Answer:

The 51 and 62 triangle is 67°

The 43 triangle is 47°

Step-by-step explanation:

Angles in a triangle add to 180°

180 - ( 51 + 62 ) = 180 - ( 113 ) = 67°

180 - ( 43 + 90 ) = 180 - 133 = 47°

In 1980, the average monthly rate for basic able TV in the United States was
poizon [28]

The average rate of change in the monthly rate per year is -$0.056 i.e decreases by 0.056 every consecutive year.

Step-by-step explanation:

Step 1; The initial value is $7.69 in 1980 and the final value is $6.13 in 2008.

Difference in values = Final value - initial value = $6.13- $7.69 = -$1.56 (the negative symbol indicates that the cost has gone down with time)

Period between the values =Final year - initial year = 2008 - 1980 = 28 years.

Step 2; To find the rate of change per year, we divide the difference in values in that given period of time by the number of years in that period.

Rate of change per year = Difference in values in that period/ no of years.

                                          = -$1.56 / 28 = -$0.056 (the negative symbol indicates that the cost has gone down with time)

So for every year between 1980 and 2008, the price of the monthly rate for basic able TV reduced by $0.056.

Stells [14]

Answer:

\huge\boxed{width=12cm}

Step-by-step explanation:

l-length\\w-width\\P-perimeter

The formula of perimeter of the rectangle:

P=2l+2w=2(l+w)

Substitute:

l=6w\\\\P=168cm

168=2(6w+w)\\168=2(7w)\\168=14w\qquad|\text{divide both sides by 14}\\\\\dfrac{168}{14}=\dfrac{14w}{14}\\\\12=w\Rightarrow w=12(cm)

A number is selected at random from the set {2, 3, 4,. 10}. Which event, by definition, covers the entire sample space of this e
Citrus2011 [14]

The event by definition that covers the entire sample space of the experiment is;

<em><u>The number is even or less than 12</u></em>

We are given the numbers in the set as;

set {2, 3, 4,... 10}.

Now, the numbers in the set are even and odd numbers from 2 to 10 with 10 being the highest and 2 being the lowest.

Thus the event that covers this sample space is simply a set of numbers that are even or less than 12.
