If sin θ = 2 over 7 and tan θ > 0, what is the value of cos θ?
sergey [27]
Sin θ = 2 / 7
tan θ > 0
cos θ = ?

sin θ = opposite / hypotenuse
tan θ = opposite / adjacent
cos θ = adjacent / hypotenuse

short leg = opposite = 2
hypotenuse = 7
long leg = adjacent = ?

adjacent = √(7² - 2²)
adjacent = √(49 - 4)
adjacent = √45
adjacent = √9 * 5
adjacent = 3 √5

cos θ = adjacent / hypotenuse
cos θ = 3√5 / 7

Ms. Fontanges wants to put a line of bricks along the back edge of her yard. She needs 35 feet of bricks. The bricks she wants t
Oliga [24]

Answer:

$41.16

Step-by-step explanation:

Length of bricks required = 35 feet, length of brick sold = 10 inches, cost of 10 inches brick = $0.98 per brick

Total number of brick required to build the back yard = Length of bricks required ÷ Length of brick sold

1 ft = 12 inches

Number of brick required = (35 * 12) ÷ 10

Number of bricks required = 42 bricks

Cost of brick required = Per length cost of brick * Number of bricks required

Cost of brick required = 0.98 * 42

Cost of brick required = $41.16

Ms. Fontanges would spend $41.16 on the purchase of bricks

Kaitlin makes $13.15 per hour. If she works more than 40 hours in a week, she gets paid time and a half. Kaitlin gets a paycheck
Dmitrij [34]

Answer: 8 hours

Step-by-step explanation:

The pay is for 2 weeks which means that she worked for 80 hours.

At 80 hours, the regular income she should make is:

= 80 * 13.15

= $1,052

The total she made from overtime is therefore:

= 1,209.84 - 1,052

= $157.84

When she works overtime, she gets paid at a rate of a time and half. This means she gets:

= 13.15 * 1.5

= $19.73

The hours of overtime she worked is therefore:

= 157.84/19.73

= 8 hours
