Answer:
1. Not rhombus
2. Rhombus
3. Rhombus
Step-by-step explanation:
The little lines you see represent the size. So if you see one line on all sides, its a rhombus. If you see 1 line on one side, 2 lines on two sides, and 3 on the last side, it is not a rhombus.
Look for the lines.
Answer:
X=-52
Step-by-step explanation:
-4(X+10)-6=-3(x-2)
-4x-40-6=-3x+6
-4x+3x=6+46
-x=52
X=-52
Answer:
V=1884 Cubic mm
Step-by-step explanation:
We know that the volume of the Sphere is given by the formula
Where r is the radius and h is the height of the cylinder
We are asked to determine the radius of the hollow cylinder , which will be the difference of the solid cylinder and the cylinder being carved out.
Where
is the the volume of solid cylinder with radius and height h
is the volume of the cylinder being carved out with radius and height h
where
mm ( Half of the bigger diameter )
mm ( Half of the inner diameter )
mm
Putting these values in the formula for V we get
Answer:
25
Step-by-step explanation:
So first we'll input the numbers then since we have them.
5(1) + 3(7) - 1^3
So we're going to use the order of operations here first (PEMDAS) and start with the exponent because the parenthesis I used just represent multiplication. And 1 to the power of anything is still 1. Even 1^1000000000000000000000000000.....
It's still 1.
So now we have this:
5(1) + 3(7) - 1
Now we can multiply:
5 + 21 - 1
Then, add and subtract:
26 - 1
To get:
25
