What is the area of the figure:

Mathematics

For this case we have that the area of the triangle is given by:

A = \frac {b * h} {2}

Where:

b: It's the base

h: It's the height

We have to:

cos (45) = \frac {b} {24}\\b = 24 * cos (45)\\b = \frac {\sqrt {2}} {2} * 24\\b = 12 \sqrt {2}

The atura will be given by:

sin (45) = \frac {h} {24}\\h = 24 * sin (45)\\h = \frac {\sqrt {2}} {2} * 24\\h = 12 \sqrt {2}

So, the area is:

A = \frac {12 \sqrt {2} * 12 \sqrt {2}} {2}\\A=\frac{(12\sqrt{2})^2}{2}\\A = 144

Answer:

144

Answer:

Area=144

Step-by-step explanation:

In right triangle ABC,

\sin\left(45^o\right)=\frac{BC}{AB}

\frac{1}{\sqrt{2}}=\frac{BC}{24}

\frac{1}{\sqrt{2}}=\frac{Height}{24}

\frac{24}{\sqrt{2}}=Height

Height=\frac{24}{\sqrt{2}}

similarly

\cos\left(45^o\right)=\frac{AC}{AB}

\frac{1}{\sqrt{2}}=\frac{AC}{24}

\frac{1}{\sqrt{2}}=\frac{Base}{24}

\frac{24}{\sqrt{2}}=Base

Base=\frac{24}{\sqrt{2}}

Then area of right triangle =\frac{1}{2}\left(Base\right)\left(Height\right)

=\frac{1}{2}\left(\frac{24}{\sqrt{2}}\right)\left(\frac{24}{\sqrt{2}}\right)

=\frac{576}{4}=144

Hence Area=144

A map scale is 1 inch:50 miles. Two cities are 450 miles apart. How far apart are the cities on the map
ArbitrLikvidat [17]
450÷50=9
Your answer would be 9inches because all you have to do is divide 450 by 50 and you get the number of inches

An advertising agency notices that approximately 1 in 50 potential buyers of a product sees a given magazine ad, and 1 in 8 sees
zheka24 [161]

Answer:

Probability = 0.12025

Step-by-step explanation:

P (Am) = 1/50 = 0.02       {Magazine ad}

P (At) = 1/8 = 0.125         {Television ad}

P (Am ∩ At ) = 1/100 = 0.01      {Both ads}

P (Am U At) = P (Am) + P (At) - P (Am ∩ At )

= 0.02 + 0.125 - 0.01

P (Am U At)  = 0.135       {Person sees either ad}

P (Am' ∩ At') = 1 - P (Am U At)

P (Am' ∩ At')  = 1 - 0.135 = 0.865      {Person sees none ad}

Prob (Purchase) = Prob (Purchase with ad) + Prob (purchase without ad)

P (P/ A) = 1/4 = 0.25 , P (P / A') = 1/10 = 0.1

P (P) = (0.25) (0.135) + (0.1) (0.865)

= 0.03375 + 0.0865

0.12025

There are 5 chemistry, 6 physics, and 7 math teachers in a school. if 3 teachers are selected randomly, find the probability tha
mrs_skeptik [129]
77.2%

To find the probably and at least on you must find the probability of none and subtract from one.

The probability of none can be found like so:

(5+6 over 5+6+7)^3 = .228

1 - .228 = .772

Hope this helps!
