2 times 10^4 means 2 with 4 zeroes after it or 20000
4 times 10^6=4 with 6 zeros after it or 400000
compare
20000 and 4000000
we can see that 4000000 is 200 times of 20000
therefor the answer is C
we can also do
(4 times 10^6)/(2 times 10^4)=4/2 times (10^6)/(10^4)=2 times 10^2=200
answer is C
B=36
prisms give me the most difficulty
Answer:
Step-by-step explanation:
To obtain the standard form of the equation of the parabola y=2(x+4)^2-7, first perform the indicated operations:
y = 2[x^2 + 8x + 16 - 7], or
y = 2[x^2 + 8x + 9],
or y = 2x^2 + 16x + 18
None of the given possible answers match. The fourth one, D, is closest to the above result, differing only in the constant term (25 versus 18).
If Alexa's mom paid 1/2 of the $450:
$65
if Alexa's mom paid 1/2 of the remaining price:
$145
Alexa's mom paying 1/2 the $450:
$450 divided by 2 = $225
$225 - $120 = $105
$105 - $40 = $65
Alexa has $65 left to pay
Alexa's mom paying 1/2 of the remaining price after the student discount and Alexa payed $120:
$450 - $120 = $330
$330 - $40 = $290
$290 divided by 2 = $145
