Fill in the blank with always, sometimes, or never. if there is not enough information, choose inconclusive. who planes intersect to form a line.

Always

Step-by-step explanation:

We are required to fill in the blank for the given statement,

' Two planes intersect to form a line.'

Now, as we know that a plane resembles a parallelogram.

When two parallelograms intersect, the intersecting region is always a line.

Hence, we get that,

'Two planes intersect to ALWAYS form a line.'

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
