Step-by-step explanation:
For question 30, the first choice is not necessarily true. I attached a picture of what *could* be the parallelogram.
The first choice is true ONLY if the parallelogram is a square.
The second choice is not necessarily true either. It is true ONLY if the parallelogram is a rhombus (a square is also a rhombus, just for reference)
But opposite sides of a parallelogram are always equal
So the answer to question 30 are the first and second choices.
For question 31:
remember what I said about how opposite sides of a parallelogram are always equal? Well opposite angles are also always equal.
So angle BKX = angle BWX = angle XWB = 114 degrees
Angle BKW = angle XWK (using parallel lines) = angle XWB - angle BWK = 114 - 22 = 92 degrees
Angle WBX = angle BXK (using parallel lines too) = angle WXK - angle WXB.
Consecutive angles in a parallelogram add up to 180. So angle WXK + angle XWK = 180. angle WXK = 180 - angle XWK = 180 - 114 = 66 degrees.
angle WDB + angle WBX + angle BWK = 180 because it's a triangle
angle WDB + 66 (just figured it out) + 22 (given) = 180 degrees
angle WDB = 180 - 66 - 22 = 92 degrees
I hope I didn't do anything wrong lol
but I prolly did XD
Answer:
angle WDB + angle WBX + angle BWK = 180 because it's a triangle
angle WDB + 66 + 22 (given) = 180 degrees
angle WDB = 180 - 66 - 22 = 92 degrees
Step-by-step explanation:
Please help me on this quick the work is due today
Answer:
1. 52 degrees 2. D
Step-by-step explanation:
1. The interior angles of a triangle add up to 180, so you can do 180 - 36 - 92 to find the third angle.
180 - 36 - 92 = 52 degrees
2. the angle XYZ has to equal the sum of the angles WXY and XWY. This means that 115 = 45 + XWY
115 - 45 = 72
XWY = D. 70 degrees
can someone help me on the steps for this?

Step 1: Identify
a = 12
b = 5
c = x
Step 2: Solve for x
Substitute in variables [PT]: 12² + 5² = x²Evaluate exponents: 144 + 25 = x²Add: 169 = x²[Equality] Square root both sides: ±13 = xRewrite: x = ±13Since we are dealing with positive numbers, we can disregard the negative root.

One of the longest tape worms ever measured was 3 feet less than seven times the length of the longest round worm ever measured if you leave these two worms and two and they would measure an amazing 69 feet how long with a tapeworm and how long was around worm
Answer:
The tape worm is 60 feet long, while the round worm is 9 feet long.
Step-by-step explanation:
Let L be the length of the tapeworm and L' be the length of the round worm.
Given that the longest tape worms measured was 3 feet less than seven times the length of the longest round worm, we have
L = 7L' - 3 (1)
Also, since if you leave these two worms and they would measure an amazing 69 feet, then L + L' = 69 (2)
Substituting equation (1) into (2), we have
L + L' = 69
7L' - 3 + L' = 69
collecting like terms, we have
8L' = 69 + 3
8L' = 72
L' = 72/8
L' = 9 feet
Substituting L' into (1), we have
L = 7L' - 3
L = 7(9) - 3
L = 63 - 3
L = 60 feet.
So, the tape worm is 60 feet long, while the round worm is 9 feet long.
Solve for b in the formula A=1/2h (B+b)
solve for x
x - 8 = sqrt2x+8
Answer:
x=4
Step-by-step explanation:
to get rid of the square root on the right you square both sides so
2x+8=x^2
Then bring
2x+8
to the left so you have 0=(x^2)−2x+8
Now you can do the quadratic formula to find the zeroes
Answer:
x = {14, 4}Step-by-step explanation:
Given equation:
x - 8 = √2x+8Square both sides
(x - 8)² = (√2x+8)²x² - 16x + 64 = 2x + 8x² - 18x + 56 = 0x² - 2*9x + 81 = 25(x - 9)² = 5²x - 9 = ± 5x = 9 ± 5x = 14 or x = 4help meh for brainlist

