Answer:

ASA

Step-by-step explanation:

They give us one pair of angles and one pair of congruent sides for it to be ASA we need an additional angle but on the other side from where the last angle was. By vertical angles proof we can see that the angles at the intersection will be congruent so you have one angle then a side then another angle

Hope This Helps :)

A hotel claims that 8585% of its customers are very satisfied with its service. complete parts a through d below based on a ran

We can solve this problem using the binomial distribution. A binomial distribution<span> can be thought of as a success or failure outcome in an experiment or survey that is repeated multiple times.
</span>Probability function of binomial distribution has the following form:
$P= \frac{n!}{k!(n-k)!} p^k(1-p)^{n-k}$
p represents the probability of each choice we want. k is the number of choices we want and n is the total number of choices.
In our case p=0.85, k=5 and n=6.
We can now calculate the answer:
$P= \frac{6!}{5!(6-5)!} 0.85^5(1-0.85)^{6-5}=0.39$
The probability is 39%.

A right-angled triangle has one side of length 1.5 cm. Its hypotenuse is 6 cm. How long is its other side?

irga5000 [103]

Answer:

Step-by-step explanation:

pythagorean theorem. a^2+b^2=c^2

1.5^2+b^2=6^2

2.25+b^2=12

12-2.25=b^2

b^2=9.75

take the square root

b=3.12

A raindrop was 24 meters above the ground, falling straight down at a constant velocity. It took the raindrop 3 seconds to fall

lina2011 [118]

Answer:

4 m/s downwards

Step-by-step explanation:

Velocity is given by dividing the distance by time taken to cover the diatance. Therefore, expressed as v=d/t

The distance is given as 24 m but the time given covers only half the distance. Therefore, the distance is 0.5*21=12 m

Time taken is given as 3 s

Substituting 12 m for d and 3 s for t then

V=12/3= 4 m/s

Velocity must have direction component hence velocity is 4 m/s downwards
