Answer:

49.6

Step-by-step explanation:

A = πr2, (Pi r-squared)

A = (3.14)(8)2

A = (3.14) (64)

A = 198.4

but you need to take 1/4th of that since you are only looking at 1/4th of the circle so,

.25 x 198.4 = 49.6

Which expression is equivalent to x4 • x−2?

<h3>Hey there! </h3><h3>The second " $x$ " is has invisible $1$ </h3><h3>Here, this is what I meant: $x^ 1$ </h3><h3>So, now your equation looks like this: $x^4(x^1$ $-2)$ </h3><h3>Add the exponents: $4 + 1$ $= 5$ </h3><h3>Therefore your answer should be: $x^5 - 2$ </h3><h3>(Note: there's many ways to solve these types of equations, I just gave you the basic method) </h3><h3 /><h3>Good luck on your assignment and enjoy your day! </h3><h3>~ $LoveYourselfFirst:)$ </h3>

$\sqrt{64}=8\\\\8\dfrac17=8.14285714...\\\\8.\overline{14}=8.14141414...\\\\ \dfrac{15}2=7,5\\\\\\ \boxed{\ \dfrac{15}2\ \ \textless \ \ \sqrt{64}\ \ \textless \ \ 8.\overline{14}\ \ \textless \ \ 8\dfrac17\ }$

5.

$\sqrt{18}$ doesn't belong with the other three because it is irrational number
The other three can be expressed as a ratio between two <span>integers.

$-\dfrac{10}2=\dfrac{-10\ }2\\\\-13.4=-13\frac4{10}=\frac{-134}{\ 10}\\\\ 22.\overline7=22\frac79=\frac{205}9\\\\\\ \sqrt{18}=\sqrt{9\cdot2}=\sqrt9\cdot\sqrt2=3\sqrt2$

The left and right page numbers of an open book are two consecutive integers whose sum is 385. Find these page numbers.

Alona [7]

Consecutive integers are integers that follow one another. For example, 2,3,4,5,etc.... are consecutive integers

So algebraically, consecutive integers follow the form x, x+1, x+2, etc...

Since the sum of two consecutive integers is 239, this means:

x%2Bx%2B1=239

2x%2B1=239 Combine like terms on the left side

2x=239-1Subtract 1 from both sides

2x=238 Combine like terms on the right side

x=%28238%29%2F%282%29 Divide both sides by 2 to isolate x

x=119 Divide

So our first number is x=119

So to find the next number, simply add 1 to it to get 119%2B1=120

Answer: So our two page numbers are 119 and 120
