Answer: They would have to score an 88%
Step-by-step explanation:
1.) The mean of 84, 92, 83, and 78 is 337
2.) 337 divided by 4 is 84.25%
3.) If you add 88 to 337 and divide by 5, you get 85%
7\24 or 7\8 if you add it together or just add the numerator
The rule associated with moving decimal places, and multiplying by a value or multiple of 10, would be the following :
If you divide a value by 10 or a multiple of 10, you would move the decimal place to the left number of times as there are zeros in the multiple.
(Assuming that there are no zeros in the numerator value)
If you multiply by 10 multiple, then you would move the decimal to the right that many times as there are 0's in the value.
The solution would be that the decimal number is multiplied by 100.
Answer:
A. $46,650
Step-by-step explanation:
Taking the first number of $50,150, we have to subtract his expenses. After subtracting Leroy's expenses, we get $46,650.

Answer: 20 feet
Step-by-step explanation:
This represents a right angled triangle with the length of the slide being the hypotenuse, the height of the ladder being the height of the triangle and the distance from the base of the ladder being the length.
Solve with Pythagoras rule:
c² = a² + b²
c = hypotenuse
a= length
b = height
29² = 21² + b²
841 = 441 + b²
b² = 841 - 441
b² = 400
b = √400
b = 20 feet
