Answer:

10 euros

Step-by-step explanation:

1 euro=$1.31 so you take 1.31 and multiply by 9 to get 11.79 which is too low even after rounding, but if you multiply by 10 you will get 13.1, you will have too much even after rounding down but you would get change

Answer:

13. >  14.  <  15. 367 to the 4th power  16. 3 to the -6

Step-by-step explanation:

Answer:

15/16

Step-by-step explanation:

because 21/24 reduces to 7/8

35/40 reduces to 7/8

15/16 doesn't reduce to anything so it stays 15/16

28/32 reduces to 7/8

Therefore your answer is 15/16

The question is incomplete, the complete question is;

In physics, the Ideal Gas Law describes the relationship among the pressure, volume, and temperature of a gas sample. This law is represented by the formula PV = nRT, where P is the pressure, V is the volume, T is the temperature, n is the amount of gas, and R is a physical constant. Which of the equations below are equivalent to the formula PV = nRT? Select all that apply. A. P = VnRT B. V = nRT/P C. n = PV/RT D. R = PVnT E. T = nR/PV

Answer:

B. V = nRT/P

n = PV/RT

Step-by-step explanation:

The equation PV=nRT is called the ideal gas equation. If we make V the subject of the formula, then we have; V = nRT/P

Similarly, if we make n the subject of the formula we have n = PV/RT.

These two equations are equivalent to the original equation PV=nRT

Answer:

Any of the steps below could be similar equations.

Step-by-step explanation:

2(x + 3) - 2 = 16

~Simplify

2x + 6 - 2 = 16

~Combine like terms

2x + 4 = 16

~Subtract 4 to both sides

2x = 12

~Divide 2 to both sides

x = 6

Best of Luck!

Answer:

-5 + 4x

Step-by-step explanation:

-(5-4x)

Distribute the negative sign to each term in the parentheses

-5 -  -4x

-5 + 4x

Answer:

[tex]\huge\boxed{\sf{-5+4x}}[/tex]

Step-by-step explanation:

Hello.

First, think of the minus sign as being -1.

Now, multiply -1 times 5 and -4x.

-1 times 5 is -5

-1 times -4x is 4x

Put them together:

-5+4x (this expression can't be simplified anymore, because -5 and 4x aren't like terms)

And we're done!
I hope it helps & have an outstanding day!

This series follow above sequences.

So next term of this series,

= 32^2 + 1

= 1024 + 1

= 1025.

Answer:

the answer is 4.187

Step-by-step explanation:

you have to multiply the .79 times 5.3

Let w is the width of the strip mowed by the outer mower as shown in the figure. So, the area mowed by the outer mower is the area of the shaded region.

Each wants to mow no more than half of the lawn, so, both have to mow exactly half of the area of the lawn.

The length of the rectangular lawn, [tex]l=170[/tex] feet

and the width, [tex]b=95[/tex] feet.

The dimensions [tex]( l'\times b')[/tex] of the area left to the other mower are

[tex]l'=170-2w[/tex] and [tex]b'=95-2w[/tex].

As. both most have to mow half of the lawn, so

[tex](170-2w)\times(95-2w)=\frac{170\times95}{2}[/tex]

[tex]\Rightarrow 4w^2-530w+8075=0[/tex]

[tex]\Rightarrow w=17.5641, 114.9358[/tex]

Ignoring the higher value as w cant be more than the dimension of the lawn.

So, the required width of the strip

w=17.564 feet (rounded up to three decimal places)

As the outer mower has a 24-inch cut, so in 1st trip, he cuts the 24-inch or 2 feet of required width.

So, the number of the required trip is

[tex]\frac{17.564}{2}=8.782[/tex]

=8.8 (rounded up to one decimal place)

Answer:

[tex]\boxed{-\frac{17}{40} }[/tex]

Step-by-step explanation:

Rewrite the decimal number as a fraction with 1 in the denominator.

Then

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000

And then....

Find the Greatest Common Factor (GCF) of 425 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 25.

Therefore x = -17/40

In conclusion, – 0.425 = -17/40

Answer:

2x-9

Step-by-step explanation:

Answer: ∠A = 65°

Step-by-step explanation:

All angles in a triangle add up to 180°.

Firstly, you need to solve for x.

Set all angles equal to 180°:

2x - 9 + 2x + 4 + x = 180

Combine like terms:

5x - 5 = 180

Add 5 to both sides:

5x = 185

Divide both sides by 5:

x = 37

Now, plug x into angle A:

∠A = 2(37) - 9

∠A = 74 - 9

∠A = 65°

Hope this helps!

Answer:

y= 1/2x+2

Step-by-step explanation:

First we need to find the slope

Pick two points on the line

(0,2) and (2,3)

Using the slope formula

m = ( y2-y1)/(x2-x1)

   = ( 3-2)/(2-0)

    = 1/2

We have the y intercept = 2

Then using the slope intercept

y = mx+b where m is the slope and b is the y intercept

y= 1/2x+2
