Answer:
36 inches
Step-by-step explanation:
The ratio is L:W = 4:3 = 48:?
if you divide 48 by 4 you get 12. So now do 12 times 3 to get 36! Whatever you do to one ration do the same to the other, I like to remember it that way.
Answer:
Step-by-step explanation:
so the question lets us know 3 things:
1) Sarah has a 27 ft pipe
2) she cuts 6 ft off
3) she cuts remaining pipe into 7 equal sections
what we don't know from the question is how big each of those 7 sections were. To form the equation we do this.
Since we know Sarah has 27 ft of pipe that would be our answer of the equation.
Sarah also removed 6 ft and the rest of the pipe she cut up into 7 small sections of equal length. since we don't know the length of the 7 smaller sections we will use the variable X to represent the length. this means that 6ft + 7x (X is the length of the pipes, and we multiply by 7 since there are 7 of them) must equal Sarah's total length of 27ft, therefore meaning our education would be
to solve for how long each pipe was, we need to solve for X by rearranging the equation as shown bellow.
Answer:
Step-by-step explanation:
There are 9 combinations since there is R, Y, B- 3 times it adds up to 9 combinations.
Answer: B) A large bottle costs $12, and a small one costs $8.
Where L is how many large bottles have been sold, and is how many small bottles have been sold.
In order to find out how much money the large bottle and small bottles cost, we must solve the system of equations.
Step 1: Subtract 3S from both sides
Step 2: Divide both sides by 44.
Step 3: Replace L for
Step 4: Simplify
Step 5: Subtract 108 from both sides
Step 6: Divide both sides by -2.5
Step 7: Replace S for 8
Step 8: Divide both sides by 4
Step 9: Subtract 6 from both sides
Answer:
241.5cm³
Step-by-step explanation:
Volume of the glass = Volume of the cuboid - Volume of the cylinder
Volume of the cuboid = Length * width * height
Volume of the cuboid = 8cm * 4cm * 10cm
Volume of the cuboid = 320cm³
Volume of the cylinder = πr²h
Radius r = 5/2 = 2.5cm
height = 4cm
Volume of the cylinder = 3.14(2.5)²*4
Volume of the cylinder = 78.5cm^3
Volume of the glass = 320 - 78.5
Volume of the glass = 241.5cm³
