1:4 is the answer to the question.
Answer:
Option B. 1 : 4.
Step-by-step explanation:
In a lab 30% acid solution and 5% acid solution were mixed to prepare 10% acid solution.
We have to calculate the ratio of both the acids should be mixed to prepare 10% acid solution.
Let the volume of 30% solution was used = x ml
and the volume of 5% acid was used = y ml
Therefore the equation will form as
30%.x + 5%.y = 10%.(x + y)
0.30x + 0.05y = 0.10(x + y)
Now we transfer the similar terms in one side of the equation.
0.30x - 0.10x = 0.10y - 0.05y
0.20x = .05y
[tex]\frac{x}{y}= \frac{.05}{0.20}[/tex]
x : y :: 1 : 4
Therefore solutions will be mixed in a ratio of 1 : 4
Option B. 1 : 4 is the right answer.

A park district has 25 elm trees and 20 oak trees to be planted.They are separating the trees for different areas.They want each area to have the same number of elm trees and the same number of oak trees. What is the greatest number of areas that can be created?
Answer: There are 5 number of areas that can be created.
Step-by-step explanation:
Since we have given that
Number of elm trees = 25
Number of oak trees = 20
According to question, They want each area to have the same number of elm trees and the same number of oak trees.
So, the greatest number of areas that can be created is H.C.F. of 25 and 20 = 5.
Hence, there are 5 number of areas that can be created.
The graph shows the cost of purchasing T-shirts. Find the constant rate of change for the graph. Then explain what points (0,0) and (1,9) represent
Answer:
Constant rate of change is 9
Step-by-step explanation:
To find the constant rage of change we pick 2 points from the graph
points (0,0) and (1,9)
Rate of change is the slope
[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]slope =\frac{9-0}{1-0}=9[/tex]
Slope = 9/1
Constant rate of change is 9
points (0,0) and (1,9) represent 9 units up from (0,0) and 1 units the right

Cupcakes are packed 6 to a box. If Abby only buys full boxes of cupcakes give two possible numbers of cupcakes that she could buy.
Answer:
The two possible numbers of cupcakes that she could buy can be 6,12,18 etc.
Step-by-step explanation:
As given:
Cupcakes are packed 6 to a box.
Abby only buys full boxes of cupcakes.
So, basically if she only wants full boxes, then she must get cupcakes in multiples of 6. Like : 6,12,18,24....
Therefore, any number that is a multiple of six is acceptable here.

Name the property illustrated by the statement:
If d+1=f, then d=f-1 .
It's a property of equality, but I'm not sure which one. Please explain which one it is and why it's that one. Thanks! :-)
Answer:
subtraction property of equality.
Step-by-step explanation:
IF any number is added on both sides of equation then it is addition property of equality.
If any number is subtracted from both sides of the equation then it is subtraction property of equality.
If d+1=f, then d=f-1 .
[tex]d+1=f[/tex]
To get 'd' alone , 1 is subtract from both sides
[tex]d=f-1[/tex]
1 is subtract from both sides of the given equation.
So it subtraction property of equality.

Classify each pair of labeled angles as complementary, supplementary, or neither.
Drag and drop the choices into the boxes to correctly complete the table. Each pair of angles may belong to more than one category.
Answer:
The table in the attached figure
Step-by-step explanation:
we know that
If the sum of two angles is equal to [tex]90\°[/tex] then the angles are complementary
If the sum of two angles is equal to [tex]180\°[/tex] then the angles are supplementary
In this problem
[tex]61\°+29\°=90\°[/tex] ------> the angles are complementary
[tex]90\°+89\°= 179\°[/tex] -------> neither (not complementary, not supplementary)
[tex]63\°+47\°= 110\°[/tex] -------> neither (not complementary, not supplementary)
Answer:
61 and 29 are complementary and 90 and 89 and 63 and 47 are neither

What is the slope of the line on the graph? Enter your answer in the box. A coordinate grid that includes the line y equals negative two x. Points are plotted at begin ordered pair 3 comma negative six end ordered pair begin ordered pair 0 comma 0 end ordered pair and begin ordered pair negative 3 comma 6 end ordered pair.
Final answer:
The slope of the line described by the equation y = -2x is -2. This indicates that the line has a negative slope, decreasing 2 units on the y-axis for every increase of 1 unit on the x-axis.
Explanation:
The slope of a line is a measure of its steepness, typically represented by the symbol 'm' in the equation of a straight line, y = mx + b, where 'm' is the slope and 'b' is the y-intercept. To calculate the slope of a line given points on a graph, we use the formula slope = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two distinct points on the line. For the given line y = -2x, which is already in slope-intercept form, the slope 'm' is directly provided as -2. No calculation is needed since the equation itself indicates that the slope is -2, meaning for every increase of 1 on the x-axis, there is a decrease of 2 on the y-axis.

Which ordered pair minimizes the objective function C = 60x + 85y?. (0, 160). (55, 70). (80, 50). (170, 0)
Step-by-step explanation:
The given objective function is [tex]C = 60x + 85y[/tex]
To check that which ordered pair is minimizing the objective function-we will substitute all the ordered pair one by one in the given function and we will calculate the value of C. The ordered pair which will give the minimum value will be the answer.
For (0, 160)
[tex]C=60\times 0+85\times 160=13600[/tex]
For (55, 70)
[tex]C=60\times 55+85\times 70=9250[/tex]
For (80, 50)
[tex]C=60\times 80+85\times 50=9050[/tex]
For (80, 50)
[tex]C=60\times 170+85\times 0=10200[/tex]
Hence the ordered pair which minimizes the objective function is (80, 50)
