Answer:
2.5 x 
miles
Step-by-step explanation:
We are given that 1 light year ≈ 5.9 x 
miles so:
- 4.3 x 10² light year · <u>5.9 x </u><u> miles </u>
- 1 light year
Multiply 4.3 an 5.9 and round to 2 significant digits then add the exponents:
≈25 x 
This is not the scientific notation since the number is not between 0 and 10 so we move the decimal point by 1 place to the left. We then add 1 to the exponent to obtain the final answer:
≈ 2.5 x miles

Answer:
see explanation
Step-by-step explanation:
Given a line joining the midpoints of 2 sides of a triangle, the midsegment
Then the midsegment is parallel to and half the measure of the third side of the triangle, thus
XY = 2KL = 2 × 42 = 84
Since J is the midpoint of XY, then
JY = 0.5XY = 0.5 × 84 = 42 and
JK = 0.5YZ = 0.5 × 76 = 38
Answer:
22%
Step-by-step explanation:
Divide 2,650 by 100:
2,650/100=26.5
Then divide 3233 by the dividend:
122=122%
Now you can see that there is a 22% percent increase over 100%, theefore making our answer 22%.
