Answer:
3.64 × 10(raised to the power 7)
2.6 × 10⁴
Should be four times to get in between 9 and 10
This expression cannot be simplified, as you cannot add or subtract variables raised to different exponents.
They are both the same. There are 60 seconds in one minute, so 60*3 is 180. Since 180=180, they are equal.

Answer:
65.45
Step-by-step explanation:
Zscore = (x - mean) / standard deviation
x = score
Percentage below C :
D = 18% ; F = 12%
Sum = 30%
Obtain the Zscore for the proportion below D
P(Z < 0.30) = -0.524
Hence, Zscore = -0.524
Put Zscore = -0.524 in the equation :
-0.524 = (x - 72) / 12.5
-0.524 * 12.5 = x - 72
-6.55 = x - 72
-6.55 + 72 = x
x = 65.45
To receive a grade of C or better, score must be atleast 65.45
