Option 1, 6, 3 are all correct
Volume of the cube is given as 512 cm^3
We also know that
Volume of a cube = (side)^3
Then we can use this formula to find the size of each side of the cube very easily.
Let us assume the length of each side = x
Then
x^3 = 512
= 8
So the length of each side of the cube is 8 cm. I hope you have got the answer you were looking for. You can crosscheck the answer by multiplying 8 three times. You will get the result as 512. This is the only method to solve this problem.
Answer:
84 CDs last week and 26 CDs this week
Step-by-step explanation:
1. Consider a triangle with sides a, b and c.
2. a, b and c can be sides of a triangle only if each of these conditions hold:
i) a+b>c
ii) b+c>a
and iii)a+c>b
3. So the only condition for 3 numbers to be the side lengths of a triangle is that the sum of any 2 of them must be larger than the third number
4. This is called the "triangle inequality".
Answer:
12 students
Step-by-step explanation:
Here is the complete question
Alex surveyed 60 students about their favorite zoo animals and made the circle graph of the results shown below. A circle graph titled Favorite Zoo Animals is shown. There are five sections. One section is labeled Bears, one section is labled Lions, one section is labeled Monkeys, one section is labeled Elephants, and one section is labeled Giraffes.
If the angle measure of the section for giraffes is 72∘, how many students said giraffes were their favorite zoo animal?
Number of students that said the giraffe was their favorite zoo animal = (angle measuring the section for giraffes / sum of angles in a circle graph) x number of students surveyed
the sum of angles in a circle = 360 degrees
(72 / 360) x 60 = 12 students
