Z=82 vertical or opposite angle theorem
15x-7 + 82=180 supplementary angles theorem
so 15x +75 =180
15x=180-75
x=105/15
x=7

A company currently has 200 units of a product on hand that it orders every 2 weeks when the salesperson visits the premises. De

disa [49]

Answer: 289 units

Step-by-step explanation:

Given the following :

Inventory (I) = 180

Lead time (L) = 7 days

Review time (T) = 2 weeks = 14 days

Demand (D) = 20

Standard deviation (σ) = 5

Zscore for 95% probability = 1.645

Units to be ordered :

D(T + L) + z(σT+L)

(σT+L) = √(T + L)σ²

= √(14 + 7)5²

= √(21)25

= 22.9

D(T + L) + z(σT+L) - I

20(14 + 7) + 1.645(22.9 + 7) - I

= 420 + 49.1855 - 180

= 289.1855

= 289 quantities

The average walking speed r of a person living in a population P in thousands is modeled by the function, r(p) = 0.37 ln p + 0.0

Veseljchak [2.6K]

Answer:

The average walking speed is 1.48 feet per second

Step-by-step explanation:

we have

$r(p)=0.37ln(p)+0.05$

where

r is average walking speed

p is the population in thousands

In this problem we have

$p=48,000/1,000=48$ ----> because p in the equation is in thousands

substitute the value of p in the equation

$r(p)=0.37ln(48)+0.05$

using a calculator

$r(p)=1.48\ ft/sec$

the speed of light is 1.86×10^5 miles per second.how many miles will light travel in 4,200,000 seconds?

stiks02 [169]

Answer: $7.812*10^{11}\ miles$

Step-by-step explanation:

Let be "x" the amount of miles light will travel in 4,200,000 seconds.

Rewrite 4,200,000 seconds in Scientific notation. Move the decimal point 6 places to the left. Then:

$4,200,000\ seconds=4.2*10^6\ seconds$

According to the exercise, light travels $1.86*10^5$ miles in 1 second.

Therefore, based on this data, you can set up the following proportion:

$\frac{1.86*10^5\ miles}{1\ second}=\frac{x}{4.2*10^6\ seconds}$

And finally, you must solve for "x" in order to find its value.

(Remember the Product of powers property: $a^m*a^n=a^{mn}$ )

Then:

$(4.2*10^6\ seconds)(\frac{1.86*10^5\ miles}{1\ second})=x\\\\x=7.812*10^{11}\ miles$
