Joshua, an editor for the Winston Salem Gazette, edits 1⁄6 of a page in 3 minutes. How long would it take him to edit 3 pages?
Answer:
54
Step-by-step explanation:
If we know that Josh edits at a rate of 1/6 of a page in three minutes... then using the Unit rule... we can determine that he edits 1 whole page 6 times longer than that. By doing that... we find that Josh edits 1 page in 18 minutes. From there... we multiply the time at which it takes him to edit one page (18 minutes) by 3 (pages) to get our answer.
18 x 3 = 54

In ΔXYZ, the measure of ∠Z=90°, ZY = 4, XZ = 3, and YX = 5. What ratio represents the tangent of ∠X?
Answer:
[tex]tan\ X= \frac{4}{3}[/tex]
Step-by-step explanation:
Given
[tex]Z=90\°[/tex]
[tex]ZY = 4[/tex]
[tex]XZ = 3[/tex]
[tex]YX = 5[/tex]
Required
Determine tan x
This question can be illustrated using the attached image
Tan of an angle is calculated as:
[tex]tan \theta = \frac{Opposite}{Adjacent}[/tex]
In this case, it is:
[tex]tan\ X= \frac{ZY}{XZ}[/tex]
Substitute values for ZY and XZ
[tex]tan\ X= \frac{4}{3}[/tex]
Hence, the required ratio is 4/3

What is the measure of angle x
Please Help Me Thanks
We are given the equation:
√(4x - 2) + 3 = 5
Subtracting by 3 on both sides
√(4x - 2) = 2
Squaring both sides
4x - 2 = 4
Adding 2 on both sides
4x = 6
x = 3/2
Step-by-step explanation:
Hey there!
Given;
[tex] \sqrt{4x - 2} + 3 = 5[/tex]
Shift "3" on right side.
[tex] \sqrt{4x - 2} = 5 - 3[/tex]
[tex] \sqrt{4x - 2} = 2[/tex]
Squaring on both sides.
[tex] {( \sqrt{4x - 2} )}^{2} = {2}^{2} [/tex]
Simplify it.
[tex]4x - 2 = 4[/tex]
[tex]4x = 4 + 2[/tex]
[tex]x = \frac{6}{4} [/tex]
[tex]x = \frac{3}{2} [/tex]
Therefore, X = 3/2.
Hope it helps...

Answer:
-2.7
thats the answer but i cant submit without some words lol
Answer:
n= 1.8
Step-by-step explanation:
Solve the following expression:
n/-15 = -1.2
-Multiply -1.5 on both sides:
(-1.5) n/-1.5 = -1.2(-1.5)
n=1.8
Therefore, the final answer is n = 1.8.

Find the value of StartFraction partial derivative z Over partial derivative x EndFraction at the point (1,1,1) if the equation 5 xy plus z Superscript 4 Baseline x minus 3 yz equals 3 defines z as a function of the two independent variables x and y and the partial derivative exists.
Looks like the given curve is
5xy + z⁴x - 3yz = 3
Differentiate both sides with respect to x :
5y + 4z³x ∂z/∂x + z⁴ - 3y ∂z/∂x = 0
Solve for ∂z/∂x :
(4z³x - 3y) ∂z/∂x = - (5y + z⁴)
∂z/∂x = - (5y + z⁴) / (4z³x - 3y)
At the point (1, 1, 1), this derivative is
∂z/∂x (1, 1, 1) = - (5 + 1) / (4 - 3) = -6

What could be shown about the diagonals of parallelogram PQRS to compare the proof that diagonals of a parallelogram bisect each other?
Answer:
C. PR and SQ have the same midpoing
Step-by-step explanation:
The theorems that could be shown hat the diagonals of parallelogram PQRS bisect each other are explained below.
Let the point where the diagonals intersect be called Point T.Now, looking at the parallelogram, we can say that;
∠QPT = ∠SRT (This is because the alternate angles between 2 parallel lines are always equal)
Secondly, ∠PQT= ∠RST.This is This is because the alternate angles between 2 parallel lines are always equal.
Thirdly; ∠PTQ=∠RTSThis is because they are vertically opposite angles.
Now, from AAA congruence theorem, we can say that;△PTQ is congruent to △RTS.
Thus, we can say that;
PT = RT and QT = ST
This proves that they bisect each other.

Students at a liberal arts college study for an average of 10 hours per week with a standard deviation of 2 hours per week. The distribution of their study time happens to be uni-modal, symmetric and bell shaped. Approximately 68% of students study between 8 and B hours a week. What is the value of B
Answer:
it lies between 8 hours and 12 hours in a week
Step-by-step explanation:
Since in the question it is mentioned that the distribution consist of uni-modal, symmetric and bell shaped so here the empirical formual to be used for the mean and the standard deviation
Also the 68% would be fall within one standard deviation above and below the mean
Now
1 standard deviation below the mean is
[tex]= \mu - \sigma[/tex]
= 10 - 2
= 8 hours
And, above the mean is
[tex]= \mu + \sigma[/tex]
= 10 + 2
= 12 hours
Hence, it lies between 8 hours and 12 hours in a week
