Answer:

1050 ways

Step-by-step explanation:

Total Number of red balls = 5

Total Number of blue balls = 5

Total Number of white balls = 7

Number of red balls selected = 3

Number of blue balls selected = 4

Number of red balls selected = 5

Using the multiplication and combination relation :

nCr * nCr * nCr

Red balls = 5C3

Blue balls = 5C4

White balls = 7C5

Using calculator:

5C3 * 5C4 * 7C5 = 10 * 5 * 21

(10 * 5 * 21) = 1050 ways

Aaden is 1.75 meters tall. At 11 a.m., he measures the length of a tree's shadow to be 37.65 meters. He stands 32.9 meters away

Ratling [72]

The relationship between Aaden and the tree's height is an illustration of equivalent ratio

The height of the tree is 2.00 meters

At 11 a.m, we have:

$\mathbf{Aaden = 1.75m}$

$\mathbf{Tree\ Shadow = 37.65m}$

$\mathbf{Aaden\ Shadow = 32.9m}$

So, we make use of the following equivalent ratio

$\mathbf{Aaden : Tree = Aaden\ Shadow : Tree\ Shadow}$

This gives

$\mathbf{1.75: Tree = 32.9: 37.65}$

Express as fractions

$\mathbf{\frac{Tree}{1.75} = \frac{37.65}{32.9}}$

Multiply both sides by 1.75

$\mathbf{Tree = \frac{37.65}{32.9} \times 1.75}$

$\mathbf{Tree = 2.00}$

Hence, the height of the tree is 2.00 meters

Can someone help me 2/3+1/3x=2x what is x x must equal a fraction

trasher [3.6K]

Answer:

Step-by-step explanation:

2/3+1/3x=2x

moving all the x to one side

2/3=2x-1/3x

factoring out x

2/3=x(2-1/3)

dividing

(2/3)/(2-1/3)=x

zimovet [89]

Answer:

$20.44

Step-by-step explanation:

first solve for the whole thing

10 x 6 = 60

now to the red part

2 x 1.5 = 3

now the blue

r^2 * pi = a

2^2 * 3.14

4 * 3.14 = 12.56

now add red and blue

3 + 12.56 = 15.56

now subtract that sum from the whole

60 - 15.56 = 44.44

now do

44.44 / 10 = 4.444

now see how much it would cost for the grass

4.444 * 4.60 = 20.4424 ≈ 20.44

it would cost $20.44 to get the grass reseeded
