Step-by-step explanation:
this will factor out to
X^2+6x+9
Answer:
x^2 + 6x + 9
Step-by-step explanation:
This is asking for (x+3) (x+3)
Using the FOIL method
(x * x) First, x times x
+ 3x Outside, x times 3
+ 3x Inside, x times 3
+ 9 Last, 3 times 3
Therefore, we have
(x*x) + 3x + 3x + 9
And simplified
x^2 + 6x + 9

What is a double-number line?In a double number line diagram, equivalent ratios are represented by two parallel number lines.
Given that, the hen takes 25 hours to produce 1 egg.
1 egg = 25 hours
3 eggs = 25 × 3 hours
3 eggs = 75 hours
Similarly,
100 eggs = 2500 hours
and,
12 eggs = 300 hours
Hence, the completed table is:
Eggs Time (hours)
3 75
100 2500

If 6×2 + 6y2 = 13xy, what is the ratio of x to y?
Answer:
Since 6X2 + 6Y2 = 13 xy
-- 6X2 / XY + 6Y2/XY =13
---> 6 X/Y + 6 Y/X =13
6a + 6/a =13
---> 6a2 + 6 =13a
---> 6a2 -13a +6 =0
---> 6a2 -9a - 4a +6 =0
---> (2a-3) (3a-2) =0
2a-3 = 0
a= 3/2
So the Ratio will be = 3:2

The function values of [tex]{q(2)}[/tex] is [tex]\bold{\dfrac{11}{4}}[/tex], [tex]q(0)[/tex] is UNDEFINED and [tex]q(-x)[/tex] is [tex]\bold{2+\dfrac{3}{x^2}}[/tex]
Step-by-step explanation:

I. The airport branch of a car rental company maintains a fleet of 50 SUVs. The interarrival time between requests for an SUV is 2.4 hours, on average, with a standard deviation of 2.4 hours. There is no indication of a systematic arrival patterns over the course of a day. Assume that, if all SUVs are rented, customers are willing to wait until there is an SUV available. An SUV is rented, on average, for 3 days, with a standard deviation of 1 day. a) What is the average number of SUVs parked in the company's lot
Answer:
20
Step-by-step explanation:
For the computation of the average number of SUVs parked in the company's lot first it is required to compute the utilization which is shown below:-
[tex]Utilization = \frac{p}{a\times m}[/tex]
where p indicates activity time which is equal to 3 days = 72 hours
a indicates an interarrival time which is equal to 2.4
m indicates the number of servers which is equal to 50
now we will put the values into the above formula
[tex]Utilization = \frac{72}{2.4\times 50}[/tex]
After solving the above equation we will get
u = 0.6
or
60%
now, the average cars parked in the company's lot is
[tex]Average\ cars = 50 - 60\%\times 50[/tex]
= 50 - 30
= 20

Lillian earned $397.50 at her job when she worked for 25 hours. What was her hourly wage, in dollars per hour? On the double number line below, fill in the given values, then use multiplication or division to find the missing value.
Answer:
$15.9
Step-by-step explanation:
$397.5 = 25 hour
=> x dollars = 1 hour
=> 397.5 * 1 = 25 * x
=> 397.5 = 25x
=> 397.5/25 = 25x/25
=> 15.9 = x
So, for 1 hour he earns $15.9
What does x equal in this equation x= .49x^2
Answer:
x=0, 2.04 (2dp)
Step-by-step explanation:
Assuming is it 0.49, our equation currently looks like this:
x = 0.49x^2
The first step is to move all x terms to one side which we can se by subtracting an x from both sides.
x - x=0.49x^2 - x
0 = 0.49x^2 - x
Now we can factorize by pulling out the x, which is a common factor:
0=x(0.49x-1)
We can now see that one of the solutions is x = 0, because anything in the brackets multiplied by 0 is 0.
To find the other solution we can divide both sides by x and solve:
0/x=x(0.49x - 1)/x
0=0.49x-1
1=0.49x
Now we just divide both sides by 0.49 to get our second answer!
1/0.49=0.49x/0.49
2.04=x
x = 0, 2.04 (2dp)
Hope this helped!
Are these ratios equivalent?
3 medium cars to 1 small car
18 medium cars to 6 small cars
Answer:
Yes
Step-by-step explanation:
3 medium cars to 1 small car can be made into a fraction like this: [tex]\frac{3}{1}[/tex] or [tex]\frac{1}{3}[/tex]. But you must be consistent if the denominator represents medium cars or small cars.
For this, I'm just going to make medium cars the numerator.
18 medium cars to 6 cars can be made into a fraction like this : [tex]\frac{18}{6}[/tex].
When you divide both fractions in a calculator (or in your head), you will realize that they both are the same value (equivalent).
[tex]\frac{3}{1}=\frac{18}{6} = 3[/tex]
[tex]\frac{1}{3} = \frac{6}{18} = .3333333[/tex]
These ratios are equivalent.
