The population of a colony of beetles grows 30% each week. If the initial population is 65 beetles, how many beetles will be the

Crazy boy [7]

This is question of geometric sequence, equation of growth for this matter. The explicit formula for geometric sequence is given by:

a(n) = a(0)r^(n-1)

where;
a(n) = population after time "n"
a(0) = Initial population = 65
n = time = 5 weeks
r = common ratio = (100+30)% = 1.3

Substituting, beetles after 5 weeks will be;
a(5) = 65*1.3^(5-1) = 185.65 ≈ 186 beetles

Raven needs new winter boots. Both Shoe Town and LaceUp shoe stores carry the boots

g100num [7]

Answer:

Raven should buy the boots at LaceUp since total cost is lower ($77.54)

Step-by-step explanation:

price of the boots at Shoe Town:

[$85.95 x (1 - 15%)] x (1 + 7.16%) = $73.06 x 1.0716 = $78.29

price of the boots at LaceUp:

{[$85.95 x (1 - 10%)] - $5} x (1 + 7.16%) = ($77.36 - $5) x 1.0716 = $72.36 x 1.0716 = $77.54

price of the boots at Run, Don't Walk (online store):

$71.99 + $6.50 = $78.49

How many solutions does this equation have?

iogann1982 [59]

<h3>Explanation</h3>

Solve the equation for s-term.

$- 4s = - 10 - 5s \\ - 4s + 5s = - 10 \\ s = - 10$

Answer Check by substituting s = -10 in the equation.

$- 4( - 10) = - 10 - 5( - 10) \\ 40 = - 10 + 50 \\ 40 = 40 \: \: \tiny \boxed{ \green \checkmark}$

Solutions

No Solutions

When both sides of equation are different. For example, 3 = 4 which makes the equation false. That means the equation is false for all real numbers, thus having no solutions.

One Solution

A common type solution because you see this type of solution a lot. If you can solve the equation for a variable like x = 2 or s = 0. That's one solution.

Infinitely Many Solutions

When both sides are same like 3 = 3 or 7 = 7. That means the equation is true for all real numbers. You can see this type of solution by solving the equation with same both sides like 3x+2 = 3x+2.

<h3>Answer</h3>

Because we can solve the equation for s-term. Therefore the answer is one solution
