The ratio of the sides of a triangle is 8:13:11. If the perimeter of a triangle is equal to 256, what is the length of the longe

s344n2d4d5 [400]

There asking what the numbers are by The ratios, what I did was did was multiply by 8 for each number 8•8=64 13•8=104 11•8=88 so now what you do is add up 64+104+88=256 those are your answers if you want to double check you will dived them by 8 so 64/8=8 104/8=13 88/8=11
Hope this helps :-)

Given \qquad m \angle LONm∠LONm, angle, L, O, N is a straight angle. \qquad m \angle MON = 8x - 13^\circm∠MON=8x−13 ∘ m, angle,

Tamiku [17]

Answer:

<h3> $\boxed{99°}$ </h3><h3 />

Step-by-step explanation:

m<MON = 8x - 13°

m<LOM = 7x - 17°

To find : m <MON

First, we have to find the value of x :

Create an equation

$\mathrm{8x - 13 + 7x - 17 = 180}$ ( sum of angle in straight line )

Collect like terms

$\mathrm{15x - 13 - 17 = 180}$

Calculate

$\mathrm{15x - 30 = 180}$

Move constant to R.H.S and change its sign

$\mathrm{15x = 180 + 30}$

Calculate the sum

$\mathrm{15x = 210}$

Divide both sides of the equation by 15

$\mathrm{ \frac{15x}{15} = \frac{210}{15} }$

Calculate

$\mathrm{x = 14}$

Now, let's find the value of m<MON

$\mathrm{8x - 13}$

Plug the value of x

$\mathrm{ = 8 \times 14 - 13}$

Calculate the product

$\mathrm{ = 112 - 13}$

Calculate the difference

$\mathrm{ = 99}$ °

Hope I helped!

Best regards!

Your class rank in 2018 was 89 out of 360 students. In 2019 your class rank was 95 out of 450 students. a. In which year did you

spin [16.1K]

A) given that in 2019 you were among the 21.11% of the best students in the class, in that year you had the higher percentile ranking, and B) the measure of average that would be the most meaningful is the median.

Given that your class rank in 2018 was 89 out of 360 students, while in 2019 your class rank was 95 out of 450 students, to determine A) in which year did you have the higher percentile ranking, and B) if you had the data on the cumulative GPA of each student at the end of the spring semester in 2018, which measure of average would be the most meaningful - mean, median or mode -, the following calculation should be performed:

360 = 100
89 = X
89 x 100/360 = X
24.72 = X
450 = 100
95 = X
95 x 100/450 = X
21.11 = X

Therefore, A) given that in 2019 you were among the 21.11% of the best students in the class, in that year you had the higher percentile ranking, and B) the measure of average that would be the most meaningful is the median.

A man who is 2 meters tall is facing a tower that is 13 meters away. He can see the reflection of the top of the tower in a pudd

Vlad [161]

The concept that can be used in order to answer this item is that of ratio and proportion. The ratio of the man's height and the length of his shadow should be proportional or equal to the ratio of the tower height and length of its shadow. If we let x be the height of the tower, the equation that would help us solve this item is,

2 / x = 0.5 / 13.5
The value of x is equal to 54. Thus, the tower's height is approximately 54 meters.
