Answer: 16
Step-by-step explanation:
The area of a rectangle can be found by multiplying its length and its height. You may consider the breadth as just another word for length.
A = L * W
Since we know what are area is, we may substitute it into the equation.
144 = L * W
We also know what our width (our breadth) is, so we will also substitute it in
144 = L * 9
To solve for our length, we divide both sides by 9 to isolate L
[tex]\frac{144}{9} = \frac{L * 9}{9}[/tex]
We see that the two 9's on the right hand side cancel out to give us L
[tex]\frac{144}{9} = 16[/tex]
So our L is equal to 16.
We can check our work by multiplying the length and breadth together again to see if they give 144 as a product, which they do.

How do I solve 1/3 = 5n/600
Answer:
n = 40
Step-by-step explanation:
A fraction can be equivlent to another fraction, right? so 1/3 = ?/600 - 3*200 = 600 and 1*200 = 200 so 5n/600 should be equal to 200/600 and since 5n = 200 we divide by 5 on both sides and get n = 40

The expression sin 57° is equal to
(1) tan 33°
(3) tan 57°
(2) cos 33°
(4) cos 57°
Answer:
[tex]cos(33^{\circ})[/tex]
Step-by-step explanation:
Given
[tex]sin(57^{\circ})[/tex]
Required
Determine an equivalent expression
In trigonometry:
[tex]sin(\theta)= cos(90^{\circ} - \theta)[/tex]
In [tex]sin(57^{\circ})[/tex]
[tex]\theta=57^{\circ}[/tex]
Substitute [tex]57^{\circ}[/tex] for [tex]\theta[/tex]
in [tex]sin(\theta)= cos(90^{\circ} - \theta)[/tex]
[tex]sin(57^{\circ})= cos(90^{\circ} - 57^{\circ})[/tex]
[tex]sin(57^{\circ})= cos(33^{\circ})[/tex]
Hence, the equivalent expression is: [tex]cos(33^{\circ})[/tex]

-x+5y=8 3x+7y=-3 find the equation
Answer:
The solution to the system of equations be:
[tex]x=-\frac{71}{22},\:y=\frac{21}{22}[/tex]
Step-by-step explanation:
Given the system of equation
[tex]\begin{bmatrix}-x+5y=8\\ 3x+7y=-3\end{bmatrix}[/tex]
Multiply -x+5y=8 by 3: -3x+15y=24
[tex]\begin{bmatrix}-3x+15y=24\\ 3x+7y=-3\end{bmatrix}[/tex]
Add the equations
[tex]3x+7y=-3[/tex]
[tex]+[/tex]
[tex]\underline{-3x+15y=24}[/tex]
[tex]22y=21[/tex]
solving 22y=21 for y
[tex]22y=21[/tex]
Divide both sides by 22
[tex]\frac{22y}{22}=\frac{21}{22}[/tex]
Simplify
[tex]y=\frac{21}{22}[/tex]
For -3x+15y=24 plug in y = 21/22
[tex]-3x+15\cdot \frac{21}{22}=24[/tex]
Subtract 15 · 21/22 from both sides
[tex]-3x+15\cdot \frac{21}{22}-15\cdot \frac{21}{22}=24-15\cdot \frac{21}{22}[/tex]
[tex]-3x=\frac{213}{22}[/tex]
Divide both sides by -3
[tex]\frac{-3x}{-3}=\frac{\frac{213}{22}}{-3}[/tex]
[tex]x=-\frac{71}{22}[/tex]
The solution to the system of equations be:
[tex]x=-\frac{71}{22},\:y=\frac{21}{22}[/tex]

Find the third term of a proportional if the first, second and fourth terms are 24, 36, 126
Answer:
The third term of a proportional is: 84
Step-by-step explanation:
We know that if a, b, c and d are in proportion, then:
a × d = b × c
In our case, we are given the first, second, and fourth terms are 24, 36, 126.
a = 24
b = 36
d = 126
and we have to determine the third term 'c'.
as we know that if a, b, c, and d are in proportion, then:
a × d = b × c
Thus,
substituting a = 24, b = 36, d = 126 to determine
24 × 126 = 36 × c
c = (24 × 126)/36
c = 3024/36
c = 84
Thus, the third term of a proportional is: 84

