let x and y be numbers, y ≠ 0 and let n be a positive integer. How is (x/y)^n related to x^n and y^n?

Answer:

10

Step-by-step explanation:

Let A = set of numbers from 1 - 10

A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

Let B = subset of A which are even numbers

B = {2, 4, 6, 8, 10}

Let C = subset of A which are multiples of 5

C = {10}

which elements are in both the subset of even numbers, and the subset of multiples of 5:

AnB means elements which appears in both set B and C

BnC = {5}

Answer:

36

Step-by-step explanation:

To find the average of a series of numbers, add them together and then divide by the count of numbers, i.e., 4.

(35 + 27 + 54 + 28) / 4 = 36

Answer:

answer is 36

Step-by-step explanation:

for finding average we have to add all the numbers and by dividing that by the total number present we can get the average

so there are 4 numbers

average= 35+27+54+28/ 4

or 144/4= 36 (ans)

Wednesday: 45 - 18

Thursday: 55 - 22

Step-by-step explanation:

18*2.5=45

55/5=11

11*2=22

Answer:

Trees Planted Unknown Value = 45

Trees Harvested Unknown Value = 22

Step-by-step explanation:

Plants : Harvest

= 5 : 2

= x : 18

= 5 * x : 2 * x

= 5 * x : 18 / 2

= 5 * x : 9

= 5 * x : x

= 5 * x : 2 * x

= 5 * 9 : 2 * 9

= 45 : 18

Trees planted value  = 45

Plants : Harvest

= 5 : 2

= 55 : y

= 5 * y : 2 * y

= 55 / 5 : 2 * y

= 11 : 2 * y

= y :  2 * y

= 5 * y : 2 * y

= 5 * 11 : 2 * 11

= 55 : 22

Trees harvested value  = 22

Answer:

b. The paint will not fill the tray by 5.22 in3.

Step-by-step explanation:

The computation is shown below:

First we have to determine the volume of tray by using the following equation

[tex]V = L \times W \times H[/tex]

Now transform this from dimensions to inches

Now  putting the values,

[tex]V = 10\times12\times (5\times(\frac{1}{2.54})) \\\\As\ 5 cm = 5 \times (\frac{1}{2.54})[/tex]

the volume would be equivalent to the

236.22 inches^3

Now 1 gallon is 231 inches^3

So, the remaining would be

= 236.22 - 231

= 5.22^3

Therefore the correct option is b.

Hence, all the other options are wrong

Answer: No

Step-by-step explanation: no because one is negative 1 3/4 and the other one isint in the negatives

The sum of -1 3/4 and 2 1/2 is the same as the difference between 2 1/2 and 1 3/4 by cumulative property.

A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There are summations with an infinite set of parameters.

The summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.

Cumulative property is the property summation states;

x + y will be equal to y + x ⇒ x +y = y + x

Now given,

The sum of  -1 3/4 and 2 1/2 ⇒  -1 3/4 + 2 1/2  

By cumulative property,

-1 3/4 + 2 1/2   = 2 1/2 + -1 3/4

The difference between 2 1/2 and 1 3/4 ⇒  2 1/2 -  1 3/4

Hence "The sum of -1 3/4 and 2 1/2 is the same as the difference between 2 1/2 and 1 3/4 by cumulative property".

Answer:

It will take 11/30(cistern/hour) for the tank to be full

Answer:

[0, 57.5]

OR

0 - 57.5

Step-by-step explanation:

Given the function [tex]H(t)[/tex] which gives the heart rate as per time.

That means Heart rate of the runner changes according to time.

[tex]H(t)[/tex] is a function which takes Time as input as observed by the function's representation. In bracket, there is [tex]t[/tex].

That also means time [tex]t[/tex] is the input to the function [tex]H(t)[/tex].

It is also given that during the time as the runner runs, the heart beat will change.

The output of the given function will be Heart beat of the runner.

Time taken to complete the run is given as 57 minutes and 30 seconds.

Domain of a function is the valid inputs that can be given to the function for which the output of the function is defined.

