-6 < 3n + 1 < = 10
solve from the center out to both the left and the right. subtract 1
-7 < 3n <=9
divide by 3
-7/3 -7/3 = -2 1/3 so if we are to use INTEGERS ONLY that would have to be rounded to -2 because the inequality is saying x has to be GREATER than negative two and one third.
Checking: -6 < 3(-2) + 1 < = 10
-6 < -1 < = 10
Answer:
Option C.
Step-by-step explanation:
we have that
The correct question is
Louis calculated the height of a cylinder that has a volume of 486pie cubic centimeters and a radius of 9 centimeters her work is shows below
V=BH
STEP 1: 486pie=pie9^2h
STEP 2: 486pie=81pieh
STEP 3: 486pie/81pie=81pie/81pie h
STEP 4: h=6pie cm
what error did Louise make when calculating the height of the cylinder
A. in step 1 she substituted into the volume formula incorrectly
B. in step 2 she calculated 9^2 incorrectly
C. in step 4 the pie should have canceled making the correct answer 6 cm
D. Louise correctly calculated the height of the cylinder
we know that
The volume of the cylinder is equal to
where
B is the area of the base
h is the height of the cylinder
we have
Find the area of the base B
substitute
step 1
substitute the values in the formula of volume
step 2
step 3
Divide both sides by 81π
step 4
Simplify
rewrite
therefore
In step 4 the pie should have canceled making the correct answer 6 cm
