Answer:
$28.82
Step-by-step explanation:
Since we are adding a 13% tax, we multiply 25.50 by 1 plus .13:
25.50(1 + 0.13)
25.50(1.013)
28.815
Alternatively, we could multiply 25.50 by 0.13 and then add the results:
25.50(0.13) = 3.315
25.50 + 3.315 = 28.815
Answer:
16
Step-by-step explanation:
If each game is $1.50 we would divide the 24 by 1.50, or multiple 1.50 to find 24. So 24 divided by 1.50 is 16.
So she could play 16 games.
Answer:
- a = 65°
- b = 25°
- c = 25°
- d = 75°
Step-by-step explanation:
The sum of angles that make up a linear angle is 180°, so we have ...
60 + a + 55 = 180
a = 65 . . . . . . . . . . . . . . subtract 115
The acute angles in a right triangle are complementary, so we have ...
b = 90 -65 = 25
Vertical angles are congruent, so ...
c = b = 25
___
Angle d is the complement of the one marked 15, so its measure is ...
d = 90 -15 = 75
The angle measures are ...
a = 65°
b = 25°
c = 25°
d = 75°
