Answer:
Step-by-step explanation:
Please type numerals and punctuation for your mixed numbers.
I will have to assume that you meant 2 5/6 and 1 1/3, and that you are subtracting 2 5/6 from - 1 1/3. If that is correct, then we determine the LCD and rewrite -1 1/3 using this LCD:
-1 1/3 -1 2/6
-2 5/6 -2 5/6
----------
-3 7/6 or -4 1/6
The best calculation of this difference is -4 1/6 and the best estimate is
-1 - 3, or -4
Answer:
Step-by-step explanation:
Area of a circle is pi r squared.
So 3.142 times the radius squared.
They gave you the diameter(d), that's the distance all the way across. You need the radius(r), which is one half of the diameter. 7 divided by 2.
3.142X3.5squared=
Well, 3.5 squared is 3.5X3.5=12.25
So, then 3.142X12.25=38.4895
Now, we round. Second decimal place is an eight, followed by a nine. Five or above means round up.
38.49
Answer:
-2/5 would be 2 down and 5 right
Half
you write half in the blank
Answer:
The estimate is less than the actual length of the CD.
Step-by-step explanation:
Consider the provided information.
Maurice's new CD has 12 songs. Each song lasts between 3 and 4 minutes.
That means the minimum length of the CD should be: 12×3=36 minutes.
The maximum length of the CD should be: 12×4=48 minutes
He estimates that the whole CD is about 30 minutes long.
30 minutes is less than 36 minutes.
That means, the estimate is less than the actual length of the CD.
Hence, the correct statement is: The estimate is less than the actual length of the CD.
