Answer:

A) x = 9.7

Step-by-step explanation:

Given  : A triangle

To find : What is the value of x to the nearest tenth.

Solution : We have given a triangle with hypotenuse = 12 units,

Opposite side = 7 , adjacent = x.

By the Pythagorean  theorem :

(hypotenuse )² = ( adjacent )² + ( opposite)².

Plug the values

(12)² = ( x )² + ( 7)².

144 =  ( x )² +  49.

On subtracting both sides by 49.

144 -49 =  ( x )²

95 =  ( x )²

Taking square root

√95 = x.

x = 9.7

Therefore, A) x = 9.7

Use the Pythagorean theorem. The equation for this right triangle would be a^2+b^2=c^2. Since you have one leg and the hypotenuse, you can plug these into the equation. It would be 7^2+b^2=12^2. Do the exponents. You will get 49+b^2=144. You need to get b by itself so subtract each side by 49. You get the equation b^2=95. Square root each side to get b=9.746. This rounds to 9.7. So the answer is A. Hope this helps! ;)

What is a negative minus a negative
Rainbow [258]

Answer:

It would be a negative or positive depending on the situation.

Step-by-step explanation:

A negative minus a negative would result in either a positive or negative. For example, -8 - (-9) would be 1 while -8 - (-7) would be -1. If the negative number your subtracting is greater than the number you're subtracting from then it will be positive, vice versa.

The list that orders the fractions from least to greatest is:

  • \frac{7}{12}, \frac{2}{3}, \frac{17}{24}, \frac{3}{4}

<h3>Ordering of fractions</h3>
  • To order the fractions from least to greatest, we have to realize their conversion to decimal.
  • To realize the conversion, the numerator is divided by the denominator, as ordering decimal numbers are easier than fractions.

Hence, the fractions converted to decimal are:

  • \frac{2}{3} = 0.6667.
  • \frac{7}{12} = 0.5833.
  • \frac{17}{24} = 0.7083
  • \frac{3}{4} = 0.75

Hence, the list from least to greatest is, according to the results of the conversions:

  • \frac{7}{12}, \frac{2}{3}, \frac{17}{24}, \frac{3}{4}

You roll two fair dice, a green one and a red one.
olga_2 [115]

Answer:

(a) yes

(b) 1/36

(c) 1/36

(d) 1/18

Step-by-step explanation:

(a) yes they are independent as the outcome of one does not affect the outcome of the other.

(b) As the dice are fair, each possible number (1 through 6) has the same probability of being rolled.

P(1 on green die) = 1/6

P(2 on red die) = 1/6

Therefore, P(1 on green die) AND P(2 on red die) = 1/6 × 1/6 = 1/36

(c) Again, as the dice are fair, each possible number (1 through 6) has the same probability of being rolled.

P(2 on green die) = 1/6

P(1 on red die) = 1/6

Therefore, P(2 on green die) AND P(1 on red die) = 1/6 × 1/6 = 1/36

(d) p[(1 on green die and 2 on red die) OR (2 on green die and 1 on red die)

= 1/36 + 1/36

= 2/36

= 1/18
