Answer:

See explanation

Step-by-step explanation:

Consider the sequence 10, 6, 2, -2, -4, ...

Rewrite it as

a_1=10,\\ \\a_2=6,\\ \\a_3=2,\\ \\a_4=-2,\\ \\a_5=-6,...

The points on the coordinate plane are

(1,a_1),\ (2,a_2),\ (3,a_3),\ (4,a_4),\ (5,a_5),... (see attached graph).

Since

4=a_2-a_1=a_3-a_2=a_4-a_3=a_5-a_4=..., given sequence is arithmetic.

In a mixture of​ concrete, there are fourfour lb of cement mix for each pound of gravel. If the mixture contains a total of 2952
Anton [14]

Answer: there are 59059 lbs of gravel.

Step-by-step explanation:

In a mixture of​ concrete, there are four lbs of cement mix for each pound of gravel. This means that eight lbs of cement would be mixed for 2 pounds of gravel and 12 lbs of cement would be mixed for 3 pounds of gravel and 12. Therefore, the constant ratio of cement to gravel is 4:1

The total ratio is 4 + 1 = 5

If the mixture contains a total of 295295 lb of these two​ ingredients, then the number of pounds of gravel that are​ there is

1/5 × 295295 = 59059 lbs
