Answer:4600

Step-by-step explanation:

-6,-2,2,6,...

First term=a=-6

Common difference=d=-2-(-6)=4

Using the formula

Sn=n/2 x [2a + d x (n-1)]

S50=50/2 x [2x-6 + 4x(50-1)]

S50=25 x [-12 + 4 x 49]

S50=25 x [-12 + 196]

S50=25 x 184

S50=4600

Sum Of The first 50 terms is 4600

Answer: what you need to do is multiply 3 times 1 and add 2 to the sum that you get which would be 5/3 for the first one because you keep the same denominator! Just multiply the denominator the bottom number and add the numerator the top number to your sum that you got from multiplication! Do that for all of them and you should get an improver fraction!

:)

Finding the reciprocal is easy just flip the numbers I’m in 6th grade I learn this already!

For example just flip 3/7 to 7/3

Help me, please. Please also explain to me why you picked your answer.

Answer: Lower left corner  \frac{29}{18+29} \times 100

We have 29 people who chose fishing out of 18+29 people who filled out the survey. We don't use 60 because not everyone filled out the survey, and we're only focusing on survey participants. The "times 100" at the end will move the decimal point 2 spots to the right, and convert it to percent form.

For example, if you had 2 people who liked fishing out of 8 total then 2/8 = 0.25 = 25% of the people like fishing.

What are the values of K and M? And please show all work on how you got your answer
ipn [44]

Answer:

  k = 7

  m = 8

Step-by-step explanation:

The diagonals of a parallelogram bisect each other, so the two halves of each diagonal are the same length. That means ...

  m = 8

and

  k +4 = 11

  k = 7 . . . . . subtract 4 from both sides of the equation

(-1,4) and ( 1, -1) Find the distance between each pair of points
Nikolay [14]

Answer:

\sqrt{29}

Step-by-step explanation:

We are basically trying to find the hypotenuse of the triangle.

The distance between the x is 2, and the distance between the y is 5, which makes a length and a width.

Pythagrenum theorem: a^2+b^2=c^2

2^2 is 4, 5^2 is 25.

4+25 is 29.

The distance is \sqrt{29}.
