Answer:
<h2>49.5°</h2>
Step-by-step explanation:
Given the trigonometry function as shown sin W = 0.79, to get W, the following steps must be followed.
Step 1: Take the arcsin of both sides of the equation

Step 2: Use a calculator to get the resulting value of W

 (to nearest tenth of a degree)
 (to nearest tenth of a degree)
This gives the acute angle needed.
Note that acute angle are angles that are less than 90°

Answer:
-12
Step-by-step explanation:
x = 12-3a
When a=8:
x = 12-3(8)
x = 12 - 24
x = -12
 
        
             
        
        
        
Answer:
Step-by-step explanation:
<em>Refer to attached</em>
- Height of plants (h) >> Frequency >> Midpoint >> Frequency x midpoint
- 0 <h < 10	>>  1  >> 5 >> 5
- 10 <h < 20 >>	4 >>	15 >>  60
- 20 <h < 30 >>	7 >>	25 >> 175
- 30 <h < 40 >>	2 >>	35 >> 70
- 40 <h < 50 >>	3 >>	45 >> 135
- 50 <h < 60 >> 3 >> 55 >> 165
Sum of frequencies = 20
Sum of frequency x midpoint product = 610

Answer:
Step-by-step explanation:
The correct question is
Zena needs a salesperson. Salesperson A is offering his services for an initial $50 in addition to $5 per hour. salesperson B is offering her services for an initial $40 in addition to $7 per hour. When will the two coaches charge the same amount of money?
Let
x ----> the number of hours
y ----> the total charge
we know that
Salesperson A
 ------> equation A
Salesperson B
 ------> equation B
To find out when the two coaches charge the same amount of money, equate equation A and equation B and solve for x
7x+40=5x+50
7x-5x=50-40
2x=10
<h2>x=5 hours i think just im not sure but i tried</h2>
