She used 54 inches. 3/4 is equal to .75 so you can find 3/4 of the board by taking the fool length and multiplying it by .75 so 6•.75=4.5. So 3/4 of the board is 4.5 ft. However, the answer has to be in inches so since there are 12 inches in a foot you multiply 4.5•12 and that gives you your answer:54 inches.
Answer:
volume = 1809 cm³
Step-by-step explanation:
The ratio of the height of two similar cylinder is 1:3 . The volume of the smaller cylinder is 67 cm³. The volume of the larger cylinder can be computed below:
If 2 object are similar and the ratio of the corresponding sides is x ,then the ratio of their volume is x³.
ratio of height = 1/3
ratio of volume = (1/3)³ = 1/27
volume of smaller cylinder/volume of larger cylinder = 1/27 = 67/x
where
x = volume of the larger cylinder
x = 27 × 67
x = 1809 cm³
volume = 1809 cm³
You will have 40% of your savings left after buying brushes and paint. The fraction is 4/10, which you can simplify to 2/5.
<h3>Given:</h3>
▪ 
First, rewrite the numerator in such a way that the coefficient 2.1 becomes 21:
Divide the coefficient:
Divide the base by subtracting the exponents of the base 10.
Hence, the quotient of the given expression has a coefficient of 3 and the exponent of the base 10 is -4.
Answer:
See below
Step-by-step explanation:
Which is the closest to 6
or 
So, find the square root of each ( I suggest using a calculator)
Which is closest? Let's see.
6 - 5.83 = 0.17
6.24 - 6 = 0.24
6 - 5.91 = 0.09
6.16 - 6 = 0.16
Find the smallest #
0.09 is the smallest, so 5.91 is the closest. Square the #, we get 
Hope this helps! =D
