Answer:
m = - 3
Step-by-step explanation:
a³ + 27 ← is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²), thus
a³ + 27
= a³ + 3³
= (a + 3)(a² - 3a + 9)
comparing a² - 3a + 9 to a² + ma + 9, then
m = - 3
Answer:
c. 309
Step-by-step explanation:
Hello
to solve the problem we will use a rule of three
Step 1
82.5% ⇒ 254 emp
100% ⇒ xemp
x represents number of employees so it must be a positive integer
x=309
step 2
prove 1
x*(82.25/100)=308*(82.25/100)
82.25 % of x = 254.1525
x=254, ok
note:
It is rounded to 254 because the percentage given in the exercise is not accurate, it should be 82.20064725%
Have a great day.
<span>Logarithm form is another way to express a number in exponential (exp.) form. log 8 (2) is the same as 8 (x) = 2 or in words, eight with exp. x equals two. If we take that equation and cube both sides, or raise each side to the power of 3, [8 (x)] with exp. 3 = 2 with exp. 3. This simplifies to 8 (3x) = 8. By definition, 8 is the same as 8 with exp. 1. So the equation is now 8 (3x) = 8 (1). This means 3x = 1. We can simplify to x = 1/3.</span>
Answer:
19 chicken wings
Step-by-step explanation:
For $39.10=23 chicken wings
For $1=23/39.10 chicken wings
