a man bought a cow and a calf for 990 dollars, paying 8 times as much for the cows as for the calf. what cost of each

Let x = the cost of the calf.  The cow costs 8 times as much, so it costs 8x.  Together they cost $990:

  x + 8x = $990

   9x=990

   x=990/9

   x=110

so the calf cost=110

and cow cost =880

Virtuoso answer.

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:

answer: 140

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
