Step-by-step explanation:
As a small step to save the environment, Luna came up with an idea for her sweet shop. In exchange for five eclaire boxes, that she gets, she decided to give an eclaire box for free. A group of kids from the locality ate seventy-seven eclaire boxes that week and they collected the boxes to give to Luna and get back eclaires boxes.
How many eclaires boxes do you think they can buy from Luna using the seventy-seven claire boxes?
Answer: Kids will get 15 eclaire boxes in the exchange of 76 boxes.
Step-by-step explanation:
Exchange criteria:
1 Ecalaire box free for 5 eclaire boxes.
Total boxes collected by kids =76
Number of eclaire boxes they will get = 76 ÷5
= [tex]15\dfrac{1}{5}[/tex] or 15 (approx.)
i.e. they will get 15 eclaire boxes in the exchange of 76 boxes.

Answer:
1) 11 + 5x = 10 + -3x
11 + 5x = 10 + -3x
11 + 5x + 3x = 10 + -3x + 3x
5x + 3x = 8x
5x + 3x = 8x11 + 8x = 10 + -3x + 3x
-3x + 3x = 0
-3x + 3x = 011 + 8x = 10 + 0
-3x + 3x = 011 + 8x = 10 + 011 + 8x = 10
11 + -11 + 8x = 10 + -11
11 + -11 = 0
11 + -11 = 00 + 8x = 10 + -11
11 + -11 = 00 + 8x = 10 + -118x = 10 + -11
10 + -11 = -1
10 + -11 = -18x = -1

Solve : 5x+9 = 0
Solve : 5x+9 = 0 Subtract 9 from both sides of the equation :
Solve : 5x+9 = 0 Subtract 9 from both sides of the equation : 5x = -9
Solve : 5x+9 = 0 Subtract 9 from both sides of the equation : 5x = -9Divide both sides of the equation by 5:
Solve : 5x+9 = 0 Subtract 9 from both sides of the equation : 5x = -9Divide both sides of the equation by 5: x = -9/5 = -1.800
Solve : 5x+9 = 0 Subtract 9 from both sides of the equation : 5x = -9Divide both sides of the equation by 5: x = -9/5 = -1.800
Solve : 5x+9 = 0 Subtract x = -9/5 = und 5x+9 = 0
5x -9=0
x = -9/5 = -1.800
x = -9/5 = -1.800
5x+9 = 1.800
5x =-9
x = -9/5 = -1.800

Step-by-step explanation:
the circumference of a circle is 65n. In terms of pi, what is the area of the circle
Answer:
In order to answer this you would need to use this equation: A = πr² (See explanation)
Step-by-step explanation:
So, The circumference of the circle is 65n?
What you need to do is A = πr²
Let's divide 65n by Pi (65/3.14)
That equals 20.70n
Now we have the diameter of the circle. We need the radius for A = πr² .
We need to divide the diameter by two (20.70/2)
We now have the radius of the circle: 10.35n
Now we need to plug 10.35n in our Area equation :A = π10.35²
So now we multiply the Radius by Pi (π * 10.35)
This means that the area of our circle is: A = 32.49
Your answer Is 32.49n

What is the relationship between the angle of depression of a person looking down from the top of a hill at their friend standing on the ground and the angle of elevation of the person on the ground looking up at that friend who is standing on top of the hill?
A. A choice cannot be more than 600 characters - truncated. The angle of elevation will be greater than the angle of depression because the person has to look up from the ground to see their friend at the top of a hill.
B. The angle of depression and the angle of elevation will be the same

Step-by-step explanation:
Solve for the unknown in the following diagram. Round the answer to two decimal places.
degrees
Answer:
x = 63.28°
Step-by-step explanation:
A = 33°
a = 175 mm
C = x
c = 287 mm
Use the Law of Sines to find x
Thus:
[tex] \frac{a}{sin(A)} = \frac{c}{sin(C)} [/tex]
Plug in the values
[tex] \frac{175}{sin(33)} = \frac{287}{sin(x)} [/tex]
Cross multiply
[tex] 175*sin(x) = 287*sin(33) [/tex]
Divide both sides by 175
[tex] sin(x) = \frac{287*sin(33)}{175} [/tex]
[tex] sin(x) = 0.893208017 [/tex]
[tex] x = sin^{-1}(0.893208017) [/tex]
x = 63.28° (2 decimal places)
(2x2 − x) + (x2 + 3x − 1)
5x2+2x−1+(4x2−x+2)
(3x2+2x+1)+(x2−1)
−x2−1 +(4x2−x)

Many firms use on-the-job training to teach their employees computer programming. Suppose you work in the personnel department of a firm that just finished training a group of its employees to program, and you have been requested to review the performance of one of the trainees on the final test that was given to all trainees. The mean and standard deviation of the test scores are 80 and 5, respectively.
Assuming nothing is known about the distribution, what percentage of test-takers scored better than the trainee who scored 70?
a. Approximentaly 75%
b. Approximentaly all
c. At most 75%
d. At least 75%
e. None of the above
Answer:
d. At least 75%
Step-by-step explanation:
Since nothing is known about the distribution, we use the Chebyshev Theorem.
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].
In this problem, we have that:
Mean = 80, standard deviation = 5.
What percentage of test-takers scored better than the trainee who scored 70?
70 = 80 - 2*5
So 70 is two standard deviations below the mean.
Due to the Chebyshev Theorem, we know that at least 75% of the measures are within 2 standard deviations of the mean, between 70 and 90, which means that this percentage is at least 75%, and the correct answer is given by option d.
