Answer:

200

Step-by-step explanation:

Janet = x + 75

2x = 250

x/Kathy = 125

x + 75/Janet = 125 + 75

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.

Someone please help me!

HACTEHA [7]

Answer:

B and C describe vertical angles

Step-by-step explanation:

Point R will be the common vertex of any possible pair of vertical angles.

For a given line segment, such as AE, one end will designate a side of one of the vertical angles, and the other end will designate a side of the other angle of the pair.

For example, Choice B uses the crossing segments TN and FL and identifies the vertical angles TRF and NRL.

Choice C uses segments FL and AE to identify the vertical angles LRE and FRA.

Choice A does not involve crossing segments. Choice D makes use of segment AE, but the other points S and N are not on the same segment.
