Victor had dozen boxes, with n number of water bottles in each box. After removing dozen bottles, there were 84 bottles. Find the number of bottles in each box.
Answer:
Number of bottles in each box = 8
Step-by-step explanation:
Given:
Number of boxes = 12 boxes
Number of bottle in each box = n
Number of bottle remove = 12
Number of bottle remain = 84
Find:
Number of bottles in each box.
Computation:
Total bottle = (Number of boxes)(Number of bottle in each bo)
Total bottle = 12n
12n = 12 + 84
12n = 96
n = 8
Number of bottles in each box = 8
Answer:
The number of bottles in each box is 8.
Step-by-step explanation:
Number of boxes = a dozen = 12
Number of bottles in each box = n
Total number of bottles = n x 12 = 12 n
12 bottles are removed
number of bottles
12 n - 12 = 84
12 n = 96
n = 8
So, the number of bottles in each box is 8.

A car travels 32 km due north and then 46 km in a direction 40° west of north. Find the direction of the car's resultant vector. [?] Round to the nearest hundredth.
Answer:
Step-by-step explanation:
This requires some serious work before we even begin. First off, we will convert the km to meters:
32 km = .032 m
46 km = .046 m
And then we have to deal with the angle given as 40 degrees west of north. An angle 40 degrees west of north "starts" at the north end of the compass and moves towards the west (towards the left in a counterclockwise manner) 40 degrees. That means that the angle that is made with the negative x axis is a 50 degree angle. BUT the way angles are measured in standard form are from the positive x-axis, therefore:
40 degrees west of north = 50 degrees with the negative x axis = 130 degrees with the positive x axis. 130 is the angle measure we use. Phew! Now we're ready to start. Adding vectors requires us to use the x and y components of vectors in order to add them.
[tex]A_x=.032cos90.0[/tex] so
[tex]A_x=0[/tex] (the 90 degrees comes from "due north")
[tex]B_x=.046cos130[/tex] so
[tex]B_x=-.030[/tex] and if we add those to get the x component of the resultant vector, C:
[tex]C_x=-.030[/tex] And onto the y components:
[tex]A_y=.032sin90.0[/tex] so
[tex]A_y=.032[/tex]
[tex]B_y=.046sin130[/tex] so
[tex]B_y=.035[/tex] and if we add those together to get the y component of the resultant vector, C:
[tex]C_y=.067[/tex] Note that since [tex]C_x[/tex] is negative and [tex]C_y[/tex] is positive, the resultant angle (the direction) will put us into QII.
We find the magnitude of C:
[tex]C_{mag}=\sqrt{(-.030)^2+(.067)^2}[/tex]
We will round this after we take the square root to the thousandths place.
[tex]C_{mag}=.073m[/tex] and now for the angle:
[tex]\theta=tan^{-1}(\frac{.067}{-.030})[/tex] which gives us an angle measure of -67, but since we are in QII, we add 180 to that to get that, in sum:
The magnitude of the resultant vector is .073 m at 113°

in parallelogram ABCD the measure of m
A) 82.5
B) 97.5
C) 120
D) 130
The measure of the angle C is 120°.
Given that the parallelogram ABCD, we need to find the measure of the angle C,
We know that in a parallelogram the opposite angles are equal and the adjacent angles are supplementary,
So,
∠D = ∠B
6x + 6 = 10x - 30
4x = 36
x = 9
So, ∠D = ∠B = 60°
So,
∠C + ∠D = 180°
∠C = 180° - 60°
∠C = 120°
Hence the measure of the angle C is 120°.

If 65% of a number is 1105 what is 82% of the number
Answer:
1394
Step-by-step explanation:
Set up equation to find the number:
Variable n = number
65/100 = 1105/n
Cross multiply:
65 × n = 100 × 1105
65n = 110,500
n = 1700
Check your work:
1700 × 65%
Convert percentage into decimal:
1700 × 0.65
1105
Correct!
Find 82% of 1700:
Variable x = 82% of 1700
82/100 = x/1700
82 × 1700 = 100 × x
139,400 = 100x
1394 = x
Check your work:
1700 × 82%
1700 × 0.82
1394
Correct!
The 82% of the original number (1700) is approximately 1394.
Let's denote the original number as N. We know that 65% of N is equal to 1105. We can write this as:
65% of N = 0.65 * N = 1105
Now, to find the value of N, we can rearrange the equation to solve for N:
N = 1105 / 0.65
Now, calculate the value of N:
N ≈ 1700
So, the original number N is approximately 1700.
Next, we need to find 82% of this number. We can express this as:
82% of N = 0.82 * N
Now, substitute the value of N:
82% of 1700 = 0.82 * 1700
≈ 1394
Thus, 82% of the original number (1700) is approximately 1394.
To summarize, first, we found the value of the original number (N) using the given information that 65% of N is equal to 1105. Then, we calculated 82% of N, which turned out to be approximately 1394.

Kevin says that lines p and m will eventually intersect. Lines A and B intersect. Plane A contains lines p, m, and n. Line n is horizontal on the plane. Lines p and m are both going in the same direction and are identical. Plane B contains vertical line l which forms a right angle with line n. Is Kevin correct?
Answer:
No, because they are parallel.
Step-by-step explanation:
The lines [tex]p[/tex] and [tex]m[/tex] will not intersect, so Kevin is not correct.
It is given that planes A and B intersects. The plane A contains the line p, m and n on its plane. The lines p and m are parallel to each other. They are identical and move in the same direction.
Since the line p and m are parallel, they will not meet each other at any point because parallel lines does not intersect or meet at a point, they run parallelly along each other.
So, line p and m will not intersect.
Thus the answer is " No, because they are parallel."

Decide whether the graphs of the given euqations are parallel perpendicular or neither
Explanation:
Each equation given to you is in y = mx+b form (aka slope intercept form).
The slope m is what we'll focus on.
The first equation has slope of 1, while the second equation has slope -1.
The two slopes multiply to -1. This is a property of any pair of perpendicular lines, as long as neither line is vertical nor horizontal.
Or you could note that -1 is the negative reciprocal of 1, or vice versa.
So there are a few options to see why the lines are perpendicular.
