6x−3y=−6 solve for y

Answer: 45 (cm)

Step-by-step explanation:

Since the discs have the same thickness, we will think about the areas.

Let say x the new radius:

[tex]\pi*5^2+\pi*20^2+\pi*40^2=\pi*x^2\\\Longrightarrow\ 5^2+20^2+40^2=x^2\\\\\Longrightarrow\ 2025=x^2\\\\\Longrightarrow\ x=\sqrt{2025} =45[/tex]

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.

Answer:

? = 120, ? = 145, respectively

Step-by-step explanation:

? + 60 = 180

? (+ 60 - 60) = 180 - 60

? = 120

35 + ? = 180

(35 - 35) + ? = 180 - 35

? = 145

Answer:

m<RQP = 62°

Step-by-step explanation:

m<RQP = m<PQB + m<RQB

m<RQP = 38° + 24°

m<RQP = 62°

Answer:

BC ≈ 8.6

Step-by-step explanation:

Using Pythagoras' identity in the right triangle , that is

BC² = AB² + AC² = 7.3² + 4.6² = 53.29 + 21.16 = 74.45 ( square root both sides )

BC = [tex]\sqrt{74.45}[/tex] ≈ 8.6 ( to 1 dec. place )

Answer:

B

Step-by-step explanation:

Answer:

Let the number be x

half the number can be written as

x/2

then 5 less than half of the number can be written as

(x/2) - 5

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:

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

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:

r =√[3V/(π h)]

Step-by-step explanation:

V = ⅓ × π r²h

=> multiplied by 3

3V = π r² h

=> find r²

r² = 3V/(π h)

=> find r

r =√[3V/(π h)]

Answer:

[tex]r=\sqrt{\dfrac{3V}{\pi h}}[/tex]

Step-by-step explanation:

Given equation:

[tex]V=\dfrac{1}{3} \times \pi r^2 h[/tex]

To isolate [tex]r[/tex], multiply both sides by 3:

[tex]\implies V \times 3=\dfrac{1}{3} \times \pi r^2 h \times 3[/tex]

[tex]\implies 3V= \pi r^2 h[/tex]

Divide both sides by [tex]\pi h[/tex]:

[tex]\implies \dfrac{3V}{\pi h}= \dfrac{\pi r^2 h}{\pi h}[/tex]

[tex]\implies \dfrac{3V}{\pi h}=r^2[/tex]

Square root both sides:

[tex]\implies \sqrt{r^2}=\sqrt{\dfrac{3V}{\pi h}}[/tex]

As the radius is positive only:

[tex]\textsf{Apply radical rule} \quad \sqrt{a^2}=a, \quad a \geq 0[/tex]

[tex]\implies r=\sqrt{\dfrac{3V}{\pi h}}[/tex]

u + u + 4 + u + 4 =

Answer:

6 sq.cm

Step-by-step explanation:

Answer:

-3a^2= -3*(-6)^2

Step-by-step explanation:

-3a^2 = -3*a^2 = -3*(-6)^2

Answer:

76

Step-by-step explanation:

let the number be x

Then 16 + x/-4 = -3, so

x/-4 = -16-3 = -19 (add -16 on both sides)

x = -4*-19 = 76 (multiply by -4 on both sides)

Answer:

Question 1: c) 12.5 m/s

Question 2: a) The object is not moving.

Step-by-step explanation:

Question 1: 100(m) divided by 8(s) equals 12.5(m/s)

So she goes 12.5 meters per second (m/s).

Question 2: Distance = x variable (horizontal) because the distance depends on the time. Time = y (vertical) because the time is independent.

If the points on the distance or x axis stay the exact same while the time or y axis continues to change, this will lead to a straight horizontal line on a graph and mean that whatever it is being measured for distance, is staying still or 'constant'.
