Given I=prt,where I=4.5,p =500,and t=2.5,what is r as a percent?

KIM [24]

PLUG in the numbers
4.5=500 x R x 2.5
divide both sides by 500
0.009=R x 2.5
divide 2.2 to both sides
R=.0036
In percent you have to multiply by 100 which is 0.36%

A recursive rule for an arithmetic sequence is a₁=4;a_n=a_(n−1)−3 .

steposvetlana [31]

The explicit formula of the arithmetic sequence:

$a_n=a_1+(n-1)d$

d - common difference

We have the recursive formula of an arithmetic sequence:

$\left\{\begin{array}{ccc}a_1=4\\a_n=a_{n-1}-3\end{array}\right$

Therefore we have:

$a_1=4,\ d=-3$

Substitute:

$a_n=4+(n-1)(-3)=4-3n+3=7-3n$

<h3>Answer: aₙ = 7 - 3n</h3>

A construction contractor used the equation Y=KX to determine it would cost him $4.90 to buy 2 boxes of nails. How much in each

dem82 [27]

Data: (adopting)
Y = <span>$4.90
K = 2 boxes
x = ? (how much in each box)

Solving:
</span> $Y = K*X$
$4.90 = 2*X$
$4.90 = 2X$
$2X = 4.90$
$X = \frac{4.90}{2}$
$\boxed{\boxed{X = \$\:2.45\:each\:box}}\end{array}}\qquad\quad\checkmark$ <span>
