B) 10⁻⁸ is 100 million times smaller than 10.

C) The value 7.4 x 10⁻⁸ is 527 times smaller than 0.000039.

We use scientific notation in writing large or small numbers by multiplying a number between 1 and 10 by a power of 10.

Answer: -1

Step-by-step explanation:

    We will find the answer to this question by isolating the x variable.

    Given:

2(3x – 1) ≥ 4x – 6

    Distribute the 2 with multiplication:

6x – 2 ≥ 4x – 6

    Add 2 to both sides of the equation, and subtract 4x from both sides of the equation:

2x ≥ – 4

Answer:

The greatest common factor of 10m2 and 4m4 is:

2

Step-by-step explanation:

The measure of angle FGE from the given figure is 28° when  the measure of arc CDE = 118° and the measure of arc EF = 62°.

The measure of an arc is equal to the measure of its corresponding central angle.

From the given figure, the measure of arc CDE = 118° = corresponding central angle (∠CAE)

So, ∠CAE = 118°

From the given figure, the measure of arc FE = 62° = corresponding central angle (∠FAE)

So, ∠FAE = 62°

As we know the radius of a circle is perpendicular to the tangent.

That is, AE ⊥ EG

So, ∠AEG = 90°

Now, ∠AGE+∠AEG+∠GAE = 180° (The sum of interior angles of a triangle is equal to 180°)

∠AGE + 90° + 62° = 180°

⇒ ∠AGE + 152° = 180°

⇒ ∠AGE = 28°

So, ∠AGE = ∠FGE = 28°

Therefore, the measure of angle FGE from the given figure is 28°.

Answer:

Answer: 0.7

Step-by-step explanation:

Let the number of white cows be x

Thus, the number of brown cows be (x+12)

Hence,

x+(x+12)=60

x+x+12=60

2x+12=60

2x+12-12=60-12

2x=48

Divide both parts of the equation by 2:

x=24 white cows

x+12=36 brown cows

The number of white cows are less than one year old:

[tex]\displaystyle\\\frac{3}{4}(24)=\\\\\frac{3(24)}{4}=\\\\ 3*6=\\\\ 18\ white\ cows[/tex]

The number of brown cows are less than one year old:

A relation is proportional if the "output" is zero when the "input" is zero, and the rate of change is constant. The graph of a proportional relationship is a straight line through the origin.

Any relation involving a base cost or flat fee will not be a proportional relationship. The graph of such a relation may be a straight line, but it will not go through the origin.

Answer:

Mei is correct because -9 is to the left of -3 on the number line.

Step-by-step explanation:

This is because -9 is LESS than -3, when you add or subtract using negative numbers, such as 7-9, you get -2. However when you subtract 7-13, you get -6. Because you subtracted a greater number from 7, your answer is -6 is LESS than -2. This is the same with inequalities, greater negative numbers will always be smaller and smaller negative numbers will always be greater.

Answer:

The unit rate for miles per gallons is 35.6 miles per gallon used by him.  

Step-by-step explanation:

In the given condition he drove 44 and 1/2 miles and used a total of 1 and 1/4 gallons of gasoline.

Now, we have to calculate the number of miles he travelled in each gallon.

So, 44 and 1/2 miles can be written as 44.5 miles.

And 1-1/4 gallons can be written as 1.25 gallons.

Now, we need to form an equation from the above condition;

=> 44.5 = 1.25

=> x = 1 (here, x is the number of miles per gallon)

Now, after cross multiplying the equation;

=> 44.5 × 1 = 1.25 × x

=> 44.5 = 1.25 x

=> 44.5 / 1.25  = x

=> x = 35.6 miles per gallon

Therefore, the unit rate for miles per gallons is 35.6 miles per gallon used by him.

Given that the sum of the interior angle of a triangle is 180 degrees, the numerical value of x is 4.

In a polygon, an interior angle is one formed by two consecutive sides: that is, the vertex of an interior angle coincides with the vertex of the polygon.

A triangle is a polygon with three edges and three vertices.The sum of interior angle of a polygon is expressed as;

S = ( n - 2) × 180°

Where n is number of side.

Since a triangle has 3 sides, the sum of interior angle of a triangle will be;

( 3 - 2) × 180° = 1 × 180° = 180°

From the diagram;

Since the sum of interior angle of a triangle is:

180° .35° + 60° + ( 22x - 3 )° = 180°

Solve for x

35 + 60 + 22x - 3 = 180

95 + 22x - 3 = 180

92 + 22x = 180

22x = 180 - 92

22x = 88x = 88/22x = 4

The numerical value of x is 4.

Rewrite the above equation properly

So, we have

1 mole = 6.02 × 10^23 particles

Multiply both sides by 12

So, we have

12 x 1 mole = 12 x 6.02 × 10^23 particles

Use Fleury's Algorithm to find an Euler path through the graph using this new edge by listing the vertices in the order visited is;  G-H-L-K-G-J-I-G

A quick examination of the given graph tells us that two of the seven vertices (G, I) have an odd number of edges while the other five (F, H, J, K, L) have an even number. Since every vertex must have an even number of attached edges for us to possibly construct an Eulerian circuit, our first step is necessary to add an edge connecting G to I.

A somewhat easy way to now construct an Eulerian circuit would be to take our original graph (i.e. without the G-I edge) and find an Eulerian path from D to H, then end by taking our added D-H edge back to D.

The way to find Fleury's Algorithm, is that;

1) Start with classifying the vertices of the given graph as odd and even. If there are 0 or 2 odd vertices, then continue with the algorithm.

2) Begin with any one of the odd vertices, if they exist, otherwise arbitrarily choose a vertex as the starting point.

3) Travel every edge exactly once such that the bridges in the graph are travelled at the end.

4) Stop when all the edges are travelled.
