Answer:

D. a reflection over the y-axis

Step-by-step explanation:

We can see that ΔQRS has been directly translated across the y-axis to form ΔQ'R'S'. (It mirrors across)

This is the number 27 thousand

==============================================

Explanation:

There are three slots and 30 choices per slot. Repeats are allowed.

So there are 30*30*30 = 27,000 different locker combos.

Answer:

Step-by-step explanation:

But I solve like this and the answer is 9 I am student girl.

Answer:

The girl didn't follow PEMDAS

Step-by-step explanation:

PEMDAS is the order in which you solve mathematical equations.

Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.

If you add before multiplying you'll get a completely different answer.

The boy followed PEMDAS, while the girl didn't.

The median of the data is: 7

Answer:

∠ 1 = 36°

Step-by-step explanation:

Supplementary angles sum to 180° then

∠ 2 + ∠ 3 = 180° , that is

∠ 2 + 126° = 180° ( subtract 126° from both sides )

∠ 2 = 54°

Complementary angles sum to 90° , then

∠ 1 + ∠ 2 = 90° , that is

∠ 1 + 54° = 90° ( subtract 54° from both sides )

∠ 1 = 36°

Answer:

a translation 7 units down

Step-by-step explanation:

the value of -7 will be added to the value of y in the original one ( y = x2) and it will decrease it by 7 units

Answer:

m<RQP = 62°

Step-by-step explanation:

m<RQP = m<PQB + m<RQB

m<RQP = 38° + 24°

m<RQP = 62°

Answer:

Page 3 - the y-intercept would remain at 5 and the slope would be 3 times the upward slope.

Page 5 - the y-intercept would remain at -2 and the slope would be 1/4 instead of 5

Step-by-step explanation:

In point slope form the slope and y-intercept can be read directly from the equation.

y = mx + b where m is the slope and b is the y-intercept.

Answer:

a = -5

Step-by-step explanation:

IF A = -5

6 ( - 5 ) + 9

- 30 + 9

-21

-21 is less than -15 so it works

Answer:

Step-by-step explanation:

The formula is the same almost as the previous question you posted.

You want to find the major arc. That's almost the whole circle. If it was the whole circle,  the formula would be 2 * pi * r

But we only want a part of it. Just how big is the angle we use in the formula?

A circle has 360 degrees to go around it. We've cut out a slice of it that is 30 degrees.

The remaining part is 360 - 30 = 330

Arc length = angle / 360  * 2 * pi * r

r = 3 m

Arc length = 330 / 360 * 2 * pi * 3

Arc length = 0.9167 * 6 * 3.14

Arc length = 17.27

Answer:

X (2, 1)

Y (2, 3)

W (5, 5)

Step-by-step explanation:

The current points are:

X (-2, -1)

Y (-2, -3)

W (-5, -5)

Now, after rotating 180 degrees around the origin, here is what points Y, Y, and W would look like:

X (2, 1)

Y (2, 3)

W (5, 5)

Plot these new points on the graph, and you'll have a new figure which will be rotated to 180 degrees.

I have also provided you with a graph, showing both, the original and the rotated version, below.

5 m/s · 12 s = 5 m · 12 = 60 m

Answer: in 12 seconds that car has gone 60 metres.

Answer:

A car travels at a constant rate of 5 metres per second.

That means that for every second,the car travels 5m/s.

The question is asking you for how far the car travelled after 12 seconds.Muntiply 12 to bottom and top.

5m/1s*12/12=60/12

The car travels 60 metre in 12 seconds

Step-by-step explanation:

we would calculate the line of sight between the 2 lasers.

then we would create a line that goes through the middle point between the 2 lasers and is perpendicular to the line between the lasers. if we are lucky, then "You" is on the same perpendicular line. if not, we need to shift our starting point to a point where the perpendicular line hits the wall of the room.

by following that perpendicular line precisely, we we always have the same distance from both lasers.

Answer:

C=9

Step-by-step explanation:

If A, B, and C are all single digits the mimimum sum for AB would be 10 as it is a two-digit number (or 11 if you do not consider 0 a digit)

AB-(A+B)=C

10-(1+0)=9 or 11-(1+1)=9

therefore C=9

Answer:

? = 120, ? = 145, respectively

Step-by-step explanation:

? + 60 = 180

? (+ 60 - 60) = 180 - 60

? = 120

35 + ? = 180

(35 - 35) + ? = 180 - 35

? = 145

Answer:

Step-by-step explanation:

What do you know about y?

Nothing. It could be odd or even. You can't take the chance. So you need to start your list with 2y

That means that 2y + 2 is the second member in your list

2y + 4

2y + 6

2y + 8

2y + 10

But notice you only have 5 numbers. 2y + 10 cannot be the answer.

The answer must be 2y + 20