A guy wire connects the top of a 18 3/4 foot tall tornado siren to the ground where Samson's shadow ends. The distance from the base of the siren pole to where the wire touches the ground is 120 feet. If Samson is 6 1/4 feet tall and his head barely touches the guy wire where he is standing, how long is Samson's shadow?
Answer:
40 feet
Step-by-step explanation:
Required:
Find the length of Samson's shadow
The question can be illustrated with the attached figure where Samson's shadow is represented with x.
To solve for x, we make use of the following equivalent ratios:
[tex]18.75 : 120 = 6.25 : x[/tex]
Convert to fraction
[tex]\frac{18.75}{120} = \frac{6.25}{x}[/tex]
Cross Multiply
[tex]18.75 * x = 120 * 6.25[/tex]
[tex]18.75 * x = 750[/tex]
Make x the subject
[tex]x =\frac{750}{18.75}[/tex]
[tex]x =40[/tex]
Hence, Samson's shadow is 40ft
Rafael rented a truck for one day. There was a base fee of $14.99, and there was an additional charge of 87 cents for each mile driven. Rafael had to pay
S255.98 when he returned the truck. For how many miles did he drive the truck?
Answer: Rafael drove 277 miles
Step-by-step explanation:
255.98 - 14.99 = 240.99
240.99 / .87 = 277.

Solve the radical equation [tex]\sqrt{2-x} = x-2[/tex]
Answer:
x = 1 or 2
Step-by-step explanation:
[tex] \sqrt{2 - x} = x - 2[/tex]
Squaring both the sides ,
[tex] = > { (\sqrt{2 - x}) }^{2} = {(x - 2)}^{2} [/tex]
[tex] = >2 - x = {x}^{2} - 4x + 4[/tex]
Adding like terms ,
[tex] = > {x}^{2} - 4x + x + 4 - 2 = 0[/tex]
[tex] = > {x}^{2} - 3x + 2 = 0[/tex]
Factorising the eqn. ,
[tex] = > {x}^{2} - x - 2x + 2 = 0[/tex]
[tex] = > x(x - 1) - 2(x - 1) = 0[/tex]
[tex] = > (x - 1)(x - 2) = 0[/tex]
Here x will have 2 values .
1) [tex]x - 1 = 0[/tex]
[tex] = > x = 1[/tex]
2) [tex]x - 2 = 0[/tex]
[tex] = > x = 2[/tex]
find the slope of the line hurry!
Answer:
the slope is 3 :)
Step-by-step explanation:
Answer:
the slope is: 3
you find two points where the line crosses directly on a point, (2,2) and (5,3)
and count how many spaces upwards and how spaces to the right. slope is rise/run meaning the spaces upward is the numerator and the spaces right is the run. (if you have to count downward then that's a negative number, and if you have to count left, it's negative) but, this graph has a rise of 3 and a run of 1 or 3/1 or simplified to 3

Step-by-step explanation:
When solving this system of equations using linear combination, what should you do FIRST?
{−x+y=−11
{2x+y=19
A) Solve the first equation for y.
B) Multiply the first equation by -1.
C) Multiply the first equation by -2.
D) Add the two equations together.
Answer:
Multiply the first equation by -1
Step-by-step explanation:
Here, we ware being asked the step to take to solve the simultaneous equation
What is right here is to multiply the first equation by -1
By multiplying the first equation by -1, we will have it that the value of y in that equation becomes negative
It is from here we can now add both equations together to have only real x terms

All you need to do is find the answer for all of them and see which ones match
Original:
6 + (-4) - 5
6 - 4 - 5
2 - 5
-3
This is the answer for the original expression, now we need to see which one is the correct match....
A. -(-6 + 4 ) - 5
2 negatives being subtracted gives you a positive
6 + 4 - 5
10 - 5
5
Incorrect, so now we know its not A
B. 6 - 4 - ( -5)
Again 2 negatives give you a positive
6 - 4 + (5)
6 - 9
-3
Correct, so now we know its B
C. 6 - (4 + 5)
PEMDAS so do the parenthesis first
6 - 9
-3
Correct, so now we it's C.
D. 6 + 4 - 56
10 - 56
-46
Incorrect, so now we know its not D
E. -(-6) + (-4) - (-5)
Again, 2 negatives equal a positive
6 - 4 + 5
2 + 5
7
Incorrect so now we know its not E
The correct answer is C

Meteorologists find the height of a cloud using an instrument called a
ceilometer. A ceilometer consists of a light projector that directs a
vertical light beam up to the cloud base and a light detector that scans
the cloud to detect the light beam.
If the angle O is 40° and the distance (Base b) between the projector
and detector is 8000 feet how high are the clouds above the ground to
the nearest foot?
