Each angle on a triangle would add up to 180 degrees. Since a ladder goes straight up, that angle would be 90 degrees. If you add that with the 39 degree angle, you'd get 129. Subtract that from 180 and you have your answer.

boyakko [2]

Answer:

Mia's method have one advantage that the steps became less than Jenna's method.          

Step-by-step explanation:

Jenna’s method :

5(30 + 4)

=(5)(30) + (5)(4)

=150 + 20

=170

Mia’s method :

5(30 + 4)

=(5)(34)

=170

To find : Explain why both Jenna and Mia arrived at the same answer and the advantage of one method over the other ?

Solution :

The method of both were different but correct.

One apply distributive property and other apply direct calculation.

So, both Jenna and Mia arrived at the same answer

Z_ {13} = 0.5,\ Z_ {17} = 2.5

Step-by-step explanation:

The z-scores give us information about how many standard deviations from the mean the data are. This difference can be negative, if the data are n deviations to the left of the mean, or it can be positive if the data are n deviations to the right of the mean.

To calculate the Z scores, we calculate the difference between the value of the data and the mean and then divide this difference by the standard deviation.

so  

Z = \frac{x- \mu}{\sigma}.

Where x is the value of the data, μ is the mean and σ is the standard deviation

In this case :

μ = 12 $/h

\sigma = 2 $/h

We need to calculate the Z-scores for x = 17 and x = 13

Then for x = 17:

Z_{17} = \frac{17-12}{2}.

Z_{17} = 2.5

Then for x = 13:

Z_{13} = \frac{13-12}{2}.

Z_{13} = 0.5

Therefore the answer is:

Z_ {13} = 0.5,\ Z_ {17} = 2.5

Sam gave jen 1/2 of his jujubes .jen ate 1/2 ofthe jujubes and gave rest to kyle.kyle kept 8 of the jujubes and gave the last 10
erastovalidia [21]
Let x = the # jujubes Sam had
he gave x/2 to jen
jen eats half of it  =    1/2(x/2) =    x/4
the remaining  x/4 he gave to kyle
kyle kept 8 and gave 10 to Kim
so
             x/4 - 8 = 10
             x/4 = 18
             x =72
thus    jen had 36 jujubes
jen eat    18  jujubes
