An equation that uses a unit fraction and a whole number to write a multiplication equation equal to 712 can be represented as:
712 = (1/N) * X
Where N is the unit fraction and X is the whole number. To find the values of N and X, we can isolate X on one side of the equation and divide both sides by (1/N):
X = (712 * N) / (1)
X = 712 * N
Now we can substitute the value 712 for the right side of the equation:
X = 712 * N
X = 712 / (1/N)
Finally, we can simplify the equation by dividing 712 by the reciprocal of N:
X = 712 * N
X = 712 / (1/N)
X = 712 * N / (1/N)
X = 712 * N * N
Now we have an equation in which X is equal to 712 times N times N. To find the values of N and X, we can use trial and error or other mathematical methods.
It is important to note that there may be multiple solutions to this equation, as there can be many unit fractions and whole numbers that multiply to equal 712. The goal is to find a combination of N and X that satisfies the equation and produces the desired result.
In conclusion, writing a multiplication equation equal to 712 using a unit fraction and a whole number is a common mathematical problem that can be solved by isolating the variable and dividing both sides by the unit fraction.

In the diagram below, RA is parallel to ET, and RT is 21 units long. Find the length of ST.
Answer:
ST = 12 units
Step-by-step explanation:
Δ STE and Δ SRA are similar ( AA postulate ) , then the ratios of corresponding sides are in proportion, that is
[tex]\frac{ST}{SR}[/tex] = [tex]\frac{TE}{RA}[/tex] ( substitute values )
[tex]\frac{ST}{21-ST}[/tex] = [tex]\frac{8}{6}[/tex] ( cross- multiply )

What is the solution to the following system of equations
4x+2y=6
X-y=3
Answer:
The solution of the equation 4x + 2y = 6 and x − y = 3 will be D. (2, –1)
Step-by-step explanation:
4x + 2y = 6 ....… (1)
x − y = 3 …..... (2)
Example, for equation 2 is:
x - y = 3
x = 3 + y
Put in equation 1:
4(y + 3) + 2y = 6
4y + 12 + 2y = 6
6y = -6
y = -6/6
y = -1
We have the value of y, then the value of x will be:
x = 3 + y
= 3 + (-1)
= 3 - 1
= 2
So, the solution of the equation 4x + 2y = 6 and x − y = 3 will be (2, –1)

Determine the time at which the rocket reaches its maximum height.
a. 2.8 seconds
b. 3.5 seconds
C. 7 seconds
d. 5.6 secands
The time at which the rocket reaches its maximum height is 3.5 seconds. Therefore, b. is the correct answer.
What is function f(x)?An equation describing the relationship between the input (x) and the output (f(x)) is called the function f(x). Any equation that represents the connection between an input x and an output f is referred to as the function f(x) (x).
A function can be expressed as a graph or table in addition to the standard form of an equation. Functions can be stated using symbols and phrases in addition to equations. A function could be expressed, for instance, as "the square of x" or "f of x equals x squared."
Whatever form a function takes, it's critical to keep in mind that the input (x) always yields the same result (f(x)).
In the given question,
The maximum height of the rocket is achieved at the point when the velocity of the rocket is 112 feet. This can be determined by taking the derivative of the function S(t).
S'(t) = 112
Therefore, when S'(t) = 112, t = 3.5.
This means that the rocket reaches its maximum height at t = 3.5 seconds.
Therefore, the time at which the rocket reaches its maximum height is 3.5 seconds.

From the top of a canyon, the angle of depression to the far side of the river is 52°, and the angle of depression to the near side of the river is 71°. The depth of the canyon is 230 feet. What is the width of the river at the bottom of the canyon? Round to the nearest foot.
Trig question
Answer:
49ft
Step-by-step explanation:
Sketching out the problem, we get something like the diagram below. Assuming the canyon makes a roughly 90° angle with the ground, we can see that we have two right-angled triangles formed.
Focusing on the first triangle: since we have the angle, and we know the height of the canyon is 230ft, we can also find the combined width of the ground and river (let's call this y) using cos:
cos38=230/y
0.7880107536=230/y
y=230/0.7880107536= 291.874189467ft
Focusing now on the first triangle: since we have the angle, and we know the height of the canyon is 230ft, we can find the width of the ground (let's call this x) using cos:
cos19=230/x
0.94551857559=230/x
x=230/0.94551857559= 243.252756673ft
Therefore, the width of the river must be the difference between the combined width of the ground and river, minus the width of the ground:
291.874189467ft - 243.252756673ft = 48.621432794ft ≈ 49ft

three vertices of ABCD are A(2,4) b(5,2) c(3,-1) find the coordinates of vertex D
The coordinates of vertex D of the parallelogram is; (0, 1)
How to find the coordinates of a Parallelogram?We are given the coordinates of the parallelogram as;
A(2,4), B(5,2) and C(3,-1)
Now, we know that the diagonals of a parallelogram bisect each other. So, the midpoint of AC is same as the mid point of BD.
The formula for the midpoint between two coordinates is;
(x1 + x2)/2, (y1 + y2)/2
Thus;
Midpoint of AC = (2 + 3)/2, (4 - 1)/2 = 5/2, 3/2
Midpoint of BD = (5 + x)/2, (2 + y)/2
Thus;
(5 + x)/2 = 5/2

Suppose x is the number of times a woman is selected when 3 people are randomly chosen from a group of 2 women and 2 men, the possible values of x are 0, 1, 2, and 3.
When 3 people are randomly chosen without replacement from a group of 2 women and 2 men, there are a total of 4C₃ = 4 possible outcomes, which we can list as follows:
WWx (two women and one of either gender)
WMx (one woman, one man, and one of either gender)
MWx (one man, one woman, and one of either gender)
MMx (two men and one of either gender)
In each of these outcomes, x represents the number of times a woman is selected. We can see that the possible values of x are 0, 1, 2, and 3, depending on which outcome occurs.
In outcome 1 (WWx), a woman is selected twice, so x = 2.
In outcomes 2 (WMx) and 3 (MWx), a woman is selected once, so x = 1.

assume that earth is a sphere with radius 3960 miles a town is at latidtude 32 n find the distance in miles from the town to the north pole
The distance from the town to the North Pole is approximately 2290 miles.
To find the distance in miles from the town to the North Pole, we need to calculate the length of the meridian arc from the town to the North Pole. The meridian arc is a portion of a great circle passing through the town and the North Pole.
The length of the meridian arc can be calculated using the formula:
Length = (π/180) x radius of the Earth x angle in degrees
where π is approximately 3.14159, and the radius of the Earth is 3960 miles.
Since the town is located at latitude 32°N, the angle between the town and the North Pole is 90° - 32° = 58°.
Plugging in these values into the formula, we get:
Length = (π/180) x 3960 miles x 58°
Length = (3.14159/180) x 3960 miles x 58
Length ≈ 2290 miles
Therefore, the distance from the town to the North Pole is approximately 2290 miles.

tan(55) = x/20
Multiplying both sides by 20:
x = 20 tan(55)
