Look at the tenth digit, which is 4. now look at the digit to the right on the tenth digit that's 5. so the rule is if the digit to the right of the place ur rounding to is 4 or less, u round down, if it's 5 or up, round up. so in this case since there's a 5 u round up. 8.5 is the answer.
8.45 rounded to the nearest tenth is: 8.6 because 5 is equal to 5

To find this, use the Pythagorean theorem; x=√55mm, and y=3mm (√55)²+3²=z² 55+9=z² 64=z² √64=z 8=z z=8mm The answer is C: 8mm

Which pitcher has a greater capacity, one that holds 2 gallons or one that holds 12 quarts? How do you know?
Answers
so convert 4 quarts=1 gallon convert to quarts 2 gallos=2 times 4 quarts=8 quarts
2 gallons=8 quarts 12>8 12 quarts is greated than 2 gallons or you could have converted to gallons
1 gallon is 4 quarts so just divide 12 by 4 and you get three. So the 12 quarts equals 3 gallons which is obviously bigger than 2.
Jessie is building a doghouse. For one side of the roof, she needs a board that is 7 3/4 feet long. She has a board that measure 9 1/12 feet. How much of the length does she need to cut from the board? Show your work and simply the fraction.
Answers
9 1/12 ft = 109/12 7 3/4 = 31/4 You need to give them the same denominator, so you'll need to multiply the top and bottom of 31/4 by three 109/12 - ((31*3)/(4*3))=x 109/12 - 93/12 = x (109-93)/12 = x 16/12 = x (16/4)/(12/4) = x 4/3 = x 4/3 = 1 1/3 Jessie needs to cut 1 1/3 feet off the board.
In scalene triangle abc angle b is 45 degrees, and angle c is 55 degrees.What is the order of the sides in length from longest to shortest
Answers
First, let's find angle A.
The angles of a triangle always add up to 180 degrees. A + B + C = 180 A + 45 + 55 = 180 A + 100 = 180 A = 80 degrees The longest side is always opposite the largest angle. Since A is the largest angle, the longest side is BC. The next largest angle is C, and the next longest side is AB. And the smallest angle B gives us the shortest side AC. Therefore, your answer would be BC, AB, AC.
