A 2 pound box of salt sells for $.89 and a 5 pound box sells for 2.09. What is the linear equation for this?
castortr0y [4]
Y = ax + b;

0.89 = a * 2 + b and 2.09 = a * 5 + b =>
=> 2.09 - 0.89 = a * 5 + a * 2 + b - b => 1.20 = 3 * a => a = 1.20 / 3 => a = 0.40;
b = 0.89 - 0.40 * 2 => b = 0.89 - 0.80 => b = 0.09;

y = 0.40x + 0.09 => 0.40x - y + 0.09 = 0 is the linear equation.

Find the area, correct to the nearest square
Lady bird [3.3K]

Answer:

1269 square meters

Step-by-step explanation:

The path and the plot of land form two concentric circles (they have the same center). The radius of the plot of land is 100m (half of the diameter) and the radius of the larger circle, formed by putting a 2m wide path around the plot of land, is 102m. Thus, the area of the path is \pi *102^2 minus \pi *100^2 which will be 10404\pi-10000\pi which is 404\pi. Estimate \pi to 3.141 and calculate, getting 1268.964... which is 1269, rounded to the nearest square meter.

Hope this helps :)

I need to know if 3750 is right or wrong cause I think that’s the answer
brilliants [131]
It’s wrong.

The surface area means the area of the outside of the cube.

The area of a square is just width x height. And we are told one of the sides is 5.

A square has all equal sides. So what’s 5x5? then times that by the number of squares

I’ll put the answer in the comments
