Alright, so we'd use the combinations with repetition formula, so we choose from 4 schools to distribute to and distribute 8 blackboards. It's then
( 8+4-1)!/8!(4-1)!=11!/(3!*8!)=165
For at least one blackboard, we first distribute 1 to each school and then have 4 blackboards left, getting (4+4-1)!/4!(4-1)!=7!/(4!*3!)=35
Answer:
x-coordinate = 0
Step-by-step explanation:
In a coordinate plan there are two perpendicular lines one is x-axis and another is y-axis
x-axis is a horizontal line and y-axis is a vertical line.
Both lines intersect each other at (0,0).
On x-axis, y-coordinate remains same , i.e., y=0.
On y-axis, x-coordinate remains same , i.e., x=0.
Therefore, the x co-ordinate of any point lying on the y axis is 0.
Answer:
1933
Step-by-step explanation:
9 x (1 + 345) - 6 - 8 + 48 x 23 - 77
Use BODMAS method to solve these type of equation
B - Brackets
O - Power
D - Division
M - Multiplication
A - Addition
S - Subtraction
_________________________________________________________
Brackets - 1 + 345 = 346
Multiplication
9 x 346 = 3114
48 x 23 = 1104
Lets rewrite the equation now
3114 - 6 + 1104 - 77
Addition
6 + 1104 = 1110
Subtraction
3114 - 1104 = 2010
2010 - 77 = 1933
Answer = 1933

55/8 or 55:8 will be the unit rate I think
