In triangle ACE, G is the centroid and BE = 18. Find BG and GE.
a BG=12, GE=6
b BG=4 1/2, GE=13 1/2
c BG=6, GE=12
d BG=9 GE=9
Answers
Answer: Choice C) BG = 6, GE = 12
=======================================================
Explanation:
The centroid G cuts the median segment BE such that BG is 1/3 of BE, and GE is 2/3 of BE.
So,
BG = (1/3)*BE = (1/3)*18 = 6
GE = (2/3)*BE = (2/3)*18 = 12
-------------
Put another way: GE is twice as long as BG
Let x = BG. This means 2x = GE
Leading to
BG+GE = BE
x+2x = 18
3x = 18
x = 18/3
x = 6 = BG
2x = 2*6 = 12 = GE

Answer:
2×5×11 = 110
Step-by-step explanation:
The factors are separated by the × (multiplication) sign. Common factors are numbers that are factors of both products.
It can be useful to list the factors in order of size, for easier comparison.
1st product:
2 × 3² × 5² × 11 × 17
2nd product:
2 × 5 × 7 × 11² × 13²
Ignoring exponents (for the moment), the numbers that appear in both products are 2, 5, 11. (I've highlighted them so you can see them more easily.)
Now, we consider the exponents. We want to determine the lowest exponent of each of these factors.
2 has the same exponent in both products: 1
5 has exponents of 2 and 1. The least of these is 1.
11 has exponents of 1 and 2. The least of these is 1.
So, the greatest common factor (GCF) is ...
2¹ × 5¹ × 11¹ = 2×5×11 = 110 . . . . greatest common factor
(Comment on answer format: the given numbers are shown as a product of factors. It is not clear whether the desired answer format should match, or should have the value multiplied out. We have shown both ways.)
_____
Check
If we factor out the "greatest common factor," the given products can be written as ...
(2×5×11) × (3² × 5 × 17)
(2×5×11) × (7 × 11 × 13²)
You will notice that the right factors of each of these products have nothing in common. So, we have found the greatest common factor.

Is the Point on the Line?
Answers
Answer:
yes.
Step-by-step explanation:
The eqation of the line is y=1/2x+3 so when we plug in x as 20 y is equal to 13
Answer:
Yes it is on the line becuase if you find the slope of the line which is 1/2. We can just use rise over run from there. So we know 1 is y and 2 is x Becuase slope is written in y/x. And we can fins slope by just calculating the rise over run or suing the formula y2-y1/x2-x1. So the last pont shown on the line is (10,8) so we can add 1 to the y or in this case 8 and add 2 to the x or in this case 10. You’ll get (12,9). We know this works becuase if you find the slope of (12,9) and (10, 8), you’ll get 1/2 again which is the same slope so we know it’s right. Now we just add using the same slope to the now new point. We add 1 to 9 and add 2 to 12. (14,10). Still, if you find the slope, it’ll still be 1/2. Now keep repeating that and you’ll get (20, 13) eventually. And we can check by calculating the slope. (20,13) and (10,8), you could use any point on the coordinate plane/ and you’ll get 1/2. A easier way could just be calculating the slope first and you’ll get 1/2 from any two points and then use any two points to calculate the slope for (20,13). It’ll still be the same thing.

Answer:
y = [tex]\frac{1}{2}[/tex] x + 4
Step-by-step explanation:
Assuming you require the equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (8, 8) and (x₂, y₂ ) = (10, 9)
m = [tex]\frac{9-8}{10-8}[/tex] = [tex]\frac{1}{2}[/tex] , then
y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (8, 8) , then
8 = 4 + c ⇒ c = 8 - 4 = 4
y = [tex]\frac{1}{2}[/tex] x + 4 ← equation of line
Write an equation of the line in slope-intercept form given the slope is 2 and the y-intercept is -5.

