As they are similar corresponding sides are in the same ratio, so
18/15 = x / 4
x = 4*18 / 15
x = 4.8 answer
To calculate the volume of a prism you multiply the area of it's cross section by the length
Therefore
5 x 3= 15
(Area of the rectangle)
15x8= 120
(Volume of prism)
R(s + t) = st
Rs + Rt = st
Rs - st = -Rt
s ( R - t) = -Rt
*s = - Rt / (R - t) Multiply through by -1 on the right.
*s = Rt / (t - R) Put in the brackets in your answer. What you have been writing means
s = Rt/r - R you need the brackets. The stars mean that either could be an answer. I think your problem could be the brackets. Now I'm reasonably certain this is correct.
Dist. travelled for the first 2 days
= 22 + 28
= 50
Dist. travelled for the remaining 83 days
= 1378 - 50
= 1328
Dist. travelled for EACH of the 83 days
= 1328 ÷ 83
= 16
Answer:
8 hours
Step-by-step explanation:
Let t hours be the time needed Sonya to catch up Brianna.
Sonya:
Time = t hours
Rate = 44.8 mph
Distance 
miles
Brianna
Time 
hours
Rate = 32 mph
Distance 
miles
Note that 
because Sonya must catch up Brianna.
Use formula 
Hence,
Solve this equation:
