You have probably heard of Albert Einstein's famous formula: E = mc2. While this is an important formula that you may use at som
Gre4nikov [31]

D = S x T  (Distance = Speed x Time)
S = D / T
T = D / S

When I need to drive to a neighboring state for my job, I look on maps
and find out how far away my destination is, and then use this formula
to calculate how long it will take me to get there, how fast I need to drive
in order to get there in the amount of time I have, how far I can get in the
time I have if I drive only at safe and legal speed, and what time I need to
head back in order to get home in time for dinner..

F = 1.8C + 32
C = 0.55 (F - 32)

These are the formulas to convert between Fahrenheit and Celsius expressions
of temperature.  I use them when I'm discussing the weather with my daughter
in Israel, or with my customers almost anywhere outside the USA.

F = M x G
Weight = Mass x Gravity

This formula deals with the relationship between mass and weight.  It's
used when you need to calculate the weight of some particular mass on
some particular planet.  I use it almost every day, when I'm answering
questions in the Physics department on Brainly, and trying to explain
my answers.

Count the possible combinations of 2 letters chosen from L, M, N, O. The possible combinations of 2 letters are __.
Ronch [10]

Answer:

The possible combinations of two letters is 12

Step-by-step explanation:

Here, we want to count the possible combinations of two letters

Now, for the first letter any point in time, we have 4 letters to pick from,

For the second letter we have 3 letters to pick from

So therefore, we have the possible combinations as;

4 * 3 = 12

What is the correct answer for this question ?
maks197457 [2]

Answer:

b)\ 61m

Step-by-step explanation:

The given triangle is a right triangle. This means that one can use right-angle trigonometry to solve the triangle. The right angle trigonometric ratios are a set of ratios that relate the sides and angles of a triangle. These ratios are as follows,

sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}

Bear in mind, the names (opposite) and (adjacent) change depending on the angle of reference. However, the side (hypotenuse) refers to the side opposite the right angle, this side doesn't change depending on the reference angle.

In this problem, one is given the measure of an angle, and the measure of the hypotenuse, the problem asks one to solve for the side opposite the given angle measure. It would make the most logical sense to use the ratio of sine (sin) to do this.

sin(\theta)=\frac{opposite}{hypotenuse}

Substitute,

sin(56)=\frac{h}{73}

Inverse operations,

sin(56)=\frac{h}{73}

73(sin(56))=h

60.519\approx h