Answer: See the attached image below. I've filled in the table with the proper values.
Row 2: AFB = 36, BFC = 54, EFA = 144
Row 3: AFB = 40, BCF = 50, DFE = 40
=======================================================
Explanation:
angles AFB and BFC add to 90 degrees since they form a right angle.
In row 1, we see that 48+42 = 90
Angles AFB and DFE are congruent since they are vertical angles. For row 1, we have both of these angles equal to 48 degrees.
Also for row 1, we have angles BFC and CFD add to 42+90 = 132, which is exactly the measure of angle BFD. This angle is congruent to angle EFA because they are vertical angles. So that's how angle EFA is 132.
--------------------------
Now onto row 2
We'll use the ideas of row 1 to work our way backwards to fill in the missing items.
We're given DFE is 36 degrees. This must mean that AFB is also 36 degrees. These angles are vertical angles.
Then we'll use the idea that (angleAFB)+(angleBFC) = 90 to find that
angle BFC = 90 - (angle AFB) = 90 - 36 = 54
Lastly for this row, we can say,
angle BFD = (angle BFC) + (angle CFD) = 54 + 90 = 144
angle EFA = angle BFD = 144
To summarize the missing items of row 2, we have...
angle AFB = 36angle BFC = 54angle EFA = 144---------------------------
Now onto row 3. We use the same tricks (more or less) that were used on row 2.
If angle EFA is 140, then so is angle BFD. These are vertical angles.
(angle BFC) + (angle CFD) = angle BFD
(angle BFC) + 90 = 140
angle BFC = 140-90
angle BFC = 50
This in turn lets us say,
(angle AFB) + (angle BFC) = 90
angle AFB = 90 - (angle BFC)
angle AFB = 90 - 50
angle AFB = 40
angle DFE = angle AFB = 40
To summarize the missing pieces we found:
angle AFB = 40angle BFC = 50angle DFE = 40All of the values are filled in the table shown below.
A deck of 52 cards contains 12 picture cards. If the 52 cards are distributed in a random manner among four players in such a way that each player receives 13 cards, what is the probability that each player will receive three picture cards
Answer:
The probability that each player will receive three picture cards = 0.0324
Step-by-step explanation:
As given,
A deck of 52 cards contains 12 picture cards
Remaining card = 52 - 12 = 40
So,
Total number of ways in which 12 picture card is distributed = [tex]\frac{12!}{3! 3! 3! 3!}[/tex]
Now,
The Total number of ways in which Remaining cards are distributed = [tex]\frac{40!}{10! 10! 10! 10!}[/tex]
So,
Total number of ways of getting 3 picture card and remaining card = [tex]\frac{12!}{3! 3! 3! 3!}[/tex]× [tex]\frac{40!}{10! 10! 10! 10!}[/tex]
= [tex]\frac{12! 40!}{(3!)^{4} (10!)^{4} }[/tex]
Now,
Total number of ways to distribute 52 cards so that each people get 13 card = [tex]\frac{52!}{13! 13! 13! 13!} = \frac{52!}{ (13!)^{4} }[/tex]
∴ The probability = [tex]\frac{\frac{12! 40!}{(3!)^{4} (10!)^{4} }}{\frac{52!}{(13!)^{4} }}[/tex]
= [tex]\frac{12! 40!}{(3!)^{4} (10!)^{4} }[/tex]×[tex]\frac{(13!)^{4} }{ 52! }[/tex]
= [tex]\frac{12! 40!}{(3!)^{4} (10!)^{4} }[/tex]×[tex]\frac{(13.12.11.10!)^{4} }{ 52.51.50.49.48.47.46.45.44.43.42.41.40! }[/tex]
= [tex]\frac{12!}{(3!)^{4} }[/tex]×[tex]\frac{(13.12.11)^{4} }{ 52.51.50.49.48.47.46.45.44.43.42.41}[/tex]
= [tex]\frac{479,001,600}{(6)^{4} }[/tex]×[tex]\frac{(1716)^{4} }{ 52.51.50.49.48.47.46.45.44.43.42.41}[/tex]
= 0.0324
∴ we get
The probability that each player will receive three picture cards = 0.0324
