Step-by-step explanation:

The number that would not belong is [tex]\sqrt{48}[/tex] since it is irrational

Answer:

[tex]\sqrt{48}[/tex]

Step-by-step explanation:

Looking at the numbers, we can see that the first number, third, and fourth number are all rational numbers since they either repeat or terminate.

On the other hand, let's try and simplify the square root of 48:

[tex]\sqrt{48}=\sqrt{16\cdot3}=\sqrt{16}\cdot\sqrt3=4\sqrt3[/tex]

The square root of 3 is irrational. Therefore, 4 times the square root of 3 is also irrational. All of the given numbers are rational instead of the second one. So, the second number does not belong .

Answer:

[tex]14y^{2} -64y[/tex]

Step-by-step explanation:

Hello!

4y(5y - 11)

Distribute the 4y

4y * 5y = 20y^2

4y * -11 = -44y

Put it together

20y^2 - 44y

2y(3y + 10)

Distribute the -2y

-2y * 3y = -6y^2

-2y * 10 = -20y

Put it gether

-6y^2 - 20y

Put it all together

20y^2 - 44y - 6y^2 - 20y

Combine like terms

14y^2 - 64y

The answer is [tex]14y^{2} -64y[/tex]

Hope this helps!

Answer:

D

Step-by-step explanation:

We would like to solve:

(3/4h + 4) - (1/2h + 1)

This is equivalent to:

3/4h + 4 - 1/2h - 1

First, combine like terms; that is, combine the terms with h in them and combine the terms without h in them:

3/4h - 1/2h + 4 - 1

The common denominator for 3/4 and 1/2 is 4, so:

3/4h - 1/2h = 3/4h - 2/4h = 1/4h

Put this back in:

1/4h + 4 - 1

1/4h + 3

The answer is thus D.

9.) (-6)^2

10.) 10^3

11.) (2/3)^6

Answer:

see below

Step-by-step explanation:

( -6) * (-6)

The base is -6.  It is multiplied 2 times so the exponent is 2

(-6)^2

10*10*10

The base is 10 It is multiplied 3 times so the exponent is 3

10 ^3

2/3 * 2/3 * 2/3 * 2/3 *2/3 *2/3

The base is 2/3.  It is multiplied 6 times so the exponent is 6

(2/3) ^6

Hello There!!~

The units of per hours is = 4.5

Explanation:

Unit rate in miles per hour is the ratio of total distance covered in miles to total time taken in hour to cover that distance.

L = 3/4

Time taken to cover the loop on monday:-

T = 1/6 hours.

Unit rate in miles per hour :-

V = L/T

=> 3/4 ,1/6 =18/4

18/4 = 4 5

Answer:

28 = x

Step-by-step explanation:

62 =  angle BAC  since they are vertical angles

angle ABC is a right angle since KL is perpendicular to FG

Adding the angles in triangle ABC

BAC + ABC + BCA = 180

62 + 90 + BCA = 180

152 + BCA = 180

BCA = 180-152

BCA = 28

BCA = x since they are vertical angles

28 = x

Answer:

You will only be able to buy two at the original price the following day.

Step-by-step explanation:

You spend $30.40 on 4 CDs. Each CD costs the same amount and is on sale for 80% of the original price.

If x = original cost of one CD

80% of one CD = 0.8x

0.8x = the price you pay for one discounted CD

You buy 4 of the discounted CDs for $30.40

4(0.8x) = 30.40

solve for x, the original cost of one CD

3.2x = 30.40

x = 9.50

The next day, the CDs are no longer one sale. You have $25. Will you be able to buy 3 more CDs?

