Answer:

The first option

Step-by-step explanation:

Hello!

We want to find the correct proportion. 26.40/220 is the correct proportion for the amount earned because the associate earned $26.40 out of $220. The term "out of" is division.

Now, we have to match the format, where the commissions are the numerator, and the total is the denominator.

So we have x in the numerator (the same as 26.40) and 515 in the denominator (the same as 220).

This would be the first option : \frac{26.40}{220} = \frac{x}{515}

What is the distance between the points (5,1) and (-3,-5)?<br>​
Charra [1.4K]

Answer

\boxed{10 \: \:  units}

Step by step explanation

Let the points be A and B

A ( 5 , 1 ) ⇒ ( x₁ , y₁ )

B ( -3 , -5 )⇒ ( x₂ , y₂ )

Now, let's find the distance between theses two points:

Distance = \mathsf{ \sqrt{ {(x2 - x1)}^{2} +  {(y2 - y1)}^{2}  } }

Plug the values

\mathsf{ \sqrt{ {( - 3 - 5)}^{2} +  {( - 5 - 1)}^{2}  } }

Calculate

\mathsf{ \sqrt{ { ( - 8)}^{2}  +  {( - 6)}^{2} } }

Evaluate the power

\mathsf{ \sqrt{64 + 36} }

Add the numbers

\mathsf{ \sqrt{100} }

Write the number in exponential form with a base of 10

\mathsf  {\sqrt{ {10}^{2} } }

Reduce the index of the radical and exponent with 2

\mathsf{10 \: units}

-------------------------------------------------------------------------------

The distance formula is used to determine the distance ( d ) between two points. If the co-ordinates of the two points are ( x₁ , y₁) and ( x₂ , y₂ ) , the distance equals the square root of x₂ - x₁ squared + y₂ - y₁ squared.

Hope I helped!

Best regards!

X and y are two positive numbers and y is three greater than x. the product of the numbers is 130. find the smaller number, x.
blagie [28]
Xy=130
y=3+x

x(3+x)=130
x²+3x-130=0
(x+13)(x-10)=0
x= -13 or 10

since the question says X and Y are positive we just dismiss-13

x=10
and y=13

Makovka662 [10]

Answer:

Molecules in both the metal and the surrounding air will start moving at lower speeds?

Step-by-step explanation:

I'm not sure this is the right answer, because i thought that the air and the metal would be in equilibrium.

So sorry if this is wrong, chemistry isn't my strongest subject.
