Answer:
A, 0.13 mph.
Step-by-step explanation:
To get that, divide the cm/sec by 44.704.
6/44.704 ≈ 0.13
Answer:
x=-4/7
Step-by-step explanation:
We are given an equation as
6(x+7)+4=-8(x-5)-2
and asked to solve for x
Simplify to get
Distribute 6 over x+7 and on right side -8 over x-5
6x+42+4 = -8x+40-2
Take -8x to left side to become +8x and 46 to right side to become -46
Grouping like terms
14x = 38-46 = -8
Divide by 14
x = -8/14 = -4/7
Since this is an equation, we get a single value for x
and answer is -4/7
The complete question is:
Which statements describe the location of an earthquakes epicenter? Check all that apply.
1) it is measured by a seismograph
2) is is located using a single set of data
3) it is determined by the arrival times of s and p waves
4) it is determined by the arrival time of surface waves
5) it is located at the point where circles intersect on a map
Answer:
The answers are; 1, 3 and 5.
Step-by-step explanation:
A Seismograph is a combination of centimeters with a timing device and a recording device. It is used to locate and characterize earthquakes, and to study the Earth's internal structure.
Seismograph are not enough to locate the epicenter through Triangulization. The epicenter can also be extrapolated by using an extrapolation map that deduces the distance to epicenter using the difference in time between the arrival of the s and p waves of the earthquake.
Answer:
