K=ar/p isolate R
K/a=R/p divide a to both sides
Kp/a=r multiply p to both sides
Kp/a=r is your answer

The answer is C because you divide the P so you get KP=AR then you finish the rest

Increasing at a constant rate,a company's profits y have gone form $535 milion in 1985 to $570 million in 1990. Find the expecte

omeli [17]

Answer:

total profit=$607.278

Step-by-step explanation:

company's profit in 1985= $535 million

company's profit in 1990=$570 million

growth rate = $\frac{570-535}{535}\times 100$

= $\frac{35}{535} \times 100$

= 6.54 %

profit in year 1995 will be = $\frac{6.54}{100}\times 570 =\ \$37.278$

hence total profit= $570+$37.278

= $607.278

A sea turtle swims at a speed of 27 kilometers per hour. A girl swims 14 decimeters per second. 1 m = 10 dm 1000 m = 1 km How mu

insens350 [35]

The sea turtle's speed is
$v_{t} = (27 \, \frac{km}{h} )*(1000 \, \frac{m}{km} )*( \frac{1}{60} \, \frac{h}{min} ) = 450 \, \frac{m}{min}$

The girl's speed is
$v_{g} = (14 \, \frac{dm}{s} )*( \frac{1}{10} \, \frac{m}{dm} )*(60 \, \frac{s}{min} ) = 84 \, \frac{m}{min}$

The ratio of the turtle's speed to that of the girl is
$\frac{v_{t}}{v_{g}} = \frac{450}{84} =5.357$

Answer: 5.36 faster (nearest hundredth)

Simplify the expression. (81x^12/3x^3)^1/3

ser-zykov [4K]

Raise each number to the power outside the parentheses.

$\left( \dfrac{81x^{12}}{3x^3} \right) ^{ \frac{1}{3} } = \\

= \left( 27x^{12-3} \right) ^{ \frac{1}{3} } = \\

= \left( 27x^{9} \right) ^{ \frac{1}{3} } = \\

= \left( 3^3x^{9} \right) ^{ \frac{1}{3} } = \\

= \left( 3^3 \right) ^{ \frac{1}{3} } \times \left( x^{9} \right) ^{ \frac{1}{3} } \\

= \left( 3^{3 \times \frac{1}{3} } \right) \times \left( x^{9 \times \frac{1}{3} }} \right) \\

= 3^1 x^3 \\

= 3x^3
