To avoid a storm, a passenger-jet pilot descended 0.44 mile in 0.8 minutes. What was the planes average change of altitude per m

Tcecarenko [31]

The average change of altitude per minute would simply be the ratio of distance descended over time. That is:

average change of altitude = distance / time

average change of altitude = 0.44 mile / 0.8 minutes

<span>average change of altitude = 0.55 mile / minute</span>

There are 25 students in Mrs. Venetozzi’s class at the beginning of the school year, and the average number of siblings for each

andrezito [222]

Adding the student with eight siblings will increase the class average amount of siblings because this student has more siblings than the average.

Therefore, the average number of siblings that each student has is larger than the original average.

Fine the equation of the line that is perpendicular to the given line and passes through the given point. Enter the right side o

Kipish [7]

Answer:

$y=-\frac{4}{7} x+\frac{55}{7}$

Step-by-step explanation:

Change the given equation to slope-intercept to get $y=\frac{7}{4}x-\frac{1}{4}$ . When you multiply the slopes of perpendicular lines, you get -1. -1 divided by $\frac{7}{4}$ is $-\frac{4}{7}$ . The slope of the new line is then $-\frac{4}{7}$ . The perpendicular line passes through (5, 5) so you can have the equation $5=-\frac{4}{7} (5)+b$ . Simplifying gets $b = \frac{55}{7}$ . So now the final equation for the perpendicular line is $y=-\frac{4}{7} x+\frac{55}{7}$

Is 4.15 greater than 4.051

I am Lyosha [343]

Yes (my answer need to be greater than 20 characters long so...Ahhhhh). A way to help you is see it as 4.1 and 4.0 because the # after the 1 aren't that important

I need help Im not too good Solving Problems Involving get Unig Rate.

ira [324]

To find unit rate, it's typically done with the equation (y/X). in this case X=minutes and y=laps. so plug the numbers into the equation.(81/27). whatever the answers is, that's your constant of proportionality, or unit rate. multiply your unit rate with the minutes and divide the laps by the unit rate to find the minutes.

minutes=m
laps=l
unit rate=k

m×k=l
l/k=m
