Answer:

Since the question requires you to give the answer in terms of steps/minute, the first step would be to convert hours to minutes:

12.5 hours = 750 minutes

Next, if he took 775 steps in 750 minutes, how many would he take in 1 minute?

This requires you to set up the question as a proportion:

(775 steps/ 750 minutes) = (x steps/1 minute)

(1 * 775)/750 = 31/30 = 1.033

he took ~1 step per minute

Mackenzie has a loyalty card good for a 20% discount at her local hardware store. What would her total in dollars and cents be,

8_murik_8 [283]

Answer: $14.0

Step-by-step explanation:

For us to calculate this question, we have to find 20% of $17.45 and then subtract the value gotten from $17.45. This will be:

= $17.45 - (20% × $17.45)

= $17.45 - (0.2 × $17.45)

= $17.45 - $3.49

= $13.96

= $14.0 to nearest cent

Answer:

$0.5a+7.5b^2$

Step-by-step explanation:

$4b^2+3.5a-2a+3.5b^2-a$

Group similar terms together:

$3.5a-2a-a+4b^2+3.5b^2$

Add the term $b^2$ :

$3.5a-2a-a+7.5b^2$

Subtract the term a:

$0.5a+7.5b^2$

miskamm [114]

10% of $560 is $56

So 5% is $28

1% of $560 is $5.60

So now half $5.60 is $2.80

$2.80 is 0.05%

Now add

$28 + $2.80 = $30.80

Total is $30.80

Weekly demand for a particular item averages 30 units, with a standard deviation of 4. This item is managed with a fixed-order-i

aivan3 [116]

Answer:

(B)93

Explanation:

Since we are using a fixed-order-interval model,

The Amount to Order=Expected Demand During protection Interval+Safety Stock-Amount at Hand

$=d(OI+LT)+z\sigma_{d}\sqrt{OI+LT}-A$

Where:

d=weekly demand

OI=Order Interval

LT=Lead Time

z=Standard Deviation of Desired Service Level

$\sigma_{d}$ =Standard Deviation of weekly Demand

A= Amount at Hand

$=d(OI+LT)+z\sigma_{d}\sqrt{OI+LT}-A$

$[30(3 + 1)] + [1.964*4*\sqrt{3 + 1} - 43$

$= 120 + 15.712 - 43 = 92.7$
