72.3 + (-39.1)

joja [24]

Answer:

72.3 - 39.1 = 4tens - 7ones + 2tenth

Step-by-step explanation:

Give the expression 72.3 + (-39.1)

opening the parenthesis:

= 72.3 + (-39.1)

= 72.3 - 39.1

Breaking the decimal values into place values

72.3 = 7tens + 2units + 3tenth

72.3 = 7(10)+2(1)+3(1/10)

72.3 =70+2+0.3

Similarly for 39.1

39.1 = 3tens + 9units + 1tenth

39.1 = 3(10)+9(1)+1(1/10)

39.1 =30+9+0.1

72.3 - 39.1 = 70+2+0.3 - (30+9+0.1)

72.3 - 39.1 = 70+2+0.3 - 30-9-0.1

72.3 - 39.1 = 70-30+2-9+0.3-0.1

72.3 - 39.1 = 40 - 7 +0.2

72.3 - 39.1 = 4tens - 7ones + 2tenth

Which statement is true about the extreme value of the given quadratic equation?

ICE Princess25 [194]

Answer:

Option B. The equation has a maximum value with a y-coordinate of -21.

Step-by-step explanation:

The correct quadratic equation is

$y=-3x^{2}+12x-33$

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex represent a maximum

Convert to vertex form

Factor -3

$y=-3(x^{2}-4x)-33$

Complete the square

$y=-3(x^{2}-4x+2^2)-33+12$

$y=-3(x^{2}-4x+4)-21$

Rewrite as perfect squares

$y=-3(x-2)^{2}-21$

The vertex is the point (2,-21)

therefore

The equation has a maximum value with a y-coordinate of -21

What is the solution of this equqtion? 4+ 1/4 w=6

ale4655 [162]

Answer:

w = 8

Step-by-step explanation:

4+ 1/4 w=6

Subtract 4 from each side

4-4+ 1/4 w=6-4

1/4w = 2

Multiply each side by 4

4* 1/4 w=2*4

w = 8

If I cut 2/3 of a pie and put the big piece on my plate. Then eat 1/4 of the piece. What fraction of the original pie did I eat.

Hunter-Best [27]

If you took $\frac{2}{3}$ of a pie then only ate $\frac{1}{4}$ of that slice, you ate $\frac{1}{4}$ of $\frac{2}{3}$ .

$\frac{2}{3} * \frac{1}{4} = \frac{2}{12}$

Simplify.

$\frac{2}{12} = \frac{1}{6}$

So, you ate 1/6 of the pie.
