8.3 repeating as a fraction

1 answer:

7 0

8.333333

let x=8.33333 and 10x=83.33333

10x-x=83.333-8.333

9x=75

x=75/9

x=25/3

x=8 1/3

Now if you meant:

8.383838 then

100x-x=838.3838-8.3838

99x=830

x=830/99

Answer:

2261,9 cm³

Step-by-step explanation:

First, you need to find the area of the base:

$A=\pi r^2$

A=36 $\pi$ cm²

Now let's multiply it for the height:

36π cm² × 20 cm = 720π cm³

= 2261,9 cm³

I need help with this question

AVprozaik [17]

Step-by-step explanation:

Angle formed at the circumference of the circle is half of the angle formed at the center of the same circle.

Hence,

$m\angle ADC = \frac{1}{2} \times m\angle ABC \\ \\ \therefore \: m\angle ADC = \frac{1}{2} \times 40 \degree \\ \\ \therefore \:m\angle ADC = 20 \degree \\ \\$

What is the equation of the line that passes through the point (-3,-8) and has a slope of 4?

coldgirl [10]

Step-by-step explanation:

the easiest approach with a given point and the slope of the line is the point-slope form :

y - y1 = a(x - x1)

where "a" is the slope, and (x1, y1) is a point on the line.

so, we get

y - -8 = 4(x - -3)

y + 8 = 4(x + 3)

if we need the slope-intercept form

y = ax + b

we now simplify the point-slope form

y + 8 = 4x + 4×3 = 4x + 12

y = 4x + 4
