Jake is making bracelets to give to his sisters. He uses 4 rainbow charms and 8 white star charms for his younger sister's bracelet. He makes his older sister's bracelet a little bigger, so he uses 5 rainbow charms and 10 white star charms. Does Jake use the same ratio of rainbow charms to white star charms in both bracelets?
Answer: Yes.
Step-by-step explanation: 4:8 simplifies to 1:2, since he used half as many rainbow charms as he did white stars. 5:10 also simplifies to 1:2. If they both have half as many rainbow charms as white, then both of his sister’s bracelets keep the same ratio.

Which of the following is equivalent to (6y + 4x) + 7x?
6y + 11x
6y + 28x
7x(6y + 4x)
24xy + 7y
Answer:
6y + 11x
Step-by-step explanation:
Let's simplify step-by-step.
6y+4x+7x
Combine Like Terms:
=6y+4x+7x
=(4x+7x)+(6y)
=11x+6y
Answer:The answer would be the first one 6y + 11x
Step-by-step explanation:All you would have to do is do 4x + 7x which would equal 11x. So the answer would be 6y +11x

a weight is attached to the end of a spring. its height after ttt seconds is given by the equation \qquad h(t)
The weight, according to the supplied statement, reaches its greatest height at 4.25 seconds.
When is the maximum height?This time is determined by the projectile's starting velocity as well as the angle of projection. When the projectile reaches a vertical velocity equal zero magnitudes, it has reached its maximum height. Furthermore, gravity would take over and accelerate the thing downward.
According to the given data:Given that,
y = -2sin[tex](\frac{2\pi (t+1)}{7})[/tex] + 5
For maximum height,
sin(2π(t + 1))/7) = -1
(2π(t + 1))/7) = sin⁻¹ (- 1)
(2π(t + 1))/7) = sin⁻¹ (- 1)
(2π(t + 1))/7) = 3π/2
t + 1 = 21/4
t = 4.25 seconds
Hence,
we can conclude that at t = 4.25 seconds,
The weight, according to the supplied statement, reaches its greatest height at 4.25 seconds.

Step-by-step explanation:
Find 62÷2. Use the distributive property.
Answer: The distributive property tells us how to solve expressions in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. ... Then we need to remember to multiply first, before doing the addition!
Step-by-step explanation: According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Answer: 31
First, we can break down the number 62.
We will break the number 62 down into 60 + 2.
Now, we will divide the numbers we get after we break down 60.
60 ÷ 2 = 30
2 ÷ 2 = 1
30 + 1 = 31
The answer to your question is 31.

La Sra.Elena y el Sr.Eulalio,abortan taxis diferentes de la misma empresa el costo del servicio es un importe fijo de salida (banderazo) mas otra cantidad por los kilometros recorridos.Si la SraElena paga $190 por recorrer 8 km y el Sr Eulalio paga $130 por correr 5 km calcular el costo de banderazo y el costo por kilometro recorrido
Answer:
$ 30
$ 20
Step-by-step explanation:
Sea el costo fijo xy el costo por km sea y suponiendo que es el mismo para ambos taxis.
De la pregunta obtenemos las dos ecuaciones
[tex]x+8y=190\quad ...(i)[/tex]
[tex]x+5y=130\quad ...(ii)[/tex]
Aplicando [tex](i)-(ii)[/tex]
[tex]8y-5y=190-130\\\Rightarrow 3y=60\\\Rightarrow y=\dfrac{60}{3}\\\Rightarrow y=20[/tex]
Sustituyendo en [tex](ii)[/tex]
[tex]x+5y=130\\\Rightarrow x+5\times 20=130\\\Rightarrow x=130-100\\\Rightarrow x=30[/tex]
Entonces, el costo fijo es de $ 30 y el costo por km es de $ 20.
Consider the division expression 7 1/2 divided by 2. Select all multiplication equations that correspond to this division expression. 2 * ? = 7 1/2 7 1/2 * ? = 2 2 * 7 1/2 = ? ? * 7 1/2 = 2 ? * 2 = 7 1/2 I need help with this question!!! Which one is the answer!!!
Answer:
2 * ? = [tex]7\frac{1}{2}[/tex]
OR
? * 2 = [tex]7\frac{1}{2}[/tex]
Step-by-step explanation:
The given expression is:
[tex]7\frac{1}{2}[/tex] divided by 2.
The given expression a mixed fraction.
Let the result of the expression be equal to [tex]x[/tex].
Therefore, the expression can be written as:
[tex]7\frac{1}{2} \div 2 = x[/tex] ...... (1)
Multiplying equation (1) by 2:
[tex]7\frac{1}{2} = 2 \times x[/tex]
OR
[tex]7\frac{1}{2} = x \times 2[/tex]
Alternatively, this expression can be written as:
2 * ? = [tex]7\frac{1}{2}[/tex]
OR
? * 2 = [tex]7\frac{1}{2}[/tex]
Therefore, the following multiplication equations corresponding to equation (1) are:
2 * ? = [tex]7\frac{1}{2}[/tex]
OR
? * 2 = [tex]7\frac{1}{2}[/tex]

