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

Which one do you need help with

Answer:

The expression : 12x + 2.50y

Total cost = $103.5

Step-by-step explanation:

The number of people that went to the movie = x

Number of people that bought drinks = y

Total cost = 12x + 2.50y

Eight people went to a movie and three of them purchased a drink

Total cost = 12 × 8 + 2.50 × 3

Total cost = 96 + 7.5

Total cost = $103.5

Answer:

12+12+14+15+16+18+20+23=130

130÷8=16.25

Answer:

A) 5/8

Step-by-step explanation:

5 and 8 are irrational as a fraction

Answer:

5/8 i TOOK THE EXAM REVIEW

Step-by-step explanation:

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

180.5%/100 = 1.805

1.805 * 99 = 178.695

Answer:

Below.

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:

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:

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]

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

the answer is 2 years because if right now florida has 9 million dogs and each year 3 million are gained in 2 years there will be 15 million dogs. if there are 13 million cats in Florida right now and 1 million and gained every year. in 2 years there will be 15 million cats.

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.

Step-by-step explanation:

P(8)

There are 4 eights in a standard deck (no jokers) So the probability is 4/52 = 1/13 = 0.0769

P( ~ 8)

48 cards in a standard deck are not 8

P( ~8) = 12/13  = 0.9231

Answer:

  x = 1

Step-by-step explanation:

The slope formula can be useful here.

  m = (y2 -y1)/(x2 -x1)

  -1 = (8 -2)/(-5 -x)

  5 + x = 6 . . . . . . . . multiply by (-5-x)

  x = 1 . . . . . . . . subtract 5

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

Step-by-step explanation:

5×10³) × (9×10^7)

= 45 × 10^10

= 4.5 × 10¹¹

Answer:

(5*10^3)*(9*10^7)=4.5*10^11

Step-by-step explanation:

5*10^3=5*1000=5000

9*10^7=9*10000000=90000000

5000*90000000=5*1000*9*10000000=5*9*10000000000=45*10000000000=450000000000, or 45 with 10 0's, or 10^10

45*10^10 is not simplified, as we need a number less then 10, so we divide 10 from 45, and add 1 to the exponent, getting 4.5*10^11

Answer:

Depends on what you what to do in the future. But u should take math, science and english (those are the main important classes)

Step-by-step explanation:

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:

29.25

Step-by-step explanation:

15x1.95= 29.25

Hope this helps :)

if 1 article = 1.95

then if u want to find how much 15 articles = to

you just have to multiply 1.95 * 15 which is equal to 29.25

hope this helps
