Answer:

29/48

Step-by-step explanation:

Total number of spins: 8 + 11 + 17 + 12 = 48

Total number of spins greater than 2: 17 + 12 = 29

p(greater than 2) = 29/48

Answer:

A

Step-by-step explanation:

To answer this, look at one specific point for example, A. It is at the point (3,6). In order for this point to get to where it was moved to, you must rotate it counterclockwise () 90 degrees. Do this by changing the initial point from (x,y) to (-y,x). This is located at (-6,3). Then you can see that it was translated 2 units up from there.

I hope this helped.

Rotate 90 degrees counterclockwise then translate 2 units up.

Option B is correct.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

In the figure ABCD, is transformed to figure A'B'C'D'.

It is Transformed from Quadrant 1 to quadrant 2

So, the point (x,y) is (-y,x).

It is then moved up by 2 units.

Now, the figure is rotated counterclockwise and translated up by 2 units.

The parallelogram ABCD formed by vertices A(x, y) = (0, 0), B(x, y) = (3, 6) and C(x, y) = (11, 2) has a point D with the following coordinates: D(x, y) = (14, 8).

In this question we know only three vertices of the parallelogram. To determine the missing point we must understand the properties of parallelograms. Vectorially speaking, we can find the missing vertex by using the following property:

[tex]\overrightarrow{AB} = \overrightarrow {CD}[/tex]

[tex]\vec B - \vec A = \vec D - \vec C[/tex]

[tex]\vec D = \vec C + (\vec B - \vec A)[/tex]

D(x, y) = (11, 2) + [(3, 6) - (0, 0)]

D(x, y) = (11, 2) + (3, 6)

D(x, y) = (14, 8)

Answer:

301.224 g

Step-by-step explanation:

Let's divide in the ratio 21:4 the volume of the medal (35cm^3)

copper = (21/25)(35cm^3) = 29.4cm^3

tin = (35 - 29.4)cm^3 = 5.6cm^3

FOR THE COPPER

8.84 : 1 = X : 29.4

X = 259.896(g)

FOR THE TIN

7.38 : 1 = X : 5.6

X = 41.328(g)

(259.896 + 41.328)g = 301.224 g

Hey there!

x = -1 or x = -8 ✅

To solve this equation, you have to use the zero product property.

↳ Ifa product of factors is zero, then at least one of its factors is zero.

Which means that either x + 1 = 0 or x + 8 = 0

⇒ x + 1 = 0

Subtract 1 from both sides :

⇒ x + 1 - 1 = 0 - 1

⇒ x = -1

OR

⇒x + 8 = 0

Subtract 8 from both sides :

⇒x + 8 - 8 = 0 - 8

⇒x = -8

Therefore, x = -1 or x = -8.

Area=18ft^3 Surface Area=44ft^2

Step-by-step explanation:

The formula for area of a rectangular prism is A=lwh. So you just plus that in

Answer:

Volume = 18 cubic feet
Surface Area = 44 square feet
Double width = Double the space

Step-by-step explanation:

Please see attached explanations.

Surface area is the area (one side multiplied by another) of every side of the storage box, added together.
I have labeled each unique pair of sides as a, b, and c. That is top and bottom, left and right side, and front and back side.

Volume is the length multiplied by the width multiplied by the height.

By doubling the width, you are doubling the size of the box in that given direction. You can prove this mathematically by making the width twice of what it was and finding volume again.

Step-by-step explanation:

you first multiply both sides by 4

hence,

40 > 5u > 30

then you just divide by 5 to get

8 > u > 6

The area of polygons formulas to V=2.56m^2

We have to determine,

The volume of the pyramid.

The volume of a pyramid is found using the formula,

V = (1/3) Bh

where 'B' is the base area and 'h' is the height of the pyramid.

hight =2.4m

base=1.4+1.8

base=3.2m

V = (1/3) (3.2)(2.4)

V=2.56m^2

As we know the base of a pyramid is any polygon,

we can apply the area of polygons formulas to find 'B.
