Answer: 3
Step-by-step explanation: math
Sorry, I only know 8, 9, and 10.
8. This can be anything, but my guess would be 40 - 20 = 20
9. 3, because 3 x 3 = 9.
10. 7, because 7 x 4 = 28.
Hope this helped!
Answer:
1000 m³
Step-by-step explanation:
The base of a cube is just a square.
The area of a square is
, where l is the length.
Since we know the area of the base (the square) we can find l easily.

Now that we know the length of the sides, we have to take note that a cube has side lengths that are all congruent.
This means the height of the cube is also 10m.
Since the volume of a cube is represented as
, where l is the length, we can substitute 10 in as
to find it's total volume.

So the volume of this cube is 1000 m³.

Answer:
0.25
Step-by-step explanation:
The total number of marbles is 2 + 2 + 3+ 5 = 12
the number of green ones is 3
So the probability of green = 3/12 = 1/4 = 0.25
Answer:
$120
Step-by-step explanation:
Let the initial value of bond be $X
The future value of any bond is calculated by formula
FV= PV(1+r)^n
where
- FV is future value of bond
- PV is present value of bond
- r is the rate that at which value of bond appreciate
- n is the number of years of maturity
In the problem given
FV= $146
r = 4% = 0.04 (dividing 4 by 100 we get 0.04)
n = 5
substituting these value in formula

PV =$X = $120
Hence current value of bond is $120.
