Answer:

57.5°

Step-by-step explanation:

For triangle ABC C = 90 Side AC = 13.5 Side BC = 8.6 Find the measure of angle B

We solve using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = Angle B

Opposite = Side AC 13.5

Adjacent = Side BC = 8.6

Hence:

tan θ = 13.5/8.6

θ = arc tan (13.5/8.6)

θ = 57.501354056°

Approximately = 57.5°

Therefore, Angle B = 57.5°

Sharkira went bowling with her friends.She paid $3 to rent shoes and then 4.75 for each game of bowling. If she spent a total of

9966 [12]

$21 - $3 = $18

$18 - $4.75 = $13.25

$13.25 - $4.75 = $8.50

$8.50 - $4.75 = $3.75

Which means that she played 3 games, and has $3.75 left over.

But if you were to divide 4.75 from 21 it would equal 4 games and $2 left over.

21 - 4.75 = 16. 25

16.25 - 4.75 = 11.50

11.50 - 4.75 = 6.75

6.75 - 4.75 = 2

4 games and $2 dollars left over.

A greeting card company can produce a box of cards for $7.50. If the initial investment by the company was $50,000, how many box

larisa86 [58]

Answer:

If cost of one box of card is $7.50 then the no of cards produced is 6667 cards and if cost of one box of card is $10.50 then the no of cards produced is 4762 cards

Step-by-step explanation:

The cost of one box of cards = $7.50

Initial investment = $50,000

No of box of cards produced = Initial investment / cost of one box of card

No of box of cards produced = 50,000/7.50

No of box of cards produced = 6667 cards.

if the cost of one box of cards is increased = $10.50

No of box of cards produced = Initial investment / cost of one box of card

No of box of cards produced = 50,000/10.50

No of box of cards produced = 4762 cards.

So, if cost of one box of card is $7.50 then the no of cards produced is 6667 cards and if cost of one box of card is $10.50 then the no of cards produced is 4762 cards
