Answer:
<h3>AC=96 units.</h3>
Step-by-step explanation:
We are given a parallelogram ABCD with diagonals AC and BD intersect at point E.
, and CE=6x .
<em>Note: The diagonals of a parallelogram intersects at mid-point.</em>
Therefore, AE = EC.
Plugging expressions for AE and EC, we get
Subtracting 6x from both sides, we get
Factoriong quadratic by product sum rule.
We need to find the factors of -16 that add upto -6.
-16 has factors -8 and +2 that add upto -6.
Therefore, factor of quadratic is (x-8)(x+2)=0
Setting each factor equal to 0 and solve for x.
x-8=0 => x=8
x+2=0 => x=-2.
We can't take x=-2 as it's a negative number.
Therefore, plugging x=8 in EC =6x, we get
EC = 6(8) = 48.
<h3>AC = AE + EC = 48+48 =96 units.</h3>
<u>I'm assuming you're formula is "</u><span><u>C=a/(a+12)*A" as that is only logical</u></span><span>
You get the formula </span><u>"C=a/(a+12)*A"
</u>You insert the numbers given, in place of the letters given.
<u>
</u>C=6/(6+12)*180
<u />C=3*180
C=540 mg
Which is of course wrong because it is more than the adults dosage. What i'm trying to say is "Your formula is incorrect , follow the steps I gave, but use the correct formula"
It would be 48/64 this is done by finding how many times 4 fits in 64 (64/4) then multiplying 3 by that answer
Answer:
C
Step-by-step explanation:
You can plug in each combination to see what would work
C is the only combination that satisfies all the constraints: it earns him more than $800 and is less than 120 plates.
Answer:
Part 1) The value of y=6
Part 2) ED=36, DB=36 and EB=72
Step-by-step explanation:
In this problem we know that
ED=DB -----> equation A
EB=ED+DB -----> equation B
The point D is the midpoint ED
see the attached figure to better understand the problem
step 1
Find the value of y
Substitute the given values in the equation A
solve for y
step 2
Find the value of ED,DB and EB
substitute the value of y
Remember that
ED=DB
therefore
Find the value of EB
EB=ED+DB
