Answer:
-15/7
Step-by-step explanation:
Let B(x1, y1) be on vertical (y-axis) then B = (0, 15) and
A(x2, y2) be on horizontal (x-axis) then A = (7, 0).
Now, slope = (y2 - y1)/(x2 - x1)
then slope = (0 - 15)/(7 - 0)
=> slope = (-15)/7
slope of the budget = -15/7
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>
