Answer:
22.5
Step-by-step explanation:
start by doing 4 squared, since theirs an n on the 4 you have to leave the n attatched to 16 (4 squared is 16) then you have to subtract 10 from -36 and you get 46. after you do that you have to divided 16 from both sides. witch leaves you with n= 22.5
It is a valid sample because 10 people were chosen to participate.
On simplifying the given expression using the laws of exponents, we get → 15s⁻¹t⁶u⁻⁷v⁻⁵.
<h3>What are exponents?</h3>
An exponent refers to the number of times a number is multiplied by itself. Mathematically -
aˣ = a × a ×.... (x times)
Given is the following expression -
(9s⁰t⁷u⁰v⁻¹ . 5s⁰t⁰u²v⁰)/3stu⁹v⁴
We simplify the numerator separately and then the remaining question.
Assume that -
A = 9s⁰t⁷u⁰v⁻¹ × 5s⁰t⁰u²v⁰
B = 3stu⁹v⁴
Simplifying A, we get -
9s⁰t⁷u⁰v⁻¹ × 5s⁰t⁰u²v⁰
45 × s⁰⁺⁰ × t⁷⁺⁰ × u⁰⁺² × v⁻¹⁺⁰ [aˣ + aⁿ = aˣ⁺ⁿ]
45s⁰t⁷u²v⁻¹
Now, simplify → A/B
45s⁰t⁷u²v⁻¹ / 3stu⁹v⁴
15 x s⁰⁻¹ × t⁷⁻¹ × u²⁻⁹ × v⁻¹⁻⁴ [aˣ / aⁿ = aˣ ⁻ ⁿ]
15s⁻¹t⁶u⁻⁷v⁻⁵
Therefore, on simplifying the given expression using the laws of exponents, we get → 15s⁻¹t⁶u⁻⁷v⁻⁵.

First, start by transferring a liter to a gallon. 3.78 liters in 1 gallon.
This means they pay 1.65*3.78=6.24 euros per gallon of gasoline. If the conversion is 1 us dollar = .76 euros, set up a proportion where x$=6.24euros.... .76x=6.24.... x=$8.21
Next, do the reverse. One liter is .26 gallons, meaning we pay 3.90*.26=$1.01 for a liter of gas. Convert this back into euros by multiplying it by .76... 0.77 Euros
Yes, the situation as described is proportional.
Discussion:
According to the question:
- We are required to determine if the situation described in the question is proportional.
Since, Aisha pays $2 for each game she plays at the arcade.
In essence, the total amount of money paid by Aisha will depend on the number of games she plays. On this note, the situation is proportional.
