The answer would be x=245 cm


Lyrx [107]3 years ago

Answer:

3.14 cm

Step-by-step explanation:

∆DEG is similar to ∆DFH, so

          DE/DG = DF/DH

         3.0/2.3 = (3.0 + 4.1)/(2.3 + x)

         3.0/2.3 = 7.1/(2.3 + x)     Divide each side by 7.1

         2.3/3.0 = (2.3 + x)/7.1     Multiply each side by 7.1

(2.3 × 7.1)/3.0 = 2.3 + x     Subtract 2.3 from each side

                   x = (2.3 ×7.1)/3.0 – 2.3

                     = 5.443 – 3.0

                     = 3.14 cm

<em>Check: </em>

3.0/2.3 = (3.0 + 4.1)/(2.3 + 3.14)

  1.304 = 7.1 /5.44

  1.304 = 1.305

The numbers check to the nearest hundredth.

Edmond doubled the width of the crate. How do the perimeter and the area of the floor of the new crate compare to those of the o
Mariana [72]

Answer:

The area would be doubled also

The perimeter will be increased in a factor of 1.4

Step-by-step explanation:

Originally the area of new crate = L * B = 1.2 * 0.8 = 0.96 m^2

perimeter is 2(L+ B) = 2(1.2 + 0.8) = 4 m

Now let’s double the width , it becomes 0.8 * 2 = 1.6 m

Area would be 1.6 * 1.2 = 1.92 m^2 which is two times the previous area

The increased perimeter will be 2(1.6 + 1.2) = 5.6 m

This is an increase in factor of 1.4

Miguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, on
jolli1 [7]

Answer:

See explanation

Step-by-step explanation:

<h3 /><h3>Step 1</h3>

Miguel wins $2 is if he pulls two chips with the number 1.  

<u>Probability of winning is: </u>

  • 2/4 * 1/3 = 1/6  as there are 4 chips in total

<u> Probability of loosing is:</u>

  • 1- 1/6 = 5/6
<h3 /><h3>Step 2</h3>

<u>Missing values we found in the step 1, can be populated in the table:</u>

  • Xi === 2 === -1
  • P(Xi) === 1/6 === 5/6

<u>Expected Value as per table data:</u>

  • 1/6*2 + 5/6*(-1) = -1/2

Expected value is $1/2 loss each time he plays

<h3 /><h3>Step 3</h3>

To make the game fair, the expected value should be zero.

<u>Then as per the calculation above, let's replace 2, with x, and find its value.</u>

  • 1/6x + 5/6*(-1) = 0      
  • 1/6x = 5/6                  
  • x= 5  

So the amount should be $5 to make the game fair.
