Answer:

Scale of Jackie's map is 1 in : 12 ft. Option B is correct.

Step-by-step explanation:

Pepper Jackie draws a map of the youth center building.

The actual length of the building = 72 feet.

The length shown in the map = 6 inches.

To calculate the scale of Jackie's Map, we divide the actual length to the length shown in the map.

72 feet = 6 inches

Therefore 1 inches = 72 ÷ 6 = 12 feet

Scale of Jackie's map is 1 in : 12 ft.

Explain how your work your knowledge of place value helps you divide a number in thousands by whole numbers to 10 give a example
Anna71 [15]
Place value is the value each digit has in its position: in order from higher to lower value, there is thousands, hundreds, tens, and ones.
When you divide by 10, you are moving (only once) every digit from its present place value to the right.
For example 6430 : 10= 643, you have moved every digit to the right, making the zero disappear (or better yet, separated by a hidden and in this case useless comma).

Each airline passenger and his or her luggage must be checked to determine whether he or she is carrying weapons on to the airpl
Dafna1 [17]

Answer:

a

P_k  = 0.83

b

 N_{\mu} \approx  4 \ passengers

c

T_{\lambda} =  0.5 \ minutes

Step-by-step explanation:

From the question we are told that

The average number of passengers that arrive per minute is \lambda = 10

The average number of check that can be carried out in one minute is \mu= 12

Generally the probability that a passenger will have to wait before being checked for weapons is mathematically represented as

        P_k  = \frac{\lambda }{ \mu }

=>    P_k  = \frac{10 }{ 12}

=>    P_k  = 0.83

Generally the number of passengers are waiting in line to enter the checkpoint is mathematically represented as

     N_{\mu} =  \frac{\lambda^2}{\mu (\mu -\lambda) }

=>  N_{\mu} =  \frac{10^2}{12 (12 -10) }

=>  N_{\mu} \approx  4 \ passengers

Generally the average time a passenger spend at the checkpoint is mathematically represented as

      T_{\lambda} = \frac{ \frac{\lambda}{(\mu - \lambda)} }{ \lambda}

=>   T_{\lambda} = \frac{ \frac{ 10}{(12 - 10)} }{10}

=>   T_{\lambda} =  0.5 \ minutes

The population of a small rural town in Iowa went from 5700 people in 1998 to 7945 in 2005. What is the rate of change in the po
Ksivusya [100]
First, the total difference of the amount of people living in the town from 1998 to 2005 is 7945-5700 or 2245 people. To find out how many years it took for this growth, we would need to subtract 1998 from 2005 to get 7 years. So, in 7 years, the town gained 2245 people. If we divide 2245 by 7 to get the unit rate, we will find that the change in population is 320.71... people per year, or if rounded, 321 people per year, which is a.

A trail runner gets a new map of her favorite mountain. • Her old map has a scale of 1 cm to 100 m. • Her new map has a scale of
KIM [24]

Answer:

The trail on her new map is 8 cm

Step-by-step explanation:

Here, we are interested in knowing the the length of the trail on the new map.

The scale on her old map is 1 cm represents 100 m

While her new map has a scale of 1 cm to 500 m

Now, running a trail of 40 cm on her old map, we need to get the actual distance.

The actual distance will be 40 * 100 = 4,000 m

Now, we shall convert this to the new map scale

We simply convert this to cm in the new map scale by dividing the 4,000 m by 500 m

That would be 4,000/500 = 8 cm

So the trail on her new map is 8 cm

The perimeter of a rectangle is 343434 units. Its width is 6.56.56, point, 5 units. Write an equation to determine the length (l
stiv31 [10]

Answer:

Step-by-step explanation:

perimiter=2(Length+Width)

P=2(L+W)

solve for L

distribute

P=2L+2W

minus 2W

P-2W=2L

divide by 2

\frac{P-2W}{2}=L

given that P=34 units and W=6.5 units

\frac{34-2(6.5)}{2}=L

the equation would be L=p2w/2 or L= p/2=w
