A steel company is making flat rectangular frames as a part of a new product they are launching Each frame will be cut out of a
Basile [38]

Answer:

The problem has no real solution, because the area of inside of the frame is bigger than the total area of the frame.

Step-by-step explanation:

Any way here is the mathematical explanation/solve to this statement.

As show in the graphic, there is a representation of the situation stated in the problem. So in order to calculate the area we have the next equation as a function of x.

Area:

A=b*h= (6+2x)(11+2x)\\\\A=28=66+12x+22x+4x^2}\\\\Simplifing\\\\4x^2+34x+38=0\\\\

Solving the equation to find the roots (values of x):

x=\frac{-b+- \sqrt{b^2-4ac} }{2a}=\frac{-34+-\sqrt{546} }{8}  \\\\solving\\\\x=-7.2\\\\x=-1.3\\

So mathematically there is no real answer, since x is a width must be positive number. And practically the outer area must be bigger than the inner area, and the inner area is given by 6 times 11, or 66 cm^2.

A baseball player had 4 hits in 8 games. At this rate, how many hits will the baseball player have in the next 28 games?
hoa [83]

Answer:

14

Step-by-step explanation:

I would say 14 because if you multiply 8 by 3 it would equal 24. And that is just below 28. Then, I tried to see if 8 x 4 would work, but that equaled 32. And both of those numbers are in between 28. So, if I multiplied 8 by 3 to get 24, I also multiplied the 4 by 3 which equals 12. So, I would say it would be 14.

What is the y-intercept of y+4=-1/4(x+2)
Hunter-Best [27]
Get the equation in slope-intercept form.

y + 4 = -\frac{1}{4}(x + 2)
y = -\frac{1}{4}(x + 2) - 4
y = -\frac{1}{4}x - \frac{1}{2} - 4
y = -\frac{1}{4}x -4.5

The y-intercept is (0, -4.5).
