(Right angle) Trigonometry <br> please help!
kozerog [31]

Answer:

A = 41.4°

Step-by-step explanation:

Reference angle = A

Length of Adjacent side = 6

Length of Hypotenuse = 8

Apply the trigonometric function, CAH.

Cos A = Adj/Hyp

Substitute

Cos(A) = \frac{6}{8}

A = Cos^{-1}(\frac{6}{8})

A = 41.4° (approximated to the nearest tenth)

Answer:7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce

Step-by-step explanation:1/4 + 5/8 = 2/8 + 5/8 = 7/8

= amount used for pepper and tomatoes

2 1/2 - 3/4 = 5/2-3/4 = 10/4 -3/4 = 7/4

= total amount used

so

7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce

Ray earns $15 an hour for up to 40 hours a week. If he works more than 40 hours a week, he is paid time and a half. That means R
nekit [7.7K]

Answer:

$7.50

Step-by-step explanation:

His normal pay is $15/h

Find the OT pay:

OT pay is 150% of his normal pay. Convert 150% to a decimal by dividing by 100 to find the rate in decimal form.

150%/100 = 1.5

Multiply his normal pay by the rate in decimal form.

$15 X 1.5 = $22.5

His OT pay is $22.5/h.

Additional money

= (OT pay) - (Normal pay)

= $22.5 - $15

= $7.5

We always use two decimal places for money.

$7.5 = $7.50

For every hour he works over 40 hours, he is paid an additional $7.50.
