Is this right? If not let me know and explain how if u can. (No link <3)

Answer:

9/35

Step-by-step explanation:

There are a total of 15 bulbs to choose from randomly. First a new bulb is chosen. Chance is 9/15 because 9 out of 15 are new.

Then there are only 14 bulbs left. Then a used bulb is chosen. Chance is 6/14 since 6 out of remaining 14 are used.

Total chance for this to happen is 9/15 * 6/14 = 54/210 = 9/35.

15. A seal dives to a depth of – 3/4 mile below the surface of the water. A penguin’s depth is 1/3 as deep as the seal’s depth.

I think it may be 1/4, but I am not sure. I just multiplied them and got that answer.

Two isosceles triangles share the same base. Prove that the medians to this base are collinear. (There are two cases in this pro

Anna71 [15]

Answer:

Given: Two Isosceles triangle ABC and Δ PBC having same base BC. AD is the median of Δ ABC and PD is the median of Δ PBC.

To prove: Point A,D,P are collinear.

Proof:

→Case 1. When vertices A and P are opposite side of Base BC.

In Δ ABD and Δ ACD

AB= AC [Given]

AD is common.

BD=DC [median of a triangle divides the side in two equal parts]

Δ ABD ≅Δ ACD [SSS]

∠1=∠2 [CPCT].........................(1)

Similarly, Δ PBD ≅ Δ PCD [By SSS]

∠ 3 = ∠4 [CPCT].................(2)

But, ∠1+∠2+ ∠ 3 + ∠4 =360° [At a point angle formed is 360°]

2 ∠2 + 2∠ 4=360° [using (1) and (2)]

∠2 + ∠ 4=180°

But ,∠2 and ∠ 4 forms a linear pair i.e Point D is common point of intersection of median AD and PD of ΔABC and ΔPBC respectively.

So, point A, D, P lies on a line.

CASE 2.

When ΔABC and ΔPBC lie on same side of Base BC.

In ΔPBD and ΔPCD

PB=PC[given]

PD is common.

BD =DC [Median of a triangle divides the side in two equal parts]

ΔPBD ≅ ΔPCD [SSS]

∠PDB=∠PDC [CPCT]

Similarly, By proving ΔADB≅ΔADC we will get, ∠ADB=∠ADC[CPCT]

As PD and AD are medians to same base BC of ΔPBC and ΔABC.

∴ P,A,D lie on a line i.e they are collinear.

Are the only bases that I need to use 2 and 4 along with the height 2.5 and I just ignore the 3?

vaieri [72.5K]

Answer:

$7.5\ units^2$

Step-by-step explanation:

The formula to find the area of a trapezoid is the following,

$A=(h)(\frac{(b_1)+(b_2)}{2})$

Where ( $h$ ) represents the heights of the trapezoid, ( $b_1$ ) and ( $b_2$ ) represent the bases of the trapezoid, or rather the two parallel sides of the trapezoid.

One is given all of these values in the picture,

$h = 2.5\\\\b_1 = 2\\\\b_2 = 4$

Substitute these values into the formula and solve for the area of the trapezoid,

$A=(2.5)(\frac{(2)+(4)}{2})$

Simplify,

$=(2.5)(\frac{6}{2})\\=(2.5)(3)\\=7.5$
