Answer:

Height = 3.82

Step-by-step explanation:

(3.14)(5)²

(3.14)(25)

= 78.5

300 = 78.5h

300/78.5 = 78.5h/78.5

h = 3.821656051 or approximately 3.82

Solve 9x^2- 17x- 85 = 0 Give your solutions correct to 3 significant figures.

dybincka [34]

Answer:

$x =\frac{17}{18} +\frac{1}{18} \sqrt{3349}$ OR $x =\frac{17}{18} +\frac{-1}{18} \sqrt{3349}$

Step-by-step explanation:

9x2−17x−85=0

For this equation: a=9, b=-17, c=-85

9x2+−17x+−85=0

Step 1: Use quadratic formula with a=9, b=-17, c=-85.

$x =\frac{-b + \sqrt{b^{2}-4ac } }{2a}$

$x =\frac{-(-17)+\sqrt{(-17)^{2} -4(9)(-85)} }{2(9)}$

$x =\frac{17}{18} +\frac{-1}{18} \sqrt{3349}$

True [87]

Step-by-step explanation:

we have

length =8in

breadth =6in

since . The length and width of the actual flower bed will be 24 times larger than the length and width in the drawing.

new

length=8×24=192in

breadth =6×24=144in

(b) What is the perimeter of the actual flower bed ? Show your work.

answer:the perimeter of the actual flower bed =2(l+b)

 =2(l+b)=2(192+144)=672in

(a) What is the perimeter of the drawing? Show your work

answer : the perimeter of the drawing

=2(8+6)=96in

(c) What is the effect on the perimeter of the flower bed with the dimensions are multiplied by 24? Show your work

perimeter of flower bed /perimeter of drawing

=96/672=1/7

<h3>perimeter of drawing is increased by 7times of perimeter of flower bed</h3>
