(a) What is the value of Expression 1?
(b)Insert parentheses in Expression 2 so that it has a value of 2936. Then
show why your expression has a value of 2936.
Answer:
The value of the expression 1 (42 - 6 - 8 - 3 + 2³) will be 33. Then the value in the parentheses will be 2206.77.
What is the value of the expression?When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The expression 1 is given below.
⇒ 42 - 6 - 8 - 3 + 2³
Then the value of the expression 1 will be
⇒ 42 - 6 - 8 - 3 + 2³
⇒ 42 - 6 - 8 - 3 + 8
⇒ 33
The expression 2 is given below.
⇒ 720 + 2 + 7.23
Insert parentheses in Expression 2 so that it has a value of 2936. Then the value in the parentheses will be
720 + 2 + 7.23 + (x) = 2936
729.23 + x = 2936
x = 2206.77

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
hence we get the value of x as 5

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

(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.

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

Active dry yeast and bread machine yeast were not available in stores during the coronavirus pandemic. Fleischmann’s attempted to staff two shifts to produce enough active dry yeast to put some yeast back on the market. If the first shift produced 1½ times as many yeast packets as the second shift, and 5,600 packets of yeast were produced during the month, how many packets of yeast were produced on each shift
Based on the rate of the production of yeast packets by the two shifts of Fleischmann’s, the packets produced in each shift were:
First shift - 3,360 packets Second shift - 2,240 packets What number of yeast packets were produced?Assuming that the number of yeast packets produced in the second shift is x, the number produced in the first shift would be:
= 1½ × x
= 1.5x
The number of yeast packets in the second shift is:
x + 1.5x = 5,600
2.5x = 5,600
x = 5,600 / 2.5
= 2,240 packets
The number of yeast packets in the first shift is:

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)
tan(θ) = 12/5

Answer:
5/18
Step-by-step explanation:
1/2 × 9/9 = 9/18

This means we have 9/18 and 4/18 left in the circle. Because these fractions have a common denominator, we can now subtract them from the whole to find the shaded portion:
18/18 - 9/18 - 4/18 = 5/18