a circle with a radius 3 centimeters is cut from square piece of felt. the side of the felt square are 8 centimeters long. How much felt is left over? use 3.14 for (pie symbol). show your work.
Answers
Answer:
There are [tex]35.74\ cm^2[/tex] of felt left over.
Step-by-step explanation:
The side of the felt square is 8 cm. A circle of radius 3 cm is cut from the square piece of felt.
The portion of felt leftover is the difference between the area of the square and the area of the circle.
The area of the square is:
[tex]A_s=(8\ cm)^2=64\ cm^2[/tex]
The area of the circle is:
[tex]A_c=\pi(3\ cm)^2=3.14*9\ cm^2[/tex]
[tex]A_c=28.26\ cm^2[/tex]
The remaining area of the piece of felt is:
[tex]A=64\ cm^2-28.26\ cm^2[/tex]
[tex]A=35.74\ cm^2[/tex]
There are [tex]35.74\ cm^2[/tex] of felt left over.
Let x represents a length in cm where x > 1.5.
AB = 2x - 3, BC = 4x – 6,
AD = 2x + 3 and BE = 4x +1
• ABC is right triangle of area Sı.
. CBFG is a rectangle of area S2.
• ADEB is a right trapezoid of area S3.
1) Express S1, S2 and S3 in terms of x.
2) Let S = S1 + S2 -S3.
Answers
Answer:
1) S1 = 4·x² - 12·x + 9
S2 = 12·x² - 26·x + 12
S3 = 6·x² - 5·x - 6
2) S = 10·x² - 33·x + 27
Step-by-step explanation:
The length x in cm > 1.5
Segment AB = 2·x - 3, segment BC = 4·x - 6, segment AD = 2·x + 3 and segment BE = 4·x + 1
1) a) The area of the right triangle ABC = S1 = 1/2 × Base × Height
The base of the triangle ABC = Segment BC = 4·x - 6
The height of the triangle ABC = Segment AB = 2·x - 3
Therefore, The area of the triangle ABC = S1 = 1/2 × (4·x - 6) × (2·x - 3) = 1/2 × (8·x² - 12·x - 12·x + 18) = 4·x² - 12·x + 9
S1 = 4·x² - 12·x + 9
b) The area of the rectangle CBFG = S2 = Base × Height
The base of the rectangle CBFG = BC = 4·x - 6
The height of the rectangle CBFG = BF = 3·x - 2
The area of the rectangle CBFG = S2 =(4·x - 6) × (3·x - 2) = 12·x² - 8·x - 18·x + 12
The area of the rectangle CBFG = S2 = 12·x² - 26·x + 12
S2 = 12·x² - 26·x + 12
c) The area of the trapezoid ADEB = S3 = 1/2 × (Long side + Short side) × The height of the trapezoid ADEB
The long side of the trapezoid ADEB = BE = 4·x + 1
The short side of the trapezoid ADEB = AD = 2·x + 3
The height of the trapezoid ADEB = AB = 2·x - 3
The area of the trapezoid ADEB = S3 = 1/2 × (4·x + 1 + 2·x + 3) × (2·x - 3) = 6·x² - 9·x + 4·x - 6
∴ The area of the trapezoid ADEB = S3 = 6·x² - 5·x - 6
S3 = 6·x² - 5·x - 6
2) S = S1 + S2 - S3 = 4·x² - 12·x + 9 + 12·x² - 26·x + 12 - (6·x² - 5·x - 6) = 10·x² - 33·x + 27

Step-by-step explanation:
Remove parentheses and distribute -4 and -9, calculate the difference, move the variable and constant, collect like terms. ( -2x [tex]\leq[/tex] 4), and divide both sides, and you'll end with -2.
Answer:
x > -2 (last choice)
Step-by-step explanation:
Using the distributive property multiple -4 to both integers
-24 - 20x - 7 < -18x - 27
-31 - 20x < -18x - 27
Add 27 on both sides
-4 - 20x < -18x
Add 20x on both sides
-4 < 2x
Divide each side by 2

The triangle is a right angled triangle, whose one side is 26 and another side is X. It has also one angle that is 41°.
Now, taking reference angle as angle 41°. We get;
Perpendicular= 26
Base = X
and Reference angle = 41°.
We know that the ratio of tan is p/b. So, let's use this ratio.
[tex] \tan(41°) = \frac{26}{x} [/tex]
[tex]0.869 \times x = 26[/tex]
[tex]x = \frac{26}{0.869} [/tex]

If she uses 6 eggs, how many potatoes will she need?
Eggs = 6
Potatoes = x
2 : 5 = 6 : x
2 / 5 = 6 / x
Cross product
2 * x = 5 * 6
2x = 30
x = 30 / 2
x = 15

Credit card A has an APR of 27.2% and an annual fee of $96, while credit card B has an APR of 30.3% and no annual fee. All else being equal, which of these equations can be used to solve the principal P for which the cards offer the same deal over the course of a year
Answers
Answer: D. P * (1 + 0.272/12)¹² + 96 = P * (1 + 0.303/12)¹²
Step-by-step explanation:
Credit Card A deal over the course of a year:
Payments are done per month so values need to be converted to monthly figures.
APR per month = 27.2%/12
Period = 1 year * 12 months = 12
= P * (1 + 27.2%/12)¹² + 96
Credit Card B deal over a year
= P * (1 + 30.3%/12)¹²
The Principal that will enable both cards to offer the same deal will therefore be:
P * (1 + 27.2%/12)¹² + 96 = P * (1 + 30.3%/12)¹²

Answer:
AY = 16
IY = 9
FG = 30
PA = 24
Step-by-step explanation:
The centroid of the triangle divides each median at the ratio 1: 2 from the base
Let us solve the problem
In Δ AFT
∵ Y is the centroid
∵ AP, TI, and FG are medians
→ By using the rule above
∴ Y divides AP at ratio 1: 2 from the base FT
∴ AY = 2 YP
∵ YP = 8
∴ AY = 2(8)
∴ AY = 16
∵ PA = AY + YP
∴ AP = 16 + 8
∴ AP = 24
∵ Y divides TI at ratio 1: 2 from the base FA
∴ TY = 2 IY
∵ TY = 18
∴ 18 = 2
→ Divide both sides by 2
∴ 9 = IY
∴ IY = 9
∵ Y divides FG at ratio 1:2 from the base AT
∴ FY = 2 YG
∵ FY = 20
∴ 20 = 2 YG
→ Divide both sides by 2
∴ 10 = YG
∴ YG = 10
∵ FG = YG + FY
∴ FG = 10 + 20
∴ FG = 30
