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.

Answer:
Angle 1 = 46°
Angle 2 = 44°
Step-by-step explanation:
Given:
Angle 1 = (4x - 2)°
Angle 2 = (3x + 8)°
Angle 3 = 90°
Find:
All acute angle
Computation:
Using angle sum property
Angle 1 + Angle 1 + Angle 1 = 180°
(4x - 2)° + (3x + 8)° + 90° = 180°
7x + 6 = 90
7x = 84
x = 12°
So,
Angle 1 = (4x - 2)° = 4(12) - 2 = 46°
Angle 2 = (3x + 8)° = 3(12) + 8 = 44°
Answer:
x = 5, -1
Step-by-step explanation:
0 = 3x^2 - 12x - 15 or
3x^2 - 12x - 15 = 0
By solving for x, use the Quadratic Formula.
… x = 5 and/or -1
