What characteristics of something that is cyclical

The angle of half past eight between the hour and minute hands of a clock is 255°.

Given that,

We have to find look for the smaller angles half past eight between the hour and minute hands of a clock.

We know that,

The clock is in circle.

A clock has 12 different parts. Between any two divisions, there is a 30° angle. Each division is then divided into 5 equal pieces, each of which is divided by an angle of 60° and equals 1 minute.

We know the total angle of the circle is 360°.

So, 12 hours is 360°.

Then 1 hours is

1 hour= 360/12=30°

So, 1 hour is 30°

60mins=1 hour

60 mins = 30°

1 min =30/60

1 min=1/2

So,

8 hour and 30 min

(8× 1 hour)+( 30×1 min)

(8×30)+(30×1/2)

240+15

255°

Therefore, The angle of half past eight between the hour and minute hands of a clock is 255°.

Answer:

0.282kg/m3

Step-by-step explanation:

density=mass/volume

mass=32.5kg

volume=lxbxh

volume=2.4mx60cmx80cm

convert 60cm and 80cm to m:

60cm=6m

80cm=8m

volume= 2.4mx6mx8m

volume=115.2m3

density=32.5/115.2m3

density=0.28211kg/m3

round to nearest three decimal places:

The equation that describes Joe’s monthly income is I = 500 + 20n. This function is Linear and discrete.

Joe makes each month = $500

The extra income per account he solicits = $20

No. of accounts he solicits = n

Income, I = 500 + 20n

It's a linear and discrete function.

A linear function in mathematics is one that has either one or two variables and no exponents. On a graph, it creates a straight line.

When the domain and range of a function are discrete sets of values rather than intervals, the function is said to be discrete.

After 25 minutes will both aquariums contain the same amount of water.

Given:

Aquarium a contains 4. 6 gallons of water. Louise will begin filling aquarium a at a rate of 1. 2 gallons per minute. Aquarium b contains 54. 6 gallons of water. Isaac will begin draining aquarium b at a rate of 0. 8 gallon per minute.

Let y be the minutes

A(y) = 4.6 + 1.2y

B(x) = 54.6 - 0.8y

Same amount of water:

A(x) = B(x)

4.6 + 1.2y = 54.6 - 0.8y

1.2y + 0.8 y = 54.6 - 4.6

2y = 50

divide by 2 on both sides

2y/2 = 50/2

The constant, k is $2500 and 7 months of work will be needed to earn $17,500.

According to the question,

We have the following information:

We have a table where months and the salary in dollars is given.

Now, the salary is increasing constantly with number of months.

So, we have the following expression:

9) Amount of dollars is directly proportional to number of months.

Dollars = k*months

2500 = k*1

k = 2500

10) Now, the amount given is $17,500.

So, we have:

k*months = 17,500

Months = 17500/2500

Months = 7

Hence, the constant, k is $2500 and 7 months of work will be needed to earn $17,500.

The measures of the following angles are:

∠6 = 124°,  ∠2 =124°,  ∠3 = 124° ∠5 = 56°,  ∠7 = 124° ∠1 = 56°

Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line (i.e. the transversal).

∠4 = 56° ( corresponding angles are equal)

∠1 =∠4 ( vertically opposite angles are equal)

∠1 = 56°

∠7 + 56° = 180 ( angles on a straight line sum up to 180°)

∠7 = 180 - 56

∠7 = 124°

∠7 = ∠6 ( vertically opposite angle are equal)

∠6 = 124°

∠3 = ∠6 ( alternate angles are equal)

∠3 = 124°

∠2 = ∠3 ( vertically opposite angle)

∠2 = 124°

∠5 = 56° ( vertically opposite angles)

The unknown angles are: ∠1 = 56° ∠2 = 124°, ∠3 = 124°, ∠4 = 56°, ∠5 = 56°, ∠6 = 124° ∠7 = 124°

The sum of two positive numbers is 120. The product of those numbers will be maximum if both numbers are equal to 60 and the maximum value is 3600.

Suppose we have a function f(x). At the extreme point (maximum/minimum), it holds:

      f ' (x) = 0

In the given problem, let the two numbers be a and b. Then,

a + b = 120 or

a = 120 - b   (equation 1)

f(b) = a x b = (120 - b) x b

f(b) = -b² + 120b

At the maximum point, the derivative with respect to b is zero,

f ' (b) = 0

-2b + 120 = 0

b = 120 / 2 = 60

Substitute b = 60 to equation 1,

a = 120 - 60 = 60

Hence, the two numbers that give maximal value of the product is 60 and 60. The product is 60 x 60 = 3600.

We can conclude that the maximum value of the product of those two numbers is 3600.

Let x be the overall number of cartons produced in a single day. due to the factory's daily production limit of 500 cartons.

Let P(x) denote the revenue generated by the sale of x cartons. Since a carton costs $25, the following follows;

P(x) = 25x

P(0) = 25(0) = 0 for x = 0

P(500) = 25(500) = 12500 when x = 500

The following are possible values for P(x);

0 ≤ P(x) ≤ 12500

The first quadrant that lies between the circle x² + y² =4 is 1.09587

The graph of x² +y² = 4 is a circle of radius 2, centered at (0, 0). In polar coordinates, this equation becomes simply r = 0.

The second equation requires a bit more work. To convert it to a polar equation, we

substitute, r cos θ for x and r sin θ for y:

r²cos ²θ + r²sin ²θ

   = 2r cos Ф

⇒r² = 2r cos θ

⇒r = 2 cos θ

This is the polar equation for a circle of radius 1, centered at the point (x, y) = (1, 0). (This can be seen directly from the original equation by completing the square, which results in the equation (x − 1)²+ y² = 1.)

To describe the region between the circles in polar coordinates, we can let θ range from 0 to π/2. Our values for r should range from the smaller circle to the larger one

Recalling again that x = r cos θ and dA = rdrdθ, our integral becomes

∫ ∫ₐ  x DA  = 8/3 - π/2

We can get a rough check of this answer as follows. The area of the region D is easily computed to be π/2. The average value of the function x in the region is somewhat less than 1, since D is thicker on the left. Doing these sorts of visual estimates can be very tricky, but let’s say the average value of x in D is about 0.70. Thus

∫∫ₐ x dA ∼=π/2· 0.70 ∼= 1.09956

Since 8/3 − π/ 2∼= 1.09587, this estimate agrees quite well with our answer.
