" A car's fuel consumption is a measure of miles driven per gallon of gas. If you know the distance you drove and how many gallons fit in your tank, you can simply divide the miles by the gas to get your "miles per gallon," or mpg. You can perform the same calculation with kilometers and liters as well. The best time to record is right after you fill your car with gas. Newer cars have a trip odometer that you can set to zero at any time. It is usually on the dashboard or center console, with a small button you can hold to reset it to zero. Set it to zero when you fill up the car and check it when you need to fill up again -- this is your mileage since you last bought gas. Your trip odometer will say "0 miles." If you don't have a trip odometer, record the number of miles on your car as "Starting Mileage." For example, if your car has 10,000 miles on it when you fill your tank, write "10,000." Before you start filling up your car at the gas station, record the mileage on the odometer as "Final Mileage." If you do not have a trip odometer, subtract your "Starting Mileage" from your current mileage to find out how far your traveled. If your odometer now says 10,250 for example, subtract 10,000. You drove 250 miles on that tank of gas. You can perform this calculation no matter how much gas is left in the tank, but the more gas you use the more accurate your reading will be. Refill your tank completely and note how many gallons/liters you needed to fill the tank back up. This is you "Fuel Usage." You must refill your tank completely for this to work, otherwise you don't know how much gas your car used since your last tank. This tells you how many miles you drove per gallon of gas. For example, if you drove 335 miles before refueling, and you filled your car up with 12 gallons of gas, your fuel consumption was 27.9 miles per gallon, or mpg (335 miles / 12 gallon = 27.9 mpg). If you measured in kilometers and liters, you should instead divide fuel used by kilometers traveled and multiply the result by 100 to get "liters per 100 kilometers". You have to start from a full tank and return to a full tank to know exactly how much gas your car consumed. Terry's odometer reads 23,500 with a full tank. After driving for a few days he needs to buy gas. The odometer reads 23,889, and it takes 12.5 gallons to refill his tank. What was his fuel consumption? Fuel Consumption = (Final Mileage - Starting Mileage) / Fuel Usage Fuel Consumption = (23,889mi - 23,500mi) / 12.5 gallons Fuel Consumption = 389mi / 12.5 gallons Fuel Consumption = 31.1 mpg

One-sentence summary -- Know that the equation for fuel consumption is "Miles Driven divided by Amount of Gas Used. Reset the "trip odometer" after you fill up your tank. Record the miles on the trip odometer right before you buy more gas. Drive your car until the tank is almost empty. Record the amount of gas you buy in gallons. Divide mileage by fuel usage to see your car's fuel consumption. Practice calculating with an example.

Ryegrass is characterized by glossy leaves and clumpy flowers. And given the reflective ability of its surface, it has a distinctive shine that separates it from other types of grass. They also possess reddish-colored seedheads. Using chalk as a marker makes it easier to keep track of all the rye glass that needs removing. It can also be used to track new growth. You can also use your chalk to mark regions of removed ryegrass to track any new growth. Although ryegrass roots can reach up to 20 inches (51cm) deep, digging at this depth should sufficiently disrupt the root system. If you're having trouble digging, pour water onto the soil to soften it. This will prevent it from getting sunlight and prevent growth of ryegrass seeds in the soil. You can also use herbicide-infused fabric. Place heavy rocks or bricks onto the edges of the fabric to ensure that it is held down The best time to place herbicide-infused fabric is the summer. After removing your fabric, drag a thatch rake over the area to aerate it prior to planting any seeds. Use the same motion as you would with a standard rake, allowing the spokes to dig into the thatch. Pull it upwards to loosen and lift the thatch from your lawn. Keep an eye out for remaining seeds. Ryegrass seeds can germinate in 3 days. Remove all seeds that you find from the area.

One-sentence summary -- Locate the ryegrass you want to remove. Sprinkle white chalk powder on ryegrass to identify it. Use your spade to dig 2 inches (5.1cm) around the marked area. Cover your ryegrass regions with a landscaping fabric. Remove the fabric after 14 days and dig up the dead grass.

Whether you've hired someone to model for you or you're photographing a family member, think ahead about what you'd like your model to wear. Is this a dressy shoot, or a casual one? Keep in mind that people look best in pictures when they're comfortable in what they're wearing. Consider asking your model to be ready to change into several different outfits. If you're taking graduation photos of your daughter, for example, you may want to have pictures of her wearing her graduation dress, her favorite outfit, and her basketball uniform. Gather props to go with the different looks. Hair and makeup are also important components when it comes to creating a professional effect. Remember makeup doesn't show up as well in photos as it does in person, so you may want your model to wear a brighter shade of lipstick or a tad more eyeliner than normal.

Some people feel anxious or depressed around mid-life. Perhaps you feel sad about not accomplishing your goals or having a different life than you expected. You might also begin to feel anxious about the changes you experience physically and impending old age and death. Don't ignore your feelings or brush them off. Acknowledge how you feel and don't be afraid to get help. Identify symptoms of depression and anxiety and get help if you need it. Consider keeping a journal, or an autobiography of sorts. Writing your thoughts, feelings, and experiences can help you reflect on the kind of life you've led and the kind of life you want. Keeping a journal can also help you maintain perspective and see situations and events from multiple standpoints. Writing about your life can help you gain some perspective about your choices and what you've learned from them. Even if your life isn't what you wished it was, you can reflect on all the ways you've grown as result of your experiences. Choose a therapist who will help you move through the process of your crisis, not end it as quickly as possible. Work toward a rediscovery of who you are and what you want. Be open and honest and allow yourself to express your thoughts and emotions while in therapy. Find a therapist by contacting your insurance provider or a local mental health clinic. You can also ask for a recommendation from a physician, friend, or family member.
