Answer:
20
Step-by-step explanation:
First, rewrite the numbers in numerical order:
8, 10, 10, 15, 15, 20, 20, 20, 20, 25, 25, 25, 35
Then find the middle number: (note there's 6 numbers on each side of <u>20</u>)
<em>8 10 10 15 15 20 </em><u>20</u> <em>20 20 25 25 25 35</em>
Hope this helps!
k = 7
given y varies jointly with x and w then the equation relating them is
y = kxw ← k is the constant of variation
to find k use the condition when y = - 42, x = 2 and w = - 3 , then
- 42 = k × 2 × - 3
- 42 = - 6k ( divide both sides by - 6 )
7 = k
constant of variation is k = 7
pretty sure its 55° because the total should be 180* and I know that C is a right angle aka 90° and 90 + 35 = 125 and 180-125=55
18
-3-6= -8 but since its absolute value it'll be 8 so 8 plus 10 = 18

Use the geometric mean to solve for x. The side x is common to both the triangle that has the base of 3 and the triangle that has a base of 3 + 7, so x is the geometric mean. Set up that proportion as follows:
