Mathematics

ira [324]3 years ago

Since the average of 6 tests is 6, and we know that the average is found by dividing the total score by the number of tests, we can just multiply the average by the number of tests to find the total score. Doing this, we get 82 * 6 which simplifies to 492.

A quadrilateral WXYZ contains wxy where measure of wxy=92 degrees. Once rotated 270° about the origin and translated 2 units up,
Marianna [84]

Answer:

C. 92 degrees

Step-by-step explanation:

Given that the \angle{wxy}=92° which is one of the angles of the quadrilateral WXYZ

The quadrilateral is first rotated by 270° about the origin and then translated 2 units up, the new position of the quadrilateral is W'X'Y'Z'.

The shape of the quadrilateral is remained unchanged due to rotation and translation, so all the angles of the final quadrilateral W'X'Y'Z' is the same as the angles of the given quadrilateral WXYZ.

So,\angle{w'x'y'}= \angle{wxy}

By using the given value,

\angle{w'x'y'}= 92°

Hence, option (C) is correct.

In circle P, if the radius is 3 cm, what is the length of arc AD?
umka21 [38]

Hello there.

We have for a circle that:

\ell=\alpha r

Where:

\ell is the measure of the arc

\alpha is the measure of the angle (radians)

r is the radius of the circle


In our case, we have \alpha = 120^\circ = \dfrac{120}{180}\pi = \frac23\pi ~rad

We have r = 3 cm, then:

\ell = (\frac23\pi )(3\ cm)\\ \\ \boxed{\ell = 2\pi~cm}

If a printer prints 28 copies in 1 minute how many would it print in 3 minutes and 45 seconds?
Wittaler [7]

3minutes 45 seconds = 3 45/60 = 3.75 minutes

28 copies/ 1 minute = x copies/3.75 minutes

using cross products

28 * 3.75 = 1 * x

105 = x

We can print 105 copies in 3 3/4 minutes
