Answer:
- See explanation below: either 0.984 cm or 0.85 cm depending on the complete question.
Explanation:
The question is incomplete and, thus, ambiguos.
There are two plausible interpretations: either each side of the prism has a leght of 4.92 cm, or the the units of the given measured is not cm but cm³ and 4.92 is the volume of the prism.
Considering the first option:
The best side length is the first decimal number that divides exactly 4.92cm
- That is 4.92/5 = 0.984 cm
Considering the second option
The correct question would be "If you fill a 4.92 cm³ prism with cubes who’s sides lengths are less than 1 cm what size would be the best"
The best size of the sides lentgths is one that occupies the greatest part of each length.
Assume the prism is a cube. Then, the legth of each side is:
The greatest decimal number that divides 1.70 exactly is:
- 1.70cm/2 = 0.85cm

(2) x = 10 / 2
Hope this helped!
We'll use the variable x
Equation involving multiplication:
2x=10
We'll solve it to make sure it works. Since the solution has to be five, we'll plug that in for x
2×5=10
10=10
This works, so we can move on.
Equation involving division:
10÷x=2
Again, we'll solve it to make sure it works, plugging in 5 for x
10÷5=2
2=2
This equation works as well.
The two equations are
2x=10
and
10÷x=2

Answer:
0.111<1.001
1.11 > 1.01
Step-by-step explanation:
To identify the greater number from decimal number.
Rule: First we check number or digits before decimal.
- If digit is greater than number is greater than.
- If digit is smaller then number is smaller
- If digit is same then check digit after decimal.
# 0.111 or 1.001
In 0.111 digit before decimal is 0
In 1.001 digit before decimal is 1
As we know 0<1
So, 0.111<1.001
# 1.11 or 1.01
In 1.11 digit before decimal is 1
In 1.01 digit before decimal is 1
1 = 1 , So test fail. Now check digit after decimal.
In 1.11 digit after decimal is 1
In 1.01 digit after decimal is 0
As we know 1>0
So, 1.11 > 1.01

The given pictures show the remaining slices in each pie in gray.
What is the fraction?
In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Number of slice ate in pumpkin pie = 2/8
Number of slice ate in pecan pie = 3/8
Total number of slice pie ate
= 2/8+3/8
= 5/8
The portion of the pies Dakota’s family ate on Thanksgiving is 5/8. Therefore, option B is the correct answer.
