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.

What is coordinate geometry?Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
The pair of points that have equal X coordinates that is abscissa will be
From the diagram, the coordinate of the points R, Q, S, and T will be
R ⇒ (-5, -7)
Q ⇒ (-5, 6)
S ⇒ (5, -6)

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.

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.

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

The quotient of two consecutive positive integers is 1.02. What is the sum of these two integers?
Plz help asap I need it badly
The sum of the two consecutive positive integers, approximated to be 51 and 52, is 103.
If the quotient of two consecutive positive integers is 1.02, it indicates a very small difference between the two integers.
However, since integers cannot have fractional parts, the quotient cannot be exactly 1.02. If we assume the quotient is approximately 1.02, it means the two consecutive integers are very close to each other.
Let's solve it:
Let's denote the smaller integer as x, then the larger one would be x + 1.
So, we have:
[tex]\[\frac{x}{x + 1} \approx 1.02\][/tex]
Now, we can cross multiply:
[tex]\[x \approx 1.02(x + 1)\][/tex]
[tex]\[x \approx 1.02x + 1.02\][/tex]
Subtract 1.02x from both sides:
[tex]\[0.02x \approx 1.02\][/tex]
Now, divide both sides by 0.02:
[tex]\[x \approx \frac{1.02}{0.02}\][/tex]
[tex]\[x \approx 51\][/tex]
So, one integer is approximately 51. The next consecutive integer would then be 52.
The sum of these two integers is 51 + 52 = 103.
Thus, the sum of the two consecutive positive integers is approximately [tex]\(\boxed{103}\).[/tex]
