Answer: V20

Step-by-step explanation:

Let's go down the list, shall we?

First, V64. I am going to assume that the V is a square root. If you take the square root of 64 you would get 8, which is not an irrational number.

2/2 would be one of the easiest, its just 1 if you simplify it

(16 would be a rational number, even if you took the square root.

4 is four, a rational number

V20 is an Irrational number, again, assuming that the V is a square root symbol, and you took the square root of it, you would get 4.472135955... an infinite number without a pattern

And 5 is just five, a whole number

Answer:

A.

Step-by-step explanation:

the answer is A. because in space, the whole thing is the same amount of density. except for the sun but the question says earth and moon. hop this helps!!! please give me brainliest answer!!!

Quantity A because it changes with gravitational pull.

Given that, the Astronaut's mass of quantity A on earth is 70 units and on the moon is 70 units.

The Astronaut's mass of quantity B on earth is 686 units and on the moon is 112 units.

We can measure weight here on Earth, but not in the microgravity environment on the International Space Station. Mass plays a critical role in the activities and experiments performed by the astronauts. Mass does not change whether it is measured on Earth or the ISS.

Now, mass defines the constitutive matter of an object. It is immutable (does not change). Although it could be converted into energy, the matter is constant.

On the other hand, the weight of an object (gravitational force) depends on the acceleration due to gravity.

That is why an astronaut weighs about three times more on earth than on Mars. The gravitational acceleration on Mars is about one-third that on earth.

Therefore, Quantity A because it changes with gravitational pull.

Answer:

It is the same as ascending order

Step-by-step explanation:

It is the same as ascending order becuase Least is small and Greatest is big so you are going upwards.

Hope This Helps :)

Answer:

Ascedning order

Step-by-step explanation:

Decend typically means "go down", in this case greatest to least goes from the biggest number to the smallest ( go down from biggest to smallest). Ascending means to "rise" or "go up", so to starts at the smallest value ascedning to the biggest value.

least to greatest = ascending

greatest to least = descending

Answer:

4

Step-by-step explanation:

i did math

Answer: 4  

Step-by-step explanation:

The Greatest common factor is the largest factor that both numbers share, so find their factors,

Factors of 20:  1,2,4,5,10 and 20

Factors of 36:  1,2,3,4,6,9,12,18, and 30

The largest factor that both numbers share  is 4

294 gumballs were added because if u subtract 230 from 1696 you get 1466 which was the number you had when you are 230 gumballs so you take 1466 and subtract it from 1760 you get the amount of gumballs that was added.

just like this other lady said 294 gumballs were added

Answer:

11 13 15 17 19

Step-by-step explanation:

We will solve this word problem using 2k+1 which is one of the general forms of an odd integer.

Let 2k+1 be the first odd integer.

(2k+1) + (2k+3) + (2k +5) =  (2k+7) + (2k +9) + 3 (the +3 is to accommodate for the left side being 3 more than the right)

Solve for k

6k + 9 = 4k + 19

6k - 4k + 9 = 4k-4k + 19

2k + 9 = 19

2k + 9 - 9 = 19 - 9

2k = 10

2k/2 = 10/2

k = 5

To get the first digit in the series plug in 5 for k

2k+1

2(5) + 1

10 + 1 = 11

So our series is 11, 13, 15, 17, 19

Let's test it.

11 + 13 +15 = 39

17 + 19 = 36

So we are correct, the first 3 integers are 3 more that the sum of the last 2.

11, 13, 15, 17, 19

I am doing this in my RSM homework, just saying this is correct. I guessed and checked to do this.

Answer:

Step-by-step explanation:

Let |x-a|=b

then x-a=±b

so x-a=b

or x=a+b

so a+b=18   ...(1)

and x-a=-b

or x=a-b

or a-b=8   ...(2)

adding (1) and (2)

2a=26

a=26/2=13

subtract (2) from (1)

2b=10

b=10/2=5

|x-13|=5

Answer:

9

Step-by-step explanation:

We are given the expression:

[tex]5w+1p[/tex]

and asked to evaluate for w=3 and p= -6. Therefore, we must substitute 3 in for w and -6 in for p.

[tex]5(3)+1(-6)[/tex]

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

Multiply 5 and 3.

⇒ 5*3=15

[tex]15+1(-6)[/tex]

Multiply 1 and -6.

⇒1*-6= -6

[tex]15 + -6[/tex]

Add 15 and -6.

