The term that completes the equation is YZ.
Option D is the correct answer.
We have,
From the figure,
∆WXY and ∆XYZ
∠WXY = ∠XZY = 90
∠ZYX = ∠XYW (common angle)
∆WXY ≅ ∆XYZ
And,
∆WXY and ∆WXZ
∠WXY = ∠WZX = 90
∠YWX = ∠XWZ (common angle)
∆WXY ≅ ∆WXZ
Now,
From (1) and (2),
∆XYZ ≅ ∆WXZ
This means,
The corresponding sides are proportional.
We can write as,
YZ/XZ = XZ/ZW
XZ² = WZ x YZ
Thus,
The term that completes the equation is YZ.

[tex]\frac{x}{7}[/tex] − [tex]\frac{x}{9}[/tex] =−1
Answer:
[tex]x = \frac{ - 63}{2} \: or \: - 31.5[/tex]
Step-by-step explanation:
[tex] \frac{x}{7} - \frac{x}{9} = - 1[/tex]
Lets take the L.C.M of 7 & 9.
L.C.M of 7 & 9 = 63
[tex] = > \frac{9x - 7x}{63} = - 1[/tex]
[tex] = > \frac{2x}{ 63} = - 1[/tex]
Now lets multiply 63 on both the sides.
[tex] = > \frac{2x}{ 63} \times 63 = (- 1) \times 63[/tex]
[tex] = > 2x = - 63[/tex]
Now lets divide both the sides by 2.

[tex] = > x = \frac{ - 63}{2} = - 31.5[/tex]
The movie club is having a new member sale, so Mindy signs up. The equation -0.4x + 0.05y - 1.25 = 0 relates y, the total cost, and x, the number of months. What is the y-intercept of the line represented by the equation?
Answer:
Y intercept : ( 0 , 25 )
Step-by-step explanation:
Answer:
(0, 25)Step-by-step explanation:
We need to convert function to slope-intrcept form y=mx+b, where:
-0.4x + 0.05y - 1.25 = 0 {multiply both sides by 20}
-8x + y - 25 = 0 {add (8x+25) to both sides}
y = 8x + 25 ⇒ b = 25
Therefore y-intercept of the line is (0, 25)

How do I find the missing side length for 30 - 60 - 90 method as a radical in simplest form?
Answer:
Step-by-step explanation:
see the image below
Step-by-step explanation:
The side that is adjacent to 60 degree and 90 degree is the shortest side.
If u know the hypoutnese you can divide it by 2 to find the shortest side. for example if the hypotenuse is 10 then the shortest side is 5
If you know the other leg you can simply just remove the entire radical and just keep the whole number to find the length of the shortest side.
The side that his the adjacent to the 30 degree and 90 degree angle is the second longest side of the triangle.
If u know the shortest side, just multiply the radical
[tex] \sqrt{3} [/tex]
to the whole number.
If you know the hypotunese, divide the hypotenuse by 2 and then multiply the radical to find the length of the second shortest side
Finally, the hypotunese is the largest side. It is the slanted side length that is adjacent to the 30 and 60 triangle.
If you know the shortest side, just multiply the side length by 2 to get the hypotenuse.
If you know the other leg, remove the radical and keep the who the number and multiply the whole number by 2.
E.x if the second longest side length is
[tex]5 \sqrt{3} [/tex]
Remove the radical so it becomes
[tex]5[/tex]
then multiply it by two to find the hypotunese.
[tex]5 \times 2 = 10[/tex]

Answer:
a = 45
Step-by-step explanation:
Start by changing the fractions so they share a common denominator to combine like-terms:
6/10a - 5/10a = 9/2
1/10a = 9/2
Multiply both sides by 10 to isolate a.
a = 90/2

8x + 20 ° = 180°
8x = 180° - 20°
8x = 160°
x = 160° / 8

The triangle shown below are similar. Solve for x. 
Answer:
x=16
Step-by-step explanation:
27/45=(2x+7)/(4x+1)
cross multiply
27(4x+1)=45(2x+7)
108x+27=90x+315
108x-90x=315-27
18x=288
x=288/18
x=16
Looking at the image, The triangle shown below are similar. The value for x is 16.
What is the triangle about?Note that in the triangle given, the shapes are similar. Therefore:
27/45 = 2x + 7/ 4x + 1
3/5 = 2x + 7/ 4x + 1
So:
3 (4x + 1) = 5 (2x + 7)
12x + 3 = 10x + 35
12x - 10x = 35-3
2x = 32
x = 32/ 2
x = 16
Therefore, the value of x is 16.

The population of a city decreases by 1.6% per year. If this year's population is 320,000, what will next year's population be, to the nearest individual?
Answer:
314,880
Step-by-step explanation:
If the population decreases by 1.6% per year, this means the population is 98.4% of the population of the previous year. What this means is we can multiply the current population, 320,000, by 98.4/100, as 98.4/100 is equivalent to 98.4%. This gets us 314,880.

Answer:
c on edge
Step-by-step explanation:
just took the quiz
The equation representing the circle A is (x – 4)² + (y + 5)² = 36.
What is circle?A circle is a spherical shape without boundaries or edges. A circle is a closed, curved object with two dimensions in geometry.
The general equation of circle is given by equation
( x - h )² + ( y - k )² = r²
Where, ( h, k ) is the centre and 'r' is the radius.
As, the circle has a shift of 4 units on the +x axis.
The circle has a shift of the 5 units on the -y axis.
As, the circle has a radius of 6 units from the graph.
So, (h,k) = (4, -5).
Substitute the values of (h,k) in the general equation of the circle.
( x - 4 )² + ( y - (-5) )² = 6²
( x - 4 )² + ( y + 5 )² = 36
Therefore, the equation of circle becomes ( x - 4 )² + ( y + 5 )² = 36.
