Answer:
151.9 if the side length of the pentagon/ base of each triangle is 6 m
Step-by-step explanation:
if the side length of the pentagon/ base of each triangle is 6 m then it is a pretty simple question, we just need to add the surface area of the base pentagon and each triangle.
We have the area of the base, so we just need the triangles. The area of a triangle is .5bh, where the base of a triangle here is one side of the pentagon and the height is that indicated red 6. so that means one triangle has an area of .5*6*6 or 18. There are 5 triangles total so that means that with all the triangles there is an area of 90. Adding that to 61.9 gets us 151.9. let me know if you need any more help.
Answer:
B 14 is the correct answer
Total money before purchasing = $30
Cost of each song = $1.20
Solution:
According to the table,
No. of songs Amount
2 27.60
3 26.40
4 25.20
Difference between amount she have after bought 3 songs to 2 songs:
27.60 – 26.40 = 1.20
Difference between amount she have after bought 4 songs to 3 songs:
26.40 – 25.20 = 1.20
So, the cost of each song = $1.20
Amount of money she had after purchasing one song = $27.60 + $1.20
= $28.80
Tasha initially had before purchasing songs = $28.80 + $1.20
= $30
Hence Tasha initially had $30 before purchasing songs and the cost of each song was $1.20.
ANSWER
No solution
EXPLANATION
The first equation is

and the second equation is

We equate the two equations to obtain;

This implies that


There is no real number whose square is -1.
Therefore, the equation has no solution.
