Answer:  The correct option is (B) 1\dfrac{1}{2}.

Step-by-step explanation:  Given that Alice had 4\dfrac{1}{4} pounds of walnuts at the beginning of the week. At the end of the week, she had 2\dfrac{3}{4} pounds.

We are to find the quantity of walnuts that she had used.

We have

The quantity of walnuts that Alice has is

q_1=4\dfrac{1}{4}=\dfrac{17}{4}~\textup{pounds}

and the quantity of walnut that she had at the end of the week is

q_2=2\dfrac{3}{4}=\dfrac{11}{4}~\textup{pounds}.

Therefore, the quantity of walnut that she has used is given by

Q=q_1-q_2=\dfrac{17}{4}-\dfrac{11}{4}=\dfrac{6}{4}=\dfrac{3}{2}=1\dfrac{1}{2}.

Thus, the required quantity of walnut that she has used is 1\dfrac{1}{2}~\textup{pounds}.

Option (B) is CORRECT.

Find the length of the third side to the nearest tenth.
Aliun [14]

Answer:

5.3

Step-by-step explanation:

You use the Pythagoras theorem which is a^2+b^2=c^2.

Since you're solving for a side length that's not the hypotenuse you will manipulate the equation to c^2-a^2=b^2. From here you just plug in numbers.

8^2 - 6^2 = b^2

64 - 36 = b^2

b = sqrt(28)

b = 5.2915.... = 5.3

Drupady [299]
For the answer to the question above asking to f<span>ind the coordinates of Z without using any new variables. 
</span>

Vector WZ equals vector VP, which is (p, -q) 
So Z is (-p - r + p, q - q) which is (-r, 0)

A plant can manufacture 50 golf clubs per
Mazyrski [523]

Answer:

The correct equation is "y=30x+6147". A further explanation is given below.

Step-by-step explanation:

The given values are:

(x1, y1) = (50, 7647)

(x2, y2) = (100, 9147)

As we know,

The slope is,

⇒ m=\frac{y2-y1}{x2-x1}

On substituting the given values, we get

⇒     =\frac{9147-7642}{100-50}

⇒     =\frac{1500}{50}

⇒     =30

Now,

⇒ (y-y1)=m(x-x1)

On substituting the given values in the above equation, we get

⇒ y-7647=30(x-50)

⇒ y-7647=30x-1500

On adding "7647" both sides, we get

⇒ y-7647+7647=30x-1500+7647

⇒                        y=30x+6147
