A population was reduced from 3000 to 2500 in the ratio 5:y what is y

Answers

Answer 1

Answer:

Answer:

y=6

solution,

Thepopulationisreducedfrom3000to2509intheratio5:y

$(2500)/(3000) = (5)/(y) \n or \: 2500y = 15000 \n or \: y = (15000)/(2500) \n y = 6$

Hence,theratiois5:6.

Goodluck on your assignment..

HE is 1/3 the length of HG , HE=x-3 and HG=4x-15 find HE

Answers

Answer:

HE=3

Step-by-step explanation:

Equations

With the data provided, we can set up an equation. Then we need to solve the equation. Finally, we use the just-found value of x to calculate HE.

Data:

HE=1/3 HG

HE=x-3

HG=4x-15

Replacing the last two equations in the first:

x-3=1/3(4x-15)

Multiply both sides by 3:

3(x-3)=4x-15

Operate:

3x-9=4x-15

Moving x's to the left and numbers to the right:

3x-4x=-15+9

Joining like terms:

-x=-6

Multiply by -1:

x=6

Since HE= x-3:

HE=6-3

HE=3

Answer:

x=24

Step-by-step explanation:

HE= 1/3(HG)

x-3=1/3(4x-15)

3x-9=4x-15

-x=-24

x=24

Hello, there are three questions and pictures of them in the links If you could solve them that would be awesome, thank you!

Answers

Answer:

1. 1 * $x^(3/6)$ = $x^(3/6)$ (it will be equal to the sixth root of x cube)

2. No, the expression $x^(3)$ X $x^(3)$ X $x^(3)$ will be equal to $x^(3 + 3 + 3 )$ since the powers of numbers with the same base are added

3. B and D 1/ $x^(-1)$ is the same as 'x'

as mentioned in the last answer, powers of numbers with same base are added. hence, option D will be $x^(3/3)$ which will be equal to x

Write the equation in standard form and then find the center (h, k) and
x^2+8x+ y2 + 4y - 5= 0

Answers

Answer:

Center is at (-4, -2) and the radius = 5.

Step-by-step explanation:

Convert to Standard form:

x^2 + 8x + y2 + 4y - 5= 0

Completing the square:

(x + 4)^2 - 16 + (y + 2)^2 - 4 = 5

(x + 4)^2 + (y + 2)^2 = 5 + 16 + 4

(x + 4)^2 + (y + 2)^2 = 25

(x - h)^2 + (y - k)^2 = r^2 Comparing:-

The center is at (-4, -2) and the radius = 5.
