Well 600 so thats there, now we have to add 70 and 34 which makes 104, so since "1" is the hundred we have to add 104 and 600 which gives you 704.
Answer: 704
Hope i helped! :D

Answer:

y=3

(bc it is the same length as its perpendicular counterpart.

x= 9 (same with Z)

(From pythagorean theorem)

6^2+3^2= (root of) 45

and square root 45

and it is the same as its counterpart (which is z)

Step-by-step explanation:

Using Cramer's rule to solve linear systems.

Rzqust [24]

Answer: Last Option

$x=2,\ y=-5$

Step-by-step explanation:

Cramer's rule says that given a system of equations of two variables x and y then:

$x =\frac{Det(A_X)}{Det(A)}$

$y =\frac{Det(A_Y)}{Det(A)}$

For this problem we know that:

$Det(A) = |A|=\left|\begin{array}{ccc}4&-6\\8&-2\\\end{array}\right|$

Solving we have:

$|A|= 4*(-2) -(-6)*8\\\\|A|=40$

$Det(A_X) = |A_X|=\left|\begin{array}{ccc}38&-6\\26&-2\\\end{array}\right|$

Solving we have:

$|A_X|=38*(-2) - (-6)*26\\\\|A_X|=80$

$Det(A_Y) = |A_Y|=\left|\begin{array}{ccc}4&38\\8&26\\\end{array}\right|$

Solving we have:

$|A_Y|=4*(26) - (38)*8\\\\|A_Y|=-200$

Finally

$x =\frac{|A_X|}{|A|} = \frac{80}{40}\\\\x=2$

$y =\frac{|A_Y|}{|A|} = \frac{-200}{40}\\\\y=-5$

The length of giselles arm is 27 inches.The length of her lower arm is 17 inches.About what percent of giselles arm is her lower

elena-s [515]

27 divided by 100 is 0.27 so 0.27 is one percent now 17 divided by 0.27 is about 62.963 so 17 is 62.963% of 27 hope this helped.
