Compute 6^(-4) divided by 3^(-4).
GIVE YOUR ANSWER AS A FRACTION!
Answer:
6^-4 ÷ 3^-4
6^-4/3^-4
Since their powers are negative
Flip them both so the negative index is lost.
It now becomes
3^4/6^4
81/1296
=1/16

La medida de cada ángulo interno de un polígono regular es 140o. Determine la medida de cada ángulo central.
Answer:
Cada ángulo central tiene una medida de 40°.
Step-by-step explanation:
Un ángulo interno en un polígono regular comprende dos ángulos contiguos de igual medida de dos triángulos contiguos. Si el polígono regular tiene un ángulo interno de 140°, entonces cada triángulo tiene dos ángulos de 70°. El tercer ángulo corresponde al ángulo central. Por Geometría sabemos que la suma de las medidas de los ángulos internos de un triángulo es igual a 180°, entonces tenemos que la medida del ángulo central es:
[tex]\alpha = 180^{\circ} - 70^{\circ} - 70^{\circ}[/tex]
[tex]\alpha = 40^{\circ}[/tex]
Cada ángulo central tiene una medida de 40°.
(1 point) Find ⋅ if =⟨−1,0,1⟩ and =⟨4,5,2⟩ Is the angle between the vectors "acute", "obtuse" or "right"?
Answer:
Obtuse.
Step-by-step explanation:
If we have a vector v = (a, b, c)
The magnitude of the vector is:
|v| = √(a^2 + b^2 + c^2)
And the dot product of two vectors:
v = (a, b, c)
w = (c, d, e)
is:
v.w = |v|*|w|*cos(θ) = a*c + b*d + c*e
With that relation, we can find the angle between the two vectors.
In this case, we have:
v = ⟨−1,0,1⟩
then:
|v| = √( (-1)^2 + 0^2 + 1^2) = √2
And:
w = ⟨4,5,2⟩
then:
|w| = √( 4^2 + 5^2 +2^2) = √116
Then:
v.w = (√2)*(√116)*cos(θ) = (-1)*(4) + 0*5 + 1*2
(√2)*(√116)*cos(θ) = -4 + 2 = -2
(15.23)*cos(θ) = -2
cos(θ) = -2/15.23
θ = Acos( -2/15.23) = 97.5°
Then the angle is larger than 90°, so the angle is obtuse.

I need help please
Answer:
480
Step-by-step explanation:
Substitute in the numbers for your letters, the length being 4, width being 10 and height being 12. To make things easier, multiply 10 by 12 which gets you 120. Then multiply 120 by 4 and you get 480.

ASAP "PLEASE HELP"Farah rolled a number cube 84 times. The outcome of "2" occurred 12 times. What is the experimental probability of rolling 2. Write your answer as fraction in simplest form. Please I only have 1 hour left
Answer: [tex]\dfrac{1}{7}[/tex]
Step-by-step explanation:
Given
A cube is rolled 84 times
2 occurred 12 times
Experimental probability is determined by the use of data obtained in the experiment.
Therefore, the experimental probability of obtaining 2 on 84 rolls of the die is
[tex]\Rightarrow P=\dfrac{12}{84}\\\\\Rightarrow P=\dfrac{1}{7}[/tex]

How do you find the radius of a Tetrahedron?
My own question no answer choices.
No bit links plz. 15 points and plz describe well.
Answer:
The center of the tetrahedron divides each of the four heights (or medians) in the ratio 1:3 (in an equilateral triangle the corresponding ratio is 1:2). The smaller part is also the radius of the inscribed sphere. Therefore the radius of this sphere is one quarter of the height or 9 in your case.
How to solve this. I am very confused.
To solve, we will need to plug in -5 for x in both instances.
|-5 + 2| / -5 + 2
|-3| / -3
Now, these absolute value bars may be a bit puzzling. What we have to do is take the absolute value of the number inside of the brackets. Meaning, that if the number is negative, we make it positive, and if the number is positive, then it stays positive.
3 / -3
-1
Hope this helps!! :)
Answer:
-1
Step-by-step explanation:
Plug in the value for x (-5) into the equation: [tex]\frac{|(-5)+2|}{(-5)+2}[/tex]
Simplify:[tex]\frac{|-3|}{-3}[/tex]
Take absaloute value to simplify further:
(All absaloute value means (which is what these bars represent: | |) is how far away a number is from zero, so the number will always be its positive counterpart if it is not already positive):
[tex]\frac{3}{-3}[/tex]
Now simplify (divide 3 by -3) to get your answer:
-1

Liz walks 1/2 mile in 20 minutes on Monday and 3 3/4 in 150 minutes on Sunday is this proportional or non -proportional
Answer:
proportional
Step-by-step explanation:
so if 1/2 is 20, 1/4 is 10, and 1 whole mile is 40.
40 + 40 + 40 + 10 + 10 + 10 = 150
because we used the reasoning from the first part and it turned out correct, it is proportional

At a football game, a vender sold a combined total of 208 sodas and hot dogs. The number of hot dogs sold was 44 less than the number of sodas sold. Find the number of sodas sold and the number of hot dogs sold.
Answer:
the number of sodas sold and the number of hot dogs sold is 126 and 82 respectively
Step-by-step explanation:
Given that
The total of sodas and hot dogs sold is 208 sodas
And, the number of hot dogs was 44 less than the number of sodas sold
We need to find out the number of sodas sold and the number of hot dogs sold
Let us assume the number of sodas sold be x
So, the number of hot dogs be x - 44
Now as per the given question
x + x - 44 = 208
2x = 208 + 44
2x = 252
x = 126
So, the number of hot dogs is
= 126 - 44
= 82
hence, the number of sodas sold and the number of hot dogs sold is 126 and 82 respectively
