The following triple represents the side lengths of a triangle. Determine whether the triangle is a 45-45-90 triangle, a 30-60-90 triangle, or neither.2, 1, 2squared3.

Answer Choices:
a.
45-45-90 triangle
c.
neither
b.
30-60-90 triangle

Answers

If the sides of the triangle have lengths of: 2, 1, and 2√3

Then, the triangle is a

c. neither a 45-45-90 triangle nor a 30-60-90 triangle.

Looking at the lengths, if the triangle is a right triangle
2 and 1 must be the measure of the legs
2√3, the measure of the hypotenuse

If we use the Pythagorean theorem,
2^2 + 1^2 = (2√3)^2
5 = 12 (not correct)

Therefore, the triangle is not a right trangle

six girls and four boys have entered the science fair. first, second, and third place awards are to be given out. what is the probability that exactly one girl and two boys will recite awards? express your answer as a percent

Answers

The probability that exactly one girl and two boys will recite awards is 10%.

Probability

Given:

6 girls +4 boys

Hence:

Probability of a girl getting the first place =6/10

Probability of a boy getting the second place=4/9

Probability of a boy getting the third place=3/8

Total probability:

Total probability=6/10×4/9×3/8

Total probability=0.1×100

Total probability=10%

Therefore the probability that exactly one girl and two boys will recite awards is 10%.

Answer:

6:9:15

Step-by-step explanation:

multiply each number in the first ratio by three. They multiplied 3 times three to get 9, so you have to do that to each number to make it a ratio.

A ratio is like an equivalent fraction. It all has to be proportionate to the other fraction.

Examples:

4:3 is equal to 8:6

16:6 is equal to 32:12

Answer: 6 :9:15

Step-by-step explanation:

What number would complete the pattern below? 16 4 12 36 9 27 44 11 __

Answers

The answer to this question is 33. Within the sequence are pairs of numbers, and each pair is separated by the resultant figure when they are subtracted from one another. So, 16 - 12 = 4 36 - 27 = 9, and 44 - 33 = 11. Hope that solves the question for you!

To solve this problem, you must understand what is the Common Denominator Rule:

The Common Denominator rule is when you use the common factors of the denominators to make them the same number. This will allow you to add and subtract fractions.

First, let’s put these two mixed fractions as improper fractions. Learn more about making that conversion here: brainly.com/question/35061276

$(23)/(4)$

$(-19)/(6)$

Now that you have your fractions, look at the denominators: 6 and 4.

A common factor between 4 and 6 is the number 12. Multiply the denominators and numerators of each fraction by the number that will turn the denominator into 12:

$((23)(3))/((4)(3))$ = $(69)/(12)$
