y = sqrt(9 * 16).
This formula is derived because of similar parts of similar right triangles.
It is called the geometric mean which you can google for right triangles that share a common side.
y = sqrt(144)
y = 12
D is the only possible answer.
=============
x = sqrt(9^2 + 12^2)
x = sqrt(81 + 144)
x = sqrt(225)
x = 15
=============
z = sqrt( (9 + 16)^2 - 15^2)
z = sqrt( 25^2 - 15^2)
z = sqrt(625 - 225)
z = sqrt(400)
z = 20
Answer D
z =
11(310+456) because if they open for 11 months and serve 310 costumers then u add that by 456 and times 310•11 and 465•11 to then add those answers together to get your total
Answer:
x = 3
Step-by-step explanation:
3x + 3 = 12
Subtract 3 from both sides
3x = 9
Divide both sides by 3
x = 3
Answer:
The volume of sphere = 268.08
Step-by-step explanation:
Below is the calculation for the volume of melon (sphere).
Given the diameter of the sphere is = 8 inches
Now find the radius by dividing the diameter by 2 = 8/2 = 4 inches
Now use the below formula to find the volume.
The volume of sphere = 
The volume of sphere = 268.08
Answer:
37/40 = 0.925 miles
Step-by-step explanation:
The total distance Melvin walked (in miles) was ...
5/8 + 3/10 = 25/40 + 12/40 = 37/40 . . . . miles
__
In decimal, the sum is ...
0.625 + 0.30 = 0.925 . . . . miles
