Equation (A) 3¹ can be correctly placed in Jeremy's work.
What exactly are equations?An equation, in its most basic form, is a mathematical statement that shows that two formulas are equal.For example, 3x + 5 = 14 is an equation in which 3x + 5 and 14 are 2 different expressions kept separate by a 'equal' sign.So, in the situation, Jeremy concludes: [tex]\sqrt{9}=9^{\frac{1}{2}}[/tex]
Which results from the work: [tex]\sqrt{9}=3=3^1=3^{\frac{1}{2}+\frac{1}{2}}=3^1=9^{\frac{1}{2}}[/tex]The missing piece is: [tex]\frac{1}{2}+\frac{1}{2}=1[/tex]The answer is 3¹ if two halves equal a whole.Therefore, (A) 3¹ is the equation that should be correctly placed in Jeremy's work.

The amount of money that is invested in the account that yields an 8% interest is $6,050.
The amount of money that is invested in the account that yields a 4% interest is $4,650.
How much was invested in each account?Given these two equations:
x = y + 1400
x - y = 1400 equation 1
0.08x + 0.04y = 670 equation 2
take the following steps to determine the amount of money invested at each interest rate:
Multiply equation 1 by 0.08
0.08x - 0.08y = 112 equation 3
Subtract equation 3 from equation 2
0.12y = 558
Divide both sides by 0.12
y = 558 / 0.12

Based on the fact that Lila made a chart that had 8 rows and 4 columns, the number of spaces in the chart is 32 spaces.
Lila can use 8s factors or 4 factors to solve because both 8 and 4 are factors of 32.
How to find the spaces created?The number of spaces can be found by the formula:
= Number of rows x Number of columns
= 8 x 4
= 32 spaces
Factors of 8 and 4 can be used for 32 because when a number is a factor of another number, then all the factors of the first number, are also the factors of the other number.

The number0.000000675 can be written in scientific notation as 6.75 x 10x . What is the value of x?
Answer:
-7
Step-by-step explanation:
The decimal 0.000000675 can be written as 6.75 x 10^-7 in scientific notation. To write a decimal in scientific notation, you need to count how many decimal places the decimal needs to be moved in order to get a number with 2 decimals after it (if that makes sense). In this case, you need to move the decimal point 7 places to the right, so the value of x is -7. The x value is negative if you need to move the decimal to the right and positive if you need to move the decimal to the left.

4. 18 inches
Please give an explanation (Do not just give an answer and take points or you will get reported)
Thank you :D
Given the perimeter, the numerical length of the rectangle is 49.5 inches.
Hence, option 3) 49.5 inches is the correct answer.
What is the length of the rectangle?The perimeter of a rectangle is expressed mathematically as;
P = 2( l + w )
Given the data in the question;
Let "x" represent the width of the rectangle.
Width w = xLength l = 3 × x = 3xPerimeter P = 132 inchesTo determine the length of the rectangle, first plug the given values into the formula above and solve for x.
P = 2( l + w )
132 = 2( 3x + x )
Apply distributive property
132 = 2(3x) + 2(x)
132 = 6x + 2x
132 = 8x
8x = 132
x = 132/8
x = 16.5
Now, the length of the rectangle will be;
Length l = 3x
Length l = 3( 16.5 )
Length l = 49.5 inches
Given the perimeter, the numerical length of the rectangle is 49.5 inches.
Hence, option 3) 49.5 inches is the correct answer.

You have a square blanket that has an area of 64 square feet. What are the dimensions of the blanket (length x width)?
The each side of the square will be 8.
Therefore, the area of a rectangle with a height of 4 cm and a length of 16 cm is 64 cm². Since a square is a rectangle with equal height and width, we need to find a number that when multiplied by itself equals 64... which is the square root of 64. That's 8.8x 8 = 64.
A square is a two-dimensional planar object in geometry that has four equal sides and four equal but 90 degree angles. The characteristics of a rectangle and a square are fairly comparable, however a rectangle only has its opposing sides equal. Therefore, a rectangle is only referred to as a square if its four sides are of the same length.

Chapter 7 of the Jiuzhang suanshu presents a problem of two linear equations involving acres of land and their respective prices. One of the two equations can be translated to:
300x + 300 x plus StartFraction 500 over 7 EndFraction left-parenthesis 87.5 right-parenthesis equals 10,000.y = 10000
If y = 87.5, what is the value for x?
The required value of x is 12.5 when y = 87.5
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given equation is,
300x + 500/7y = 10,000
Now for the value of x put the value of y which is 87.5 in the given equation we get,
300x + 500/(7*87.5) = 10,000
Solving we get,
300x + 500/612.5 = 10,000
Simplifying the fraction we get,
300x + 43,750/7 = 10,000
Dividing the fraction we get
300x + 6,250 = 10,000
Subtract 6,250 from both sides
300x + 6,250 - 6,250 = 10,000 - 6,250
Solving we get,
300x = 3,750
Divide both sides by 300
x = 3,750/300
Solving we get
x = 12.5
this is the required value of x when y = 87.5
Thus, the required value of x is 12.5 when y= 87.5

Indira is having 34 tulips, 68 daffodils and 102 hyacinths , altogether 204 flowers in her spring garden.
Given, In Indira's springtime garden, there are three times more hyacinths than tulips and half as many daffodils as tulips.
let the number of tulips be = x
the number of daffodils be = y
the number of hyacinths be = z
hence according to the question,
tulips are (x) = 1/2 (y) = y/2
hyacinths are (z) = 3(x) = 3x
therefore, total flowers = 204
tulips ₊ daffodils ₊ hyacinths = 204
y/2 ₊ y ₊ 3x = 204
substitute x value in the above equation.
y/2 ₊ y ₊ 3(y/2) = 204
take LCM
y ₊ 2y ₊ 3y = 408
6y = 408
y = 408/6
y = 68
hence the number of daffodils is 68.
now substitute y value in x = y/2
x = 68/2
x = 34
now substitute x value in z= 3x
z = 3(34)
z = 102
hence we get the number of tulips,daffodils and hyacinths as 34 , 68 and 102 respectively.
