By Sine Rule,
x/sin30° = 8/sin90°
x/0.5 = 8/1
So x = 4.
4n - 9 + 3n + 5 + n = 68
combine like terms
8n - 4 = 68
addition property of equations
8n = 72
division property of equality
n = 9
SIDES:
n = 9
3n + 5 = 32
[ 3(9) + 5 = 32 ]
4n - 9 = 27
[ 4(9) - 9 = 27 ]
Answer:
45 degrees
Step-by-step explanation:
We have been given that in 1983, the per capita consumption was 39.7 pounds, and in 1989 it was 47 pounds.
Let us assume t=0 corresponds to year 1980.
Hence, we can express the given information as ordered pairs as (3,39.7) and (9,47).
We can to find a linear function passing through these points. Let us first find slope of the linear function:

We can write the required linear function as:

Upon simplifying this, we get:

In order to find per capita consumption in 1995, we need to substitute t=15 in this function.

Therefore, we would expect the per capita consumption of chicken in 1995 to be 54.3.
