Answer:
9.55 in
Step-by-step explanation:
The formula for the circumference of a circle (or the circum. of a basketball) is C = πd, where d is the diameter.
Here C =30 in = πd, so
d = (30 in) / π
= 9.55 in, approx.
Remove unnecessary parenthesis, and combine like terms
(3+i) + (5-2i)
3+i + 5-2i
8+i
you added 3+5 which is 5 and i-2i which is "i"
hope this helps.
Answer: 25 nickels
Step-by-step explanation:
EQUATIONS:
quantity: n + d = 63
value: 5n + 10d = 505
-------------------------
Divide thru the 2nd equation by 5 to get:
n + 2d = 101
----------------
Subtract that from the 1st equation:
-d = -38
d = 38 (# of dimes)
---------------
Substitute that into n+d=63 to solve for "n":
n + 38 = 63
n = 25 (# of nickels)
According to the FIFO method, the earliest sweaters are the ones that are sold off first, so if we have 24 remaining, 15 were bought in September (at $45 each) and the last 9 were from June (at $38 each). Then we calculate the total value by:
15($45) + 9($38) = $1,017
The value of the inventory is $1,017.
