1.71

Step-by-step explanation:

Cosine = adjacent/hypotenuse

cos 70 = x/5

cos 70 = 0.3420201433

0.3420201433(5) = 1.710100716

x=1.710100716

x=1.71

x = 4.56

Step-by-step explanation:

Angle A = 20 degrees

x = BC

sin(20) = x/5

multiply 5 on both sides

5sin(20) = x

x = 4.56

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
