Answer:
x÷5≤15
Step-by-step explanation:
x divides by 5 is less than or equal to 15
'of' means multiply
1/4 of (1/4 times ) the opposite of (-) difference of 5 and a number (5-n) is lesss than 20 (<20)
1/4 times -(5-n)<20
multiply both sides by 1/4
-(5-n)<5
multiply both sides by -1 remember to flip sign
5-n>-5
add n
5>n-5
add 5
10>n
n<10
the number is any number less than 10
Functions are accurate through having one x intercepts which is how you can find which are functions or not.
Answer- B,D,E
Given:
Cylindrical tank volume : 14,130 in³
smaller cylinder : 25 pcs
radius of small cylinders: 3 inches.
Volume of a cylinder = π r² h
14,130 in³ ÷ 25 pcs = 565.20 in³ volume per small cylinder.
565.20 in³ = 3.14 * (3in)² * h
565.20 in³ = 3.14 * 9in² * h
565.20 in³ = 28.26 in² * h
565.20 in³ ÷ 28.26 in² = h
20 in = h
The height of the small cylinder is 20 inches.
The correct answer is the option D.
The definition of plane is: a flat surface with infinite, length, width, but no thickness.
So, by this concept, we can know that a plane is bidimensional. How can we know it is bidimensional? Well, we know that it has no thickness, but length and width, so if a body is projected with lenght and widht, we say that it has two dimensions, but If this object also had depth, it would have three dimensions.
