Answer:
70
Step-by-step explanation:
another angle is 150 - 130 degree
so look at the triangle
we know x + 90 + 20 = 180 degree
so x = 70 degree
Answer:
36
Step-by-step explanation:
Since f(x) varies directly with x, f(x) can be expressed alternatively as \[f(x) = k * x\] where k is a constant value.
Given that f(x) is 72 when the value of x is 6.
This implies, \[72 = k * 6\]
Simplifying and rearranging the equation to find the value of k:
k = \frac{72}{6}
Hence k = 12
Or, \[f(x) = 12 * x\]
When x = 3, \[f(x) = 12 *3 \]
Or in other words, the value of f(x) when x=3 is 36
Answer:
the total price would be 9.81
Step-by-step explanation:
9% of 9 = 0.81
