T=total cost m=number of movies t=1.99m+5.50. I hope this helped.
Answer:
by solving the divisions
Step-by-step explanation:
- 8/9 ÷ 7/11 = 8/9 × 11/7 = 88/63 = 1.40
- 19/12 ÷ 3/10 = 19/12 × 10/3 =190/36 = 5.28
- 19/12 ÷ 1/15 = 19/12 × 15 = 285/12 = 23.75
8/9 ÷ 3/10 = 8/9 × 10/3 = 80/27 = 2.96.
now from the solutions you can get the least to greatest
1.40 , 2.96, 5.28 and 23.75
After getting answer in decimal form change it to fraction like how they set the question
Answer:
Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=
r

mv

=
r

mu

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

=

u

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
Answer:
B
Step-by-step explanation:
It is B because every number, x, you plug in 5x-3, it is y.
