Answer:
Option C
63
Step-by-step explanation:
Using the given equation y = 0.338x − 1.387 and since you're given the the number of commercials, you substitute this for y hence
20= 0.338x − 1.3877
20+1.3877=0.338x
0.338x=21.3877
x=21.3877/0.338=63.27514793
Rounding off, x=63. \the question says x represents the minutes spent hence the answer is 63
Remember SOHCAHTOA
Sine- opposite/hypotenuse
Cosine- adjacent/hypotenuse
Tangent- opposite/adjacent
Look at the angle (x) you are trying to figure out and pick which one of these it is.
In your calculator, do the equation first to get a decimal
Then press whichever one you chose on the calculator, so if you got like 0.2 by doing opposite/adjacent for tangent, you would type in 0.2 and then the TAN button
hope this makes sense!!
Answer:
1073.38
Step-by-step explanation:
975 × 0.01 = 9.75
9.75 + 975 = 984.75
984.75 × 0.09 = 88.6275
88.6275 + 984.75 = <u>1073.38</u>
the answer is c: .... 72+8w
