Okay. So no more than 660 minutes will be spent cutting the lawn. The sign will be less than or equal to. A and D are out, because those show greater than or equal to symbols, which is not what we're looking for. x represents the number of lawns mowed, which is an average of 40 minutes, and he will have done 110 minutes. The equation is 40x + 110 ≤ 660. The answer is C.
Answer:
length = 15 feet.
Step-by-step explanation:
This paper is 15 feet across on any side. Who will deliver this monster?
Area = s^2 where s is the length of 1 side.
Area = 225 feet^2 (You sure this isn't inches).
s^2 = area
s^2 = 225 Take the square root of both sides of the equation.
sqrt(s^2) = sqrt(225)
s = 15
Answer: There will be 0.04 grams will be left in the sample after 20 years.
Step-by-step explanation:
Since we have given that
Here, Initial amount of radioactive substance = 400 grams
We need to find the amount of substance that will be left in the sample after 20 years.
So, t = 20 years
So, it becomes,
Hence, there will be 0.04 grams will be left in the sample after 20 years.
Assume the number we are looking for in n
we want to know the value of n that makes 1/7 divided by n is 14
Transforming this to an equation:
(1/7) / n = 14
this means that:
1/7 = 14n
1 = 7 x 14n
1 = 98n
n = 1/98
Therefore:
1/7 divided by 1/98 will give us 14
Answer:
the shirt before taxes is $18. the shirt after taxes is 19.53
Step-by-step explanation:
you multiply 20x.10 and you'll get 2. so you subtract 2 from 20, that's $18.
to get taxes, you multpliply 18x.085 and you get $1.53.
you then add $1.53 to 18 and you get your total price of $19.53
