A shirt is originally priced at $24.5. the shirt goes on sale for 30%off the original price. How much money in dollars does the shirt cost including 7% on the tax on the slaeprice

Answer:

136.2

Step-by-step explanation:

Plugin x = 18 in the polynomial.

P(x) = 0.02x³ + 0.04x² + 0.3x + 1.2

P(18)= 0.02*(18)³ + 0.04*(18)² + 0.3*18 + 1.2

      = 0.02 * 5832  + 0.04*324 + 5.4 + 1.2

      = 116.64 + 12.96 + 5.4 + 1.2

      = 136.2

The cost of one sandwich is $3.90

The cost of one deknk is $1.50

hopefully this is correct

The system of equations are

The cost of one sandwich x = $ 3.90

The cost of one drink y = $ 1.50

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the cost of one sandwich be x

Let the cost of one drink be y

Now , the equation will be

A customer ordered three sandwiches and two drinks for $14.70

So , 3x + 2y = 14.70   be equation (1)

And , Another customer bought two sandwiches and four drinks for $13.80

So , 2x + 4y = 13.80   be equation (2)

On simplifying the equations , we get

Multiply equation (1) by 2 , we get

6x + 8y = 29.4   be equation (3)

Subtracting equation (2) from equation (3) , we get

4x = 15.6

Divide by 4 on both sides of the equation , we get

x = $ 3.90

So , the cost of one sandwich is $ 3.90

And ,

Substituting the value of x in equation (1) , we get

3x + 2y = 14.70

3 ( 3.90 ) + 2y = 14.70

11.70 + 2y = 14.70

Subtracting 11.70 on both sides of the equation , we get

2y = 3

Divide by 2 on both sides of the equation , we get

y = $ 1.50

So , the cost of one drink is $ 1.50

Hence , the cost of one sandwich and one drink is $ 3.90 and $ 1.50 respectively

Answer:

NM = 15

Step-by-step explanation:

Given a secant and a tangent from an external point to the circle, then

The square of the measure of the tangent is equal to the product of the secant's external part and the entire secant, that is

(x + 3)² = (x - 3)(x - 3 + 16)

(x + 3)² = (x - 3)(x + 13) ← expand both sides using FOIL

x² + 6x + 9 = x² + 10x - 39 ( subtract x² + 10x from both sides )

- 4x + 9 = - 39 ( subtract 9 from both sides )

- 4x = - 48 ( divide both sides by - 4 )

x = 12

Then

NM = x + 3 = 12 + 3 = 15

x + 3 = 3(x + 3)

Step-by-step explanation:

Aftab's age = x

daughter's age = y

According to question,

x - 7 = 7(y - 7)

and,

x + 3 = 3(x + 3)

Jennifer factored it completely because she pulled out the common factor  of the three terms, which 2.

This simplifies the trinomial to 2(2x^2-3x-2) and then this factors to be 2(x − 2)(2x + 1)

Answer:

I agree with Jamie

Step-by-step explanation:

Given the inequality expression -2°C > -5°C, to compare both temperatures, we are to determine whether we agree or disagree with him.

Note that negative values that are closer to zero on the number line are greater than those that are far from zero. Hence, since -2 is closer to zero on the number line than -5, this means that -2 is greater than -5 hence I agree with Jamie's temperature value comparison.

Answer:

He walked Ms. Evans' dog 3.89 miles.

Step-by-step explanation:

From the information provided, you know that the total distance that he walked both dogs is 17.5 miles, which can be expressed as:

x+y=17.5, where:

x is the distance he walked  Mr. Jackson's dog

y is the distance he walked  Ms. Evans' dog

Also, the statement indicates that he walked Mr. Jackson's dog 3.5 times farther than he walk Ms. Evans' dog and you can write the following equation:

x=3.5y

Now, you can replace x=3.5y in the first formula and solve for y to find how far he walked Ms. Evans' dog:

3.5y+y=17.5

4.5y=17.5

y=17.5/4.5

y=3.89

According to this, the answer is that he walked Ms. Evans' dog 3.89 miles.

Answer:

£707.8

Step-by-step explanation:

Given data

Price=  £800

Rate= 4%

Time= 3 years

Let us apply the compounding formula

A=P(1-r)^r-------------Note the negative sign is because of depreciation

substitute

A= 800(1-0.04)^3

A= 800(0.96)^3

A=800*0.884736

A=  £707.8

Hence the value will be £707.8

I used a calculator

Answer:

a. Sin θ = y/r

b. csc θ = r/y

c. cos θ = x/r

d. sec θ = r/x

e. tan θ = y/x

f. cot θ = x/y

g. x² + y² = 1

Step-by-step explanation:

Where (x, y) are the x and y coordinates of the position with radius r and angle θ measured from the positive x axis. y is the opposite side to the angle θ and x is the adjacent side to the angle θ and r is the hypotenuse side of the right-angled triangle formed by x, y and r. Also, x² + y² = r²

a. Sin θ = opposite/hypotenuse = y/r

b. csc θ = hyotenuse/opposite = 1/Sin θ = r/y

c. cos θ = adjacent/hypotenuse = x/r

d. sec θ = hypotenuse/adjacent = 1/cos θ = r/x

e. tan θ = opposite/adjacent = y/x

f. cot θ = adjacent/opposite = 1/tan θ = x/y

g. Equation of the Circle: _ the unit circle (r = 1),

Since x² + y² = r² ,for a unit circle, r = 1. So,

x² + y² = 1²

x² + y² = 1

Answer:

Area = (8 + 2x)² mi²

Step-by-step explanation:

Length of the side of a park = 8 mi

Width of the road around the park = x mi

Length of one side of the park with the road = (8 + 2x) mi

Area of the park with road = (side)²

                                            = (8 + 2x)²

Therefore, combined area of the park and road is (8 + 2x)² square miles.

Answer:

1.y=3x-7

2.y=-3x-5

3.y=x+2

4.y=-4x+1

5.y=x+6

6.y=1/2x+5

Step-by-step explanation:

parallel lines have the same slope

1.y-2=3(x-3)

y-2=3x-9

y=3x-9+2

y=3x-7

2.y-(-2)=-3(x-(-1))

y+2=-3x-3

y=-3x-3-2

y=-3x-5

3.y-1=1(x-(-1)

 y-1=1(x+1)

 y-1=1x+1

y=1x+1+1

y=1x+2

4,y-(-3)=-4(x-1)

y+3=-4x+4

y=-4x+4-3

y=-4x+1

5.y-2=1(x-(-4)

 y-2=1(x+4)

y-2=1x+4

y=1x+4+2

y=1x+6

6.y-3=1/2(x-(-4)

 y-3=1/2(x+4)

 y-3=1/2x+4/2  simplify 4/2 to 2/1 =2

 y=1/2x+2+3

 y=1/2x+5
