Answer:
-69/200
Step-by-step explanation:
-0.345 is in decimal form.
In Fractional form (p/q)
=-345/1000
To simplify, divide the numerator and the denominator by the G.C.D(Greatest Common Divisor) of p and q.
In this case,G.C.D of 345 and 1000 is 5.
Simplified form=-69/200 [ANS]
$20×.25=$5
$20-$5=$15
$15×.15=$2.25
$15+$2.25=$17.25
$17.25 is your answer
In kilometers, the approximate distance to the earth's horizon from a point h meters above the surface can be determined by evaluating the expression

We are given the height h of a person from surface of sea level to be 350 m and we are to find the the distance to horizon d. Using the value in above expression we get:
Therefore, the approximate distance to the horizon for the person will be 64.81 km
