Given:
In triangle ABC, Q is the centroid and FQ=9.
To find:
The length of FC and QC.
Solution:
We know that, centroid is the intersection point of medians of a triangle and medians divide teach other in 2:1. So, centroid divided each median in 2:1.
CF is a median and Q is the centroid. So,
[tex]QC:FQ=2:1[/tex]
Let the length of QC and FQ are 2x and x respectively.
We have, FQ=9.
[tex]x=9[/tex]
Now,
[tex]QC=2x[/tex]
[tex]QC=2(9)[/tex]
[tex]QC=18[/tex]
And,
[tex]FC=FQ+QC[/tex]
[tex]FC=9+18[/tex]
[tex]FC=27[/tex]
Therefore, the length of FC is 27 units and length of QC is 18 units.

What is the solution(s) to the equation 5a2 - 44 = 81?
A
+25
B
-5
55
D
1125
Answers
Answer:
B
Step-by-step explanation:
5a^2 - 44 = 81 Add 44 to both sides
5a^2 = 81 + 44 Collect like terms
5a^2 = 125 Divide both sides by 5
a^2 = 125/5
a^2 = 25 Take the square root of both sides
√a^2 = √25
a = +5
a = -5
The answer is B

Findx.
Assume the middle line is a midsegment in the problems below:
HELPPPPPP
Answers
Answer: x = 12
midsegment is 16 units long
bottom side is 32 units long
===============================================
Work Shown:
The midsegment 2x-8 is parallel to the bottom side 2x+8
The bottom side is twice as long compared to the midsegment (since the midsegment is half the length of the bottom side).
We can say
bottom side = 2*(midsegment)
2x+8 = 2*(2x-8)
2x+8 = 4x-16
2x-4x = -16-8
-2x = -24
x = -24/(-2)
x = 12
--------------------
Extra info:
Now that we know x, we can find the length of those segments
midsegment = 2x-8 = 2*12-8 = 24-8 = 16
bottom side = 2x+8 = 2*12+8 = 24+8 = 32
Note the bottom side (32) is exactly twice as long compared to the midsegment (16). This confirms we have the correct x value.

Afla cate procente reprezinta numarul a din numarul b daca a si b sunt invers proportionale cu numerele 12 si 15
Answers
Răspuns:
125%
Explicație pas cu pas:
a și B sunt invers proporționale cu numerele 12 și 15
Proporționalitate inversă:
a = k / y
Prin urmare ;
a = k / 12 - - - (1)
b = k / 15 - - - (2)
Procent care reprezintă a de la b
a = 100%
b = x
k / 12 = 1
k / 15 = x
Înmulțirea încrucișată:
x * k / 12 = k / 15
x = k / 12 ÷ k / 15
x = k / 12 * 15 / k
x = 15/12
x = 1,25
1,25 * 100% = 125%
Warren drank 4 5 liter of water Monday before going jogging. He drank 2 3 liter of water after his jog. How much water did Warren drink altogether? Write your answer as a mixed number.
Answers
Answer: Warren drank 1 7/15 Liters of water altogether
Step-by-step explanation:
Step 1
Amount of water drank before jogging = 4/5 liters
Amount of water drank after jogging =2/3 liters
Amount of water drank altogether =Amount of water drank before jogging +Amount of water drank after jogging
Step 2
Amount of water drank altogether = 4/5 + 2/3
The LCM of 5 and 3 gives 15 , so we have the denominator becoming 15,
4/5 + 2/3 = / 15
15 divided by 5 gives 3 multiplied by 4 gives us 12 and also 15 divided by 3 gives 5 multiplied by 2 gives 10 , such that we have
12 + 10 / 15
= 22/ 15
=1 7/15

The ratio of adult dogs to puppies on monday was 3:2. There were 12 puppies there that day. Tuesday, 15 adult dogs were at the park. How many adult dogs were at the park on monday? What is the difference between the number of adult dogs at the park on monday and tuesday
Answers
Answer:
3
Step-by-step explanation:
The ratio of adult dog to puppies is 3:2
There were 12 puppies that day
Number of adult puppies can be calculated as follows
= 3/2× 12
= 3 ×6
= 18
There were 15 adult dogs in the park on Tuesday
Hence the difference can be calculated as follows
= 18-15
= 3
