In a survey, a group of students were asked to name their favorite day of the week. There were 8 students who chose “other”.
lara [203]
5 % of the students choose other. 95% choose either Saturday or Sunday. 
Let x be the number of students who participated.

(5/100) * x = 8  Multiply both sides by 100
5 * x = 8*100
5*x = 800  Divide by 5
x = 800/5
x = 160 students participated in the survey <<<<< Answer

Help pls i need this done asap ty
zhuklara [117]

Answer:

b) 7.89*10^4

c) 3.15*10^3

Step-by-step explanation:

2-42)

the coefficient in scientific notation (the number that is not 10^x) has to be greater or equal to 1 and less than 10. so c and b are incorrect.

b) 0.789*10^5

c) 31.5*10^2

b) 0.789*10^5

in order to make 0.789 greater than 1, I would just multiply it by 10. shown below

=0.789*10*10*10*10*10

=7.89*10*10*10*10

=7.89*10^4

c) 31.5*10^2

same concept but this time divide by 10 to make 3.15 which will add another *10 to the exponent

=31.5*10*10

=3.15*10*10*10

=3.15*10^3

Find the value of y. this is dud tdy help plss
spin [16.1K]

Answer:

y is B. 82 degrees (and for extra, x is 54 degrees)

Step-by-step explanation:

The angles shown are complementary, which means they equal 180 degrees. Subtract 73 from 180 to get 107 degrees for the other angle in this set. After that subtract 25 from 107 to get y, which is 82 degrees.

(For x, just subtract 19 from 73 to get 54 degrees.)
