Answer:

9C=5(F-32)

Step-by-step explanation:

The equation which can convert the temperature from degree Celsius into degree Fahrenheit is given as under

9C=5(F-32)

We can solve it further for F as

9C=5F-5 \times 32

9C=5F-160

9C+160=5F

Dividing both sides by 5 we get

\frac{9C}{5}+32=F

F=\frac{9C}{5}+32

Now substituting values of C in this equation will give us the corresponding values of F

Ex : C=1

F=\frac{ 9\times 1}{5}+32

F=\frac{ 9+160}{5}

F=\frac{ 169}{5}

Hence 1 degree Celsius is \frac{ 169}{5} degree Fahrenheit

Nikitich [7]

Answer:

Area of nail's head  = 28.26 millimeter² (Approx.)

Step-by-step explanation:

Given:

Head of nail is circular

Diameter of nail's head = 6 millimeter

Find:

Area of nail's head

Computation:

Radius of nail's head = Diameter / 2

Radius of nail's head = 6 / 2

Radius of nail's head = 3 millimeter

Area of circle = πr²

Area of nail's head  = πr²

Area of nail's head  = (22/7)(3)²

Area of nail's head  = (22/7)(9)

Area of nail's head  = (3.14)(9)

Area of nail's head  = 28.26 millimeter² (Approx.)

7x + 4 = 7x + 4
Kazeer [188]

Infinitely many because if you subtract 7x from both sides, you get 4 = 4, which is true at all times no matter what x is.
