Wouldn't it be like 6.28?
I just set up a proportion of 3300000birth/525600min =xbirth/1minute but i'm not entirely sure if that's right

There could be more than 100 births per minute as long as it equals to 3.3 million

Solve the inequality
GenaCL600 [577]
-1 < c + 2 < 3....subtract 2 from all sections
-1 - 2 < c + 2 - 2 < 3 - 2...simplify
-3 < c < 1
==============================
32 > 16 - 4g > 12....subtract 16 from all sections
32 - 16 > 16 - 16 - 4g > 12 - 16....simplify
16 > -4g > -4 ...now divide all sections by -4, and change inequality signs
16/-4 < (-4/-4)g < -4/-4...simplify
-4 < g < 1
============================
6y + 1 > = 10
6y > = 10 - 1
6y > = 9
y > = 9/6 which reduces to 3/2 or 1 1/2

-3/2y > = 9 ....multiply both sides by -2/3, cancelling the -3/2 on the left...and change the inequality sign
y < = 9 * -2/3
y < = -18/3 which reduces to - 6

so y > = 9/6(or 1 1/2) or y < = -6

What is the factored form of the expression 9x2 + 6x + 1?
DanielleElmas [232]

Answer:

(3x + 1)²

Step-by-step explanation:

Given

9x² + 6x + 1 ← is a perfect square of the form

(ax + b)² = a²x² + 2abx +  b²

Compare like terms to find a and b

a²x² = 9x² ⇒ a² = 9 ⇒ a = \sqrt{9} = 3

b² = 1 ⇒ b = \sqrt{1} = 1

and 2ab = 2 × 3 × 1 = 6

Thus

9x² + 6x + 1 = (3x + 1)²

Write 10 x 10 x 10 x 10 x 10 with an exponent.<br> 10 x 10 x 10 x 10 x 10 =
lakkis [162]

Answer:

10^5

Step-by-step explanation:

Exponents are basically just saying how many times the number is multiplied by itself.

In the expression 10\cdot10\cdot10\cdot10\cdot10, we can see that 10 is being multiplied by itself 5 times.

So the exponent becomes 5, and the base is 10.

10^5.

Hope this helped!
