Answer:
100
Step-by-step explanation:
Original price: x
x + (7%*x) = 107.
107 is 107% of the original price
107 = 1.07x
Divide by 1.07 on both sides
x = 100
Check:
7% of 100 is 7
100 + 7 = 107
Hope this helps :)
Answer:
18.02 cm
Step-by-step explanation:
A diagonal makes a rectangle into two right triangles. So if we use the Pythagorean theorem we can find the hypotenuse which is the diagonals.
Remember, because we know the length and width, we know the two sides.
10^2 + 15^2 = c^2
100+225 = c^2
325 = c^2
18.027 ≈ c
