What is 12/27 (it is a fraction) turned into a decimal

1 answer:

3 0

First, we can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 12 and 27 using 3.

$\frac{12}{27}$ ÷ $\frac{3}{3}$ ≈ $\frac{4}{9}$

4 ÷ 9 = 0.44444444444444

Therefore, $\frac{12}{27}$ turned into a decimal is 0.44444444444444.

The vertex of this parabola is at (3,-2). When the x-value is 4, the y value is 3. What is the coefficient of the squared term i

bazaltina [42]

Answer:

the coefficient of the squared expression is 5.

Step-by-step explanation:

the equation of a parabola in its vertex form is y=a(x-h)²+k, where (h, k) is the vertex of the parabola.

in this case, h=3, k=-2, so y=a(x-3)-2

plug (4,3) in the equation: 3=a(4-3)²-2, a=5

The width of a rectangle is the length minus 3 units. The area of the rectangle is 10

sergeinik [125]

Answer:

w=2

Step-by-step explanation:

A=length times width (A=lw)

w= l-3

A=10

Substituting in, we get:

10= l(l-3)

Now, solve the equation.

10= $l^{2}$ -3l

$l^{2}$ -3l-10=0

(l+2) (l-5)=0 (factoring the equation)

Therefore, l= -2 or 5

Throw out the negative value because a length of rectangle will never be negative.

Now let's solve for width

Remember w=l-3

therefore

(5)-3=2

so, w=2

(honestly, this is easier to just do in your head. But here is the long form math if you happen to run into more complicated problems.)
