Answer:

5 3/5

Step-by-step explanation:

The wording "combined laps" means you want the sum of the two numbers of laps. You can add their integer parts and their fractional parts.

... (3 2/5) + (2 1/5) = (3 + 2) + (2/5 + 1/5)

... = 5 + 3/5 = 5 3/5

_____

The fractions add to less than 1, so no additional work is necessary.

Nataliya [291]
Use proportions.

(a)

2 workers are to 19 as x workers are to 38

2/19 = x/38

x = 4

(b)

2/19 = x/76

x = 8

(c)

2/19 = x/133

19x = 2 * 133

19x = 266

x = 14

Answer:

1st quarter := 2488.23

2nd quarter = 1646.50

3rd quarter = 1893.98

4th quarter = 1152.93

Step-by-step explanation:

Forecast demand in the next four quarters

intercept ( a ) = 3116.67 - (- 168.25 * 6.5 ) = 4210.29

Slope ( b ) = ( 219041.15 ) - ( 12 * 6.5 * 3,116.67 ) / 650 - ( 12 * ( 6.5)^2 )

                 = -24059.11 / 143 = -168.25

Forecast demand = a + bt = 4210.29 + 168.25t  

1st quarter := 2488.23

2nd quarter = 1646.50

3rd quarter = 1893.98

4th quarter = 1152.93
