The average daily high temperature in Madrid peaks at 92°F in the summer and drops as low as 33°F in the winter. The temperature

can be modeled by T (d) = 29.5 cosine (StartFraction 2 pi Over 365 EndFraction (d minus 204) ) + 62.5, where d represents the day number of the year (January 1 is 1, January 2 is 2, and so on). How many days during the year is the high temperature expected to be 75°F or above?

Answer:

C) 131

Step-by-step explanation:

It wants us to find how many days out of the year that the temperature goes above 75 degrees Fahrenheit.

To do this, I set the y value equal to 75 (it should be y\geq 75, but I thought it'd be easier to see this way).

From there, you can easily visualize the days that were above and 75 degrees.

It's just simple subtraction from here:

269-138=131

There are three numbers. The first number is twice the second number. The third number is twice the first number. The sum of the
mel-nik [20]

Answer:

x = 32 y = 16 z = 64

Step-by-step explanation:

x is the 1st number

y is the 2nd number

z is the 3rd number

The first number is twice the second number so

x = 2 y

The third number is twice the first number.

z = 2 x

Their sum is 112

x + y + z = 112

Plus in what we know:

x + y + z = 112

2 y + y + 2x = 112

3y + 2x = 112 Let's solve for y and subtract 2x from each side

3y = 112 - 2x  Divide both sides by 3

y = \frac{112 - 2x}{3}

Now plug our answer back in to solve for x.

x = 2y

x = 2 ( \frac{112 - 2x}{3} )

x = (224 - 4x) / 3    Multiply each side by 3.

3x = 224 - 4x         Add 4x to each side

3x + 4x = 224

7x = 224              Divide each side by 7

7x / 7 = 224 / 7

x = 32

Now we can solve for z.

z = 2x

z = 2 ( 32 )

z = 64

Now we can solve for the numerical value of y.

x + y + z = 112

32 + y + 64 = 112

96 + y = 112       Subtract 96 from each side.

y = 112 - 96

y = 16
