The <em>correct answer</em> is:

False.

Explanation:

While vertical angles are congruent, this does not mean that <em>all</em> congruent angles must be vertical angles. Other types of angles are congruent as well; for example, alternate interior angles are congruent; alternate exterior angles are congruent; corresponding angles are congruent; etc.

This statement is false as all vertical angles are considered congruent but not all congruent angles are considered vertical angles. Any obtuse or acute angle may be considered congruent. If the angle from point A to B is 110 and the angle between B to C is 110 as well then they are congruent

Original price of a CD is $17.50 discount is 50%​
ladessa [460]

Answer:

$8.75

Step-by-step explanation:

To calculate this you could use two methods. The first method is to find out what 10% is and multiply it by 5. The second method is to calculate 50% using the formula.

<u>Method 1:</u>

To work this out you would simply divide 17.50 by 10, which is 1.75. This is because percentages are out of 100 and so by dividing by 10 we are finding out what 10% is. Then you would multiply 1.75 by 5, which is 8.75. Then you would minus 8.75 from 17.50, which is 8.75.

<u></u>

1) Divide 17.50 by 10.

17.50/10=1.75

2) Multiply 1.75 by 5.

1.75*5=8.75

3) Minus 8.75 from 17.50.

17.50-8.75=8.75

4) The new price is $8.75

<u>Method 2:</u>

<u></u>

The formula for percentages is.

\frac{percentage}{100} * amount

<u></u>

To work this out you would first divide 50 by 100, which gives you 0.5. Then you would multiply 0.5 by 17.50, which is 8.75. Then you would minus 8.75 from 17.50, which is 8.75.

1) Divide 50 by 100.

50/100=0.5

2) Multiply 0.5 by 17.50.

17.50*0.5=8.75

3) Minus 8.75 from 17.50.

17.50-8.75=8.75

4) The new price is $8.75.

A standard American Eskimo dog has a mean weight of 30 pounds with a standard deviation of 2 pounds. Assuming the weights of sta
lions [1.4K]

Answer:

Approximately 24–36 pounds

Step-by-step explanation:

Given:

Weight of standard American Eskimo dog has mean= 30 pounds

A standard deviation= 2 pounds

For 99.7% of the dogs according to normal distribution would lie between 3 standard deviations on either side of the mean.

i.e. lower bound= Mean- 3 (standard deviation)

= 30-3(2)

=30-6

=24

Upper bound = Mean +3 (standard deviation)

= 30+3(2)

=30+6

=36

Hence the range of weights : 24-36 pounds

correct answer Approximately 24–36 pounds!
