Line segment JL is an altitude in triangle JKM. Triangle K J M is shown. Angle K J M is a right angle. An altitude is drawn from

point J to point L on side K M to form a right angle. The length of K J is 13, the length of J L is 5, and the length of J M is 8. Which statement explains whether JKM is a right triangle? Round measures to the nearest tenth. JKM is a right triangle because KM = 15.3. JKM is a right triangle because KM = 18.2. JKM is not a right triangle because KM ≠ 15.3. JKM is not a right triangle because KM ≠ 18.2.

Find the length of RA. A. 42 B. 84 C. 14 D. 7

fiasKO [112]

Answer:

$\large \boxed{\mathrm{B. \ 84}}$

Step-by-step explanation:

$LU$ bisects $RU$ and $UA$ .

$RU=UA$

$3m+21=6m$

Solve for m.

Subtract 3m from both sides.

$21=3m$

Divide both sides by 3.

$7=m$

Calculate $RA$ .

$RA=3m+21+6m$

$RA=9m+21$

Put m = 7.

$RA=9(7)+21$

$RA=63+21$

$RA=84$

Answer:

D. $\frac{2}{5}$

Step-by-step explanation:

Since we know that the odds of an events can be found by dividing the probability that an event will occur by the probability that the event will not occur.

$\text{Odds of an event}=\frac{\text{Probability that event will occur}}{\text{Probability that event will not occur}}$

Probability of an event not occurring can be found by subtracting probability of the event occurring from 1.

$\text{Odds of an event}=\frac{\text{Probability that event will occur}}{1-\text{Probability that event will occur} }$

We have been given that probability of an event is 2/7.

Upon substituting our given values in above formula we will get,

$\text{Odds of the given event}=\frac{\frac{2}{7}}{1-\frac{2}{7}} }$

$\text{Odds of the given event}=\frac{\frac{2}{7}}{\frac{7-2}{7}} }$

$\text{Odds of the given event}=\frac{\frac{2}{7}}{\frac{5}{7}} }$

$\text{Odds of the given event}=\frac{2}{7}\times \frac{7}{5}$

$\text{Odds of the given event}=\frac{2}{5}$

Therefore, the odds of the same event are $\frac{2}{5}$ and option D is the correct choice.

Apply the distributive property to write an equivalent expression in factored form: 12s + 18r

Kryger [21]

The most simplified answer is the greatest factor being six. Divide both by six and six is on the outside of parentheses to be equivalent making the answer 6(2s+18r) or -6(-2s-18r) if you used negatives as I would jot down negative and positive

In order to win a quiz contest, olga must score more than 400 points. She earns 12 points for each right answer, and loses 4 poi

Ket [755]

The inequality that represents the number of right answers (r) and wrong answers (w) Olga can give to win the contest is: $3r-w>100$

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

Number of right answers is $r$ and number of wrong answers is $w$

Olga earns 12 points for each right answer and loses 4 points for each wrong answer.

So, total points earned for $r$ right answers $=12r$

and total points lost for $w$ wrong answers $=4w$

That means, <u>her score will be</u>: $(12r-4w)$ points.

In order to win the quiz contest, Olga must score <u>more than 400 points</u>. So, the inequality will be.......

$12r-4w>400\\ \\4(3r-w)>400\\ \\ 3r-w>100$

Which two numbers doesStartRoot 128 EndRoot lie between on a number line? 11. 0 and 11. 1 11. 2 and 11. 3 11. 3 and 11. 4 11. 4

A number line is a representation of a graded straight line. The number √128 will lie between 11.3 and 11.4.

<h3>What is a number line?</h3>

A number line is a representation of a graded straight line that serves as an abstraction for real numbers, which are represented by the letter R. A real number is considered to correspond to every point on a number line, and a point to every real number.

In order to know the location of the √128, we need to write the number √128 in decimal form, therefore, the value of √128 can be written as,

$\sqrt{128} = 11.3137 \approx 11.31$

Now, on the number line if we plot √128 we will see that it will lie between 11.3 and 11.4, as shown below.

Hence, the number √128 will lie between 11.3 and 11.4.
