What is the conversion factor from meters to centimeters?
I am Lyosha [343]

Answer: there are 100 centimeters in 1 meter. Meters to centimeters multiply by 100. Centimeters to meters divide by 100.

Step-by-step explanation:

Meters to centimeters multiply by 100

(10,000 m ) (100) = 1,000,000 cm.

(100 m) (100) = 10,000 cm.

Centimeters to meters divide by 100.

100 cm / 100 = 1 meter

10,000 cm /100 = 100 m

Find the 50th term of the following<br> arithmetic sequence 5, 9, 13, 17?
yarga [219]

Answer:

201

Step-by-step explanation:

First you need to know the position to term rule and to find this you use a formula which is:

tn = an + b

Where tn is the term number,  a is the difference between the other terms.

So the tposition to term rule here is 4n+1.

Then we substitute n for the value 50 making it 4(50) + 1 = 201.

201 is the 50th term

Answer:

8√3 ≈ 13.86

Step-by-step explanation:

6√2 - 4√3 + | 3√(2²•2) -8√3 | + 2√2²•3

Every 2² get our from the square root and loses the ² :

6√2 -4√3 + | 2•3√2 -8√3 | + 2•2√3

Solve the multiplications and taking of the | | , the signal inside it changes:

6√2 - 4√3 +8√3 -6√2 +4√3

Now you group the similar terms and solve the possible operations:

6√2 - 6√2 +4√3 - 4√3 + 8√3

8√3 ≈ 13.86
