Answer:
Use a proportion:
hours/cost = hours/cost
x/$1 = 5/$22
5/4 of hour
Step-by-step explanation:
12 - 5(3r + 2) = 17 |use distributive property a(b + c) = ab + ac
12 - 15r - 10 = 17
2 - 15r = 17 |subtract 2 from both sides
-15r = 15 |divide both sides by (-15)
r = -1
Answer:
41?
Step-by-step explanation:
It should be the same considering the fact that it is a reflection and line segment AB is 32 on both sides.
Answer:
C, just move the decimal back 5 spots
Because the actual dimensions of the board and the target are missing, let us supply the missing values.
Let:
radius of board = 6 inches
radius of target = 2 inches
Area of board = pi * r^2 = pi*6^2 = 36pi
Area of target = pi * r^2 = pi*2^2 = 4pi
Probability of hitting the target = 4pi / 36pi = 1/9
Therefore, there is a 1/9 chance of hitting the target on the board.