Here, time in minutes is the input to the function.

So, maximum time can be 57.5 minutes.

And as the runner will start from the time = 0 minutes

So, the valid inputs can be from 0 to 57.5 minutes.

Therefore, the domain is [0, 57.5]

OR

0 - 57.5

Answer:

x = 5

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] (x + [tex]\frac{5}{2}[/tex] ) = [tex]\frac{15}{4}[/tex]

Multiply both sides by 4 to clear the fractions

2(x + [tex]\frac{5}{2}[/tex] ) = 15 ← distribute parenthesis on left side

2x + 5 = 15 ( subtract 5 from both sides )

2x = 10 ( divide both sides by 2 )

x = 5

Answer:

x = 5

Step-by-step explanation:

i solved x using trial and error

1/2 (x+ 5/2)= 15/4

so i tried with 2

1/2 (2 + 5/2)= 9/4

which is too less, so i tried with 7

1/2 (7+ 5/2)= 19/4

which is too big, so i tried with 6

1/2 (6+ 5/2)= 17/4

which is nearly there and i tried with 5

1/2 (5+ 5/2)= 15/4

and it came exactly

Answer:

(-4, -1/2)

Step-by-step explanation:

The midpoint between two points (x₁, y₁) and (x₂, y₂) is given by:

((x₁ + x₂)/2, (y₁ + y₂)/2)

So in this case:

((-3 - 5)/2, (3 - 4)/2) = (-8/2, -1/2) = (-4, -1/2)

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

2x + 3y = 10 → (1)

x + y = 7 → (2)

Multiplying (2) by - 3 and adding to (1) will eliminate y

- 3x - 3y = - 21 → (3)

Add (1) and (3) term by term to eliminate y, that is

- x = - 11 ( multiply both sides by - 1 )

x = 11

Substitute x = 11 into either of the 2 equations and evaluate for y

Substituting into (2)

11 + y = 7 ( subtract 11 from both sides )

y = - 4

Solution is (11, - 4 )

Answer:

Neptune is 2.86 times further away from Saturn.

Step-by-step explanation:

Distance from Neptune to Earth is [tex]4.3\times 10^9\ km[/tex]

Distance from Saturn to Earth is [tex]1.5\times 10^9\ km[/tex]

We need to find how many times Neptune is further away from Saturn. It can be calculated by dividing distance from Neptune to Earth to the distance from Saturn to Earth as follows :

[tex]\dfrac{d_N}{d_S}=\dfrac{4.3\times 10^9}{1.5\times 10^9}\\\\\dfrac{d_N}{d_S}=2.86\\\\d_N=2.86\times d_S[/tex]

It would mean that Neptune is 2.86 times further away from Saturn.

Answer:

Per day earning is $1.

Step-by-step explanation:

Initial balance that Usha had  = $84

Number of working days = 6 days

Total money after working 6 days = $45 × 2 = $90

Since we know that the initial amount is $84 and the final amount is $90. Thus the amount earned by working 6 days is 90 – 84 = $6.

Now we have to calculate the per day earning. Therefore, just divide the earning with number of days.

Per day earning = $6 / 6 = $1

Answer:

1/4

Step-by-step explanation:

3 red + 6 green = 9 total

P( red) = red/total = 3/9 = 1/3

Now we don't put it back

2 red + 6 green = 8 total

P( green) = green/total = 6/8 = 3/4

P (red, keep,green) = 1/3 * 3/4 = 1/4

Answer:

[tex]\Large \boxed{{\frac{1}{4} }}[/tex]

Step-by-step explanation:

There are 3 red clips and 6 green clips.

Total clips = 3 + 6 = 9

The probability of picking a red clip is 3/9 = 1/3.

You don’t put the red clip back.

Now there are 2 red clips and 6 green clips.

Total clips = 2 + 6 = 8

The probability of picking a green clip is 6/8 = 3/4

P(pulling out a red clip and then a green clip) = 1/3 × 3/4 = 3/12 = 1/4
