Answer:
Rs 1,650
Step-by-step explanation:
The given contribution are;
A contributes Rs 20,000, and B contributes Rs 30,000
The percentage of the profit A receives as manager = 25%
The amount of the profit divided in the ratio of their contribution = The remaining profit (75%)
The amount B gets = Rs1,350
The amount A gets = required
The ratio of their contribution at which the remaining profit is shared = 20,000:30,000 = 2:3
Where, out of 5 parts of 75% of the profits, B gets 3, while A gets 2
Let P represent the profit, we have;
B's share = 3/5× 0.75 × P = 1,350
∴ P = (5 × 1,350/3)/0.75 = 3,000
A gets 25% of the profits and 2/5 of the 75% remaining profit
∴ The amount A gets = 0.25×3000 + (2/5)×0.75×3000 = 1,650
Or simply put;
A gets the remainder of the profit which is Rs 3,000 - Rs 1,350 = Rs 1,650

Afreen says, "I am thinking of 3 consecutive numbers. The first is a multiple of 4, the second is a multiple of 5 and the third is a multiple of 6." What could the numbers be? Can you find 3 possible sets of numbers?
Answer:
The 3 ses that we found are:
{4, 5, 6}
{64, 65, 66}
{124, 125, 126}
Step-by-step explanation:
3 consecutive numbers are written as:
n, (n + 1), (n + 2)
We know that the first one is a multiple of 4.
Then n is a multiple of 4:
n = k*4
where k is an integer.
The second one is a multiple of 5, then:
(n + 1) = j*5
where j is an integer.
The last one is a multiple of 6.
(n + 2) = p*6
where p is an integer.
We want to find 3 sets.
The first one is trivial:
n = 4
n + 1 = 5
n + 2 = 6
4 is a multiple of 4
5 is a multiple of 5
6 is a multiple of 6.
Now let's find a set that is not trivial.
First, remember that all the multiples of 5 end with a 0 or a 5,
Then we can look for a value n, that is multiple of 4, and that has a last units digit equal to 4 (then the next one will have a units digit and will be multiple of 5)
For example, 4*6 = 24
24 is a multiple of 4.
The next number is 24 + 1 = 25, which is multiple of 5.
The next number is 25 + 1 = 26, which is not multiple of 6.
So let's try again.
4*11 = 44, is a multiple of 4.
The next number is 44 + 1 = 45
45 is a multiple of 5.
The next number is 45 + 1 = 46, which is not multiple of 6
So we need to try with another set.
4*16 = 64, is a multiple of 4.
The next number is 64 + 1 = 65, which is multiple of 5.
The next number is 66, which is multiple of 6:
6*11 = 66
Then the set:
n = 64
n + 1 = 65
n + 2 = 66
Is a possible set.
Now we can keep trying this, we can see that the next set has the numbers:
n = 4*31 = 124 is a multiple of 4.
The next number, is 124 + 1 = 125, which is a multiple of 5.
The next number is 125 + 1 = 126, which is multiple of 6
6*21 = 126
Then the set:
n = 124
n + 1 = 125
n + 2 = 126
Is another possible set.
The 3 ses that we found are:
{4, 5, 6}
{64, 65, 66}
{124, 125, 126}
Measure the length of AC. Use coordinate algebra to locate a point E on AC such that the ratio of AE to EC is equal to the ratio of AD to DB. Show how you derived your answer. (Hint: Let x and AC − x represent the two line segments that make up AC .)
If AC is 13 unit, then AC = 4.875 (5.875, 1) then the ratio of the segment via which E divides line AC is said to be equal to the ratio of AD and DB.
What is the line segment about?In the image attached, The length of AC = 13.
Take length of AE = x.
Take length of EC = 13 x.
The ratio of AE to EC = 0.6.
The [tex]\frac{AC}{EC}[/tex]
x = 0.6(13 - x)
x = 7.8 - 0.6x
1.6x = 7.8
x = 4.875
Therefore, AC = 4.875
Since E is found on AC so EC = 13 -x = 13 - 4.875 = 8.125
Therefore,
AC = 4.875
EC = 8.125

Answer:
O
Step-by-step explanation:
We can answer this by using the process of elimination
We want to find the position of 0.5
So let's begin
Looking at the number line...
D and E are both in between negative numbers
0.5 is not a negative number so immediately we can eliminate D and E
So it is between O and M
O is between 0 and 1
.5 is between 0 and 1 so O might be the answer
However let's look at M just to be safe.
M is located between 3 and 4.
Both 3 and 4 are greater than .5 meaning that M cannot represent .5
So we can conclude that O is the best answer

Question 2.
If 0 is an angle in the first quadrant, and cos(θ) = 0.669, determine the value of
cos(π - θ), cos(π + θ), and cos(4π - θ) using Symmetry.
Answer:
1) -0.669
2) -0.669
3) 0.669
Step-by-step explanation:
Since we are subtracting or adding multipled of pi, we will either obtain 0.669 or -0.669 as our answer for each of the three different questions.
Cosine is the x-coordinate in our orderes pairs. If our point ends up on the right side of the y-axis, the cosine will be positive. If our point ends up on left side, it will be negative.
Choose a thetha (I'm going to choose it in degrees) in the first quadrant to help with a visual.
If theta=70:
1) then 180-70=110 which is in second quadrant, so our cosines will be opposite in value.
2) then 180+70=250 which is in third quadrant, so our cosines will be opposite in value.
3) then 4×180-70=720-70=650 =1(360)+290 which ends up in the 4th quadrant which means the consines will have the same value.

Length of = ___units
Answer:
Step-by-step explanation:
This is a geometric means problem involving the height of 9. 9 is the geometric mean because it is the height of both ΔCFD and ΔEFD. Set up the problem accordingly:
[tex]\frac{5}{9}=\frac{9}{2x+3}[/tex] and cross multiply:
81 = 5(2x + 3) and
81 = 10x + 15 and
66 = 10x so
x = 6.6

identify each of the following as rational or irrational.
Answer:
Step-by-step explanation:
A rational number can be written as a fraction of two integers.
√23 is irrational because we do not know what the square root of 23 is in terms of integers in a fraction.
104.42 is rational because it can be expressed as 10442/100 . We can express it as this because
104.42 * 1 = 104.42 * 100/100 = 10442/100, and multiplying something by 1 keeps it the same
√64 is rational because it is equal to 8, and 8/1 is equal to 8
49.396 with the 6 repeating is rational because we can express 49.39 as
49.39 * 1 = 49.39 * 100/100 = 4939/100, and we are then left with
49.396- 49.39 = 0.006 (with the 6 repeating). A repeating decimal can be expressed as x/9, with the x representing all values before the repetition begins multiplied by 10.
For example, 0.6 with the 6 repeating can be represented as 6/9. This is because 0.6 * 10 = 6, and we divide that by 9. Similarly, 0.006 with the 6 repeating can be represented by 0.06/9
We add the two fractions together to get
4939/100 + 0.06/9
multiply both fractions by the other's denominator to even them out and make the numerator of the second fraction an integer
(4939*9)/(100*9) + (0.06*100)/(9*100)
= 44451/900 + 6/900
= 44460/900
Assuming that the last number has only the digits given, that is rational because, similarly to 104.42, it can be multiplied by a power of 10 to result in (integer)/(integer), making it rational. If the dots represent infinite digits, then it is not rational because there are infinite digits that are not repeating, and there is no way to know the last digit, so it is impossible to write a fraction from it
