Step-by-step explanation:

The diagonal of a television measures 27 inches. If the width is 22 inches, calculate its height to the nearest inch.

Answers

Answer:

16 inches

Step-by-step explanation:

We can use the Pythagorean theorem to find the height of the television. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two smaller sides is equal to the square of the length of the longest side (the hypotenuse). In this case, the diagonal of the television is the hypotenuse and the width and height are the other two sides.

So, we can set up the equation as follows:

a^2 + b^2 = c^2

where a is the width (22 inches), b is the height, and c is the diagonal (27 inches).

We can solve for b:

b^2 = c^2 - a^2

b^2 = 27^2 - 22^2

b^2 = 729 - 484

b^2 = 245

b = √245

b = 15.56 inches (rounded to two decimal places)

So, the height of the television to the nearest inch is 16 inches.

Answer:

X = 69

Step-by-step explanation:

You add the 11x and 58

Answer: hope this helps ♡      (i wont mind getting brainliest )

x = 3

Step-by-step explanation:

z° and 89° are two opposite angles.

z° = 89°

89° + 89° + (11x + 58)° + (11x + 58)° = 360° (adds up to 360° coz its a circle)

178° + (11x + 58)° + (11x + 58)° = 360°

178° + 58° + 58° + (11x + 11x)° =  360°

178° + 116° + 22x° =  360°

294° + 22x° = 360°

294° - 294° + 22x° = 360° - 294°

22x = 66

22x ÷ 22 = 66 ÷ 22

x = 3

(double check: 11×3 = 33    2×(33+58)+178=360° ✓)

Explain how to determine whether two quantities are proportional.

Answers

Step-by-step explanation: Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

if all of the variables have the same ratio they are proportional

If a value of 60° is added to the data, how does the median change?

Answers

Answer:

The original data set:

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

Finding the median:

77 and 82 are the 2 middle numbers

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

Do 77 + 82 which equals 159

Then do 159 ÷ 2 which would be 79.5

The median for the original data set would be 79.5

Then adding the 60° would make a new data set:

57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

The middle number would be 77

57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

So the median for the second data set would be 77.

Step-by-step explanation:

Hope this helps you a little, you're welcome

Step 1: find the original data set.

57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

77 and 82 are both the middle numbers

Step 2: add the two middle numbers

77 + 82 = 159

Step 3: divide your sum by 2.

159 divided by 2 equals to 79.5

The median for the original data set would be 79.5.




For the new data set, you add 60 to the data set.

Step 1: find the new data set

57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105.

Step 2: find the middle number.

The middle number is 77.

The median for the new data set is 77.

Answers

Answer:

40.5 inches

Step-by-step explanation:

I’m not sure if this is correct or not but my thinking is that you just add 26.9, 8.5, and 5.1 together since it says “How much more snow fell in the one day storm in 2006 than normal falls in February and March combined?” And combined basically means all together.

Answer: 13.3 more inches of snow fell in one day storm than normally falls in February and March combined.

February and March combined: 8.5+5.1 = 13.6

Since the question asked how much more, that means you subtract:

26.9 - 13.6 = 13.3
