Simplify 12edf – 13def. State a property that you can use.
Answer:
-def. In multiplication, the order doesn't matter.
Step-by-step explanation:
A crucial property you can use to simplify this is the fact that, in multiplication, order doesn't matter.
3 * 2 = 6
2 * 3 = 6
5 * 2 * 3 = 30
2 * 3 * 5 = 30
3 * 2 * 5 = 30
Thus,
edf, or
e * d * f
is the same as def,
d * e * f
e * d * f = d * e * f
edf = def
Thus, 12edf is the same as 12def. We can put this in our expression:
12edf - 13def
12def - 13def
Now, we can see that this will equal -1def or -def
12def - 13def
-1def
-def
Answer: -def. In multiplication, the order doesn't matter.
tan x = -0.25 for 0< x < 720
Answer:
Below in bold.
Step-by-step explanation:
The smallest angle for which -0.25 is the tangent is in the second quadrant and is 165.96 degrees. The other angle in the fourth quadrant is 345.96 degrees.
So for the range 0 to 720, x = 165.96, 345.96 and 360 + 165.96 = 525.96 and 345.96+360 = 705.96 degrees.

6. The amount of time it took four soccer players to run from one goal line to the other is as follows:
Player #1 - 10.4 seconds
Player #2 - 10.1 seconds
Player #3 - 9.9 seconds
Player #4 - 9.4 seconds.
If the data was only accurate to the ones place, which soccer player's time would be different from the others?
A Player #1
B Player #3
C Player #2
D Player #4
Given:
The amount of time it took four soccer players to run from one goal line to the other is:
Player #1 - 10.4 seconds
Player #2 - 10.1 seconds
Player #3 - 9.9 seconds
Player #4 - 9.4 seconds
To find:
Soccer player whose time would be different from the others, if the data was only accurate to the ones place.
Solution:
We need to approximate the time to the ones place.
Player #1 - 10.4 seconds = 10 seconds
Player #2 - 10.1 seconds = 10 seconds
Player #3 - 9.9 seconds = 10 seconds
Player #4 - 9.4 seconds = 9 seconds
Therefore, the time of players 4 is different from others.
Hence, the correct option is D.

At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 calories and twice as many chicken wings as there are sliders. write a system of equations that could be used to determine the number of chicken wings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.
Answer:
x = 2y --------(1)
75x + 250y = 800 ---------(2)
Step-by-step explanation:
Let the number of chicken wings be x
And the number of sliders be y
x = 2y --------(1)
75x + 250y = 800 ---------(2)
The system of equation is x = 2y and 75x + 250y = 800.
Important information:At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 calories and twice as many chicken wings as there are sliders. here we assume the number of chicken wings be x and number of sliders be yEquation:x = 2y --------(1)
75x + 250y = 800 ---------(2)

What is an expression?
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
2x + 4 - 5x is an expression.
3x = 4 is an expression.
We have,
We will find the value of the expression when x = 3.
2x³ = 2 x 3³ = 2 x 3 x 3 x 3 = 64
2x³ + 5 = 2 x 3³ + 4 = 64 + 4 = 68
(2x)³ = 2³ x 3³ = 8 x 27 = 216
(x - 1)³ = (3 - 1)³= 2³ = 8

The momentum of an object, p, is determined by its mass, m, and its velocity, v. The formula p=mv shows this relationship. Which equation shows the formula p=mv correctly solved for v?
A.
v=pm
B.
v=p/m
C.
v=p−m
D.
v=m/p
On solving for [v], we get v = p/m.
What is momentum?Momentum is defined as the product of mass and velocity of a body. Mathematically, we can write vector as -
p = mv
It is a vector quantity. In a three dimensional coordinate, the momentum vector can be resolved as -
[p] = p[x] a[x] + p[y] a[y] + p[z] a[z]
[p] = m {v[x] a[x] + v[y] a[y] + v[z] a[z]}
Given is the momentum of an object whose formula is p=mv.
We have the formula for momentum as -
p = mv
We can solve for [v] as -
p = mv
Divide by [m] on both sides, we get -
p/m = mv/m
v = p/m
Therefore, on solving for [v], we get v = p/m.
