2 answers:

6 0

Answer=C

The conversion formula between Celsius and Fahrenheit is:

°F=(9/5*°C)+32

Based on the information given, we know that °C=30. So we can solve for °F.

°F=(9/5*°C)+32
°F=(9/5*30)+32
°F=(54)+32
°F=86

30 Degrees Celcius is equivalent to 86 degrees Fahrenheit.

If a thermometer indicates 30 degrees Celsius, the temperature in degrees Fahrenheit is 86°F.

Boiling water measures 100 degrees in Celsius, and 212 degrees in Fahrenheit. Freezing water measure 0 degrees in Celsius, and 32 degrees in Fahrenheit.

So, if you want to convert Celsius into Fahrenheit, you will need to:
Multiply by 180/100
Add 32

Let's convert 30 degrees Celsius into Fahrenheit.
30 180/100 = 54
54 + 32 = 86

To estimate the length of the lake, caleb starts at one end of the lake and walk 95m. He then turns a 60° angle and walks on a n

aivan3 [116]

Answer:

Length of the lake is 97.30 m

Step-by-step explanation:

We have given Caleb starts at one end of the lake and walk 95 m

So $d_1=95m$

And then he turns at an angle of 60°

So $\Theta =60^{\circ}$ and then again walk 8 m

So $d_2=8m$

We have to fond the total length of the lake , that is d

Total length of the lake is given by $d=\sqrt{d_1^2+d_2^2+2d_1d_2cos\Theta }=\sqrt{95^2+8^2+2\times 95\times 8\times cos60^{\circ}}=97.30m$

So length of the lake is 97.30 m

Each angles of an equilateral traingle is 60, proove it experimentally

MArishka [77]

Answer:

True

Step-by-step explanation:

We knwo this is true because a triangle angle theorem is that the sum of the angles in a triangle is equal to 180 degrees.

Since tri = 3 then,

=> 180/3 = 60

Equal = same --> def. of equilateral triangle

Thus, we know it is true that in an equilateral triangle, each angle is 60 degrees

Hope this helps!

A sphere has a surface area of 36 pi. find the volume of the sphere

Vesna [10]

V ≈ 20.31

$V= \frac{A^{3/2} }{6 \sqrt{ \pi } } = \frac{36^{3/2} }{6 \sqrt{ \pi } } = 20.31083$

Write the expression in standard form. 2/2-15i

nlexa [21]

Standard form is a+bi

so get rid of that deonmenator

$\frac{2}{2-15i}$
multiply it by $\frac{2+15i}{2+15i}$
result is
$\frac{4+30i}{4+225} = \frac{4+30i}{229}= \frac{4}{229} + \frac{30i}{229}$

answer is $\frac{4}{229} + \frac{30i}{229}$
