(1a) What is the highest price that a book could be?

Answer:

  4

Step-by-step explanation:

Consider the arcs PQ and P'Q. When turns are made without slipping, these have the same measure. The length of arc PQ is ...

  PQ = CP·θ

The length of arc P'Q is ...

  P'Q = O₂Q·(∠PO₂Q)

Segment O₂A is parallel to CP, so angle AO₂Q is θ. Then ∠PO₂Q = θ+α, where α is the angle by which P' has rotated counterclockwise from A.

We are given that ...

  CP = 5, O₂Q = 1

Using the above relations, we can write ...

  5θ = 1(θ+α)

  α = 4θ

That is, for every full turn θ = 2π, the smaller circle makes turns totalling 4(2π) = 8π, or 4 full turns.

The small circle makes 4 revolutions to arrive at its starting point.

Answer:

y<-12

Step-by-step explanation:

-3y>36 divide both sides of the inequality by -3 and flip the inequality sign

-3y÷(-3)<36÷(-3) any expression divided by itself equals 1

y<36÷(-3) which equals to y<-12

Answer:

Option B

Step-by-step explanation:

By plotting the points given in the table,

All points lie below the dark red line.

Let the equation of the line is,

y - y' = m(x - x')

Here, m = Slope of the line

(x', y') is a point lying on the given line.

Slope of the line passing through two points (-1, 3) and (0, 1) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{3-1}{-1-0}[/tex]

m = -2

Therefore, equation of the line passing through (0, 1),

y - 1 = -2(x - 0)

y = -2x + 1

Since all the points given in the table lie below the dark red line so the solution are will be,

y ≤ -2x + 1

Option B will be the correct option.

Answer:

x = 3

Step-by-step explanation:

5(5 + 19) = 6(6 + 4x + 2)

5(24) = 36 + 24x + 12

120 = 48 + 24x

72 = 24x

x = 3

Answer:

y = 5

Step-by-step explanation:

Equation:

m<DGF = m<DGE + m<EGF

Given:

m<DGF = 12y - 5

m<DGE = 5y + 6

m<EGF = 24

Work:

m<DGF = m<DGE + m<EGF

12y - 5 = 5y + 6 + 24

12y - 5 = 5y + 30

12y - 5y = 30 + 5

7y = 35

y = 5

Answer:

1) m<DBE= 140

2)m<EBD= 30

Step-by-step explanation:

1) 5x-60= x+20

4x= 80

x= 20

plug in the x into the equation: (x+20)---> (20+20)=40

180-40= 140

2) 4x-2+20x-10= 180

24x= 192

x=8

plug in the x into the equation: (4x-2)----> 4(8)-2----> 32-2= 30

Answer:

Carole's situation :   2x + 11y = 196

Michele's situation:  10x + 11y = 276

Step-by-step explanation:

If x = cost of 1 cupcake, then 2x = cost of 2 cupcakes and 10x = cost of 10 cupcakes, et.

If y = cost of 1 sugar cookie, then 11y = cost of 11 sugar cookies.

Carole's situation :   2x + 11y = 196

Michele's situation:  10x + 11y = 276

Answer:

y + 4 = 3(x + 5)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 3 and (a, b) = (- 5, - 4) , then

y - (- 4) = 3(x - (- 5) ) , that is

y + 4 = 3(x + 5)

Hi there! The point-slope is shown in the picture.

Both x1 and y1 are the ordered pairs or coordinate points. Not to be confused with the x and y, they are just for to form an equation of a line.

As we know, m is defined as slope.

What we have now are:

Substitute the value of the point and slope in the equation.

[tex] \large{y - ( - 4) = 3(x - ( - 5))} \\ \large{y + 4 = 3(x + 5)}[/tex]

Answer

Answer:

66.7%

Step-by-step explanation:

The number of seedlings planted is 6, while the number of seedlings that survived the winter is 4. Therefore the percentage of seedlings that survived can be gotten using the formula:

Percentage of seedlings survived = (survived seedlings / total seedlings planted) * 100%

Therefore substituting values gives:

Percentage of seedlings survived = (4 / 6) * 100% = 66.7%

Answer:

Darnell can run 1100 yards in 6 minutes

Step-by-step explanation:

There are 2 ways you can solve this

Method 1: You would have to divide 550 by 3 which you would get about 183, (the exact answer is very long so I recommend using a calculator). Then you multiply that by 6 to get 1100.

Method 2: This one would probably be easier. Since 3 x 2 is 6 then you can multiply 550 x 2 to get 1100.

I hope this helps!

Answer:

1100 yards

Step-by-step explanation:

Write it as an equation

550/3 = x/6

Cross multiply :

550 * 6 = 3x

3300 = 3x

x = 1100

Answer:

64 ft²

Step-by-step explanation:

A prism is a three dimensional shape with two identical shapes facing each other known as bases. A right prism is a three dimensional solid with a polygon as its base and vertical sides which are perpendicular to the base.

Given that the first sandbox is a right prism a square base, hence this is a square prism (that is a cube).

Since the side length of the square base is 8 ft, hence the area of the base of the first sandbox is:

Area of the base = length * length = 8 ft * 8 ft = 64 ft²