⇒ 15 + -6= 15-6= 9

[tex]9\\[/tex]

The expression 5w+1p when evaluated for w=3 and p= -6 is 9

Answer:

Step-by-step explanation:

(5x³)(4x³) = 20x^6

Answer:

B and D

Step-by-step explanation:

B:

Anything to a negative power means that it is 1/that to the positive power.

E.g. x^-1 = 1/x^1

In other words, anything to the power of a negative switches sides of a fraction (i.e. if in numerator moves to denominator and vice versa.)

1/x^-1 = 1/1/x^1 which is just equal to x, because there are x number of 1/xs in one (1/x * x =1) Therefore Option B is equal to just x.

D: (assuming the first given term is x^1/3 and not X1/3 (?) Correct me if I'm wrong).

x^1/3 * x^1/3 * x^1/3 is also equal to just x.

This is because when multiplying together terms with the same base (x in this case) the exponents just add together, so:

x^1/3 * x^1/3 * x^1/3 = x^(1/3 +1/3 +1/3) = x^1 = x.

Therefore B and D are equivalent because they both equal x.

Answer:

Time=2800 seconds.

Time in minutes= 46.67 minutes

Time in hours= 0.778 hours

Step-by-step explanation:

Distance traveled= 70000 m

Rate or speed of travel= 25m/s

To calculate the time for the travel, we multiply the rate of travel by the distance covered or traveled.

Rate= distance/time

Time= distance/rate

Time= 70000/25

Time=2800 seconds.

Time in minutes= 2800/60

Time in minutes= 46.67 minutes

Time in hours = 2800/(60*60)

Time in hours= 2800/360

Time in hours= 0.778 hours

Answer:

The answer is "[tex]\bold{\left[\begin{array}{cc}a&b\\c&d\end{array}\right] = \left[\begin{array}{cc}7&-2\\ -\frac{1}{2}&\frac{7}{2}\end{array}\right]}[/tex]".

Step-by-step explanation:

[tex]\bold{\left[\begin{array}{cc}1&2\\3&4\end{array}\right] \left[\begin{array}{cc}a&b\\c&d\end{array}\right] = \left[\begin{array}{cc}6&5\\ 19&8\end{array}\right]}[/tex]

Solve the L.H.S part:

[tex]\left[\begin{array}{cc}1&2\\3&4\end{array}\right] \left[\begin{array}{cc}a&b\\c&d\end{array}\right]\\\\\\\left[\begin{array}{cc}a+2c&b+2d\\3a+4c&3b+4d\end{array}\right][/tex]

After calculating the L.H.S part compare the value with R.H.S:

[tex]\left[\begin{array}{cc}a+2c&b+2d\\3a+4c&3b+4d\end{array}\right]= \left[\begin{array}{cc}6&5\\ 19&8\end{array}\right]} \\\\[/tex]

[tex]\to a+2c =6....(i)\\\\\to b+2d =5....(ii)\\\\\to 3a+4c =19....(iii)\\\\\to 3b+4d = 8 ....(iv)\\\\[/tex]

In equation (i) multiply by 3 and subtract by equation (iii):

[tex]\to 3a+6c=18\\\to 3a+4c=19\\\\\text{subtract}... \\\\\to 2c = -1\\\\\to c= - \frac{1}{2}[/tex]

put the value of c in equation (i):

[tex]\to a+ 2 (- \frac{1}{2})=6\\\\\to a- 2 \times \frac{1}{2}=6\\\\\to a- 1=6\\\\\to a =6 +1\\\\\to a = 7\\[/tex]

In equation (ii) multiply by 3 then subtract by equation (iv):

[tex]\to 3b+6d=15\\\to 3b+4d=8\\\\\text{subtract...}\\\\\to 2d = 7\\\\\to d= \frac{7}{2}\\[/tex]

put the value of d in equation (iv):

[tex]\to 3b+4 (\frac{7}{2})=8\\\\\to 3b+4 \times \frac{7}{2}=8\\\\\to 3b+14=8\\\\\to 3b =8-14\\\\\to 3b = -6\\\\\to b= \frac{-6}{3}\\\\\to b= -2[/tex]

The final answer is "[tex]\bold{\left[\begin{array}{cc}a&b\\c&d\end{array}\right] = \left[\begin{array}{cc}7&-2\\ -\frac{1}{2}&\frac{7}{2}\end{array}\right]}[/tex]".
