Driving to your friend's house, you travel at an average rate of 35 miles per hour. On your way home, you travel at an average r
kenny6666 [7]

<u><em>Answer:</em></u>

14 miles

<u><em>Explanation:</em></u>

<u>The relation that will be used to solve this problem is:</u>

Distance = Velocity*Time

<u>which can be rewritten as:</u>

Time = \frac{Distance}{Velocity}

<u>Assume that:</u>

Distance from your house to your friend's house is d

Time taken from your house to your friend's house is t₁

Time taken from your friends house to your house is t₂

<u>1- From your house to your friend's house:</u>

Average rate = 35 miles/hour

<u>Therefore:</u>

t_{1} = \frac{d}{35}

<u>2- From your friend's house to your house:</u>

Average rate = 40 miles per hour

<u>Therefore:</u>

t_{2} = \frac{d}{40}

<u>3- Round trip:</u>

We know that the round trip took 45 minutes which is equivalent to 0.75 hours

<u>This means that:</u>

t₁ + t₂ = 0.75 hours

\frac{d}{35}+\frac{d}{40}=0.75\\ \\\frac{40d + 35d}{1400}=0.75\\  \\\frac{75d}{1400}=0.75\\  \\ 1050 = 75d\\ d=14 miles

Hope this helps :)

Angle DME and BMQ are equal cause they are opposite angles so you could equate the two to get the value of x. BME is a straight line so after finding the value of the angle BMQ you could do 180-(x+12) = 6y-x-12.

For any positive number b not equal to 1 and any number or variable n, evaluate the following expression.
kirza4 [7]

Answer:

 log_{b} b^{n} = n.

Step-by-step explanation:

Given :  log_{b} b^{n} , b is any positive number not equal to 1 and n is any number.

To find : Evaluate the expression  log_{b} b^{n}.

Formula used : log_{b} x^{y}. = y ∙ log_{b}(x) and

log_{b}(b) = 1.Solution : We have  [tex]log_{b} b^{n}.

By logarithm rule :  log_{b} x^{y}. = y ∙ log_{b}(x).

Then  log_{b} b^{n} = n∙ log_{b}(b).

By logarithm rule :  log_{b}(b) = 1.Now, n∙ [tex]log_{b}(b) = n.

Therefore,  log_{b} b^{n} = n.

Evaluate 38+16 * 12÷2-(30 * 2)
Dvinal [7]

Answer

The answer is 8040

Step-by-step explanation:

It might be wrong, but here take it this way with Pemdas.

P= Parenthesis (30*2) and what's in there is multiplication correct? So, 30 times 2 is 60. Then, E is exponents. There's none there. So we skip to multiplication. 16 times 12 is what? 192. Next is division. So 192 divided by 2. That's 96. So, Then it'd be 38+96(60.) 38+96= 134. 134(60) That being said. That would equal  = 8040  using Multiplication, 194 using addition. 74 using subtraction. And 2.2_ using division.
