Answer:
760 feet
Step-by-step explanation:
Area of the parallelogram = base times height
So 40 times 38 = 1520 feet
Area of rectangular walkway = 38 times 20 = 760
1520-760=760
Answer: 1520 square feet
Step-by-step explanation: Find the area of the triangle on the right. The bases are 38 and 40. Use the formula 1/2(l*w). 38*40=1520. 1520/2=760.
Next find the area of the triangle on the left. Since it's a parallelogram, both the top and bottom will be the same, so the other base is 40 ft. This also means that the area will be the same, so its area is also 760.
Finally add up the areas of the two triangles. 760+760=1520.
Answer:
6.4
Step-by-step explanation:
all you have to do is divide 16/2.5 (2 1/2) and you get 6.4
hope this helped!!
After 50 minutes, the pool has 73.74% of its initial water left, meaning it drained 26.26% of the initial water. To represent this remaining amount in gallons, it would be 0.7324 times the initial volume (in gallons).
To answer your question regarding the amount of water left after draining the pool for 50 minutes with a drain rate of 3% every five minutes, it is important to understand that the reduction occurs in a compound manner. This means each time we are dealing with 97% (100% - 3%) of the previous total.
So after 10 iterations (equaling to your 50 minutes since each iteration is 5 minutes long), we are left with (0.97)^10 = 73.74% of the initial total. That means 26.26% of the water has been drained.
In terms of gallons, if X represents the initial volume of water in the pool, then 0.7324 * X gallons remain after 50 minutes. Without knowing the initial volume of the pool, it is impossible to give a precise value in gallons.
