A bike tire just ran over a nail, and it is losing pressure at a rate of 5% every minute. The tire pressure is currently 490 kilopascals. What will it be in 3 minutes

420.11 kilo-pascals.

Step-by-step explanation:

We have been given that a bike tire just ran over a nail, and it is losing pressure at a rate of 5% every minute. The tire pressure is currently 490 kilo-pascals. We are asked to find the tire pressure in 3 minutes.

We will use exponential decay formula to solve our given problem.

, where,

y = Final value,

a = Initial value,

r = Decay rate in decimal form,

x = Time.

Let us convert 5% into decimal.

Initial value is 490. Upon substituting our given values in above formula, we will get:

To find tire pressure in 3 minutes, we will substitute and solve for y as:

Therefore, the tire pressure will be approximately 420.11 kilo-pascals in 3 minutes.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
