Answer:

x=2

Step-by-step explanation:

g(x)=∛(x-2) -Substitute g(x)=0

0=∛(x-2) -Swap the sides of the equation

∛(x-2)=0

∛(x-2)=0 -Set the radicand equal to 0

x-2=0

x-2=0 -Move the constant to the right hand side and change its sign

x=2

Answer: 20

Step-by-step explanation:

First let's find the perimeter: 2(l+w) = 2 (100 + 60) = 2 (160) = 320m

Now let's divide 6400 by 320 = 20 metres

The constant width of the path is 20 m.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares that cover a closed figure's surface is its area.

Length of park = 100 m

Breadth of park = 60 m

As, the area including the path = 6400 m²

Area of path + Area of width = 6400 m²

100 x 60 + Area of width = 6400

Area of width = 400 m²

Area of width = 20 x 20 m²

Thus, the width of path is 20 m.

Equivalent Fractions with the LCD

1/3 = 3/9

5/9 = 5/9

Solution:

Rewriting input as fractions if necessary:

1/3, 5/9

For the denominators (3, 9) the least common multiple (LCM) is 9.

LCM(3, 9)

Therefore, the least common denominator (LCD) is 9.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

Answer:

45.8

Step-by-step explanation:

I think that is the correct answer

Answer:

B=11

Step-by-step explanation:

b=10 a=8

b=? a=9

Either you can cross multiple 10x9=90/8 (11.25, round down to 11), or you can look that 9 is 8+1, so of we do the same process to b then we would find our awnser. 10+1=11.

When a is 9 then, the value of b will be;

⇒ b = 45/4

What is Proportional?

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

'b' is directly proportional to a.

And, b is 10 when a is 8.

Now,

Since, 'b' is directly proportional to a.

Hence, We get;

⇒ b = ka

Where, k is constant of proportionality.

Here, b is 10 when a is 8.

So, Put b = 10 and a = 8;

⇒ b = ak

⇒ 10 = k × 8

⇒ k = 10 / 8

⇒ k = 5/4

So, When a is 9 and k is 5/4, then;

⇒ b = ak

⇒ b = 9 × 5/4

⇒ b = 45/4

Thus, The value of b = 45/4

Step-by-step explanation:

Answer:

0.9554

Step-by-step explanation:

d = 4

r = d/2

r = 4/2

r = 2

V = 12

V = pi r^2 h

V = 3.14 * 2^2 * h

12 = 3.14 * 4 * h

12 = 12.56 * h

h = 12 / 12.56

h = 0.9554

Answer:

y = 20 + 35x or y = 35x + 20

Step-by-step explanation:

Looking at the problem, a cell phone company charges $20 for a new account, and $35/month for phone service. With that information we can quickly form this equation:

y = 20 + 35x

The y is the total cost, 20 is the initial charge, and 35x is the per-month charge.

What is below is the graph for this equation.

Answer:

$11,00 x ( 100% + 20%) = $13.2 /h

Step-by-step explanation:

Answer:

x=10.247

y=52.02

z=37.98

Step-by-step explanation:

For x you use Pythagorean theorem which, in this situation would be 13^2=8^2+x^2 rearranging this we can figure out x by taking the square root of 13^2-8^2.

For y you can use any trig function but I chose to use cos since that uses info we're given, to find y you just do the inverse cos or cos^-1 of 8/13 to find the angle

For z you can use any trig function but I chose to use sin since that uses info we're given, to find z you just do the inverse sin or sin^-1 of 8/13 to find the angle

Answer:

AD = 230

Step-by-step explanation:

here, we want to find the measure it AD

To do this, we need the value of x firstly

To get this, we are going to use the trapezoid midpoint theorem

The theorem is that the sum of the two parallel sides of a trapezoid when divided by 2 will give the middle point length of the trapezoid

Applying this:

1/2{30x-10+ 30x + 28} = 31x + 1

2(31x + 1) = 60x+ 18

divide both sides by 2

31x + 1 = 30x + 9

31x -30x = 9-1

x = 8

But;

AD = 30x-10

AD = 30(8)-10

AD = 240-10

AD = 230

Answer: B, 2×c×d

Step-by-step explanation:

When numbers and letters are next to each other in algebra it means times. So, 2cd means 2×c×d.

Answer:

add a point 4 units to the left

Step-by-step explanation:

Answer:

Add a point 5.5 units right of 1

Step-by-step explanation:

I used a ruler, and found out that the distance between 0 and 1 is 1cm.  The distance between 0 and x is 2.5cm.  Since x is to the left of 0, x = 2.5.

4 - -2.5 = 4 + 2.5 = 6.5, or 6.5 units right of 0, which is the same as 5.5 units right of 1.
