Answer:
64 cm²
Step-by-step explanation:
Suppose the original paper was x cm on a side. Then the original perimeter was 4x.
When the square is folded in half, two of the sides are now x/2, so the perimeter is ...
x + x/2 + x + x/2 = 3x
If 3x = 24 cm, then x = 8 cm.
The area of the original paper is ...
A = x² = (8 cm)² = 64 cm²
Answer:
The answer to your question is $ 23
Step-by-step explanation:
Data
Initial cost = $20
tip = 15 %
Total payment
Process
1.- Calculate the 15% of $20, considering that $20 is 100%.
$20 ---------------- 100 %
x ---------------- 15%
x = (15% x $20) / 100%
x = $300 / 100
x = $3
2.- Total payment
P = $20 + $3
P = $23
3.- Conclusion
Theresa payed $23 for the manicure
Here, d=20 km
t=1/2 h
s=?
Substitute all of 'em in the formula, s = 20/ 1/2 = 20*2/1 = 40
So, Car is travelling with speed of 40Km/h.
