The age of Sita is five years more than Gautam's age. 5 years ago, the ratio of their ages was 3:2. Find their present ages.
Solution:-The age of Sita = (x + 5) years.
And, the age of Gautam = x years.
Now,
5 years ago, the ratio of their ages was 3 : 2
[tex] \therefore [/tex] [tex] \bf \frac{3}{2} \: = \frac{x \: + \: 5}{x} [/tex]
Now by cross multiplying, we get,
3x = 2(x + 5)
3x = 2x + 10
3x - 2x = 10
x = 10Hence, the age of Sita = (x + 5) = (10 + 5) = 15 years.
And, the age of Gautam = x = 10 years.
Now,
The present age of Sita = 15 + 5 = 20 years. (Answer)
And, the present age of Gautam = 10 + 5 = 15 years. (Answer)

10) An employee at a magazine company calls existing customers to renew
their subscriptions. For existing customers, employees earn 3 points for
renewing a subscription and earn-2 points for not renewing a subscription
After an hour, an employee renews 4 existing subscriptions and does not
renew 7 existing subscriptions. Which of the following is the expression
that represents this situation? *
O A 4(3) +-7(2)
O B 4(-2) + 7(3)
O C4(3) + 7(-2)
O D3(4) + 2(-7)
Answer:
C
Step-by-step explanation:
since the employee earns 3 points for every renewal and he renews 4 you must multiply those together. then you need to add the loss of points (-2) times the number of nonrenewal customers (7).

Can anybody help and explain this? (Part a and b)
Answer:
Step-by-step explanation:
Part A
Given equation of the circle is,
x² + y² - 4x + 2y = b
Standard equation of the circle is given by,
(x - h)² + (y - k)² = r²
Here, (h, k) is the center and r = radius of the circle
Now we will convert this equation into a standard equation of the circle,
x² - 4x + y² + 2y = b
x² - 2(2x) + 2² + y² + 2y + 1² = b + 2² + 1²
(x² - 2(2x) + 4) + (y² + 2y + 1) = b + 4 + 1
(x - 2)² + (y + 1)² = √(b + 5)²
Therefore, (2, -1) will be the center of the given circle.
y-coordinate of the circle = -1
Part B
Since, radius of the circle is 7 units,
Therefore, [tex]\sqrt{b+5}=7[/tex]
b + 5 = 49
b = 49 - 5
b = 44

Annie earns $15 per hour babysitting. How many hours will it take her to earn $60?
Answer:
4 hours
Step-by-step explanation:
15 x 4 = 60
$60
Answer:
4 hours.
Step-by-step explanation:
We are looking for the amount of money Annie will need to earn 60.
Let the equation be 15+x=60.
The equation could be represented as 15+x=60, or 60-15=x.
The easier solution would be to subtract.
When we subtract 60-15 we get 45, therefore the value of x is 45 making the statements true.
15+45=60 and 60-15=45 as well.
We know she earns 15 an hour, so we have to see how many 15 we can add up to get to 60.
15+15+15+15=60, therefore she will need to work 4 hours.
The line y=3x creates an acute angle theta when it crosses the x-axis, Find the exact value of sec theta
Answer:
Sec(θ) = 3
Step-by-step explanation:
First, we know that:
Sec(x) = 1/Cos(x)
Now we have an angle θ in the intersection between the line y = 3x and the x-axis.
Here we can think of this as a triangle rectangle, such that:
x is the adjacent cathetus to θ
y is the opposite cathetus to θ
y = 3*x is the hypotenuse.
Here we also need to remember the relation:
Cos(θ) = (adjacent cathetus)/(hypotenuse)
Then we will get:
Cos(θ) = x/(3*x) = 1/3
If we multiply both sides by 3, we get:
Cos(θ)*3 = (1/3)*3 = 1
Cos(θ)*3 = 1
Now we can divide both sides by Cos(θ)
[Cos(θ)*3]/Cos(θ) = 1/Cos(θ)
3 = 1/Cos(θ)
And 1/Cos(θ) = Sec(θ)
Then:
3 = Sec(θ)
The exact value of sec theta is 3.

In a lottery, the top cash prize was $615 million, going to three lucky winners. Players pick four different numbers from 1 to 59 and one number from 1 to 49 . A player wins a minimum award of $225 by correctly matching three numbers drawn from the white balls (1 through 59 ) and matching the number on the gold ball (1 through 49 ). What is the probability of winning the minimum award?
Answer:
10063571 out of 593750689 or 1.69491525424%
Step-by-step explanation:
To find probability when all variables are known, you can just multiply the numbers you need. In this case we multiply 59 * 59 * 59 *49 since these are the balls we are picking from. We can find the chance of the top prize by multiplying all the numbers. 59 * 59 * 59 * 59 * 49
