A^2+b^2=c^2
Is the Pythagorean theorem
area of triangle formula = ½ × B × H
28in2 = ½ × B × (8)
28in2 = 4 × B
28 ÷ 4 = B
Therefore, length of base = 7 inches
i hope my solution helps :))
Because it says "not black" we would do white marbles
There are 15 white marbles and a total of 20
So the fraction of white marbles to total would be 15/20
Because the answer is wanted as a decimal divide 15 by 20
15/20=.75
There is a .75 chance that she will not draw a black marble
The 100 is 100 or 25×4 is hundred??
A for 8 hours of work its 144$
B a little more than 3 hours for 60$
Hope this helps
