Answer:
5 : 6
Step-by-step explanation:
The ratio is ...
girls : boys = 20 : 24
By removing a common factor of 4 from each of these numbers, the ratio can be reduced to lowest terms:
girls : boys = 5 : 6
Answer:
The artist used 8.6 inches more of silver wire
Step-by-step explanation:
Perimeter of the square
P = 4*a
P = 4*a = 40 in
a = 10 in
Each side of the square has a length of 10 in
The diameter of the circle is equal to the length of the side of the square
Diameter = 10 in
Perimeter of the circle
P_c = 2*π*radius = π*diameter
P_c = (3.14)*10 in = 31.4 in
Inches of silver wire (square) = 40 in
Inches of copper wire (circle) = 31.4 in
40- 31.4 in = 8.6 in
I Hope This Helps.
B: 4/5
All you need to do is put the first number over the second and simplify. In this case you don't need to simplify because it is in its simplest form
Answer:
A=1/2(b×h)
divide a half by 12=6
6×4,since 4 is the height=24
