The ratio of two numbers is 2/3, and their sum is 535. One of the numbers is:

1 answer:

6 0

The answer is D

Step-by-step:

X is one of these two numbers and the other is 2/3X
Sum=X+2/3x=5/3x=535
So X=535*3/5=321

What is the area of a sheet of binder paper? (Binder paper is 8 1/2 inches by 11 inches.) 88 inches 88 1/2 in2 93 1/2 in2 94 in2

hichkok12 [17]

Answer:

93 1/2 in^2.

Step-by-step explanation:

The Area = 8 1/2 * 11

= 17/ 2* 11

= 187/2

= 93 1/2 in^2.

part b is: if the energy release of one earthquake is 10,000 times that of another, how much larger is the Richter scale reading

kotegsom [21]

You could use the information from part A to get B. I'm not sure if you want A or not, so I'll do it as well.

Eo = 10^4.4 Joules

E = 2 * 10^15

Formula

M = (2/3) log (E/Eo)

M = 2/3 * log (2 * 10^15/10^(4.4) )

M = 2/3 * log( 7.9621* 10^10)

M = 2/3 * 10.901

M = 7.26735 on the Richter scale. That is a huge amount of energy.

Part B

Suppose that you use Eo and your base. Eo is 10^4.4

Now the new earthquake is E = 10000 * Eo

So what you get now is M = (2/3)* Log(10000 * Eo / Eo )

The Eo's cancel out.

M = 2/3 * log(10000)

M = 2/3 of 4

M = 8/3

M = 2.6667 difference in the Richter Scale Reading. It is still an awful lot of energy.

What this tells you is that if the original reading was (say) 6 then the 10000 times bigger reading would 8.266667

Answer: M = 2.6667

Carlos performed a transformation on trapezoid EFGH to create E′F′G′H′, as shown in the figure below:

Nataliya [291]

Answer:

90° clockwise rotation or 270° anticlockwise rotation

Step-by-step explanation:

(x,y)=(y,-x)

E(-6,-4)=E'(-4,6)

F(-4,-4)=F'(-4,4)

G(-2,-6)=G'(-6,2)

H(-7,-7)=H'(-7,7)

Therefore, E prime is (-4,6), F prime is (-4,4), G prime is (-6,2) and H prime is (-7,7).
