Amy is wrapping a present

that is a rectangular prism.

The height is 18 inches, the

width is 16 inches and the

length is 20 inches. What is the

least amount of wrapping

paper, in square inches, that

Amy needs to wrap the

present

Answers

Answer 1

The least amount of wrapping paper that Amy needs to wrap the present is 1936in².

What is Surface Area?

Surface area is simply the amount of space covering the outside of a 3-dimensional object.

The surface area of a rectangular prism is expressed;

A = 2( wl + hl + hw )

Given the data in the question;

Height of the rectangular prism h = 18inWidth w = 16inLength l = 20inSurface area of the rectangular prism A = ?

To determine the least amount of wrapping paper that Amy needs to wrap the present in the shape of a rectangular prism, we substitute our given values into the expression above.

A = 2( wl + hl + hw )

A = 2( (16in×20in) + (18in×20in) + (18in×16in) )

A = 2( 320in² + 360in² + 288in² )

A = 2( 968in² )

A = 1936in²

Therefore, the least amount of wrapping paper that Amy needs to wrap the present is 1936in².

Which of the following ordered pairs are a solution for the equation y=2x−5 (2, 0)(-1, -7)(-9, -2)(1, 3)

Answers

Answer:

(- 1, - 7 )

Step-by-step explanation:

substitute the x- coordinate into the equation and if the value obtained is equal to the y- coordinate, then it is a solution

(2, 0 ) → y = 2(2) - 5 = 4 - 5 = - 1 ≠ 0 ← not a solution

(- 1, - 7 ) → y = 2(- 1) - 5 = - 2 - 5 = - 7 → solution to equation

(- 9, - 2 ) → y = 2(- 9) - 5 = - 18 - 5 = - 23 ≠ 2 ← not a solution

(1, 3 ) → y = 2(1) - 5 = 2 - 5 = - 3 ≠ 3 ← not a solution

Which angle is coterminal with a 120° angle?


A. An angle measuring 300°

B. An angle measuring-120°

C. An angle measuring 470°

D. An angle measuring 480°

Answers

An angle measuring 480° is coterminal with a 120° angle.

Coterminal angles

This classification represents angles that do not present the same value, but they present vertices and sides are identical. Also, if the angles are coterminal, then their sines, cosines and tangents are equal.

A coterminal angle can be found from the formula β = α ± 360 * w, where w is a positive integer.

Thus,

For w=1 and α=120°

        β = 120 ± 360 * 1

        β = 120 ± 360

       Then, β can be 120+360=480° or 120-360= -240°

For w=2 and α=120°

        β = 120 ± 360 * 2

        β = 120 ± 720

       Then, β can be 120+720=840° or 120-720= -600°

       Therefore, the answer to this question is option D.

Suppose that r (cos(θ) + i sin(θ)) is a third root of 27 (cos(π/5) + i sin(π/5)), i.e.

[r (cos(θ) + i sin(θ))]³ = 27 (cos(π/5) + i sin(π/5))

Expand the left side using de Moivre's theorem:

r³ (cos(3θ) + i sin(3θ)) = 27 (cos(π/5) + i sin(π/5))

Matching up real and imaginary parts, we have

r³ cos(3θ) = 27 cos(π/5)

r³ sin(3θ) = 27 sin(π/5)

Right away we see that r³ = 27 ⇒ r = 3, which eliminates A.

We also have

(r³ sin(3θ)) / (r³ cos(3θ)) = (27 sin(π/5)) / (27 cos(π/5))

tan(3θ) = tan(π/5)

3θ = tan⁻¹(tan(π/5))

3θ = π/5 + nπ

(where n is an integer)

θ = π/15 + nπ/3

Now,

• n = 0   ⇒   θ = π/15   ⇒   D is a third root

• n = 1   ⇒   θ = π/15 + π/3 = 2π/5

• n = 2   ⇒   θ = π/15 + 2π/3 = 11π/15   ⇒   C is a third root

Steps in the process of completing the square used to solve the given equation were discussed.

Given equation is:

[tex]5x+1=2x^{2} +9x[/tex], which is a quadratic equation

What is a quadratic equation?

Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where [tex]a\neq 0[/tex].

Taking all terms to the left side of the equation:

[tex]-2x^{2} -9x+5x+1=0[/tex]

[tex]-2x^{2} -4x+1=0[/tex]

[tex]2x^{2} +4x=1[/tex]

[tex]2(x^{2} +2x)=1[/tex]

To complete the square let us add 2 both sides

[tex]2(x^{2} +2x)+2=3[/tex]

[tex]2(x+1)^2=3[/tex].....(1)

So, equation (1) is the required answer.

Hence, steps in the process of completing the square used to solve the given equation were discussed.

