Step-by-step explanation:

30 kg 500g + 28kg 700g

= 58kg + 1200g

= 59kg 200g.

Difference

= 30 kg 500g - 28kg 700g

= 2kg + 500 - 700

= 2kg - 200g

= 1kg 800g.

Answer:

3/6 of a minute

Step-by-step explanation:

3/6 can also be simplified to 1/2. So, 1/2 of a minute is 30 seconds. 2/6 can be simplified to 1/3. So, 1/3 of an hour is 20 minutes. 30 seconds is very much shorter than 20 minutes. Thus, 3/6 of a minute is shorter than 2/6 fo an hour.

Answer:

Undefined

Step-by-step explanation:

0=0

Answer:

0

Step-by-step explanation:

Combine the like terms 9x-2x = 7x

Subtract the numbers 11-5 = 6

Combine the like terms again 4x+3x = 7x

Subtract 6 from both sides of the equation 6-6 = 0 6-6 = 0

Simplify 7x = 7x

Result 0

Answer:

3,000 divided 60 are the compatible numbers, and the estimate is 50.

Step-by-step explanation:

Compatible numbers can be described as numbers which are close in value to the actual numbers and can easily be added, subtracted, multiplied, or divided mentally.

From the question, 3,000 divided 60 are the compatible numbers that provide a better estimate for the number of departments that can get the bottles because 55 can be rounded up to 60.

The estimate will therefore be as follows:

Estimate = 3,000 / 60 = 50

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Using the chain rule along with standard derivatives

Given

y = f(g(x)) , then

[tex]\frac{dy}{dx}[/tex] = f'(g(x)) × g'(x)

[tex]\frac{d}{dx}[/tex] (sinx) = cosx , [tex]\frac{d}{dx}[/tex] (cosx) = - sinx

(a)

y = sin x²

[tex]\frac{dy}{dx}[/tex] = cos x² × [tex]\frac{d}{dx}[/tex] (x² )

   = cos x² × 2x

   = 2xcosx²

(b)

y = cos4x³

[tex]\frac{dy}{dx}[/tex] = - sin4x³ × [tex]\frac{d}{dx}[/tex] (4x³ )

   = - sin4x³ × 12x²

   = - 12x²sin4x³

Answer:

y = x + 3

Step-by-step explanation:

y = mx + b

m is the slope

b is the y intercept

if m = 1 and b = 3 then

y = x + 3

Answer:

Please check the explanation.

Step-by-step explanation:

Part a)

Given

It is clear that m∠ABD and m∠CBD lie on a straight line.

Thus, the sum of m∠ABD and m∠CBD will be 180°.

Hence,

m∠ABD and m∠CBD are supplementary angles.

Part b)

As m∠ABD and m∠CBD are supplementary angles, so the sum of m∠ABD and m∠CBD will be 180°.

Thus,

m∠ABD + m∠CBD = 180°

substitute m∠ABD = (7q-46)° and m∠CBD = (3q + 6)°

(7q-46)° + (3q + 6)° =  180°

Part c)

Given the equation

(7q-46)° + (3q + 6)° =  180°

Combining the like terms

7q + 3q - 46 + 6 = 180

10q - 40 = 180

10q = 180 + 40

10q = 220

divide both sides by 10

10q/10 = 220/10

q = 22

Therefore, the value of q = 22

Part d)

As

m∠ABD = (7q-46)°

substituting q = 22

m∠ABD = 7(22) - 46

             = 154 - 46

             = 108°

also

m∠CBD = (3q + 6)°

substituting q = 22

m∠CBD = 3(22) + 6

              = 66+6

              = 72°

Therefore,

Step-by-step explanation:

Answer:

Therefore, required equation is N = 100 x [tex]2^{- \frac{t}{5730 }[/tex]

Step-by-step explanation:

