Answer:
Step-by-step explanation:
the shape is made up of 2 circles and one box add the 3 areas up
circle area = 
3.14*
= 50.24
50.24*2 =100.48
box, box, pit now :P ooh I was thinking formula one racing, ( i've been watching that lately) anyway
box = 8*8 = 64
total = 164.48 is that an option? hmm, yes the bottom two choices.. now the perimeter . the perimeter is made up of the 2 circles
the circumference of a circle is 2r
2**r
2**4 =25.1327 that's one whole circle , multiplied by 2 , I can see , by math in my head that's about 50.26
sooo
the 3rd choice looks good :)
Answer:
Ounces of green paint needed = 13.8
Step-by-step explanation:
Blue paint : green paint = 25 : 115
how many ounces of green paint should she mix with 3 ounces of blue paint?
Let
Ounces of green paint needed = x
Blue paint : green paint = 3 : x
Equate both ratios
25 : 115 = 3 : x
25/115 = 3/x
25 * x = 115 * 3
25x = 345
x = 345/25
x = 13.8 ounces
Ounces of green paint needed = 13.8
Answer:
