Samantha needs to pay a total of $250 in extra charges, which includes $168 for the state tax, $47 for the license plate, and $35 for the state safety and emission inspection.

To determine how much Samantha needs to pay in extra charges for her automobile purchase, we need to calculate each component separately and then sum them up. Firstly, we calculate the state tax by multiplying the purchase price by the tax percentage:

Tax = Purchase Price × Tax Rate

Tax = $4,200 × 0.04 = $168

Next, we add the fixed costs for the license plate and state safety and emission inspection:

Total Extra Charges = Tax + License Plate Fee + Inspection Fee

Total Extra Charges = $168 + $47 + $35 = $250

Therefore, Samantha needs to pay $250 in extra charges, not including the price of the car.

Answer: 169

Step-by-step explanation:

You just multiply 13 by 13

When simplifying 13 to the power of 2, you multiply 13 by itself, resulting in 13 x 13, which equals 169. This is known as squaring a number.

The question you've asked involves exponents, which is a way to express repeated multiplication of the same number. When you write 13 with a tiny 2 next to it, you're indicating that 13 should be multiplied by itself once, which is what squaring a number means. In other words, 13 to the power of 2 is 132, which is 13 × 13.

Let's simplify 132:

So, 132 equals 169. This process is using an integer power, which involves multiplying the base (in this case, 13) by itself as many times as indicated by the exponent (in this case, 2). This can apply to any number, where for example 53 (5 cubed) equals 5 × 5 × 5, which is 125.

The sum of any negative number and its opposite is 0. So your answer is 0.

The sum of any negative number and its opposite is equal to 0.

Answer:

[tex]y=\frac{1}{3}x+2[/tex]

Step-by-step explanation:

The given system of equation is;

[tex]x-3y=-6...(1)[/tex]

and

[tex]2x-7y=10...(2)[/tex]

To solve for y in the first equation; we add [tex]-x[/tex] to both sides.

[tex]-3y=-6-x[/tex]

We now divide through by -3;

This implies that;

[tex]y=\frac{1}{3}x+2[/tex]

[tex] \tan(60°) = \frac{x}{OR} \\ \Leftrightarrow x = OR \tan(60°) = OP \sqrt{3} = 12 \sqrt{3} [/tex]

Answer:

192

Step-by-step explanation:

To find how many phones are expected to be defective, we need to represent the values in a fraction.

[tex]\dfrac{x}{8000}=\dfrac{3}{125}[/tex]

x = number of defective phones

Now we can solve this using algebra.

To get the value of x we need to multiply both sides by 8000 to leave x alone.

[tex]x=\dfrac{3}{125}(8000)[/tex]

[tex]x=0.024(8000)[/tex]

[tex]x=192[/tex]

So around 192 cell phones are expected to be defective out of 8000 phones.

Step-by-step explanation:

The integers 5 and 5 sum to 10 and have the largest possible product.

___

The two numbers will be x and (10-x). Their product is x(10-x), which describes a downward-opening parabola with zeros at x=0 and x=10. The maximum (vertex) of that parabola is halfway between the zeros, at x=5. Both integers have the same value: 5. Their product is 25.

If there is a requirement the integers be distinct, then 6 and 4 are the integers of choice. Their product is 24.

Answer:

The possible solution that is obtained from the system of equation are:

(1,3) and (6,13)

Step-by-step explanation:

We are asked to find the solution set of the given system of equation as:

[tex]y=x^2-5x+7-----------(1)[/tex]

and [tex]y=2x+1--------(2)[/tex]

We know that the solution of the system of equations is the possible set of x and y-values that satisfy both the equations.

Or we may say the point of intersection of the graph that is obtained from both the equations.

We solve the system by substitution method as:

We put the value of y from equation (1) in equation (2) to obtain:

[tex]x^2-5x+7=2x+1[/tex]

which is further written by combining the like terms as:

[tex]x^2-5x-2x+7-1=0\\\\x^2-7x+6=0\\\\x^2-6x-x+6=0\\\\x(x-6)-1(x-6)\\\\(x-1)(x-6)=0[/tex]

Hence, we get the possible values of x as:

x=1   and x=6

   y=2×1+1=2+1  ( Putting the value of x in equation (2))

         y=3

          y=2×6+1

             y=13

Hence, the possible solutions are:

(1,3) and (6,13)

Answer:

  3x + 3y = 9

Step-by-step explanation:

Multiplying the given equation by 3 gives you ...

  3x + 3y = 9 . . . . . . matches the last choice

This is an equation for the same line as the given equation, so the lines will have infinitely many points in common (infinitely many solutions).

