Answer: Distance between dolphin and helicopter = 93.5 feet
Explanation:
Distance at which dolphin swimming below the ocean= (-) 18 feet
(it is represented as the negative number as it denotes the distance below the ocean)
Distance at which helicopter is above the ocean = (+) 75.5 feet
(it is represented as the positive number as it denotes the distance above the ocean)
Distance between dolphin and helicopter = 75.5 - (-18) feet
= 75.5 + 18 feet
= 93.5 feet
We have to identify the statement about the plane which is not true.
1. Consider the first statement,
" A plane can be thought of as flat". It is true as plane is a flat surface.
2. Consider the second statement,
"The surface of a plane is made up of points". It is true as plane is a flat surface which is made up of points.
3. Consider the third statement,
"A plane can be seen". It is not true as plane is a flat surface which can not be seen.
4. Consider the fourth statement,
"A plane extends infinitely in all directions". It is true as plane is a flat surface that extends infinitely along its edges.
Answer:
B
Step-by-step explanation:
(x+7)(x+5)
First question
Volume = height * radius*radius*3.14
5*3*3*3.14 = 141.3 in3
Second qustion
Violume = height * radius * radius * 3.14
28*8*8*3.14= 5626.88 cm3
So the answer is 1875.63 because it's the closest
