<span>Think of how many square cm of stickers Samantha glued in 1 hour. If she did so much in 1/6 of an hour (10 minutes) and she continued at that speed, how many square cm could she do in 60 minutes? Remember to convert units from sq cm to sq m if required.</span>

1/6 of an hour is 10 minutes. For a precise answer, convert it to seconds. You will end up with 600 seconds. Divide the area of the sheet by 600 seconds.
1260/600 ~ 2 
With this result, Samantha glued approximately 2 stickers every second.

Tju [1.3M]

Answer:

2/9 = 0.22

Step-by-step explanation:

There are two ways to pick the first number odd and less than 5:  1 and 3.

With each of these, the second number drawn can be 1, 2, 3, 4, 5, 6, 7, 8 or 9.

This makes 18 total possibilities.

Out of these, the only ways to have a sum less than 5 are 1 and 1, 1  and 2, 1 and 3, and 3 and 1.  This is 4 ways out of 18:

4/18 = 2/9 = 0.22

Arrange the circles (represented by their equations in general form) in ascending order of their radius lengths. Tiles x2 + y2 −
sashaice [31]
When doing this, we would have to first straight them all out, and as we see above, they are just all over the place, and then, we would have to set them up as a sequence.

\left[\begin{array}{ccc}5x2 + 5y2 - 20x + 30y + 40 = 0\end{array}\right] would be our first step in this problem mainly because it contains the most terms in this aspect.

Then we would then x2 + y2 - 2x + 2y -1 = 0, then, 2x2 + 2y2 - 28x - 32y - 8 = 0.

These would only be our first 3 part of the sequence in this aspect.

The others would then be the following:

\boxed{x2 + y2 + 12x - 2y - 9 = 0 } \ then \ , \boxed{x2 + y2 - 4x + 4y - 10 = 0} \\ \\ then \ \boxed{x2 + y2 - 8x - 6y -20 = 0}

Thus, as we would have one more afterward, our last part of the sequence would then be the following.

\boxed{\boxed{4x2 + 4y2 + 16x + 24y - 40 = 0}}

I hope this was found helpful!

Solve for x in the equation x squared minus 12 x + 36 = 90. x = 6 plus-or-minus 3 StartRoot 10 EndRoot x = 6 plus-or-minus 2 Sta
goldenfox [79]

Answer: x = 6 plus-or-minus 3 StartRoot 10

Step-by-step explanation:

The given quadratic equation is expressed as

x² - 12x + 36 = 90

Rearranging the equation so that it takes the the standard form of

ax² + bx + c, it becomes

x² - 12x + 36 - 90 = 0

x² - 12x - 54 = 0

The general formula for solving quadratic equations is expressed as

x = [- b ± √(b² - 4ac)]/2a

From the equation given,

a = 1

b = - 12

c = - 54

Therefore,

x = [- - 12 ± √(- 12² - 4 × 1 × - 54)]/2 × 1

x = [12 ± √(144 + 216)]/2

x = [12 ± √360]/2

x = (12 ± 6√10)/2

x = 6 + 3√10
