Answer:
Yes, Mark has $16 left and only has to pay his sister $15.
Step-by-step explanation:
1/5=x/20
use cross multiplication to find (x),which represents 20% of 20.
x/20=1/5 (cross multiply)
20=5x (divide by 5 on both sides)
x=4
This tells you that Mark gave $4 to the local charity.
20-4=16
Subtracting 4 from his original amount, he now has $16 left.
Hello from MrBillDoesMath!
Answer: Choice b
Discussion:
Look for corresponding parts in each figure. In this case, the we find
10/ 8 is the ratio of the heights
and
425/x is the ratio of the widths
So 10/8 = 425/x which is choice b.
Thank you,
MrB
Answer:
Midpoint = (10,6)
Step-by-step explanation:
Using Coordinates: X(6,5) and Y(14,7)
Using the midpoint formula: M = (X1 +Y1)/2, (X2 + Y2)/2
Midpoint of XY = (6 + 14) / 2, (5 + 7) / 2
Midpoint of XY = (20) / 2, (12) / 2
Therefore the midpoint of XY is (10,6)

Answer:
15 m
Step-by-step explanation:
you would use a sin equation because given the angle, the side you are resting to find is Opposite and the side you are given is the Hypotenuse
sin (32) = a/28
28 x sin (32) = a
14.83 = a
15 m = a when rounded
