Answer: x=85
Step-by-step explanation:
you want to isolate the variable, so:
3.5x+197=494.5
Subtract 197 on both sides of the equation
3.5x=297.5
Divide both sides by 3.5 so now c is by itself on one side of the equation
x=85
Answer:
VY = 16
Step-by-step explanation:
- The median of a triangle is the segment that joins a vertex and the midpoint of the side opposite to this vertex.
- The point of intersection of the medians of a triangle, divide each median at ratio 2: 1 from the vertex.
In the given figure
∵ TUV is a triangle
∵ UZ, VX, and TW are medians
∵ UZ ∩ VX ∩ TW at point Y
∴ Y is the point of intersection of the 3 medians
→ By using the 2nd rule above
∵ The point Y divide VX at the ratio of 2: 1 from the vertex V
∴ VY: YX = 2: 1
∴ =
→ By using cross multiplication
∵ VY × 1 = YX × 2
∴ VY = 2YX
∵ YX = 8
∴ VY = 2(8)
∴ VY = 16
Answer:
20
Step-by-step explanation:
Scale factor = 8/16 = 1/2
So, 10/x = 1/2
x = 10*2
x = 20
AND operation is referred as a Boolean product:
For your info there are 5 Boolean operators:
AND, OR, NOT, NEAR, ( )
Find the volume of each and then divide the volume of the box by the volume of the cube.
Volume of box: 8 1/2 x 5 1/2 x 2 1/2 = 116 7/8 cubic inches.
Volume of cube = 1/2^3 = 1/8 cubic inches
Number of cubes: 116 7/8 / 1/8 = 935 cubes.
