Since you know that interior angles of one transversal add up to 180, we can subtract 72 from 180 to solve for angle DAB. 180-72=108. Our answer is angle DAB=108°
15) 25+90=115-180=65
65+90=155-180
Step-by-step explanation:
she increased the amount from 48g to 54g. that is 54-48 = 6g.
so, the question really is, how many % of 48 is 6 ?
100% = 48g
1% = 100%/100 = 48/100 = 0.48g
how many % are 6g ?
as many as how often 1% (0.48g) fits into 6g :
6 / 0.48 = 12.5%
Answer:
$64.93
Step-by-step explanation:
All you have to do is multiply the amount of money by the percent (in this case, the decimal of 0.2):
324.65*0.2 = 64.93
Let width = x ft then
2x + 2(2x) = 42
6x = 42
x = 7
so the width is 7 ft and length is 14 ft.
So the cost to build the pen = 14*1.25 + 14*1,25 + 7*2.50 + 7*2.50
= 70 answer
