Assuming that "piece" refers to the plywood, not the fabric. Very poorly stated
question. Rectangle 1:12 3/4 square inches = 12.75 sq in; 2 1/8 in = 2.125 in;
12.75 sq in / 2.125 in = 6 in.
Rectangle 2: 2 1/10 in = 2.1 in; 12.75 sq in / 2.1 in = 6.07143..., rounded to 6.1 in; OR 12 3/4 sq in = 51/4 sq in; 2 1/10 in = 21/10 in; 51/4 sq in / 21/10 in = 51/4 * 10/21 = 510/54 in = 85/14 in.
If you meant that 1 ball can complete a full rotation in 120 mins then to have a 180 min rotation you need 1.5 balls.
Answer:
3 1/4 + 2 1/3 = 67 / 12 = 57 1/2
Step-by-step explanation:
Conversion a mixed number to a improper fraction: 3 1/4 = 3 · 4 + 1
4
= 13
4
Conversion a mixed number to a improper fraction: 2 1/3 = 2 · 3 + 1
3
= 7
3
Add: 13
4
+ 7
3
= 13 · 3
4 · 3
+ 7 · 4
3 · 4
= 39
12
+ 28
12
= 39 + 28
12
= 67

Answer:
s = 2t
Step-by-step explanation:
At the end of a snow storm, Audrey saw there was a lot of snow on her front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 10 inches of snow on the lawn when the storm ended and then it started melting at a rate of 2 inches per hour. Write an equation for S, in terms of t, representing the depth of snow on Audreys lawn, in inches, t hours after the snow stopped falling.
2 inches = 1 hour
10 inches = x hour
2x = 10
x = 10/2
x = 5
Creating an equation
S ∝ t
S = kt
k = s/t
k = 2/1
k = 2
The equation for S, in terms of t, representing the depth of snow on Audreys lawn, in inches, t hours after the snow stopped falling is
S = 2t
