Answer:
380 feet below sea level.
Step-by-step explanation:
Given:
A submarine is is 250 feet below sea level.
It descended another 130 feet.
Question asked:
How many feet below sea level is the submarine now?
Solution:
A submarine is initially below the sea level = 250 feet
Another descend below the sea level = 130 feet
Now, we have to calculate the final level of submarine below the sea level and for it we will simply add initial level to the another descended depth:-
250 feet + 130 feet = 380 feet.
Therefore, submarine is now 380 feet below sea level.

you can just distribute the 4 to x+12
Answer:
58,900cm²
Step-by-step explanation:
Area of the triangle = 1/2absin thets
Area of the triangle = 1/2* i * j sin 30
Area of the triangle = 1/2 * 380 * 620 sin 30
Area of the triangle = 380 * 310 * 0.5
Area of the triangle = 380*155
Area of the triangle = 58,900cm²
hence the area of the triangle is 58,900cm²
Answer:
The slope is 4.
Step-by-step explanation:
In order to find this without graphing it you can put it in y-y/x-x form. So you subtract the y points on the top. 5-25=-20. then you subtract the x points -2-3=-5 so then you divide -20 by -5 since they are both a negative they become a positive and 20/5=4 so your slope is 4/1.
Answer:
8 hours
Step-by-step explanation:
In 2 hours, the clerical secretary can do 1/4 of the job. (The executive secretary does 3/4 of the job - or 3 times as much - in the same 2 hours.)
Since it takes the clerical secretary 2 hours to do 1/4 of the job, it will take them four times that to do it themselves. 2x4=8.
