Convert 11.42424242 to a rational expression in the form of a/b , where b ≠ 0.

TiliK225 [7]

11.424242
isolate the repeating part
11+0.424242

focus on the repeating part
0.42424242
how many places till it repeats again?
2
let's say it is x
x=0.42424242
multiply by 100
100x=42.424242

subtract them
100x-x=42.42424242-0.42424242
the infinite repeats cancel and we get
99x=42
divide by 99
$x=\frac{42}{99}$

so
$11.\overline{42}=11 \space\ \frac{42}{99}$

Which is the equation of the given line? (-10,-7) (3,-7)

Vladimir [108]

Answer: $y=-7$

Step-by-step explanation:

The equation of the line in Slope-intercept form is:

$y=mx+b$

Where "m" is the slope of the line and "b" is the y-intercept.

Find the slope with this formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Given the points (-10,-7) (3,-7), substitute values into the formula. Then:

$m=\frac{-7-(-7)}{-10-3}\\\\m=\frac{0}{-13}\\\\m=0$

Substitute the slope and any point into $y=mx+b$ and solve for "b":

$-7=0x+b\\b=-7$

Then, substituting "m" and "b" into the equation $y=mx+b$ , you get that the equation of this line is:

$y=0x-7$

$y=-7$

A regular ice cream cone is 5 inches tall and has a diameter of 2.5 inches. A waffle cone is 7 inches tall and has a diameter of

Lorico [155]

Answer:

a) 8.2 in^3 b) 25.8 in^3 c) 17.6 in^3

Step-by-step explanation:

volume of cone=(1/3)π(r^2)*h

a) 8.2 in^3

regular ice cream cone=(1/3)π(1.25^2)*5=8.18=8.2 in^3

b) 25.8 in^3

waffle cone=(1/3)π(1.875^2)*7=25.77=25.8 in^3

c) 17.6 in^3

waffle cone-regular ice cream cone= 25.8-8.2=17.6 in^3
