She had 2,500 stamps before she gave 1% to her brother, since 2,475 is 99%, i just calculated this equation: p/w = a/100

Answer:

2500

Step-by-step explanation:

If Jasjeet gave away 1%, that means she has 99% left.

Put the 99% over 100, so you can drop the % sign.

Then you're going to cross multiply that with 2475/ ?. The ? is the unknown aka original ammount of stamps. The 2475 is the 99% of stamps she still has.

the quadratic function h (t)=-16t^2+150 models a balls height, in feet, over time, in seconds, after it is dropped from a 15 sto
natulia [17]
Hello! Lets solve this :)
So for the first question :
h(t) = -16t^2 + 150
h(0)= -16 (0)^2 + 150
h(0)= -16(0) + 150
h(0)= 0 + 150
h(0)= 150 feet

Second question
We need to find here the time when the ball hit the ground; or when the height h(t) is 0.
In equation form
h(t) --> 0=16t^2 + 150
16t^2 = 150
t^2=150/16
t= <span>√150/16
t= 5</span><span>√6/4
t= 5 (2.45)/4
t= 3.06 seconds
</span>
Hope this helps! If you have any other questions or would like further explanation just let me know! :)
