Geometry question on finding x.

Dmitrij [34]

Answer:

$x =63^o$

Step-by-step explanation:

Given :-

$\text{ $\overline{MN} $ and $\overline{ML}$ are tangents .}$

We know that the tangents are perpendicular to the radius at the point of contact . And here OLMN is a quadrilateral. Also we know that , the angle sum property a triangle is 360° .

According to question :-

$\implies x + 117^o + 90^o +90^o = 360^o \\\\\implies x + 297^o = 360^o \\\\\implies x = 360^o - 297^o \\\\\implies x = 63^o$

Hence the value of x is 63° .

Crickets can jump with a vertical velocity of up to 14 ft/s. Which equation models the height of such a jump, in feet, after t s

Y_Kistochka [10]

Answer:

h = 147 - 16t^2.

Step-by-step explanation:

Use the following equation of motion

h = ut + 1/2 gt^2 where h = height, u = initial velocity , g = acceleration due to gravity and t = the time.

So here we have:

h = 14t + 1/2 * -32 * t^2

h = 14t - 16t^2

The sum of two numbers is 80 . The ratio of those two numbers is 3:5 find the larger Number

Oksana_A [137]

Answer:

the larger number is 50

Step-by-step explanation:

Notice there are two unknown numbers. Let's address the smaller one as x and the larger one as y. now we can write two equations from translating the phrases given into algebraic expressions:

"the sum of two numbers is 80" can be written as:

$x+y=80$

Now the second phrase:

"The ratio of those two numbers is 3/5"

Notice here that in our ratio we need to use our small number (x) in the numerator of the quotient, and the larger number (y) in the denominator to make it in agreement with the small and larger numbers of the ratio $\frac{3}{5}$ , and solve for x:

$\frac{x}{y} = \frac{3}{5} \\x= \frac{3}{5}y$

Replace the value of x we just obtained in the first equation we wrote, so we obtain one equation with only one unknown hat we should be able to solve:

$x+y=80\\\frac{3}{5} y+y=80\\\frac{3}{5} y+\frac{5}{5} y=80\\\frac{8}{5}y=80 \\8y=80*5\\8y=400\\y=\frac{400}{8} \\y=50$

Therefore the larger number (y) equals 50.

What is the difference between experimental and nonexperimental methods of study? Nonexperimental methods involve operational de

Anon25 [30]

Experimental methods involve the manipulation and control of variables, whereas non experimental methods require simple observation of the variables.

Answer: Option D.

Explanation:

Non-experimental research about doesn't mean nonscientific. Non-experimental investigate implies there is an indicator variable or gathering of subjects that can't be controlled by the experimenter. Test plan, then again, takes into consideration specialists to control the indicator variable and subjects.

Non experimental research falls into three broad categories: single-variable research, correlational and quasi-experimental research, and qualitative research.
