To determine the ratio of the lengths of the red and blue ribbon, we just have to divide the lengths of the corresponding colored ribbon.
red / blue = 3/4 / 2/3 = 9/8
(2) The ratio of the lengths expressed as a unit rate is 9/8:1
(3) The ratio of the lengths of the blue to red ribbon is the reciprocal of the calculated value above giving us the answer of 8/9.
Answer:
157.14 cm
Step-by-step explanation:
1/2 ×22/7 ×10 ×10= 157.14 cm
Answer:
A is a function; B, C and D are not.
Step-by-step explanation:
In other words: Identify the sole function among these relationships.
A function maps any input onto exactly one output.
If a relationship maps any input onto more than one output, it is not a function.
Thus, we eliminate B, C and D. In B, for example, we have the inputs {1, 2, 3}, where the '1' has two y-values associated with it.
On the other hand, A has the domain {-1, 0, 1, 2}, and all four inputs have exactly one associated output.
Yea I don’t know sorry bye
