Volume of the cube is 1000 cm³
Step-by-step explanation:
- Step 1: Find the volume of the cube.
Side of the cube = 10 cm
⇒ Volume of the cube =(side)³ = 10³ = 1000 cm³
Answer:
It should be the top left graph where there is point (1,1) and (-1, -1) y = 1/x
Step-by-step explanation:
from the original graph, I see:
f(x) = 2/x because f(2) = 1 = 2/2
f(1/4)= 2/(1/4) = 2
...
so then f(2x) compresses f(x) horizontally by a factor of 2
so f(2x) = 2/(2x) = 1/x
Answer:
4 hours
Step-by-step explanation:
For three visits, the electrician earned $40 × 3 = $120 in "per-visit" charges. For working x hours, he earned 20x in "per-hour" charges. The total of these came to 50x:
120 +20x = 50x
120 = 30x . . . . . . . . subtract 20x
4 = x . . . . . . . . . . . . . divide by 30
The electrician worked 4 hours that day.
Bulletin boards can be in all shapes and sizes. There is no correct or incorrect answer to this problem.
Answer:
No
Step-by-step explanation:
Given
Quadrilateral A: 2,3,5 and 6
Quadrilateral B: 4,5, 8 and 10
Required
Determine if one is a scale of another
To do that, we have to divide the corresponding lengths to give ratio.
Considering Side of A = 2 and Side of B = 4



Considering Side of A = 3 and Side of B = 5



There's no need to check further, since the two ratios calculated so far do not have the same value;
<em>Hence, one quadrilateral is not a scale of the other</em>
