Answer:
-81
Step-by-step explanation:
-6(2x² + 5x) - 9
substitute -4 for 'x'
-6[2(-4)² + 5(-4)] - 9
-6[2(16) + (-20) - 9]
-6(32 - 20) - 9
-6(12) - 9
-72 - 9 = -81
Answer:
1/36
Step-by-step explanation:
The probability that the first winner lives in Gaston is 2/9. The probability that the second winner lives in Gaston is 1/8, the number of remaining Gastonites divided by the total number remaining in the pool.
Then the probability of both of these events is the product:
P(2 from Gaston) = (2/9)(1/8) = 2/72 = 1/36
The probability both are from Gaston is 1/36.
Answer:
C)78.5
Step-by-step explanation:
∠BOZ = X
∠WOB = 7X - 4
X + 7X -4 = 180 {STRAIGHT LINE }
8X = 180 + 4
8X = 184
X = 184/8
X = 23
∠WOB = 7X - 4 = 7*23 - 4 = 161 - 4 = 157
OA bisects ∠WOB. So, ∠WOA =∠AOB
∠AOB = 1/2 of ∠WOB = 157/2 = 78.5
Answer:
One bottle of soap will hold 3/8
Step-by-step explanation:
3/4= The amount of soap she has in total
3/4= 6/8 which is the same amount but now we can divide it by 2
.75 (6/8) divided by 2= .375 (3/8)
So each soap dispenser will have 3.75 liters of soap.
Sentences: To check our work
.375x2= .75
3/4 divided by 2= 3.75
