Answer:
The density of oak is <u>0.695</u> grams per cubic centimeter.
Step-by-step explanation:
Given:
Oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters.
Now, to find the density of oak in grams per cubic centimeter.
Mass (m) = 2.85 kilograms.
So, using conversion factor we convert into grams:
Volume (v) = 4100 cubic centimeters.
Now, to get the density by using formula:
Therefore, the density of oak is 0.695 in grams per cubic centimeter.
3/4 mile is 0.75 mile per minute
There are 60 minutes in one hour
0.75 times 60 equals 45 miles
77/20 = 3.85 <== terminating decimal
Hello!
Let's subtract the eight DVDs Joe received as gifts, because he didn't buy them on his own.
35 - 8 = 27
Now, divide the remaining CDs by the 3 years he collected his DVDs in.
27 ÷ 3 = 9
A N S W E R:
Joe bought 9 DVDs last year.
Good day!
Combine like terms:
subtract x from both sides to get
2x+5=14
subtract 5
2x=9
isolate x:
divide 2 from both sides to isolate x
x=9/2
that's your final answer. unless your teacher wants you to put it in decimal form in which all you do is divide 9÷2.
