Step-by-step explanation:
I think it would be $70.25
Answer:
{x I - 12 < x < 7}
Step-by-step explanation:
Fuaad solved an absolute value inequality and expressed the solution as - 12 < x < 7.
So, the value of x lies between - 12 and 7 but not including - 12 and 7.
Option C will give another way to show Fuaad's solution.
It is {x I - 12 < x < 7}, which means x is a variable which belongs with in the interval (- 12, 7). (Answer)
The answer: it is not in a quadrant, true
Answer:
Astronomers.
Step-by-step explanation:
In many, many ways we can use geometry in astronomy. One of the most or important example is that when astronomers find the distance between the different celestial bodies and they also find the tilt of any planet they uses geometry .
And in this field other uses of geometry when planets orbiting around the sun or satellites orbiting around there planets astronomers uses geometry to find the speed and velocity of the planets.
Answer:
The sidewalk is 2 feet wide
Step-by-step explanation:
The area of the sidewalk is given as 80 square feet
The length and width of pool
including side walks will be;
10 + 2x and 6 + 2x
To get the area of the side walk
That will be area of total minus area of the pool
That will be ;
(10 + 2x)(6 + 2x) - 10(6) = 80
60 + 12x + 20x + 4x^2 - 60 = 80
4x^2 + 32x -80 = 0
x^2 + 8x -20
x^2 + 10x - 2x - 20 = 0
x(x + 10) -2(x + 10) = 0
(x-2)(x + 10) = 0
x = 2 or -10
since width cannot be negative;
The sidewalk is 2 feet wide
