What is the value of x ?enter your answer as a decimal in the box
maksim [4K]

Answer:

x=67.5\ ft

Step-by-step explanation:

we know that

Triangles MNP and MAB are similar by AAA theorem

If two figures are similar, then the ratio of its corresponding sides is equal

so

\frac{MB}{MP}=\frac{MA}{MN}

substitute the values

\frac{x}{97.5}=\frac{71.5-22}{71.5}

\frac{x}{97.5}=\frac{49.5}{71.5}

x=97.5*\frac{49.5}{71.5}=67.5\ ft

Which is a solution of x2 – x – StartFraction 3 Over 4 EndFraction = 0?
Anna [14]

Answer:

x = - \frac{1}{2}, x = \frac{3}{2}

Step-by-step explanation:

Given

x² - x - \frac{3}{4} = 0 ( add \frac{3}{4} to both sides )

x² - x = \frac{3}{4}

Solve using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2( - \frac{1}{2} )x + \frac{1}{4} = \frac{3}{4} + \frac{1}{4}

(x - \frac{1}{2} )² = 1 ( take the square root of both sides )

x - \frac{1}{2} = ± 1 ( add \frac{1}{2} to both sides )

x = \frac{1}{2} ± 1

Thus

x = \frac{1}{2} - 1 = - \frac{1}{2}

x = \frac{1}{2} + 1 = \frac{3}{2}

What is 1,711,239 rounded to the nearest hundred?
Elina [12.6K]
The hundreds place is filled by a 2.

The number next to it is a 3, which tells how to round. A 3 says 'stay' with the 2. The remaining places after it become zeros.

pav-90 [236]
Well I don't know ! 
Let's take a look and see:

The idea is that there could be more than one way
for a roll of the dice to land with the same number.  

-- If the sum is from 1-4, you get the point.
There are  6  different ways for a roll of the dice to come up 1-4.

-- If the sum is from 5-8, Adam gets the point.
There are  20  different ways for a roll of the dice to come up 5-8.

-- If the sum is 9-12, Lana gets the point.
There are  10  different ways for a roll of the dice to come up 9-12.

-- The game is not fair to all three of you.
-- Lana has a distinct advantage over you.
-- Adam has a big advantage over Lana.
-- Adam has an even bigger advantage over you.
-- You are at a big disadvantage.  (Notice that one of your
numbers ... 1 ... can never come up unless one of the dice
falls off of the table.)
