Answer:How many miles can a car be driven in 3 hours at 50 miles per hour? Under normal circumstances and the generally assumed conditions, the answer is of course (3 hours) * (50 miles / hour) = 150 miles.
3.5 hours
It will take you 3.5 hours to go 280 miles at 80 miles an hour.It travels at constant speed for the remaining time. Let x be the time traveled at the unknown constant speed. The total itme for the trip was 6 hours so: 6 = time traveled at 50 mph + time traveled at 60 mph + time traveled at x mph.
Step-by-step explanation:So you drive 25 miles / hour. then 25 miles/ 1 hour = 225 miles / nb of hours.2 minutes
However, traveling at 30 MPH for 1 mile (1 lap) takes 2 minutes, which means that your average will never be 60MPH.approximately 0.6818 miles per hour.
Answer: 21 cm
Explanation: it doesn’t make sense if the missing side was 45 cm because it’s shorter than the other sides and their measurements are 34 and 28 cm
See below for the response to each question
<h3>The variable</h3>
This is the item that is being surveyed.
The surveyed item is birth weights
Hence, the variable is birth weights
<h3>The
units of the variable</h3>
From the question, we have:
Average birth weight is 6 pounds 8 ounces.
Hence, the units of the variable are pounds and ounces
<h3>The population</h3>
This is the total number of babies in Southeast Asia
Hence, the population of interest is the babies in Southeast Asia
<h3>The individual</h3>
This is the people in the survey
Hence, the individual in the study is the 100 babies that were randomly surveyed
<h3>The
parameter of interest</h3>
This is the value that gives the required information.
Hence, the parameter of interest is the average birth weight
<h3>What is the statistic involved</h3>
The statistic is the average

#SPJ1
Answer:
7
Step-by-step explanation:
evaluate the function means substitute x=-1 and calculate
f(x) = 3x²-4x
f(-1) =f(x=-1) = 3(-1)²-4(-1) =3+4 =7, because (-1)²=1 and -4(-1) =4
Here's what we know:
4t = 7/10 (4 tasks take 7/10 of an hour)
Divide both sides by 4:
4t / 4 = 7/10 / 4
t = 7/40
So each task is 7/40 of an hour
7/40 n = 1 (Now we want to find the number of tasks completed in 1 hour)
Multiply both sides by 40/7:
n = 40/7
Converting improper fraction to a mixed number:
n = 5 5/7
So the robot will complete 5 5/7 tasks in an hour. If the answer is looking for fully finished tasks and not partially done ones, the you need to round down to 5.
