You know three team members do the butterfly. One more team member does the breaststroke. Therefore, 4 members do the breaststroke, because 3 + 1 = 4. Three times more do the sidestroke than the breaststroke, so you have to multiply 4 by 3 and get 12. 12 members do the sidestroke. If you add the 3 memebers doing the butterfly, the 4 memebers doing the breaststroke, and the 12 members doing the sidestroke, you get 19. Since the other half of the team is doing the crawl, you have to multiply 19 by two to get the whole team. 19 times two is 38. There are 38 members on the swim team.
A=2w x w
With w being the width of the rug and A being the total area/surface of the rug
Answer:
B. 29º
Step-by-step explanation:
Given that BCDE is a parallelogram, then
and A, E and D are collinear. Then, angle E inside triangle ABE and angle D inside parallelogram BCDE have the same measure. That is:
(1)
In addition, the sum of internal angles in triangles equals 180º, which implies that:
(2)
If we know that
and
, then
is:
![\angle A = 180^{\circ}-\angle B - \angle E](https://tex.z-dn.net/?f=%5Cangle%20A%20%3D%20180%5E%7B%5Ccirc%7D-%5Cangle%20B%20-%20%5Cangle%20E)
![\angle A = 180^{\circ}-100^{\circ}-51^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20A%20%3D%20180%5E%7B%5Ccirc%7D-100%5E%7B%5Ccirc%7D-51%5E%7B%5Ccirc%7D)
![\angle A = 29^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20A%20%3D%2029%5E%7B%5Ccirc%7D)
Hence, correct answer is B.
Create an equation where x equals extra messages
15 + .05X = 24.60
.05x = 9.60
x=192
So she sent 192 EXTRA messages. Add this to the original 600 and you get 792 messages
