First, set up a proportion. 10.3% is the percentage of students who cancelled, but the question is asking for the students who are attending, so let’s use 89.7% to make it easier. The proportion would be x over 58 is equal to 89.7% over 100%. Multiply 58 by 89.7, giving you 5,202.6. Next, take 5,202.6 and divide it by 100. This should give you 52. 026, but it’s best to round this to 52. 52 students actually attend the art class, making this your final answer.
Answer: 296 or 592
Step-by-step explanation:
Answer:
(√2 − √6) / 4
Step-by-step explanation:
Rewrite using special angles.
sin(-11π/12)
sin((4−15)π/12)
sin(4π/12 − 15π/12)
sin(π/3 − 5π/4)
Use angle difference formula:
sin(π/3) cos(5π/4) − sin(5π/4) cos(π/3)
Evaluate:
(√3/2) (-√2/2) − (-√2/2) (1/2)
-√6/4 + √2/4
(√2 − √6) / 4
Answer:
y(x)=0.8x+2.1
x=12 miles
Step-by-step explanation:
Let x represent the number of miles covered and with a fixed charge of 2.1 irrespective of miles covered then the equation can be written as
y(x)=0.8x+2.1
Substituting y(x) with 11.7 then
11.7=0.8x+2.1
0.8x=11.7-2.1=9.6
X=9.6/0.8=12 miles
