Answer:
Maggie typed at a slower rate.
Step-by-step explanation: Maggie typed slower because 32 words/65 seconds is .49 words per second or half a word per second whereas Hector is 25 words/45 seconds or .55 words per second.
Answer: <u>110 feet per second</u>
Step-by-step explanation:
In this problem we will assume that the car at 45 miles per hour is moving into the x direction with a high of 100 feet, and the train is going in the y direction, so they trajectories will made an angle of 90º.
Now we can calculate the speed of the trains in feet per second so:


So we can make a right triangle with sides 66 and 88 and the hypotenuse will be the rate that the trains will separate per second so:


Is important to have in mind that the initial high is not going to change how fast the trains will separate, however, if we are going to calculate the distance we should have it in the calculations.
1/64 & 16
hope that helped :)
We can set this up as a proportion.
Since 2 is proportional to 1000, then 4 is proportional to "doctors surveyed".

where d is the doctors surveyed.
Cross multiply.
2d = 4000
d=2000
2000 doctors were surveyed.
calculate rise over run = 37 ÷ 63
