Answer:
42
Step-by-step explanation:
Number of students whose favorite class is Math:
60*0.85=51
Number of students whose favorite class is Science:
15% is equal to 0.15.
60*0.15=9
Subtract number of students who like science from number of students who like math.
51-9=42
42 more students in the survey prefer math over science.
Answer:
$2,400
Step-by-step explanation:
1) lets use the i=prt formula
where i=interest
p=principal
r=rate
t=time
the principal here is $6000(starting amount)
rate is 0.08
and time is 5
so
I=0.08*5*6000
I=2400
you will gain an interest of $2400
26% of what = 45.50.....
0.26x = 45.50
x = 45.50/0.26
x = 175 total sales
Step-by-step explanation:
sum of two interior angles is equal to one exterior angle....this implies that,
(6x+4) +(5x+2)= 12x-4
11x+6=12x-4.......make X the subject
11x-12x=-4-6
-x= -10......divide both sides by -1
x=10
