Answer:

Step-by-step explanation:

Compare the ratios of corresponding sides, that is

$\frac{AB}{DE}$ = $\frac{2}{12}$ = $\frac{1}{6}$

$\frac{BC}{EF}$ = $\frac{4}{24}$ = $\frac{1}{6}$

$\frac{AC}{DF}$ = $\frac{4}{24}$ = $\frac{1}{6}$

Hence

scale factor of ΔABC to ΔDEF is $\frac{1}{6}$

Answer:

Step-by-step explanation:

This is an geometric series.

Common ratio = second number÷ first number

$= \dfrac{4096}{-1024} = -4$

To get the next number, 256 should be divide by (-4)

$\dfrac{256}{(-4)}= -64 \\\\\\\dfrac{-64}{-4}=16\\\\\\\dfrac{16}{-4}=-4$

The three numbers are : -64 , 16 , -4

I need to find the slope and b Y=mx+b HELP ME

Naddika [18.5K]

Answer:

$y=-\frac{4}{3}x+20$

Step-by-step explanation:

stupid enough

y=mx+b

$\frac{y1-y2}{x1-x2}$

slope = 16-12/3-6

-4/3

$y=-\frac{4}{3}x+b$

plug in x and y

16=-4/3(3)+b

b=20

Find the value of x ………..

andriy [413]

Answer:

135°

Step-by-step explanation:

In a hexagon, sum of all angles = 720

x + x + x + x + 90 + 90 = 720

4x + 180 = 720

4x = 720 - 180

4x = 540

x = 135°

HURRY HELP PLS‼️‼️‼️

Brums [2.3K]

Answer:

Step-by-step explanation:

To solve this problem you need the function

h(t) = -16t2 + v0t + h0

where t = time

v0 is the initial velocity, which in our case is 0

h0 = initial height, which in our case is 256

h(t) = 0 since we want to know when the ball will hit the ground.

0 = -16 t2 + 256

And we can solve for t

If we rearrange the terms we see that this is a difference of 2 squares

0 = 256 - 16t2

0 = (16-4t)(16+4t)

Setting each factor = 0

16-4t=0 16+4t=4

t = 4 t = -4

The second solution is discarded as time cannot be negative.

So the ball will hit the ground in 4 seconds.

BD bisects m m Find m

amm1812

The text of the question is not visible in the answering window. I'll reproduce it here:

BD bisects <ABC.

m <ABD= 2.5x + 8.6

m<CBD = 3.5x - 3.4

Find m<ABC

Answer:

$m\angle ABC = 77.2^\circ$

Step-by-step explanation:

We have an angle ABC and a line BD bisecting it.

If an angle is bisected, then the two formed angles are congruent, that is

$m\angle ABD=m\angle CBD$

Substituting the algebraic expressions for both angles:

$2.5x + 8.6=3.5x - 3.4$

Subtracting 8.6 and 3.5x:

$2.5x - 3.5x = -8.6 - 3.4$

Operating:

$-x = -12$

$x = 12$

The two angles are:

$m\angle ABD=2.5x + 8.6=2.5(12) + 8.6=38.6^\circ$

$m\angle CBD=3.5x - 3.4 = 38.6^\circ$

As expected, both angles have the same measure.

The measure of the total angle ABC is twice any of those:

$m\angle ABC = 2*38.6^\circ=77.2^\circ$

$\mathbf{m\angle ABC = 77.2^\circ}$
