Answer:

Step-by-step explanation:

Q4 NO 1

x-5+3x+x+65= 180 degrees

x+3x+x+65-5= 180 degrees

5x+60= 180 degrees

5x=180-60

5x= 120

Divide both sides by 5

x=24

Q4 NO 2

5y-20+y+200= 360 degrees

5y+y+200+20= 360 degrees

6y+220= 360 degrees

6y= 360-220

6y=180 degrees

Divide both sides by 6

y= 30 degrees

Convert the repeating decimal to an improper fraction or mixed number. Include your work in your final answer. \(3.\overline{152}\)

Answers

Answer:

Assuming the repetitive part is 152, i.e. the original repeating decimal is

A=3.152152152....

then  

1000A=3152.152152152152....

subtract A

1000A-A=3152.152152....-3.152152152....

999A=3149

A=3149/999=3+152/999=3 152/999

Therefore

3.152152152.... = 3149/999 or 3 152/999

Find the center and radius of this

Center = ([ ? 1,1])
Radius = [

Answers

[tex]\text{Hello there! :)}[/tex]

Answer:

[tex]\boxed{\text{Center at } (7, -4), \text{ Radius of } 7.}[/tex]

[tex]\text{Formula for a circle: } (x - h)^{2} + (y - k)^{2} = r^{2} \text{ Where:}[/tex]

[tex]h = \text{ x-coordinate of center}\\\\k = \text{ y-coordinate of center}\\\\r = \text{ radius}\\\\\text{Therefore:}[/tex]

[tex]\text{In the equation } (x - 7)^{2} + (y + 4)^{2} = 49:[/tex]

[tex]h = 7\\\\k = -4\\\\r = \sqrt[]{49} = 7 \\\\\text{So:}[/tex]

[tex]\text{Center at } (7, -4), \text{ Radius of } 7.[/tex]

Answer:

Center = (7, -4)

Radius = 7

Step-by-step explanation:

The general equation of a circle is:

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

where (h, k) is the center of the circle and r is the radius.

The equation given is in the form of the general equation of a circle. Knowing this, we will be able to find the center and radius by finding h, k, and r.

[tex](x-7)^{2}+(y+4)^{2}=49[/tex]

We can turn the 49 into 7² (√49 = 7, so 49 = 7²) and turn the equation into:

[tex](x-7)^{2}+(y+4)^{2}=7^{2}[/tex]

Now we can see that:

h = 7

k = -4

r = 7

So the center of the circle would be (7, -4) and the radius would be 7.

An aquarium has dimensions 2x feet, (x – 1) feet, and (x + 2) feet. The aquarium volume must be no more than 280 cubic feet.

Answers

Answer:

[tex]x^3+x^2-2x\leq140[/tex]

Step-by-step explanation:

This is an algebra problem, and we are expected to inequality for the volume of the aquarium.

Given that the

length= 2x

width=(x – 1)

heigth=  (x + 2)

and the volume= 280 ft^3

the inequality expression for the volume is

[tex]2x*(x -1) * (x + 2) \leq 280\\\\[/tex]

open the brackets

[tex]2x*(x -1) * (x + 2) \leq 280\\\\(2x^2-2x)*(x+2)\leq 280\\\\\2x^3+4x^2-2x^2-4x\leq 280\\\\\2x^3+2x^2-4x\leq280[/tex]
