Answer:
d = 16.3 ft
Step-by-step explanation:
This is a right triangle, so we can use the Pythagorean theorem
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse
d^2 + 24^2 = 29^2 where d is the distance
d^2 +576 = 841
Subtract 576 from each side
d^2 +576-576 = 841-576
d^2 =265
Take the square root of each side
sqrt(d^2) = sqrt(265)
d = sqrt(265)
d =16.2788206
To the nearest tenth
d = 16.3 ft
Since 20% can be rewritten as 1/5, then we can multiply 18 by 5 to get 90, which is your answer. Hope this helps!
Do you understand what I did here?
Answer:
4
Step-by-step explanation:
Variable: X = Unknown Number
2x + 4 = x + 8
2x - x = 8 - 4
x = 4
Check:
2(4) + 4 = 4 + 8
8 + 4 = 12
12 = 12
the first answer choice, associative property of addition
hope this helps. gl!
