B: $(11)/(20)$ ≥ $(4)/(7)$
C: $(11)/(20)$ < $(4)/(7)$
D: $(11)/(20)$ > $(4)/(7)$

Answers

$(11)/(20)=(11\cdot7)/(20\cdot7)=(77)/(140)\n\n(4)/(7)=(4\cdot20)/(7\cdot20)=(80)/(140)\n\n(77)/(140) < (80)/(140)\to(11)/(20) < (4)/(7)\to\boxed{C.}$

HELP WITH THIS QUESTION PLEASE AND THANK YOUU!!!

Answers

Answer:

s = 35pi units

We can either leave it with pi in the answer or approximate

s= 109.9557429 units

Step-by-step explanation:

Arc length is found by

s = r * theta where r is the radius and theta is given in radians

Changing the angle from 150 degrees to radians by multiplying by pi/180

150 *pi/180 = 5/6 pi

Now we can use the formula

s = 42 * 5/6 pi

s = 35pi

We can either leave it with pi in the answer or approximate

s= 109.9557429 units

Is 8 out of 10 and 25 out of 30 boys playing sports the same

Answers

I think it's not the same.
8 divided by 10 = 1.25
25 divided by 30 is = 1.2

8:10 and 25:30.
They are ratios.

PLZ HELP FAST I NEED TO GET MY GRADE UP DON"T WANT TO DO SUMMER SCHOOL!!!!!!!!!!!!Evaluate n=2

8n+3n-7
-------------
6x2N-3(n-1)
Enter the answer in lowest terms.

Answers

8n+3n-7

8x2=16

3x2=6

16+6-7

22-7=15

6x2=12

12x2=24-3=21+1=22

15/22=5/11

OK 8(2) + 3(2)-7= 16 + 6 - 7 = 22-7 = 15

Next one: 6 x 2(2) - 3(2-1) = 6x4 - 3(1) = 24 - 3 = 21
You used a Capital N I assume you meant n
? I did not see a number value for Big N . so the answers are 15 and 21.

Which rotation about its center will carry a regular decagon onto itself?A. 54
B. 162
C. 198
D. 252
Please explain!!!

Answers

Answer:

D.252

Step-by-step explanation:

In this question, We have to find which rotation about its center will carry a regular decagon onto itself?

A decagon : 10 sided polygon

As we know, a full rotation can be 360°.

For a decagon: 360/10 =36

For a decagon, any multiple of 36 can map onto itself.

In our options only 252 is the multiple of 36.

So, correct answer is option D252
