The mean is 35/5=7

v=((7-7)^2+(5-7)^2+(11-7)^2+(1-7)^2+(11-7)^2)/5

v=(0+4+16+36+16)/5

v=14.4

A 150-N bird feeder is supported by three cables. Find the tension in each cable.

Irina-Kira [14]

X axis : -t1 cos 60 + t2 cos 60 = 0

t2 cos 60 = t1 cos 60 ; t2 = t1

Y axis : t1 sin 60 + t2 sin 60 - 150 = 0

since t2 = t1

2t1 sin 60 = 150

t1 ( sqrt(3)/2) = 150/2

t1 = 50 [sqrt(3)]

t2 = 50 [sqrt(3)]

t3 = 150 N

hope this helps

A linear pair of<br> angles have<br> measures of 3m - 6<br> and 3m + 18. What<br> is the value of m?

timama [110]

Answer:

the value of m = 28°

Step-by-step explanation:

the sum of adjacent angles which form linear pair is 180°

so,

=》3m - 6° + 3m + 18° = 180°

=》6m + 12° = 180°

=》6m = 180° - 12°

=》m = 168° ÷ 6

=》m = 28°

A chemist is using 351 millimeters of a solution of acid and water. If 18.2% of the solution is acid, how many milliliters of ac

Zolol [24]

Answer:

The % of of acid in solution = 63.88 ml

Step-by-step explanation:

The solution of acid and water = 351 milliliters

The % of of acid in solution = 18.2% of 351 ml

Or, The % of of acid in solution = $\frac{18.2}{100}$ × 351 ml

Or, The % of of acid in solution = 63.882 ml

Hence ,The % of of acid in solution = 63.88 ml Answer
