Find the midpoint M of the line segment joining the points A = (-2, 8) and B = (-8, -4).
Answer:
M (- 5, 2 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = A (- 2, 8 ) and (x₂, y₂ ) = B (- 8, - 4 ) , then
midpoint = ( [tex]\frac{-2-8}{2}[/tex] , [tex]\frac{8-4}{2}[/tex] ) = ( [tex]\frac{-10}{2}[/tex] , [tex]\frac{4}{2}[/tex] ) = (- 5, 2 )

Millie and Molly’s ages add up to 19 years Millie is three years older than Molly how old are they
Answer:
Millie is 11. Molly is 8.
Step-by-step explanation:
Step 1: Subtract 3 from 19. The reason why you do this is to make sure that you don't have an extra 3 lying in there for the next few steps.
19-3=16
Step 2: Divide 2 from 16. You do this because there are two sisters.
16÷2=8
8 will then become Molly's age
Step 3: Add 3 to 8. This will give you Millie's age because she is 3 years older than Molly.
3+8=11
In conclusion, Millie is 11 and Molly is 8.

Answer:
m∠EFD = 90°
m∠EHF = 127°
m∠HFG = 56°
m∠G = 71°
m∠E = 19°
Step-by-step explanation:
From inspection of the given diagram, line segment GD is a straight line and m∠EFG= 90°.
Angles on a straight line sum to 180°:
⇒ m∠EFG + m∠EFD = 180°
⇒ 90° + m∠EFD = 180°
⇒ 90° + m∠EFD - 90° = 180° - 90°
⇒ m∠EFD = 90°
Angles on a straight line sum to 180°:
⇒ m∠EHF + m∠FHG = 180°
⇒ m∠EHF + 53° = 180°
⇒ m∠EHF + 53° - 53° = 180° - 53°
⇒ m∠EHF = 127°
From inspection of the given diagram, m∠EFH and m∠HFG form a right angle:
⇒ m∠EFH + m∠HFG = 90°
⇒ 34° + m∠HFG = 90°
⇒ 34° + m∠HFG - 34° = 90° - 34°
⇒ m∠HFG = 56°
Interior angles of a triangle sum to 180°:
⇒ m∠HFG + m∠GHF + m∠G = 180°
⇒ 56° + 53° + m∠G = 180°
⇒ 109° + m∠G = 180°
⇒ 109° + m∠G - 109° = 180° - 109°
⇒ m∠G = 71°
Interior angles of a triangle sum to 180°:
⇒ m∠E + m∠EFH + m∠EHF = 180°
⇒ m∠E + 34° + 127° = 180°
⇒ m∠E + 161° = 180°
⇒ m∠E + 161° - 161° = 180° - 161°
⇒ m∠E = 19°

Please help me with this I will give lots of points
Answer:
y = -1/2x + 5
Step-by-step explanation:
x + 2y = 10
Step 1: subtract x from both sides.
you will get: 2y = -x + 10
Step 2: get the y by itself, you can do this by dividing 2 by both sides.
= 2y = -x + 10
y = -1/2x +10/2
Then, 10/2 simplifies to 5.
So, your answer is: y = -1/2x + 5
juan compro: 1/4 de pepino que cuesta $3, 1 1/2 de jamón que cuesta $120, 1/3 de tortillas que cuesta $6, 4/8 de queso que cuesta $45. cuanto dinero gasto en total? cuanto cuesta un kilo de queso? cuanto cuesta medio kilo de jamón? ¿Cuánto gastaría si comprara un kilo de tortilla, un kilo de pepino, y un kilo de jamón? si Juan tiene $430 que puede comprar sin que le sobre ni un peso?
En total, Juan gastó $205.25. 1 kilo de queso cuesta $90. 1/2 kilo de jamón cuesta $60. Si comprara un kilo de tortilla, un kilo de pepino y un kilo de jamón, Juan gastaría $129. Si Juan tiene $430, puede comprar 3 kilos de jamón, 1 kilo de queso, 5 kilos de pepino y 1 2/3 de tortillas.
Dado que Juan compró 1/4 de pepino que cuesta $3, 1 1/2 de jamón que cuesta $120, 1/3 de tortillas que cuesta $6 y 4/8 de queso que cuesta $45, para determinar cuánto dinero gastó en total, cuánto cuesta un kilo de queso, cuánto cuesta medio kilo de jamón, cuánto gastaría si comprara un kilo de tortilla, un kilo de pepino, y un kilo de jamón y, si Juan tiene $430, qué puede comprar sin que le sobre ni un peso, se deben realizar los siguientes cálculos:
Cuánto dinero gastó en total = valores x fracción comprada3 x 1/4 + 120 x 1 1/2 + 6 x 1/3 + 45 x 4/8 = X0.75 + 180 + 2 + 22.5 = X205.25 = XSi 4/8 de queso cuestan $45, y 4/8 es igual a 1/2, 1 kilo de queso cuesta $90 (45 x 2).Si 1 kilo de jamón cuestan $120, 1/2 kilo de jamón cuesta $60 (120 / 2).Si comprara un kilo de tortilla, un kilo de pepino y un kilo de jamón, Juan gastaría $129 (3 + 6 + 120).Si Juan tiene $430, puede comprar 3 kilos de jamón, 1 kilo de queso, 5 kilos de pepino y 1 2/3 de tortillas (120 x 3 + 45 + 3 x 5 + 6 + 6 x 0.666).Aprende más en https://brainly.com/question/15723794

