Answer:

x = 52°

Step-by-step explanation:

I have attached an image to depict the given angles.

From the attached image, we can see that the unknown angle is x°.

Thus, since that corner is 90°, then;

x + 38 = 90

Subtract 38 from both sides to get;

x = 90 - 38

x = 52°

Which of the following is the inverse y=3x
Nitella [24]
To find an inverse, switch the x and the y and solve for the new y.  Yours switched is x = 3y.  Now solving for y we divide both sides by 3 to get y = x/3

Which set of coefficients of the terms in the expansion of the binomial (x+y)^3 is correct ?
BigorU [14]
We are technically FOILing this out... with a power of 3.

(x+y)(x+y)(x+y)

So we can first factor out the first two "x+y"s.

( x^{2} +2xy + y^{2} ), multiplied by the last "x+y".

x^{3} +3 x^{2} y +3x y^{2} + y^{3}

Coefficients are the number that comes in front of a variable. 

In this case, 1 comes in front of x^{3}, 3 comes in front of x^{2} y, 3 comes in front of x y^{2}, and 1 comes in front of y^{3}.

Thus: 1, 3, 3, 1.

The punch bowl at felicia's party is getting low so she adds 12 cups of punch to the bowl two guests serve themselves 1.25 cups
Eduardwww [97]

2.75 cups were in the punch bowl before felicia refilled it .

<u>Step-by-step explanation:</u>

Here we have , the punch bowl at felicia's party is getting low so she adds 12 cups of punch to the bowl two guests serve themselves 1.25 cups and 2 cups and 2 cups of punch the punch bowl now contains 11.5 cups of punch . We need to find how many cups were in the punch bowl before felicia refilled it let n=number of cups bowl before felicia refilled it. Let's find out:

Initially we have , n number of cups of punch ! Than 12 additional cups were added , given below is the equation framed for the number of cups present:

⇒ n+12

Now , After this 1.25 and 2 cups were served by guests themselves and remaining cups were 11.5 i.e.

⇒ 11.5+1.25+2

⇒ 14.75

Equating both we get :

⇒ n+12=14.75

⇒ n=14.75-12

⇒ n=2.75

Therefore , 2.75 cups were in the punch bowl before felicia refilled it .
