Answer:

y=3

Step-by-step explanation:

Regroup terms.

y+3=9-y

Subtract 3 from both sides.

y=9-y-3

Simplify  9-y-3  to  6-y

y=6-y

Add y to both sides.

y+y=6

Simplify  y+y  to  2y.

2y=6

Divide both sides by 2.

y= 6/2

then the answer is y=3

Unit Test / 16 of 25
Rzqust [24]

Answer:

30

Step-by-step explanation:

For the minimum free throws, he must put every throw to the basket.

So, let n be the number of throws for Tuesday, in which all the throws are successful.

So, over both the days, total free throws he makes= 15+n.

Total numbers of throws that went in the basket= 6+n.

As he wants at least 80% of his balls to go in the basket.

So, 6+n is greater than or equal to 809% of 15+n, i.e

6+n\geq \frac{80}{100}\times (15+n)

\Rightarrow 30+5n\geq 60+4n

\Rightarrow n\geq 30.

Hence, the minimum number of free throws required on Tuesday to reach his goal is 30.

How much is 400.00 invested at 9% interest compounded continuously be worth after 3 years
blagie [28]
COMPOUNDED
not simple interest,
compound interest is neat since you earn interest on the interest you earned

ok so what you use is F=Pe^(rt)
F=future or ending amount
P=present amount
e=base of the natural  log (some digits are 2.71828182845)
r=rate in decimal
t=time in years

presen amount is 400
rate is 9% or 0.09
time is 3 years

F=400e^(0.09*3)
F=400e^(0.27)
F=523.986
round
F=523.99
