In a bag of coloured jellybeans, the ratio of yellow to orange to red is 6 : 5 : 4. If there are 60 jellybeans in the bag, how many of each colour are there?
Based on the ratio of the jellybeans and the number of jellybeans, the number of each is:
Yellow = 24 jellybeansOrange = 20 jellybeans Red = 16 jellybeansTo find the number of yellow jellybeans:
= Ratio of Yellow/ Sum of ratios x Number of jellybeans in total
= 6 / (6 + 5 + 4) x 60
= 24 yellow jellybeans
Orange jellybeans:
= 5 / 15 x 60
= 20 orange jellybeans
Red jellybeans:
= 4 / 15 x 60
= 16 red jellybeans
In conclusion, there are several colors of jellybeans.

A metal plate measuring 32cm by 12cm is cut into
small squares of side length 4cm. How many squares will
be cut?
Answer:
24
Step-by-step explanation:
First find the area of the metal plate: 32*12=384
Find the are of each small square to see how much space it takes: 4*4=16
Divide the two to see how many can fit: 24
Tell me if you have any questions!
[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]
Area of the metal plate = [tex] L \times B [/tex]
= [tex] 32cm \times 12cm \\ 384cm^{2} [/tex]
Area of small squares = [tex] a^{2} [/tex]
[tex] 4cm \times 4cm \\ =16cm^{2} [/tex]
Number of squares that can be cut =
[tex] \frac{384cm^{2} }{16 {cm}^{2} } = 24[/tex]
Hence 24 squares can be cut.
Find the equation of the line through point (10,4) and parallel to 3x+5y=8.
[tex]3x+5y=50[/tex] is the equation of the line through point (10,4) and parallel to 3x+5y=8.
How to solve equation of the line through point and parallel to a given line?We can write the equation of a line parallel to a given line if we know a point on the line and an equation of the given line. y=2x+3 . Parallel lines have the same slope. The slope of the line with equation y=2x+3 is 2 .
Given
Equation of the line is 3x + 5y = 8.
Point = (10, 4)
First we find the slope of the line 3x + 5y = 8 by replacing it into slope intercept form:
[tex]3x + 5y = 8[/tex]
⇒ [tex]5y = -3x + 8[/tex]
⇒ [tex]y = \frac{-3}{5} x + \frac{8}{5}[/tex]
Therefore, the slope of the line is m = [tex]\frac{-3}{5}[/tex].
Now since the equation of the line with slope m passing through a point [tex](y-y_{1} )=m(x-x_{1})[/tex]
⇒ [tex]y - 4=\frac{-3}{5} (x-10)[/tex]
⇒ [tex]5(y-4)=-3(x-10)[/tex]
⇒ [tex]5y-20=-3x+30[/tex]
⇒ [tex]3x+5y=30+20[/tex]
⇒ [tex]3x+5y=50[/tex]
Hence, [tex]3x+5y=50[/tex] is the equation of the line through point (10,4) and parallel to 3x+5y=8.

10. Han is solving an equation. He took steps that are acceptable but ended up with
equations that are clearly not true.
5x + 6 = 7x + 5 - 2x original equation
5x + 6 = 7x - 2x + 5 apply the commutative property
5x + 6 = 5x+5
combine like terms
6 = 5
subtract 5x from each side
What can Han conclude as
result of these acceptable steps?
A. There's no value of x that can make the equation 5x + 6 = 7x + 5 – 2x true.
B. Any value of x can make the equation 5x + 6 = 7x + 5 - 2x true.
C. x = 6 is a solution to the equation 5x + 6 = 7x + 5 – 2x.
D. x = 5 is a solution to the equation 5x + 6 = 7x + 5 – 2x.
Answer:
There's no value of x that can make the
equation 5x + 6 = 7x + 5 – 2x true.
Hence, option 'A' is true.
Step-by-step explanation:
5x + 6 = 7x + 5 - 2x
5x + 6 = 7x - 2x + 5
5x + 6 = 5x+5
substract 5x from each side
5x-5x+6=5x+5-5x
6 = 5
This conclude that the sides of the equation are not equal.
i.e. L.H.S ≠ R.H.S
We know that when L.H.S ≠ R.H.S, then there is no solution of that equation as no x value can satisfy the equation.
Therefore, there's no value of x that can make the equation 5x + 6 = 7x + 5 – 2x true.
Hence, option 'A' is true.

A parallelogram is dilated by a scale factor of 1/4 to produce a new parallelogram. Which of the following best describes the relationship of the area of the new parallelogram to the area of the original parallelogram?
The area of the new parallelogram is 1/2 the area of the original parallelogram.
The area of the new parallelogram is 1/4 the area of the original parallelogram.
The area of the new parallelogram is 1/16 the area of the original parallelogram.
The area of the new parallelogram is 1/8 the area of the original parallelogram.
Answer: The answer is 1/6.
Step-by-step explanation:
1/4 ^2 = 0.0625 which = 1/16.
The area of the new parallelogram is 1/16 the area of the original parallelogram statement best describes the relationship of the area of the new parallelogram to the area of the original parallelogram.
When a shape is dilated by a scale factor of "k," the area of the new shape is equal to the original area multiplied by the square of the scale factor.
The given scale factor is 1/4.
Therefore, the area of the new parallelogram would be (1/4)² = 1/16 of the area of the original parallelogram.

Angles in a Triangle
There are two basic relations of angles we need to recall:
Supplementary angles add up to 180°Internal angles of a triangle add up to 180°Note a, b, and c are the internal angles of the triangle. The angle c is what is needed to a+b to complete 180°, thus:
c = 180 - ( a + b )
Also, note c and d are supplementary angles. Again, c is what is needed to d to complete 180°, thus
c = 180 - d
From the two relations above, it follows that:
a + b = d

Rectangle JKLM undergoes a sequence of transformations, resulting in rectangle J’K’L’M’. The length of side K’L’ is 6 units. The coordinates of vertex K’ are (-3, 2), and the coordinates of vertex M’ are (3, -2). Describe a sequence of transformations to rectangle JKLM that would result in rectangle J’K’L’M’.
Answer:
J,F,K
Step-by-step explanation:
J,F,K
A sequence of transformations to rectangle JKLM that will result in rectangle J'K'L'M' is a translation by 3 units and -4 units, a reflection about the y-axis, and a rotation of 90 degrees counterclockwise about the origin.
What is a rectangle?A rectangle is a quadrilateral with four right angles and four sides of equal length. It is one of the most common shapes in nature and is found in everything from architecture to floor patterns.
Now, In order to transform rectangle JKLM into J'K'L'M', a series of transformations must be applied.
The first transformation is a translation of the rectangle along the x-axis by 3 units and along the y-axis by -4 units.
This will move the original rectangle from its original position, JKLM, to the new position, J'K'L'M'.
Next, a reflection about the y-axis needs to be applied, which will flip the rectangle around the y-axis.
This will result in the length of side K'L' being 6 units.
Finally, a rotation about the origin needs to be applied. The rotation should be 90 degrees counterclockwise in order for the coordinates of vertex K' to be (-3,2) and the coordinates of vertex M' to be (3,-2).
Therefore, a sequence of transformations to rectangle JKLM that will result in rectangle J'K'L'M' is a translation by 3 units and -4 units, a reflection about the y-axis, and a rotation of 90 degrees counterclockwise about the origin.
