A​ landscaper, who just completed a rectangular flower garden measuring 15 feet in length by 7 feet in​ width, orders 1 cubic ya
grin007 [14]

The width of the border will be 0.1648... ft  or  1.9786... inches.

<u><em>Explanation</em></u>

Lets assume, the width of the border is  x ft.

The rectangular garden is 15 ft in length and 7 ft in width. So, the area of the garden =(15*7)ft^2= 105 ft^2

Now, the length of the garden including border =(15+2x) ft and the width of the garden including border =(7+2x) ft

So, the area of the garden including the border = (15+2x)(7+2x) ft^2

Thus the area of the border =[(15+2x)(7+2x)-105] ft^2

Total amount of premixed cement needed is  1 yard³ = 27 ft³

As the depth of the border is 44 inches or (\frac{44}{12})ft or (\frac{11}{3})ft, so....

\frac{11}{3}[(15+2x)(7+2x)-105] = 27\\ \\ 11(105+44x+4x^2 -105)=81\\ \\ 11(4x^2+44x)=81\\ \\ 44x^2+484x-81=0

Using quadratic formula....

x= \frac{-484+/-\sqrt{484^2-4(44)(-81)}}{2(44)}\\ \\ x= \frac{-484+/-\sqrt{234256+14256}}{88}\\ \\ x= \frac{-484+/-\sqrt{248512} }{88}\\ \\ x= 0.1648...

<u>(Negative value ignored)</u>

So, the width of the border =0.1648...ft= (0.1648...*12)inches= 1.9786...inches

vertex (-3 , 7)

Step-by-step explanation:

vertex (h, k)     f(x) = a | x - h | + k

f(x) = |x + 3|+ 7 ,    h = - 3 and k = 7

vertex (-3 , 7)

Math triangle fun please help!
IgorC [24]

Answer:

Step-by-step explanation:

You can use the cosine rule to solve this problem:

cos(∠KLJ) = (KL² + JL² - KJ²)/(2*JL*KL) = 21463/21960 = 0.97737

∠KLJ = cos⁻¹(0.97737) = 12.2°
