7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
From given question,
252 lb = 36 ft² ..........(1)
The number of pound for an area of 1 square foot is calculated as follows:
x = 1 ft² .......(2)
The area and the amount of gravel are illustrations of proportions.
From (1) and (2) we get an equation,
⇒ x × 36 = 252 × 1
⇒ x = 252/36
⇒ x = 7 lb
We need to find the area that could be covered with 315 lb of gravel
The area to be covered with 315 lb gravel is calculated as follows:
315 lb = y ............(3)
From (1) and (3) we get an equation,
⇒ y × 252 = 36 × 315
⇒ y = 45 ft²
Therefore, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

Answer:
(4x^2 + 3)(x + 3)
Step-by-step explanation:
Split the equation in the middle so you can factor it out:
4x^3 + 12x^2 | + 3x + 9
Then factor out:
4x^2(x + 3) | 3(x + 3)
Congrats, you completed your equation:
(4x^2 + 3)(x + 3)
Give more detail please this makes zero sense
Answer:
0.0625 kg per bag
or 1/16th of a kilogram per bag
Step-by-step explanation:
You'd need to divide the total amount the the number of sections.
In this case, it'd be 0.5 kg/8 bags, resulting in 0.0625 kg of flour per bag.
I hope this helps!
Answer:
Slope form of line y = 9
Step-by-step explanation:
m= 3
The y-intercept of the line that passes through the given point (0,9) is
9 = 3(0) + b
b= 9
The equation of the line that passes through the given point (0,9) is
y =mx +b
y = 0 +9
y=9
