A
rational number is any number that can be written as the
ratio between two other numbers i.e. in the form
Part A:
An easy choice that makes sense is 7.8, right in the middle. To prove that it's rational we need to write it as a ratio. In this case we have
Part B:
We need a number that can't be written as a ratio (because it neither terminates nor repeats). Some common ones are
,
,
and
so it makes sense to try and use those to build our number. In this case
works nicely.
Answer:
The answer is 21 units²
Step-by-step explanation:
To find the area of a right triangle you use the formula A=ab/2
So
A=6×7/2 = 21
$855 but you also have to add the 20 near ball pizzas times however much they were but you must have skipped that by accident
Answer:
y =2
Step-by-step explanation:
Substitute -10 for x:
2(-10)-9y = -38
-20-9y = -38
-9y = -18
9y = 18
y = 2
