the arithmetic sequence ai is defined by the formula: a1 = -53 ai = ai-1 + 6 find the sum of the first 880 terms in the sequence
maxonik [38]

Answer:

The sum of the first 880 terms in the sequence is 2,273,920.

Step-by-step explanation:

Arithmetic sequence:

The difference between consecutive terms is always the same, called common difference, and the nth term is given by:

a_{n} = a_0 + (n-1)d

In which d is the common difference.

Sum of the first n terms:

The sum of the first n terms of an arithmetic sequence is given by:

S_{n} = \frac{n(a_1+a_n)}{2}

ai = ai-1 + 6

This means that d = 6

In this question:

Sum of the first 800 terms, so n = 800

First term is -53, so a_1 = -53

The 880th term is:

a_{880} = -53 + (880-1)*6 = 5221

Sum

S_{n} = \frac{880(-53+5221)}{2} = 440(-53+5221) = 2273920

The sum of the first 880 terms in the sequence is 2,273,920.

A garden hose supplies 36 gallons of water in 3 minutes. Use a table of equivalent ratios to show the garden hoses water flow in
Eduardwww [97]

Answer:

1 minute:12 gallons

1 gallon:0.0833 minutes

Step-by-step explanation:

-Let x be the number of minutes and y be the number of gallons.

-Given that 36 gallons flow in 3 minutes, our table ratios can be calculated and represented as below:

3 \ minutes=36\ gallons\\\\\therefore 1 \ minute=\frac{36}{3}=12 \ gallons\\\\2 \ minutes =12\ gallons \times 2= 24 \ gallons

#We then calculate minutes per gallon as below:

36\ gallons =3\ minutes\\\\\therefore 1 \ gallon=\frac{3}{36}\\\\=0.0833\ minutes

Hence,the flow of gallons per minute and minutes per gallon are represented in table ratios as attached.

Westkost [7]

Answer:

False, 6:4 and 18:8 are equal ratios.

Step-by-step explanation:

Given data:

6:4 ≠ 18:8

Explanation.
