Answer:

NQ = 3π units
sector area = 9π square units
24 +3π units

Step-by-step explanation:

The formulas tell you for a circle of radius 6, ...

C = 2π(6) = 12π

A = πr² = π(6²) = 36π

Arc NQ is 1/4 of the circumference of the circle, so will have length ...

NQ = 1/4C = 1/4(12π)

NQ = 3π . . . . units

b) Each sector is 1/4 the area of the circle. The area of one sector is ...

sector area = 1/4A = 1/4(36π)

sector area = 9π . . . . square units

c) The total path length is equal to the sum of the lengths of the pieces of the path length. Each radius is 6 units.

PRQNP = PR +RQ +QN +NP

= PR +RQ +QN +NR +RP

= 6 +6 +3π +6 +6

path length = 24 +3π . . . . units

Numerical answers (rounded to hundredths):

NQ ≈ 9.42 u

area ≈ 28.27 u²

PRQNP = 33.42 u

There are __ moles in 1.26 x 10^24 particles

lianna [129]

Answer:

There are 2.1 moles in $1.26 \times 10^{24}$ particles.

Step-by-step explanation:

Given : $1.26 \times 10^{24}$ particles

To find : Number of moles in given particle.

Solution : Since we know,

1 mole = $6\times 10^{23}$ particles.

So, 1 particle = $\frac{1}{6\times 10^{23}}$ moles

$1.26 \times 10^{24}\text{particle}=\frac{1.26 \times 10^{24}}{6\times 10^{23}}\text{moles}$

$1.26 \times 10^{24}\text{particle}=\frac{1.26 \times 10^{24-23}}{6}\text{moles}$

$1.26 \times 10^{24}\text{particle}=0.21\times 10\text{moles}$

$1.26 \times 10^{24}\text{particle}= 2.1\text{moles}$

Therefore, There are 2.1 moles in $1.26 \times 10^{24}$ particles.

HELP ME I NEED TO KNOW

OleMash [197]

I think it is 45.00 because you multiply -4.50 x 5= -22.5. The reason you multiply x4.59 times 5 is because he takes away 4.50 every day for 5 days. And then you do 67.50-22.5=45.00.

schepotkina [342]

It is a.1

(1+5) - 2(4(1)-1) = 0

(6) - 2(3) = 0

6 - 6 = 0

0=0
