Prove why 0.87 recurring is equal to the fraction 87/99 (Ps both the 8 and the 7 are recurring)

1 answer:

3 0

0.87
 99 | 870
-792
780
-693
 87
Since it is now 87 again, the process repeats, yielding 0.87 recurring

jenyasd209 [6]

Answer:

The slope is, 3

Step-by-step explanation:

Formula for slope(m) is given by:

$m = \frac{\triangle y}{\triangle x}$

$m = \frac{y_2-y_1}{x_2-x_1}$ .....[1]

Given the statement:

$y_2 = -4$

$y_1 = 2$

$x_2 = 0$ and $x_1 = 2$

Substitute these given values in [1] we have;

$m = \frac{-4-2}{0-2} = \frac{-6}{-2}$

Simplify:

m = 3

Therefore, the value of slope is, 3

Help me solve this and get marked branliest:

bazaltina [42]

Answer:

75°

Step-by-step explanation:

Let's find the size of x°

BCFE has four sides so the sum of its angles sizes is 360°.

● CBE + 110 + 110 + CFE = 360

CFE is equal to 65° since they have the same vertex

● CBE + 220 + 65 = 360

● CBE + 285 = 360

● CBE = 360-285

● CBE = 75

CBE and x° have the same size since they share the same vertex.so:

● x° = 75°

Beth traveled for 8 hours and arrived at her destination 480 miles away. How far would Beth have traveled if she had continued o

V125BC [204]

Answer:

She'd have travelled 120 extra miles, 600 miles in total.

Step-by-step explanation:

480 : 8 = 60 --> 60 miles per hour

60 x 10 = 600 --> 600 miles in 10 hours at that speed

600 - 480 = 120 --> extra miles in the extra two hours at that speed
