Answer/Step-by-step explanation:

Ratio of number of Board games [202020] to Number of Card [888]

$\frac{202020}{888}$ or 202020 to 888 or 202020:888

========================================================

Simplify can be:

$\frac{455}{2}$ or 455 to 2 or 455:2

A circle's radius that has an initial radius of 0 cm is increasing at a constant rate of 5 cm per second.

djyliett [7]

Answer:

a) $r(t)=5t$

b) $A=\pi\cdot r^2$

c) $A=\pi\cdot (5t)^2$

d) $A=25\pi t^2$

Step-by-step explanation:

We know that the circle is increasing its radio from an initial state of r=0 cm, at a rate of 5 cm/s.

This can be expressed as:

$r(0)=0\\\\dr/dt=5\\\\r(t)=r(0)+dr/dt\cdot t=0+5t\\\\r(t)=5t$

a) Radius of the circle, r (in cm), in terms of the number of seconds, t since the circle started growing:

$r(t)=5t$

b) Area of the circle, A (in square cm), in terms of the circle's radius, r (in cm):

$A=\pi\cdot r^2$

c) Circle's area, A (in square cm), in terms of the number of seconds, t, since the circle started growing:

$A=\pi\cdot r^2\\\\A=\pi\cdot (5t)^2$

d) Expanded form for the area A:

$A=\pi\cdot (5t)^2=25\pi\cdot t^2$

Brainliest to correct answer, hurry please!

company A :

30,000 + 0.03(37499) = 31124.97...sales less then 37500

30,000 + 0.03(37501) = 31125.03....sales exceed 37500

30,000 + 0.03(249000) = 37470 ...sales less then 250000

30,000 + 0.03(251000) = 37530....sales exceed 250000

company B :

25,000 + 0.05(37499) = 26874.95...sales less then 37500

25,000 + 0.05(37501) = 26875.05...sales exceed 37500

25000 + 0.05(249000) = 37450...sales less then 250000

25,000 + 0.05(251000) = 37550...sales exceed 250000

so i believe your answer is option b,

company A pays better when sales are less then 250,000, but company B pays better when sales exceed 250,000 <==
