Answer:

5..(b)

Step-by-step explanation:

Pythagoras theorem states that

Hypotenuse(squared)=opposite(squared)+ adjacent(squared)

hypotenuse=?,opposite=3,adjacent=4

hyp(squared)=3(squared)+4(squared)

hyp(squared)=9+16

hyp(squared)=25

find the square root of both sides

hypotenuse=5

Answer:

Option b. (x = 3, y = 20, z = -14)

Step-by-step explanation:

Given:

2x + 2y + 3z = 4

5x + 3y + 5z = 5

3x + 4y + 6z = 5

Solve using Cramer’s rule

∴ $\left[\begin{array}{ccc}2&2&3\\5&3&5\\3&4&6\end{array}\right] =\left[\begin{array}{ccc}4\\5\\5\end{array}\right]$

∴A = $\left[\begin{array}{ccc}2&2&3\\5&3&5\\3&4&6\end{array}\right] = -1$

Ax = $\left[\begin{array}{ccc}4&2&3\\5&3&5\\5&4&6\end{array}\right] = -3$

Ay = $\left[\begin{array}{ccc}2&4&3\\5&5&5\\3&5&6\end{array}\right] =-20\\$

Az = $\left[\begin{array}{ccc}2&2&4\\5&3&5\\3&4&5\end{array}\right] = 14$

∴ x = Ax/A = -3/-1 = 3

y = Ay/A = -20/-1 = 20

z = Az/A = 14/-1 = -14

So, the answer is option b. (x = 3, y = 20, z = -14)

Express 34% as a fraction in simplest form. A.3/4 B.34/100 C.8/25 D.17/50

Verizon [17]

Hey there!

if i am doing this correct it should be

17/50, let me explain!

.34 is 34/100 and both of these numbers are even, thus you can divide it by 2 which will give you 17/50

Hope This Helps!!!
