Answer:

A) \frac{\sin{23}}{6.2}=\frac{\sin{85}}{b}

Step-by-step explanation:

In order to use the Law of Sines, we must have a known angle and the known side opposite it.

The only side measure we have is that of AB, which is 6.2.  The angle opposite this is ∠C, which we do not have the measurement of.

We do have the measurement of ∠A and ∠B; we can use these to find the measure of ∠C.  We know that the sum of the measures of the angles in a triangle is 180°; this means

m∠C = 180-(72+85) = 180-157 = 23°

This makes the first ratio in the Law of Sines

\frac{\sin{23}}{6.2}

We are trying to find the measure of b.  This means we use the angle opposite b, ∠B; m∠B = 85°.  This gives us the ratio

\frac{\sin{85}}{b}

Together, this gives us the proportion

\frac{\sin{23}}{6.2}=\frac{\sin{85}}{b}

Answer:

\large\boxed{53.9ml=0.0539l}

Step-by-step explanation:

1l=1,000ml\to1ml=\dfrac{1}{1,000}l=0.001l\\\\\text{Therefore}\\\\53.9ml=53.9\cdot0.001l=0.0539l

Pierre is running 26 and 2/10 miles in the marathon. He has run 3/4 of the way. How far has he run?
Harman [31]
Pierre ran 19 and 13/20 miles.

Given:
marathon length : 26 2/10 miles
pierre's length ran : 3/4 of the way.

Multiply the fractions. 
Convert the marathon length from a mixed fraction into a fraction.
26 2/10 = ((26*10)+2)/10 = (260+2)/10 = 262/10

262/10 * 3/4 = (262*3) / (10*4) = 786/40 = 19 26/40

19 26/40 simplified to 19 13/20 miles

26 ÷ 2 = 13
40 ÷ 2 = 20

You will get 10 points! thanks
Marianna [84]

Answer: y=-1/6x+2

Step-by-step explanation: The point goes through (0,2), aka, the b point in y=mx+b (The slope intercept form). Then because it’s proceeding downwards, we know that the slope is negative. So down one, over 6. This make its -1/6.