HURRY 70 POINTS!! solve the system using substitution. show all work. {4x + 5y = 7 {y = 3x - 10

Answers

Answer:

(3, -1)

Step-by-step explanation:

Given

4x + 5y = 7y = 3x - 10

Subbing the value of y

4x + 5(3x - 10) = 74x + 15x - 50 = 719x = 57x = 3y = 3(3) - 10y = 9 - 10y = -1Solution is (3, -1)

Answer:

x = 3y = -1

Solution: (3, -1)

Step-by-step explanation:

Given equations:

[tex]4x + 5y = 7[/tex][tex]y = 3x - 10[/tex]

Step-1: Reorganize the equations with "y" on the L.H.S

[tex]\rightarrow \left \{ {{4x + 5y = 7} \atop {y = 3x - 10}} \right.[/tex]

[tex]\rightarrow \left \{ {{5y = 7 - 4x} \atop {y = 3x - 10}} \right.[/tex]

[tex]\rightarrow \left \{ {{5y = 7 - 4x} \atop y =-10 + 3x}} \right.[/tex]

Step-2: Make the x-variables the same on both equations

[tex]\rightarrow \left \{ {{3(5y = 7 - 4x)} \atop 4(y =-10 + 3x)}} \right.[/tex]

[tex]\rightarrow \left \{ {{15y = 21 - 12x} \atop 4y =-40 + 12x}} \right.[/tex]

Step-3: Add the equations

[tex]\rightarrow (15y + 4y) = (21 - 40) + (-12x + 12x)[/tex]

[tex]\rightarrow 19y = -19[/tex]

Step-4: Divide both sides by 19

[tex]\rightarrow \dfrac{19y}{19} = \dfrac{-19}{19}[/tex]

[tex]\rightarrow y = -1[/tex]

Step-5: Substitute the value of y into any equation

[tex]\rightarrow y = 3x - 10[/tex]

[tex]\rightarrow -1 = 3x - 10[/tex]

Step-6: Simplify the equation

[tex]\rightarrow -1 + 10 = 3x[/tex]

[tex]\rightarrow9= 3x[/tex]

Step-7: Divide 3 both sides

[tex]\rightarrow \dfrac{9}{3} = \dfrac{3x}{3}[/tex]

[tex]\rightarrow x = 3[/tex]

(Optional) Step-8: Convert the solution(s) into (x, y) form

[tex]\rightarrow (x, y) \rightarrow (x = 3; y=-1) \rightarrow (3,-1)[/tex]

Thus, the value of x and y is 3 and -1. The solution is (3, -1).

The number sentence that represents the amount of change Kate receives back is $20.00 - $18.92 = $1.08, The correct option is C)

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

For daises= $6.99

For soil potting =$3.98

For ceramic pot= $7.95

Now,

The correct answer is C) $20.00 - $18.92 = $1.08.

To find the amount of change Kate receives back, we need to subtract the total cost of her purchases from the amount of money she has. The total cost of her purchases is:

$6.99 + $3.98 + $7.95 = $18.92

Kate has $20.00, so we can find the amount of change she receives back by subtracting the total cost of her purchases from $20.00:

$20.00 - $18.92 = $1.08

Therefore, by algebra answer will be $1.08.

Answers

Using the binomial distribution, it is found that she should expect to roll the number cube 46 times.

What is the binomial probability distribution?

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

The expected number of trials until q successes is:

[tex]E_s(X) = \frac{q}{p}[/tex]

In this problem:

She wants 23 successes, hence q = 23.Of the six numbers on the cube, three are even, hence the probability of a success on a trial is of p = 3/6 = 0.5.

Then:

[tex]E_s(X) = \frac{23}{0.5} = 46[/tex]

Answer:

Step-by-step explanation:

The given situation can be modeled as a right triangle (see attached).

The interior angles of a triangle sum to 180°

⇒ angle at Jamie's position = 180° - 90° - 55° = 35°

To find the other measures (distances), we can use trig ratios.

where:

[tex]\theta[/tex] is the angleO is the side opposite the angleA is the side adjacent the angleH is the hypotenuse

To find the distance from Rachael to Jamie:

[tex]\implies \sf \tan(55^{\circ})=\dfrac{x}{45}[/tex]

[tex]\implies \sf x=45\tan(55^{\circ})[/tex]

[tex]\implies \sf x=64.267\:ft\:(nearest\:thousandth)[/tex]

To find the distance from Lance to Jamie:

[tex]\sf \implies \cos(55^{\circ})=\dfrac{45}{y}[/tex]

[tex]\sf \implies y=\dfrac{45}{\cos(55^{\circ})}[/tex]

Step-by-step explanation:

5x + (- x) - 1 = 11 - 2x , that is

5x - x - 1 = 11 - 2x

4x - 1 = 11 - 2x ( add 2x to both sides )

6x - 1 = 11 ( add 1 to both sides )

6x = 12 ( divide both sides by 6 )

x = 2

Answer:

The value of x is 2

Step-by-step explanation:

=> 5x + (-x) - 1 = 11 - 2x

=> 5x -x -1 = 11 - 2x

=> 4x - 1 = 11 - 2x

=> 4x+2x = 11+1

=> 6x = 12

We start off the multiples of 8 with 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104

The smallest positive 2 digit multiple is 16

The smallest 3 digit multiple is 104

We know 8 x 100 = 800, so we are still in 3 digits

Now we try 8 X 110 = 880

Now let's try 8 x 120 = 960

Now, 8 x 125 = 1,000 which is the smallest 4 digit number we can get

16 + 104 + 1000 = 1,120
