Answer: 3/5
Step-by-step explanation:
Probabilty of blue tiles: 12/20 =3/5
Probability of letter b tiles: 10/20= 1/2
How to get the denominator?
4+6=10
2+8=10
10+10=20
Answer:
(2 z + 3) (4 z^2 - 6 z + 9)
Step-by-step explanation:
8z3 + 27
a = 2z
b = 3
a^2 = (2z)^2 = 2z^2
ab = (2z)*3 =6z
b^2 = 3^2 =9
a3 + b3 = (a + b)(a2 – ab + b2)
8z^2 +27 = (2z+3) (4z^2 -6z +9)
Answer:
Ani age is 21
Biju age is 18
Step-by-step explanation:
let Ani age be X
let Biju age be Y
the difference of their age is 3
i.e X - Y = 3......,....(equ. 1)
let Dharam age be A
let Cathy age be B
i.e A = 2x
B = y/2
the difference of their age is 30
Y/2 - 2x = 30..... (equ. 2)
from equ.1 X = ( 3+y).........( equ.3)
y/2 - 2(3+y) = 30
y/2 - 6 + 2y = 30
multiply both side by 2
y - 6 + 2y = 60
y + 2y = 60 - 6
3y = 54
Y = 18
from equ.3
X = 3+Y where y is 18
X = 3+18 = 21
No 10-2 =8 x=8
8+8 = 16 +2 = 18 if you add 5 units to the other side it would equal 15
18 and 15 are different numbers so no
Answer
You would need 250 of the smaller boxes to completely fill the larger one.
Step-by-step explanation:
50*30*20=30,000
10*3*4= 120
30,000/120= 250
