Given the two similar triangles below, which proportion is not true?
weqwewe [10]

The proportion of sides of the triangle which is not true are 13.5/21 = 9/14, 9/13.5 = 6/21 and 14/6 = 21/9

<h3>Proportion</h3>

The three sides of each of the rectangles should be proportional to each other

Triangle A : Triangle B

9 cm : 13.5 cm

= 9/13.5

14 cm : 21 cm

= 14 cm / 21 cm

6 cm : 9 cm

= 6 cm / 9 cm

Therefore, the proportion of sides of the triangle which is not true are 13.5/21 = 9/14, 9/13.5 = 6/21 and 14/6 = 21/9

What is 20 - 15 x 2026 - 265 + 125
s344n2d4d5 [400]

Hey there!

Do PEMDAS to solve.

PEMDAS simply means….

• Parentheses
• Exponents
• Multiplication
• Division
• Addition
• Subtraction
~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~|~

20 - 15 * 2026 - 265 + 125

≈ 20 - 30,390 - 265 + 125

≈ -30,370 - 265 + 125

≈ -30,635 + 125

≈ −30,510


Therefore, your answer is: -30,510


Good luck on your assignment & enjoy your day!

Zepler [3.9K]

Answer: 8/145

Step-by-step explanation: Rewriting the table

Positive and Negative stand for the result of the test

Yes and No stand for having the disease

          Positive       |      Negative     | Total

<u>Yes </u><u>  |     137           |             8           |   145</u>

<u>No  </u><u>  |       16           |            139        |    155</u>

<u>Total</u><u> |     153           |            147        |   300</u>

<u />

probability of getting someone who tests negative, given that he or she had the disease.

P(Negative | Yes) = <u>P(Negative ∩ Yes)</u> = <u> 8 </u>

                                        P(Yes)              145

Identify the translation rule on a coordinate plane that verifies that triangle A(-5,1), B(-2,7), C(0,1) and triangle A'(-3,2),
alexira [117]
The answer is B
first, look at all the x coordinates:
-5+2=-3, -2+2=0, 0+2=2
then, look at all the y coordinates:
1+1=2, 7+1=8, 1+1=2

All the three points are translated in the same way, that is, right 2 units, up 1 unit. the two triangles are congruent.
