Answer:
correct option: 2 -> It would decrease.
Step-by-step explanation:
If the amount of gas is the same, the following relation needs to be constant:
So, If the pressure is constant, the volume and the temperature are directly proportional (if one increases, the other also increases).
Then, an decrease of 3 times in the volume would cause an decrease of 3 times in the temperature.
So the correct option is 2.: It would decrease.
Answer:
20%
Step-by-step explanation:
Given parameters:
Marked price = Rs. 100
Selling price = Rs. 80
Unknown:
Discount rate = ?
Solution:
The price on the label of an article is the marked price;
Discount amount = Marked price - selling price
= Rs. 100 - Rs. 80
= Rs. 20
Discount rate =
Discount rate = x 100 = 20%
The area bounded by the curve, x-axis and y-axis of the function y = √(x + 3) is 2√3
<h3>How to determine the area bounded by the curve, x-axis and y-axis?</h3>
The curve is given as:
y = √(x + 3)
The area bounded by the curve, x-axis and y-axis is when x = 0 and y = 0
When y = 0, we have:
0 = √(x + 3)
This gives
x = -3
So, we set up the following integral
A = ∫ f(x) d(x) (Interval a to b)
This gives
A = ∫ √(x + 3) d(x) (Interval -3 to 0)
When the above is integrated, we have:
A = 1/3 * [2(x + 3)^(3/2)] (Interval -3 to 0)
Expand
A = 1/3 * [2(0 + 3)^3/2 - 2(-3 + 3)^3/2]
This gives
A = 1/3 * 2(3)^3/2
Apply the law of indices
A = 2(3)^1/2
Rewrite as:
A = 2√3 or 3.46
Hence, the area bounded by the curve, x-axis and y-axis of the function y = √(x + 3) is 2√3

You must divide 2400 by 4 to find your answer. If you know 24/4, then it should be easy. 24 divided by 4 is 6, so add those 2 zeros and you should get 600 pennies for each student.
