Answer:

The required ratios are

At local store: Row 1) 1:24, Row 2) 1:24, Row 3)  1:24

At online store: Row 1) 1:28, Row 2) 1:25, Row 3) 1:24

Step-by-step explanation:

From the given table it is clear that

At local store:

Row 1: Cost of 1 pair of jeans = $24

Row 2: Cost of 2 pair of jeans = $48

Row 3: Cost of 3 pair of jeans = $72

At online store:

Row 1 : Cost of 1 pair of jeans = $28

Row 2: Cost of 2 pair of jeans = $50

Row 3: Cost of 3 pair of jeans = $72

We need to find the ratio of the number of pairs of jeans to the cost of the jeans.

At local store:

Row 1) 1:24

Row 2)2:48 = 1:24

Row 3) 3:72 = 1:24

At online store:

Row 1) 1:28

Row 2)2:50 = 1:25

Row 3) 3:72 = 1:24

A man drove his car at 80km per hr for 1 and a quarter hrs .He rested for 45mins and then covered 240km, at the same time. Calcu
prisoha [69]

Answer:

Probably 128 km/h, but maybe 98.5 km/h. See below.

Step-by-step explanation:

What does "at the same time" mean?

If it means that he covered the 240 km in the same time as he convered the 80 km, then this is how you solve it:

80 km in 1.25 hour

240 km in 1.25 hour

Total distance: 80 km + 240 km = 320 km

Total time: 1.25 hour + 1.25 hour = 2.5 hour

average speed = (total distance)/(total time) = 320 km / 2.5 hour = 128 km/h

If it means he covered the 240 km in the same time he covered the 80 km plus the rest, then this is how you solve it:

80 km in 1.25 hour

240 km in 1.25 hour + 45 min = 240 km in 1.25 houir + 0.75 hour = 240 km in 2 hour

Total distance: 80 km + 240 km = 320 km

Total time: 1.25 hour + 2 hour = 3.25 hour

average speed = (total distance)/(total time) = 320 km / 3.25 hour = 98.5 km/h

Hi I would like to know how I can solve this problem.
murzikaleks [220]

The n-th term is

U_n = \dfrac14 n^2 (n+1)^2

so the 39th term is

U_{39} = \dfrac14 39^2 40^2 = \boxed{608,400}

Observe that

2^3 + 4^3 + 6^3 = 2^3 + 2^3\times2^3 + 2^3\times3^3 = 8\left(1^3+2^3+3^3)

which suggests that

V_n = 8U_n = \boxed{2n^2(n+1)^2}
