The percentage equation states that the part equals the percent multiplied by the whole.

What is percent?

A percentage is a number that indicates how much is 100 and can also be expressed as a decimal or fraction.

What is Percentage Equation?

Percentage equations allow you to find parts or ratios of amounts (or wholes). Percentages are specified with a % sign after the number of hundredths.

The formula for percentage equation is given below

Percent=(Part/Whole)x100

Example: 45 is 60% of what number?

Modifying the above percentage equation, we get

Whole= (Part/Percent) x 100

⇒Whole= (45/60) x 100

⇒Whole= (3/4) x 100

⇒Whole= 3 x 25

⇒Whole= 75

f) No.

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows: Expression: (Math Operator, Number/Variable, Math Operator)

Given that

the number of yellow tile in figure 1 is 8.

The number of yellow tile in figure 2 is 12.

The number of yellow tile in figure 3 is 16.

(a) The table is

Figure                     1             2            3  

Number of tiles      8            12          16

(b)

The number of tiles increase at a constant rate.

The rate is (12 - 8) = (16 - 12) = 4

The relation with the figure and number of tiles is

The number of tiles is = 4 + (the number of figure - 1)4

C)

Assume that y represents total number of tiles.

x = Number of figure

Rewrite "The number of tiles is = 4 + (the number of figure - 1)4" in term of x and y:

y = 8 +(x - 1)4

y = 8 + 4x -4

y = 4x + 4

d) Putting x = 24 in y = 4x + 4

y = 4×24 + 4

y = 96 + 4

y = 100

e)

Putting y = 176 in y = 4x + 4

176 = 4x + 4

Subtract 4 from both sides:

172 = 4x

Divide both sides by 4

x = 43

f)

Putting y = 54 in y = 4x + 4

54 = 4x + 4

Subtract 4 from both sides:

50 = 4x

Divide both sides by 4

x = 50/4

The value of x is not a whole number. Thus it is not possible that a figure has with 54 yellow tiles.

The equation by using x represent the number of years and y represent the number of fish is y=900×(2)ˣ.

Given that,

James is keeping an eye on the fish population in the pond he created. He constructed a pond and added 900 fish to it. Every year, the fish population doubles.

We have to find the equation by using x represent the number of years and y represent the number of fish.

We know that,

We get

Number of fish at starting =900

Number of fish after 1 year =900×2=1800

Number of fish after 2 year =1800×2=3600=900×(2)²

Number of fish after 3 year =3600×2=7200=900×(2)³

So,

Here we can see that the number of fish are in Geometric progression (G.P) with a=900 and r=2

So,

Tₙ=arⁿ⁻¹

We get

y=900×(2)ˣ

Therefore, The equation by using x represent the number of years and y represent the number of fish is y=900×(2)ˣ.

The measure of an interior angle (in degrees) of an [tex]n[/tex]-sided regular polygon is [tex]\frac{180(n-2)}{n}[/tex].

[tex]n=45 \implies \frac{180(n-2)}{n}=\boxed{172^{\circ}}[/tex]

The degree measure of one angle of a 45-sided regular polygon is 172°.

When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.

Here, the polygon has 45 sides.

To find the measure of an interior angle of a regular polygon,

we make use of the formula for each angle = (n - 2) × 180 / n.

The formula calculated is only valid in cases of regular-sided polygons.

n =  45 substituting the value of n to the formula.

(n - 2) × 180 / n

= 180 ( 45-2) / 45

= 180 x 43 / 45

= 7740 / 45

= 172°

Therefore, the measure of one angle is 172°.

Two possible numbers are 6 and 12.

6 would mean she bought one box, and 12 would mean she bought 2 boxes.

Step-by-step explanation:

in a fraction as exponent the numerator defines the pure exponent of the base, and the denominator gives the degree of root of the base.

[tex] \sqrt[5]{y^{3} } [/tex]

Answer:

[tex] \sqrt[5]{ {y}^{3} } [/tex]

Step-by-step explanation:

When converting an expression with a fractional exponent to its radical form, the base number goes inside the radical(which means it becomes the radicand) along with the numerator(which remains an exponent).

Based on the Pythagorean theorem, the set of side of lengths that will form a right triangle are:

2, √5, 3

2, 2, √8

Based on the Pythagorean theorem, any set of side lengths that will form a right triangle would have the following relationship:

b² = a² + c², where b is the longest side or the hypotenuse of the right triangle and "b and c" are the lengths of the legs of the triangle.

For side lengths, 4, 8, and 12, we have:

12² = 4² + 8²

144 = 16 + 64

144 = 80 [not true, cannot form a right triangle]

For side lengths, 2, √5, 3, we have:

3² = (√5)² + 2²

9 = 5 + 4 [true, this set will form a right triangle]

For side lengths, 2, 2, √8, we have:

To solve this expression, we need to use the rules of order of operations, which dictate the order in which mathematical operations should be performed. The order of operations is typically abbreviated using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

Using the order of operations, we can solve the expression as follows:

64 - (-2)⁵ ÷ 2³ + (-1)³ · (0.5)²

= 64 - (-2)⁵ ÷ 8 + (-1)³ · 0.25

= 64 - (-32) ÷ 8 + (-1)³ · 0.25

= 64 + 32 + (-1)³ · 0.25

= 96 + (-1)³ · 0.25

A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.

In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.

The depreciation expense is the periodic recognition of the cost for a long-term asset over its useful life.

The costs of long-term assets are spread over their estimated life through depreciation, depletion, or amortization.

The various depreciation methods include:

The cost of the delivery truck on January 1, 2022 = $26,000

Expected salvage value = $1,280

Depreciable amount = $24,720

Estimated useful life = 103,000 miles or 10 years

Depreciation Expenses:

Straight-line method = $2,472 annually ($24,720/10)

Units of activity method per mile = $0.24 ($24,720/103,000)

Answer

2617.

Step-by-step explanation

To estimate the number of people that can fit into a circular arena with a diameter of 100 yards, we first need to find the area of the arena. To do this, we can use the formula for the area of a circle, which is equal to pi times the radius squared. Since the diameter of the arena is 100 yards, the radius would be half of that, or 50 yards. Plugging this value into the formula for the area of a circle, we get:

Area = pi * 50^2

Since pi is approximately equal to 3.14, we can plug this value into the equation to get:

Area = 3.14 * 50^2

This simplifies to:

Area = 3.14 * 2500

Which gives us an area of approximately 7850 square yards.

Since one person requires a personal space of 3 square feet, we can divide the total area of the arena by 3 to find the number of people that can fit in the arena. This gives us:

7850 square yards / 3 square feet/person = 2616.666... people

Rounded to the nearest whole number, this means that approximately 2617 people could fit in the circular arena with a diameter of 100 yards.

The length of the segment AE on the triangle is 45/7

From the question, we have the following parameters that can be used in our computation:

DE parallel to BC,

Also, we have

AD/DB=3/4

The above parameters mean that

AD/AB = AE/AC

Also, we know that

AB = AD + DB

From the ratio values, we have

AB = 3 + 4

Evaluate the sum

AB = 7

Updating the initial ratio, we have

AE/15 = 3/7

Multiply both sides by 15

So, we have the following representation

AE = 15 * 3/7

Evaluate the products

AE = 45/7
