The average number of breaths per minute would be 67.6 breaths per minute.
Average can be calculated by dividing the sum of the observation by the number of observations,
[tex]Average = \frac{sum of observations}{number of observation}[/tex]
Step by step Explanation:
Over the course of 5 minutes, the squirrel takes
65 + 73 + 67+ 71+ 62 = 338 breaths in 5 minutes
So, the sum of observation = 338 and
the number of observations = 5
So If you take that number and divide it by the number of minutes, you will get the average.
[tex]=\frac{338}{5}[/tex]
67.6 breaths per minute.
Thus, the correct answer is - 67.6 breaths per minute.

tan6x nhân tan7x= -1
Recall that
• tan(x) = sin(x) / cos(x)
• sin(x) sin(y) = - 1/2 (cos(x + y) - cos(x - y))
• cos(x) cos(y) = 1/2 (cos(x + y) + cos(x - y))
Then we can write
tan(6x) tan(7x) = (sin(6x) sin(7x)) / (cos(6x) cos(7x))
tan(6x) tan(7x) = - (cos(13x) - cos(x)) / (cos(13x) + cos(x))
Make this replacement in the original equation and simplify:
tan(6x) tan(7x) = -1
- (cos(13x) - cos(x)) / (cos(13x) + cos(x)) = -1
(cos(13x) - cos(x)) / (cos(13x) + cos(x)) = 1
cos(13x) - cos(x) = cos(13x) + cos(x)
2 cos(x) = 0
cos(x) = 0
Solving for x gives
x = π/2 + nπ = (2n + 1)π/2
where n is any integer. However, since 2n + 1 is odd, for any odd multiple of π/2, we would end up with
tan(6 (2n + 1)π/2) = tan((2n + 1)×3π) = tan(odd multple of π/2)
since odd×odd = odd, and cos(odd multiplie of π/2) = 0, which would make tan(6x) undefined.
Therefore there are no solutions to this equation.

Can anyone please help me to find the area of this please
9514 1404 393
Answer:
√35 +3√7 -6 . . . square units
Step-by-step explanation:
The area can be figured a number of ways. The figure can be divided into parts, and the areas of those parts added.
Or, the area of the enclosing rectangle can be found, and the rectangle at upper right that is not shaded can be subtracted from that. We choose the latter.
The overall width is the sum of the given partial widths:
width = (√7 -2) + (2) = √7
Then the area of the bounding rectangle is ...
A = LW = (√5 +3)(√7) = √35 +3√7
The area of the upper right empty-space is ...
A = LW = (3)(2) = 6
Then The area of the shaded figure is ...
√35 +3√7 -6
42 = -7 ( z-3)
whats z?
Answer:
z = -3
Step-by-step explanation:
42 = -7 ( z-3)
42 = -7z + 21
21 = -7z
z = -3
Answer and Step-by-step explanation:
We have to solve for z. That means everything that is next to z has to move to the other side of the equation.
First, divide -7 from both sides of the equation.
-6 = z - 3
Now add 3 to both sides of the equation.
-3 = z
z is equal to -3.

Find the 11th term of the arithmetic sequence -5x + 6, -9x + 11, -13x + 16
Answer:
11th term is -45x+56
Answer:
a_11 = -45x + 56
Step-by-step explanation:
An arithmetic sequence has a constant difference which can be found by subtracting a term from the next term.
constant difference = d = -9x + 11 - (-5x + 6)
d = -9x + 11 + 5x - 6
d = -4x + 5
The nth term of an arithmetic sequence is
a_n = a_1 + (n - 1)d
a_11 = a_1 + (11 - 1)(-4x + 5)
a_11 = -5x + 6 + 10(-4x + 5)
a_11 = -5x + 6 - 40x + 50
a_11 = -45x + 56

At y-intercept, x is zero
substitute x as zero:
[tex]y = {(0)}^{2} + 2(0) - 8 \\ y = 0 + 0 - 8 \\ y = - 8[/tex]
Claude's net pay for the month was $985.50.
If his gross pay is $1350.00, his net pay is what percent of the gross pay?
Hello ;)
We have :
Claude's net pay → $985.50
Claude's gross pay → $1350.00
We know that the gross pay represents 100 % of the salary.
So :
$1350.00 ⇔ 100 %
$985.50 ⇔ ? %
? = 985.5 × 100 ÷ 1350 = 73 %
Claude's net pay is 73 % of the gross pay.
:-)
Based on his net pay being $985.50 and his gross pay being $1,350.00, the net pay is 73% of the gross pay.
To find out how much of the percentage of something a variable is, you make the variable the numerator and the other measure the denominator.
In this instance that would be:
= Net pay / Gross pay x 100%
= 985.50 / 1,350 x 100%
= 73%
In conclusion, the net pay is 73% of the gross pay.

Write 63 as a product of as many factors a possible. Do not use 1 as a factor.
Answer:
7 x 9 = 63 7 is a FACTOR of 63
9 is a FACTOR of 63
7 and 9 are even DIVISORS of 63
63 is a MULTIPLE of 7 and 9
63 is a PRODUCT of 7 and 9
63 is evenly DIVISIBLE by 7 or 9
Writing 63 as a product of as many factors will be: 7 × 9, 3 × 21, 9 × 7 and 21 × 3.
The factors of 63 include 1, 3, 7,9, 21 and 63.
Since we've been given the information that we should not use 1 as a factor when multiplying according to the question, then the 63 as a product of its factors will be:
3 × 21 = 63
