Answer:

1575 kg

Step-by-step explanation:

Decay rate formula =

N(t) = No(1/2)^t/t½

No = Initial amount = 12600kg

N(t) = Amount after time t

t½ = half life = 8 days

t = time = 24 days

N(24) = 12600 × (1/2)^24/8

1575kg

Answer:

Step-by-step explanation:

let the number of children be x

and the number of adults be y

so

12x+3y=162-----1

and

8x+3y=122------2

equating both 1 and 2 we have

12x+3y=162-----1

8x+3y=122------2

subtract 2 from 1 we have

  12x+3y=162-----1

 - 8x+3y=122------2

    4y+0=40

4y=40

y=40/4

y=10

put y=4 in eqn 1 we have

12x+3y=162-----1

12x+3*10=162-----1

12x+30=162

12x=162-30

12x=132

x=132/12  

x=11

therefore a child will cost $11 and adult will cost $10

A survey found that​ women's heights are normally distributed with mean 64.2 in. and standard deviation 4.2 in. The survey also found that​ men's heights are normally distributed with mean 70.1 in. and standard deviation 4.1 in. Most of the live characters employed at an amusement park have height requirements of a minimum of 57 in. and a maximum of 63 in. Complete parts​ (a) and​ (b) below

a) find the percentage of women meeting the height requirement

b) find the percentage of men meeting the height requirement

Answer:

a

P(57 <  X <  63) = 34.4%

b

P(57 <  X <  63) =  4.096%

Step-by-step explanation:

From the question we are told that

    The mean of women's height is [tex]\mu_ 1 = 64.2[/tex]

    The standard deviation is [tex]\sigma_1 = 4.2 \ in[/tex]

     The mean of men' height is [tex]\mu_2 = 70.1 \ in[/tex]

     The standard deviation of men's height is [tex]\sigma_2 = 4.1 \ in[/tex]

      The minimum height requirement is  a =  57 in

      The maximum height requirement is  b = 63 in

Generally the percentage of women meeting the height requirement  is mathematically represented as

     [tex]P(57 < X < 63) = P(\frac{ 57 - 64.2}{ 4.2} < \frac{X - \mu_1}{\sigma_1} < \frac{ 63 - 64.2}{ 4.2} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

So

      [tex]P(57 < X < 63) = P( -1.7143 < Z <-0.2857)[/tex]

=>  [tex]P(57 < X < 63) = P ( Z <-0.2857) - P(Z < -1.7143)[/tex]

Generally from the z table the probability of  ( Z <-0.2857)  and  (Z <  -1.7143) is  

    P( Z <-0.2857)   =  0.38755

 and

    P(Z <  -1.7143) =  0.043237

So

   P(57 <  X <  63) = 0.38755  - 0.043237

=>  P(57 <  X <  63) = 0.3443

Converting to percentage

     P(57 <  X <  63) = 0.3443  * 100 =  34.4%

Generally the percentage of men meeting the height requirement  is mathematically represented as

     [tex]P(57 < X < 63) = P(\frac{ 57 - 70.1}{ 4.1} < \frac{X - \mu_1}{\sigma_1} < \frac{ 63 - 70.1}{ 4.1} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

So

      P(57 <  X <  63) = P( -3.1951  < Z <-1.7317)

=>  [tex]P(57 < X < 63) = P ( Z <-1.7317) - P(Z < -3.1951)[/tex]

Generally from the z table the probability of  ( Z <-0.2857)  and  (Z <  -1.7143) is  

    P( Z <-1.7317)   =  0.041663

 and

    P(Z <  -3.1951 ) =  0.00069891

So

   P(57 <  X <  63) = 0.041663  - 0.00069891

=>  P(57 <  X <  63) = 0.04096

Converting to percentage

     P(57 <  X <  63) = 0.04096   * 100 =  4.096%

Answer:

28 feet

Step-by-step explanation:

A monkey sits on a limb that is 25 feet above the ground

He swings up 10 feet

Climbs up 6 feet

He then jumps down 13 feet

Therefore the distance of the monkey from the ground can be calculated as follows

= 25 + 10 +6 - 13

= 41-13

= 28 feet

Answer:

Question 2: D. 604.9

Question 3: 80 oranges or 10/30 or 1/3

Step-by-step explanation:

For question 2:

Okay so, Hal has 5 3/4 bags of munch and each bag covers 105.2 area. We can take the whole number that is already there (5) and multiply it by 105.2 since it is the amount of 1 full bag. So: 5(105.2) is equal to 526.

Now we have to figure out how much 3/4 of a bag is. So take the amount of the full bag and divide it by the denominator (4). So: 105.2/4 is equal to 26.3. Now we know that for 1/4 of a bag it can cover 26.3. We are trying to find the 3/4 so take 1/4 and multiply it by 3 to get 3/4. We can do the same to the amount it is equal with: 26.3(3) and you get 78.9 as an amount of 3/4 of a bag of munch.

Now we add the 3/4 and 5 whole bags: 526.0+78.9=604.9

Our final answer is 604.9 so, option D is correct.

