Answer:
b = 6 when a=12 and
c=100
Step-by-step explanation:
b = (k*a)/√c
b=5 when a=2 and c=4
5 = (k*2)/√4
5 = 2k/2
Cross product
5*2 = 2k
10 = 2k
k = 10/2
= 5
k = 5
find b when a=12 and
c=100
b = (k*a)/√c
= (5*12)/√100
= 60/10
= 6
b = 6

Tools of Geometry: Question 10 Quadrilateral ABCD has vertices A = (0, 4), B = (0, 3), C = (3, 0), and D = (3 ,4). Quadrilateral A'B'C'D' is formed when quadrilateral ABCD is reflected over the x-axis. What are the coordinates of quadrilateral A'B'C'D' ? A' = (-4, 0), B' = (-3, 0), C' = (0, 3), and D' = (4, 3) A' = (0, -4), B' = (0, -3), C' = (-3, 0), and D' = (-3, -4) A' = (0, -4), B' = (0, -3), C' = (3, 0), and D' = (3, -4) A' = (0, 4), B' = (0, 3), C' = (-3, 0), and D' = (-3, 4)

Answer:
(c) A' = (0, -4), B' = (0, -3), C' = (3, 0), and D' = (3, -4)
Step-by-step explanation:
Reflection over the x-axis negates the y-coordinate only. The appropriate choice is ...
A' = (0, -4), B' = (0, -3), C' = (3, 0), and D' = (3, -4)

Alisa, Mykia, and Martin decide to share the responsibility of walking their dog every day. There are 365 days in a year. How many days each year does Alisa need to walk the dog?
Answer: 121 2/3 days
Step-by-step explanation:
Number of days in a year = 365 days
Number of friends = 3 friends
The number of days each year that Alisa need to walk the dog will be:
= Number of days in a year / Number of friends.
= 365 / 3
= 121 2/3 days
= 121 days + (2/3 × 24hours)
= 121 days 16 hours
Note that 24 hours = 1 day

Answer:
[tex]b+1\\b+2\\b+(b+1)+(b+2)=24[/tex]
Step-by-step explanation:
If [tex]b[/tex] represents the youngest brother's age, the second oldest brother's age can be written as [tex]b+1[/tex] and the third can be written as [tex]b+2[/tex], since they're all consecutive.
The sum of all their ages is then [tex]b+(b+1)+(b+2)[/tex] which is equal to [tex]24[/tex], as given.

Polygon E’F’G’H’
is a dilation image of the polygon
EFGH
What is the scale factor of the dilation?
A.3
B.6
C.12
D.1/3
Answer:
The scale factor of the dilation is 3 ⇒ A
Step-by-step explanation:
If a polygon dilated by a scale factor k, then the ratio between its sides and the corresponding sides of its image equals k The length of a vertical segment is the difference between the y-coordinates of its endpointsIn the given figure
∵ EFGH is a polygon
∵ E = (-2, 1), H = (-2, -1)
∵ EH is a vertical side
→ By using the 2nd rule above
∴ The length of EH = 1 - (-1) = 1 + 1
∴ The length of EH = 2
∵ E'F'G'H' is its image after dilation by scale factor k
∵ E' = (-2, 5), and H' = (-2, -1)
∵ E'H' is a vertical side
∴ The length of E'H' = 5 - (-1) = 5 + 1
∴ The length of E'H' = 6
→ By using the 1st rule above
∴ [tex]\frac{E'H'}{EH}[/tex] = [tex]\frac{E'F'}{EF}[/tex] = [tex]\frac{H'G'}{HG}[/tex] = [tex]\frac{F'G'}{FG}[/tex] = k
∵ [tex]\frac{E'H'}{EH}[/tex] = k
∵ [tex]\frac{E'H'}{EH}[/tex] = [tex]\frac{6}{2}[/tex]
∴ [tex]\frac{E'H'}{EH}[/tex] = 3
∴ k = 3
∴ The scale factor of the dilation is 3

Step-by-step explanation:
Convert into degrees. 9pi/6
Answer:
270 degrees
Step-by-step explanation:
Take note that to convert Pi to Radians you need to use the formula of
180 degrees = Pi radians
Therefore if you have 180 degrees multiplied by 9 Pi over 6 you get the degree measurement of 270
I believe, The answer to your question is:
B. 270°

Which expression is equivalent to the expression -3 (4r - 2) -2r?
Answer:
-14r + 6
Step-by-step explanation:
-12r + 6 - 2r
find the angle p (add a explanation too)
Step 1: Find the sum of the interior angles
Use this formula: 180 x (n - 2)
n is the number of sides of the polygon
Work:
180 x (4 - 2)
180 x 2
360
Step 2: Find the angle right above the 94 degree angle
The entire angle (a circle) is equal to 360 degrees. To find the part we're looking for (inside of the polygon), we need to subtract the angle we already know from 360.
Work:
360 - 94
266
Step 3: Set up an equation to find the missing angle p
We now know every angle except p! And we know the sum of the interior angles. Knowing this information makes it really easy to set up an equation.
360 = 12 + 75 + 266 + p
360 = 353 + p
p = 7 degrees
Does this answer make sense?
Yes! Although the drawing may not be to scale, it is very possible that angle p could be 7 degrees because of how 12 degrees looks on this graph.
Hope this helps!! :)

The Choir Booster Club had a budget of $1,500 at the start of the school year. They spend $225.30 on t-shirts, $482.25 on lost uniforms, and $135.68 on a holiday party. How much does the booster club have left in their budget?
Answer:
$656.77 is left
Step-by-step explanation:
-$1,500 budget
Spends: $225.30, $482.25, 135.68.
Now subtract all these values with 1,500.
1500 - 482.25 - 225.30 - 135.68 = 656.77

HELP!!!What is the length of BC in the right triangle below
Answer: 39
Step-by-step explanation:
D. 39
Explanation:you use the pythagorean theorem which is [tex]a^{2}+b^{2} = c^{2}[/tex]
if you look at the triangle we can see that we have to find the length of the hypotenuse (BC).
so your equation will look like this:
[tex]15^{2} + 36^{2} =c^{2}[/tex]
Solving For The Length Of BC1. [tex]15^{2} + 36^{2} =c^{2}.[/tex] (solve for [tex]15^{2} and 36 ^{2}[/tex])
2. C= 225+1296 (add)
3. C= 1521 (find the square root of 1521)
4. [tex]\sqrt{1521} = 39[/tex]
Therefore, 39 is your answer

Answer:
x = 10√3
Step-by-step explanation:
The Pythagorean theorem tells you ...
FB^2 = BC^2 +CF^2
FA^2 = FB^2 +BA^2
Substituting for FB^2, we have ...
FA^2 = BC^2 +CF^2 +BA^2 = x^2 +x^2 +x^2
FA^2 = 3x^2
FA = x√3 = 30 . . . . take the square root and substitute for FA
x = 30/√3
x = 10√3
