Sand to cement
7:3
210:x
ask yourself what number is needed to multiply by 7 to get 210 ( so you'd divide 210 by 7 which is 30). Multiply the other side by thirty as well to get the value of x
3*30 which is 90

Answer:
25. 
26. 
Step-by-step explanation:
For 25:
(area of a trapezoid)
(substitute terms)
(collect like terms)
(reduce the fraction by crossing out 2)
(calculate)
For 26:
(equation of area of a circle)
(enter the radius)
(communtative property to reorder the terms)
Answer:
It is a trinomal because there is 3 terms
It is a quadratic because the highest degree is x^2
All in all, It is a Quadratic Trinomal
Step-by-step explanation:
the ball reaches its maximum height of 15 feet in 2.2 seconds
The ball starts on the ground and travels in a parabolic shape as it reaches a maximum height and then returns to the ground
The ball starts on the ground at 0 seconds so the ball starts at x=0 seconds
the ball reaches its maximum height of 15 feet in 2.2 seconds
So it takes 2.2 second to reach the maximum height
It will take another 2.2 seconds to reach the ground
The time the ball in the air is 2.2 + 2.2 = 4.4
The ball will reach the ground in 4.4 seconds
So the domain for g(x) is {0,4.4}