25$ / $9.50 = 2.63 CDs

Answer:

New radius(r) = 3.65 (Approx)

Step-by-step explanation:

Given:

Radius of sphere(R) = 8

Find:

New radius(r)

Computation:

Volume of sphere = (4/3)πR³

Volume of sphere = (4/3)π(6)³

Volume of sphere = 288π

Volume of ring = (4/3)π(R²-r²)³/²

Half volume of sphere = Volume of ring

288π / 2 = (4/3)π(R²-r²)³/²

144 = (4/3)(6²-r²)³/²

108 = (6²-r²)³/²

New radius(r) = 3.65 (Approx)

Answer:

512.4274 miles

Step-by-step explanation:

500m + 20k = distance

1 kilometer = 0.621371 miles

20k = 12.4274

500 + 12.4274 = 512.4274 miles

Answer:

i. Term = [tex]\frac{b_{1}h }{2}[/tex] + [tex]\frac{b_{2}h }{2}[/tex]

ii. Coefficient = [tex]\frac{1}{2}[/tex]

iii. Constant = [tex]\frac{1}{2}[/tex]

iv. Factor = [tex]\frac{h}{2}[/tex]

Step-by-step explanation:

A trapezoid is a quadrilateral which has its base parallel to the opposite side. It's area can be determined by;

Area of trapezium = [tex]\frac{1}{2}[/tex] ([tex]b_{1}[/tex] + [tex]b_{2}[/tex])h

Where [tex]b_{1}[/tex] is the measure of length of its fist base,  [tex]b_{2}[/tex] is the measure of its second base and h is its height.

Considering the given question,

Term = [tex]\frac{b_{1}h }{2}[/tex] + [tex]\frac{b_{2}h }{2}[/tex]

Coefficient = [tex]\frac{1}{2}[/tex]

Constant = [tex]\frac{1}{2}[/tex]

Factor = [tex]\frac{h}{2}[/tex]

Answer:

Rs. 112000

Step-by-step explanation:

Hari is due to pay after 3 years:

He pays Rs. 70700, remaining money is cleared by giving buffalo.

Cost of buffalo:

Answer is: Rs. 112000

Answer:

Solution,

principal(P)= Rs. 126000

Rate(R)=15%

Time(T)=3 years

Money paid=Rs.70700

Cost of buffalo=?

We know that,

                          Interest=P*T*R

                                           100

                                       = Rs. 126000*3*15

                                                         100

                                       = Rs. 56700

Now,

         Amount(A)=P+I

                           =Rs. ( 56700+126000)

                           = Rs.182700

Again,

          by the question,

                                    Cost of buffalo= Amount- Money paid

                                                             = Rs.(182700- 70700)

                                                              = Rs. 112000

Therefore, the cost of buffalo is Rs. 112000.

Total lost yards = 10 yards  

Step-by-step explanation:

Given:

First match = lost 3 yards

Second match = lost 5 yards

Third match = lost 2 yards

Find:

Total lost yards

Computation:

Total lost yards = First match + Second match + Third match

Total lost yards = 3 yards + 5 yards + 2 yards

Total lost yards = 10 yards  

Answer:

x + 2y = 20

Step-by-step explanation:

We require the slope and the midpoint of AB

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = A(2, 4) and (x₂, y₂ ) = B(6, 12)

m = [tex]\frac{12-4}{6-2}[/tex] = [tex]\frac{8}{4}[/tex] = 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]

-----------------------------------

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] ]

Thus midpoint of AB = ( [tex]\frac{2+6}{2}[/tex], [tex]\frac{4+12}{2}[/tex] ) = (4, 8 )

--------------------------------------------

y = - [tex]\frac{1}{2}[/tex] x + c ← partial equation of perpendicular bisector

To find c substitute (4, 8) into the partial equation

8 = - 2 + c ⇒ c = 8 + 2 = 10

y = - [tex]\frac{1}{2}[/tex] x + 10 ← in slope- intercept form

Multiply through by 2

2y = - x + 20 ( add x to both sides )

x + 2y = 20 ← in the form ax + by = c

See explanation below

Step-by-step explanation:

(a) The spread of the data is represented by their range,

Adam's Range : 106 - 91 = 15

Miguel's Range : 105 - 86 = 19

As Miguel's Range is greater, his data has the greater spread

(b) The middle 50 percent of both data sets would be the following,

Adam | 103 | 105 | 104 | 106 | 100

Miguel | 88 | 86 | 89 | 93 | 105

And their 50% range would be ...

Adam's 50% Range : 106 - 100 = 6,

Miguel's 50% Range : 105 - 86 = 19

Adam still has the least spread, even in the middle 50%

(c) This proves that their is a small variance in Adam's training times, but a large variance in Miguel's training times (Miguel's data is more likely skewed).
