The number of square cm of cheese layers that Anna needs to put on the pizza is  30.25π square cm.

What is the area of a circle?

In geometry, the area of a circle is the space occupied by the circle.

To find the area of a circle having radius "r", we can use the formula.

               Area of a circle = π×r².

In the given question, the diameter of the pizza is 11 cm.

so the radius will be = 11/2 = 5.5 cm.

                Area of the pizza = π×r²

                                              = π×(5.5)²

                                              = 30.25π square cm.

Hence, the number of square cm of cheese layers that need to be put on the pizza is  30.25π square cm.

Answer: (1/3)x - 8

Step-by-step explanation:

one - third means 1/3

one - third of a number means (1/3)x

       ( x being the number )

Eight less means -8

Eight less than 1/3 of an number is (1/3)x - 8

Answer:

B (x = 3 + √5)

Explanation:

x² + 9 = 5

Take square root of both sides

x + 3 = ± √5

Add 3 to both sides

x = 3 + √5 or x = 3 - √5

Sandy earn 306.9 dollars in commission and 1739.1 dollars in hourly wages.

Sandy works at a clothing store. She makes $9 per hour plus earns 15% commission on her sales.

She worked 71 hours over the last two weeks and had a total of $2,046 in sales before taxes.

The amount she will earn in her hourly wages and commission is as follows:

amount earn in commission = 15% of 2046

amount earn in commission = 15 / 100 × 2046

amount earn in commission = 30690 / 100

amount earn in commission = 306.9 dollars

Therefore,

amount earn in hourly wages = 2046 - 306.9

Step-by-step explanation:

The transformations of g(x) that would result in odd functions are (a)-g(x)   , (b)g(2x)  and (d)g(–x) ,

In the question ,

it is given that,

the function is g(x) = 3x³ + x

We know that the function f(x) is called an odd function if f(-x) = -f(x) .

Option(a)

the transformation is given as -g(x)

-g(x)  = -(3x³ + x) = -3x³ - x

g(-x) = 3(-x)³ + (-x) = -3x³ - x

so , this is odd function .

Option (b)

the transformation is given as g(2x)

g(-2x) = 3(-2x)³ + (-2x) = -24x³ - 2x

-g(2x) = -{3(2x)³ + (2x)} = -( 24x³ + 2x ) = -24x³ - 2x

so , this is  odd function .

Option (c)

the transformation is given as g(x)-3

(g(-x) - 3) =  3(-x)³ + (-x) - 3 = -3x³-x-3

-(g(x) - 3) = -{(3x³ + x) -3} = -3x³ - x +3

So, so , this is not an odd function

Option (d)

the transformation is given as g(-x)

g(-(-x)) = g(x) = 3x³+x

-g(-x) = -(3(-x)³ + (-x)) = -(-3x³ - x) = 3x³+x

so , this is odd function .

Therefore, the odd transformations are -g(x)   , g(2x)  and g(–x) ,

Means if a number is bigger than other number.

The linear equation in the slope-intercept is:

y = (-1/5)*x  - 26/5

And it can be written as:

y = (-1/5)*(x + 1) - 5

We can write the equation for line L as:

y = a*x +b

Where a is the slope and b is the y-intercept.

Two lines are perpendicular if the product between the slopes is equal to -1.

So if we want our line to be perpendicular to y= 5x, then we must have:

a*5 = -1

a = -1/5

So our line is something like:

y = (-1/5)*x + b

And the line passes through (-1, -5), replacing these values:

-5 = (-1/5)*-1 + b

-5 = 1/5 + b

-5 - 1/5 = b

-26/5 = b

The percentage increase in Hayley's fuel bills from 2021 to 2022 is equal to 17.105%.

What is a Percentage Increase?

The phrase "percentage increase" (or "percentage change" in general) refers to the difference between the final and starting values of a quantity, expressed as a percentage of that number's original value.

Steps to Calculate Percentage Increase?

Here, in the question, it is given that,

The original amount (X) or the fuel bill in 2021 is £76.

The new amount (Y) or the fuel bill in 2022 is £89.

So, the Increase (I) in the fuel bills from 2021 and 2022 is calculated as,

[tex]I=Y-X\\\implies I=89-76\\\implies I=13[/tex]

Now, we can calculate the percentage increase in fuel bills from 2021 to 2022 as,

[tex]\%I=\frac{I}{X} \times 100\\\implies \%I=\frac{13}{76} \times 100\\\implies \%I=17.105\%[/tex]

Therefore, the percentage increase in Hayley's fuel bills from 2021 to 2022 is 17.105%.
