The final answer in scientific notation with the correct number of significant digits, and label with the correct units is 4.1 * 10^6 square ft
Part A: If half of the field is used to grow crops, what is the area of the portion of the field that has crops growing?The dimensions of the field are given as
Length = 3.3 * 10^3
Width = 2.5 * 10^3
From the question, we have
Half of the field is used to grow crops
This means that the area of the portion of the field that has crops growing is
Area = 1/2 * Length * Width
So, we have
Area = 1/2 * 3.3 * 10^3 * 2.5 * 10^3
Evaluate the product
Area = 4.125 * 10^6
Part B: Write the final answer in scientific notation with the correct number of significant digits, and label with the correct units.In (a), we have
Area = 4.125 * 10^6
The units are 2 significant digits
So, the result must also have 2 significant digits
This means that
Area = 4.1 * 10^6 square ft (when approximated)

The depth of a local river averages 16 ft, which is represented as |−16|. In January, it measured 4 ft deep, or |−4|, and in July, it was 18 ft, or |−18|. What is the difference between depths in January and July?
22 feet
14 feet
10 feet
2 feet
The difference between depths in January and July is 14 feets
The depth of a local river averages 16 ft., which is represented as |−16|.
In January, The depth of a local river measured 4 ft. deep, or |−4|
in July, The depth of a local river 18 ft., or |−18|
The average depth of a local river is measured as -16 because it is below the ground level and hence measured or plotted on -y axis
the difference between depths in January and July can be measured as
|−18| - |−4|
This is absolute sign which means every number inside this sign should be treated as positive
18 - 4 = 14

The value of x is 10.
Option C is true.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The expression is,
x/7 = 3x + 20/ 35
Now, We can solve as;
x/7 = 3x + 20/ 35
Multiply 35 in both side,
35 × x/7 = 35 × (3x + 20)/35
5x = 3x + 20
Subtract 3x both side,
5x - 3x = 3x + 20 - 3x
2x = 20
Divide 2 both side,
x = 10
Hence, The value of x is 10.

(a) A cylindrical glass jar whose height is 7 inches and whose diameter is 4 inches. Find the
capacity of the jar.
The volume of the glass jar is 87.96 cubic inch.
What is volume?Volume is a unit used to express how much three-dimensional space is occupied. It is usually represented quantitatively in different imperial measures, such as the gallon, quart, and cubic inch, or in SI-derived units like the cubic meter and liter. The cubic concept of length and volume are connected.
Volume is a three-dimensional measurement that's used to gauge a solid shape's capacity. It implies that the volume of a closed form determines how much space it may occupy in three dimensions.
The capacity of the jar is calculated as
Volume of cylinder = [tex]\pi r^{2}h[/tex] = [tex]\pi (2^{2})7[/tex] = [tex]28\pi[/tex] = 87.96 cubic inch.
Hence the capacity of the glass jar is 87.96 cubic inches.

One month Pablo rented 5 movies and 3 video games for a total of $39. The next month he rented 2 movies and 12 video games for a total of 75 . Find the rental cost for each movie and each video game.
we get that the rental cost for each movie is $ 4.5 and each video game is $ 5.5.
Let the cost of number of movies be x and the cost of number of video games be y.
So, the equations are:
5 x + 3 y = 39
2 x + 12 y = 75
2 x = 75 - 12 y
x = 75/2 - 6 y
Put it in the first one, we get that:
5 ( 75/2 - 6y) + 3y = 39
375/2 - 30 y + 3 y = 39
27 y = 187.5 - 39
27 y = 148.5
y = 148.5 / 27
y = $ 5.5
x = 75/2 - 6 y
x = 37.5 - 6 (5.5)
x = 37.5 - 33
x = $ 4.5
Therefore, we get that the rental cost for each movie is $ 4.5 and each video game is $ 5.5.

The perimeter of the rectangle below is 48 units. Find the length of side AB. Write your answer without variables.
The value of the variables are x is 5. and AB is 10
Given, the sides of the rectangle are:
length = 2x ₊ 2 and
breadth = 3x ₋ 2
perimeter of the rectangle = 48 units
2(l ₊ b) = 48
2(3x ₋ 2 ₊ 2x ₊ 1) = 48
2(5x ₋ 1) = 48
10x ₋ 2 = 48
10x = 48 ₊ 2
10x = 50
x = 50/10
x = 5
therefore, length = 2x ₊ 1 = 2(5) ₊ 1 = 11 and
breadth = 3x ₋ 2 = 3(5) ₋ 5 = 10

(b) A shopkeeper gave a bill to a customer. The bill was in two digits but was mistakenly interchanged thereby undercharging the customer by $45.00. If the sum of the digits is 9, find the actual value of the bill.
The actual value of the bill can either be $90 or $81 or $18 or $54 or $27 or $72 or $36 or $63 bill.
A digit is a part of a set that, when taken as a whole, makes up a numeration system. A digit is a number in that particular circumstance. The members of the set 0 through 9 make up the digits of the decimal (base-10) Arabic numbering system.
The bill of the customer was mistakenly interchanged by $45.
The sum of the two digits of the bill is 9.
Now,
9 = 9 + 0 or,
9 = 8 + 1 or,
9 = 1 + 8 or,
9 = 5 + 4 or,
9 = 2 + 7 or,
9 = 7 + 2 or,
9 = 3 + 6 or,

Find sin 0 and tan 0 if cos 0= 5/13, assuming that
[tex]0 \leqslant 0 < \ \frac{\pi}{2} [/tex]
sin( θ) = 12/13 and tan( θ) = 12/5.
sin θ, cos θ, tan θ are the three important trigonometry functions.
If θ lies in the first quadrant that is 0 ≤ θ < π/2, then the value of all trigonometry functions is positive.
The three most significant trigonometry functions are sin θ, cos θ, and tan θ.
If θ is located in the first quadrant, which is equal to θ/2, then all trigonometric functions have positive values.
The three important trigonometry identities are:
sin²( θ ) + cos²( θ ) = 1
1 + tan²( θ ) = sec²( θ )
1 + cot²( θ ) = csc²( θ )
Now we have,
cos θ = 5/13
Then,
sin²( θ ) + cos²( θ ) = 1
sin²( θ ) + ( 5/13 )² = 1
sin²( θ ) + 25/169 = 1
sin²( θ ) = 1 - 25/169
sin²( θ ) = ( 169 - 25)/ 169
sin²( θ ) = 144/ 169
sin( θ ) = √( 144/ 169 )
sin( θ ) = ± 12/13
Since, 0 ≤ θ < π/2
sin( θ ) = 12/13
Now we know,
tan(θ) = sin(θ) / cos(θ)
tan(θ) = ( 12/13 ) / ( 5/13)
