Answer:

5/8

Step-by-step explanation:

Would explain but you said as fast as possible.

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

Answer:

t=4/3 or 3/4

Step-by-step explanation:

12t^2-25t+12=0

(3t-4)(4t-3)=0

3t-4=0 or 4t-3=0

t=4/3 or t=3/4

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

Answer:

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.

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]

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.

Step-by-step explanation:

Answer:

2x + 2y = 228

x - y = 40

Step-by-step explanation:

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.

Answer: A

Step-by-step explanation:

I think A because 17x2 is bigger than 17x1, so M<2 is bigger than M<1

Answer:

the second one

Step-by-step explanation:

Answer:

it's c, 80 degrees

Step-by-step explanation:

a triangle is like a straight line, but it has 3 different angles that all add up to 180 degrees

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

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

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°.
