A submarine is cruising at an elevation of
krek1111 [17]

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.

Find the surface area (in terms of π) of a sphere if its volume is 972 π.
Sholpan [36]

Surface area of sphere is Surface\,\,Area=324\pi

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:

Surface\,\,Area=4\pi r^2

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:

Volume=\frac{4}{3}\pi  r^3

Putting values and finding r

972\pi =\frac{4}{3}\pi  r^3

r^3=\frac{972\pi *3}{4\pi } \\r^3=729

Taking cube root on both sides

\sqrt[3]{r^3}=\sqrt[3]{729}\\ r=9

So, Radius of sphere r=9

Now finding surface area:

Surface\,\,Area=4\pi r^2

Surface\,\,Area=4\pi (9)^2

Surface\,\,Area=4\pi 81

Surface\,\,Area=324\pi

So, surface area of sphere is Surface\,\,Area=324\pi

Need help with this math problem
ladessa [460]

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
