719/6.9

= 637.6 which is 638

Here Is Your Answer i^31

Answer:

15 females say they use their phone less than an hour a day

36 - 15 = 21 males that use their phone less than an hour a day

(equation above is the total number of students that use their phone less than an hour a day, with the 15 females that do being subtracted from it. that will leave the number of males that use their phone less than an hour a day, which is your answer.)

Recall that

tan²(x) + 1 = sec²(x)

for all x ≠ (2n + 1) 90°, where n is any integer. (That is, whenever x isn't an angle that is an odd multiple of 90°.)

Then

tan²(Φ) + sec²(Φ) = 3

tan²(Φ) + (tan²(Φ) + 1) = 3

2 tan²(Φ) + 1 = 3

2 tan²(Φ) = 2

tan²(Φ) = 1

tan(Φ) = ±√1

tan(Φ) = 1   or   tan(Φ) = -1

Φ = tan⁻¹(1) + n 180°   or   Φ = tan⁻¹(-1) + n 180°

Φ = 45° + n 180°   or   Φ = -45° + n 180°

The first family of solution is the set of angles

{…, -315°, -135°, 45°, 225°, 405°, …}

and the second family is the set

{…, -405°, -225°, -45°, 135°, 315°, …}

(showing the solutions for n = -2 to n = 2)

You can condense the solution set into one family by noticing each angle is 45° plus some multiple of 90°, so that

Φ = 45° + n 90°

If you're looking for solutions in a given range, such as 0 ≤ Φ < 360°, then

Φ = 45°, 135°, 225° or 315°
