now, notice, we didn't use the length of 30inches.... since the "l"'s cancel each other anyway, so it doesn't weight much on what the value for "h" is, by simply doing the substution of "w" from the Girth.
Answer:
$94.50
Step-by-step explanation:
A shoe store uses a 50% markup for all of the shoes it sells. What would be the selling price of a pair of shoes that has a wholesale cost of $63?
(63)(1+0.50)=63*1.50=63+31.50=94.50
Sum of interior angles of a triangle = 180°
x+40+30= 180°
x+ 70=180
x= 180-70
x= 110°
Answer:
(a) The ball will hit the ground after 3 seconds
(b) The maximum height is 6.125
Step-by-step explanation:
Given

Solving (a): When the frisbee will hit the ground?
To do this, we set h(t) to 0
So, we have:


Expand

Factorize

Factor out t - 3

Split:

Solve for t in both equations


Time can't be negative; So:

Solving (b): How height the frisbee will go?
First, we calculate time to reach the maximum height

Where:

By comparison:

So:




So, the maximum height is:


Add all of the numbers tougher and that will give you your answer
