olga55 [171]

Answer:

length = 30 feet and width = 20 feet

Step-by-step explanation:

Let l is length and b is width of a rectangular yard. The area of a rectangle is given by :

A = lb ..(1)

A rectangular yard has a length that is 10 feet longer than the width.

length, l = 10+b ...(2)

ATQ,

Put the value of l in equation (1),

(10+b)b=600\\\\10b+b^2=600\\\\b^2+10b-600=0\\\\b^2+30b-20b-600=0\\\\b(b+30)-20(b+30)=0\\\\(b+30)(b-20)=0\\\\b=-30\ \text{feet}\ \text{and}\ b=20\ \text{feet}

Width can't be negative. The width is 20 feet.

Put the value of b is equation (2),

l = 10+20

l = 30 feet

Hence, the length and width are 30 feet and 20 feet.

Ft (full time)= $2,400/ monthpt (part time)= $200/ week15% taken from taxes------------------------- 1 year= 12 months; 1 month= 4 weeks (12*2,400) + (4*12*200)= $38,400 you made in a year I set up the problem this way because you want to know how much you made that whole year, so if there are 12 months in a year, and you get paid $2,400 a month, then from your full time job you ear (12*2,400). From your PT job you make $200 a week, there are 4 weeks in a month and 12 months in a year, so to calculate what you earned from your PT job, you do: 4*12*200 15% of what you made is deducted from taxes:0.15(38,400)= $5,760 After taxes, you made:$38,400-$5760= $32,640
