Answer:
100 has <u>5</u> factor pairs, so that many different rectangles can be drawn. 15 only has <u>2</u> factor pairs, so only that many different rectangles can be drawn.
Explanation:
there are 5 pairs of whole numbers that multiplied together will be 100:
- 100 x 1 = 100
- 50 x 2 = 100
- 25 x 4 = 100
- 20 x 5 = 100
- 10 x 10 = 100
while there are only 2 pairs of whole numbers that multiplied together will be 15:
- 15 x 1 = 15
- 3 x 5 = 15
60ml / resin
x / 19 resin
Cross multiply
60(19) = x
1140 = x
Therefore you need 1140ml of glue for 19 resin
Right angles are usually always 90 degrees, then if you are looking at right triangles, you have 45,45,90 degree triangles and 30,60,90 triangles
