The table shows the relationship between the number of drops of food color added to different number of cups of cake frosting. Look at the first picture.
Which point below shows an equivalent ratio in this situation? Look at the second picture.
A. Point B, because if cups of frosting are 50, then drops of food coloring will be 200
B. Point B, because if drops of food coloring are 50, then cups of frosting will be 200
C. Point J, because if cups of frosting are 40, then drops of food coloring will be 10
D. Point J, because if drops of food coloring are 40, then cups of frosting will be 10
Answers
This is because the proportion of frosting to food coloring is 1:4, and if the answer to A is simplified (50:200), the ratio would be the same.
Answer:
Option A. will be the answer.
Step-by-step explanation:
From the given table we will find the relation first and the we will try to find the point with the same relation in the graph.
From the given table ratio of Cups of frosting and Drops of food color is = [tex]\frac{\text{Cups of frosting}}{\text{Drops of food color}}[/tex]
= [tex]\frac{2}{8}[/tex]
= [tex]\frac{1}{4}[/tex]
Or 1 : 4
Now the point B shows the ratio between food color and frosting = [tex]\frac{\text{Cups of frosting}}{\text{Drops of food color}}[/tex]
= [tex]\frac{\text{x-coordinates}}{\text{y-coordinates}}[/tex]
= [tex]\frac{50}{200}[/tex]
= [tex]\frac{1}{4}[/tex]
The same ratio 1 : 4
Option A. will be the answer.

why is a stem and leaf plot called a stem and leaf plot?
Answers
Stem = the first digit, or digits
Leaf = the last digit
Ex: The stem of 32 would be 3 and the leaf would be 2.
A stem-and-leaf plot gets its name from the way the data is structured. The 'stem' represents the highest place value digits of the numbers in the dataset, and the 'leaf' represents the lower place value digits. These plots keep the actual numerical data intact, providing more detail than other data representations like bar graphs or histograms.
Explanation:The term stem-and-leaf plot, also known as a stemplot, originates from the way data is structured in this type of graphical representation. The 'stem' in a stem-and-leaf plot stands for the highest place value digits of the numbers in the dataset, similar to the stem of a plant that holds up the leaves. The 'leaf' stands for the lower place value digits, similar to the leaves that extend from the stem. For example, in a dataset [23, 24, 33, 35], 2 and 3 would be stems, and the various units (3, 4 for 2 and 3, 5 for 3) would be leaves.
One of the main purposes of a stem-and-leaf plot is that it keeps the actual numerical data intact, as opposed to other graphical representations like bar graphs or histograms which group data into classes, thus providing a more detailed view of the data distribution.

Select one:
a. The x-intercept is (0,-3) and the y-intercept is (6,0).
b. The x-intercept is (-3,0) and the y-intercept is (0,6).
c. The x-intercept is (4,0) and the y-intercept is (0,-2).
d. The x-intercept is (0,6) and the y-intercept is (-3,0).
Answers
-2y = -4x - 12
y = 2x + 6
The y-intercept is b, in the equation y = mx + b.
So that means here the y-intercept is 6.
Now to get the x-intercept, you need to put the y at 0.
0 = 2x + 6
-6 = 2x
-3 = x
X-intercept is -3.
Also remember that the x and y intercepts look like this: (x, y). For the x-intercept, the y has to be at 0. For the y-intercept, the x has to be at 0.
So the answer is B.
The x-intercept is (-3,0) and the y-intercept is (0,6).
The correct option is B,
What are intercepts?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
Given information:
4x - 2y = -12.
To find the x-intercept, we set y to zero and solve for x:
4x - 2y = -12
4x - 2(0) = -12
4x = -12
x = -3
So the x-intercept is (-3, 0).
To find the y-intercept, we set x to zero and solve for y:
4x - 2y = -12
4(0) - 2y = -12
-2y = -12
y = 6
So the y-intercept is (0, 6).
Therefore, the answer is b. The x-intercept is (-3,0) and the y-intercept is (0,6).

Please give brainliest
With the given translation rule, to find new coordinates of a point L in trapezoid JKLM, apply it to the original coordinates by moving right by 8 units and down by 3 units. If original coordinates of L were (2,5), new coordinates will be (10,2).
Explanation:In geometry, a translation is a type of transformation that slides a figure along a straight line. In this case, the translation rule given is (x, y) -> (x+8, y-3). This means that every point in the trapezoid is being moved 8 units to the right (increase in x-coordinate) and 3 units down (decrease in y-coordinate).
Per your question, to find the new coordinates of point L after the translation, you simply need to apply this rule to the original coordinates of point L. If for example, the original coordinates of point L were (2, 5), its new coordinates after the translation would be calculated as follows: (2+8, 5-3) = (10, 2).