Step-by-step explanation:
naomi has earned $54 mowing lawns the past two days .She worked 2.5 hours yesterday and 4.25 hours today .if naomiis paid the same amount for every hour she works ,how much does she earn per hour to mow lawns
Answer:
8$ per hour
Step-by-step explanation
First, we need to find how many hours Naomi worked, total.
Simply add [tex]2.5+4.25=6.75[/tex]
Now we know that Naomi earned 54$ over 6.75 hours.
All we have to do to find the hourly rate is divide [tex]54/6.75=8[/tex]
Naomi earns 8$ per hour mowing lawns.
Answer:
$8
Step-by-step explanation:
Set up an equation with the payrate ($/hr) as the unknown.
2.5 × R + 4.25 × R = 54
6.75 × R = 54 ; R = [tex]\frac{54}{6.75}[/tex] = 8

B) one of them 2 times
C) The ratio of their values is 2:3.
help!!!!!!!!!
hurry up please and tell me about everything please
can someone help me im gonna be late pleasee do it for me my mom gonna kill me if i will got f
Answer:
A angles are 15 and 75 B. angles are 30 and 60 C. angles are 36 and 54
Step-by-step explanation:
Remember that the two acute angles of a right triangle = 90
A one angle = x ; the other angle = 60 + x so 60 +x + x = 90
60 + 2x = 90; 2x = 30; x = 15 one angles; the other angle is 60 + 15 = 75
B. One angle = x ; the other angle = 2x so x + 2x = 90
3x = 90 ; x = 30 one angle; the other angle s 2x = 2(30) = 60
C 2 : 3 means 2x:3x
One angle = 2x ; the other angle = 3x ; so 2x + 3x = 90
5x = 90; x = 18 this is what x is equal to. Now the find the angles:
one angle is 2x meaning 2(18) = 36 and the other angle is 3x meaning 3(18) = 54.
To check this answer one angle to the other angle is represented by the ratio 2:3; 36:54 = 2:3 Reduced!
A 10 -foot ladder is leaning on a tree. The bottom of the ladder on the ground at a distance of 6 feet from the base of the tree. The base of the tree and the ground form a right angle as shown.
What is the distance, in feet, between the ground and the top of the ladder?
The distance, in feet, between the ground and the top of the ladder is 8 feet.
The diagram formed will be a right triangle having the hypotenuse, adjacent and opposite sides
To get the distance, in feet, between the ground and the top of the ladder, we will use the Pythagoras theorem as shown:
hyp² = opp² + adj²Given the following sides
length of ladder = hyp = 10footdistance from ladder to the base = adjacent = 6 feetSubstitute the given parameters into the formula to have:
10² = opp² + 6²
opp²=100 - 36
opp² = 64
opp = 8feet
Hence the distance, in feet, between the ground and the top of the ladder is 8 feet.

Determine the x and y intercepts of the graph of 3x + 4y = 24
Answer:
Step-by-step explanation:
3x + 4y = 24
Find the x intercept by solving intersecting the graph of f(x) or y with
y=0 (which is the x-axis)
4y= -3x+24, subtract 3x from both sides of the equation
y = (-3x/4) +6, divide both sides by 4
if y=0 then
(-3x/4) +6 = 0 , subtract 6 from both sides
-3x/4 = -6, multiply both sides by 4
-3x = -24 , divide both sides by
x= 8, so the x intercept is at (8, 0)
the general formula of a line is y=mx+b , where b is the y-intercept
since our equation is y = (-3x/4) +6 then y intercept is at (0, 6)
