Answer:
65 marbles
Step-by-step explanation:
2:6 = x-20:x using the information in the problem
2x = 6x-120, and therefore x = 30. 30 is the number of green marbles.
We can find that the multiplier is 30/6 = 5. So there will be 5*2 = 10 red marbles. 5*5 = 25 blue marbles.
30+10+25 = 65 marbles total.

Jennifer is saving money to buy a bike. The bike costs $282. She has $128 saved, and each week she adds
$14 to her savings.
How long will it take her to save enough money to buy the bike?
Answer:
11 weeks
Step-by-step explanation:
$282 = $128 + 14w
$282 -$128 = $14w
$154 = $14w
14 = 14
11 = w

Write an equation for the line that passes through the points (1,4) and (2, -4).
Answer:
-8
Step-by-step explanation:
We can use the formula [ y2-y1/x2-x1 ] to solve.
-4-4/2-1
-8/1
-8
Best of Luck!
First of all, Let's find the slope because we need it on the formula for finding the y-intercept.
m = y2 - y1 / x2 - x1
From the points given in the question,
x1 = 1
x2 = 2
y1 = 4
y2 = -4
Plugging in the above formula,
➝ m = -4 - 4 / 2 - 1
➝ m = -8 / 1
➝ m = -8
Now finding the y-intercept[tex]:[/tex]
➝ y = mx + b
And if we put in the values from our first point (1, 4) we get
➝ 1 = -8 (4) + b
➝ 1 = -32 + b
➝ b = 1 + 32
➝ b = 33
Required equation of the line:
➝ y = -8x + 33

A. Definition of Angle Bisector
B. Segment Addition Property
C. Definition of Congruent Angles
D. Transitive Property
Answer:
The following property: If a = b and b = c, then a = c. One of the equivalence properties of equality. Note: This is a property of equality and inequalities.
Congruent Angles have the same angle (in degrees or radians). That is all. These angles are congruent. They don't have to point in the same direction. They don't have to be on similar sized lines.
The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC.Jan 4, 2016
The (interior) bisector of an angle, also called the internal angle bisector (Kimberling 1998, pp. 11-12), is the line or line segment that divides the angle into two equal parts. The angle bisectors meet at the incenter.

Bobby charges $10. per lawn he mows, and an additional $5. per hour.
a) Find the independent and the dependent variables.
b) Write a linear function that models the wage of Bobby per lawn.
c) If Bobby work for 3.5 hours on a lawn, how much does he earn?
Answer:
a) independent = hours
dependent = wages
b ) W = 10 + 5h
c)27.50
Step-by-step explanation:
The independent variable is the one that you change which is the number of hours that it takes
The dependent variable is the variable that changes based on the independent variable. The wages depends on the hour worked so the wages are the independent variable
The wages equal the fixed cost plus the hourly rate times the number of hours where W is the wages and h is the number of hours
W = 10 + 5h
W = 10 + 5( 3.5)
= 10 + 17.5
= 27.5
Rosa has a chicken farm. The ratio of red to black chickens is 2 to 3. If she has a total of 20 chickens, how many are red?
Answer: If 2 out of every 3 chickens are red, then about 13 chickens would be red. There is no whole-number answer because 20/3 cannot be simplified to a whole number.

SITUACIÓN 2: Confecciones
Margarita tiene un taller de confecciones y está elaborando mascarillas de tela. Esta semana sus pedidos de mascarillas han disminuido a la mitad por lo que deberá comprar 50 % menos de tela para confeccionar mascarillas. ¿Cuál de las siguientes representaciones muestra de mejor manera las cantidades de tela que necesitará Margarita cada semana? Argumenta tu respuesta.
Answer:
La representación que muestra de mejor manera las cantidades de tela que necesitará Margarita cada semana es:
Representación A.Step-by-step explanation:
Como puedes identificar del enunciado, es ÉSTA semana en la cual los pedidos de mascarillas han disminuído a la mitad (o 50%, que sería lo mismo), por lo tanto, es en esta semana cuando el pedido de tela va a disminuir a la mitad, además debes identificar que el enunciado hace énfasis en que sus pedidos han disminuído, por lo cual puedes deducir que regularmente sus pedidos de mascarillas son el doble de lo solicitado en esta semanal, considerándose lo ocurrido en ésta semana como una anomalía, teniendo en cuenta esto, la próxima semana seguramente los pedidos volverán a la normalidad, necesitándose el doble de tela que en esta semana.
En la representación A puedes ver que se representa la cantidad de tela de ésta semana con un rectángulo, lo cual podría considerarse una unidad, y ya que sabemos que la próxima semana las confecciones de mascarillas seguramente regresarán a la normalidad, es lógico que la cantidad de tela requerida será el doble, así pues, si en esta semana se requirió una unidad de tela, en la proxima semana se requerirán dos, por lo cual la única opción que cumple con estos parámetros es la A.
evaluate f(3) for the function f(x)= 15x^2 -x+20
Answer:
[tex] \huge \boxed{f(15) = 152 }[/tex]
Step-by-step explanation:
[tex]f(x) = 15 {x}^{2} - x + 20[/tex]
To find f(3) , substitute the value of x that's 3 into f(x). That is for every x in f(x) replace it with 3.
We have
[tex]f(15) = 15( {3})^{2} - 3 + 20 \\ \: \: = 15(9) + 17 \\ = 135 + 17 \: \\ = 152 \: \: \: \: \: \: \: \: \: \: [/tex]
We have the final answer as
[tex]f(15) = 152 [/tex]

