Answer:
160
Step-by-step explanation:
You could just multiply the whole number with the numerator and then divide the answer by the denominator. Or you could write the whole number over 1, and then simplify the numbers before multiplying straight across.
2/3 x 36
2/3 x 36/1
2/1 x 12/1 (simplified the 3 and the 36)
24/1=24 (just multiplied across)
Answer:
A, D, and F
Step-by-step explanation:
Tiara did multiply and regroup correctly in the first partial product. Tiara did not multiply and regroup correctly in the second partial product. Tiara was not correct when she added her 2 partial products.
Tiara should of got 18,291 but instead she got 16,291.
When she went to the part to multiply 3x4 she didn't add the remaining 2 from the 3x6+2. So if she did 3x4+2 she would of got the number 14 instead of 12 to put down in the second partial product. Which would make the addition part of it as 4,221 + 14070 = 8291 instead of 4,221 + 12,071 = 16, 291
I hope you understand :)
The ratio of their bases = 3√3 : 8
Step-by-step explanation:
Given,
The ratio of the volume of two cylinders is 27:64.
To find the ratio of the diameters of the cylinders of their base.
Formula
Let, the radius and height of a cylinder is r and h. The volume of the cylinder V = πr²h
Let,
Radius of cylinder 1 is R and the radius of the cylinder 2 is r.
The height of the both cylinder is h.
According to the problem,
πR²h= 27a and πr²h= 64a
So,
πR²h : πr²h = 27a:64a
or, R²:r² = 27:64
or, R:r = 3√3 : 8
Hence,
The ratio of their bases = 3√3 : 8
