The total cost of the birdfeeder which poni wants to buy including the sales tax is $21.54.

Given poni wants to purchase a birdfeeder that costs $19.95.

sales tax rate in her city is = 8.12%

total cost of the birdfeeder = ?

The pre-tax price of an item must first be multiplied by the sales tax percentage once it has been converted into a decimal form in order to determine the amount of sales tax that will apply to the purchase. To get the item's final cost, the sales tax must first be computed, and then it must be added to the pre-tax price.

sales tax rate = 8.12% = 0.0812

Round it off to two decimal places.

= 0.08

Now, in order to determine the cost of the sales tax, we must multiply the item's pre-tax price by this amount.

sales tax = 0.08×$19.95

sales tax = $1.596

Since our total is in dollars and cents, round to two decimal places.

sales tax = $1.59

now total cost = pre tax value+sales tax.

= $19.95+1.59

=$21.54

Hence the total cost of the birdfeeder is $21.54.

The triangle in the right side of the first row, the triangle in the left side of the second row and the triangle in the left side of the third row are labeled correctly.

Triangles can be defined in terms of their base and their height. Both are linear measures. The base is one side of the triangle and the height is a line perpendicular to the base that meets the vertex opposite to the base.

Based on this explanation we find that the triangle on the right of the first row, the triangle on the left of the second row and the triangle on the left of the third row are labelled correctly.

Answer:

Domain: [-4, 5]
Range: [-3, 3]

Step-by-step explanation:

Domain is the set of all permissible x values ie the values of x for which the function is defined.

Range is the set of all values of the function ie f(x) or y in tis graph for the domain

Looking at the graph we can see that the smallest value for x is -4 and the largest value is +5
Domain is [-4, 5]

For these values, y ranges from smallest of -3 to largest of + 3
So Range is [-3, 3]

This suggests that the equilateral triangle's sides' measurements remain unaltered.

A coordinate plane is a surface with two dimensions made up of two number lines. It is created when the origin, the point at which the X-axis and Y-axis cross, is reached. To locate points, one uses the numbers on a coordinate grid.

Sides = 5 inches

Given

Sides = 5 inches

Translation = 3 units (down) and 2 units (right)

Required

Determine the length of one side after translation

It should be emphasized that just the position of a shape, line, or object changes when it is translated by moving its position, not its length.

This suggests that the equilateral triangle's sides' measurements remain unaltered.

Hence:

Sides = 5 inches

Lori will make more than Darryl, then the after 10 years Lori will have make $27.00 more in their account.

Darryl deposits into a savings = $1,500

Account that has a simple interest rate = 2.7%.

Lori deposits into a savings = $1,400

Account that has a simple interest rate = 3.8%.

Let us assume,

[tex]P_{1}[/tex] = $1,500

[tex]r_{1}[/tex] = 2.7%.

[tex]r_{1}[/tex] =  2.7/100

[tex]r_{1}[/tex] = 0.027

After 10 years = t = 10years

The formula to calculate simple interest is,

[tex]A_{1}[/tex] = [tex]P_{1} (1+r_{1} t)[/tex]           (Equation-1)

[tex]P_{1}[/tex] = Principal amount

[tex]r_{1}[/tex] = rate of interest ( in decimal )

t = time

First we calculate Darryl's deposit,

So we can substitute values in the equation-1,

[tex]A_{1}[/tex] = 1,500(1 + 0.027×10)

[tex]A_{1}[/tex] = 1,500 ( 1+0.27 )

[tex]A_{1}[/tex] = 1,500 × 1.27

[tex]A_{1}[/tex] = $1905

Now we will calculate Lori's deposit,

[tex]A_{2}[/tex] = [tex]P_{2} (1+r_{2} t)[/tex]                (Equation-2)

[tex]P_{2}[/tex] = $1,400

[tex]r_{2}[/tex] = 3.8%.

[tex]r_{2}[/tex] =  3.8/100

[tex]r_{2}[/tex] = 0.038

So we can substitute values in the equation-2,

[tex]A_{2}[/tex] = 1,400 ( 1 + 0.038 × 10 )

[tex]A_{2}[/tex] = 1,400 ( 1 + 0.38 )

[tex]A_{2}[/tex] = 1,400 × 1.38

[tex]A_{2}[/tex] = $1,932

Darryl will make money after 10 years = $1905

Lori will make money after 10 years = $1,932

Hence,

Lori will make more than Darryl,

Then the difference will be = 1,932 - 1,905 = $27

Therefore,

After 10 years Lori will have make $27.00 more in their account.

The number of birds in different regions is a discrete variable.

Discrete data can only have certain values. There may be an endless number of those values, but each one is distinct, with no grey space in between. Discrete data can be numerical, such as the number of apples, or categorical, such as red or blue, male or female, or good or bad.

The discrete variable is the number of birds.

This variable is not continuous in this case because we count the number of birds rather than measure them.

The continuous variables are measured rather than counted. For example, weight, height, and so on.

As a result, the quantity of birds in various places is a discrete variable.

ANSWER FOR QUESTION 7

X=1,Y=1

Step-by-step explanation:

2x+3y=5.

4x-y=3.

In this question, we simply find the value of y from equation 2 because by doing this there will be no term in the denominator so it quiet be easy for us.

y= -3+4x(4x-3) put in eq 1

2x+3(4x-3)=5

2x+12x-9=5

14x=14

divide 14 into both sides

x=1.

put in eq 1 or eq 2 to find the value of y Answer will be the same.

let's put in eq 1

2(1)+3y=5

3y=3

divide 3 into both sides

y=1.

Same for question 8 and 9.

The value ∠L, ∠M and ∠N is 59°, 105° and 16° respectively.

∠L = (4x - 5)°, ∠M = (7x-7)° and ∠N = x°

The summation of all three angles of a triangle is equal to 180°

∠L+ ∠M + ∠N = 180°

4x - 5 + 7x -7 + x = 180

12x - 12 = 180

12x = 192

x = 192/12

x = 16

∠L = 4x - 5

= 4(16) - 5

= 64 - 5

= 59°

∠M = 7x - 7

= 7(16) - 7

= 112 - 7

= 105°

∠N = x = 16°

Therefore the value ∠L, ∠M and ∠N is 59°, 105° and 16° respectively.

The given two equations represent that 6x-15y=15  is equal to y=2/5x-1 And they have the same slope 2/5.

Equations are logical statements in mathematics that are denoted by an equals (=) sign and two algebraic expressions on either side of it. It is demonstrated that the expressions on the left and right are equal to one another.

All mathematical equations start with LHS = RHS (left hand side = right hand side). To find the value of an unknown variable, or unknown quantity, you can solve equations. If the statement does not contain a "equal to" symbol, it is not an equation. It will be considered as an expression.

We have been asked to find the value of x and y in 6x-15y=15 and y=2/5x-1

Let solve for y = 2/5x-1

in  6x - 15y = 15

⇒ 6x - 15(2/5x-1) = 15

⇒ 6x - 6x  + 15 = 15

⇒ 15 = 15

⇒ This mans they have slope

⇒ 6x - 15y = 15 in y-intercept form

⇒ 15y = 6x - 15

⇒ 15y = 6x - 15

⇒ y = (6x - 15)15

⇒ y = 2/5x - 1

Thus, 6x-15y=15  is equal to y=2/5x-1 And they have the same slope 2/5.