Jessie loves to go hiking on rustic trails through trees and along rivers.One day in 20 minutes of hiking, she hiked 1 mile. If Jessie hiked at a constant rate, what would that rate be?Write Jessie's hiking rate in all the ways you can think of from the information given. *
Answer:
Jessie hiked at a constant rate of 3 miles/hour
Step-by-step explanation:
Constant rate can also be called speed
The formula for constant rate /Speed = Distance (miles)/ time in hours
Distance = 1 mile
Time = 20 minutes
Converting to hours
60 minutes = 1 hour
20 minutes =
20/60
= 0.3333333333hour
Constant rate = 1mile/0.3333333333 hour
= 3.0000000003
= 3 miles/hour
You have $125.60 in quarters and
dimes. There is 956 coins
altogether. How many quarters do
you have?
Answer:
Quarters = q = 200
Dimes = d = 756
Step-by-step explanation:
Let
Dimes = d
Quarter = q
Value of each Dime = 0.10
Value of each Quarter = 0.25
d + q = 956 (1)
0.1d + 0.25q = $125.60 (2)
From (1)
d = 956 - q
Substitute d = 956 - q into (2)
0.1d + 0.25q = $125.60
0.1(956 - q) + 0.25q = $125.60
95.6 - 0.1q + 0.25q = $125.60
- 0.1q + 0.25q = 125.60 - 95.6
0.15q = 30
Divide both sides by 0.15
q = 30 / 0.15
= 200
q = 200
Substitute q = 200 into (1)
d + q = 956
d + 200 = 956
d = 956 - 200
= 756
d = 756
Therefore,
Quarters = q = 200
Dimes = d = 756

A video store charges $8 to rent a video game. You must be a member to rent from the store, but
the membership fee is free. Another video store in town charges only $3 to rent a video game for a
5 day period, but membership in this store is $50 per year. Which rental plan is more economical?
Explain in detail and give examples.
Answer:
The $3 per video game with $50 membership is more economically if you rent at least 11 games or more per year
Step-by-step explanation:
there are 365 days in a year
3 x 365 = 1095
1095 + 50 = $1145 (Cost per year)
8 x 365 = $2920 (Free Membership) cost per year
If you only rent 10 video games per year, they equals the same amount
$3 x 10 (games) = $30 Then $30 + $50 (Member Fee) = $80
$8 x 10 (games) = $80 for 10 games rental
If they rent 11 games or more per year, then the $3 rental is more economical.
$3 x 11 = $33; $33 + 50 = $83
$8 x 11 = $88
Who Wants Brainliest?
Astrid is in charge of building a new fleet of ships. Each ship requires 40 tons of wood, and accommodates
300 sailors. She receives a delivery of 4 tons of wood each day. The deliveries can continue for 100 days at
most, afterwards the weather is too bad to allow them. Overall, she wants to build enough ships to
accommodate at least 2100 sailors.
How much wood does Astrid need to accommodate 2100 sailors?
Answer:
it requires 280 ton of wood
Step-by-step explanation:
one ship can accommodate 300 sailors so for 2100 sailors you need
2100/300
7 ships
and as I ship require 40 tons of wood then 7*40
280 tons
then
he can get 4 ton of wood per day
then
280/4
70 days
therefore he needs wood for 70 days to accommodate 2100 sailors
