Given:
An athlete who makes 
laps in 3 mins 45 seconds on a 400m field.
To find:
The speed of the athlete in m/s.
Solution:
We know that,
Distance covered in 1 lap = 400 m
Distance covered in laps = 
m
= 
m
= 
m
We know that,
1 minute = 60 seconds
3 minutes = 180 seconds
3 minutes 45 second = 180 + 45 seconds
= 225 second
The speed of the athlete is:
Therefore, the speed of the athlete is about 8.44 m/s.
X = number of DVDs
1 DVD costs $1.95 to rent
x DVDs cost 1.95x dollars to rent
tack on the membership fee of 4.95 and the total cost is 1.95x+4.95
set this equal to 42 and solve for x
<span>1.95x+4.95 = 42
</span>1.95x+4.95-4.95 = 42<span>-4.95
</span>1.95x = 37.05
<span>1.95x/1.95 = 37.05/1.95
</span>x = 19
So Shanti can rent 19 DVDs
Answer:
p = -0.004n+34
Step-by-step explanation:
The slope of the linear equation can be found by using the two given points (30, 1000) and (22, 3000):
Applying the point (30, 1000) to the general form of a linear equation with m =-0.004, gives us the linear relationship between price (p) and number of shirts (n):
B.
X=5
7(5+9)=7•x+7•9
(7•5)+(7•9)=7x+63
35+63=7x+63
Subtract 63 from both sides and you will be left with
35=7x
Divide each side by 7 (you pretty much just divide 35 by 7)
And x=5
