a point on a perpendicular bisector is 7cm from each endpoint of the bisected segment and 5cm from the point of intersection. What is the length of the segment?
Answers
9514 1404 393
Answer:
about 9.80 cm
Step-by-step explanation:
The length of half the segment (h) can be found from the Pythagorean theorem:
h² +5² = 7²
h² = 7² -5² = 49 -25 = 24
h = √24 = 2√6
This is half the segment length, so the whole segment length is ...
L = 2h = 2(2√6)
L = 4√6 ≈ 9.7980
The length of the segment is 4√6 ≈ 9.80 cm.

how to find the value of x in a triangle (5x-11)°, (2x+20)°, (11x-63)°
Answers
Answer:
x=13
Step-by-step explanation:
Well, the triangle is always equal to 180 degrees in total. Lets remember that x will always be the same in every equation.
So, (5x-11) x (2x+20) x (11x-63) = 180.
Now, take away the parenthesis and add up all the like terms.
This should = 18x-54 = 180.
Now solve like you regularly would. Add 54 on both sides which equals,
18x=234. Now, divide 18 on both sides.
x = 13.
Hope this helps.
x=13
Explanation:
All the angles in a triangle add up to 180 degrees, and this is true for every and any triangle. Knowing this, we can set up this equation and solve:
(5x-11)+(2x+20)+(11x-63)=180
1) Open up parentheses
5x-11+2x+20+11x-63=180
2) Combine like terms
5x+2x+11x-11+20-63=180
18x-54=180
3) Add both sides by 54
18x-54+54=180+54
18x=234
4) Divide both sides by 18
18x/18=234/18
x=13
I hope this helps!

Sue makes bracelets. She uses

4
inches of chain to make one bracelet. How many bracelets can she make from a chain that is
49
1
2
inches long?
Answers
9514 1404 393
Answer:
6
Step-by-step explanation:
We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:
6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2
Sue can make 6 bracelets.
_____
You can also divide the total length of chain by the amount per bracelet:
(49 1/2)/(8 1/4) = (99/2)/(33/4)
= (99/2)(4/33) = (99/33)(4/2)
= (3)(2) = 6
Answer:
6
Step-by-step explanation:
We estimate the number as 49/8 ≈ 6. We can check to see if this is too many by finding the chain required for 6 bracelets:
6 × 8 1/4 = 6×8 +6×1/4 = 48 +6/4 = 49 1/2
Sue can make 6 bracelets.
_____
You can also divide the total length of chain by the amount per bracelet:
(49 1/2)/(8 1/4) = (99/2)/(33/4)
= (99/2)(4/33) = (99/33)(4/2)
= (3)(2) = 6

Step-by-step explanation:
equation: y = x - 6 + x^2
(6,0) (7,1) (8,4) (9,9)
I figured this out by looking at the point (6,0). To get 0 (y), you have to subtract 6. Knowing this, I subtracted 6 from the rest of the coordinates, leaving me with numbers that are able to be squared to get y. This led me to the equation x - 6 + x^2.

Step-by-step explanation:
'one' 50 cents, other 10 cents
If you get 50 cents you have to roll other number 5 times to minus 50 cents (50 divided by 10 is 5)
because they got nothing after roll so if they get a cents they have to minus it rolling other number
So if you divide 30 (the number of rolling) by 5 (the number of times to minus 50 cents) so the answer will be 6

Wilmer went up a hill for x minutes at a speed of y kilometers per minutes. Then he went down the same path at a speed of z kilometers per minute, and it took him w minutes to do it. Write an equation that relates x, y, z, and w. (The wording for this question really confuses me. And I do not understand which variable to put on it's own.) PLEASE ANSWER
Answers
Answer:
[tex]xy=wz[/tex]
Step-by-step explanation:
Given that:
Speed of Wilmer up the hill = [tex]y[/tex] km/min
Time taken up the hill = [tex]x[/tex] minutes
Speed of Wilmer down the hill = [tex]z[/tex] km/min
Time taken up the hill = [tex]w[/tex] minutes
Distance can be calculated by multiplying the Speed with Time i.e.
The formula for distance is given as:
[tex]Distance = Speed \times Time[/tex]
Distance up the hill = [tex]y\times x =xy\ kilometers[/tex]
Distance down the hill = [tex]z\times w =wz\ kilometers[/tex]
It is well known that, the distance up the hill and down the hill will be same.
Putting both the values equal, we get:
[tex]xy=wz[/tex]

Please answer.
Answers
Answer:
x = 15
Step-by-step explanation:
Given
5x + 55 = 2x + 100 ( subtract 2x from, both sides )
3x + 55 = 100 ( subtract 55 from both sides )
3x = 45 ( divide both sides by 3 )
x = 15
Subtract 2x from Both sides and subtract 55 from both sides so that’ll be 3x=45 divide both sides by 3 and get 15
