Answer:
How many more games will Aditi have to win to have an 80% winning record?
<u>The linear equation that models this is:</u>
12 + x = 0.80(x+20)
<u>Aditi would have to win</u> 20 <u>more games to have an 80% winning record. </u>

The answer is £16265.28
That should be correct
Card P's balance increased by $3.43 more than Card Q's balance. The accumulated total on Card P over the 4 years is $1080.70 and the accumulated total of Card Q is $1,206.28. Based on the principal outlay however, Card P would have netted a higher interest over Card Q when the principal is subtracted from the accumulated value. (For eg. Card P accumulated value $1080.70 less Principal $726.19 equals $354.51).The interests over the 4 years period would be $354.51 and $351.08 respectively, hence Card P having an increase in balance of $3.43 over Card Q.
Answer:
part A; B and Part B; pencils
Step-by-step explanation:
you want to find out how many pens and pencils you cn buy with that 90$ so you want to do
.75y+.15x=90
pens=50
pencils=50
but you want to add .75+.15 which = .90
then you divide 90/.90
and that equals 100
then split it up and each gets 50
Answer:
Step-by-step explanation:
The position function is
and if we are looking for the time(s) that the ball is 10 feet above the surface of the moon, we sub in a 10 for s(t) and solve for t:
and
and factor that however you are currently factoring quadratics in class to get
t = .07 sec and t = 18.45 sec
There are 2 times that the ball passes 10 feet above the surface of the moon, once going up (.07 sec) and then again coming down (18.45 sec).
For part B, we are looking for the time that the ball lands on the surface of the moon. Set the height equal to 0 because the height of something ON the ground is 0:
and factor that to get
t = -.129 sec and t = 18.65 sec
Since time can NEVER be negative, we know that it takes 18.65 seconds after launch for the ball to land on the surface of the moon.
