Answer:

Step-by-step explanation:
Therefore,
should be your final answer.
Saw A = 150 planks/30 seconds = 5 planks per second
Saw B = 130 planks/ 13 seconds = 10 planks per seconds
5 + 10 = 15 planks per second total
225 planks / 15 planks per second = 15 seconds
Answer: 15 seconds
Answer:
3. the answer
Step-by-step explanation:
because I know
Answer : y = -3/4x + 1
To find an equation that goes through the two points provided, you have to find the slope using those same two points.
The equation for slope is (y2-y1)-(x2-x1).
The slope is -3/4.
The y-intercept is already given to you in the point (0,1).
Just plug everything into an equation and you get y = -3/4x + 1.
It could be a deltahedron. A deltahedron has all faces being an equilateral triangle. The amount of faces can vary from 4, 6, 8, 10, 12, 14, 16 and 20.
