Answer:
The first number is 12, the second is 15.
Step-by-step explanation:
One equation to solve this would be n+(n+3)=27
n+(n+3)=27
Simplified: 2n+3=27
2n+3=27
2n+3-3=27-3
2n=24
2n÷2=24÷2
n=12
When you plug <em>n </em>into the equation, you get 12+(12+3)=27
12+(12+3)=12+15
12+15=27
So, the first number is 12 and the second is 15

Answer:
- 113.04, 4, 452.16
- 78.5, 11, 863.5
- 153.86, 10, 1538.6
Step-by-step explanation:
When calculations are repetitive, I like to let a calculator or spreadsheet do them. Here we have used the formula for the base area:
B = πr² = 3.14×r²
In the second figure, the radius is half the diameter, so is 5 units.
The table in the attachment lists the base area B, the height h (from the figures), and the volume V. These are the values that you need to drag and drop to the boxes in your problem.
V = 113.04 · 4
V = 452.16 units³ . . . showing how the numbers are used in the first figure
Answer:
False
Step-by-step explanation:
The difference of the first two numbers is 4-2 = 2. The difference of the next pair is -9-4 = -13, a different value. There is no common difference between these numbers, so the sequence is NOT ARITHMETIC.
It could be 443, try simplifying to the nearest hundreaths, hope this helps!
