Answer: 210 percent increase
Step-by-step explanation: So w know the starting value is k so we can replace it with 1 dollar
now we know he bought the dresser for 1 dollar and sold it for 3.10 dollars
First we have to subtract the starting value 3.1 - the original value
3.1 - 1 = 2.1
then we have to divide that number by the starting value
2.1 divided by 1 = 2.1
Lastly multiply times 100 to get the percent increase
2.1 x 100 = 210 % increase
hope this helps mark me brainliest if it helped
The projectile has constant horizontal speed all the time and we can use this formula
x=Vax*t, where t is time it (projectile) takes to reach x=1000m
t=x/Vax=1000/50=20s
As we know we can split projectile trajectory in two parts and the time for each part is equal. We can conclude that time t=20s belong to first part where projectile is going up.
Formula for this type of movement is y=Vay-(gt∧2)/2
If we take acceleration of gravity g=10m/s∧2
we get y=200*20-(10*20∧2)/2=4000-2000=2000m
But if I calculate time it takes the highest point I get
t=Vay/g=200/10=20s
The highest point for that time is
y= H=Vay∧2/2g=200∧2/2*10=40000/20=2000m
This happened because the projecile is fired from the edge of a cliff which is above the sea line.
Good luck!!!
42 divided by -8 is -5.25 (-5 1/4)
<span>8 + 3{x - 2[x + 5(x + 3)]}.
=</span><span>8 + 3{x - 2[x + 5x + 15]}
=</span>8 + 3{x - 2[6x + 15]}
=8 + 3{x - 12x -30}
=8 + 3{- 11x -30}
= 8 - 33x - 90
= - 33x - 82
Answer:
z-score for 900 points = -4
Step-by-step explanation:
To find the z scores
z=(x-mean)/standard deviation
so
z=(900-1500)/150
z= -600/150
