Because the number is even, then the number of possible combinations will be: 110/2 = 55 let's consider a simpler example, the number: 10, then we have: 10+0, 9+1, 8+2, 7+3, 6+4, which is equal to 10/2 =5 combinations. Note: We are not considering permutations between the elements of the sum therefore 10+0, 0+10 counts as one combination.
Answer:
the blue whale weighs 143.5 more tons than an African elephant
Step-by-step explanation:
an adult blue whale is 300,000 pounds, an adult African elephant is 13,000 pounds
300,000 pounds = 150 tons
13,000 pounds = 6.5 tons
150-6.5= 143.5 tons
Given:
The group of 50 mice.
Event A = A male mouse is being chosen at random.
Event B = A mouse that is at least 6 months old being chosen.
The expression that describes a female mouse younger than 6 months old being chosen:
[A-} * [B] = inverse of A * B
Answer: PQR=32
Step-by-step explanation:
RQS+PQR=PQS
(4x+4)+(3x-1)=80
7x+3=80
7x=77
x=11
PQR=(3x-1)=> (3(11)-1) => 33-1=32
Answer:
y = -x + 9
Step-by-step explanation:
Since the line is parallel, the slope is -1.
y = -x + c
Substituting (0,9) into the above equation:
9 = 0 + c
c = 9
y = -x + 9
