Answer:
The 5 students receive the larger amount.
100:5= 20 gram per student
100÷20= 5 gram per student
Step-by-step explanation:
prove me wrong
a shorter solution that probably will get full pts :
Because each group has the same mass of the chocolate bar, whichever group has less students will get a larger amount of chocolate per student (as there are less people receiving)
and here's if you think it is kinda not too detailed :
The first group has each student receiving 100 : 5 = 20 grams of chocolate per student
The second group has each student receiving 100 : 20 = 5 grams of chocolate per student
Both solutions give us a conclusion of : The group with 5 students have each of the receiving a larger amount of chocolate.
Hooke's Law for an elastic spring states that the distance a spring stretches varies directly as the force applied. If a force of 180 newtons stretches a spring 5 cm, how much will a force of 270 newtons stretch the same spring?
7.5cm distance a spring when a force of 270 newtons stretch the same spring.
What is force?A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Given Data
A force of 180 newtons stretches a spring 5 cm
If we consider F to be the force and x to be the extension, then:
F = kx
F = 180
x = 5
Equating
180 = 5k
k = 36
F = 36x
Force of 270:
270 = 36x
x= 7.5
7.5cm distance a spring when a force of 270 newtons stretch the same spring.

|-4/3x-5|>19
Solve with work please. ;)
The inequality expression given as |-4/3x - 5| > 19 has a solution of 10.5 < x < -18
How to solve the inequality?From the question, the inequality is given as
|-4/3x-5|>19
Rewrite properly as
|-4/3x - 5| > 19
Remove the absolute bracket
So, we have the following representation
-19 > -4/3x - 5 > 19
Add 5 to all sides of the inequality
So, we have
-14 > -4/3x > 24
Multiply through by -3/4
So, we have
10.5 < x < -18
Hence, the solution to the expression is 10.5 < x < -18

Total budget of Amanda = $100.
Price of washing = $8 per dress.
Price of ironing = $5 per dress.
Total number of dress to be washed = 7.
Let x be the number of dress to be send for ironing.
The inequality becomes.

What ratio is equivalent to 7:6
Answer: 14 : 12
Step-by-step explanation:
Answer: 14:12
Step-by-step explanation: To find the ratio, you would either multiply or divide the two numbers by the same number, and you would get a simplified ratio or an equivalent one. Because 7:6 is simplified, we have to find an equivalent ratio, meaning we multiply. If we multiply 7 by two, we get 14. Multiply 6 by two to get 12. So, the answer is 14:12. Divide both 14 and 12 by two to get back to 7:6.
An airplane travels 130,000 feet horizontally drring take-off, reaching a height of 35,000 feet. the airplane travels at a constant rate.what is the plane's launch angel? round your answer to the neatest degree.
The launching angle of the plane which has reached a height of 35000 ft is 15°
Let the distance travelled by the airplane horizontally be AB
The height reached by the airplane be BC
Thus AB = 130000 ft
BC = 35000 ft
The launching angle of the airplane can be found using the formula
tanθ = opposite / adjacent
(or)
tanθ = BC / AB
Let us substitute the known values in the above equation, we get
tanθ = 35000/130000
tanθ = 0.2692
θ = tan⁻¹ (0.2692)
θ = 15.067°
θ ≅ 15°
Therefore , the launching angle of the airplane is 15°

solve for x 7 x + 6 / 4 = 2 x − 3 / 5 Give your answer as an improper fraction in its simplest form.
x = -14/9 is the solution to the equation ( 7x + 6 )/4 = ( 2x − 3 )/5 in a simplified improper fraction form.
What is the value of x in the given equation?Given the data in the question;
( 7x + 6 )/4 = ( 2x − 3 )/5x = ?To solve for x, first we cross multiply
( 7x + 6 )/4 = ( 2x − 3 )/5
5( 7x + 6 ) = 4( 2x − 3 )
Remove the parenthesis using distributive property
7x×5 + 6×5 = 2x×4 − 3×4
35x + 30 = 8x - 12
Collect like terms by moving all terms containing x to the left and all constant terms to the right side of the equation.
35x - 8x = -12 - 30
27x = -12 - 30
27x = -42
Divide both sides by 27
27x/27 = -42/27
x = -42/27
x = -14/9
Therefore, the value of x in the given equation ( 7x + 6 )/4 = ( 2x − 3 )/5 is -14/9.

The value of t for the angles of the given triangle will be 30.67.
What are the angles of triangle?The straight angle is equal to the total of the angles of a triangle. Three angles, one at each vertex and bounded by two neighbouring sides, make up a triangle. For a very long period, it was unknown if there were any alternative geometries for which the total is different.
The triangle has three sides and is a two-dimensional figure having the sum of the angles of 180 degrees.
In the given image the three angles are 2t, t + 8, and t - 12. The value of t will be calculated as:-
2t + t + 8 + t - 12 = 180
4t - 4 = 180
4t = 184
t = 184 / 4
t = 30.67

justina needs to dilate traiangle ABC using a scale factor of 1.5
Using the rule for a dilation, it is found that:
1. The table with the coordinates is given by the first image.
2. The graph of the dilated triangle is given by the second image.
3. The rule is: (x,y) -> (1.5x, 1.5y).
What is the effect of a dilation of a figure?When a figure is dilated by an scale factor of a, each vertex of the figure is multiplied by the scale factor of a, hence the rule is given by the following vector:
(x,y) -> (ax, ay).
The coordinates of the vertices of the pre-image are given as follows:
A(-2, -2), B(2,2), C(4, -2).
The dilation has a scale factor of 1.5, hence the rule for the calculation of each vertex of the image, considering the pre-image, is given as follows:
(x,y) -> (1.5x, 1.5y).
Then the vertices of the image will be given as follows:
A'(-3, -3), B'(3,3), C'(6, -3).
Each coordinate of A, B and C was simply multiplied by 1/2, and the triangle with these vertices is given by the second image at the end of the answer.

What value of c in the equation cx+4y=12 would give the equation a slope of 8?
Please provide all work and steps you used to find your answer, or the answer is pretty much useless. Thank you!
The value of c in the equation cx+4y=12 would give the equation a slope of 8 would be 32.
What is the slope of a straight line?A straight line of the form y = MX + c has its slope as 'm'
It is constant for a line. The more the slope is, the steeper the line is.
Sign convention takes bottom left to top right going line as positive sloped. And that line which goes from bottom right to top left is taken to have a negative slope. The horizontal line has 0 slopes and the vertical line has an infinite slope, as it is now at maximum steepness.
We have been given the equation cx+4y=12 which has a slope of 8.
Also cx+4y=12
4y = 12 - cx
y = 12/4 - cx/4
y = 3 - cx/4
Then we know that straight line of the form y = mx + c
By comparing the formula;
y = 3 - cx/4
Slope = c/4 = 8
c/4 = 8
c = 8(4)
c = 32
Therefore, the value of c in the equation cx+4y=12 would give the equation a slope of 8 would be 32.

What is an equation of the line that passes through the point (6,1)(6,1) and is parallel to the line x+3y=15
Answer:
Step-by-step explanation:
Let's write everything in slope-intercept format of y=mx+b, where m is the slope and b is the y-intercept.
x+3y=15
3y= -x + 15
y = (-1/3)x + 5
Parallel lines will have the sam slope, in this case -(1/3), So the new line will be:
y = (-1/3)x + b
We need to fijnd a value of b that will force the ine through point (6,1). Enter (6,1) in the equation and solve for b:
y = (-1/3)x + b
1 = (-1/3)(6) + b
1 = (-2) + b
b = 3
The parallel line is:
y = (-1/3)x + 3
