Using the multiplication operation, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]

Total number of ergs produced can be calculated thus :

[tex]3.9 \times 10^{33} \times 1.55 \times 10^{7} = 6.045 \times 10^{33+7} = 6.045 \times 10^{40} \: ergs [/tex]

Therefore, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]

Due to the very small measure of the diameter of the human hair, a measure of [tex]1.8 \times 10^{2} mm[/tex] would be too large, Hence, the value [tex]1.8 \times 10^{-2} mm[/tex] would be more appropriate

Answer:

-2.25=.1x

-22.5=1x

Step-by-step explanation:

Answer:

-2.5

-1.1

Step-by-step explanation:

Answer: The answer is x=4

Step-by-step explanation:

1/2x+15=5+3x

subtract 5 from both sides and now you have 1/2x+10=3x

Subtract 1/2x from both sides, leaving you with 10=2.5x

then divide 2.5 from both sides. That leaves 4=x or x=4

===========================================

Explanation:

Look at the left most sides of each figure. Dividing the smaller side over the larger leads to 7/35 = (1*7)/(5*7) = 1/5. This is the scale factor. It means the blue figure's side lengths are 1/5th of the orange figure's corresponding side lengths.

So that explains why your teacher put A = 20(1/5) = 4

Multiplying the orange side lengths by the scale factor gets you the blue side lengths.

Now focus your attention on the far right most side lengths of 25 and B

We can see that B = 25(1/5) = 5 feet.

Answer:

(13.2)(4.5)

Step-by-step explanation:

This is correct because you know that you could round one up, and one down. You know that 12*5 = 60, so you could estimate that these would have a product of 60.

Volume in both glasses = Volume (glass 1) + Volume (glass 2)

Volume (glass 1) = πr²h

r= 6.2/2 = 3.1 cm

Volume (glass 1) = πr²h = (3.1)²πh= 9.61πh

Volume (glass 2) = (1/3)πR²H

R= 6.4/2 = 3.2 cm

H = 7.3 cm

Volume (glass 2) = (1/3)πR²H= (1/3)π(3.2)² * 7.3 = (74.752/3)π

Volume in both glasses = πr²h + (1/3)πR³H

200 = 9.61πh + (74.752/3)π

9.61πh= 200 - (74.752/3)π

h= (200 - (74.752/3)π)/(9.61π) ≈ 4.03 cm

Answer is h=4.04 cm.

Answer:

h=4.04 cm.

A rotation or a reflection and a translation

Step-by-step explanation:

Ik I'm 2 years late but still.

The required angle of rotation is 180° and reflection along the diagonal of the composite figure of a rectangular flag will shift the lower left triangle to the upper right.

Given that,
To describe a sequence of translations, rotations, and reflections that take the lower left triangle to the upper right triangle.

Incongruent geometry, the shapes that are so identical. can be superimposed to themselves.

Here,
To shift the lower left triangle to the upper right,
First It must rotate by an angle of rotation of 180° around the center of the geometry, Or it must reflect to the left diagonal.

Thus, the required angle of rotation is 180°, and reflection along the diagonal of the composite figure of a rectangular flag will shift the lower left triangle to the upper right.

Answer:

The properties of the Real Number System will prove useful when working with equations, functions and formulas in Algebra, as they allow for the creation of equivalent expressions which will often aid in solving problems. In addition, they can be used to help explain or justify solutions.

Answer: Choice D

Each vertical line drawn through the graph will intersect a function in only one location.

This is another way of saying that for any input x, there is exactly one output y. If you had a vertical line cross through a curve at multiple points, then this would mean that x input produces multiple y outputs, and we won't have a function. A function must produce one output whatever the input is (assuming the input is in the domain of course).

Answer:

First, find the area for the kitchen floor: 16.5*15=247.5 squared feet

Then find the area for one tile: 0.5*0.5=0.25 squared feet

Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.

Also you can do it in this another way:

First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33

Then, do the same for the height: 15/0.5=30

Finally multyply both results: 33*30= 990 tiles.

Answer:

1/36

Step-by-step explanation:

notice the first equation is the second equation squared.

For instance, look at the numerator: a squared is a^2

Look at the denominator: a^2 squared is a^4 and so on.

So if the second equation is 1/6, then you need to square it to have it equal the second equation: (1/6)^2 = 1/36
