Given: △ABC, E∈ AB m∠ABC=m∠ACE AB=34, AC=20 Find: AE

Mathematics

LenaWriter [7]3 years ago

Answer:

AE = 11.76 units

Step-by-step explanation:

For better understanding of the solution, see the attached figure :

Given : E ∈ AB, m∠ABC = m∠ACE, AB = 34 and AC = 20

To find AE :

In ΔABC and ΔACE,

m∠ABC = m∠ACE ( Given )

∠A = ∠A    ( Common angle for both the triangles )

By AA postulate of similarity of triangles, ΔABC ~ ΔACE

So, proportion of the corresponding will be equal.

\implies \frac{AC}{AB}=\frac{CE}{BC}=\frac{AE}{AC}\\\\\implies\frac{AC}{AB}=\frac{AE}{AC}\\\\\implies\frac{20}{34}=\frac{AE}{20}\\\\\implies AE=\frac{20\times 20}{34}\approx 11.76

Hence, AE = 11.76 units

Dakota makes a salad dressing by combining 6 1/3 fluid ounces of oil and 2 3/8 fluid ounces of vinegar in a jar. She then pours
k0ka [10]
We'll start by figuring out how many ounces of dressing she puts into the jar. To add together two mixed numbers with different denominators, we'll first find equivalent fractions with common denominators. 

The two fractions are \frac{1}{3} and \frac{3}{8}. The least common denominator of 3 and 8 is 24. Let's find equivalent fractions that have 24 as the denominator for both.
For \frac{1}{3}, \frac{1x8}{3x8} = \frac{3}{24}
For \frac{3}{8}, \frac{3x3}{8x3} = \frac{9}{24}

Now we can add the whole numbers and equivalent fractions together.
   6 \frac{3}{24}
+ 2 \frac{9}{24}
= 8 \frac{12}{24}
Reduce the fraction \frac{12}{24} by dividing the numerator and denominator by 12 to get the total dressing amount of 8 \frac{1}{2}.

Now we need to take the amount of dressing and subtract the amount that she poured out. The process will be the same as above, but we'll subtract instead of add. First, we'll find equivalent fractions using the common denominator 4.
Dressing \frac{1}{2} = \frac{2}{4}
Poured out \frac{1}{4} (This can stay the same since the denomiator is already 4.

Now we can subtract:
  8 \frac{2}{4}
- 2 \frac{1}{4}
= 6 \frac{1}{4}

The amount of dressing left in the jar is 6 \frac{1}{4} fluid ounces.

Find the y-intercept of the line: 9x + 3y = -18
uysha [10]

Answer:

(0,-6)

Step-by-step explanation:

9x + 3y = -18

Solve for y to get equation in slope intercept form

( y = mx + b )

9x + 3y = -18

Subtract 9x from both sides

9x - 9x + 3y = -18 - 9x

3y = -9x - 18

Divide both sides by 3

3y/3 = y

-9x - 18 / 3 = -3x - 6

We're left with y = -3x - 6

The equation is now in y intercept form

y = mx + b where b = y intercept

-6 takes the spot of b therefore the y intercept would be at (0,-6)

Factor 200t+8t^3-80t^2
valina [46]

Answer:

8t(t - 5)^2

Step-by-step explanation:

I would immediately rearrange these terms in descending order by powers of t:

8t^3 - 80t^2 + 200t

Then I'd factor out 8t:

8t(t^2 - 10 t + 25).

Finally, I'd factor the quadratic t^2 - 10 t + 25:

(t - 5)^2

and so 200t+8t^3-80t^2 in factored form is 8t(t - 5)^2.
