A car drives 40 miles on local roads at 20 mph, and 180 miles on the highway at 60 mph, w Your dinner bill is $25 before tax. Th

Anastasy [175]

Answer and Step-by-step explanation:

$Let's~solve~your~problem!$

<em><u>Formula : </u></em>

<u></u> $speed=\frac{distance}{time}$

<em><u>Solving for time:</u></em>

$Time~taken~to~cover~40~miles~on~local~ roads~= \frac{40}{20} = 2~hours$

$Time~taken~to~cover~180~miles~on~the~highway~=$ $\frac{180}{60}=3~hours$

$Total~Time~=~5~hours$

<em><u>Solving for distance:</u></em>

<em><u /></em> $Total~Distance=40 + 180 = 220$ <em><u /></em>

<em><u /></em>

<em><u>Average speed:</u></em>

<em><u /></em> $\frac{Total~distance}{Total~time} = \frac{225}{5} = 44~miles~per~hour$ <em><u /></em>

Which of the following is true regarding the solution to the logarithmic equation below? log Subscript 2 Baseline (x + 11) = 4.

meriva

Answer:

Option C.

Step-by-step explanation:

The given logarithmic equation is

$\log_2(x+11)=4$

It can be written as

$(x+11)=2^4$ $[\because log_ax=y\Leftrightarrow x=a^y]$

$x+11=16$

$x=5$

Now, to check whether $x=5$ is a true solution or not. Substitute $x=5$ in the LHS of given equation.

$LHS=\log_2(5+11)$

$LHS=\log_2(16)$

$LHS=\log_22^4$

$LHS=4$ $[\because log_aa^x=x]$

$LHS=RHS$

Hence, $x=5$ is a true solution because $\log_2(16)=4$ .

Therefore, the correct option is C.
