Hello!
To calculate the sale price of the coat, we can simply multiply 150 by .40, then subtract the product from 150.
150 × .40 = 60
150 - 60 = 90
The sale price of the coat is $90.
Answer:
g = 81.
Step-by-step explanation:
f = k/√g where k is a constant
When f = 12 g = 36, so:
12 = k/√36 = k/6
k = 12*6 = 72.
So the relation is:
f = 72/√g
When f = 8:
8 = 72/√g
8√g = 72
√g = 72/8 = 9
g = 9^2 = 81.
7. For this one, we need an equation. Lets make x = the price of the computer. Since the price of the printer is 30% the price of the computer, we can make that .3x, because a number multiplied by .3 will give you 30% of your original number. So, our equation will be:

Since x is the cost of the computer, you have your answer right there. The computer costs $2,028.
8. For this one we're going to need a proportion, but first we need to find out how much of the percentage of seeds Cliff planted.
% of seeds planted per person:
Ali - 40
Ben - 45
Cliff - x
All percentages add up to 100, so we'll make an equation to figure this out:

Therefore, Cliff planted 15% of the seeds. Since Cliff planted 15% of the seeds, and he planted 87 total, 15% of our total number of seeds planted is 87. We can now make a proportion to figure out how many seedlings were planted all together.

We can now cross multiply in order to get a solvable equation:

The total number of seedlings planted was 580.
Sorry if this is confusing at all, hope I helped!
The answer would be less than 1 liter.
Common Sense!
Hope this helped, and please mark brainliest!
