Answer:
x = -2
Step-by-step explanation:
Start:
216=6^(4x+11)
Use exponent property: (a^b*a^c)=a^(b+c)
Therefore:
216=6^(4x)*6^11
Simplify
216=(362797056)*6^(4x)
Divide
6^4x=(1/1679616)
Use exponent property: (a^b)^c = a^(b*c)
Therefore:
(6^4)^x=(1/1679616) OR (1296^x)=(1/1679616)
Use logarithms: log a b = c, where a^c=b
Therefore, log 1296 (1/1679616)=X
By logarithms property, log 1296 (1/1679616) = (log 10 (1/1679616))/(log 10 1296)
Use a calculator
x = -2
Given:
6kg 650g
1/2 kg
1/2 kg is equal to 500 grams
1 kg = 1000 grams
We need to convert these figures from kg to g.
6 kg * 1000g/kg = 6*1000g = 6,000 g
6,000 g + 650 g = 6,650 g
6,650 g ÷ 500 g = 13.3 round off to 13
13 * 500 g = 6,500
6 kg 650 g is nearest to 6,500 g.
Answer:
Ur answer will be D. Length: 50 in.; Width: 60 in.
Step-by-step explanation:
Just add all of them and then do the answer times 2.
Work:
A.
62 + 40 = 112
112 x 2 = 204
B.
20 + 11 = 31
31 x 2 = 62
C.
10 + 20 = 30
30 x 2 = 60
D.
60 + 50 = 110
110 x 2 = 220
