Simplify
1. 20:10 = 2:1
2. 30:36 = 5:6
3. 54: 12 = 18:7
Step-by-step explanation:
Answer for Number 1
The GCF of 20 and 10 is 10
Divide both by the GCF, 10:
20 ÷ 10 = 2
10 ÷ 10 = 1
The ratio 20 : 10 can be reduced t by dividing both terms by the GCF = 10
20 : 10 = 2 : 1
The base is a square, so the area of the square is (10 cm)² = 100 cm²
To find the area of each triangle use the formula
base • height
10 cm • 9 cm = 90 cm²
now multiply by the number of triangles
90 cm • 4 = 360 cm²
Add the area of the square:
100 cm² + 360 cm² = 460 cm²
I hope it's correct
Well you solve the equation then find out what you dealing with
Answer:
Step-by-step explanation:
The restricted value is a value that makes the denominator of a function equal to zero. Thus, solving these function results in an undefined solution.
Thus,
and 
are the restricted values for 
divided by 
Because, substituting
in
Now, substituting , we get,
Thus, results the solution undefined.
Also, substituting 
in
Thus results the solution undefined.
Hence, the restricted values are
Answer:
#3) (4/3) pi r^3
(4/3) pi 4^3
