Answer:
about 14.28% for 1/7th
Step-by-step explanation:
Formula for the area of a circle:
A = πr² [A = area r = radius]
The radius is
(half) the diameter. Since the diameter = 10cm, the radius = 5cm.
You know:
r = 5cm Substitute/plug this into the equation
A = πr²
A = π(5)²
A = 25π -> A = 25(3.14)
A = 78.5cm²
Answer:
Step-by-step explanation:
In math, a term is a combination of coefficients, constants and /or variables, each combination being separated by either a + sign or a - sign.
Answer: 20
Step-by-step explanation:
Assuming g(x) = -4x + 1,
( -4 (-4) + 1) - (-4 + 1)
= (16 + 1) - (-3)
= 17 + 3
= 20
Answer:
<h2> D=C/4</h2>
Step-by-step explanation:
Given that elevation of the cities are
A=72 feet
C=24 feet
D=1/4 of C
The expression for the elevation of city D is
D=C/4
substituting C=24 in the expression we have
D=24/4
D=6
The answer is positive because the elevation is above sea level
