Answer:
1) triangles are similar
Step-by-step explanation:
The height from vertex X of isosceles ∆WXY is 4 units. The width WY is also 4 units. In isosceles ∆UVW, the height from vertex V is 6 units, and the width UW is also 6 units.
The height ratios are ...
∆WXY/∆UVW = 4/6
The width ratios are ...
∆WXY/∆UVW = 4/6
The measures of ∆WXY are proportional to those of ∆UVW, so the triangles are similar.

Strictly speaking, you cannot go by triangle height and width alone. That is why we made not of the fact that the triangles are <em>isosceles</em>. When base and height of an isosceles triangle are proportional, the Pythagorean theorem guarantees that side lengths are proportional. Trigonometry can also be invoked to support the claim that angles are congruent.
Answer:
Step-by-step explanation:
Find the number of possible 5-card hands that contain the cards specified. The cards are taken from a standard 52-card deck.
5 red cards.
Ans: 26C5 = 26!/[21!*5!] = 65780
--------------------------------------------
4 spades and 1 card that is not a spade.
Ans: [13C4*39C1] = 27885
--------------------------------------------
3 face cards (kings, queens, or jacks) and 2 cards that are not face cards.
Ans: 12C3*40C2 = 171,600

Answer:
Step-by-step explanation:
for this equation
d=st
we can represent s as d/t
we can represent t as d/s
and in real world we have a lot of this type of equations
some of them are,
d=m/v ( density = mass / volume )
C = m.c ( heat capacity = mass x specific heat )
Answer:
1/2.
Step-by-step explanation:
The slope = rise/run
= (-13 - (-10)) / (3 - 9)
= -3 / - 6
= 1/2.
The answer is 18 ft because 36 divided by 2 is 18