For question 3:

Basically taking all the given fractions: 1/5, 1/6 and 3/10. The lowest amount I can think of is multiplying the denominators to get 30 since they can all equal to 30. So multiply the denominator and numerator for each fraction:

1/5x6=6/30

1/6x5=5/30

3/10x3=9/30

Notice that the denominators are all equal to 30 so this allows us to now add them together.

6/30 + 5/30 + 9/30 = 20/30

Now we know that all together 20/30 is the already know fruits we can easily assume the 10/30 is the amount of oranges. We need to figure out the whole number and not the fraction so, take 240 and divide it by the denominator (30) and we get how much 1/30 is worth in a whole number. So: 240/30=8.

Now we know that 1/30=8 pieces of fruit. Take the 20/30 for already known fruit and we get 160. Take the 10/30 for oranges and we get: 10/30(8) is equal to 80 oranges.

So:

80 oranges

160 other known fruits

Basically 160=2/3 and 80=1/3.

We can check if this is true by:

2/3 (known fruit) and multiply the denominator and numerator by 10 to get 30:

2/3(10)= 20/30. We know this correct because 20/30 is the same as the known fruits fraction we got earlier. Next 1/3(10)=10/30 the 10/30 that was also equal to the amount of oranges.

Our final answer is 80 oranges or 10/30 or 1/3

I hope this helps:)

Answer:

The zero value of the function occurs at s = 4

Step-by-step explanation:

The given function for the amount of money, m, Jason has left after buying s number of sno-cones for his friend is m = 5 - 1.25·s

Therefore, we have generated from Microsoft Excel the following data table used to plot the points on the graph

Number of Sno-cones          [tex]{}[/tex]        Amount of money left

0                                    [tex]{}[/tex]                        5

1                                    [tex]{}[/tex]                         3.75

2                                    [tex]{}[/tex]                        2.5

3                                    [tex]{}[/tex]                        1.25

4                                    [tex]{}[/tex]                        0

Therefore, as seen from the above table, and from the attached graph, the zero value of the function occurs at the value where the amount of money left (y-coordinate value) is 0 which is at the value of s = 4.

Answer:

Option (B)

Step-by-step explanation:

Let the amount of apricots purchased = a pounds

and the amount of bananas purchased = b pounds

Since, Andre purchased total amount of apricots and bananas = 5 pounds

Equation for the total amount will be,

a + b = 5

If the cost of bananas = $4 per pounds and the cost of apricots = $6 per pound

Total amount spent = $24.50

Therefore, equation for the expense will be,

6a + 4b = 24.50

Therefore, Option (B) will be the answer.

Step-by-step explanation:

-525 and (35)(-15)

Step-by-step explanation:

You can calculate the result of this expression as follows:

(-7)(-15)(-5)=(-1)³(7×15×5)=-(7×15×5)=-525

as, (-1)^n=1 if n is even and (-1)^n=-1 if n is odd.

We already saw that -525 is equivalent to the expression. Furthermore:

(-7)(-15)(-5)=(-15)(-7)(-5)=(-15)(-1)²(7×5)=(-15)(7×5)=(-15)(35).

so the second expression is also equivalent.

You can discard the third and fourth answers because 115×5=575≠525. The first one is also discarded, because (-7)(75)=525≠-525.

The value of equivalent expression are, (- 1)(525) and (35)(- 15).

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, We can check all the options as,

(- 7) (-15) (- 5)

= (105)(-5)

= - 525

(–7)(–75) and (–1)(525)

= 525   &  - 525  

Not Equal

(–1)(525) and (35)(–15)

= -525  and - 525

Both Equal to  (- 7) (-15) (- 5)

(35)(–15) and (115)(–5)

= -525  and   - 575

Not Equal

(–1)(525) and (115)(–5)

= -525  and - 575

Not Equal

Hence, Expressions (- 1)(525) and (35)(- 15) are equivalent to (- 7) (-15) (- 5).

Answer:Therefore Natalie bought   3 water melons  and  10 strawberries

Step-by-step explanation:

Step 1

let watermelons be represented by w

and strawberries be represented by s

Step 2

5w +3s = $45.......eqn 1

w+s=13..........eqn 2

Making w subject of formulae and substituting in equation 2

w= 13-s

5(13-s) + 3s=45

65-5s+3s =45

65-45=5s-3s

20=2s

s=20/2=10

substituting s=10  in equation 2

w +10=13

w= 13-10

w=3

Therefore Natalie bought   3 water melons  and  10 strawberries

Answer:

59%

Step-by-step explanation:

it says there is 200 animal and 82 are cats. we're trying to find the number of dogs. So subtract 82 from 200. that equals 118/200. 118/200 is 59%

If there are 200 animals at the rescue center, the percentage of animals that are dogs is 59%.

Given the following data:

To find the percentage of animals that are dogs:

[tex]Total \;animals = C + D[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]200 = 82 + D\\\\D = 200 - 82[/tex]

Dogs, D = 118 dogs.

Now, we can find the percentage of animals that are dogs:

[tex]Percent = \frac{D}{T}\times 100\\\\Percent = \frac{118}{200}\times 100\\\\Percent = 0.59 \times 100[/tex]

Percent of dogs = 59%
