QveST [7]3 years ago
7 0

Answer:

Step-by-step explanation:

We have

e^\frac{x}{2}^l^n^3 = 5\\

ln(e^\frac{x}{2}^l^n^3) = ln(5)\\\frac{x}{2}ln(3) = ln(5)\\\frac{x}{2} = \frac{ln(5)}{ln(3)}    \\x = \frac{2ln(5)}{ln(3)}

x = 2.929947041

to the third decimal is 2.930 (i might be wrong on the rounding part)

Which quotient is the same as the quotient 4.85÷0.7? 1. 48.5÷7 2. 48.5÷70 3. 485÷0.07 4. 485÷7
nikitadnepr [17]

Answer:

1. 48.5÷7

Step-by-step explanation:

4.85÷0.7

We can multiply both terms by 10 without changing the division problem

4.85 * 10 = 48.5

.7 * 10 = 7

48.5 ÷ 7 is the same as 4.85 ÷ .7
