Answer:

Step-by-step explanation:

since we can see that the lines are parallel

and we can see that the both are interior angles and when we sum up both angles we get 180

2x - 5 + 45 = 180

2x + 40 =180

2x = 180 - 40

2x =140

x = 140/2

x = 70

the diameter of a pearl is about 4×10-¹⁴ cm and the diameter of an atom is about 10-¹¹ m. how much larger than an atom is a pear

serious [3.7K]

Answer:

The diameter of an atom is 25000 times the diameter of a pearl.

Step-by-step explanation:

Given that,

The diameter of a pearl is $4\times 10^{-14}\ cm$

The diameter of an atom is $10^{-11}\ m=10^{-9}\ m$

Taking the ratio,

$\dfrac{\text{diameter of an atom}}{\text{diameter of a pearl}}=\dfrac{10^{-9}\ m}{4\times 10^{-14}\ m}\\\\=25000$

So, the diameter of an atom is 25000 times the diameter of a pearl.

Answer: (b) -7/2, 6.

Step-by-step Explanation: We put x = 0; then y = 6; y-intercept of the line is (0,6).

For the slope: 4y = 24 - 14x; then, y = (-7/2)x + 6; the slope is -7/2.
