Use the formula 0 = b^2-4ac
0 = -b^2-4(2)(-9)
0 = -b^2+72
b^2 = 72
b = square root of 72
b = 2 real numbers
20
empties 25%
25%=1/4
1/4 of 20 is 5
20-5=15
15 left
how much more must be removes so it reaches 2/5 of 20
2/5 of 20=40/5=8
15-what=8
minus 15 both sides
-what=-7
multipy-1
what=7
answer is 7 more gallons must be removed
1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 are all the factors of 60. If a list includes any number other than what is listed here, it is NOT a choice.
Answer:
1.50.
Step-by-step explanation:
.20×7.50=1.50
the total cost now will be 9.00
Log(3) + log(x)=log(66)
log(x)=log(66)-log(3)
log(x)=log(66/3)
log(x)=log(22)
x=22
