the stick number is a knot invariant that intuitively gives the smallest number of straight "sticks" stuck end to end needed to form a knot. Specifically, given any knot K, the stick number of K, denoted by stick (K), is the smallest number of edges of a polygonal path equivalent to K.

Write an expression that is equivalent to

Answers

Answer:

13a+15b+18 is the answer hope it helps

Answer:

[tex]5(a+3b)+6+8a+12=13a + 15b + 18[/tex]

Step-by-step explanation:

Expanding rules (and rearranging) gives us that

[tex]5(a+3b)+6+8a+12\\= (5a + 15b) + 8a + (6 + 12)\\= (5a + 8a) + (15b) + (18)\\= 13a + 15b + 18[/tex]

Contributions to the annual Grayson School fund raising campaign were 10% greater in 1984 than they were in 1983. In 1983, contributions were 15% greater than they were in 1982. If contributions for 1984 total $8855, what was the total in 1982?

Answers

Answer:

find the value of X in the equation below 8x=2.4 (plz be fr)

Answers

Answer:

x=0.3

Step-by-step explanation:

divide 8 by both sides to isolate x

8x/8= 2.4/8

2.4/8= 0.3, leaving x by itself, giving us x=0.3

Hope this helps and have a great week!

answer:x = 0.3

Step-by-step explanation:Simplifying

8x = 2.4

Solving

8x = 2.4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Divide each side by '8'.

x = 0.3

Simplifying

x = 0.3

6 is 30% of what number​

Answers

Answer:

1.8

Step-by-step explanation:

Answer:

6 is 30 percent of 20 STEP 1 6 = 30% × Y

STEP 2 6 =  

30

100

× Y

Multiplying both sides by 100 and dividing both sides of the equation by 30 we will arrive at:

STEP 3 Y = 6 ×  

100

30

STEP 4 Y = 6 × 100 ÷ 30

STEP 5 Y = 20

Finally, we have found the value of Y which is 20 and that is our answer.

You can easily calculate a similar type of calculation by using any regular calculator, simply enter 6 × 100 ÷ 30 and you will get your answer which is 20

Clarkson University surveyed alumni to learn more about what they think of Clarkson. One part of the survey asked respondents to indicate whether their overall experience at Clarkson fell short of expectations, met expectations, or surpassed expectations. The results showed that 5% of the respondents did not provide a response, 26% said that their experience fell short of expectations, and 65% of the respondents said that their experience met expectations. (a) If we chose an alumnus at random, what is the probability that the alumnus would say their experience surpassed expectations

Answers

Answer:

0.04

Step-by-step explanation:

We are given that

The probability  that the alumnus did not provide response=5%

The probability  that the alumnus did not provide response=[tex]\frac{5}{100}=0.05[/tex]

The probability that the alumnus would say their experience  fell short of expectations=26%=0.26

The probability that the alumnus would say their experience met expectations=65%=0.65

We have to find the  probability that the alumnus would say their experience surpassed expectations.

We know that

Sum of all probabilities =1

Using the property

The  probability that the alumnus would say their experience surpassed expectations=1-(0.05+0.26+0.65)

The  probability that the alumnus would say their experience surpassed expectation=0.04

13. (07.05 MC) What is the solution to the equation 5x + 2(x - 4) = 5x + x - 10? (1 point) O​

Answers

Answer:

x = -2

Step-by-step explanation:

5x + 2(x - 4) = 5x + x - 10

First, we need to to multiply out the parathesis in the equation:

5x + 2(x - 4) = 5x + x - 10

5x + 2x - 8 = 5x + x - 10

Next, we can combine "like terms" to simplify the equation further:

5x + 2x - 8 = 5x + x - 10

7x - 8 = 6x - 10

Now we can isolate the variable "x" to one side:

7x - 8 = 6x - 10

x - 8 = -10

x = -2

To check our work, we can replace x with -2 in our original equation:

5x + 2(x - 4) = 5x + x - 10

5(-2) + 2 (-2 - 4) = 5(-2) + -2 - 10

-10 + 2 (-6) = -10 -2 - 10

-22 = -22

I hope this helps!

Noah spent some of his allowance on monday,1/8 of his allowance on Tuesday,1/8 of it on Wednesday and 2/8 of it on thursday.noah has none of his allowance money left.what fraction of his allowance did he spend on monday?explain

Answers

Answer:

Noah spent 4/8 of his allowance on Monday.

Step-by-step explanation:

Given that Noah spent some of his allowance on Monday, 1/8 of his allowance on Tuesday, 1/8 of it on Wednesday and 2/8 of it on Thursday, and has none of his allowance money left, to determine what fraction of his allowance did he spend on Monday the following calculation must be performed:

8/8 - (1/8 + 1/8 + 2/8) = X

8/8 - 4/8 = X

4/8 = X

Therefore, Noah spent 4/8 of his allowance on Monday.

Se necesitan cortar 3 cintas de 40 cm, 50 cm y 60 cm, en trozos igua-
les de manera que todas sean iguales y con la mayor longitud posible.
¿Cuántos trozos se cortarán?​

Answers

Answer:

Se cortarán en 15 trozos.

Step-by-step explanation:

Para determinar la longitud de cada trozo tal que todos los trozos tengan la misma longitud, se descompone factorialmente cada número:

[tex]40 = 2\times 2 \times 2 \times 5[/tex]

[tex]50 = 2\times 5\times 5[/tex]

[tex]60 = 2\times 2\times 3\times 5[/tex]

Ahora, determinamos el factor común de los tres números. Se puede encontrar que los tres números comparten un 2 y un 5. Entonces, el factor común es:

[tex]r = 2\times 5 = 10[/tex]

Este factor común representa la longitud de cada segmento. La cantidad de elementos se obtiene al dividir la suma de longitudes de las cintas por el factor común:

[tex]x = \frac{40\,cm+50\,cm+60\,cm}{10\,cm}[/tex]

[tex]x = \frac{150\,cm}{10\,cm}[/tex]

[tex]x = 15[/tex]

Se cortarán en 15 trozos.
