The square root of 20 is between 4 and 5.
Whole NumbersThey are the numbers represented by positive real numbers where the fractions and decimal numbers are not included.
For solving this question, you should list the whole numbers whose your square is less than 30. Your list must present the following numbers:
0 ⇒ 0²=0
1 ⇒ 1²=1
2 ⇒ 2²=4
3 ⇒3²=9
4 ⇒ 4²=16
5 ⇒ 5²=25
Note that 6²=36, it is greater than 30,because of this it is not in the previous list.
The question asks to determine between which two whole numbers lies the square root of 20. Therefore, from the previous list, it is possible to see that the value 20 is between 16 and 25. The square root of 16 and 25 is equal to 4 and 5, respectively.
Thus, the square root of 20 is between 4 and 5. You can check this results in your calculator:[tex]\sqrt{20}=2\sqrt{5}=4.47[/tex]

I need HELP ASAP, this is about Pythagorean theorem. HELP ASAP NOWWWW!!!!1111
Answer:
30
Step-by-step explanation:
The Pythagorean Theorem is c2 (c squared) = a2 (a squared) + b2 (b squared).
The side lengths (24 and 18) can be plugged in for a and b. C is the length of the hypotenuse.
24 Squared + 18 Squared= c squared
Use a calculator to help you.
24 squared is 576
18 squared is 324
So, 576+324=c squared
Simplify
900=c squared
Now use the squre root on both sides to get rid of the c squared. (use a calculator)
30=c

The length of a rectangle is 4 cm greater than its breadth. if the perimeter of the rectangle is 32cm what is the length and width
Given :
The length of a rectangle is 4 cm greater than its breadth. The perimeter of the rectangle is 32cm.To Find :
The Length and width of the rectangle.Solution :
We know that,
[tex]\qquad{ \bold{ \pmb{2(Length + Width) = Perimeter}}}[/tex]
So,
Let's assume the length of the rectangle as x cm. Then the breadth will become (x – 4) cm.Now, Substituting the given values in the formula :
[tex] \qquad \dashrightarrow{ \sf{2[x + (x-4)] = 32}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{2(x + x-4) = 32}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{2(2x-4) = 32}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{4x-8= 32}}[/tex]
[tex]\qquad \dashrightarrow{ \sf{4x= 32 + 8}}[/tex]

Store B sells the same computer as in the Example for $1,300. Store B offers a 20% discount on the computer. The tax rate is the same.
Which store has the lower total price? How much lower?
The store which has the lower total price is B, lower by $1040.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Given;
Store B sells the same computer as in the Example for $1,300.
Store B offers a 20% discount on the computer.
Now
Store B offers a 20% discount on the computer,
CB= CA-0.2CA
CB=1300-0.2-1300
CB= 1300-260
CB=1040
Therefore, the cost by 20 percent will be $1040.

A first quadrant coordinate plane is shown. Triangles P Q R and S T U are graphed with their hypotenuses on the line passing through the origin and the points P, R, S, and U. The angles at points Q and T are right angles. The vertices of the triangles are at: P, two comma one, Q, four comma one, and R, four comma two, and S, six comma three, T, twelve comma three, and U, twelve comma six.
What is the ratio of the length of the vertical side to the length of the horizontal side of each triangle?
Enter the correct answer in the box.
Answer:
vertical : horizontal = 1 : 2
Explanation:
UT, vertical length: 3 units
ST, horizontal length: 6 units
Therefore vertical length : horizontal length = 3 : 6 = 1 : 2
Answer:
1:2
Step-by-step explanation:
Triangle PQR has a vertical side of 1 and a horizontal side of 2.
so the ratio is vertical : horizontal is 1:2
Triangle STU has a vertical side of 3 and a horizontal side of 6.
so the ratio is vertical : horizontal is 3:6
which can be reduced by dividing both sides by 3
so the ratio is vertical : horizontal is 1:2

a basket when empty weight 350g it contains 60 seeds each weigh 250mg what is the total mass of the baskets in seed in kilograms
Answer:
0.365 kg
Step-by-step explanation:
The first I did was turn the 250mg to grams so the conversion factor would be 1 milligram = 0.0001 gram.Divide the 250mg by 1000g to get 0.25g. Multiply 0.25g by 60 to get 15g.Add 15g to the weight of the empty basket, 350g. You should end up with 365g.The question asked for kilograms so divide 365g by 1000.The final answer is 0.365kg.I hope this explains it and helps :)

Step-by-step explanation:
The sale price of the shirt is around $14.40 I think
Solution:
Note that:
35.99 - (35.99 x 60/100) = Sale PriceSimplify the equation to obtain the sale price.
35.99 - (35.99 x 60/100) = Sale Price=> 35.99 - (35.99 x 6/10) = Sale Price=> 35.99 - (107.97/5) = Sale Price=> 35.990 - 21.594 = Sale Price=> $14.396 = Sale Price=> $14.40 (Rounded)The fraction equivalent to 16/18 with denominator 45 is :
