The answer is: k=-1

The explanation is shown below:

1. By the exponents properties, when you have equal bases, you must sum the exponents of all the bases.

2. Based on this, let's write only the exponents and let's solve for k to calculate its value:

-3+1+k=-3\\ k=-3+3-1\\ k=-1

Therefore, the answer is k=-1

10^{-3} \cdot 10 \cdot 10^k = 10^{-3}


10^{-3 + 1 + k} = 10^{-3}


Taking logs,


-3 + 1 + k = -3


k = -1

Illusion [34]

Answer: -9 degrees Fahrenheit

Step-by-step explanation:

Given: Temperature at 6:00 AM = -12 degrees Fahrenheit

Temperature increased each hour = \dfrac12 degrees Fahrenheit

Temperature increase in 6 hours = 6\times\dfrac12=3\text{ degrees Fahrenheit}

Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours

= -12+3 degrees Fahrenheit

= -9 degrees Fahrenheit

Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit

What is the value of n? n–2= 10n+ 4/2 Enter your answer in the box.
pentagon [3]

Answer:

-4 / 9

Step-by-step explanation:


 n - 2 = 10n + 4/2

 n - 10n = 4/2 + 2

 -9n = 4/2 + 4/2 ( taking LCM of 4/2 and 2)

 -9n = 8/2

 -9n = 4

    n = 4 / -9

   

   therefore n = -4 /9 ( since the minus sign doesn't make a difference whether placed at numerator or denominator) .

Maria has added 2 liters of pure water to 8 liters of a 48% sugar syrup. What is the concentration of the resulting solution?
amm1812
We know that
2 liters of pure water = 0 % of sugar 
8 liters of syrup = 48% of sugar

Water = (2 liters x 0%) = 0 total sugar liters
Syrup = (8 liters x 48%) = 3.84 total sugar liters
Total liter mix =8+2-----> 10 liters

Total liters of sugar = 0 + 3.84 = 3.84
if 10 liters-----------> 100%
 3.84 liters--------> x
X=3.84*100/10-----> x=38.4%

the answer is
 38.4%
