Answer:

\left[\begin{array}{cc}-230&380\\-170&60\end{array}\right]

Step-by-step explanation:

Notice that you are being asked to perform the product of a scalar (the number "-10" times a 2 by 2 matrix.

Such type of product requires the multiplication of each element of the matrix by the scalar "-10"

That means that the element 23 gets transformed into "-230"

The element -38 gets transformed into "380"

The element 17 gets transformed into "-170"

and lastly, the element -6 gets transformed into "60"

\left[\begin{array}{cc}1-230&380\\-170&60\\end{array}\right]\left[\begin{array}{cc}-230&380\\-170&60\end{array}\right]

Such modification gets reflected in the second matrix listed among the possible answers.

given triangle UVW is congruent to triangle TSR find the values of x (12x-7), y (5y-33), and z (3z+14)
timama [110]

Answer:

Step-by-step explanation:

Find the image attached. For two triangles to be congruent, then the sides of UVW is equal to that of TSR

From the diagram given

TR = UW

Given

TR = 50

UW = 3z+14

Equate and find z;

3z+14 = 50

3z = 50-14

3z = 36

z = 36/3

z = 12

VW = RS

Given

VW = 27

RS = 5y - 33

Equate

5y-33 = 27

5y = 27+33

5y = 60

y = 60/5

y = 12

Also TS = UV

TS = 53

UV = 12x+7

Equate:

12x-7 = 53

12x = 53+7

12x = 60

x = 60/12

x = 5

Hence x = 5, y = 12 and z = 12

Now that Oakland Auto Reapir has a different owner, its mechanics make $14.20 per hour. That is 25.1% less than they originally
Serhud [2]

Answer:

$18.96

Step-by-step explanation:

Now the mechanics earn $14.2 per hour, which is 25.1% less than before.

If we say that the earnings before were 100% (to facilitate our calculation and understand better), now the earrings are (100-25.1)%=74.9%. This is, now they make the 74.9% of what they used to made.

So:

74.9% = 14.2

Let's multiply both sides by 100%/74.9% to make a 100% appear at the left side (see that multiply and divide by 74.9 will make it desapear):

74.9% *(100%/74.9%) = 14.2 * (100%/74.9%)

100% = 14.2 * (100%/74.9%)

And (100%/74.9%) is equal to 1/0.749, they are the same. So:

100% = 14.2 * 1/0.749

100% = 18.96

So, before the new manager they used to make $18.96. (you can verify by multiplying it by 74.9% and the result is 14.2)
