Answer:

The fuel economy is 36 miles per gallon. For each mile 1/36 gallon will be used.

Initial volume is 13,2 gallons and x is the number of miles.

<u>Our equation is:</u>

y = 13.2 - 1/36x

y = -1/36x + 13.2

STANDARD FORM:

y = mx + b, where m is slope and b is y-intercept.

ANSWER:

For one mile, it takes 1/36 gallons and first it has 13.2 gallons in it.

Let the no of miles be x.

So, equation becomes

y = - 1/36x + 13.2

You flip a fair coin until you see three tails in a row. What is the average number of headsthat you’ll see until gettingTTT?

Verdich [7]

Answer:

Step-by-step explanation:

From the given information:

suppose, Y is the number of times a coin is being flipped.

If the coin is flipped for the first time and we get H, then we have:

TTT = $\dfrac{1}{2}(Y+1)$

Afterward, if we get H, then we waste two times plus the probability of this event $\dfrac{1}{4}$ .

Therefore, we have : $\dfrac{1}{4}(Y+2)$

Afterward, if we get H, then we waste three times plus the probability of this event $\dfrac{1}{8}$ .

Therefore, we have : $\dfrac{1}{8}(Y+3)$

If we got T at the third time, then;

T = $\dfrac{1}{8}(3)$

Thus, average number of headsthat you’ll see until gettingTTT can be expressed as:

$= \dfrac{1}{2}(Y+1)+ \dfrac{1}{4}(Y+2)+ \dfrac{1}{8}(Y+3)+ \dfrac{1}{8}(3)$

= 14

Jk is perpendicular to xy at its midpoint m. choose the answer that includes the correct responses.

Soloha48 [4]

Answer:

Step-by-step explanation:

JK intercept line XY at the midpoint. This means that these points are all equidistant from the midpoint. Due to this, J and K are both an equal distance from M. So is X and Y.

Overline MD cong overline LS additional information is necessary to show that triangle MTD cong triangle LGS by SSS?

aivan3 [116]

Answer:

$TD \cong GS$

Step-by-step explanation:

See comment for complete question

Given:

$TM \cong GL$

$MD \cong LS$

Required

The information that shows $\triangle MTD \cong \triangle LGS$ by SSS

By SSS implies that, the three sides of both triangles are congruent

Already, we have:

$TM \cong GL$

$MD \cong LS$

The third side of $\triangle MTD$ is $TD$

The third side of $\triangle LGS$ is $GS$

So, for both to be congruent by SSS, the third sides must be congruent

i.e.

$TD \cong GS$

Is the function even odd or neither?

Mandarinka [93]

The answer is the first option: Even.

The explanation for this exercise is shown below:

1. By definition, if $f(x)=f(-x)$ the fucntion is even.

2. When the graph is symmetric with respect to the y-axis, it is an even function.

3. As you you can see in the graph attached in the problem, the graph is symmetric about the y-axis. Therefore, you can conclude it is an even function.

13) What is the simple interest and total amount earned on $4345 with an interest rate of

Annette [7]

Answer:

173.80 interest, 4518.80 total

Step-by-step explanation:

4345 X .03(3%)=130.35/year

130.35/12=10.8625/month

10.8625 x 16 months = 173.80 interest over 16 months

4345+173.80=4518.80 total amount
