two friends share 1/4 gallon of lemonade equally. What fraction of the gallon of lemonade does each friend get?
Inga [223]
Since there are two people sharing 1/4 a gallon of lemonade, we need to divide 1/4 by 2:

1/4 / 2 = 1/8

Each friend gets 1/8 gallon of lemonade. 

Hope this helps!

OverLord2011 [107]

Answer:

1,Let us suppose that the height of the ladder is h and the horizontal distance of the ladder from the wall is d, then we use these two important trigonometric functions; the sine and the cosine.

h = sin 78 * 8 m and d = cos 78 * 8m where sin 78 = 0.9781 and cos 78 = 0.2079

With the given values, I expect you to do the two multiplications yourself. You will obtain a near to 8 m answer for the height h and a near to 1.7 m answer for the distance d.

2, The ship is 15 km from the port.

3,30m The ship must travel 15.6km 10 km 8. A rectangular field is 40 m long and 30 m wide. Carl walks from one corner of the field to the opposite corner along the edge of the field. Jade walks across the field diagonally to arrive at the same corner. Tip How much shorter is Jade's shortcut? Show your work. Sketch a diagram Carl-40m ade - b?= C² first. 40m. Jade = a't 62=(3 30' + 402 c 900 + 1,600 e? C² =2,5 U0 %3D C=/2500 C=50 10m shorter. jade shortcut is 172

maw [93]

Answer:

\dfrac{XY}{XZ} =\dfrac{5}{14}

Step-by-step explanation:

We are give the following in the question:

\dfrac{XY}{YZ} = \dfrac{5}{9}

We have to find the ration of the length of XY to the length XZ.

This, can be done as:

\dfrac{XY}{XZ} = \dfrac{XY}{XY+YZ}\\\\\Rightarrow \dfrac{XZ}{XY} = \dfrac{XY+YZ}{XY}  = 1 + \dfrac{YZ}{XY}\\\\\Rightarrow \dfrac{XZ}{XY} = 1+\dfrac{9}{5} = \dfrac{14}{5}\\\\\Rightarrow \dfrac{XY}{XZ} =\dfrac{5}{14}

Thus, the ration XY:XZ is 5:14
