Answer:
40 ft × 75 ft
Step-by-step explanation:
Let x be the one side ( in feet ) of the rectangular parcel,
So, the diagonal between opposite corners = ( x + 10 ) feet,
Let y be the other side of the rectangle ( adjacent to side x ),
The area of the rectangle,
A = x × y,
According to the question,
A = 3000 square ft,
∵ In a rectangle,
Where, a and b are the adjacent side of the rectangle and D is the diagonal,
By graphing the equation,
We found that,
The only real zeros of the equation is at x = 75,
Hence, the one side of the rectangle = 75 ft,
And, second side = = 40 ft
Hence, the dimension of the land is 40 ft × 75 ft
Answer:
99 minutes, or an hour and 39 minutes.
Step-by-step explanation:
It takes Emma 18 minutes to do 14 pages. That means that we can set up a proportion, where Emma uses 18 minutes to do 14 pages, which is equal to x minutes per page!
14x = 18
7x = 9
x = 9/7
So, each page takes 9/7 minutes for Emma to finish.
She will do 77 pages. 77 * (9/7) = 11 * 9 = 99.
So, it will take Emma 99 minutes, or an hour and 39 minutes, to type and spell check 77 pages.
Hope this helps!
