Answer:

44 cm

Step-by-step explanation:

The paper has two sides of 12 cm   = 24 cm

 and two sides of 10 cm   = 20 cm

      total   24 + 20 = 44 cm

Answer:

perimeter is 44cm

Step-by-step explanation:

We've learnt that perimeter equals the sum of all sides;

1) Make a list of your data:

Width is 10cm

Length is 12cm

2) Write the formula down and solve:

Perimeter = Length + width + length + width

P= 10+12+10+12

P=22+22

P= 44

Therefore the perimeter is 44cm

Crank

Complete question is;

Many states run lotteries to raise money. A website advertises that it knows "how to increase YOUR chances of Winning the Lottery." They offer several systems and criticize others as foolish. One system is called Lucky Numbers. People who play the Lucky Numbers system just pick a "lucky" number to play, but maybe some numbers are luckier than others. Let's use a simulation to see how well this system works. To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number. Any value can be​ picked, but for this​ exercise, pick 1 as the lucky number. What proportion of the time do you​ win?

Answer:

10%

Step-by-step explanation:

We are told that To make the situation manageable, simulate a simple lottery in which a single digit from 0 to 9 is selected as the winning number.

This means the total number of single digits that could possibly be a winning one is 10.

Since we are told that only 1 can be picked, thus;

Probability of winning is; 1/10 = 0.1 or 10%

The axis of symmetry for the graph of the function is f(x) = x2 + bx + 10 is x = 6. What is the value of b?
joja [24]

Answer:

b=-12

Step-by-step explanation:

we have

f(x)=x^{2}+bx+10

we know that

The equation of a vertical parabola into vertex form is equal to

y=a(x-h)^{2} +k

where

(h,k) is the vertex of the parabola

and the axis of symmetry is equal to x=h

In this problem we have the axis of symmetry x=6

so

the x-coordinate of the vertex is equal to 6  

therefore

For x=6+1=7 -----> one unit to the right of the vertex

Find the value of f(7)

f(7)=7^{2}+b(7)+10

f(7)=59+7b

For x=6-1=5 -----> one unit to the left of the vertex

Find the value of f(5)

f(5)=5^{2}+b(5)+10

f(5)=35+5b

Remember that

f(5)=f(7) ------> the x-coordinates are at the same distance from the axis of symmetry

so

59+7b=35+5b ------> solve for b

7b-5b=35-59

2b=-24

b=-12

Which of the following is true?
Ratling [72]

In this question, we're trying to find the inequality that is true.

To find your answer, we can convert the numbers in the absolute value:

|−5| < 4:

5 < 4 <em>false</em>

|−4| < |−5|:

4 < 5 <em>true </em>

|−5| < |4|

5 < 4 <em>false</em>

|−4| < −5

4 < -5 <em>false</em>

The only true inequality here would be |−4| < |−5|, since it works with the inequality sign.

Answer:

|−4| < |−5|

10n^{2} - 12 = -8<br> Please help
torisob [31]

The value for n is \frac{\sqrt{10} }{5}

<h3>solving for n</h3>

<u>given data</u>

10n^{2} - 12 = -8

making n the subject of the formula

10n^{2}  = -8 + 12

10n^{2}  = 4

divide through by 10

n^{2}  = 4 / 10

finding the square root of both sides

n = square root ( 4 / 10 )

n = \sqrt{\frac{4}{10}

n = 0.632 or \frac{\sqrt{10} }{5}
