In every number, set every digit to zero that is not 8. Then look at the question again.
"Which of these lengths has 1/10 the value of 8.0?"
- A. 800
- B. 0.08
- C. 80
- D. 0.80
We hope the answer D is obvious to you.
... 0.80 = (1/10)×8.0
___
The appropriate choice is ...
... D. 209.86
Answer:
He needs 5x+56 ft
Step-by-step explanation:
To find how much of fencing he needs , we find the perimeter of the given figure
All sides are equal in a square
To find perimeter of the square we add all the sides
4 sides we have for the square
one side is x, so perimeter of square = x+x+x+x= 4x
Now we find perimeter of rectangle
Opposite sides of rectangle are equal
Here for rectangle we consider only three sides
because fourth side is common for rectangle and square
So perimeter of the rectangle (with 3 sides) = 28 +x+ 28 = 56+x
Total fencing = perimeter of square + perimeter of rectangle
4x + 56 + x= 5x+56
You can soustracte the first or the second one
and y cancel
x = 6
now you put 6 in x
you can take the first or the second one
6 - y = -2
6 - y = -2
y = -8
The least common multiple (LCM) of a set of numbers is the lowest value that all of the numbers can be divided by and have a result of a whole number.
In this case, the least common multiple is 21 because 21/7=3 and 21/21=1.
