Answer:
8 hours
Step-by-step explanation:
If Jackie wants to burn 2000 calories in one week but only burns 250 calories per hour
then, to solve how many hours you have to divide
2000/250= 8
therefor Jackie has to do aerobics for 8 hours that week to burn 2000 calories
3.141562.... And it goes on and on and on
V = u + at
u = 0
v = 0 + 1.5*5
v = 7.5 m/s
final velocity is 7.5 m/s
s = ut + 0.5at^2
s = 0 + (0.5*1.5*5^2)
s = (0.5*1.5*25)
s = 18.75 m
total travel distance is 18.75 m.
Answer:
29m+37?
Step-by-step explanation:
<em>Pemdas</em>
5m+3(8m+7)+4^2
Parentheses first: 5m+24m+21+4^2
Exponents next: 5m+24m+21+16
No multiplication or division so addition is last:
29m+37
These two can't add together because one has a variable.
Answer:
Numbers of students at a primary school before= 240
Number of increased students =42
Again,
Increased number of students in percent(%)= 42/240×100%= 17.5%
Therefore 17.5% students are increased this year.
