Answer:
42
Step-by-step explanation:
its 41.8, but you cant take 41.8 trips, so you have to round it
3 x 60 (because there are 60 minutes in an hour) = 180. then 180 + 15 = 195. 500 / 195 = 2.6 miles per minute. 2.5 x 60 since its asking for miles per hour, is 156. he goes 156 miles per hour.
Answer:
a.) First check on the height of the bar that ranges between 20 and 24 which is 6. The 6 is the number of students who bought 20 books or more, so get the percentage of those students who bought 20 or more books; divide 6 which is the number of students who bought 20 books or more with the total number of students which is 40 then multiply with 100.
% of students who bought 20 or more books = 6/40 ×100
=15
Step-by-step explanation:
b.) Find the area of a trapezium
= 1/2 × {a+b} × h
= 1/2 × {9 + 13} ×12
= 132
= 1/2 × {13 + 6} × 12
= 108
Mean no. of books bought = 132 + 108
= 240

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
