Answer:
Step-by-step explanation:
Let x represent the number of stamps from Europe.
Let y represent the number of stamps from Africa.
Let z represent the number of stamps from Asia.
She has 47 stamps in all. This means that
x + y + z = 47 - - - - - - - - - - - 1
The number of African stamps is 2 times the number of Asian stamps. This means that
y = 2z
She has 20 stamps from Europe. Therefore, substituting x = 20 and y = 2z into equation 1, it becomes
20 + 2z + z = 47
3z = 47 - 20 = 27
z = 27/3 = 9
y = 2z = 2 × 9
y = 18
She has 20 stamps from Europe, 18 stamps from Africa and 9 stamps Asia.
We know that
[volume of a cylinder]=pi*r²*h------> h=volume/[pi*r²]
diameter=4 in
r=4/2---> r=2 in
Volume =125 in³
h=125/[pi*2²]-----> h=9.95 in
the answer is
the height of the can is 9.95 in
6 tps baking powder. For every 3, there is two. 3 multiplied by 2 is 6.
Answer:
We know area of a square = side× side
Let the length of each side of the square be s
s×s= 121 sq ft
s²= 121 sq.ft
s=√121
s= 11 ft
11 ft long and wide
