Answer:

From the information, we know that the plate will hold 3 pieces of sushi, each with a diameter of 1 1/2 inches, and there be 1/2 inch space from the edge of the of the suchi to the edge of the plate.

The diamter of the suchi plates we need to puchase should be the sum of the diameter of the sushi and the the space between them and the edge of the plate:

  (3 . 1 1/2) + (2 . 1/2)

= (3 . 3/2) + 1

= 9/2 + 1

= 9/2 + 2/2

= 11/2 = 5.5 (inches)

Answer:

From the information, we know that the plate will hold 3 pieces of sushi, each with a diameter of 1 1/2 inches, and there be 1/2 inch space from the edge of the of the suchi to the edge of the plate.

The diamter of the suchi plates we need to puchase should be the sum of the diameter of the sushi and the the space between them and the edge of the plate:

  (3 . 1 1/2) + (2 . 1/2)

= (3 . 3/2) + 1

= 9/2 + 1

= 9/2 + 2/2

= 11/2 = 5.5 (inches)

Answer:

It makes sense for the answer to be 86 degrees since it's almost a right angle.

Answer:

The correct answer is option C.   86°

Step-by-step explanation:

From the figure we can see a circle.

To find the measure of <PRQ

Consider the triangle PQR,

<PRQ  = <PTR + <RPT

From the figure we get,

<PTR = 102/2 = 51

<RPT = 70/2 = 35

<PRQ  = <PTR + <RPT

51 + 35 = 86°

Therefore the correct answer is option C.   86°

Answer:

The company sold 100 widgets and 250 gizmos.

Step-by-step explanation:

Let [tex]x_1[/tex] be the number of widgets sold and [tex]x_2[/tex] be the number of gizmos sold.

We are told that the company sold 350 items. We can represent this information in an equation as:

[tex]x_1+x_2=350...(1)[/tex]

We have been given that a each widget sold for $35 and each gizmo sold for $22. The company sold 350 items for a total of $9,000.

We can represent this information in an equation as:

[tex]35x_1+22x_2=9,000...(2)[/tex]

From equation (1), we will get:

[tex]x_2=350-x_1[/tex]

Substitute this value in equation (2):

[tex]35x_1+22(350-x_1)=9,000[/tex]

[tex]35x_1+7,700-22x_1=9,000[/tex]

[tex]13x_1+7,700=9,000[/tex]

[tex]13x_1+7,700-7,700=9,000-7,700[/tex]

[tex]13x_1=1,300[/tex]

[tex]\frac{13x_1}{13}=\frac{1,300}{13}[/tex]

[tex]x_1=100[/tex]

Therefore, the company sold 100 widgets.

Substitute [tex]x_1=100[/tex] in equation (1):

[tex]100+x_2=350[/tex]

[tex]100-100+x_2=350-100[/tex]

[tex]x_2=250[/tex]

Therefore, the company sold 250 gizmos.

Answer:

  x1 + x2 = 350

Step-by-step explanation:

The total number of items sold is the sum of the number of widgets sold and the number of gizmos sold:

  (widgets sold) + (gizmos sold) = total items sold

We are supposed to represent widgets sold using x1, and gizmos sold using x2. The total number of items sold is given in the problem statement as 350. Substituting these values into the above equation, we get the equation you're looking for:

  x1 + x2 = 350

Answer:

5x + 2y + z

Step-by-step explanation:

The perimeter of a polygon is the sum of the lengths of all the sides of the polygon. This polygons has 8 sides. Their lengths are:

x, x, x, x, x, y, y, z

The perimeter of the polygon is the sum of the lengths shown above.

perimeter = x + x + x + x + x + y + y + z

The expression above can be simplified by combining like terms.

perimeter = 5x + 2y + z

(3x²+1)(4x-3) = 12x^3-9x²+4x-3.....answer 1

Step-by-step explanation:

[tex](x^2+5x+4)\div(x+2)^2=(x^2+4x+4+x)\div(x+2)^2\\\\=(x^2+2(x)(2)+2^2+x)\div(x+2)^2\qquad\text{use}\ (a+b)^2=a^2+2ab+b^2\\\\=\bigg((x+2)^2+x\bigg)\div(x+2)^2=\dfrac{(x+2)^2+x}{(x+2)^2}=\dfrac{(x+2)^2}{(x+2)^2}+\dfrac{x}{(x+2)^2}\\\\=1+\dfrac{x}{(x+2)^2}[/tex]

For this case we must solve the following inequality:

[tex]x-2> 2x + 12[/tex]

We follow the steps below:

We subtract 2x on both sides of the inequality:

[tex]x-2-2x> 2x + 12-2x\\-x-2> 12[/tex]

We add 2 to both sides of the inequality:

[tex]-x> 14[/tex]

We multiply by -1 on both sides of the inequality, taking into account that the sense of inequality changes:

[tex]x <14[/tex]

Answer:

[tex]x <14[/tex]

Answer:

The guys above is wrong because it should be x < -14 because you have to balance out both sides of the equation, you can't just do something to one side of the equation and not do it to the other.

Answer:

(20+2)(10+9)

Step-by-step explanation:

The area model is written as (a+b)(c+d). To write a multiplication problem into an area model, split it into numbers which add to it. Multiples of 10 are most commonly used.

For example 22*19 becomes (20+2)(10+9).

Any number raised to the power of 0 equals 1.

(-481)^0 = 1

Answer:

1

Step-by-step explanation:

All numbers to the power of 0 is 1 with this reason:

x³

x² = x³/x

x¹ = x²/x

x⁰ = x/x

All numbers divided by itself is 1.

Answer:

[tex]f(x)=3(x+2)(x-2)(x-\frac{5}{3})[/tex]

Step-by-step explanation:

The rational roots theorem tells you that given a polynomial function with integer or whole number coefficients, a list of possible solutions can be found by listing the factors of the constant, or last term, over the factors of the coefficient of the leading term.

In your case, for the polynomial [tex]f(x)=3x^3-5x^2-12x+20:[/tex]

So, possible rational roots can be among:

[tex]\pm1,\pm2,\pm4,\pm5,\pm10,\pm20,\pm\dfrac{1}{3},\pm\dfrac{2}{3},\pm\dfrac{4}{3},\pm\dfrac{5}{3},\pm\dfrac{10}{3},\pm\dfrac{20}{3}.[/tex]

Note that

[tex]f(-2)=3\cdot (-2)^3-5\cdot (-2)^2-12\cdot (-2)+20=-24-20+24+20=0.[/tex]

This means that [tex]x=-2[/tex] is a root of the polynomial and [tex]x-(-2)=x+2[/tex] is the factor. Also

[tex]f(2)=3\cdot 2^3-5\cdot 2^2-12\cdot 2+20=24-20-24+20=0.[/tex]

This means that [tex]x=2[/tex] is a root of the polynomial and [tex]x-2[/tex] is the factor. Also

[tex]f(\frac{5}{3})=3\cdot (\frac{5}{3})^3-5\cdot (\frac{5}{3})^2-12\cdot \frac{5}{3}+20=\frac{125}{9}-\frac{125}{9}-20+20=0.[/tex]

This means that [tex]x=\frac{5}{3}[/tex] is a root of the polynomial and [tex]x-\frac{5}{3}[/tex] is the factor.

Then

[tex]f(x)=3(x+2)(x-2)(x-\frac{5}{3}).[/tex]

Answer:

{4, - 1}

Step-by-step explanation:

Given

2y² - 6y - 8 = 0 ← in standard form

with a = 2, b = - 6, c = - 8

Using the quadratic formula to solve for y

y = ( - (- 6) ± [tex]\sqrt{(-6)^2-(4(2)(-8)}[/tex] ) / (2 × 2)

  = ( 6 ± [tex]\sqrt{36+64}[/tex] ) / 4

  = ( 6 ± [tex]\sqrt{100}[/tex] ) / 4

  = ( 6 ± 10 ) / 4

x = [tex]\frac{6+10}{4}[/tex] = [tex]\frac{16}{4}[/tex] = 4

OR

x = [tex]\frac{6-10}{4}[/tex] = [tex]\frac{-4}{4}[/tex] = - 1
