Answer:
3 minutes
Step-by-step explanation:
Let x represent Alysha's time to drive home from the market.
Speed and time are inversely proportional to each other (for the same distance), so we have ...
(walking speed)(walking time) = (driving speed)(driving time)
5(x +21) = (8·5)(x)
x +21 = 8x . . . . . . . . . divide by 5
21 = 7x . . . . . . . . subtract x
3 = x . . . . . . .divide by 7
It takes Alysha 3 minutes to drive home from the market.

Solve for the first variable in one of the equations, then substitute the result into the other equation.
The value of the expression 1/√2 + π where the given parameters are π = 3.141 and √2 = 1.414 is 3.848
<h3>How to evaluate the expression?</h3>
The given parameters are
π = 3.141
√2 = 1.414
The expression to evaluate is given as:
1/√2 + π
Start by substituting π = 3.141 and √2 = 1.414 in the expressions 1/√2 + π
1/√2 + π = 1/1.414 + 3.141
Evaluate the quotient
1/√2 + π = 0.707 + 3.141
Evaluate the sum
1/√2 + π = 3.848
Hence, the value of the expression 1/√2 + π where the given parameters are π = 3.141 and √2 = 1.414 is 3.848

By taking π = 3.141 and √2 = 1.414, evaluate 1/√2 + π up to three places of decimals.
There is no power of 4 that is to 0
Answer:
18
Step-by-step explanation:
This is because when you find the prime factors, you can take out the ones that they have together.
In this case:
9 - 3 * 3
6 - 3 * 2
2 - 2
So notice that each number has a maximum of 2 3s and 1 2, thus, you can multiple 3 * 3 * 2
