Answer:

I’m not sure what the height or the width is, or the perimeter, I’m not sure if it’s a prism, but it should be 1.7 ?

Step-by-step explanation:

In isosceles △ABC the segment BD (with D∈ AC ) is the median to the base AC . Find BD, if the perimeter of △ABC is 50m, and the

Morgarella [4.7K]

Let the equal sides of the isosceles Δ ABC be x.

Given that the perimeter of Δ ABC = 50m.

Therefore, 2x + AC = 50 --- (1)

It is also given that the perimeter of Δ ABD = 40m.

Therefore, x + BD + AD = 40

BD is the median of the Δ ABC. Therefore, D is the midpoint of AC.

So AD = CD.

Or, AD = $\frac{1}{2}$ AC

Therefore, $x + BD + \frac{1}{2} AC = 40$

Multiply both sides by 2.

2x + 2BD + AC = 80

From (1), 2x + AC = 50.

Therefore, 2BD + 50 = 80

2BD = 80 - 50

2BD = 30

BD = 15m.

100 Points!!!!!!!!!! please hurry with full explanation of how you got the answer if not i guess thats okay just an asnwer will

kaheart [24]

Here, Alicia is wrong because on evaluating $3 ^{1.4}$ we get $4.65554$ which is of course less than 6. Zara's calculation could be;

$3 ^{1.4} \\ \\ 3 ^{ \frac{7}{5} } \\ \\ \sqrt[5]{3 ^{7} } \\ \\ 3 \sqrt[5]{3 ^{2} } \\ \\ 3 \sqrt[5]{9} \\ \\ = 4.6554$

<h3>Final answer:-</h3>

Zara's calculations are correct and alicia's calculations are wrong.
