in triangle ABC with vertices A(4,5),B(-2,1) and C(0,3),E and F are midpoints of sides AB and AC resp . then, find coordinates of E and F
Answer:
The answer is
E=(1, 3)
F=(2,4)
Step-by-step explanation:
When E is midpoint of AB
Then
[tex]e = ( \frac{4 + ( - 2)}{2} . \frac{5 + 1}{2} ) \\ = (1.3)[/tex]
By this way we can find F
[tex]f = ( \frac{4 + 0}{2} . \frac{5 + 3}{2} ) \\ = (2.4)[/tex]

(PLEASE ANSWER FOR BRAINILEST ASAP!!) (EXPLAIN!!) 3 boxes all way the same amount. All together they weigh 54.3 pounds. How much does 1 box weigh?
Answer:
Step-by-step explanation:
Let B = the weight of box B
Let 2B = the weight of box A
Let 2B + 30 = the weight of box C
B + 2B + 2B + 30 = 640
5B = 610
B = 122 pounds, weight of box B
2B = 2(122) = 244 pounds, weight of box A
2B + 30 = 2(122) + 30 = 274 pounds, weight of box C
Noah and Lin are marketing paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?
if h=3, then r=
if r=2, then h=
Answer: r = 1.69 inches
h = 2.15 inches
Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.
Volume of a cone is directly proportional to radius and height:
[tex]V=\frac{1}{3}\pi r^{2}h[/tex]
They want the cones to hold the same volume of 9 cubic inches.
If height is 3:
[tex]9=\frac{1}{3}\pi r^{2}3[/tex]
[tex]\pi r^{2}=9[/tex]
[tex]r^{2}=2.864[/tex]
r = 1.69 inches
When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.
If radius is 2:
[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]
[tex]h=\frac{9(3)}{4 \pi}[/tex]
h = 2.15 inches
If radius is 2 inches, height of the cone is 2.15 inches.

1st one x=245°
2nd one x= 250
Step-by-step explanation:
hope its correct
hope u find it helpful
Answer:
x = 245 and x = 20
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
Sum the interior angles and equate to 540
25 + 112 + 100 + 58 + x = 540
295 + x = 540 ( subtract 295 from both sides )
x = 245
---------------------------------------------------------------
5x + 2 + 3x + 5 + 8x + 8 + 4x + 15 + 5x + 10 = 540
25x + 40 = 540 ( subtract 40 from both sides )
25x = 500 ( divide both sides by 25 )
x = 20

Answer:
(5a²+4b³)³= 64b^9+240a^2b^6+300a^4b^3+125a^6
(2xy-1)³= 8x^3y^3−12x^2y^2+6xy−1
(3m-2n)= 0
(f+5)³= f^3+15f^2+75f+125
Step-by-step explanation:
(5a²+4b³)³ = [tex]64b^{9} + 240a^{2} b^{6} + 300a^{4} b^{3} + 125a^{6}[/tex]
(2xy-1)³ = [tex]8x^3y^3 - 12x^2y^2 + 6xy - 1[/tex]
(3m-2n) = 3m - 2n
(f+5)³ = [tex]f^3 + 15f^2 + 75f + 125[/tex]

Answer:
P(9,2) = 72
Step-by-step explanation:
Solve the simultaneous equations
5x + 3y = 41
2x + 3y = 20
Do not use trial and improvement
The solution to the system of equation is (7, 2)
Using the simultaneous equation:
5x + 3y = 41
2x + 3y = 20
using elimination method
Subtract equation 1 from 2 to have:
5x - 2x = 41 - 20
3x = 21
x = 21/3
x = 7
Substitute x = 7 into equation 1 to get y
5x + 3y = 41
5(7) + 3y = 41
35 + 3y = 41
5y = 41 - 35
3y = 6
y = 6/3
y = 2
Hence the solution to the system of equation is (7, 2)
