Generally
From the z-table
And
=>
=>
That’s a simple proportion.
Where
is the unknown height of the person.
Answer: The answer, rounded to the nearest tenth, is 113.0
Step-by-step explanation:
This is the formula for calculating the circumference of a circle:
C= 2pi r
R is the radius. Since the path is 2 feet wide, we can add 2 to the radius of the garden to get the radius of the whole path and garden.
2+4=6 so the radius for the total area of the garden and path is 6 feet.
Now we need to plug 6 into the formula to find circumference.
The list of equal fractions could be very long, but here are a few that are equal to 4/5.
4*2 = 8
5*2 = 10
8/10 = 4/5
64/80 = 4/5
16/20 = 4/5
Answer:
X=-1
Step-by-step explanation:
-5x+1=6
change the signs
5x-1=-6
add 1 to - 6
5x = -5
divide both sides by 5
X=-1
