Answer:
1. 20
2. 0
Step-by-step explanation:
1. 20
11 -12÷4+3 (6-2)
Brackets first
11-12÷4+3 x 4
Then division and multiplication
11-3+12
Subtraction next
8+12
Now addition
8+12=20
2. Anything divided by 0 is 0
Answer:
B. 4/21
Step-by-step explanation:
⇒This question is on probability
⇒Number of boys=3
⇒Number of girls=4
⇒P(S)= 4+3=7
Probability for a girl to win is= 4/7
We have 3 awards a free movie ticket, a collectible poster, or a free popcorn
P(S)= 3
Probability of being awarded a free popcorn = 1/3
The probability that a girl will win free popcorn =
4/7 * 1/3 = 4/21
hope i helped and have a wonderful day
If you're asking for the final term, the solution is to take b(from ax^2+bx+c), half it, and then square it. So in this case, b is 8.
8/2=4
4^2=16
So:
v^2+8v+16
If you factor it, it becomes (v+4)^2, which shows that its a perfect square.
Answer:
Step-by-step explanation:
Let the number of small boxes = x
and the number of large boxes = y
Total number of boxes = 24
Therefore, equation will be,
x + y = 24 ------ (1)
Since, volume of the smaller boxes = 9 cubic feet
And the volume of larger boxes = 24 cubic feet
Therefore, total volume of the boxes = (9x + 24y)
Since combined volume of all boxes = 441 cubic feet
Therefore, equation will be,
9x + 24y = 441 ------ (2)
