* An ant is crawling around this cube. The cube is made of wire. Each side of the cube is 3 inches long. (Those sides are called

edges.) Points A and B are vertices of the cube.
What is the least distance the ant would have to crawl if it starts from point A, crawls along every edge of the cube, and returns to point A?

PLEASE EXPLAIN

A cube has 12 edges and each edge is 3 inches. If the ant only crawls on the edges it would be a distance of 36 (3*12)

Which equation represents a line that passes through (-2, 4) and has a slope of 2/5
Ulleksa [173]

Answer:

The equation of line is 5(y-4) = 2( x+2)

2 x-5 y+24=0

Step-by-step explanation:

<u>Step 1:-</u>

Given slope is m = \frac{2}{5} and passes through (-2,4)

y-y_{1}= m(x-x_{1} )

y-4 = \frac{2}{5}(x-(-2))

5(y-4) = 2( x+2)

2 x-5 y+24=0

In ΔUVW, w = 3 inches, ∠W=23° and ∠U=73°. Find the length of u, to the nearest 10th of an inch.
kirza4 [7]

Answer:

<h2>7.4inches</h2>

Step-by-step explanation:

Check the attachment for the diagram. Sine rule will be used to get the unknown side of the triangle.

According to the rule;

\frac{u}{sinU} =  \frac{v}{sinV} = \frac{w}{sinW}\\\frac{u}{sinU} = \frac{w}{sinW}

Given w = 3 in, ∠W=23° and ∠U=73°, on substituting into the equation above to get u we have;

\frac{u}{sin73^{0} } = \frac{3}{sin23^{0} }\\usin23^{0} = 3sin73^{0}\\u = \frac{3sin73^{0} }{sin23^{0} }\\u = \frac{2.87}{0.39} \\u = 7.358\\u = 7.4in

The length of u is 7.4inches to nearest 10th of an inch

A machine wheel spins at a rate of 500 revolutions per minute. If the wheel has a diameter of 80 centimeters, what is the angula
solmaris [256]

Answer: 3,140 radians per minute.

Step-by-step explanation:

We know that the wheel does 500 revolutions per minute.

This is called the frequency of the wheel, and this is written as:

f = 500 rev/min = 500 RPM

The angular speed (or Angular velocity) is written as

ω = 2*pi*f

And this quantity is in radians/unit of time.

where pi = 3.14

then:

ω = 2*3.14*500 (rev/min)*(rad/rev) = 3,140 rad/min

This means that the angular velocity  (or angular speed) is 3,140 radians per minute.
