BC= Round your answer to the nearest hundredth.

mrs_skeptik [129]

Answer:

BC ≈ 1.71

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos70° = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{BC}{5}$

Multiply both sides by 5

5 × cos70° = BC , thus

BC ≈ 1.71 ( to the nearest hundredth )

a motorist starts from O nd moves in a direction 030° for 36km.he then moves 7km towards the west .how far east his he now from

gavmur [86]

Answer:

11 km

Step-by-step explanation:

Assuming your "direction 030°" is a bearing measured clockwise from north, the amount the motorist moved east on the first leg of the journey was ...

(36 km)sin(30°) = 18 km

From that point, moving 7 km west makes his easterly position ...

18 km -7 km = 11 km . . . . east of O

_____

The sine of an angle is the ratio of the side opposite to the hypotenuse. You can find the length of the side opposite (the easterly motion) by multiplying the sine of the bearing angle by the distance of travel. A diagram can help.

If a store sells 300 flat screen TVs and 30% of high definition, how many high definition TVs were sold?

Blababa [14]

90 Tv’s are high def! 300/100 = 3 (this is what 1% equals because there’s 100% total) so if we know 1% is 3 tv’s and 30% are high def, then we find out how many tv’s 30% is. so if 3 is 1% then 30 x 1= 30 then 30x3 = 90!

How to calculate the percentage?

miv72 [106K]

$\: \: \: \: \:$

How to calculate percentage of a number. Use the percentage formula: P% * X = Y

Convert the problem to an equation using the percentage formula: P% * X = Y.
P is 10%, X is 150, so the equation is 10% * 150 = Y.
Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

Multiply by 100 and add a percentage sign
0.876 = 0.876 * 100 = 87.6%
