Answer:

Point A is translated to A" by T(0, -6), since A has been shifted 6 units down

check the picture, the translated triangle is A"'B"'C"'.

clearly the angle between B"'A"' and B"A"' is 90 degrees, so we can complete the transformation by a 90° clockwise rotation or a 270° counterclockwise rotation.

from the choices given, we see that is is a 270° counterclockwise rotation.

Answer: A.(o,-6). Ra,270

What is the average (with 0 decimal places) across all schools for the total score? Group of answer choices 1287 1215 1221 1229

Irina18 [472]

Answer:

See explanation

Step-by-step explanation:

Required

The average

The data whose average is to be calculated are not given.

However, the formula to calculate the average is:

$\bar x = \frac{\sum x}{n}$

Assume the data is:

$1287\ 1215\ 1221\ 1229$

This means that the number of schools is 4

So:

$\bar x = \frac{1287+ 1215+ 1221+ 1229}{4}$

$\bar x = \frac{4952}{4}$

$\bar x = 1238$

<em>The average of the assumed data is 1238</em>

5. Find the value of x so that lines s and t are parallel.<br> (7x - 20)°<br> (4x + 16)

Thepotemich [5.8K]

The value of x so that lines s and t are parallel is 12

<h3 /><h3>How to find angles involving parallel lines?</h3>

The angle are alternate exterior angles.

Therefore, alternate exterior angle theorem states that when two parallel lines are intersected by a transversal, then the exterior angles formed on either side of the transversal are equal.

Hence,

7x - 20 = 4x + 16

7x - 4x= 16 + 20

3x = 36

x = 36 / 3

x = 12

Therefore, the value of x is 12.

The sales team at an electronics store sold 48 computers last month. The manager at the store wants to encourage the sales team

brilliants [131]

The number of computers sold has to be 30% more than 48.
30% of 48 plus the numbers sold last month
.3 x 48 +48
14.4 +48
62.4
Round up because the numbers has to be an integer value. (You can't have 2/5 of a computer).

63 computers

Hope this helps :)
