6(15) + 10b > = 200
90 + 10b > = 200
10b > = 200 - 90
10b > = 110
b > = 110/10
b > = 11

so she can do 15 days of running plus 11 days of biking....which totals 26 days

Louis found two bakeries to provide bagels for his sub shop. The first bakery offers 350 bagels for $168.00 and the second baker
borishaifa [10]

Answer:

<h2>$352</h2>

Step-by-step explanation:

Find out the price of one bagel by dividing the price by the number of bagels:

350 Bagels = $168

1 Bagel = $0.48

475 Bagels = $209

1 Bagel = $0.44

0.48 > 0.44

This means the second bakery has the lower price.

Louis wants 800 bagels, so multiply the price by 800.

0.44 * 800 = $352

You can check it's lower by comparing it with the first bakery.

0.48 * 800 = $384

384 > 352

Lieutenant Commander Data is planning to make his monthly (every 30 days) trek to Gamma Hydra City to pick up a supply of isolin
Nookie1986 [14]

Answer:

a

 N  =  209 \ unites

b

 N_{max}  =  249  

Step-by-step explanation:

From the question we are told that

   The daily demand is  d =  7/day

   The  standard deviation is  \sigma  =  3 /day

   The  service probability is  s =  95\%  =  0.95

    The number of chips  in the inventory is k  =  40

   The number of days in his monthly is  T =  30 \  days

    The lead time is  L  =  4

 

Generally the number he should order (optimal order ) is mathematically represented as

      N  =  d(L  +  T)+(\sigma_{T + L}  * z)  -k

Here \sigma__{T+L }} is the monthly standard deviation which is mathematically evaluated as

            \sigma__{T  + L}} =  \sqrt{(T + L) * 1^2}

=>         \sigma__{T  + L}}  =  \sqrt{34}

=>          \sigma__{T+L}} =  5.83

Also  z-value  for the  95% service probability  from the z-table  is  1.96

So

      N  =  7 *  (30 +4 ) + (1.96 *  5.83) - 40

=>     N  =  209 \ unites

For the maximum order quantity  k =  0

So

    N_{max} = d(L  +  T)+(\sigma_{T + L}  * z)  -0

=> N_{max}  =  7 *  (30 +4 ) + (1.96 *  5.83) - 0

=>  N_{max}  =  249

What are the solution(s) to the quadratic equation 50 - x2 = 0?
Pie

Answer:

±5sqrt(2) = x

Step-by-step explanation:

50 - x^2 = 0

Add x^2 to each side

50 - x^2 +x^2= 0+x^2

50 = x^2

Take the square root of each side

±sqrt(50) = sqrt(x^2)

±sqrt(25*2)) = x

±sqrt(25) sqrt(2) = x

±5sqrt(2) = x
