a) Find the length of a side of the square.
b) Show that the area of the square is 200cm²
I'll mark you as brainliest
[tex]\bold{\huge{\underline{ Solutions }}}[/tex]
Given :-The length of a diagonal is 20 cmTo Find and prove :We have to find the length of a side of the square We also have to show that the area of square is 200 cm²Solution ( a)We have,
The length of the diagonal of a square is 20 cmWe know that,
[tex]\bold{\red{ d = }}{\bold{\red{\sqrt{2}}}}{\bold{\red{ a }}}[/tex]
Where, a is the length of the side of the square d is the the length of the diagonalSubsitute the required values in the above formula :-
[tex]\sf{ 20 = }{\sf{\sqrt{2}}}{\sf{ a }}[/tex]
Squaring on both the sides :-
[tex]\sf{ 400 = 2a^{2}}[/tex]
[tex]\sf{\dfrac{400}{2}}{\sf{ = a^{2}}}[/tex]
[tex]\sf{ 200 = a^{2}}[/tex]

Hence, The side of the square is 14.14 cm
Solution ( b) :-Here, we have to prove that,
The area of square is 200 cm²We know that,
Area of square
[tex]\bold{\pink{ = side}}{\bold{\pink{\times{ side}}}}[/tex]
The side of the square is 14.14 cmSubsitute the required values,

if x-3 is a factor of 2x^k - 3 x^(k-1) +4x -39 find the value of k.
Simplify -3(9+2z).Simplify this expression and I will give you virtual points.
Answer:
-27 -6z
Step-by-step explanation:
"Simplify" in this context means "eliminate parentheses." You do that by making use of the distributive property. The factor -3 outside the parentheses multiplies each term inside parentheses.
-3(9 +2z)
= -3(9) +(-3)(2z)
= -27 -6z
Hey there!
-3(9 + 2z)
= -3(9) - 3(2z)
= -27 - 6z
= -6z - 27
Therefore, your answer is: -6z - 27

The Rose garden is formed by joining the rectangle in the semicirculation below the rectangle is 22 ft long and 18 ft wide if the gardener wants to build a fence around the garden how many feet of fences required
First, let's find the area of the rectangle.We know that the area of a rectangle is the length times width, or 20⋅32in this example:20⋅32=640So the area of the rectangle is 640ft2.You may not know the area of a semicircle, but that's fine −we know the area of a circle, or πr2.Since the area of a semicircle is half the area of a circle, we just do the area of the circle divided by 2:So the area of a semicircle is πr22.The question asks for πto just be 3.14, so instead the equation is A=3.14r22The picture gives the diameter of the circle.To find the radius, or r, we divide the diameter by 2:202=10Now we can solve for the area of the semicircle:3.14(10)223.14(100)23142157ft2Now that we now the areas of the rectangle and semicircle, we can add them up to find the area of the rose garden:640+157=797ft2

if f(x) = ax + b where a and b are Costants f(1) = 6and f(-2)=3, find the value of a and b?
Answer:
a = 1
b = 5
⇒ f(x) = x + 5
Step-by-step explanation:
Given
f(x) = ax + bf(1) = 6f(-2) = 3Therefore,
f(1) = 6 ⇒ a + b = 6
f(-2) = 3 ⇒ -2a + b = 3
Rewrite a + b = 6 to make a the subject, substitute into -2a + b = 3 and solve for b:
a = 6 - b
⇒ -2(6 - b) + b = 3
⇒ -12 + 2b + b = 3
⇒ -12 + 3b = 3
⇒ 3b = 15
⇒ b = 5
Substitute found value for b into a + b = 6 and solve for a:
⇒ a + 5 = 6
⇒ a = 1
Therefore, f(x) = x + 5

We have that the population standard deviation and confidence interval is mathematically given as

Standard deviation and the new widtha) Generally, normal distribution 95% of the values lies within 2 standard deviations from the mean.
Therefore, we have here:

