Answer:
10 edges
Step-by-step explanation:
we know that
The Euler's formula state that: In a polyhedron, the number of vertices, minus the number of edges, plus the number of faces, is equal to two
in this problem we have
substitute the given values
solve for E
Combine like terms in the left side
subtract 12 both sides
Multiply by -1 both sides
You will have to divide 353 millimeters by 4:
353 ÷ 4 = 88.25
now we have to multiply 88.25 by 9 (5+4), the total millimeters of only one portion of this drug
88.25 x 9 = 794.25
So he will make 794.25 millimeters of drug (that is if he has the part a too)
(If you should round 88.25 to 88, the answer would be 88 x 9 = 792)
Answer:
a) First Average mean = 21
b) Current mean = 22
Step-by-step explanation:
Formula For mean =
Sum of Terms/ Number of terms
a)Sandy had test scores of 20, 25, 17, 22, and 21.
Number of terms = 5
Mean = (20 + 25 + 17 + 22 + 21)/5
= 105/5
= 21
b) On the next 3 test Sandy's score were 24, 24, and 23
To calculate this current mean, we will add the first 5 test scores, with this current 3 test scores and then find the average.
Mean = (20+ 25+ 17 +22 +21 + 24 + 24 + 23)/8
Mean = 176/8
Mean = 22

Answer:
A' (1, 2)
Step-by-step explanation:
You can tell so from the graph. Since it's A' and not A, you don't have to rotate the triangle in order to find the solution.
