Answer:
28.35
Step-by-step explanation:
Answer:
-8 + x ≥ 9
Step-by-step explanation:
Let's look at your sentence:
The <u>sum of -8 and a number</u> is <u>at least 9 </u>what is the equation look like
Sum is the result of adding
At least 9 means that the number is 9 or greater.
So what you have here is an inequality expression:
Sum of -8 and a number
-8 + x
x here is the "number" since we do not know the value we will use "x" to represent that number.
At least 9
At least means that it is equal or greater, so we use this expression ≥
and so we use put that all together
-8 + x ≥ 9
The sun is 1.5*10^11 METERS from the Earth. In that case it takes approximately 8.3 minutes for sunlight to reach Earth.
<span>t=(1.5*10^11/3.0*10^8)/60=8.33 minutes </span>
<span>If you did want a hypothetical that puts the Earth at 1.5*10^11 kilometers from the sun, then it would take 8333.3 minutes for the sunlight to reach the "Earth's" surface. </span>
<span>t=(1.5*10^14/3.0*10^8)/60=8333.3 minute</span>
