Using proportions, it is found that the total amount of cement, sand, and gavel required is of 55.2 cubic yards.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
The decimal equivalent to the mixed number 1 1/2 is given by:
1 + 1/2 = 1 + 0.5 = 1.5.
1.5 times 36.8 cubic yards is:
1.5 x 36.8 = 55.2.
The total amount of cement, sand, and gavel required is of 55.2 cubic yards.

Answer: 5:50
Step-by-step explanation:
20+15+5=40. 6:30 minus 40 min is 5:50
Answer:
It has to be 145 degrees.
Step-by-step explanation:
There would be 2 60's and one 95. 360-95-(60*2)=145.
Answer:
a=-4000m+39000
Step-by-step explanation:
From the given table, we can see that the difference between any consecutive altitude is 4000 ft.
31000 - 35000 = -4000
27000- 31000 = -4000
23000-27000 = -4000
Hence, it represents an arithmetic sequence with a = 3500 and d = -4000
The general term of an arithmetic sequence is given by
The correct answer is (A)!
