Answer this question so i dont fall victim to a siezure/heart attack from stress

Answers

Answer:

Length = 12 feet, Width = 10 feet

Step-by-step explanation:

Let the length of the bedroom be 'x' ft and the width of the bedroom be 'y' ft.

We know that the perimeter of a rectangle is given by,

P=2(length+width)

P=2(x+y)

It is given that, the length of the bedroom is 2 more than the width, so,

x=y+2

Putting the values in the equation of perimeter we get,

44=2((y+2)+y)

44=2(2y+2)

44/2 =2y+2

22=2y+2

2y=22−2

y= 20/2 =10

Therefore, x=y+2=10+2=12

Hence, the length of the bedroom is 12 feet and the width of the bedroom is 10 feet.

What is the recursive rule for the sequence? -1,-0.5,0,0.5,1,...

Answers

9514 1404 393

Answer:

  C

Step-by-step explanation:

The subscript (n-1) is used to indicate the term previous to term (n). In this sequence, each term is 0.5 more than the previous term, so the recursive relation ...

  [tex]a_n=a_{n-1}+0.5[/tex]

is the appropriate one. This matches choice C.

__

Additional comment

Of course, if the next term is 0.5 more than the last, then the previous term is 0.5 less than the present one. The sequence can be described in this "backward" fashion by the recursive relation of choice A. While that does work to describe the sequence, it is usually not the form we desire for a recursive relation.

The cost of 3 loaves of bread and 3 gallons of milk is $19.35. The cost of 4
loaves of bread and 2 gallons of milk is $17.90. How much does one loaf
of bread cost?

Answers

Answer:

bread $2.5   milk  $3.95

Step-by-step explanation:

b=bread    m= milk

3b +3m = 19.35

4b+2m= 17.90

 Multiply the first by  (-2)

 Multiply the second  by 3

    Then add both

              -6b -6m = -38.7

               12b+6m=53.7

     (when you add both  6m is cancelled)

           6b = 15

         b=  2.5     (BREAD $2.5)

4(2.5) = 10

 10+ 2m = 17.90

2m = 7.90

m= 3.95   (MILK $3.95)

Calculate the percent error

Mr. Boone estimates that it will take him 48 minutes to run 8 miles. It
actually takes him 60 minutes. What was his percent error? *
18%
20%
25%
30%

Answers

Answer:

20%

Step-by-step explanation:

The formula to find percent error is the absolute value of the actual value (60) minus the approximate value (48) divided by the actual value (60) times 100. So first we calculate 60 - 48 which is 12 then divide 12 by 60 which gives us 0.2 and finally multiply by 100 which gives us the answer of 20%
