He buys one bag of dog food every 4 weeks so on dog food he spends 67.59 each week
7×1.29=9.03 in one week he spends 9.03 on canned food, so in four weeks he spends 36.12 on canned food
to find how much he spends in 4 weeks add the value of the dog food and the value of the canned food together
36.12+67.59=103.71

In four weeks Bruce spends $103.71

The sum of the squares of two consecutive positive integers is 41. Find the two
Komok [63]

We have to present the number 41 as the sum of two squares of consecutive positive integers.

1² = 1

2² = 4

3² = 9

4² = 16

5² = 25

16 + 25 = 41

<h3>Answer: 4 and 5</h3>

Other method:

n, n + 1 - two consecutive positive integers

The equation:

n² + (n + 1)² = 41     <em>use (a + b)² = a² + 2ab + b²</em>

n² + n² + 2(n)(1) + 1² = 41

2n² + 2n + 1 = 41     <em>subtract 41 from both sides</em>

2n² + 2n - 40 = 0     <em>divide both sides by 2</em>

n² + n - 20 = 0

n² + 5n - 4n - 20= 0

n(n + 5) - 4(n + 5) = 0

(n + 5)(n - 4) = 0 ↔ n + 5 = 0 ∨ n - 4 =0

n = -5 < 0 ∨ n = 4 >0

n = 4

n + 1 = 4 + 1 = 5

<h3>Answer: 4 and 5.</h3>

A matrix a is given. determine if the system ax = b (where x and b have the appropriate number of components) has a solution for
Alborosie
We can write the system in the following form:
\left[\begin{array}{cccc}5&-4&4&2\end{array}\right]  \left[\begin{array}{c}x_1\\x_2\\x_3\\x_4\end{array}\right]  =b
The above system is equivalent to the following equation:
5x_1-4x_2+4x_3+2x_4=b,\forall b\in\mathbb{R}
Of course, the above system has solution for any values of b since there is one equation and four variable, there is infinite number of solution each time.

A radio talk show host asks listeners to call the radio station and give their opinions on a proposed new city ordinance. He use
vladimir1956 [14]
I would say that the best answer is actually that people who are not opposed to the new rule are less motivated to call than the people who are opposing it, who feel that they need to do something about it.

But this is not one of the options. Among the options, the best is:
A.  The survey is voluntary and includes only listeners of this radio program.
