Answer:
Weight of mixing water=224.541 lb
Step-by-step explanation:
Taking 1 cubic yard of concrete
Mass of gravel = 2314 lb
Moisture content = 3.5% Absorption 4.2%
Extra water needed = (4.2-3.5)*2314/100= 16.198 lb
Mass of sand= 899 lb
Moisture content = 5.7% Absorption =1.4%
Water released = (5.7-1.4)*899/100= 38.657 lb
Free water = 244 lb
Weight of mixing water = free water + extra water needed-water released = 244+16.198-38.657=224.541 lb
Weight of mixing water=224.541 lb
Select the correct choice below and, if necessary, fill in the answer box within your choice.

Step-by-step explanation:
B. the height of a dog in inches and the number of ounces of food the dog eats per day
C. the number of sit-ups completed and the number of calories burned during a workout
D. the time spent reading a book and the number of pages remaining to be read in the book
The pair of variables that will most likely have a negative correlation are D. the time spent reading a book and the number of pages remaining to be read in the book.
If you spend a longer time reading a book, you would read more pages which would reduce the number of pages left to be read. The time taken to read the book is therefore negatively correlated with the number of pages left.
In conclusion, option D is correct.

Answer: D
Step-by-step explanation:
The area of the stop sign which is an octagon is 744 square inches.
Option C is the correct answer.
We have,
To find the area of the stop sign, we can use the formula for the area of a regular polygon:
Area = (1/2) × perimeter × apothem
The perimeter of the stop sign is 8 × 12.4 = 99.2 inches.
Using the given apothem of 15 inches, we can plug in the values and calculate:
Area = (1/2) × 99.2 × 15
Area = 744 square inches
Therefore,
The area of the stop sign is 744 square inches.
