Candace leaves her house and starts jogging at a pace of 480 feet per minute. Five minutes later, her brother runs after her at

a pace of 660 feet per minute. If both of them continue at these speeds, how long will it take her brother to catch up? Here is the equation that models the problem, where t represents time in hours. 480t = 660(t – 112112)

Answer:

The answer to your question is time = 20 min

Step-by-step explanation:

Data

Candace = 480 ft/min

time = 5 min

Brother = 660 ft/min

Process

1.- Calculate the distance traveled by Candace in 5 min

    distance = speed xtime

                   = 480 x 5

                   = 2400 ft

2.- Write the equations to help solve the problem

Candace    distance = 2400 + 480t

Brother      distance = 600t

3.- Solve by equality

                  2400 + 480t = 600t

                  2400 = 600t - 480t

                  2400 = 120t

                   t = 2400/120

                   t = 20 min

4.- I will solve the equation given

                   480t = 660(t - 112112)

                   480t - 660t = -112112

                            -120t = -112112

                                   t = -112112/-120

                                   t = 934 h   I think there is a mistake in the formula you

                                                      wrote.

Feliz [49]

Answer:

Step-by-step explanation:

a )

sample mean = sum total of given data / no of data

= 415.35 / 20 = 20.76

To calculate the median we arrange the data in ascending order and take the average of 10 th and 11 th term .

= 20.50 + 20.72 / 2

= 20.61

b ) To calculate the 10% trimmed mean , we neglect the largest 10% and smallest 10 % data and then calculate the mean . Here we neglect the first two smallest and last two greatest

(18.92 + 19.25 ..... + 22.43 + 22.85) / 16

= 20.74

c )

We can easily plot the data on number line from 17 to 24

d )

Maximum value of data set = 23.71 and minimum value is 18.04

mean is 20.76 , median is 20.61 and trimmed mean is 20.74

They are between maximum and minimum values of given data . Hence there is no outliers .

miss Akunina [59]

Answer:

8

Step-by-step explanation:

Since the forklift has a maximum capacity of three boxes per trip, simply divide the total number of boxes (23 boxes) by three and round up to the nearest whole unit to find the number of trips required:

n=\frac{23}{3}=7.667

Casey had to visit the dock 8 times. He moved three boxes in seven trips and two boxes in one trip.

Assuming no direct factory overhead costs (i.e., inventory carry costs) and $3 million dollars in combined promotion and sales b
alexira [117]

Answer:

Step-by-step explanation:

Given that we assume  no direct factory overhead costs (i.e., inventory carry costs) and $3 million dollars in combined promotion and sales budget, the Deal product manager wishes to achieve a product contribution margin of 35%.

Sales - variable cost = Fixed cost + profit

Here fixed cost = 3 million dollars

Sales - variable = contribution = 35%

35% should atleast meet the fixed cost

i.e. 35% = 3 million

100% = 8.57 million can be cost

Since fixed cost will not change and remain 3 million these 5,57 million can be given to material and labor costs

So material and labor cost should be limited upto 5.57 million increase.
