Answer:
-3/4
Step-by-step explanation:
Get the coordinates of the two points and use the slope formula to find the slope.
We'll call the points point A and point B.
Point A's coordinates are (-3,1) and point B's coordinates are (1,-2)
Now, plug the numbers into the slope formula
Slope formula is: y2-y1/x2-x1
-2-1/1--3
-3/4
Answer:
The volume of the steps is:
Step-by-step explanation:
Remember that the volume regularly is:
- Volume = height * width * depth.
There are many forms to solve this exercise, but I'll show you two:
1. Imagine that aren't steps but a big solid, then its volume would be:
- Volume of big solid = 60 cm * 60 cm * 120 cm
- Volume of big solid = 432000 cm3
Now you can subtract the volume of a small solid with measures 30 cm * 30 cm * 120 cm (<em>where is the blank for the step</em>):
- Volume of a small solid = 30 cm * 30 cm * 120 cm
- Volume of a small solid = 108000 cm3
Now you subtract:
- Volume of the building steps = 432000 cm3 - 108000 cm3
- <u>Volume of the building steps = 324000 cm3
</u>
2. The building steps are formed by three solid with volume 30 cm * 30 cm * 120 cm, so:
- Volume of the building steps = 3 (30 cm * 30 cm * 120 cm)
- <u>Volume of the building steps = 324000 cm3</u>
