Answer:
3
Step-by-step explanation:
The surface of the rectangular prism is 18, because you just add up all of your sides
Ratio of perimeters is a : b:
21:18
Which reduces to: 7:6
Ratio of areas is a^2 : b^

2:
"7 ^2: 6^2"
Which simplifies to: 49:16
The answer is 7:6 and 49:36
Answer:
a) 416/100 = 4.16
b) 46/10 = 4.6
c) 406/100 = 4.06
Step-by-step explanation:
a) 4 + 16/100 = 4(100/100) +16/100 = (400 +16)/100 = 416/100 = 104/25
4 + 16/100 = 4 +0.16 = 4.16
__
b) 4 + 6/10 = 4(10/10) +6/10 = (40 +6)/10 = 46/10 = 23/5
4 +6/10 = 4 +0.6 = 4.6
__
c) 4 +6/100 = 4(100/100) +6/100 = (400 +6)/100 = 406/100 = 203/50
4 +6/100 = 4 +0.06 = 4.06

<em>Comment on place value</em>
Since you're familiar with the decimal place-value number system, you know that digits in the ones place are multiplied by 1; digits in the tenths place are multiplied by 1/10 or 0.1; and digits in the hundredths place are multiplied by 1/100 or 0.01. These same multipliers can be represented as powers of 10: 10^0, 10^-1, 10^-2, respectively.
Answer:
8 classes
Step-by-step explanation:
Given



Required
The number of class
To calculate the number of class, the following must be true

Where k is the number of classes
So, we have:

Take logarithm of both sides

Apply law of logarithm

Divide both sides by log(2)


Round up to get the least number of classes
