Using fractions, it is found that
of a wheel still needs to be painted.
- On the first wheel, 4 of the 9 equal parts have been painted, that is,
of the wheel has been painted, hence
has not been painted.
- On the second wheel, 6 of the 10 equal parts have been painted, that is,
of the wheel has been painted, hence
has not been painted.
The total fraction that still has to be painted is:

Answer:
y = 0,5 x + (-3)
Step-by-step explanation:
We can see from the graph that when y = -3, the line crosses y axis, therefore
y = ? x + (-3)
We can also spot that when x = 6, y = 0
// now mark ? sign as a variable k and put the given x and y values into the previous expression
y = k * x - 3
0 = k * 6 - 3
k * 6 = 3
k = 3/6
k = 0,5
Answer:
421/6 degrees
Step-by-step explanation:
The acute angles of a right triangle are complementary, so

So, the acute angles measures 421/6 degrees and 119/6 degrees, and thus the larger angle is 421/6 degrees.
Answer:
12.5
Step-by-step explanation:
In order to solve, we need to add 9 to both sides of the equation:
<u>Our sum applied:</u>
b=12.5
