Answer:
sqrt(sqrt(x))
Step-by-step explanation:
The problem statement tells you how to do it: take the square root, then the square root of that, using the square root function twice and making the result of one the argument of the other.
The answer is 25
If you divide 25 by .32 or 32%
25x.32= 8
The end result would be 8
Answer:
1/27000
Step-by-step explanation:
= 3^-3 × 10^-3
= 1/3³ × 1/10³
= 1/27 × 1/1000
= 1/27000
Hope this helped!
Answer:The rate of the slower hiker is 2.2 mph and the rate of the faster hiker is 5.5 mph
Explanation:
One hiker walks 3.3 mph faster than the other.
Suppose, the speed of the slower hiker is mph.
So, the speed of the faster hiker will be:
Both hikers are walking toward each other and meet in 10 hours.
We know that,
So, the distance walked by the slower hiker in 10 hours miles and the distance walked by the faster hiker in 10 hours
miles.
Given that, they were 77 miles apart in the beginning. So the equation will be
Answer:
Length= 20
Width= 4
Step-by-step explanation:
First, you can turn this into an equation:
Length= L
width= w
So L=5w
And using the area formula for rectangles, we get L*w=80.
Now, to solve, we only need to substitute 5w into L.
Now we have 5w^2=80. We divide by 5 on both sides to get w^2=16.
We take the square root of both sides. since the length and width of an rectangle cannot be negative, we are left with only w=4.
So plugging back in, we get L=20.
To check, 20*4=80.
