I am assuming that we have to round the numbers to the nearest tens.
When rounding off numbers, if the number is more than half, then you round it up for example, if the number is 15 and you want to round it off, you round it up to 20. But if the number is 14 you round is down to 10
Therefore, 33 would be rounded off to 30 as 3 is less than 5 in the ones place if you get what I mean.
As for 89, you would round it up to 90 as the 9 in the ones place is more than 5.
Therefore the sum of 90 and 10 is 100.
Hope this helps!
Answer:
1 : 6 . . . . or 1/6
Step-by-step explanation:
We know 1 foot is 12 inches, so 5 feet is 5·12 = 60 inches. Zachary's scale factor is ...
drawing size : actual size = 10 inches : 60 inches = 1 : 6
This can also be written as the fraction 1/6.
0.3 is the decimal of 45/150
To change fraction into decimal you need the divide the denominator by the numerator.
So 150 divided by 45 is 0.3.
The answer is D. 12
4, 3 and 2 are all factors of 12 (least common denominator)
Answer:
16 2/3 %
Step-by-step explanation:
Since the price went down, we are find the percent decrease.
Percent decrease = (original price - new price)/ original price
= (90 - 75)/90
=15/90
.1666666666666
Changing to percent form
16.6666666666666666666666%
16 2/3 %
