What is 3 1/2 multiplied by 2 1/4 as a mixed number or fraction

Nataly [62]

Hey there!

$3\frac{1}{2}$ × $2\frac{1}{4}$

$3\frac{1}{2}$ = $\frac{7}{2}$

$2\frac{1}{4}$ = $\frac{9}{4}$

$\frac{7}{2}$ × $\frac{9}{4}$

$7\times9 = 63$

$2\times4 = 8$

$\boxed{Answer: \frac{63}{8} ; 7\frac{7}{8} }$

Good luck on your assignment and enjoy your day!

Find all the zeroes of the equation. x4 – 6x2 – 7x – 6 = 0

NeX [460]

Answer:

-2, 3, -0.5 + 0.866i, -0.5 - 0.866i.

Step-by-step explanation:

As the last term is -6 , +/- 2 , +/- 3 are possible zeroes.

Try 2:-

(2)^4 - 6(2)^2 - 7(2) - 6 = -28 so 2 is not a zero.

3:-

(3)^4 - 6(3)^2 - 7(3) - 6 = 0 so 3 is a zero.

(-2)^4 - 6(-2)^2 - 7(-2) - 6 = 0 so -2 is also a zero.

Divide the function by (x +2)(x - 3), that is x^2 - x - 6

gives x^2 + x + 1

x^2 + x + 1

So we have x^2 + x + 1 = 0

x = [-1 +/- √(1^1 - 4*1*1)] / 2

= -1 + √(-3) / 2 , - 1 - √(-3) / 2.

= -0.5 + 0.866i, -0.5 - 0.866i

Is the given value a solution of the inequality

dsp73

Answer:

35 <5m

35/5 < 5m/5

7 < m

m = 8,9,10,11,12,.......

a + 6 $\geq$ 9

a + 6 - 6 $\geq$ 9 -6

a $\geq$ 3

a = 3,4,5,6,7,......

8-g > 5

8 -g +g > 5 +g

8 > 5 +g

8 -5 > 5 -5 +g

3 > g

g =4,5,6,7,8.......

A washer and dryer cost $793 combined, the washer costs $93 more than the dryer. What is the cost of the dryer?

frosja888 [35]

The dryer costs x.
The washer costs $93 more than the dryer, so it costs x+93.
The washer and the dryer cost $793 altogether.

$x+x+93=793 \\
2x=793-93 \\
2x=700 \\
x=\frac{700}{2} \\
x=350$

The cost of the dryer is $350.
