Help!!!! This is geometry, the picture has the question!

skad [1K]

Answer:

LN = 16

Step-by-step explanation:

MO bisects LN into two equal parts (If you see a triangle MNL, the line in the middle 5y - 8 is a median. This means x + 6 = 4x)

x + 6 = 4x

3x = 6

x = 2

Substitute x

LN = 2 + 6 + 8 = 16

LN = 16

Hope this helps :)

Have a nice day!

Do the ratios 2/1 and 16/8 form a proportion?

satela [25.4K]

Answer:

David drops a soccer ball off a building. The building is 75 meters tall.

Nezavi [6.7K]

a) 70.1 m

The ball is moving by uniformly accelerated motion, with constant acceleration $g=9.8 m/s^2$ (acceleration due to gravity) towards the ground. The height of the ball at time t is given by the equation

$h(t)=h_0 - \frac{1}{2}gt^2$

where $h_0 = 75 m$ is the height of the ball at time t=0. Substituting t=1 s, we can find the height of the ball 1 seconds after it has been dropped:

$h(1 s)=75 m - \frac{1}{2}(9.8 m/s^2)(1 s)^2=70.1 m$

b) 3.9 s

We can still use the same equation we used in the previous part of the problem:

$h(t)=h_0 - \frac{1}{2}gt^2$

This time, we want to find the time t at which the ball hits the ground, which means the time t at which h(t)=0. So we have

$0=h_0 - \frac{1}{2}gt^2$

And solving for t we find

$t=\sqrt{\frac{2h_0}{g}}=\sqrt{\frac{2(75 m)}{9.8 m/s^2}}=3.9 s$

In 2015, nearly seven out of every ten autos sold in a country was a crossover utility vehicle (CUV). If an auto dealership sold

Over [174]

Answer:

2,800 CUV cars were sold

Step-by-step explanation:

7 out of 10 are CUV

Total sold are 4,000

Set them equal to each other:

$\frac{7}{10} = \frac{x}{4000}$

Cross multiply:

$7 * 4,000 = 10*x$

$28,000=10x$

Solve for x:

$\frac{10x}{10} =\frac{28,000}{10}$

x = 2,800
