The speed of light passing through water is 2.25% 10^8 meters/second. the speed of light passing through a diamond is 1.23x 10^8 meters/second what is the difference of the two speeds?

1.02 * 10^8.

Step-by-step explanation:

2.25 * 10^8 - 1.23 * 2.25

= (2.25 - 1.23)* 10^8

= 1.02 * 10^8 (answer)

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
