Answer:
y = 1/9 x z^3
Step-by-step explanation:
y is jointly proportional to x and z^3
y = k * x * z^3 where k is the constant of proportionality
y =12, x = 4 and z =3
12 = k * 4 * 3^3
12 = k * 4 * 27
12 = k * 108
12/108 = k
1/9 = k
y = 1/9 x z^3

Which shows the result of a correct substitution for the system y=2x+3 and 3x+2y=9?
Answers
Answer:
The result of the correct substitution gives:
x = 3/7 and y = 27/7
Step-by-step explanation:
From the given information:
y = 2x + 3 ---- (1)
3x + 2y = 9 ---- (2)
By using substitutional method
Substitute the value of y = 2x +3 into equation (2)
So,
3x + 2(2x + 3) = 9
3x + 4x + 6 = 9
7x = 9 - 6
7x = 3
x = 3/7
From equation (1), let replace the value of x to be 3/7
So,
y = 2x + 3
y = 2(3/7) + 3
y = 6/7 + 3
y = 27/7

Because your Christmas tree is bigger this year, you can decorate it with more ornaments! Last year, you put 35 ornaments on the tree. Since the tree is now bigger, you have room to increase the number of ornaments by 40%.
a. How many more ornaments can you put on the tree?
b. What is the total number of ornaments you are putting on the tree this year?
Answers
Answer:
You can put a total of 14 more ornaments this year.
The total number of ornaments you can put are 35+14= 49
Step-by-step explanation:
Answer:
See below :)
Step-by-step explanation:
a. This year, we know that the space increased by 40% of the last years.
Last year: 35 ornaments
This year: 35 ornaments + 40%(35) ornaments
We want to calculate 40%(35) so:
35 * 0.4 = 14
a answer. I can put 14 more ornaments on the tree.
b. In order to calculate the total ornaments, we want to add last year's + the new space
We already calculated 40%(35) is 14 so all we have to do is add 35 and 14:
35 + 14 = 49
b answer. The total number of ornaments I can put on the tree this year is 49.

Write the equation of a line in point-slope form that is parallel to the line y=2x-5 and goes through the point (-1,4)
Answers
(y-4) = 2(X+1)
Step-by-step explanation:
Hey there!
The given eqaution is; y = 2x-5.......(i)
Now; As the eqaution is in the form of y= mx+b.
Slope(m1) = 2.
As per the condition of parallel lines, slope of the 1st equation (m1) = slope of 2nd eqaution (m2).
Therefore, m1= m2= 2
Now, use one point formula for finding the eqaution of the line which passes through the point.
(y-y1) = m2(x-x1)
~ Put all values.
(y-4) = 2(X+1)
You can simply write upto here. But it you want to make it simplified form then, (look below)
~ simplify it.
y = 2x +2+4
The eqaution of the line which is parallel to y = 2x -5 and point (-1,4) is y = 2x + 6.
Hope it helps.....
Answer: y - 4 = 2(x + 1)
Step-by-step explanation:
The point slope form formula says that y - b = m(x-a) where m is the slope,b is the y coordinate of a given point , and a is the x coordinate of the same point.
Remember that parallel lines have the same slopes but different y-intercepts, meaning that m will equal to 2 because the slope for the line y=2x-5 is 2.
m will be 2, b will be 4 , and a will be -1.
y - 4 = 2(x - (-1) which reduces to
y - 4 = 2(x + 1)

The value of x in the given hexagon is 19.8°.
What is a polygon?A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.
Each line of the polygonal circuit's segments is referred to as its edges or sides.
We know the sum of interior angles in a hexagon is 720°.
∴ 135° + (5x - 4)° + (3x + 31)° + (7x - 64)° + (4x + 15)° + (6x - 8)° + 120° = 720°.
5x + 3x + 7x + 4x + 6x = (720 - 135 + 4 - 31 + 64 - 15 + 8 - 120)°.
25x = 495°.
x = 19.8°.

You are mixing together the contents of Container A and Container B to produce 40 gallons of 9% solution. How many gallons from each container are needed to create the 40 gallons of 9% cleaning solution? Write your answers as integers only.
Container A: 20% Cleaning Solution =
gallons
Container B: Pure Water =
gallons
Answers
Answer:
Amount of chemical solution = 18 gallon
Amount of pure water = 22 gallon
Step-by-step explanation:
Assume;
20% of solution = x
So,
Amount of pure water = 40 gallons - x
Amount of pure water = 40 - x
Computation:
20% of x = 9% of 40 gallon
0.2 x = 3.6
x = 3.6 / 0.2
x = 18 gallon
So,
Amount of chemical solution = 18 gallon
Amount of pure water = Total solution - Amount of chemical solution
Amount of pure water = 40 -18
Amount of pure water = 22 gallon

Answer:
Angle 1 is 140.
Step-by-step explanation:
Set angle 1 and angle 3 equal to each other since they are congruent to each other to get this equation 20x+60=30x+20. Subtract 20x on both sides to get this equation 60 = 10x + 20. Subtract 20 on both sides to get to 40 = 10x. Divide 10 on both sides to get your x-variable which is 4. Since you are solving for angle 1, plug in the x-value to get 20(4)+60. You should get 140 degrees as your final answer.

Calculate the speed of a wave with a frequency of 2 Hz, amplitude of 3m, and a wavelength of 10m
Answers
10 * 2 = 20
The speed is 20 m/s
The speed of a wave is the product of the wavelength and its frequency.
The speed of the wave is 20m/s
Given
[tex]\lambda = 10m[/tex] --- the wave length
[tex]f =2Hz[/tex] --- the frequency
[tex]A = 3m[/tex] --- the amplitude
The speed of wave (v) is calculated as follows:
[tex]v =f\lambda[/tex]
Substitute values for f and [tex]\ambda[/tex][tex]\lambda[/tex]
[tex]v = 2Hz \times 10m[/tex]
[tex]v = 20ms^{-1}[/tex]
