Solve for n<br><br> N+1=4(n-8)
monitta

Answer:

n = 11

Step-by-step explanation:

n + 1 = 4 (n - 8)

n + 1 = 4n - 32

n - 4n = - 32 - 1

- 3n = - 33

- n = - 33/3

- n = - 11

n = 11

614 divided by 31 round it
ASHA 777 [7]

Answer:

Hi, I'm unsure as to what digit you wanted us to round the answer to, so I rounded the answer to the 4 most commonly used decimal places.

First off, we figure out that <em>614 divided by 31 equals </em><em><u>19.8064516129.</u></em>

Rounded to the nearest thousandth, that's <u><em>19.806.</em></u>

Rounded to the nearest hundredth, that's <u><em>19.81.</em></u>

Rounded to the nearest tenth, that's <u><em>19.8.</em></u>

Rounded to the nearest whole number, that's <u><em>20.</em></u>

A circular region has a population of about 260000 people and a population density of about 135 people per square mine . find th
ValentinkaMS [17]

Answer:

24.76 mine

Step-by-step explanation:

The first thing is to calculate the area of the region, which we can calculate since we have the density and the population. The area would be the quotient between population and density:

260000/135 = 1925.93

The area would be 1925.93 square mine

We know that the area is given by:

A = pi * r ^ 2

we solve to r

r ^ 2 = A / pi

r ^ 2 = 1925.92 / 3.14

r ^ 2 = 613.3

r = 24.76

the radius is equal to 24.76 mine

AB
 It is indicated in the figure and is valid:
 m AB = 49
 m ABC
 Angle resulting from the following subtraction:
 m ABC = 360-107 = 253
 m BAC
 
Angle resulting from the sum of the two angles shown in the figure:
 m BAC = 107 + 49 = 156

 m ACB 
 Angle resulting from the following subtraction:
