Use the law of cosines to find the value of cos theta. round your answer to two decimal places

REY [17]

Answer:

The correct answer option is B. 0.21.

Step-by-step explanation:

We are to find the value of $cos \theta$ using the law of cosines.

We know that the formula of the cosine rule is given by:

$c ^ 2 = a ^ 2 + b ^ 2 - 2 a b cos C$

So substituting the given values in the above formula:

$10.9 ^ 2 = 5.8 ^ 2 + 10.5 ^ 2 - 2 (5.8) (10.5) cos C$

$118.81=33.64+110.25-121.8cosC$

$118.81 - (33.64+110.25) = -121.8cosC$

$118.81-143.86=-121.8cosC$

$cosC=\frac{-25.05}{-121.8}$

cos C = 0.21

a fair number cube labeld 1,2,3,4,5,6 is rolled a hundred times. about how many times could you expect to roll a three?

Vsevolod [243]

So probability is (desired outcomes)/(total possitlble outcomes)
desired is 1 since 3 appaears once on the cube
6 total possible

so probaity of rolling a3 is 1/6

100 times
100 times 1/6=100/6=16 and 2/3 times
round up
17 times

A scale drawing of a living room is shown below 5.5 inches and 3 inches scale 1:30 what is the area of the actual living room? R

Ostrovityanka [42]

Answer:

14850 inches

Step-by-step explanation:

The complete question is...

A scale drawing of a living room is shown below:

A rectangle is shown. The length of the rectangle is labeled 5.5 inches. The width of the rectangle is labeled 3 inches. The scale is 1 to 30.

What is the area of the actual living room in square feet? Round your answer to the nearest whole number.

The ratio of the scale = 1:30

This means that the dimensions of the drawing has been reduced to 1/30 of the actual building's dimensions.

We first scale up the drawing to 30 times to get the dimensions of the actual building.

The length on the drawing = 5.5 inches

The real length of the actual building = 5.5 x 30 = 165 inches

The width of the drawing = 3 inches

The width of the actual building = 3 x 30 = 90 inches

The area of the actual building = length x width

==> 165 x 90 = 14850 inches
