I'm guessing 10 days, since you lost a bit more than half of the workers, and it would take longer for the job to get done.
The <em><u>correct answer</u></em> is:
They had no placeholding zero.
Explanation:
Our numbering system is one of few known to have a numeral for zero. Mayans did; however, theirs never traveled the world. Babylonians were thought to have a mark for nothing, but it was more for punctuation than numerals. Neither the Romans nor the Egyptians had a number for 0 either.
Zero is key to our system of numbering, as it helps us hold place as well as representing nothing. Without it, it is easier to represent problems in words.
L = 16.51
Get variable onto one side of equation and simplify:
(−7.4 )+ L = 9.11
L = 9.11 + 7.4
L = 16.51
9 x _ = 162 (ABCD) 162 divided by 9 = 18
9 x 18 = 162
6 x 18 = 108ft2
Due to the length being identical, if you work out the width and see what it can be timsed by to get the Area what you times the width with is your Length and as the length is the same, you times 6 by 18 which gives to the area of 108 ft2
Answer:
C. 4
Step-by-step explanation:
-1/2 * (-8)
Replace -8 with a fraction
-1/2 * -8/1
Multiply the numerators
-1 * -8 = 8
Multiply the denominators
2*1 =2
Put the numerator over the denominator
8/2 = 4
