An automobile uses gasoline at a rate of 35 mi/gal, which is the same as km/l (1 km = 0.6214 mi, 1 gal = 3.78 l)

Step-by-step explanation:

Given: An automobile uses gasoline at a rate of 35 mi/gal.

Now, to convert the rate from mi/ gal to km/ l , we need to multiply it by the reciprocal of 0.6214 and divide 3.78 , we get

An automobile uses gasoline at a rate of 35 mi/gal, which is the same as  .

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
