How does an earthquake of magnitude 7.9 compare in intensity with an earthquake of magnitude of 3.7 on the Richter scale? The l

Andre45 [30]

We are required to compare the magnitude for two earthquake intensity:
the larger intensity is 7.9
the smaller intensity is 3.7
thus the ratio of the intensity will be:
(larger intensity)/(smaller intensity)
=7.9/3.7
=2.135
~2
Thus we conclude that:
The larger earthquake's intensity was 2 times as great as the smaller earthquake's intensity.

Please answer the question from the attachment.

xenn [34]

Change it into improper fraction to make it easier or just solve it as is.
= $3\frac{5}{8}$ - $2\frac{7}{8}$
= $\frac{29}{8}$ - $\frac{23}{8}$
= $\frac{6}{8}$ = $\frac{3}{4}$
OR
= $3 \frac{5}{8}$ - $2 \frac{7}{8}$
divide it to two parts:
3-2=1 and $\frac{5}{8}$ - $\frac{7}{8}$ = $\frac{-2}{8}$
$1\frac{-2}{8}$ ⇒(1×8-2=6)
= $\frac{6}{8}$ = $\frac{3}{4}$

What is the value of x in the figure? <br><br><br> x= ?

Otrada [13]

X = 68

Since the angle opposite of it is a right angle, we know that 22 + x has to equal 90 also.

So just take 90 - 22 = 68 degrees

The number of students who chose lunch was 5 more than the number of students who chose breakfast. Write a system of linear equa

Papessa [141]

Answer:

The system of linear equations are $y=5+x$ and $x+y=25$

Step-by-step explanation:

Given : The number of students who chose lunch was 5 more than the number of students who chose breakfast. Let x represent the number of students who chose breakfast and y represent the number of students who chose lunch.

(50 students picked, 25 picked dinner the rest picked lunch and breakfast)

To find : Write a system of linear equations that represents the numbers of students who chose breakfast and lunch ?

Solution :

The number of students who chose breakfast be 'x'

The number of students who chose lunch be 'y'.

The number of students who chose lunch was 5 more than the number of students who chose breakfast.

i.e. $y=5+x$

Now, Total student were 50 and 25 picked dinner the rest picked lunch and breakfast i.e. 25.

So, $x+y=25$

Therefore, the system of linear equations are $y=5+x$ and $x+y=25$
