Could anyone help me with this problem? I understand that you can cross multiply but is there a shorter way?

There are several steps needed. I'm not sure this is what you call a shorter way, but I hope it helps!! :)

1) 3 lbs covers 1800 ft2 but we need to find how many ft2 1lb will cover. Divide # of lbs of seed available (3 lbs in this case) into the # of ft2 the available seed will cover (1800ft2 in this case):
1800ft2/3lbs=600ft2

So 1 lb covers 600ft2.

2) Now to find how many lbs 8400 needs. Divide the # of ft2 for 1 lb into the # of ft2 total (8400ft2 in this case):
8400/600ft2 (for 1lb) = 14 lbs

3) 14 lbs is now how many bags? The question does not say how many lbs in 1 bag.

IF ASSUMING the bags are 3lbs each, you divide the # of lbs per bag into the # of total lbs (14lbs in this case).

14lbs/3lb bags= 4.7 bags needed

IF 4lb bags:
14lbs/3lb bags= 3.5 bags needed

IF 5lb bags:
14lbs/5lb bags= 2.8 bags needed

IF 6lb bags:
14lbs/6lbs= 2.3 bags needed

Answer:

the number of vegetables did farmer bring in the market is 1764 vegetables

Step-by-step explanation:

The computation of the number of vegetables did farmer bring in the market is shown below:

= 18 bags × 42 kgs + 28 bags × 36 kgs  

= 756 + 1008

= 1764 vegetables

Hence, the number of vegetables did farmer bring in the market is 1764 vegetables

iogann1982 [59]

Answer:

XY=36\ units

Step-by-step explanation:

<u><em>The correct question is</em></u>

A, B, and C are midpoints of ∆XYZ. What is the length of XY

we know that

The<u><em> Midpoint Theorem</em></u> states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

step 1

Find the length of YZ

AB=\frac{1}{2}YZ

we have

AB=24\ units

substitute

24=\frac{1}{2}YZ

solve for YZ

YZ=48\ units

step 2

Find the length of XY

Applying Pythagoras Theorem in the right triangle XYZ

XZ^2=XY^2+YZ^2

substitute the given values

60^2=XY^2+48^2

solve for XY

3,600=XY^2+2,304

XY^2=3,600-2,304

XY^2=1,296

XY=36\ units

Applying the Midpoint Theorem

BC=\frac{1}{2}XY -----> BC=\frac{1}{2}(36)=18\ units

AC=\frac{1}{2}XZ -----> AC=\frac{1}{2}(60)=30\ units
