Answer:
84.9
Step-by-step explanation:
The weighted mean is given by the sum of the products of each grade by its respective weight. If the first four grades correspond to 15% of the final grade each, and the final exam is equivalent to 40% of the final grade, Michael's final grade is:
Michael's final weighted mean is 84.9.
We know that
[the area of a circle]=pi*r²
for r=4 ft
[the area of a circle]=pi*4²------> 50.24 ft²
if 2π radians ( full circle) has an area of-----------------> 50.24 ft²
5π/2 radians--------------------------------------> X ft ²
X=(5π/2)*50.24/2π-------> 62.8 ft²
the answer is
62.8 ft²
Answer:
6.75
Step-by-step explanation:
10.00-3.25= 5.75
the first pieces of information are irrelevant
Basically plug in 2 where y is and 5 where X is
3(5)(2) - 4(2) , the parentheses are there to multiply
30-8
22
Answer:
x=3
Step-by-step explanation:
6 10
---------- = ------------
6+x 15
using cross products
6 * 15 = 10 * (6+x)
90 = 60+10x
subtract 60 from each side
90-60 = 60+10x-60
30 = 10x
divide by 10
30/10 = 10x/10
3=x
