Answer:

x = 39

Step-by-step explanation:

The sum of all three angles of a triangle will ALWAYS be 180 degrees.

So, simply subtract 39 and 103 from 180 and you will find your answer.

180 - 39 - 102 = 39

How to write the ratio of the amount of time spent playing video games to the amount of time spent watching television

Pavlova-9 [17]

You can write it just as given:

... (time spent in video games)/(time spent in television) = (10 minutes)/(1 hour)

However, the intent is to end with a pure number (no units), so we need to convert hours to minutes or vice versa. Most folks know that 1 hour is 60 minutes, so that is probably the easier conversion.

... = (10 minutes)/(60 minutes)

... = 10/60 . . . . . . . . . the units in numerator and denominator are the same, so cancel

... = 1/6 . . . . . . . . . . . .the fraction is reduced in the usual way

The ratio in simplest form is 1/6.

The perimeter of a square must be greater than 102 inches but less than 138 inches. Find the range of possible side lengths that

liberstina [14]

Answer:

s ∈ (25.5,34.5)

''s'' is in inches unit

s ∈ IR

Step-by-step explanation:

We know that the perimeter of a square is $P=4s$

Where P is the perimeter and s is the length of a side.

We want the perimeter to be greater than 102 inches but less than 138 inches.

We can write :

102 inches < P < 138 inches

If we replace P = 4s in the expression :

102 inches < 4s < 138 inches

Dividing by ''4''

25.5 inches < s < 34.5 inches

If we want the perimeter to be greater than 102 inches but less than 138 inches the length of a side must be greater than 25.5 inches but less than 34.5 inches.

Writing this in interval notation

s ∈ (25.5,34.5)

s ∈ IR
