A store owner bought a painting for $120. She is selling it for $190. What is the percent markup on the painting
stiks02 [169]

Answer:

The markup percent on the painting is 58.3%

Step-by-step explanation:

Here, The Cost price of the painting = $120

The selling price of the painting = $190

Hence, the total profit on the painting = Cost Price - Selling price

or Profit =  $190  - $120 = $70

Now, Markup % =  (Gross Profit / cost)  x 100

⇒Markup % = \frac{70}{120}  \times 100 = 58.3

Hence, the markup percent on the painting is 58.3%

If an archer shoots an arrow straight upward with an initial velocity of 160
HACTEHA [7]

Answer:

maximum height of the arrow will be 408 m

Step-by-step explanation:

We have given the function of height as h(t)=-16t^2+160t+8

We know that first derivative of height will be velocity

So first derivative of height

\frac{dh}{dt}=-32t+160

v(t)=-32t+160

We know that at maximum height velocity will be zero

-32t+160=0

t = 5 sec

Sp arrow will be at maximum height at t = 5 sec

So height at t = 5 sec will be

h(5)=-16\times 5^2+160\times 5+8=408m

So maximum height of the arrow will be 408 m