SD=1
Hence, the standard deviation is
SD=1

find the coordinates if the midpoint of the line segment whose endpoints have the given coordinates (2,4) and (6 ,8)
Answer:
[tex]m = \frac{y2 - y1}{x2 - x1} \\ \frac{8 - 4}{6 - 2} \\ = \frac{4}{4} \\ m = 1[/tex]
Answer:
if you mean find the coordinates "of" the midpoint then the solution is
Step-by-step explanation:
(x1+x2)/2 and (y1+y2)/2
so
(2+6)/2=8/2=4 and (4+8)/2=12/2=6
so the coordinates of the midpoint of the given segment is
(4,6)
The perimeter of a rectangle is 52 cm. If its width is 2 cm more than one-third of its length, find the dimensions of rectangle.
(A) 12 cm x 4 cm (B) 18 cm x 8 cm (C) 15 cm x 9 cm
Answer:
(B) 18 cm x 8 cm
Step-by-step explanation:
let the length be x,
then the width is [tex]\frac{1}{3}[/tex]x + 2
2( [tex]\frac{1}{3}[/tex]x + 2 + x ) = 52
[tex]\frac{1}{3}[/tex]x + 2 + x = 26
[tex]\frac{4}{3} x[/tex] = 24
x = (24*3)/4
x = 18
then the length is 18 cm
and width is (1/3)*18 + 2 = 8
Therefore the dimensions are length:width = 18 cm : 8 cm
Answer:
(B) 18cm x 8cm
Step-by-step explanation:
Perimeter of a rectangle = 52 cm
2(length + width) = 52 ==> l + w = 26
Let x be the length
width = (x/3) + 2
x + (x/3) + 2 = 26
[(3x + x)/3] + 2 = 26
4x / 3 = 24
4x = 24 (3)
x = 6(3) ==> 18 cm
Width = (18/3) + 2
= 6 + 2 = 8 cm
So, the required dimension is 18 cm x 8 cm.

Answer:
4 and 7/8 (or as a decimal: 4.875)
Step-by-step explanation:
(Important:) Okay, so before we solve this problem we need to know the "dividing fraction rules." When you are dividing fractions, you need to remember that the second fraction is flipped and the sign goes from being a division symbol to being a multiplication symbol. It may sound confusing, but I'll explain as we go on.
First, let's turn that 1 and 5/8 into an improper fraction so that this is easier to solve. Multiply the denominator by the whole number, then add the numerator. Keep the same denominator (8 in 1 and 5/8), but place your new numerator on top instead.
1 and 5/8 = 13/8.
Now we can go through the steps of the dividing process. Flip the second fraction in the equation. Doing this changes the symbol to a multiplication symbol.
13 x 3
8 x 1
Now multiply across.
13 x 3 = 39
8 x 1 = 8
This question does not ask for an improper fraction, so let's reduce this fraction down to a mixed number and decimal.
Mixed number: 39/8 = 4 and 7/8.
Decimal: 4.875.
I hope that this helps.
Education researchers are interested in the workload expectations of freshmen at a local university. Which of the
following techniques would give a stratified random sample?
Randomly select 10 freshmen from each of the majors at the university
Randomly select 10 freshmen from the cafeteria on each of the 5 days of the first school week.
Randomly select 1 professor at the university and have them survey all of their freshman students.
Survey the students in some randomly selected freshman seminar classes, since freshmen are randomly put into
those classes
Answer:
A: Randomly select 10 freshmen from each of the majors at the university.
Step-by-step explanation:
This is because stratified random sampling is taking a population and dividing them into subpopulations. So, majors would be the best way to divide up college freshmen into different subsections to survey them about their workloads because each major would have a different answer and result.
The techniques to give a stratified random sample would be A: Randomly select 10 freshmen from each of the majors at the university.
What is simple random sampling?If the sampling is done from the population randomly, without any other rule, then such sampling is called simple random sampling. Items are selected in a fixed size, all randomly.
The best sampling is simple random sampling, as it is randomly picking data values from the population.
Stratified random sampling it is taking a population and dividing them into subpopulations.
The majors would be the best way to divide up college freshmen into different subsections to survey them about their workloads because each major would have a different result.
