A box contains blue, green and white beads. The ratio of the number of blue beads to the number of green beads to the number of white beads is 5:2:3. If there are 90 blue beads, how many beads there altogether?

There are 180 beads altogether

Step-by-step explanation:

5 units of blue beads=90

1 unit of beads= 90 ÷ 5

= 18

Total number of units= 5 + 2 + 3

= 10

10 units of beads(Total number of beads) = 18 × 10

= 180

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
