A fan has five equally spaced blades. Suppose you line up two fans directly on top of each other. What is the least number of degrees that you can rotate the top fan so that the two fans are perfectly aligned again?

A fan has 5 equally spaced blades.
A. 120°
B. 60°
C. 90°
D. 72°

Answer:

63 cm^2.

Step-by-step explanation:

Total Area = area rectangle + area of triangle on right + area of triangle at the top.

= 6 * 8 + 1/2 * 1 * 6 + 1/2 * 8 * 3

= 48 + 3 + 12

= 63 cm^2.

Step-by-step explanation:

4x and 6x sit on a straight line therefore must equal to 180°

4x+6x = 180° (∠'s on str. line)

10x = 180

x= 180/10

x= 18

Then we need to find ∠UYV

∠UYV = 4x

=4(18)

=72°

So ∠UYV = 72°

In general, a variable to any even power is a perfect square.

So for example, x² is a perfect square and so is y¹⁴.

A common made by students is not in factoring the difference of two squares, but just failing to recognise that the difference of two squares exist.

It will also help to review your perfect squares

for the numbers between 1 and 16.

The fraction of 33 kg as a fraction of 4 tonnes is 33/4000.

The same property is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other length unit instead of miles.

For example, inches, centimeters, and miles are all measures of distance.

Given:

Amount= 33 Kg

We have to convert Kg into Tones

We know, 1 tonne= 1000 Kg

So,4 tonee = 4 x 1000

                = 4000 Kg

Thus, 33 kg as a fraction of 4 tonnes.

= 33/4000

Step-by-step explanation:

deltamath gave me the answer

The length of w is 54 cm.

One of the six mathematical functions used to express the side ratios of right triangles, the trigonometric function includes the sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). The figure shows these six trigonometric functions in respect to a right triangle. Surveying, engineering, and navigation issues where one of a right triangle's acute angles and the length of a side are known but the lengths of the other sides need to be determined can be solved with ease using trigonometry.

As per the given data:

x = 41 cm

v = 17 cm

∠W = 134°

To find the length of w:

From the cosine law:  [tex]cos(W) = \frac{x^2 + v^2 - w^2}{2xv}[/tex]

[tex]w = \sqrt{x^2 + v^2 - 2xvcos(W)}\\w = \sqrt{(41)^2 + (17)^2 - 2(41)(17)cos(W)}\\w = \sqrt{1681 + 289 + 968.35} = \sqrt{2938.35}\\w = 54 \:cm[/tex]

Hence, the length of w is 54 cm.

Answer:

  54°, 54°, 72°

Step-by-step explanation:

Your ratios total 3+3+4 = 10 units, so each unit must stand for 180°/10 = 18°.

Then the angles are found by multiplying the ratio values by 18°.

  3 : 3 : 4 = 54° : 54° : 72°
