Ratio
80c: $8
I need to solve ratios but I can’t solve this one help

1000:1

Step-by-step explanation:

100dollars =1cent

8000dolars=80cent

Therefore,

80cent:$8

8000/8

1000:1

1 : 10

Step-by-step explanation:

We require both parts of the ratio to be in cents

$1 = 100c, hence $8 = 8 × 100 = 800c, thus

80c : $8

= 80 : 800 ← divide both parts by 10

= 8 : 80 ← divide both parts by 8

= 1 : 10

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
