Answer:
<h3>6</h3>
Step-by-step explanation:
Given the expression sin(9z − 1) = cos(6z + 1), for 0 < z ≤ 90, we are to find z
Note that sin theta = cos(90-thetsa)
sin(9z − 1) = cos(6z + 1)
cos (90 - (9z-1)) = cos(6z + 1)
cos (90 - 9z+1)) = cos(6z + 1)
cos (91-9z) = cos(6z + 1)
Cos will cancel out to have;
91-9z = 6z+1
-9z - 6z = 1-91
-15z = -90
z = 90/15
z = 6
Hence the value of z is 6
Answer:
x = 5
Step-by-step explanation:
Since these are similar triangles all you need to do is figure out how much "x" has gotten smaller.
First take the line DE length (16) and divide it by line BC (8)
16 / 8 = 2
Now divide line BD by 2
10 / 2 = 5
x = 5
Amy earns $0.16 per unit for the work she does. For all units she produces in a week over 1,000, she receives $0.26. What were her weekly earnings if she produced 1,725 units in one week?
Answer: The number of units produced by Amy in one week 
For the first 1000 units, she earns $0.16 per unit. Therefore, her total earning's for the first 1000 units is $0.16 x 1000 = $160
For the remaining 1725 - 1000 = 725 units, she earns $0.26. Therefore, her total earning for the 725 units is $0.26 x 725 = $188.5
Therefore, Amy's total for one week = $160 + $188.5 = $348.5
Hence, the option b. $348.50 is correct
