L think the answer is 2*-17*+30=-1,020
Answer:
V = 621.4 mm^3
Step-by-step explanation:
The volume of this pyramid is V = (1/3)(base area)(height). We must calculate the height from the info given. Draw in a vertical line to represent the height. Imagine a triangle with hypotenuse 12.8 mm (given) and shorter leg (13 mm)/2, or 6.5 mm.
The Pythagorean Theorem applies here: h^2 + (6.5 mm)^2 = (12.8 mm)^2. We get: h^2 + 42.25 = 163.84, or h^2 = 121.59, or h = √121.59, or
h = 11.03 mm.
Then, as before, the volume of this prism is V = (1/3)(base area)(height), or with specific numerical values V = (1/3)(13 mm)^2(11.03 m), or
V = 621.4 mm^3
Answer:
2,099,000
Step-by-step explanation:
So the problem is
4x-5=7+4y
solve for y
easy
minus 7 from both sides
4x-5-7=7-7+4y
4x-12=0+4y
4x-12=4y
divide both sides by 4
x-3=y
y=x-3
You need to find the unit rate. if you have 64/8, 8 divided by 8 = 1. 64 divided by 8 is 8
