HELPPP PLEASEEEEEE!?!?!

Mathematics
1 answer:
DiKsa [7]3 years ago
6 0

a straight line is 180 degrees so we can find C by subtracting 140 from 180

180-140 = 40 degrees

all 3 inside angles need to equal 180 so now we have

180 = 40 + (2x) + (x+2)

180 =  40 +3x +2

180=42+3x

138=3x

x= 138/3 = 46


 check : 2x= 2*46 = 92

x+2 = 46+2 = 48

92 +48 +40 = 180

 so x = 46 degrees

 so angle B = 2x46 = 92 degrees

Suppose you select 2 letters at random from the word compute without replacement. Find each probability. P(2 vowels)
Troyanec [42]

Answer:

1/7

Step-by-step explanation:

The word "compute" has 7 letters, 3 of which are vowels.

The probability that the first letter is a vowel is 3/7.

There's no replacement, so there are 6 letters left, 2 of which are vowels.

The probability that the second letter is a vowel is 2/6.

The probability of 2 vowels is therefore:

P = (3/7) (2/6)

P = 1/7

The width of a rectangle is 7 meters greater than its length. If the area of the rectangle is 170 square meters, write the quadr
Lostsunrise [7]
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
  x(x +7) = 170
In standard form, the quadratic is ...
  x² +7x -170 = 0

A combination lock uses three numbers between 1 and 46 with​ repetition, and they must be selected in the correct sequence. Is t
vladimir2022 [97]

The correct answer is D. ​No because the permutations rule would be used to determine the total number of combinations.

Explanation:

The difference between a combination and a permutation is that in permutations the order is considered. This applies to the numbers in a lock because these need to be in order. Therefore, to analyze the permutations in a lock, the rule for permutations should be used. This includes the general formula P (n,r) =\frac{n!}{(n-r) !}; in this, n is the number of objects and r refers to the objects used in a permutation. Thus, the term "combination" is inappropriate because this is a permutation, and the permutation rule should be used.
