- It's very long so I'm not giving answers but here's how i would do it:
- use Pythagoras
where c is the longest side - use sine rule
where lower cases are the sides, and capitals are their opposite angles.
e.g for 15:
a = 3, b is missing, c = 10
A is missing, B is ?, C is 90
Inequalities help us to compare two unequal expressions. The shaded potion can be made as shown below.
<h3>What are inequalities?</h3>
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
Rita does a weekly exercise program consisting of cardiovascular work and weight training. Each week, she exercises for at least 11 hours. She spends at most 7 hours on weight training. She spends at most 8 hours doing cardiovascular work.
Therefore, For the given condition let x denote the time (in hours) that Rita spends doing cardiovascular work. Let y denote the time (in hours) that she spends on weight training.
Now, the inequalities can be written as,
x + y > 11
x ≤ 7
y ≤ 8
Hence, the shaded potion can be made as shown below.

Answer:
part a- small rectangle, semi circle, big rectangle. these are the three options.
part b- cannot be solved unless height of small shaded rectangle is given
Answer:
or 
Step-by-step explanation:
The equation of a line is
, with
being the slope and
being the y-intercept.
We can see on the graph that the y-intercept, where the line crosses or touches the y-axis, is 100. So, our new equation is
.
Now we have to find the slope. Let's pick a point that's clearly on the graph. Perhaps (3, 150). And then we'll take the y-intercept point for convenience, (0, 100).
Then, we'll use
to find the slope.
Let's substitute in our points.

Simplify.

Now, we can leave the slope like that or turn it into a mixed number. As a mixed number, your slope is
.
We'll put that in our equation for a line and...bam!
