Answer:

4 √6

Step-by-step explanation:

We have a few right triangles. We know that a²+b²=c², with c being the side opposite the right angle. Representing the side without a value as z, we have:

m²+z² = (8+4)² = 12²

4²+n²=z²

8²+n²=m²

We have 3 equations with 3 unknown variables, so this should be solvable. One way to find a solution is to put everything in terms of m and go from there. First, we can take n out of the equations entirely, removing one variable. We can do this by solving for it in terms of z and plugging that into the third equation, removing a variable as well as an equation.

4²+n²=z²

subtract 4²=16 from both sides

z²-16 = n²

plug that into the third equation

64 + z² - 16 = m²

48 + z² = m²

subtract 48 from both sides to solve for z²

z² = m² - 48

plug that into the first equation

m² + m² - 48 = 144

2m² - 48 = 144

add 48 to both sides to isolate the m² and its coefficient

192 = 2m²

divide both sides by 2 to isolate the m²

96 = m²

square root both sides to solve for m

√96 = m

we know that 96 = 16 * 6, and 16 = 4², so

m = √96 = √(4²*6) = 4 √6

Answer please ...................................
jok3333 [9.3K]

Answer:

#1. 8.27

#2. 36

#3. 22

#4. 7.25

Step-by-step explanation:

#1: 60÷11=5.45  ----> 5.45×16=<u>87.27</u> <This is a non-terminating decimal>

#2: 60÷5= 12 ----> 12×3= <u>36</u>

<u></u>

#3: Games- 35    Won- 14    Lost- 21

      In 1 Game  Manchester won =   14/35  =  2/5 games in 54 Game  Manchester won =  54 x  2/5   games

= 108 / 5

= 21.6

<u>= 22</u>

<u></u>

#4: 6 : 91 ⇒ n : 110

     6(110) ⇒ 91(n)

     660 ⇒ 91n

     660/91 ⇒ n

     <u>7.25=n</u>

<u></u>

What is the slope of the line y=3x-5
xeze [42]

Answer:

The y intercept and the slope are given in the equation. y=mx+b is slope-intercept form. mx is the slope and b is the y intercept. so in y=3x-5, 3x is the slope and -5 is the y intercept (what y is when x is zero).

abruzzese [7]

Answer:

40320 different ways

Step-by-step explanation:

That problem is a permutation one

We have eight people to occupy  one position in a team, without any constraint at all

So

Total number of events   = P(8)

P (8)  =  8!

P (8)  =  8*7*6*5*4*3*2*1

P (8)  =  40320 different ways
