Answer:
65m+25=c
Step-by-step explanation:
So basically you just have to count how many numbers there are, so there are 3 91’s so you would put a 3 in the box go 91 and there’s only 1 57 so you put a 1 in the box.
Hey there! :)
Answer:
≈ $41330
Step-by-step explanation:
Begin by finding the area of the racetrack by subtracting the area of the smaller circle from the larger one.
Calculate the areas of the circles using: A = πr²
Larger circle:
A = π145²
A = 21025π = 66018.5 ft²
Smaller circle:
A = π80²
A = 6400π = 20096 ft²
Subtract the smaller from the larger of the areas:
66018.5 - 20096 = 45922.5 ft²
Divide this by 100 to solve for the amount of asphalt needed:
45922.5 / 100 = 459.225.
Since asphalt costs $90 dollars per 100 ft², then:
459.225 · 90 = $ 41330.25 ≈ $41330 rounded.
Remember order of operations. Please (Parenthesis and brackets) Excuse (exponents) My (multiplication) Dear (Division) Aunt (Add) Sally (Subtract). Also remember that multiplication and division as well as addition and subtraction should go from left to right. So if you were to do this problem first I'd convert the fraction 1/10 to a decimal. That's like saying 1 in 10 or 10%. So it should convert to .10 x 6 = 0.60 and don't forget to multiple 7 x1000 next. (Left to right). 7,000. So it becomes 5+10+0.60+7,000 then add. 7,015.60 is your answer.
