Answer:
Step-by-step explanation:
these are two different questions .
first i solve first
position of submarine= -250/3 meters below see level
height descended=120 % of 250/3=120/100 ×(250/3)=300,00/300=100 m
new location=-250/3+(-100)=-650/3 below see level.
2nd question
position of submarine=-250 2/3=-752/3 m below see level
height descended=120 5/8=965/8 m =-965/8 m below see level
new positin=-752/3+(-965/8)=-(6016+2895)/24=-8911/24=-371 7/24m below sesa level.
Mean is another word for average add all the values and divide by the numbers in the set
Surface area of sphere is 
Step-by-step explanation:
We need to find the surface area of the sphere while we are given volume of sphere = 972π
The formula used to find surface area is:

We need to find radius of sphere
We are given Volume = 972π, using this volume we can find radius of sphere
The formula used to find volume is:

Putting values and finding r


Taking cube root on both sides
![\sqrt[3]{r^3}=\sqrt[3]{729}\\ r=9](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Br%5E3%7D%3D%5Csqrt%5B3%5D%7B729%7D%5C%5C%20r%3D9)
So, Radius of sphere r=9
Now finding surface area:




So, surface area of sphere is

Answer:
m<1: 51
m<2: 61
m<3: 29
Step-by-step explanation:
m<1 = 51, because to find the 3rd angle, you need to add the other two angles and then subtract 180 from that answer.
61 + 68 = 129
180 - 129 = 51
m<2 = 61, because it's a vertical angle, meaning that the angle that's opposite to it exactly, is the same. So since the angle opposite to m<2 is 61, that's what the answer would be.
m<3 = 29, because all you need to do is add 90 and 61, and then subtract 180 by the answer. I got 90 as one of the angle measurements because there's a right triangle, meaning it's 90. Then since we already know what angle 2 is (61) then all you need to do is add:
90 + 61 = 151
Then subtract:
180 - 151 = 29
Answer:
See below
Step-by-step explanation:
The first two questions are slope = 0
a horizontal line has zero slope
slope = rise/run = 0 / run = 0
Greatest y value is + 4 from x = 3 to 4
the least y value is -3 fro x = -4 to -3
