Answer:
Planet X is 1.77 times further from Earth than Planet Y.
Step-by-step explanation:
Given that Planet X is 23 of a light-year away from Earth, while Planet Y is 13 of a light-year away from Earth, to determine how much farther away is Planet X the following calculation must be performed:
13 = 1
23 = X
23/13 = X
1.769 = X
Therefore, Planet X is 1.77 times further from Earth than Planet Y.

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°.

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.

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.

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

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]

(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.
