If you know the leg lengths of two right triangles.can you tell whether they are congruent?Explain your answer
Fofino [41]

Answer: the same length for one of the other two legs.

It doesn't matter which leg since the triangles could be rotated. If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.

To the nearest whole percent, what is the probability that a randomly chosen member of the JV swim team does not wear glasses an
Yuri [45]

Answer: 14%

Step-by-step explanation:

Complete question is provided in the attachment below:

Probability that members of the junior varsity swim team wear glasses = 55%=0.55

Given: P(wear glasses) = 0.55

P(not wear glasses) = 1-0.55 = 0.45

P(member in 10th grade | not wear glasses) = 30%

Using conditional probability formula:

P(B|A)=\dfrac{P(A\text{ and } B)}{P(A)}

\Rightarrow\ 0.30=\dfrac{P(\text{not wear glasses and in 10th grade})}{0.45}\\\\\Rightarrow\ P(\text{not wear glasses and in 10th grade})=0.45\times0.30\\\\0.135=13.5\%\approx14\%

Hence, the probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade = 14%.

So, the correct option is "14%".

A salesperson at a car dealership has a base salary of $25,000 per year and earns 5% commission on total sales.
Effectus [21]

So the person makes $50,000 minus the base salary of $25,000 which means he must make $25,000 in commissions.

So we have to figure out $25,000 is 5% of how much. There are many ways to do this.

5% is like saying 5/100. So $25,000 x 100/5 = $500,000

Or, to go from 5% to 100% you multiply by 20. Therefore your answer is $25,000 x 20= $500,000
