(-17.8) / (1/6)....when dividing with fractions, flip what u r dividing by, then multiply

-17.8 * 6 = - 106.8

mistake made in Line 2.....Dante forgot the negative sign in front of 17.8

Answer:

Dante made an error in step 2.

Step-by-step explanation:

The given expression is −17.8 ÷ 1 over 6.

In step 1, we change the division sign to multiplication sign. For this we use the below rule

$\frac{a}{b}$ ÷ $\frac{c}{d}=\frac{a}{b}\times\frac{d}{c}$

Using this rule, we have the second step as shown below

$-17.8]times6$

Now, finally we multiply and get

-106.8

Therefore, Dante made an error in second step. He forgot to include the negative sign.

Someone pls help I'm confused

Answer:

4x + 8x = 180

12x = 180

divide by 12 on both sides:

X = 15

4 x 15 = 60 degrees

8 x 15 = 120 degrees

2) 83,97,85,84,96, 80,80,87,91<br> Mean median and mode

marusya05 [52]

$\text {Hi! Let's Solve this Problem!}$

$\text {Before you find the Mean, Medina and Mode you must put the numbers in order.}$

$\text {Before: 83, 97, 85, 84, 96, 80, 80, 87, 91}\\\text {After: 80, 80, 83, 84, 85, 87, 91, 96, 97}$

$\underline {\text {Mean}}$

$\text {To Find the Mean you must Add all the Numbers then Divide.}$

$\text {Add:}$ $\text 80+80+83+84+85+87+91+96+97=\fbox {783}}$

$\text {Divide:}$ $\text {783/9=}$

$\text {The Mean Is:}$

$\fbox {87}$

$\underline {\text Median}}$

$\text {To find the Median you find the number that's in the middle of the set.}$

$\text {Put your Left Pointer Finger on 83. Put your Right Pointer Finger on 91.}$

$\text {Move your Left Finger to the Right. Move your Right Finger to the Left.}$

$\text {Once your Left Finger makes it to 84 and your Right Finger makes it to 87}$ $\text {it shows that 85 is left in the middle.}$

$\text {The Median Is:}$

$\fbox {85}$

$\underline {\text {Mode}}$

$\text {Finding the Mode means finding the number}$ $\text { that shows the most in the number set given.}$

$\text {Since 80 is the number that is showing more than any other number}$ $\text {this tells us that 80 is our Mode.}$

$\text {The Mode Is:}$

$\fbox {80}$

$\text {Best of Luck!}$

This is a polygon and I need help finding the missing angle ?

allsm [11]

First, you need to know that the total (degrees) of the interior angles is 360 because this is a quadrilateral.

The unnumbered angle is 109 degrees. We know this because the angle labeled 71 degrees and the unnumbered angle are supplementary. So you subtract 180 from 71 to get 109.
$180-71=109$

To solve for x, we need to realize the other numbers playing into the angles' values. To make solving this easier, I'm gonna assign letters to the angles.

(10x+6) is angle A.

(13x-2) is angle B.

(8x-1) is angle C.

and 109 (the one we solved) is angle D.

We know that the total of the interior angles is 360, so we can add the 2 from angle B and the 1 from angle C to 360. This is because these numbers are subtracted from the other values.
$360+2+1=363$

Now, we have to subtract the 6 from angle A from 363, because the 6 is added to the other values.
$363-6=357$

Now we have to subtract 109 from 357 because you want to get the x's by themselves. Since you're solving for x.
$357-109=248$

That leaves you with 248. Now you add all the x's up to get the total number of x's. You have 10x from angle A, 13x from angle B, and 8x from angle C.
$10x+13x+8x=31x$

You get 31x. To get what x is, you divide 248 by 31.
$\frac{248}{31} =8$

That equals 8. So now that you know that x equals 8, if you need to find the values of the angles, you just plug in the numbers into the formulas.

$(10(8))+6= 86$
$(13(8))-2=102$
$(8(8))-1=63$
$109$

Check your work by plugging your answers in and seeing if they add up to 360.
$86+102+63+109=360$

Which they should:)

So...
angle A= 86
angle B=102
angle C=63
angle D=109

and x=8

Hope this helped!!!

( 3+2 )²<br>simplify it

Pavlova-9 [17]

Answer:

First we have to finish the brackets, always

3+2=5, so

it will be 5 square

which means you have to multiply 5 by itself

5×5=25

so your answer is 25