A scientist measures the angle x and the distance y between the Earth and the moon. Using complete sentences, explain how the scientist can use only these two measurements to calculate the distance between the Earth and the Sun.
Answers
From the trigonometric rules:
tan(theta)=opposite/adjacent
In this case: theta=x , opposite=y and adjacent=z
tan(x)=y/z
All terms in the equation are known except for 'z'.
therefore the distance between the earth and the sun denoted by the symbol 'z' is equal to: y/tanx
tan =opposite/adjacent
In this case: tan =X , opposite=Y and adjacent= D
tan(x)=Y(opposite) /D(adjacent)
All terms in the equation are known except for 'D the distance'.
So the distance between the earth and the sun indicate by the symbol 'D' is equal to: y/tan(x)

The second type of the bread be bread B
Let the flour be 'f' and the butter be 'b'
We need 150f + 50b for bread A and 75f + 75b for bread B
We can compare the amount of flour and bread needed for each bread and write them as ratio
FLOUR
Bread A : Bread B
150 : 75
2 : 1
We have a total of 2250gr of flour, and this amount is to be divided into the ratio of 2 parts : 1 part. There is a total of 3 parts.
2250 ÷ 3 = 750 gr for one part then multiply back into the ratio to get
Bread A : Bread B = (2×750) : (1×750) = 1500 : 750
BUTTER
Bread A : Bread B = 50 : 75 = 2 : 3
The amount of butter available, 1250 gr is to be divided into 2 parts : 3 parts.
There are 5 parts in total
1250 ÷ 5 = 250 gr for one part, then multiply this back into the ratio
Bread A: Bread B = (2×250) : (3×250) = 500 : 750
Hence, for bread A we need 1500 gr of flour and 500 gr of butter, and for bread B, we need 750 gr of flour and 750 gr of butter.
The amount of Bread Type 1 is 10 pieces
The amount of Bread Type 2 is 10 pieces
Further explanationSimultaneous Linear Equations can be solved using one of the following methods :

Amount of Bread Type 2 = B
1 piece of bread type 1 requires flour as much as 150 grams and 1 piece of bread type 2 requires flour as much as 75 grams, while the total amount of flour is as much as 2250 grams, then:
[tex]150A + 75B = 2250[/tex]
[tex]2A + B = 30[/tex]
[tex]\boxed{B = 30 - 2A}[/tex] → Equation 1
1 piece of bread type 1 requires butter as much as 50 grams and 1 piece of bread type 2 requires butter as much as 75 grams, while the total amount of butter is as much as 1250 grams, then:
[tex]50A + 75B = 1250[/tex]
[tex]2A + 3B = 50[/tex]
[tex]2A + 3(30 - 2A) = 50[/tex] ← Equation 1
[tex]2A + 90 - 6A = 50[/tex]

V (t)?
V0 1000
R 0.05
T 5 years
V (5)=1,000×(1−0.05)^(5)=773.78
The predicted value of the treadmill after 5 years, with an annual depreciation rate of 5%, is approximately $773.78. This calculation uses the exponential decay formula and corresponds to option A).
To predict the value of a treadmill in 5 years that was bought new for $1000 and decreases 5% each year, we can use the formula for exponential decay:
V = [tex]P(1 - r)^t[/tex]
Where:
V is the future value of the treadmill,
P is the original value ($1000),
r is the rate of decay (5% or 0.05), and
t is the time in years (5 years).
By substituting the values we have:
V = $1000(1 - 0.05)⁵
V = $1000(0.95)⁵
V = $1000(0.77378) = $773.78
Therefore, the predicted value of the treadmill after 5 years is approximately $773.78, which corresponds to option A).

What is elimination method?The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.
According to the question
5x + 4y= 2 ------------------- (1)
3x + 3y = -3 ------------------- (2)
Now,
solving both equation by elimination method
Multiplying equation (1) by 3 and by 2 to equation (-4)
So, y can be eliminated
3(5x + 4y)=2 * 3
15x + 12y = 6 -------------- (3)
-4(3x + 3y) = -3*-4
-12x - 12y = 12 -----------------(4)
Now,
Adding both eq(3) and (4)
3x = 18
x = 6
Putting value of x in eq(1)
5*6 + 4y = 2
30 + 4y = 2
4y = 2 - 30
4y = - 28