Answer:

3x + 3y = 9

Step-by-step explanation:

your calculations for volume (pi x r^2 × h) and surface area (2 × pi × r (h+r)) are correct. However your ratio are incorrect. From the formulas the ratio of surface area to volume would be r×h:2(h+r)

Answer:

48

Step-by-step explanation:

We assume that the die and coins are non-bias.

If you roll a die once, you have 6 possible outcomes (anything from 1-6).

If you flip 3 coins once, you have 2 possible outcomes for each coin (either heads or tails). Multiply those 3 possibilities (2x2x2), you get 8.

Multiply 8 with 6, and you get 48 possible outcomes in sample space.

*In the sample space shown below, do the same combinations to all roll die outcomes to get the whole sample space (i.e., 2TTT, 3TTT, 4TTT etc.).

Answer:

It is B. hyperbola, 45 degrees.

SteIt is p-by-step explanation:

If we rotate the standard form  x^2 - y^2 = 1 through 45 degrees we get xy = 1/2.

xy = -2.5 comes from x^2 - y^2 = -5  being rotated 45 degrees.

Answer:

The correct option is b

Step-by-step explanation:

The given equation is

[tex]xy=-2.5[/tex]

It can be written as

[tex]xy+2.5=0[/tex]              .... (1)

The general forms of conic is

[tex]Ax^2+Bxy+Cy^2+Dx+Ey+F=0[/tex]             .... (2)

From (1) and (2), we get

[tex]A=0,B=1,C=0,D=0,E=0,E=2.5[/tex]

[tex]B^2-4AC=1-4(0)(0)=1>0[/tex]

Since the value of B²- 4AC > 0, then it is hyperbola.

The formula form angle of rotation is

[tex]\tan 2\theta=\frac{B}{A-C}[/tex]

[tex]\tan 2\theta=\frac{1}{0-0}[/tex]

[tex]\tan 2\theta=\infty[/tex]

[tex]\tan 2\theta=\tan (90^{\circ})[/tex]

[tex]2\theta=90^{\circ}[/tex]

[tex]\theta=45^{\circ}[/tex]

The angle of rotation is 45°. Therefore the correct option is b.

Answer:

The answer is 1.4 miles ⇒ answer (d)

Step-by-step explanation:

* Let the balloon is at the vertex A, and the soccer fields

  at vertex B and the football field at vertex C

∴ m∠B = 20° 15' = 20.25°

∴ m∠C = 62° 30' = 62.5°

∴ m∠A = 180 - 20.25 - 62.5 = 97.25°

∵ BC = 4 miles

* By using the sin Rule:

∵ AC/sin(B) = BC/sin(A)

∴ AC = (BC)(sinB)/sin(A)

∴ AC = [4 × sin(20.25)] ÷ sin(97.25) = 1.395 ≅ 1.4 miles

∴ The distance from the balloon to the football filed = 1.4 miles

Answer:

[tex]6\sqrt{2}[/tex]

Step-by-step explanation:

we have

[tex]3\sqrt{24} -2\sqrt{54}+2\sqrt{18}[/tex]

we know that

[tex]\sqrt{24}=\sqrt{2^{3}3}=2\sqrt{6}[/tex]

[tex]\sqrt{54}=\sqrt{3^{3}2}=3\sqrt{6}[/tex]

[tex]\sqrt{18}=\sqrt{3^{2}2}=3\sqrt{2}[/tex]

Substitute

[tex]3(2\sqrt{6}) -2(3\sqrt{6})+2(3\sqrt{2})[/tex]

[tex](6\sqrt{6}) -(6\sqrt{6})+(6\sqrt{2})[/tex]

[tex]6\sqrt{2}[/tex]

When simplifying the square roots in the expression 3sqrt(24) - 2sqrt(54) + 2sqrt(18), we find that the simplified solution is 6sqrt(2).

To simplify the radical expression 3 sqrt 24 - 2 sqrt 54 + 2 sqrt 18, we first need to break down each square root into its simplest form. In order to do this, we look for perfect-square factors (numbers like 4, 9, 16, 25 that have an integer as a square root) within each number:

3sqrt(24) = 3sqrt(4*6) = 6sqrt(6)

2sqrt(54) = 2sqrt(9*6) = 6sqrt(6)

2sqrt(18) = 2sqrt(9*2) = 6sqrt(2)

Because the sqrt(6) terms are like terms we can combine those, and then include the sqrt(2) term:

6sqrt(6) - 6sqrt(6) + 6sqrt(2) = 6sqrt(2).
