Answer:
yards.
yards.
Step-by-step explanation:
We have been given that a square playground is surrounded by a sidewalk on all sides. The sidewalk is 
yards long on each side of the park.
Since side walk is 0.5 yard wide, so each side of playground will be 0.5 less than each side of sidewalk.
Since playground is square, so perimeter of playground will be 4 times the length of each side of playground.
Upon distributing 4 we will get,
Therefore, perimeter of playground will be yards or yards.
the right answer is actually 30,60,90, I got the answer right on the test
Answer:
$4060.
Step-by-step explanation:
We have been given that Jill gets a base pay of $1500 per month. She also earns a commission of 8% of her total sales. We are asked to find Jill's earnings for a month in which she has sales of $32,000.
Jill's earnings for the month would be base salary pus 8% of $32,000.
Therefore, the Jill's earnings for the given month would be $4060.

Answer:
both fireworks will explode 4.5 seconds after Firework B launches
Step-by-step explanation:
Given;
speed of firework A, 
= 360 ft/s
speed of firework B, 
= 340 ft/s
If the two fireworks explodes at the same height, then the height attained by the two fireworks are equal.
let the distance traveled by each firework before explosion = d
Distance = speed x time
Distance A = Distance B
speed A x time = speed B x time
let the time both fireworks explodes after Firework B launches = t
() t = ( ) t
360t = 340t
if firework B is launched 0.25 s before Firework A, for the time of the two fireworks to be equal since we are considering time (t) after 0.25 seconds, we will have;
360(t-0.25) = 340t
360t - 90 = 340t
360 t - 340 t = 90
20 t = 90
t = 90/20
t = 4.5 seconds
Therefore, both fireworks will explode 4.5 seconds after Firework B launches
