Step-by-step explanation:
Set up a proportion where x is the height of the tree:
= 
Cross multiply and solve for x:
5x = 80
x = 16
So, the tree is 16 feet tall
To find the number of words she can read per minute, we would do 560 divide by 7 minutes
560/7 = 80 words per minute
Hope this helps
60%; Since 1/5 is .2 or 20% and then multiply that by 3.
well, a and d are true, and b is somewhat false...
angles that are both less than 90 degrees and higher than 0 have to add up to equal 90, not just be less than 90
c, is the same thing. Straight angles are 180 degrees, but supplementary means two angles add up to equal 180 degrees, not just one
so b and c may be true, im not sure
i know that a and d are true, therefore they are not the right answer
