<h3>Answer: Choice C</h3>

Choice A is close but we don't use the hypotenuse-leg theorem, as we don't know if the two hypotenuse lengths are the same or not.

Answer:

$4\frac{2}{3}$

Step-by-step explanation:

This is a recurring decimal.

Let x = 4.666666... ⇒ (1)

10x = 46.66666... ⇒ (2)

Subtract equation (1) from equation (2)

10x = 46.66666..

-<u> x = 4.666666... </u>

<u />

9x = 42

x = 42/9

= 14/3

= $4\frac{2}{3}$

What is the surface area-to-volume ratio of the spherical barrel cactus

Butoxors [25]

I can't speak to the cactus specifically, but any sphere has a surface area of $4\pi r^2$ and a volume of $\frac{4}{3} \pi r^3$ , so the area-to-volume ratio wold be

$\frac{4\pi r^2}{ \frac{4}{3}\pi r^3 } = \frac{3(4\pi r^2)}{4(\pi r^3)}$

$= \frac{3\pi r^2}{\pi r^3}\\\\
= \frac{3}{r}$

Where <em>r</em> is the radius of the sphere.

Find ten rational numbers between -1 by 5 and 1 by 2

uysha [10]

Answer:

Step-by-step explanation:

First both the rational numbers should have same denominators. So, find least common denominator

Least common denominator is 10

$\frac{-1}{5}=\frac{-1*2}{5*2}=\frac{-2}{10}\\\\\\\frac{1}{2}=\frac{1*5}{2*5}=\frac{5}{10}\\\\\\$

Now multiply the numerator and denominators of the both the numbers by 10.

$\frac{-2*10}{10*10}= \frac{-20}{100} \ and \ \frac{5*10}{10*10}=\frac{50}{100}\\\\\\Now\ 10 \ rational \ numbers \ between\frac{-20}{10} \ and \ \frac{50}{100} \ is \\\\\\\frac{-19}{100},\frac{-18}{100},\frac{-17}{100},\frac{-16}{100}.\frac{-15}{100},\frac{-14}{100},\frac{-13}{100},\frac{-12}{100},\frac{-11}{100};\frac{-10}{100}$

Solve the equation and explain each step using apropriate Properties<br> -4(3x+6)+6=-30

Lina20 [59]

Answer:

The answer is x=1

Step-by-step explanation:

-4(3x+6)+6=-30

-12x-24+6=-30

-12x-18=-30

-12x-18+18=-30+18

-12x=-12

-12x/-12=-12/-12

x=1
