We know that <span>Lola walks 4/10 mile to her friends house. then she walks 5/10 mile to the store.

To solve the problem we have to use addition.

4/10 + 5/10 = 9/10

Lola walks 9/10 miles. </span>

Find the measure of the arc. Second time posting this. Nobody is helping me...

Lyrx [107]

Answer:

Step-by-step explanation:

first lets add our two given angles, 90 (the little square) and 146

146 + 90 = 236

then subtract that from 360 to get our missing angle

360 - 236 = 124

so your answer is 124 degrees

Select the two values of x that are roots of this equation

Jet001 [13]

<h2>Hello!</h2>

The answers are:

B. $\frac{-3-\sqrt{29}}{2}$

C. $\frac{-3+\sqrt{29}}{2}$

<h2>Why?</h2>

We can use the quadratic equation to find the two values of x that are roots of the given equation. We must remember that most of the quadratic equations have two roots, however, we could find quadratic equations with just one root or even with no roots, at least in the real numbers.

Quadratic equation:

$\frac{-b+-\sqrt{b^{2}-4ac} }{2a}$

So,

From the given equation we have:

$a=1\\b=3\\c=-5$

Substituting it into the quadratic equation to find the roots, we have:

$\frac{-b+-\sqrt{b^{2}-4ac} }{2a}=\frac{-3+-\sqrt{3^{2}-4*1*-5} }{2*1}\\\\\frac{-3+-\sqrt{3^{2}-4*1*-5} }{2*1}=\frac{-3+-\sqrt{9+20} }{2}\\\\\frac{-3+-\sqrt{29}}{2}$

So,

$x_{1}=\frac{-3-\sqrt{29}}{2}\\\\x_{2}=\frac{-3+\sqrt{29}}{2}$

Hence, the correct options are B and C.

Identify the area of the figure rounded to the nearest tenth. HELP?!! I don't understand!! Please help and show your work!!

Alex73 [517]

Answer:

$67.5\ cm^{2}$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of rectangle (figure 1) plus the area of trapezoid (figure 2)

see the attached figure to better understand the problem

The area of the rectangle is

$A=15*3=45\ cm^{2}$

The area of the trapezoid is

$A=\frac{1}{2}[(15-9)+3)](8-3)$

$A=\frac{1}{2}[6+3)](5)=22.5\ cm^{2}$

The area of the figure is

$45\ cm^{2}+22.5\ cm^{2}=67.5\ cm^{2}$

Rus_ich [418]

Answer:

C 210

Step-by-step explanation:

To solve this, First we must take 42/3, Since it equals 14, we take 15x14 and find 210

(edit: to solve for Kim's missing values, you do the same with 2 and 32)

Two sides of a triangle are two consecutive number, whose area is 17.5cm². Find the numbers

AveGali [126]

Answer:

The numbers associated with the triangle are 5.437 and 6.437 centimeters, respectively.

Step-by-step explanation:

Two numbers are consecutives, when their difference is equal to 1. The area of the triangle is determined by the following formula:

$A = \frac{1}{2}\cdot n \cdot (n+1)$

$A = \frac{1}{2}\cdot (n^{2}+n)$

$A = \frac{n^{2}}{2}+\frac{n}{2}$

$n^{2}+n = 2\cdot A$

Where $n$ is the shortest length of the triangle, measured in centimeters.

And we get the following second-order polynomial:

$n^{2}+n -2\cdot A = 0$ (1)

If we know that $A = 17.5\,cm^{2}$ , then the shortest length of the triangle is:

$n_{1} = 5.437\,cm$ and $n_{2} \approx -6.437\,cm$

Since length is a positive variable, the only possible solution is:

$n\approx 5.437\,cm$

Then, the numbers associated with the triangle are 5.437 and 6.437 centimeters, respectively.
