The temperature in degrees Fahrenheit, F, is related to the temperature in degrees Celsius, C, by the equation
F=9/5 C+32
1.In the Sahara desert, temperatures often reach 50 degrees Celsius. How many degrees Fahrenheit is this?

2.In parts of Alaska, the temperatures can reach -60 degrees Fahrenheit. How many degrees Celsius is this?

3.There is one temperature where the degrees Fahrenheit and degrees Celsius are the same, so that C=F. Use the expression from the equation, where F is expressed in terms of C, to solve for this temperature.

Answers

1 is 122
2 is -51.1111F
3 is F=9/5c+32

The temperatures are in 50° Celsius, -60° Celsius and  -40° Celsius when the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit respectively.

What is the temperature?

Temperature is a measurement of an object or material's warmth or coldness and an expression of thermal energy.

Given, the conversion expression of degrees Fahrenheit to degree Celsius.

The expression is,

F = (9/5)C + 32

For the option 1,

C = 50° Celsius

Then F = 9 x 50/5 + 32

           = 90 +32

           = 122° Fahrenheit

For the option 2,

C = -60° Celsius

Then F =  9 x -60/5 + 32

           = -108 + 32

            = -76° Fahrenheit

For the option 3,

C = F

Then F = 9F / 5 +32

         F - 9F/5 = 32

         -4F / 5 = 32

           F = -160/4

           F = -40° Celsius.

Therefore, the temperatures are 122° Fahrenheit, -76° Fahrenheit and -40° Fahrenheit when the temperatures are in 50° Celsius, -60° Celsius and  -40° Celsius respectively.

The length of a rectangular fenced enclosure is 12 feet more than the width

If farmer Dan has 100 feet of fencing, find the dimensions of the rectangle with the largest perimeter that can be created using 100 feet of fencing.

Answers

length = 31 ft
width = 19 ft


Assume that the width of the rectangle is w.
We are given that the length is 12 ft more than the width. This means that the length of the rectangle is w + 12

The perimeter of the rectangle in this case would be:
perimeter = 2 (length + width)
perimeter = 2 (12 + w + w)
perimeter = 24 + 4w

Assume that Dan would use all 100 ft of fencing to surround the yard. This would mean that the largest perimeter is 100 ft.

Therefore:
perimeter = 24 + 4w
100 = 24 + 4w
4w = 100 - 24
4w = 76
w = 19 ft

Since we have calculated that the width of the yard is 19 ft, we can substitute to get the length as follows:
length = 12 + w
length = 12 + 19
length = 31 ft

Answer:

length = 31 ft

width = 19 ft

A square rug has an inner square in the center. The side length of the inner square is x inches and the width of the outer region is 2 in. What is the area of the outer part of the​ rug?

Answers

Answer:

so Area of Outer part = 8x + 16 square inches

Step-by-step explanation:

2 squares.

inner square dimension is x inches by x inches.

width of outer region= 2inches.

We want the area of the border around the inner square.

so

Area of border = B = Area of Large - Area of Inner

B = (x+4)^2 - x^2

B = x^2 + 8x + 16 - x^2

B = 8x + 16 square inches

so Area of Outer part = 8x + 16 square inches

There no answer because there is a variable next to a number that is being added and you can’t split them

Because there is no sum we can’t find the variable (what R equals) so the answer can only be two things if you are factoring the equation the answer would be 2(R+4). If you are trying to simplify it would remain R2+8.
