Answer 2
Answer: First thing you should know is that Pi never ends. However, 3.14 is the first starting numbers. In math this is used to find areas of objects and such. I hope this helped!

5x+2+6x+9=10x+5 solve the equation.

Answers

Simplify both sides of the equation.

5x+2+6x+9=10x+5

(5x+6x)+(2+9)=10x+5(Combine Like Terms)

11x+11=10x+5

11x+11=10x+5

Subtract 10x from both sides.

11x+11−10x=10x+5−10x

x+11=5

Subtract 11 from both sides.

x+11−11=5−11

ANSWER: x=−6


5x+2+6x+9=10x+5

add like terms

11x + 11 = 10x + 5

11x + 11 - 11 = 10x + 5 - 11

11x = 10x - 6

11x - 10x = 10x - 10x - 6

x = -6 Answer


Find the radius of a circle on which a central angle measuring 2π/3 radians intercepts an arc on the circle with a length of 35π kilometers.

Answers

The radius of the circle is of 52.5 kilometers.

This question is solved using the length of arc formula, which states that:

L = r\theta

In which:

  • L is the length of the arc.
  • r is the radius.
  • \theta is the measure of the central angle, in radians.

-------------------------

In this question:

  • Central angle of 2π/3 radians, so \theta = (2\pi)/(3)
  • Length of 35\pi.

Thus, to find the radius, we solve for r.

L = r\theta

35\pi = r(2\pi)/(3)

2\pi r = 105\pi

Simplifying both sides by \pi

r = (105)/(2) = 52.5

The radius of the circle is of 52.5 kilometers.

A similar question is given at brainly.com/question/15162755

Answer:

Radius= 105/2 km

Step-by-step explanation:

The formula for arc length (in radians) is Arc Length = Radius*Angle(in radians)

The arc length is 35π km and the angle is 2π/3

Plug in the values and solve for r

35π = (2π/3)*r

35π*3/2π= r

r = 105/2 km  or 52.5 km

an ecosystem which is 10 km squared contains a population of 1000 squirrels what is the population density of the squirrels in this ecosystem

Answers

Answer:

100 squirrels/km^2

Step-by-step explanation:

we know that

To find the population density of the squirrels in the ecosystem, divided the quantity of population of squirrels by the area of the ecosystem

so

1,000/10=100 squirrels/km^2

Chet's father is five times as old as Chet. In six years, his father only be three times as old. How old is Chet now?

Answers

12 bc if u take a random number like 6 times it by 5 you get thirty so his dad is 30 years old and chet is 6 then add six years and chet is 12 and his dad is 36 and 12 goes into 36 3 times. I hope this helped. :-)

Substitution for 4x+y=9 and y=-7

Answers


{y=-7

{4x+y=9            Substitute y.


4x+(-7)=9

4x-7=9        /+7

4x=16     /:4

x=4

Solution; (4; -7)

4x + y = 9

y = -7

Plug it in:

4x - 7 = 9

Add 7 to both sides:

4x = 16

Divide 4 to both sides:

x = 4

Plug this back into the equation:

4x + y = 9

4(4) + y = 9

16 + y = 9

Subtract 16 to both sides:

y = -7

So our solution is (4, -7)
