if the time is 8:50 and sally needs to go to a class at 10:30 how many hours and minutes will she need to put in a timer to remind her?

She can do 9:30 to 10:15!

Step-by-step explanation:

Helping out!

It is 8:50, 10 minutes before 9:00.

From 9:00 to 10:00 is 60 minutes, or one hour.

10:00 to 10:30 is 30 minutes.

So, take all of the minutes you figured out and add them.

10+60+30=100

One hour is 60 minutes, so if we subtract that from 100 minutes (100-60) we are left with 40 minutes.

Of course, this is an exact timing. If she wants to arrive 15 minutes earlier,

100-15=85

85-60=25

So, then she could put a timer for 1 hr 25 mins.

Therefore, Sally must put a timer for 1 hour and 40 minutes, if she wants the exact time of the class.

Hope this helps.

it would more likely be bald eagle because its has more in the box so about 75%.

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