What is m ZABC?
c=67 d=60
mABC = 60°
mABC = 67 °
mABC = 120°
mABC = 127°
Answer:
m∠ABC = 127°Step-by-step explanation:
From triangle BCD:
m∠BCD + m∠CDB + m∠DBC = 180°
67° + 60° + m∠DBC = 180°
m∠DBC = 180° - 127°
An angle ABD is straight angle, so:
m∠ABC + m∠DBC = 180°
m∠ABC + 180° - 127° = 180°
m∠ABC = 127°

Both the race cars will hit the ground at the same time.
The concept used here is free fall formula which can be defined as . Free fall means that an object is falling freely without a forces acting upon it except gravity, a described constant, g = -9.8 m/s2. The distance the object falls, or height, h, is 1\/2 gravity x the square of the time falling. Velocity is described as gravity x time.
Here the two cars are free falling in the vertical direction and the initial velocity in the vertical direction is zero. So the landing time of both the cars is only related to the height and the acceleration of gravity.
Hence, the cars are falling from the same height, h and g are the same so they take same time to touch the ground.

The populations of Cities A and B are 3.7 x 105 and 2,115,000, respectively. The population of City C
is twice the population of City B. The population of City C is how many times the population of City A?
Answer:
a = 370,000
b = 2,115,000
c = 4,230,000
city c is 11.4 times the population of city a
Step-by-step explanation:
10 to the 5 degree is 100,000. multiply that by 3.7 to get the population of City a.
City C is 2,115,000 * 2.
divide the population of City C by the population of City a.
4,230,000 ÷ 370,000= 11.43
The cost, Y (in dollars) to provide for guests at a dinner party is proportional to the number x of guests attending the party. It costs 30 dollars to provide food for 4 guests.
Maybe you missed to add the complete question. After a little research I was able to find the complete question which is as follows:
''The cost y(in dollars) to provide food for guests at a dinner party is proportional to the number x of guests attending the party. It costs $30 to provide food for 4 guests. a. Write an equation that represents the situation. b. Interpret the slope. c. How much does it cost to provide food for 10 guests?''
So, I am solving based on this complete question.
Answer:
Please check the explanation.
Step-by-step explanation:
a. Write an equation that represents the situation.
As the cost and the number of guests are proportional.
So the equation of the form
[tex]y = mx[/tex]
Plug in the values y = 30 and x = 4 to find m
[tex]y = mx[/tex]
30 = m (4)
m = 30/4
= 7.5
Now, substituting m = 7.5 in the equation y=mx
[tex]y = mx[/tex]
[tex]y = 7.5x[/tex]
b) Interpreting Slope
Given that the units for y are dollars, and the units for x are guests.
Thus, the slope 7.5 means it costs $7.5 per guest.
c) How much does it cost to provide food for 10 guests?''
We know the equation
[tex]y = 7.5x[/tex]
put x = 10
y = 7.5(10)
y = $75
Thus, it costs 75 dollars for 10 guests.

Answer:
D. (1, 3.5)
Step-by-step explanation:
The midpoint formula is useful.
M = (E + F)/2 = ((5, -1) +(-3, 8))/2 = (5 -3, -1+8)/2 = (2, 7)/2
M = (1, 3.5)
The midpoint is (1, 3.5), matching choice D.
