Answer:

A: SSS | B: HL | C: SAS

Step-by-step explanation:

Firstly, SSS is where you know that each side of a triangle is congruent to the other triangle.

Secondly, SAS is where you know two sides and an angle are congruent. This angle will be between two sides that are congruent. This can be put clockwise or counterclockwise, but the sides and angle must be consecutive.

Thirdly, AAS is where you know two angles and one side are congruent.

Lastly, HL (Theorem) is where you know that the hypotenuse and a leg of a right triangle are congruent.

A: TU≅WX, ST≅XV, and SU≅VW

B: Two right triangles; HA and OK are the hypotenuses, and HA≅OK, RH≅RK

C: ZW≅YX, ∠W≅∠X, and WX≅WX

An elevator descends into mine shaft at the rate of 6m/min. If the descend starts from 10m above the ground level , how long wil

AnnyKZ [126]

Answer: Hi!

So first, I'm going to convert "350 below ground level" to -350, as this is what "below ground level" represents.

Now, we should find the total distance traveled. Take the absolute value of -350 (350) and add it to 10, the metres above ground level. This is 360.

We already know the rate of travel; 6m/min. All we have to do now is divide the total distance (360) by the rate of travel (6)!

360 ÷ 6 = 60

So, it took 60 minutes, or one hour, for the elevator to travel down the shaft!

Hope this helps!

the number of ants per acre in the forest is normally distributed with mean 42000 and standard deviation 12275. let x = number o

saul85 [17]

Answer:

0.3182 = 32.81% probability that a randomly selected acre has between 32647 and 43559 ants.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 42000, \sigma = 12275$
