The time it will a take them for both ricardo and his father to finish the painting if they work together is;
t = 2.4 hours
Time for ricardo to paint the set of kitchen cabinets = 6 hours
Time for Ricardo's father to finish painting = 4 hours
This means that ricardo in 1 hour paints 1/6 of the cabinets
His father in 1 hour paints 1/4 of the cabinets
If they work together, in one hour, they would have painted;
1/6 + 1/4 = 5/12 of the cabinet
If 5/12 of the cabinet is done in an hour,then 12/12 will be done in; ((12/12) × 1)/(5/12)
⇒ 1 × 12/5
⇒ 2.4 hours

The correct answer is: " 2 hours and 24 minutes ";
or; write as: " 2.4 hours " .
____
Step-by-step explanation:
[tex]\frac{x}{4} + \frac{x}{6} = 1[/tex] ; → { " 1 (one) whole job." }.
We want to solve for "x" ; the total time, in "hours", that will take them if they work together.
What is the LCD (least common denominator of "4" and "6" ?
→ Note that "4 * 6 = 24" ; so, "24" would work, but let's see if we can find the LCD —a number less then "24" ;
4: 2, 4, 12, 16, 20, 24,
6: 1, 2, 3, 6, 12
⇒ We see that "12" is the LCD.
_____
So, " [tex]\frac{x}{4} = \frac{?}{12}[/tex] " ; to solve for "?" ;
→ 4 * (what value?) = 12 ?
→ 12 ÷ 4 = (that value) ; ⇒ = " 3 " .
_____
So: [tex]\frac{x}{4} = \frac{(x*3)}{(4*3)} = \frac{3x}{12}[/tex] ;
_____
Now: " [tex]\frac{x}{6} = \frac{?}{12}[/tex] " ; to solve for "?" ;
→ 6 * (what value?) = 12 ?
→ 12 ÷ 6 = (that value) ; ⇒ = " 2 " .
_____
So: " [tex]\frac{x}{6} = \frac{(x*2)}{(6*2)} = \frac{2x}{12}[/tex] ;
Now: → [tex]\frac{x}{4} + \frac{x}{6} = 1[/tex] ;
Substitute our converted values:
→ [tex]\frac{3x}{12} + \frac{2x}{12}=1[/tex] ;
Then simplify the "left-hand side" of the equation:
_____
→ [tex]\frac{3x}{12} + \frac{2x}{12} = \frac{(3x+2x)}{12}[/tex] = [tex]\frac{5x}{12}[/tex] ;
Now, rewrite the simplified equation; and bring down the "1" :
_____
→ [tex]\frac{5x}{12} = 1[/tex] ;
Now, solve for "x" ; as follows:
_____
⇒ 5x = ( 1 * 12 ) ;
→ 5x = 12 ;
Now, divide Each Side of the equation by "5" ;
to isolate "x" on one side of the equation; & to solve for "x" (in hours):
_____
→ 5x / 5 = 12 / 5 ;
_____
to get: x = (12/5) hours.
_____
Now: We have (12/5) of 1 hour ; 24/10
Note the exact conversion: " 60 min. = 1 hr." :
So, 12/5 of 60 minutes;
= " [tex]\frac{12}{5}[/tex] * [tex]}\frac{60}{1}[/tex] " (minutes) ;
____
The "5" cancels to a "1" ; and the "60" cancels to a "12" :
{since: "60 ÷ 5 = 12" ; & since: "5 ÷ 5 = 1 " .}.
→ And we can rewrite as:
" [tex]\frac{12}{1} * \frac{12}{1}[/tex] " (minutes) = "12 * 12" minutes = 144 minutes.
⇒ " 144 minutes" equals: How many hours? " 144 ÷ 60 = 2.4 hours " ;
or; more specifically:
⇒ We have "2 hours and _(some) minutes".
→ that is; " 2 hours plus 0.4 hour(s) " .
⇒ [tex]\frac{(0.4) hr}{1}*\frac{(60)min}{1 hr} = [(0.4)*(60)] minutes[/tex] ;
= 24 minutes.
____
Alternate method:
____
(12/5 hours) = (12 ÷ 5) hours = " 2.4 hours " ; (and continue if desired).
____
So: The correct answer is: " 2 hours and 24 minutes ";
or; write as: " 2.4 hours " .

.0015
.16
Answer
The awnser is .0235
The probability that a randomly selected day the flight will depart after 9:11 am is 0.0235. The Option B is correct.
What is the likelihood of flights departing after 9:11 am?The probability of a randomly selected day's flight departing after 9:11 am are determined by analyzing historical flight data. By examining the past departure times, we calculate the proportion of flights that departed after 9:11 am to the total number of flights.
This gives us the probability of a flight departing after that time on any given day. This probability will give us an idea of how often flights tend to depart later in the day. Therefore, the Option B is correct.

