Answer:
Step-by-step explanation:
Set up two equations with the information given-- and things you know from experience: a penny is worth 1 cent and a nickel is worth 5 cents. $ 2.38 is 238 cents (so you can eliminate decimals for now)
Put those values into an equation about the total value:
p + 5n = 238
and you know the total number of coins is 66.
p + n = 66
get a value for p by "solving" (subtract n from both sides)
p = 66-n
Substitute that value for p in the first equation. Then solve.
(66 -n) + 5n = 238
4n = 238-66 Then isolate n by dividing both sides by 4
n = 172/4
n = 43 Substitute that in the second equation, then solve for p
p + 43 = 66 p = 66 - 43
p = 23
So Chuck has 23 pennies and 43 nickels
This is a problem of fundamental counting principle. In a
sequence of events, the total possible number of ways all events can performed
is the product of the possible number of ways each individual event can be
performed. So here there is one car in each place so there 4 possible
cars to get the 1st place, 3 possible car for the 2nd
place, 2 possible cars for 3rd place and 1 for the 4th
place. The 4x3x2x1 = 24 different order
You have to distribute the 3 first then combine like terms and divide to get n by itself so n=1/2
Answer:
925 cubic inches
Step-by-step explanation:
Miguel has a toolbox that measures 18 1/2 inches by 12 1/2 inches by 4 inches. Fill in the formula to find the volume of the toolbox
The toolbox is shaped as a Rectangular prism
The volume of a rectangular prism = Length × Width × Height
Hence,
Length = 18 1/2 inches
Width = 12 1/2 inches
Height = 4 inches
Volume of the toolbox =
18 1/2 inches × 12 1/2 inches × 4 inches
= 925 cubic inches
