Answer:

a) The measure of the reference angle is 45°

Step-by-step explanation:

Reference angle:

   \sf \dfrac{7\pi }{4} \ is \ in \ the \ fourth \ quadrant.\\\\ \text{Reference angle = 2$\pi - \theta$}\\

                             \sf =2\pi -\dfrac{7\pi }{4}\\\\ =\dfrac{8\pi }{4}-\dfrac{7\pi }{4}\\\\= \dfrac{\pi }{4}\\\\=\dfrac{180}{4}\\\\

                             = 45°

The product the lies between__and__. 3×3/4?
cupoosta [38]
Saying 3/4 * 3 is the same thing as saying 3/4 of 3. Imagine you have 3 pies, each cut into 4 slices. That would be 3 * 4 = 12 slices of pie, right?
So when there's 12 slices, that would be 4/4 of the pies, since all the pieces are there.
To find out how many pies we would have with 3/4 of the pie left, we just need to multiply the original equation.

3 * 3/4 = 2 1/4

The product of those two numbers lies between 2 and 3.
Hope that helped =)

Answer:

blue question mark = –

Step-by-step explanation:

6(2x -1) uses the distributive property, which means that both 2x and -1 are multiplied by 6 when expanding the brackets.

6(2x - 1)

= (6 x 2x) + (6 x -1)

= 12x - 6

A cube with sides numbered 1 to 6 is rolled 300 times. What is the best prediction for the number of times that a 1 or 2 would b
Leno4ka [110]
The answer is A.

Divide 300 by the number of faces of a cube.

Since there are 6 faces on a cube then we divide it.

300 ÷ 6 = 50.

So exactly 50 times.

Hope this helps :)
