In Death Valley, California, the highest ground temperature recorded was 94°C on July 15, 1972. In the formula C= 5/9 (F - 32) ,

gulaghasi [49]

Answer:

$F=201.2\°$

Step-by-step explanation:

we know that

$\°C=\frac{5}{9}[\°F-32]$

For $C=94\°$

substitute in the formula and solve for F

$94=\frac{5}{9}[F-32]$

$(\frac{9}{5})*94=[F-32]$

$F=(\frac{9}{5})*94+32$

$F=201.2\°$

Simplify 12x + 8x - 3x

Pie

when two numbers have the same variable, we can add and subtract just like normal numbers.

12x + 8x = 20x - 3x = 17x

If the circumference is 3/2 pi what is the area

11111nata11111 [884]

Here is your answer

$\frac{9}{16} \pi \: {units}^{2}$

REASON:

Circumference(C)= 2πr

, where r is radius

Given

C= (3/2) π

So,

$2\pi \: r = \frac{3}{2}\pi$

$r = \frac{\frac{3}{2}\pi}{2\pi}$

$r = \frac{3}{4}$

Now,

$area = \pi {r}^{2}$

$= \pi \times { (\frac{3}{4}) }^{2}$

$= \frac{9}{16}\pi \: {unit}^{2}$
