Bottled water and medical supplies are to be shipped to victims of a hurricane by plane. Each plane can carry 90,000 pounds and
Kaylis [27]

Answer:4000 bottle containers and 1000

Medical kits

Step-by-step explanation:

The total weights the plane can take per trip is 90000lb. It implies that if we multiply the weight of each bottle container by the number of bottle container and add it to the product of the number medical kit and the weight of each medical kit, we will obtain a total weight of 90000lb.

If x is the number of bottle and y is the number of medical kit

20×x+10×y=90000....i

Also

The total volume the plane can take per trip is 6000ft³ It implies that if we multiply the volume of each bottle container by the number of bottle container and add it to the product of the number medical kit and the volume of each medical kit, we will obtain a total volume of 6000ft³.

Recall, x is the number of bottle and y is the number of medical kit

1×x+2×y=6000....ii

Combining equation i and ii and solving simultaneously,

x=4000 units and y= 1000 units in each plane trip

BRAINLIEST WILL BE AWARDED TO THE FIRST CORRECT ANSWER!
defon

Answer:

Assuming (6 9) is a fraction I just multipled the coordinates of A,B,C,D by that

Step-by-step explanation:

Example: A coordinates are (-5,-2) so I multiplied -5 by 6/9 which is -10/3, and -2 by 6/9 which is -4/3.

I then plotted (-10/3,-4/3), which would be A'

Do the same for the rest of BCD to find B'C'D'

So, its time to do some MATH!

ok so i would first approach this problem by placing the prices in order from least to greatest......um it would look something like this...(cue the math skills in my brain)

1.29,1.59,1.99,2..09, and last but most definitely not least (get it?) 2.19

so basically the median is like the MIDDLE number of your data (shout out to my fellow middle children!)

and so you may be asking "how does one figure this out?" and i will tell you that it is quite simple...

so what you got to do is cross out a number from the left and a number from the right, and you will be left with one number, which is your middle number (or in fancy maths language -the median- that was supposed to be said with a British accent, so just bear with me there :-))

and so your final answer should be....(drumroll please)

$1.99 is your median 

(ta- da you are supermathematicalgeniuslevel smart)

-4(1.75 + 1x) = 18

1.75 + 1x = 18/-4

1.75 - 1.75 + x = -4.5 - 1.75

x = -6.25

Answer:  x = -6.25
