Answer:
C) 4 pencils for each student
D) 8 students per team
Step-by-step explanation:
A unit rate is the number of unit of the first type of a quantity corresponding to one unit of the second type of quantity.
That is, if a and b are two quantities,
Then, unit rate of quantity a = x units of 'a' per 1 unit of 'b' or x units of 'a' for 1 unit of 'b'
By the above statement,
The example of unit rates from the given options are,
4 pencils for each student,
8 students per team
Complementary angles add up to 90 degrees.
So to find A you would need to add A and B together and equal it to 90 (3x+25+5x-7=90)
Combine like terms together (8x+18=90)
Subtract 18 from night sides (8x=72)
Divide by 8 on both sides (x=9)
Then to find A substitute x into its equation (3(9)+25)=(27+25)=52
A=52 I think
I think the answer is b. cos(pi theta)= -0.6
