In a right triangle, the value of cos B = 3/5. What is the value of sin B?

ozzi

Answer:

4/5

Step-by-step explanation:

cos B = 3/5

cos Ф = adjacent/hypothesis

hypothesis ² = adjacent² + opposite²

5²= 3²+ o²

25 = 9+o²

25-9=o²

16 = o²

√16 = o = 4

Sin B = opposite/hypothesis = 4/5

You place three orders for 100 soccer balls which cost $22 per ball. You receive all 300 balls. There is a delivery charge of $2

julsineya [31]

Answer:

Average cost per ball: $22.2

Step-by-step explanation:

Cost per ball: $22

Cost of 300 balls: 300 × 22 = $6600

Total No. of Orders: 3

Delivery fee per order: $20

Total Delievery fee: 20 × 3 =$60

Total cost including delivery cost: $6600 + $60 = $6660

$Average cost per ball = \frac{Total cost}{No. of balls}$

$Average cost per ball = \frac{6660}{300}$

$Average cost per ball = $22.2$
