When Billy's asked how old he is, he replies, "In two years i will be twice as old as i was 5 years ago." How old is he?
Answers
12 years old.
• Let the present age of Billy be represented by x.
• In two years, Billy will be: = x + 2
• Since in 2 years, he will be twice as old as he was 5 years ago, this will be:
x + 2 = 2(x - 5)
The equation to solve the question is:
x + 2 = 2(x - 5)
x + 2 = 2x- 10
Collect like terms
2x - x = 2 + 10
x = 12
• Billy is 12 years old.

One of the legs of a right triangle measures 2 cm and its hypotenuse measures 9 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.
Answers
Answer:
The measure of the other leg = 8.8 cm
Explanation:
Given - One of the legs of a right triangle measures 2 cm and its hypotenuse measures 9 cm.
To find - Find the measure of the other leg.
Proof -
We know that,
For a right angle triangle,
Apply The Pythagoras Theorem , which states that
(Hypotenuse)² = (Base)² + (Perpendicular)²
Given that,
Hypotenuse = 9 cm
One leg = 2 cm
Let us assume that,
One leg is base and another leg is Perpendicular.
We also can suppose vice-verse, it does not affect the solution.
Now,
(Hypotenuse)² = (Base)² + (Perpendicular)²
⇒(9)² = (2)² + (Perpendicular)²
⇒81 = 4 + (Perpendicular)²
⇒81 - 4 = (Perpendicular)²
⇒77 = (Perpendicular)²
⇒√77 = Perpendicular
⇒Perpendicular = 8.775 ≈ 8.8
∴ we get
The measure of the other leg = 8.8 cm
Suppose two drugs are routinely used for the treatment of thyroid dysfunction. Drug X is known to cure the disorder 75% of the time and costs $88.
Drug Y is known to cure the disorder 60% of the time and costs $75. The two drugs work independent of each other. The two treatment plans are as
follows:
Plan A: Treatment with Drug X-if not effective treatment with Drug Y
Plan B: Treatment with Drug Yếif not effective, treatment with Drug X
28
Select the correct answer.
From the perspective of an insurance company paying for the treatment, which is the best decision?
ОА.
Based on the overall probability of a cure, plan A should be selected over plan B.
ОВ.
Based on the overall probability of a cure, plan B should be selected over plan A.
OC. Based on the overall cost of treatment plan A should be selected over plan B.
OD
Based on the overall cost of treatment plan B should be selected over plan A.
Answers
Answer:
The correct answer is A)
Explanation:
This is because the chances that the company will prevent additional expenses on the treatment of the ailment is 75% which is higher than that of the other drug whose effectiveness is at best 40% less than the expected results and 15% reduced than drug A.
In other words, if the drug b is used first, there is an increased chance that the company will spend more money to treat the ailment.

Set both equation equal:
5x = -15x + 3000
20x = 3000
x = 150
Plug into any equation because both are equal anyway:
y = 5x
y = 5(150)
y = 750
(a, b) --> (x, y)
The point is (150, 750) and b = 750
