A square has a perimeter of 100cm What is the length of each side?

Answers

Answer 1
Answer:

Answer:

each side of the square is 25cm

Step-by-step explanation:

this is because of two things:

1. a square has equal sides

2. the perimeter is all the sides added together.

so if you call the length of one side x, you can make this equation:

x + x + x + x = 100

combine like terms

4x = 100

divide both sides by 4

x = 100/4

x = 25
Answer 2
Answer:

Answer:

25 cm

I hope this helps!

Find x of this shape.

Answers

Answer:

x = 9

Step-by-step explanation:

M is at the midpoint of GA and N is at the midpoint of HA, hence

MN is a mid-line segment and is half the length of GH, that is

5x = (1)/(2)(15x - 45) ← multiply both sides by 2

10x = 15x - 45 ( subtract 15x from both sides )

- 5x = - 45 ( divide both sides by - 5 )

x = 9

Which statement is true? P(age between 25 and 35 years|hemoglobin level between 9 and 11) P(age between 25 and 35 years)
P(hemoglobin level between 9 and 11|age between 25 and 35 years) = P (hemoglobin level between 9 and 11)
P(hemoglobin level between 9 and 11|age between 25 and 35 years) = P(age between 25 and 35 years)
P(age between 25 and 35 years|hemoglobin level between 9 and 11) = P(hemoglobin level between 9 and 11|age between 25 and 35 years)
P(hemoglobin level between 9 and 11) = P(age between 25 and 35 years)..

Answers

P(hemoglobin level between 9 and 11) = P(age between 25 and 35 years)..

From its resting position, how long does it take the weight to bounce one direction, then the other, and then return to its resting position?

Answers

the first position is at rest, that is 0 seconds, then it goes one direction up to 0.75 seconds and starts returning to original position, it reaches original position again at 1.5 seconds, and goes in the opposite direction up to 2.25 seconds, then starts returning and hits original position once again at 3 seconds

Using Binomial Theorem, we will know that each term will have binomial coefficients nCk (n choose k) for 0 ≤ k ≤ 6

Here, we have n = 6 so coefficients are ₆C₀, ₆C₁, ₆C₂, ₆C₃, ₆C₄, ₆C₅, ₆C₆

Which is same as 1, 6, 15, 20,15, 6, 1, respectively, therefore answer is B.
