What is the volume and total surface area?? PLEASE HELP

1 answer:

Illusion [34]3 years ago

8 0

Step-by-step explanation:

the volume would be inside of the spear so i could be wrong but you would do 10 multiplied by 21 and you get 210. IF you did base and height the base would be 10ft and the height would be 21ft then you just do base times height and that gets you 210 . i could be wrong though

2| x-3| - 5 = 7 Helpp

klasskru [66]

Answer:

x = {9, -3}

Step-by-step explanation:

2| x-3| - 5 = 7
2| x-3| = 12
| x-3| = 6
x - 3 = ± 6
⇒ x= 3+ 6= 9
⇒ x= 3 - 6= -3

Or it can be shown as:

x= {9, -3}

77 yd<br> 36 yd<br> What is the length of the hypotenuse?<br> C =<br> yards

Elden [556K]

Answer:

c = 85 yd

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

c² = 77² + 36² = 5929 + 1296 = 7225 ( take square root of both sides )

c = $\sqrt{7225}$ = 85
