Answer: 5 faces,8 edges,5 vertices
Step-by-step explanation:5 faces - of which 1 is a square face at the base and 4 isosceles triangle, above.
5 vertices - of which 4 are at the base where 3 edges meet and one above where 4 edges meet.
8 edges - of which 4 are equal in length and at the base and the other 4 are equal in length and above.
Each lion has 1 head. The number of lion heads is L .
Each bird has 1 head. The number of bird heads is B.
The total number of heads of all species is (L + B) = 30
Each lion has 4 feet. The number of lion feet is 4L .
Each bird has 2 feet. The number of bird feet is 2B .
The total number of feet of all species is (4L + 2B) = 100
The system of linear equations is:
L + B = 30
4L + 2B = 100 .

5. 17.2
6. 2.2
7. 3.3
8. 7.9
Step-by-step explanation:
When calculating square root, you always need to find a number multiplied by itself twice that gives the number
Example:
What number multiplied by itself twice gives 64? Number 8! because 8 × 8 = 64
Now cube root is a little bit different. This time, you will need to find a number multiplied by itself three times that gives that number.
Example:
What number multiplied by itself three times gives 125? Number 5! because 5 × 5 × 5 = 125
Hope this helps!
Answer:
0.7
Step-by-step explanation:
-2n +1.8 = 3.2
-2n = 3.2 - 1.8
-2n = 1.4
2n = - 1.4
n = 1.4 ÷ 2 = 0.7
Here is your answer:
Since their no zeros (0) here's your answer:
6.174798604×10^9
