To solve for the total number of 12 – flag signals Sally
can make, we need to make use of the formula:
total flags = d! / (a! b! c!)
Where,
d = is the number of flags to create a signal = 12
a = number of red flags = 5
b = number of green flags = 3
c = number of white flags = 4
We can observe from the equation that the individual
number of flags is factored out (or divided from) that is because all the 5 red
flags are similar, all the 3 flags are similar and all 4 flags are similar.
Going back into the equation, by substituting and
calculating:
total flags = 12! / (5! 3! 4!)
total flags = 27,720
<span>Therefore there are about 27,720 different 12-flags
signals.</span>
Rosie went to the mall to buy new shirts for school. The store she was shopping in had a sale in which all the shirts were $8 each as long as she also bought one pair of shorts for $6. If Rosie spent $38 how many shirts did she buy?
Answer:
$3.25
Step-by-step explanation:
Since there are three candle, you divide 9.75 by three.
Answer:
C
Step-by-step explanation:
Given
2x² - x - 6
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × - 6 = - 12 and sum = - 1
The factors are - 4 and + 3
Use these factors to split the x- term
2x² - 4x + 3x - 6 ( factor the first/second and third/fourth terms )
= 2x(x - 2) + 3(x - 2) ← factor out (x - 2) from each term
= (x - 2)(2x + 3) ← in factored form
Thus 2x + 3 is a factor → C
