We know that
3 2/4  -------------> is (3*4+2)/4--------> 14/4-------> 7/2
2 2/3 --------------> is (2*3+2)/3--------> 8/3

if a new washing machine used 7/2 gallons of water ------------> one full load <span>cloths
</span> X gallons of water------------------------------------------------------> 8/3 of load cloths<span>
X=(8/3)*(7/2)---------> X=56/6------->28/3 gallons of water
28/3--------> 9 1/3 gallons of water

the answer is
 </span>9 1/3 gallons of water

In trapezoid ABCD with legs <br> AB<br> and <br> CD<br> , ACAD=23 dm^2. Find AABD.
Fed [463]

In the figure, ABCD is a trapezoid with legs AB and CD.

Join AC and BD.

For the triangle CAD, from the vertex C, draw an altitude CE and for the triangle ABD, from the vertex B, draw an altitude BF.

Clearly, CE = BF = h (say) --- (1)

Note that the base of the triangles CAD and ABD are the same and is AD.

It is given that ar(CAD) = 23dm^{2}.

Now, ar(ABD) =  \frac{1}{2}(AD)(BF)

= \frac{1}{2}(AD)(CE) from (1)

= ar(CAD)

= 23dm^{2}.

Hence, area of Δ ABD =  23dm^{2}..

Solve the following system of equations and show all work. y = −x2 + 4 y = 2x + 1
Aneli [31]

Answer:

x=3/4,y=5/2

Step-by-step explanation:

y=-x^2+4,y=2x+1

substitute y=-x^2+4 as y  for y=2x+1

2x+1=-x^2+4, x=3/4(isolate "x")

x=3/4

substitute x=3/4 for 2x+1=-x^2+4

y=2*3/4+1

y=5/2

x=3/4, y=5/2

hope this helps!

Describe two different strategies you could use to add l6 + 35 + 24 + 14.
adell [148]

Answer:

(16+35)+(24+14)

(16+14)+(35+24)

Step-by-step explanation:

This equation equals 89, basically what you would do is just add two numbers together and then add the sum of those two numbers, it makes the equation way easier to solve since you are not adding 4 numbers at a time, just 2.
