PLEASE HELP!!! The right rectangular prism is packed with unit cubes of the appropriate unit fraction edge lengths. Find the vol

never [62]

--------------------------------------------------
Formula :
--------------------------------------------------
Volume = Length x Width x Height

--------------------------------------------------
Find volume :
--------------------------------------------------
$\text { Volume = } 4\dfrac{1}{4} \times 5 \times 2$

--------------------------------------------------
Change to improper fractions :
--------------------------------------------------
$\text { Volume = } \dfrac{17}{4} \times \dfrac{5}{1} \times \dfrac{2}{1}$

--------------------------------------------------
Combine into single fraction :
--------------------------------------------------
$\text { Volume = } \dfrac{170}{4}$

--------------------------------------------------
Simplify:
--------------------------------------------------
$\text { Volume = } 42 \dfrac{1}{2} \ cm^3$

--------------------------------------------------
Answer: Volume = 42 1/2cm³ (Answer c)

Answer:

4

Step-by-step explanation:

This is an <em>infinite geometric series</em>. This has a sum of $\frac{a}{1-r}$

Where

a is the first term, and

r is the common ratio (one term divided by the previous term)

Let's figure out the first 2 terms by plugging in n = 1 first and then n = 2 for the series.

<u />

<u>First term:</u>

$3(\frac{1}{4})^{n-1}\\=3(\frac{1}{4})^{1-1}\\=3(\frac{1}{4})^0\\=3(1)\\=3$

<u>Second term:</u>

$3(\frac{1}{4})^{n-1}\\=3(\frac{1}{4})^{2-1}\\=3(\frac{1}{4})^1\\=3(\frac{1}{4})\\=\frac{3}{4}$

<em>Let's see the common ratio: $\frac{\frac{3}{4}}{3}\\=\frac{3}{4}*\frac{1}{3}\\=\frac{1}{4}$ </em>

<em />

<em>Thus we have a = 3 and r = 1/4</em><em>. Plugging into the formula of the infinite sum, we get:</em>

<em> $s=\frac{a}{1-4}=\frac{3}{1-\frac{1}{4}}=\frac{3}{\frac{3}{4}}=3*\frac{4}{3}=4$ </em>

<em />

<em>So, </em><em>the answer is 4</em>

What is the slope intercept form when m = 1/2 & b = 89 ?<br> Helppppppppp

Zina [86]

Answer:

$y = \frac{1}{2}x + 89$

Step-by-step explanation:

slope-intercept form: y = mx + b

y = (x , y)

x = (x , y)

m = slope = 1/2

b = y-intercept = 89

Plug in the corresponding numbers & variables to the corresponding variables:

y = (1/2)x + 89

$y = \frac{1}{2}x + 89$ is your answer.
