Answer:

There are 60 hockey cards (1/4 of 240)

Step-by-step explanation:

1/3 of 240 is 80

1/6 of 240 is 40

1/4 of 240 is 60

80+40+60 = 180

240 - 180 = 60

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

<u>Step 1: Define</u>

Point (-1, 4)

Point (1, -1)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

Substitute [DF]: $\displaystyle d = \sqrt{(1+1)^2+(-1-4)^2}$
Add/Subtract: $\displaystyle d = \sqrt{(2)^2+(-5)^2}$
Exponents: $\displaystyle d = \sqrt{4+25}$
Add: $\displaystyle d = \sqrt{29}$

Which best describes the angles of some parallelograms? A. Four obtuse angles B. Four acute angles C. Two acute and two obtuse a

anyanavicka [17]

Some parallelograms have 2 obtuse and 2 acute angles.

Parallelograms may have all 90 degree angles as well. These are also called rectangles.

When you "bend" a rectangle it naturally forms 2 acute and 2 obtuse angles.
