Answer:

41.9m Or maybe 41.1m.

Step-by-step explanation:

It works with subtraction and a lil bit of addition.

0.5 + 0.4 = 0.9. Or maybe 0.5 - 0.4 = 0.1?

31 + 10 = 41.

So the answer is 41.9m

Your question is incomplete; However, a similar question is:

If B is between A and C, AB = x, BC = 2x + 2, and AC = 14, find the value of x. Then find AB and BC.

This should serve as a guide

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]AB = x[/tex]

[tex]BC = 2x + 2[/tex]

[tex]AC =14[/tex]

Required

Determine x, AB and BC.

Since B is between A and C;

[tex]AB + BC = AC[/tex]

Substitute x for AB; 2x + 2 for BC and 14 for AC

[tex]x + 2x + 2 = 14[/tex]

[tex]3x + 2 = 14[/tex]

Collect Like Terms

[tex]3x = 14 - 2[/tex]

[tex]3x = 12[/tex]'

[tex]x = \frac{12}{3}[/tex]

[tex]x = 4[/tex]

Substitute 4 for x in

[tex]AB = x[/tex]

[tex]BC = 2x + 2[/tex]

[tex]AB = 4[/tex]

[tex]BC = 2(4) + 2[/tex]

[tex]BC = 8 + 2[/tex]

[tex]BC = 10[/tex]

Answer:

x=3.3

P = 60

Step-by-step explanation:

The perimeter of the square is

P = 4s

   = 4(7x-8.1)

    =28x -32.4

The perimeter of the equilateral triangle is

P = 3s

   = 3(10x-13)

    =30x-39

The perimeters are equal

28x -32.4 = 30x-39

Subtract 28x from each side

28x-28x -32.4 = 30x-28x-39

-32.4 = 2x-39

Add 39 to each side

-32.4 +39 = 2x-39+39

6.6 = 2x

Divide by 2

6.6/2 = 2x/2

3.3 =x

The perimeter is

30x-39 = 30*3.3 -39 = 99-39 = 60

Answer:

The final outside temperature = -6°

Step-by-step explanation:

GIven that :

the outside temperature = -13°

The temperature drops by 9°

But then increases by 16°.

The final temperature can be expressed as:

the outside temperature - temperature drop

= -( 13° - 9°)

= - 22°

it is said that the temperature later increase by 16°

∴  - 22° + 16°

= -6°

The final outside temperature = -6°

Answer:

16

Step-by-step explanation:

A direct variation equation has the following format:

[tex]y=kx[/tex]

Where k is the constant of proportionality.

Therefore, we want to find k.

We know that when x=5, y=8. Substitute the values:

[tex]8=5k[/tex]

Divide both sides by 5:

[tex]k=\frac{8}{5}[/tex]

Thus, the constant of proportionality is 8/5 or 1.6. So, our equation is:

[tex]y=\frac{8}5x[/tex]

To find y when x is 10, plug in 10:

[tex]y=\frac{8}{5}(10)\\y=80/5=16[/tex]

Thus, y is 16.

Answer:

Step-by-step explanation:

2kg/m² convert to g/100cm²

1 kg=1000 g

2kg=  ???

2*1000=2000kg

m      ⇒      100cm

m²     ⇒      10000 cm²

2kg/m²=2*1000/(10000/100) cm²

=2000/100 cm²

250*1000=250000

1 hectare=10000 m²

250000/10000 g/m²

Step-by-step explanation:

The price per pound is the cost of the item divided by its weight in pounds.

This refers to the value of a good or a product that has some monetary value.

We should note that if the weight was given (inpounds), then it would be easy to find the price per pound by dividing its weight in pounds.

Answer:

Height = 18.2 inches

Step-by-step explanation:

15 gallons = 3,465 cubic inches

Length of the rectangular prism = 20 inches

Width of the rectangular prism = 10 inches

Height of the rectangular prism = x inches

Volume of the rectangular prism = 3,645 cubic inches

Volume of the rectangular prism = length × width × height

3,645 = 20 × 10 × x

3,645 = 200x

Divide both sides by 200

3,645 / 200 = x

18.225 = x

To the nearest tenth of an inch

x= 18.2 inches

Therefore,

The rectangular prism is 18.2 inches high

Answer:

6 ft

Step-by-step explanation:

The length is (3 × width) + 6,

And the length is 24

If you take 6 away from the length, it will be 18, because 24 - 6 = 18

And then the length is also 3× the width (+6 - we've already done this part) so if you divide 18 by 3 you will get 6 ft as the answer

A parallelogram is a quadrilateral consisting of pairs of parallel sides.

The angle can be defined as the one line inclined over another line.

Here,
In the parallelogram,
The sum of the adjacent angle is 180°.
Thus,
x + 130 = 180
x = 180 - 130
x = 50°
