70% 30 = 21 I highly recommended using google it’s so much easier then this app sometimes because you won’t have to answer other people’s questions hahaha I’m only using it bc I can’t find the answers on google for my homework
The only possibility if a number is not even is that it is odd. Thus, the event would be the product is an odd number.
102% of 250 = 255 Hope this helps ( :
Answer: 45.5yds
Step-by-step explanation:
- the radius is simply half of the diameter so: 91 / 2= 45.5yd
- so the radius is 45.5yds
hope this helps :)
First translate the English phrase "Four times the sum of a number and 15 is at least 120" into a mathematical inequality.
"Four times..." means we're multiplying something by 4.
"... the sum of a number and 15..." means we're adding an unknown and 15 and then multiplying the result by 4.
"... is at least 120" means when we substitute the unknown for a value, in order for that value to be in the solution set, it can only be less than or equal to 120.
So, the resulting inequality is 4(x + 15) ≤ 120.
Simplify the inequality.
4(x + 15) ≤ 120
4x + 60 ≤ 120 <-- Using the distributive property
4x ≤ 60 <-- Subtract both sides by 60
x ≤ 15 <-- Divide both sides by 4
Now that we have the inequality in a simplified form, we can easily see that in order to be in the solution set, the variable x can be no bigger than 15.
In interval notation it would look something like this:
[15, ∞)
In set builder notation it would look something like this:
{x | x ∈ R, x ≤ 15}
It is read as "the set of all x, such that x is a member of the real numbers and x is less than or equal to 15".
