Suppose that each semester at a particular community college Manuel has to pay $1478 in tuition and $121 in fees.

Kamila [148]

Answer:

Step-by-step explanation:

Let x be time, in semesters, remaining before Manuel graduates. We find that Manuel's expenses are:

$1478/semester in tuition, and

$121/semester in fees

1. x semesters remaining: fees

Remaining cost for fees, y, is the product of the fee times the number of semesters, x:

y =($121/semester)*x

y = ($121)*x

2. x semesters remaining: tuition

Remaining cost, y, is the product of the tuition (times the number of semesters, x.

y = ($1478/semester)*x + ($121/semester)*x

y = ($1599)*x

3. x semesters remaining: tuition and fees

Remaining cost, y, is the sum of the products of the tuition (times the number of semesters, and the fees (tix.

y = ($1478/semester)*x + ($121/semester)*x

y = ($1599)*x

Javier simplified the expression below. Find and describe the three mistakes he made.

OverLord2011 [107]

$( \dfrac{20x}{5x^8})^-^3$

Take out the constants

$( \dfrac{20}{5} * \dfrac{x}{x^8} ) ^-^3$

$(4*\dfrac{x}{x^8} ) ^-^3$

Use the rule : $\frac{{x}^{a}}{{x}^{b}}={x}^{a-b}
$

$(4x^1^-^8)^-^3$

$(4x^-^7)^-^3$

Use the negative power rule : ${x}^{-a}=\frac{1}{{x}^{a}}
$

$\frac{1}{4(x^-^7)}^-^3$

$\frac{1}{4^3(x^-^7)}^-^3$

$\dfrac{1}{64x^-^2^1}$

$\dfrac{1}{64* \dfrac{1}{x^2^1}}$

$\dfrac{1}{64 \dfrac{}{x^2^1}}$

$= \dfrac{x^2^1}{64}$

<h3>How to find height of a rectangular prism?</h3>

Volume of a rectangular prism = lwh

where

l = length
w = width
h = height

Therefore,

10000 = 25 × 10 × h

10000 = 250h

h = 10000 / 250

h = 40 cm
