Ravi says,” if 10 years are added to my age, then my age becomes 25.”if Ravi’s present age is x years,
then find the linear equation satisfying the given condition.
Answers
Answer:
The linear equation satisfying the given condition is,
\(x=t+15\)
where x is Ravi's age and t is the number of years
(after 10 years (t=10) his age becomes 25)
Step-by-step explanation:
Let x be Ravi's age
Now, his current age is unknown, but if you add 10 to it, then it becomes 25, so
x + 10 =25
so, his current age is x = 25 =10
x = 15
Now, we find the linear equation satisfying the given condition,
Let t be the number of years that have passed since the present time
so, if 0 years have passed, his age will be 15 years
after 1 year, his age will be 16 years
after 10 years, his age will be 25 years and so on
so
\(x = t + 15\)
this satisfies the given condition, since if we add ten years i.e t = 10,
then we get 25
The equation is:
⇨ x + 10 = 25Work/explanation:
Here's the linear equation for Ravi's age.
Ravi's age is x.
If you add 10 to x you get x + 10.
That gives 25.
So the linear equation is x + 10 = 25.

%
Answers
The person whose fruit salad will taste more melony is Genesis. The Option B is correct.
How can we calculate the percentage?A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.
We need to compute the melon percentage to determine whose fruit salad will taste more melony:
1. Ownen mixes 14 cups of melon and 3 cups of apple. The percentage for melon will be:
= 14/(3+14) × 100
= 82.3529411765
= 82.35%
2. Genesis mixes 6 cups of melon and 1 cups of apple. The percentage for melon will be:
= 6/7 × 100
= 85.7142857143
= 85.71%

Find x and y in terms of a and b.
Sax + by = 0
x + y = 2
(x, y) =
(a + b)
Answers
From the second equation, we have y = 2 - x.
Substituting this into the first equation, we get:
Sax + b(2 - x) = 0
Expanding this equation, we get:
Sax + 2b - bx = 0
Rearranging the terms, we get:
x(Sa - b) = 2b
Dividing both sides by (Sa - b), we get:
x = 2b/(Sa - b)
Substituting this value of x into the second equation, we get:
2b/(Sa - b) + y = 2
Substituting y = 2 - x, we get:
2b/(Sa - b) + (2 - 2b/(Sa - b)) = 2
Simplifying this equation, we get:
4b/(Sa - b) = 2
Multiplying both sides by (Sa - b)/2, we get:
2b = (Sa - b)
Simplifying this equation, we get:
b = a/2
Substituting this value of b into the equation for x, we get:
x = 2b/(Sa - b) = 2(a/2)/(Sa - a/2) = a/(2S - 1)
Substituting these values of x and y into the given point (x, y) = (a + b), we get:
(a/(2S - 1), 2 - a/(2S - 1)) = (a + a/2, a/2)
Therefore, the solution is:
x = a/(2S - 1) and y = 2 - a/(2S - 1).

The values of x and y in the given triangle are 41.4° and 114.5°
We have to values of x and y by using law of cosine
Using the Law of Cosines, we can find the values of x and y:
For angle x⁰:
cos(x⁰) = (a² + c² - b²) / (2ac)
cos(x⁰) = (15² + 18² - 12²) / (540)
cos(x⁰) = 0.75
x⁰ = cos⁻¹(0.75)
x⁰ = 41.4°
For angle y:
cos(A) = (b² + c² - a²) / (2bc)
cos(A) = (12² + 15² - 18²) / (360)
cos(A) = -0.4
A = cos⁻¹(-0.4)
y=114.5°

Answers
Intersection of B'∩C = {k, y}
To find the intersection of B' and C, we need to first find the complement of set B (B') and then find the intersection between B' and C.
1. Complement of set B (B'):
The complement of set B (B') consists of all elements in the universal set U that are not in set B. From the given information, set B is defined as {k, s, y}', which means it contains all elements in U except for k, s, and y. Therefore, the complement of set B is {f, m, x, z}.
2. Intersection between B' and C:
Now, we need to find the intersection between B' (complement of B) and set C. From the given information, set C is defined as {s, z}. To find the intersection, we need to identify the common elements between B' and C.
The elements present in both B' and C are k and y. Therefore, the intersection of B' and C is {k, y}.
So, the answer to (b) is B'∩C = {k, y}.

Answer:
y = 3/5x + 17/5
Step-by-step explanation:
m = 3/5
b = 17/5
Answer: Look below :D
Step-by-step explanation:
Since a slope perpendicular to another slope will mean that it is the negative reciprocal:
-5/3's negative reciprocal = 3/5.
Now we have completed 2 of 3 factors:
y = 3/5x + b
Now, with the given point, we plug in what we have:
y = 3/5x + b --> 1 = (3/5 * -4) + b
1 = -12/5 + b (let's convert everything to over 5)
5/5 = -12/5 + b
5/5 + 12/5 = b
17/5 = b
b = 17/5
The reason why I didn't do b/5 is because that would actually change the value of the equation.
Let's check:
y = 3/5x + 17/5 (Plug in the coordinates)
1 = (3/5)(-4) + 17/5
1 = -12/5 + 17/5
1 = 5/5
1 = 1

Answers
Answer:
The answer is 49
Step-by-step explanation:
We can use proportions to estimate the number of dogs in the entire population that have the disease, based on the sample of dogs with the disease.
We know that 42 dogs were selected for the study, and 14 of them had the disease. This means that the proportion of dogs in the sample with the disease is:
14/42 = 0.3333
We can use this proportion to estimate the number of dogs in the entire population that have the disease, by multiplying it by the total number of dogs:
0.3333 * 147 = 49
Therefore, the best estimate for the number of dogs that suffer from the disease is 49.
The ratio of the lengths of the sides of â–³ABC is 3:4:6. The perimeter of the triangle whose vertices are the midpoints of the sides of â–³ABC is 13 cm. What are the lengths of the sides of â–³ABC?
Answers
The length of the sides of triangle ABC are: 6, 8, and 12.
One of the conditions that two triangles are similar is their Three pairs of corresponding sides are proportional.
In the given problem, the ratio of the sides of triangle ABC is 3 : 4 : 6
Another triangle, let's say triangle DEF, is made with its vertices at midpoints of the sides of triangle ABC.
Hence, all three pairs of corresponding sides have the same proportion.
AB/DE = BC/EF = AC/DF = 1/2
Due to similarity, the ratio of the sides of triangle DEF is also 3 : 4 : 6.
ratio f sides : perimeter = 3 : 4 : 6 : 13
Since its perimeter is 13, it means that the length of sides of triangle DEF are: 3, 4, and 6
