W= -0.5m + 16henry's water bottle is leaking at a constant rate. the amount of water, w in ounces, that is left in the water bottle after leaking for m minutes is given by the equation above. what does the −0.5 mean in the equation? the water bottle loses 2 ounces of water per minute the water bottle loses 0.5 an ounce of water per minute the water bottle has 0.5 an ounce of water in it at the start 0.5 of the water has leaked from the water bottls in one minute

• The water bottle loses 0.5 an ounce of water per minute

Step-by-step explanation:

The definition of the variables tells you that m stands for minutes and that W stands for the water remaining in the bottle. So, the -0.5m in the equation has the effect of reducing the remaining water by 0.5 each time m increases by 1. That is, there are 0.5 fewer ounces of water after each additional minute: the bottle loses 0.5 ounces per minute.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
