Answer:

The perimeter of a circle is π × d. Here's is the diameter of the circle. Hence, the perimeter of a circle is half of that of the circle that is ½ π × d.

The area of a circle is pi times the radius squared (A = π r²). Learn how to use this formula to find the area of a circle when given the diameter.

Find the 72nd term of the arithmetic sequence -27, -11, 5, ...
MAXImum [283]

Step-by-step explanation:

first identify the common difference

The first term which i will define by u⁰=-27

u¹=u⁰+(1)d where d is the common difference and u¹ is the second term

u¹=-27+d

-11=-27+d

d=27-11=16

The 72nd term would be u⁷¹ since we started from u⁰ as our first term:

Use the explicit relation given by:

u(n)=u⁰+(n)d

u(71)=-27+71(d)

u⁷¹=-27+71(16)

u⁷¹=-27+1136

u⁷¹=1109

OlgaM077 [116]

Answer:

about \: 1.01551

Step-by-step explanation:

No it isn't, because:

{1.08}^{ \frac{1}{5} }  =  { \frac{108}{100} }^{ \frac{1}{5} }  =  { \frac{27}{25} }^{ \frac{1}{5} }  =  \sqrt[5]{ \frac{27}{25} }  = 1.01551

n a 12 ounce bag of trail mix you notice that there are 18 M&amp;Ms. You now purchase a 20 ounce bag of trail mix. How many M&am
Maslowich

30 M&Ms

1) Gathering the data

12-ounce bag of trail mix = 18 M&Ms

20-ounce bag=?

2) Assuming that the M&Ms are placed in following a constant rate we can write the following proportion:

12 --------------- 18

20 --------------- y

<em>Cross multiplying it due to the first property of proportions</em>

<em />

12y =20 x 18

12y = 360

y=30

3) So, I'd expect to find 30 M&Ms at a 20-ounce bag of trail mix.
