Step-by-step explanation:
1984: 8855
1983: 8855*10/100=885.5
8855-885.5
7969.5
1982
7969.5*15/100=1195.425
7969.5-1195.425
6774.075

Find the length of the hose = 5.2 feet
Step-by-step explanation:
The garden is divided into two similar triangle.
The hose divided one side of the triangle to two equal parts.
Side a = 6ft
Side b = 3ft
Side c = ? (length of hose)
a² = b² + c²
6² = 3² + c²
36 = 9 + c²
27 = c²
√27 = c
5.196 = c

Answer:
B
Step-by-step explanation:
First, let's rearrange the given equation into something more recognizable. If we add 13 to both sides, we now have the polynomial
. We can now use the quadratic formula to solve.
Remember that the quadratic formula is

Substitute the numbers from the equation into the formula.

Simplify:


Here, I'm going to assume that there was a mistype in option B because if we divide out the 2 we end up with
.
Hope this helps!
