Since 10 inch pizzas cost $10 each, 15 inch pizzas will cost $15.

Since 10 inch pizzas have an area of 25π square inches and cost $10 each, 15 inch pizzas that have an area of 56.25π square inches will cost $22.5.

For which of the following compound inequalities is there no solution?

Bess [88]

Answer:

(a) $6m \le - 36$ and $m + 24 > 20$

Step-by-step explanation:

Required

Which of a to d has no solution

(a) $6m \le - 36$ and $m + 24 > 20$

We have: $m + 24 > 20$

Sole for m

$m >20 - 24$

$m >-4$

$6m \le - 36$

Divide by 6

$m \le -6$

So, we have:

$m \le -6$ and $m >-4$

$m \le -6$ implies that: m = -6,-7,-8,-9.....

$m >-4$ implies that m = -3,-2,-1,0.....

<em>Hence, there is no solution</em>

Compound interest:

$A=P\left(1+\dfrac rn\right)^{nt}$

where $P$ is the amount you start with, $r$ is the interest rate, $n$ is the number of times interest is compounded per year, and $t$ is amount of time that passes.

$4272\left(1+\dfrac{0.12}1\right)^{1\times3}=4272\times1.12^3\approx6001.85$
