Answer:

Tetrahedron generally known as triangular pyramid consists of 4 triangular faces, 6 edges and 4 vertices. The base of the tetrahedron is a triangle. All the vertices have the same atom that is bonded to the central metal atom which lies in the centre of the tetrahedron. We take  as an example to see how the atoms actually bond in tetrahedron.  It is quite visible from the image that 4 O-atoms lies on all the 4 vertices and 1 Si-atom lie in the centre.

Answer:

x = 269/15

Step-by-step explanation:

(3x - 5) / 6 - (4 + x) / 7 = 5

7(3x - 5) - 6(4 + x) = 5(42)

21x - 35 - 24 - 6x = 210

15x - 59 = 210

15x = 269

x = 269/15

. How much of a 30% solution would you need to make 50 mL of a 2% solution?
Butoxors [25]

1.2mL will be needed to make 50 mL of a 2% solution

<h3>Ratio and proportions</h3>

Ratio are written in form of fractions.

If  50mL is required for a 2% solution, hence;

50% = 2mL

0.05 = 2mL

In order to determine the required mL for a 30% solution, we will have;

30% =x

0.03 = x

Find the ratios

0.5/0.3 = 2/x

Cross multiply

0.5x = 2(0.03)
0.5x = 0.6
x = 0.6/0.5

x = 1.2mL

Therefore 1.2mL will be needed to make 50 mL of a 2% solution

F(x) = 3x -6 What is 7 times f(x)​
Alina [70]

Answer:

21x - 42, see below :)

Step-by-step explanation:

Hello!

We know that f(x) is equal to 3x - 6

We want to know what 7 * f(x) is so we should first substitute f(x) for 3x - 6

7 * f(x)

7(3x-6)

We use distributive property to open the parenthesis:

7 * 3x + 7 * -6

21x - 42