Original: $110
New: $59
%Decrease:__________
Answer:
46.36%
Step-by-step explanation:
Original: 110
New: 59
Percent Decrease: x
110 - 59 = 51
51/110 ≈ 46.3636... ≈ 46.36%
-Chetan K
Answer:
46.36% or 46% (rounded)
Step-by-step explanation:
110-59=51
Question now: What percent of 110 is 51
Step 1: We make the assumption that 110 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
tep 3: From step 1, it follows that 100%= 110.
Step 4: In the same vein, x%=51.
Step 5: This gives us a pair of simple equations:
100% = 110(1)
x%=51(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x%=110/51
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100%=51/110
⇒=46.36%

7=3 over 4x what is x?
Answer:
x=28/3
Step-by-step explanation:
combine multiplied terms into a single fraction
7 = 3x/4
multiply all terms by the same value to eliminate fraction denominators
4 · 7 = 4 · 3x/4
cancel multiplied terms that are in the denominator
4 · 7 = 3x
multiply the numbers
28 = 3x
divide both sides of the equation by the same term
28/3 = 3x/3
simplify
a. cancel that are in numerator and denominator
28/3 = x
b. move the variable to the left
x = 28/3

Answer:
81
Step-by-step explanation:
Here, some steps to evaluate (-9)².
Step 1 :- A negative base raised to an even powers equal positive.
9 ²Step 2 :- Write exponentiation as multiplicaton.
9 × 9Step 3 :- Multiply it .

So, after multiplying we get 81.
Convert each fraction to its equivalent using the least common denominator.
1/3 1/4
I am, honestly, slightly confused by the question wording, so here is what I think you need! :D
We can start by listing multiplies for each:
3:
3, 6, 9, 12, 15, 18, etc
4:
4, 8, 12, 16, 20, 24, etct
We can see that the least common denominator will be 12.
Answer:
[tex]\frac{1}{3}=\frac{x}{12}=\frac{4}{12}[/tex]
[tex]\frac{1}{4} =\frac{x}{12} =\frac{3}{12}[/tex]
If you need to multiply them:
[tex]\frac{4}{12} *\frac{3}{12} = \frac{12}{144} = \frac{1}{12}[/tex]
But you do not need to use a least common denominator for multiplying and can go straight to this:
[tex]\frac{1}{3} *\frac{1}{4} =\frac{1}{12}[/tex]
Hope this helps, have a nice day!

1. Match the polynomial with its end behavior.
A. f(x) = -2x + 3
B. f(x) = x2 - 6x + 3
1. As x gets larger and larger in either
the positive or negative direction,
f(x) gets larger and larger in the
positive direction.
C. f(x) = 1 – x2 + 2x3
D.f(x) = 7 - x4
DE
2. As x gets larger and larger in the
positive direction, f(x) gets larger
and larger in the positive direction.
As x gets larger and larger in the
negative direction, f(x) gets larger
and larger in the negative direction.
3. As x gets larger and larger in the
positive direction, f(x) gets larger
and larger in the negative (help please)direction.
As x gets larger and larger in the
negative direction, f(x) gets larger
and larger in the positive direction.
4. As x gets larger and larger in either
the positive or negative direction,
f(x) gets larger and larger in the
negative direction.
Using limit concepts, the matching pairs are:
A - 3
B - 1
C - 2
D - 4
The end behavior of a function f(x) is given by it's limit as x goes to infinity.
Function A:
[tex]f(x) = -2x + 3[/tex], then:
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} -2x = -2(-\infty) = \infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) \lim_{x \rightarrow -\infty} -2x = -2(\infty) = -\infty[/tex]
Thus, inverse directions, so matching pair with 3.
Function B:
[tex]f(x) = x^2 - 6x + 3[/tex], then:
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} x^2 = (-\infty)^2 = \infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) \lim_{x \rightarrow -\infty} x^2 = (\infty)^2 = \infty[/tex]
Always positive, so matching pair with 1.
Function C:
[tex]f(x) = 1 - x^2 + 2x^3[/tex], then:
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} 2x^3 = 2(-\infty)^3 = -\infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) \lim_{x \rightarrow -\infty} 2x^3 = 2(\infty)^3 = \infty[/tex]
Same directions, thus, matching pair with 2.
Function D:
[tex]f(x) = 7 - x^4[/tex], then:
[tex]\lim_{x \rightarrow -\infty} f(x) = \lim_{x \rightarrow -\infty} -x^4 = -(-\infty)^4 = -\infty[/tex]
[tex]\lim_{x \rightarrow \infty} f(x) \lim_{x \rightarrow -\infty} -x^4 = -(\infty)^4 = -\infty[/tex]
Always negative, so matching pair with 4.
