Answer:
3.9 mi/h
Step-by-step explanation:
If the boy is rowing perpendicular to the current, the two vectors form a right triangle.
AB represents the downstream current, BC is the speed across the river, and AC is the ground speed of the boat
AC^2 = 2.4^2 + 3.1^2 =5.76 + 9.61 = 15.37
AC = sqrt(15.37) = 3.9 mi/h
The boat's speed over the ground is 3.9 mi/h.
That would probably be strong negative correlation, however i can't be sure because i can't really see the graph
1: b=9
2: a= 24
3: c=17
4: b=10
Use a^2 + b^2 = c^2 to answer.
1: 12^2 (144) + b = 15^2 (225)
225-144 = 81
Square root 81 = 9
2: a + 49 = 625
625-49=576
Square root 576 = 24
3: 64 + 225 = 289
Square root 289 = 17
4: 576 + b = 676
676-576 = 100
Square root 100 = 10
Answer: They are 59 members in the band
Step-by-step explanation:
given data:
when lined up in 3 = 2 left.
when lined up in 4 = 3 left
when they are lined up in 5 = 4 left
when they are lined up in 6 = 5 left
Solution:
From the given data, we know the band number ends with 9, so we start with 9,29,49,59. We test till we arrive at our desired answer.
59/3 = 19 R 2.
59/4 = 14 R 3.
59/5 = 11 R 4.
59/6 = 9 R 5.
They are 59 members in the band.

Base x Height x 1/2 = Triangle Área
4.8 x 3.6 x 1/2 = 8.64
