Long division is easier than you think. Here's how to solve this problem:
1. See how many times 36 can go into 66.
Multiply until you reach a number that is closest (or exact) to 66.
36 x 1 = 36; 36 x 2 = 72.
72 is over 66, so 2 doesn't work. Therefore, we'd put "1" in the first space on the shelf (right above the 6).
2. Subtract.
Now that we have "1" on the shelf, you need to subtract 36 by 66. We do this because 36 x 1 is 36. If it were the number "2" on the shelf, we'd subtract 72, and so on.
66 - 36 = 30.
3. See how many times 36 can go into 30.
Since it can't go into 30, we bring the 3 down (hence the arrow pointing down). The number is now 303.
4. See how many times 36 can go into 303.
I won't write it all out, but after multiplying 1-7 by 36, we find that the closest solution is 36 x 8 = 288.
We put "8" on the shelf, next to "1".
5. Subtract.
Now that "8" is on the shelf, we subtract 288 by 303, which gives us 15.
Since 36 cannot go into 15, and there are no more numbers we can drag down, your remainder is 15.
Your answer is:
36 R 15
The first two boxes under 663 should be filled with 36, the next three under that should have 303, the next three should have 288, and the final two boxes should have 15.

Which is the solution to the equation 8.25 + one-fourth w = 10.75? Round to the nearest hundredth if necessary.
Answer:
w=10
Step-by-step explanation:
8.25+1/4w=10.75
8.25+0.25w=10.75
0.25w=10.75-8.25
0.25w=2.5

Step-by-step explanation:
A pencil holder shaped like a triangular prisms height is 12 cm, and the volume of the pencil holder is 216 cm3. What is the area of the base of the pencil holder in square centimeters
Answer:
The area of the base of the pencil holder in square centimeters is 18 square centimeters
Step-by-step explanation:
The volume of a triangular prism is given as base area X height.
To get the base area, we can quickly shuffle the order of the terms to make sure that the base area is the subject of the formula.
Base area = volume of prism / height
Base area = 216/12 = 18 square centimeters
Therefore, the area of the base of the pencil holder in square centimeters is = 18 square centimeters

What Is The Difference Between 1+1 And 1x1?
Answer:
1+1=2 and 1x1= 1
Step-by-step explanation:
If you add something you take the first number and add it to the second one. If it is multiplication, you take the first number, and multiply by itself, so it would be 1 times itself (1) and it is kind of like 1+0 which equals 1. It doesn't sound like a lot, but when you get into Algebra and Pre-Algebra, etc. it does come along easier.

1+1=2 and 1x1= 1

Solve for theta to the nearest degree
Step-by-step explanation:
So first thing is to determine which trigonometric ratio we use here. Theta is adjacent to 5 and 8 is the hypotenuse, so we should be using Cosine.
So we set up the equation
cos θ = adj/hype
cos θ = 5/8
θ = [tex]cos^{-1} (5/8)[/tex]
θ=51.3178125...

The owner of a grocery store wants to mix two kinds of candy together to make 15 lb that he can sell for $5.00 per lb. He wants to use chocolate candies that he sells for $7.00 per lb and sugar candies that he sells for $2.00 per lb. How many pounds of each should the owner use?
_ pounds of chocolate candies
Answer:
9 pounds of chocolate candies
6 pounds of sugar candies
Step-by-step explanation:
x + y = 15
y = 15 - x
(7x + 2y) / 15 = 5
7x + 2y = 15 * 5 = 75
7x + 2 * (15 - x) = 75
7x + 30 - 2x = 75
5x = 45
x = 9
15 - 9 = 6
y = 6
9 pounds of chocolate candies and 6 pounds of sugar candies
The owner should use 6 pounds of the chocolate candies, and the other 9 pounds of the sugar candies.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given that owner of a grocery store wants to mix two kinds of candy together to make 15 lb that he can sell for $5.00 per lb.
He wants to use chocolate candies that he sells for $7.00 per lb and sugar candies that he sells for $2.00 per lb.
x + y = 15
y = 15 - x
(7x + 2y) / 15 = 5
7x + 2y = 15 x 5 = 75
7x + 2 (15 - x) = 75
7x + 30 - 2x = 75
5x = 45
x = 9
Now 15 - 9 = 6
y = 6
Threfore, we conclude that 9 pounds of chocolate candies and 6 pounds of sugar candies.

Mark uses 19 gallons of gas while traveling 399
miles at a constant rate in his car. How many
miles is Mark able to travel on 9 gallons of gas?
Answer:
189
Step-by-step explanation:
If mark uses 19 gallons to travel 399 miles, that means he was able to travel 21 miles per gallon.
We get this by taking 399 divided by 19.
So if mark travels on 9 gallons of gas and goes 21 miles per gallon, he will have traveled 189 miles.
We get this by taking 21 times 9
