Surface Area of Cube = width^2 * 6 (sides of the cube)
Therefore, (3.5)^2 * 6 =
73.5 [whatever units]^2
Assuming the order does not matter, you want the number of combinations of 9 things taken 5 at a time. The combinations can be shown as C(9,5), 9C5.
C(9, 5) =
9/5(9-5) =
9*8*7*6*5 / 5*4
The 5 terms cancel.
9*8*7*6 / 4*3*2 =
9*7*2 =
126
The above change is because 4*2 cancels the 8 in the numerator and 6/3 = 2
Therefore, the solution is 126.
Answer:
240^2 - 120x
Step-by-step explanation:
4(2x - 1) x 3 x (2x 5)
4(2x - 1) x 3 x (10x)
4(2x - 1) x 3 x 10x
120x x (2x-1)
240^2 - 120x
Company C services 16 office suites.
Company A services 1/3 of the suites and Company B services 2/5; together they service 1/3+2/5. Find a common denominator; 15 is the smallest:
1/3=5/15
2/5=6/15
5/15+6/15 = 11/15
This means that 1-11/15 = 4/15 of the suites are serviced by Company C.
4/15 of 60 = 4/15(60) = 4/15(60/1) = 240/15 = 16
Answer:
False.
Step-by-step explanation:
Because 12 and 9 are both multiples of 3.
