Did you ever get the answer??
Answer:
The answer in the explanation
Step-by-step explanation:
The solution of the inequality is all real numbers greater than or equal to 5
so
The solution using interval notation is ------> [5,∞)
and
The solution using set notation is {x ∈ R | x ≥ 5}
Yes.
8 + 1 + 1 = 10, so there are 10 parts to the ratio.
3.5 litres divided by 10 would mean that each part of the ratio is worth 0.35 litres.
The colour is worth 8 parts of the ratio. 0.35 litres multiplied by 8 would give 2.8 litres, meaning 2.8 litres of colour are required.
Fiona has 2.9 litres of colour, which is more than enough to make 3.5 litres of paint mix.
Answer:
They paid $67.45 altogether.
Step-by-step explanation:
First off, we need to set up the problem, I like to do percentage problems like this:
x/58.65 = 15/100
Cross Multiply
100x=58.65x15
When you multiply 58.65 and 15 you get 879.75
Divide
Now we have to divide 879.75 by 100 because 100x=879.75
879.75 divided by 100 is 8.80
So now we know that they paid $8.80 just for the tip.
Add
Now all we have to do is add 8.80 to 58.65
58.65 plus 8.80 is 67.45
The Kerwoods paid $67.45 altogether.
