Answer:

19.2873015 (Done by a calculator) <---- could be wrong

Step-by-step explanation:

And fun fact:

Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not perfect square are members of irrational numbers. This means that they can't be written as the quotient of two integers.

Hope it helps!

Answer:

No real solution

Step-by-step explanation:

you cannot take the square root of a negative number, because a negative times a negative is always a positive. (In later math, you will learn there are imaginary numbers which can be the square roots of negative numbers, but that's way in the future of math classes.)

An office building has two elevators. One elevator starts out on the 4th floor, 35 feet above the ground, as it’s defending at a

The system of equations are y = 35 - 2.2x and y = 1.7x

Solution:

Given that, office building has two elevators.

One elevator starts out on the 4th floor, 35 feet above the ground, as it’s descending at a rate of 2.2 feet per second

Let "x" be the number of seconds for which the elevator is descending

Therefore, for "x" seconds the descended feet is 2.2x feet

The elevator is at 4 th floor, 35 feet above ground

Therefore, from 35 feet, the elevator has descended 2.2x feet for "x" seconds

Let "y" be the final position of elevator after "x" seconds

Therefore,

y = 35 - 2.2x

The other elevator starts out at ground level and is rising at a rate of 1.7 feet per second

Here, the elevator is rising at a rate of 1.7 feet per second

Therefore, for "x" seconds, the elevator has raised 1.7x feet

Here the elevator is at ground level, therefore

y = 1.7x

Thus the system of equations are y = 35 - 2.2x and y = 1.7x

Mr. and Mrs. Nelson are going to build a new home. They need to have working drawings of their house plans created by a design f

Mazyrski [523]

Answer:

The correct statements are (a), (c) and (d).

Step-by-step explanation:

The information provided is:

Rock the House Digital Designs charges $500.00 for the initial consultation with the Nelsons plus $50.00 for every additional hour of work for the house plans.
Elegant Home Architects charge $75.00 per hour for the house plans.
The variable h represent the number of hours for which Mr. and Mrs. Nelson hire the design firm.

The total charge for Elegance Home Architects, if the Nelsons choose them will be:

Total for Elegance = 75 × h = 75h.

Suppose the Nelsons hire the design firm for 15 hours.

Total for Elegance = 75 × h = 75 × 15 = $1,125

Total for Rock = 500 + (50 × h) = 500 + (50 × 15) = $1,250

So, the Elegance Home Architects will be cheaper.

Suppose the Nelsons hire the design firm for 25 hours.

Total for Elegance = 75 × h = 75 × 25 = $1,875

Total for Rock = 500 + (50 × h) = 500 + (50 × 25) = $1,750

So, the Rock the House Digital Designs will be cheaper.

Thus, the correct statements are (a), (c) and (d).
