Answer:
The correct answer is the first solution set.
Step-by-step explanation:
If we substitute -20 into the equation we get
-20+17≤-3
-3≤-3
So,the inequality is right.
We can check the second one
14+17≤-3
31≤3 The inequality is false.
We can check the last one
-20+17≤-3
-3≤3 It works however there is a difference between the first one and the last one and that is the sign.For the first one there x≤-20 meaning the greatest number x can be is -20.For the last one x≥-20 which means -20 is the least value x can be.
If we substitude -21 into the equation we get
-21+17≤-3
-4≤-3
The inequality is false because -4 is not smaller than -3.
So,the right answer is the first solution set.
Answer:
Step-by-step explanation:
For this exercise you need to remember that the volume of a cylinder can be calculated using the following formula:
Where "r" is the radius and "h" is the height of the cylinder.
Let "x" represents the radius of the base of the cylinder and "y" the height of the cylinder.
Keeping the information given on mind, you can write the following expression:
According to the information given in the exercise, you know that the height of this cylinder is twice the radius of its base. Then:
Therefore, if you substitute that into the first expression and simplify, you get the following expression that represents the volume of the cylinder in cubic units:
Answer:
10.8 hours left
Step-by-step explanation:
If you take 36 and divied it by 10 you get 3.6 then you times it by 3 to get 30% and 10.8 hours left
Correct answer is Naomi calculation is incorrect and correct monthly interest rate is 2%.
Solution:
We are given that quarterly interest rate =6%
That means interest rate per quarter is 6%.
Since quarter means 3 months, interest rate per 3 months =6%
Hence interest rate per one month=6/3=2%
That means monthly interest rate is 2% which means Naomi calculation is incorrect.
