First you plug in the data to the formula. So it will be 2(1/3+1/2). You then want to add the fractions together but must first find the common denominator which will be 6. So it is 2(2/6+3/6). The fractions then add up to be 5/6. So all you have to do is multiply it by 2 to get 5/3 which simplifies to 1 2/3 so it is D.
Answer:
<em>122.46 cm² </em>
Step-by-step explanation:
A =
~~~~~~~~~
= 8 cm
= 5 cm
A = 3.14 ( 8² - 5² ) ≈ <em>122.46 cm²</em>
Assuming that you got the numbers right and that I did my calculations right, then the answer is <span>2998.45 tons.</span>
Sin 27=11/a
a=11/sin 27
a=24.2
1/sqrt8 = 4(m+2)
1/sqrt8 = 4m +8
1 = (4m +8)*sqrt8
1 = 4m*sqrt8 +8sqrt8
sqrt8 = 2sqrt2
1 - 16sqrt2 = (8sqrt2)*m
m = (1 - 16sqrt2)/8sqrt2
m = (1 -16sqrt2)*sqrt2 / (8*2)
m = (sqrt2 -32)/16
hope this will help you
