<span>We can use the proportion. We already know that Dixon is 6 ft tall and that his shadow is 9 ft long. Also we know that the shadow of his sister is 6 ft long. 6 : x = 9 : 6, or 6 / x = 9 / 6. After that we will cross multiply : 9 * x = 6 * 6, 9 x = 36 , x = 36 : 9, x = 4. Answer: Ariadne is 4 feet tall.Hope I helped! :) Cheers!</span>
Answer:
80 minutes or 1 hour 20 min
Step-by-step explanation:
we know that
The speed is equal to divide the distance by the time
Let
s -----> the speed in miles per hour
d ----> the distance in miles
t ----> he time in hours
so
solve for t
we have
substitute and solve for t
Convert to minutes
(5+5⁴)-(x⁴-2)=
(put out the brackets)
=(5+5x⁴)+(-1)(x⁴)+(-2)(-1)=
=5+5x⁴-x⁴+2=
(combine like terms)
=x⁴(5-1)+(5+2)=
=4x⁴+7 is your answer
