Answer:

1/6 (=0.1667)

Step-by-step explanation:

If we look just at weeks 2, 3 and 4:

Week 2: 40 regular + 6 overtime

Week 3: 40 regular + 10 overtime

Week 4: 40 regular + 4 overtime

Total number of regular hours = 40 + 40 + 40 = 120

Total number of overtime hours = 6 + 10 + 4 = 20

number of overtime hours as a fraction of number of regular hours

= number of overtime hours / number of regular hours

= 20 / 120 (simplify by dividing numerator and denominator by 20)

= 1/6 (=0.1667)

What is the approximate value of x in the diagram below? (Hint: You will need

Delicious77 [7]

Answer:

B. 39.59

Step-by-step explanation:

So 43 degrees, you know the length of the opposite side (27) and the angle (43 degrees), the only unknown is the hypotenuse. So you're looking for a trigonometric ratio that uses the angle (all of them do, except technically the inverse don't), the opposite side, and the hypotenuse. Sine is defined as $\frac{opposite}{hypotenuse}$ . So let's plug in known values:

$sin(43) = \frac{27}{x}$

Multiply both sides by x

$sin(43) * x = 27$

divide both sides by sin(43)

$x=\frac{27}{sin(43)}$

Normally I would use a calculator, but in this case I'll use the approximation given in the problem of 0.682

$x=\frac{27}{0.682}$

simplify the fraction

$x\approx39.59$

What is the length of the radius? startfraction 6 over 85 endfraction startfraction 85 over 12 endfraction startfraction 121 ove

melomori [17]

The length of the radius will be 22 units.

<h3>What is the radius?</h3>

The radius of a circle is defined as the distance of the center of the circle to its outer layer. It is a locus of a point present at some distance from the center point.

Now from the question, we have an expression:

$r=(\dfrac{6}{85} )\times(\dfrac{85}{12} )\times (\dfrac{121}{36} )\times (\dfrac{157}{12} )$
