2.50x=90
X stands for the number of times he can ride the bus.
To solve this, you'd take 90/2.5 which is equivalent to 36. He would be able to ride the bus 36 times.
OQ = 8 + 9 = 17
x^2 = 17^2 - 8^2
x^2 = 289 - 64
x^2 = 225
x = 15

A. Area of given figure = 280 + 77 = 357 cm²
B. length of semicircle = 22 cm
The answer is 4.1
If the number is below 5, you round down, if it's 5 or above, you round up.
