Step-by-step explanation:
The area of a square is

where s is the side length.
It is given that the smaller square side length is s so that means the area of that smaller square is the formula above.
The longer square is twice the side length of the side length of the smaller square.
Since all squares have equal sides, that means all the side are twice than the smaller square sides.
We can represent that larger square area by
(4s) squared
To find how many smaller squares it would take to fill the larger square divide the formula by each other.
(4s)÷s squared =4
This is how you do it hope this helps.
Hi There!
Follow y = mx + b
m = slope
b = y intercept
(a) What are the slope and the y-intercept for the equation that represents the number of baskets of berries the workers picked over a period of time?
Slope = 5
Y intercept = 10
(b) What are the rate of change and the initial amount? Explain the meaning of the rate of change and the initial amount for the situation.
The rate of change is how much it takes for the amoun to change. The initial amount should be going up with a slope of 5 each time.
(c) Use graph paper to draw a graph representing the situation. Label the axes appropriately.
Start at the origin than continue with a slope of 5 and make sure the y intercept is correctly graphed.
Answer:
$14
Step-by-step explanation:
The revenue from sales of fans is the product of the number of fans sold and the price at which they are sold:
R(p) = n·p = (1960-70p)p
R(p) = 70(28 -p)p
This equation describes a parabola that opens downward and has zeros at p=0 and p=28. The axis of symmetry is halfway between those zeros, at p=14. It goes through the vertex or point of maximum revenue.
The price for maximum revenue is p = 14 dollars.
