Step-by-step explanation:
find the number of words with or without meaning , which can be made by using all the letters of word ganga
Answer:
There are total 5 letters , of which A occur two times and G occur 2 times
Therefore , The number of permutations starting with A is 4! i.e 24
Thus , 25th word will be start from G i.e GGAAN
By rearranging according to the dictionary , we get
The 26th word will be GGANA
Hence , the 26th word is GGANA
Answer:
30
Step-by-step explanation
total number of letters in the word, n = 5
out of which G and A repeats 2 times each
p1 = p2 = 2
according to the equation of number of permutations,
= [tex]\frac{n!}{p_{1}! p_{2}! }[/tex]
total number of words = 5!/ (2! x 2!)
= 30
You are a landscaper, and you are designing a fence to enclose part of a yard. The section to be enclosed is rectangular and has a width of 21 feet and a length of 38 feet. What length of fence, in feet, will you need to enclose this part of the yard? 59 60 118 120 798
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area
:
This illustrated on a graph where y axis is the area and x axis is the width:

gil borrows $8000 for college expenses. he will pay a total of $2280 back in interest after 6 years. what was his interest rate
Answer:
R = 41.8129%/year
Equation:
r = (1/t)(A/P - 1)
Calculation:
Solving our equation:
r = (1/6)((8000/2280) - 1) = 0.41812865
r = 0.41812865
Converting r decimal to R a percentage
R = 0.41812865 * 100 = 41.8129%/year
The interest rate required to get a total amount, principal plus interest, of $8,000.00 from simple interest on a principal of $2,280.00 over 6 years is 41.8129% per year.
Step-by-step explanation:
Answer:
I believe it is 4.75 %
Step-by-step explanation:
2,280 × 100 = 228,000
228,000 / 8,000 = 28.5
28.5/6 = 4.75 %

(-1,0) and (5,0)
Answer:
C
Step-by-step explanation:
The zeros are also known as x-intercepts so it is the points on the x axis.

What is the area of this polygon on a coordinate plane?
20 square units
9 square units
3 square units
14 square units
Answer:
i need a picture or something to solve this so...
Step-by-step explanation:
what is the sum of the interior angles of a heptagon ?
Let n be rhe number of vertices in the polygon, then the sum of all interior angle is (n - 2) × 180°.
Number of sides in a heptagon = 7
So, n = 7
So,
the sum of the interior angles of a heptagon
= (7 - 2) × 180°
= 5 × 180°
= 900°
Answer:
900
Step-by-step explanation:
Graph 8x−4y=16. From Big Ideas Math
Solve for y.
8x−4y=16
-4y = -8x + 16
y = (-8x + 16)/-4
y = (-8x)/-4 + (16/-4)
y = 2x - 4
We only need two points to graph linear equations.
Now let x be 0 and solve for y.
y = 2(0) - 4
y = -4
This leads to the point (0, -4).
We need another point.
Let y = 0 and solve for x.
0 = 2x - 4
4 = 2x
4/2 = x
2 = x
This leads to the point (2,0).
Plot these two points on the xy-plane and connect the points with a straight line.
I'll let you do that.
Understand?

Solve the system of equation. Write the solution as a coordinate point
Answer:
(2,16)
Step-by-step explanation:
y=-x+18
y=8x
8x=-x+18
8x+x=9x
-x+x=0
9x=18
9x/9=x
18/9=2
x=2
y=8(2)
y=16
Answer:
(2,16)
Step-by-step explanation:
Step 1: Substitute -x+18 for y in y=8x:
-x+18=8x Add X to both sides
9x=18 Divide 9 by both sides
x=2
y=8(2)Plug in the new value for x(which is 2) into one of the equations
y=16

What method can be used to prove the triangles below are congruent
Answer:
SSS?Step-by-step explanation:
I don't know why the answers don't offer this an option. However, the side that shares both triangles must be congruent to itself and the other highlighted congruent parts are sides, not angles. Therefore by my calculations, the answer has to be SSS, but this isn't a choice.

The difference of the squares of two positive consecutive even integers is 84. Find the integers.
Answer:
The two integers are 20 and 22.
Step-by-step explanation:
Let x be the first integer.
[tex](x+2)^{2}-x^{2} = 84\\x^{2} +4x+4-x^{2} = 84\\4x = 80\\x = 20[/tex]
Applying the difference of squares, and solving the equation, it is found that the numbers are 20 and 22.
----------------------
The two consecutive even integers are: n and n + 2.The difference of the squares is given by:[tex]D_s = (n+2)^2 - n^2[/tex]
Expanding the difference:
[tex]D_s = n^2 + 4n + 4 - n^2[/tex]
[tex]D_s = 4n + 4[/tex]
----------------------
The difference is 84, thus:
[tex]D_s = 84[/tex]
Now, we solve for n.
[tex]4n + 4 = 84[/tex]
[tex]4n = 80[/tex]
[tex]n = \frac{80}{4}[/tex]
[tex]n = 20[/tex]
----------------------
Thus, the numbers are: [tex]n = 20[/tex] and [tex]n + 2 = 20 + 2 = 22[/tex]

What is the correct factorization of:
x? - 11x + 18
9514 1404 393
Answer:
x² -11x +18 = (x -9)(x -2)
Step-by-step explanation:
The x-coefficient is the sum of the constants in the binomial factors; the constant term is their product. It usually works well to look for factors of the constant that have the right sum. Here, both must be negative.
18 = (-1)(-18) = (-2)(-9) = (-3)(-6)
The factors -2 and -9 have a sum of -11, so those are the binomial constants of interest. The factorization is ...
x² -11x +18 = (x -9)(x -2)

There are 12 applicants for financial aid. The Scholarship allows four students to receive the money. How many different ways can these scholarships be awarded? The first scholarship is $1000, the second is $750, the third is $500, and the last is $250. Only place a numeric value as an answer.
Answer:
495 ways
Step-by-step explanation:
Given that:
Total number of applicants (n) = 12
Required number (r) = 4
Using the combination formula :
nCr = n! / (n-r)!r!
12C4 = 12! / (12 - 4)!4!
12C4 = 12! / 8!4!
12C4 = (12*11*10*9) / 4*3*2*1
12C4 = 11880 / 24
= 495 ways
