Answer:
3 metres
Step-by-step explanation:
Let the width of the pathway be x
Area: (9+2x)(4+2x)
36 + 8x + 18x + 4x²
4x² + 26x + 36
Increased area is 150:
4x² + 26x + 36 = 150
4x² + 26x - 114 = 0
2x² + 13x - 57 = 0
2x² + 19x - 6x - 57 = 0
x(2x + 19) - 3(2x + 19) = 0
(x - 3)(2x + 19) = 0
x = 3, x = -19/2
Answer:
12.8 cm
Step-by-step explanation:
Radius of the can is 8 cm and height is 20 cm.
It is given that after painting his porch Jamil has of a can of paint remaining. So, first we need to find the total amount of paint in the can.
Total amount of paint in the can is
So, paint in the can
Now of the can is
cubic cm.
Now, let the height of the smaller can be <em>h</em> cm.
Radius of the smaller can is 5 cm.
As, the paint is poured into the smaller can the volume of both the cans will be same.
Hence, height of the smaller can to hold the paint must be 12.8 cm.
Answer:
Step-by-step explanation:
I think the question below is the one you wanted to ask:
<em>A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 6 centimeters per minute. After 20 minutes, the water level is 220 centimeters
</em>
<em>Graph the pool's water level (in centimeters) as a function of time (in minutes).</em>
Here is my answer:
To draw the linear line, we need to identify the equation that modles this situation. As we know the water level rises at a rate of 6 cm per minute which mean the slope m = 6
The standard form is: y = mx + b <=> y = 6x + b
After 20min the water level is 220 cm
<=> 220 = 6(20) +b
<=> b = 100
So your equation is : y = 6x + 100 and the initial amount of water in it is 100
