Answer:

Step-by-step explanation:

Let the yellow cubes be x

according to the question ,

blue  cubes r twice of yellow

green is 4 times of blue

 

yellow = x

blue = 2x  

green-8x            

Ratio:

Yellow : Blue : Green

  1       :   2    :     8

Probability of getting (Yellow) = 1/11

Solve for x 2/3=x/4<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B3%20%20%7D%20%20%3D%20%20%5Cfrac%7Bx%7D%7B4%20%7D%2

To solve this, you cross multiply, then divide. In this case, we multiply 4 and 2, then divide by 3.

4 x 2 = 8
8 / 3 = 2.66

So, x is 2.66

the coordinates of points a and b are (2,4) and (-2,-4) respectively. what is the slope of the line that connects the two points
solmaris [256]

we are given two points as

(2,4) and (-2,-4)

Let's assume

first point as (x1,y1)=(2,4)

so, x1=2 and y1=4

Second  point as (x2,y2)=(-2,-4)

so, x2=-2 and y2=-4

now, we can use slope formula

m=\frac{y_2-y_1}{x_2-x_1}

now, we can plug values

m=\frac{-4-4}{-2-2}

now, we can simplify it

m=2

so, slope is 2 ..................Answer

Denzel wants to work out the density of a block of wood the block of wood is in the shape of the cuboid
marishachu [46]

Answer:

Density = 1.094g/cm^3

Step-by-step explanation:

Given

Length = 17.7cm

Width = 8.3cm

Height = 13.0cm

Mass = 2090g

See attachment

Required

Determine the density of the wood

First, we calculate the volume of the wood.

Volume = Length * Width * Height

Substitute values for Length, Width and Height

Volume = 17.7cm * 8.3cm * 13.0cm

Volume = 1909.83cm^3

The density is:

Density = \frac{Mass}{Volume}

Density = \frac{2090g}{1909.83cm^3}

Density = 1.094g/cm^3<em> --- approximated</em>
