So 12=total
7=blue
black=total-blue=12-7=5
black=5
1. 2/3 of 12 were taken out or 24/3 were taken out or 8 marbles were taken out
there is not enough info becasue it doesn't specify which ones were taken out
2. there is not enough info
3. not chosen=total-chosen=12-8=4 so 4 were chosen
Answer:209ft
Step-by-step explanation:
We let y be the unknown value, which is length of conduit.
200^2 + 60^2=y^2
40000 + 3600=y^2
43600=y^2
Square both side
y= sqrt(43600)
y= 208.8061 ft
y=209 ft
Answer: 720
Step-by-step explanation:
480 : 16 marked
480-16 = 464
They saw 464 unmarked squirrels and 16 marked squirrels
464/16 = 29
They saw 29 unmarked squirrels for every 1 makes squirrel
29 * 24 = 696
They would have seen 696 unmarked squirrels for the 24 marked squirrels.
696 + 24 = 720
Step-by-step explanation:
<h2>What is the rate of change of the line through (3, -5) and (-5, 3)?..........</h2>
Q = d - 12
q = 28 - d
d - 12 = 28 - d
d + d = 28 + 12
2d = 40
d = 40/2
d = 20 <== 20 dimes
q = d - 12
q = 20 - 12
q = 8 <== 8 quarters