According to the question it is given that

Amount of carbon atom when animal was alive is [tex]N_0[/tex] =  100g

Half life of C-14 is 5730 years

Let 'N' be the amount of carbon atom present after 't' time

since the differential equation of decay process of radioactive atom is

[tex]\frac{dN}{dt} = \lambda N[/tex] where, λ is the decay constant

on solving this we get

[tex]N = N_0 e^{-\lambda t}[/tex]

on further solving and substituting [tex]\lambda = \frac{ln2}{T_{1/2}}[/tex] we get

[tex]N = N_0 2^{- \frac{t}{T_{1/2}} }[/tex]

on substituting the value of  [tex]N_0[/tex] =  100g and [tex]T_{1/2}[/tex] = 5730 we get

N = 100 x [tex]2^{- \frac{t}{5730 }[/tex]

Step-by-step explanation:

Answer:

senior citizen cost $4

children cost $7

Step-by-step explanation:

The question is not complete

Brenda's school is selling tickets to a spring musical. On the first day of ticket sales the school sold 3 senior citizen tickets and 9 child ... The school took in $67.00 on the second day by selling 8 senior citizen tickets and 5 child tickets. What is the price each of one senior citizen ticket and one child ticket?

Given data

let senior citizens be x

and children be y

so

3x+9y= 75--------------1

on the second day

8x+5y= 67------------2

solve 1 and 2 above

3x+9y= 75     X8

8x+5y= 67      X3

 24x+72y=600

-24x+15y=201

   0x+57y= 399

divide both sides by 57

y= 399/57

y= $7

put y= 7 in eqn 1 above

3x+9*7= 75

3x+63= 75

3x=75-63

3x=12

x= 12/3

x= $4

Answer:

a) -10

b) 7

Step-by-step explanation:

a) [tex]2(x + 3) = x - 4[/tex]

[tex] = > 2x + 6 = x - 4[/tex]

[tex] = > 2x - x = - 4 - 6[/tex]

[tex] = > x = - 10[/tex]

b) [tex]4(5x - 2) = 2(9x + 3)[/tex]

[tex] = > 20x -8 = 18x + 6[/tex]

[tex] = > 20x - 18x = 8 + 6[/tex]

[tex] = > 2x = 14[/tex]

[tex] = > x = \frac{14}{2} = 7[/tex]

Answer:

a)-10 b)7

Step-by-step explanation:

a)2 ( x + 3 ) = x - 4

2x+6=x-4

2x+6-x=-4

x+6=-4

x=-4-6

x=-10

b)4 ( 5 x - 2 ) = 2 ( 9 x + 3 )

20x-8=2(9x+3)

20x-8=18x+6

20x-8-18x=6

2x-8=6

2x=6+8

2x=14

x=14/2

x=7

Answer:

No

Step-by-step explanation:

If it is a right triangle, then the Pythagorean theorem must work.

a^2 + b^2 = c^2 (a and b are the shorter sides and c is the longest)

16^2 + 20^2 = 25^2

256 + 400 = 625

656 = 625

This is not true

Answer:

  (a)  m = 10

  (b)  n = 160

Step-by-step explanation:

To rewrite the expression in the manner indicated, write an equation that sets the given expression equal to the desired expression. Then solve for the variable value. The distributive property and the usual rules of exponents apply.

The rules of exponents you can use here are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)^c = a^(bc)

  a^0 = 1

__

(a) 2^101 +2^103 = m×2^100

  2^(101-100) +2^(103-100) = m × 2^(100-100) . . . . . . . multiply by 2^(-100)

  2^1 +2^3 = m

  2 + 8 = m

  m = 10

__

(b) 2^101 +2^103 = n×4^48

  2^101 +2^103 = n×(2^2)^48 . . . . . substitute 4 = 2^2

  2^101 +2^103 = n×2^96 . . . . . . . . simplify

  2^5 +2^7 = n . . . . . . . . . . . . . . . . . as above, multiply by 2^(-96)

  32 +128 = n

  n = 160

_____

Additional comment

The rules of exponents tell you that ...

  (m × 2^100) × 2^-100 = m × 2^(100 -100) = m × 2^0 = m

This is effectively the same as dividing by 2^100. You're doing the same thing you would do to solve any linear equation: divide by the coefficient of the variable.
