Mathematics
1 answer:
DiKsa [7]3 years ago
7 0

Answer:

y\in (-\infty ,5]

Step-by-step explanation:

In this problem, we need to write "Twenty times y is at most 100 in interval notation ".

20 times y means, 20y

Atmost means an inequality which is \le

ATQ,

20\times y\le 100

i.e.

20y\le 100\\\\y\le 5

We can also write it as :

y\in (-\infty ,5]

Hence, the required interval notation is y\in (-\infty ,5].

The answer is C. 89 in^2

This is found by (1/2(\pi  r^{2}))+70

r in this equation stands for radius which is half the diameter. Sice the diameter equals 7, the radius equals 3.5

You have to solve this by putting it into a calculator since you can't really solve for an equation with pi in it otherwise.

Hope this helps!
