Since she already owns one, and they are priced for 2 for a dollar. She would only need to spend $2 dollars to have for and then she will have 5 in total.
Switch a and f and see if that works
Answer:
4 ft
Step-by-step explanation:

A=10 h=5

20=5b (multiply both sides by 2)
4=b (divide by 5)
It is 70% Because:
250/100 + 175/x

Answer:
B. 50
Step-by-step explanation:
The alternate interior angles at transversal t across parallel lines AB and CD will be congruent.
2x +40 = x +90
x = 50 . . . . . . . . . . . subtract x+40
The value of x is 50.
_____
<em>Check</em>
2x+40 = 2×50 +40 = 140
x+90 = 50 +90 = 140 . . . . so the obtuse angles are congruent, as they should be
___
<em>Additional comment</em>
The lines AB and CD are not shown as being parallel. We have to assume they are, or we cannot work the problem.
