Answer:
For 11, x=18
Step-by-step explanation:
Use a ratio to solve for x since the triangles are similar
16/20=(16+12)/(20+x-3), first simplify both sides
4/5=28/(17+x), cross multiply
4(17+x)=5*28
17+x=5*7
x=35-16
x=18
Answer:
Step-by-step explanation:
<u>The equation for the speed is:</u>
From the equation we see for the same t the speed is greater if d is greater.
We can show that if add a vertical line to a graph and compare the d- values of the intersection of the vertical line with the graphs of the cars.
It obvious the graph of the Car B will have a greater d- value.
It means that Car B has a greater speed so it is faster that Car A.
The correct answer is 18696 ft/hour
If you are asking the place value it is thousand. if you are asking about it all it is, 7 thousand 8 hundred 54 and 2 hundred 9 thousanths.
