Since that angle is 45 degrees, the white triangle is an isosceles triangle. Therefore, the hight of the big triangle is equal to 12. The are of the shaded triangle is 4x12/2 = 24

4/10= heeeeeeellllllppppppppppppp

Rudik [331]

4/10 is equal to 2/5, and 0.4.

2/5 can be found by simplifying the fraction (dividing top and bottom by 2). 0.4 can be found by dividing 4 by 10.

I hope this helps!

How many solutions does this system of linear equations have? Explain. 1= 2 =1+3 2

Neporo4naja [7]

Answer: There are no real solutions.

Step-by-step explanation:

We have the equation:

x = y^2

y = x + 3/2

To solve this, we can start by noticing that x is already isolated in the first equation, then we can replace it in the second equation to get:

y = y^2 + 3/2

And now we can rewrite this as:

y^2 - y + 3/2 = 0

This is a quadratic equation, and the solutions can be calculated with Bhaskara's equation, the solutions are:

$y = \frac{-(-1) +- \sqrt{(-1)^2 - 4*3/2*1} }{2*1} = \frac{1 + \sqrt{-5} }{2}$

We have a negative number inside the square root, this means that the solutions are complex numbers.

Then we can conclude that the system of equations has no real solutions.

A mixture of 60 liters of paint is 25% red tint, 30% yellow tint and 45% water. 9 liters of yellow tint are added to the origina

Jlenok [28]

The percentage of yellow tint in the new mixture will be 39.1304...%

Explanation

A mixture of 60 liters of paint is 25% red tint, 30% yellow tint and 45% water.

So, the amount of yellow tint $=(60*0.30)liters= 18$ liters.

Now, 9 liters of yellow tint are added to the original mixture. So, the total amount of yellow tint in the new mixture will be: $(18+9)liters= 27$ liters.
