In a lab, a 30% acid solution is being mixed with a 5% acid solution to create a 10% acid solution. What is the ratio of the amount of the 30% solution to the amount of 5% solution used to create the 10% solution?
1:3
1:4
1:5
1:6
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.
Which is a better approximation of the square root of20, 4.5 or 4.47
Answer:
4.47
Step-by-step explanation:
Given : [tex]\sqrt{20}[/tex]
To Find : Which is a better approximation
Solution:
20 lies between two perfect squares i.e. 16 and 25
Square root of 16 = 4
Square root of 25 = 5
So, Square root of 20 must lie between 4 and 5
Using calculator
The [tex]\sqrt{20}=4.47[/tex]
Hence a better approximation of the square root of 20 is 4.47.

There were 340,000 cattle placed on feed. Write an equivalent ratio that could be used to find how many of these cattle were between 700 and 799 pounds. How many of the 340,000 cattle placed on feed were between 700 and 799 pounds?
There were 340,000 cattle placed on feed
How many of the 340,000 cattle placed on feed were between 700 and 799 pounds?
Given the fraction of total cattle for 700 - 799 pounds is 2/5
Let x be the number of cattle between 700 - 799 pounds
We make a proportion using the fraction
[tex]\frac{2}{5} = \frac{x}{340,000}[/tex]
Cross multiply it and solve for x
340000* 2 = 5x
680000 = 5x
Divide by 5 on both sides
So x= 136,000
There were 136,000 cattle between 700 and 799 pounds

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 perimeter of a rectangle is 24 feet. The length is 3 feet less than twice the width. Which of the following systems would be used to solve this problem ???
The system of equations are 24 = 2(l + w) and l = 2w - 3 option third is correct.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Let l be the length and w be the width of the rectangle
By the formula of perimeter:
24 = 2(l + w)
l = 2w - 3 (The length is 3 feet less than twice the width)
The system of equations:
24 = 2(l + w)
l = 2w - 3
Thus, the system of equations are 24 = 2(l + w) and l = 2w - 3 option third is correct.

[Statistics and Probability] How to find if something is mutually exclusive given a sample space?
To find if events A and B are mutually exclusive given a sample space, check if they can occur at the same time. If P(A AND B) = 0, they are mutually exclusive. If they share common outcomes, they are not mutually exclusive.
To determine if two events in a sample space are mutually exclusive, you need to evaluate if the two events can occur simultaneously. If two events, A and B, are mutually exclusive, this means that they cannot happen at the same time, and therefore the probability of A AND B occurring together, denoted as P(A AND B), is zero.

Answer:
the answe is 60 on usapreptest
Step-by-step explanation:
The rate at which Ebony driving is 60 miles per hour.
The given coordinate point is (3, 180).
Average rate is a measure of how much the function changed per unit, on average, over that interval.
Here, 180/3 = 60 miles per hour
Therefore, the rate at which Ebony driving is 60 miles per hour.
