Nicole worked 123 hours.

Now let me show you how i got that!

First you want to set up your equation.

13 times 9 plus 6= x

13 times 9= 117

117+6

117+6=123

x=123

A concrete patio is

astra-53 [7]

The length of concrete patio is 6.5 feet which is less than given 7 foot picnic table. So the concrete slab is not enough to fit a 7 foot picnic table

<em><u>Solution:</u></em>

Given that concrete patio is $5\frac{2}{3}$ feet wide

Area of concrete patio = $36\frac{2}{3}$ square feet

Therefore,

$\texttt{Width of concrete patio = }5\frac{2}{3}=\frac{5\times 3+2}{3}=\frac{17}{3}feet\\\\\text{Area of concrete patio = }36\frac{2}{3}=\frac{36\times 3+2}{3}=\frac{110}{3}feet^2$

Let us find the length of concrete patio

Concrete patio is usually of shape rectangle

Area of concrete patio = length x width

$\frac{110}{3} = length \times \frac{17}{3}\\\\length = \frac{110}{3} \times \frac{3}{17}\\\\length = \frac{110}{17} = 6.4705 \approx 6.5$

Therefore length of concrete patio is 6.5 feet

So it cannot fit the 7 foot picnic table. Since the length of concrete patio is 6.5 feet which is less than given 7 foot picnic table

Answer: 60 L

Step-by-step explanation:

Given

The measurement of a rectangular vessel is $40\ cm\times 30\ cm\times 50\ cm$

If we multiply the given terms then it will give the volume of the rectangular vessel in $cm^3$ .

So, the volume of the rectangular vessel is

$\Rightarrow V=60,000\ cm^3$

Also, we know $1000\ cm^3=1\ L$ i.e. to convert $cm^3$ to L, divide the result by 1000.

$\Rightarrow V=60,000\ cm^3=60\ L$

Which values of c will cause the quadratic equation –x2 3x c = 0 to have no real number solutions? check all that apply.

nika2105 [10]

The given quadratic equation will not have any real solution for c<-9/4.

The given quadratic equation is:

$-x^{2} +3x+c=0$

<h3>What is a quadratic equation?</h3>

Any equation of the form $ax^{2} +bx+c=0$ is called a quadratic equation with a≠0.

In order to have no real solution, the discriminant of a quadratic equation will be less than zero.

$D < 0$

$3^{2} -4(-1)(c) < 0$

$9+4c < 0$

$c < -\frac{9}{4}$

For $c < -\frac{9}{4}$ the given quadratic equation will have no real solutions.

Hence, the given quadratic equation will not have any real solution for c<-9/4.
