70%Step-by-step explanation:First, determine how many fixtures are left to install.270-81=189. The fraction representing the work still to be done is the count of fixtures to install divided by the total amount. So, % of work remaining equals 189 divided by 270, which equals 0.7. Converting this to percentage form gives us 0.7 * 100% = 70%.

How would you shade a model to show ten thousandths?
Zina [12379]
It’s challenging to demonstrate that on here unless I sketch a diagram for you... It’s important to recognize that 10 thousandths equates to 1 hundredth. If you draw a square measuring 100 by 100 centimeters on graph paper, it will include a thousand individual squares because 100 x 100 equals 1000, and if you shade 10 of those squares, that represents 10 thousandths.

What are the solutions of the equation (2x + 3)2 + 8(2x + 3) + 11 = 0? Use u substitution and the quadratic formula to solve.
lawyer [12517]

Answer:

x=-2.38

x=-4.62


Step-by-step explanation:

The question is (2x+3)^2+8(2x+3)+11=0

We let u=2x+3, so the equation becomes:

u^2+8u+11=0

Where a=1, b=8, c=11


By applying the quadratic formula, we arrive at:

Quadratic formula: \frac{-b+-\sqrt{b^2-4ac} }{2a}

Substituting yields: \frac{-8+-\sqrt{(8)^2-4(1)(11)} }{2(1)}\\=\frac{-8+-\sqrt{20} }{2}\\=\frac{-8+-2\sqrt{5} }{2}\\=-4+\sqrt{5}, -4-\sqrt{5} }

We let u=2x+3, thus x calculates to:

u=2x+3\\(-4+\sqrt{5})=2x+3\\x=\frac{-7+\sqrt{5}}{2}=-2.38

and

u=2x+3\\(-4-\sqrt{5})=2x+3\\x=\frac{-7-\sqrt{5}}{2}=-4.62


The solutions to the equation are x=-2.38 (rounded to 2 decimal places) and x=-4.62 (rounded to 2 decimal places)

A ramp with a constant incline is made to connect a driveway to the front door and 4 feet from the driveway the height of the ra
zzz [12365]

The correct response is:

3 inches rise for every foot in length

Explanation:

To derive the rate of change, we need to compute the difference in height and the difference in distance. The rate of change is expressed as rise/run, or

(change in height)/(change in length).

The respective heights at the specified points are 18 inches and 12 inches, resulting in a change of 18-12 = 6 inches.

The corresponding lengths at those points are 6 feet and 4 feet, yielding a change of 6-4 = 2 feet.

This implies our rate of change is (6 inches)/(2 feet), which simplifies to (3 inches)/(1 foot), indicating a rise of 3 inches for each foot of incline on the driveway.
