X-0.9 = 4.5
+0.9 +0.9
x = 5.4
( to get rid of the -0.9 beside the x, u have to do the opposite operation on both sides. if its -0.9, u have to add 0.9 on both sides)
not sure about the first one.
Answer:
(1436.8cm³) let me know if that helps
Step-by-step explanation:
-so if the diameter is a straight line and it's 15 cm
-The formula for the sphere it would be v=4/3πr³
-The radius is going to be r=7cm
-v = 4/3 π (7cm)³
-so you would type in 4/3 x 3.14 x 7 ³ =1,436
- 3.14 or π
- you would round it to the nearest 10th (1436.8cm³)

You are given
the surface area of the cube which is 96cm2. You are asked to find the length
of one side and its volume. Note that the surface area of the cube is equal to
6 times the square root of s (the side of the cube) and the volume is the cube
root of s. So,
SA = 6*s^2
96cm2 = 6*s^2
s^2 = 16cm
<u>s = 4cm,
this is the length of one side.</u>
V = s^3
V = (4)^3
<u>V = 64cm3,
this is the volume of the cube.</u>
Answer:
Check below
Step-by-step explanation:
Hi there!
1)Assuming that we're dealing with a Three Dimensional plane, with their three axes xyz.
To construct a line <em>m</em> in which every y-coordinate is y= 
, to have the y -coordinate will be constant on 
.
Similarly, the same for the line n with its z-coordinate fixed on 
2) Since we're on a 3D plane with not two but three axes x, y, and z, the line in 2D (just x and y view) will be seen as planes. Check the second picture, please.
