First, you have to solve t(x) when x=4, because the crew is working 4 scripts. Which is t(x)=4+6
t(x)=10
Then, you plug in t(x) to c(x).
c(x)=2(10)+4
c(x)=24
.05c+.3s=10.25, c+s=100, c=100-s (c is for cards that don't sing and s is for those that do :P)
.05c+.3s=10.25 and c=100-s makes the equation become:
.05(100-s)+.3s=10.25
5-.05s+.3s=10.25
.25s=5.25
s=21, and since c=100-s
c=79
So she bought 21 of the more expensive singing cards...
Answer:
D) 22534 m
Step-by-step explanation:
<em>The figure forms a Z shape where the top line and bottom line are parallel. Therefore the angle with the coastline, inside the triangle will be 16.5°.</em>
<em>We have to find the hypotenuse which is the side opposite to the 90 degree angle.</em>
<em>Now this can be solved through sin formula</em>
<u>Step 1: Write all the data</u>
Angle = 16.5°
Opposite = 6400
Hypotenuse = ?
<u>Step 2: Use the sin formula</u>
Sin (Angle) = Opposite/Hypotenuse
Sin (16.5) = 6400/Hypotenuse
<u>Step 3: Solve</u>
Hypotenuse = 6400/sin(16.5)
Hypotenuse = 22533.99 rounded off to 22534 m
The jet has to fly 22534 m before it reaches the coastline.
Therefore, option D is the correct answer.
