Ali's tyre pressure gauge shows a reading which is 8% lower than the actual pressure.
What is the actual pressure of Ali's tyres when the gauge shows 33.58?
33.58 / (1 - .08)
=36.5
36.5 is coorect
correct*
idk lol
36.5 is the correct answer
To find the actual pressure of Ali's tires when the gauge shows 33.58, you need to account for the 8% lower reading.
Step 1: Calculate the actual pressure:
Let x be the actual pressure of Ali's tires. Since the gauge reading is 8% lower than the actual pressure, the gauge reading can be expressed as 0.92x (100% - 8% = 92%).
Step 2: Set up an equation:
Since the gauge reading is 33.58, we can set up the equation:
0.92x = 33.58
Step 3: Solve for x:
To find x, divide both sides of the equation by 0.92:
x = 33.58 / 0.92
Step 4: Calculate the actual pressure:
Use a calculator to solve the equation:
x = 36.5
Therefore, the actual pressure of Ali's tires when the gauge shows 33.58 is 36.5.
