1) |−11| = 11, therefore Peter is at a distance of 11 feet

2) Jimmy, because each of the two points is fraction 5 over 8 unit away from 0

3) 36 + 28=64 4x4=36+4x7=28 36+28=64

7+9=16 4x16=64

If 3/7 of Z is 42, what is 5/7 of Z?

Anastasy [175]

Answer:

x = 70

Step-by-step explanation:

First to make the equation easy, divide 42 by 3 to get what 1/7 of Z equals.

42 / 3 = 14

Now to get 5/7 of Z, just multiply 14 by 5.

14 x 5 = 70

x = 70

Hope this helped.

Use sigma notation to represent the sum of a geometric series with a first term of 3 and a common ratio of . A. B. C. D.

maksim [4K]

Answer:

$\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}]$

Step-by-step explanation:

A geometric sequence is a list of numbers having a common ratio. Each term after the first is gotten by multiplying the previous one by the common ratio.

The first term is denoted by a and the common ratio is denoted by r.

A geometric sequence has the form:

a, ar, ar², ar³, . . .

The nth term of a geometric sequence is $ar^{n-1}$

Therefore the sum of the first n terms is:

$\Sigma_{k=1}^{n}(ar^{k-1})$

Given a geometric series with a first term of 3 and a common ratio of 10/9, the sum of the first n terms is:

$\Sigma_{k=1}^{n}[3(\frac{10}{9} )^{k-1}]$

Ratios- coca cola has 65g sugars total. Equivalent amount of carrots: 1.383 kg or approx 3 lbs. so question asks

dimaraw [331]

This question means that Coca-Cola, which has 65 grams of sugar in a can (I assume), has the same sugar content as 1.383 kg of carrots. Coca-Cola is a distractor in this problem. (1.383kg/65g)=(1kg/s) Can you solve from there for s?

-7x is less than or equal to -21

julsineya [31]

The answer is x=3
if you divide each by -7 to isolate x, it’s equal to positive three because 2 negatives make a positive
