A right triangle has a leg that is 2.70 m long and a hypotenuse that is 7.76 m long. What is the length of the other leg of the triangle in meters using the rules for significant digits?
Answers
Applying the Pythagorean Theorem and using the rules of significant digits, the length of the other leg of the right triangle is approximately 2.61 meters.
Recall:
Pythagorean Theorem is given as: \(a^2 + b^2 = c^2\)a and b are the two other legs of a right-angled triangle, while c is the hypotenuse.Using the Pythagorean Theorem, we are going to find the length of the other leg of the triangle that has:
a = 2.70 m (a leg)c = 7.76 m (hypotenuse)Substitute and find the value of b (the other leg).\(2.27^2 + b^2 = 7.76^2\\\\b = \sqrt{7.76^2 - 2.27^2} \\\\b = 2.607\)
Therefore, applying the Pythagorean Theorem and using the rules of significant digits, the length of the other leg of the right triangle is approximately 2.61 meters.

How many 11-card hands are possible with a 20-card deck?
Answers
There is only 1 possible 11-card hand that can be formed from a 20-card deck.
To determine the number of 11-card hands possible with a 20-card deck, we can use the concept of combinations.
The number of combinations, denoted as "nCk," represents the number of ways to choose k items from a set of n items without regard to the order. In this case, we want to find the number of 11-card hands from a 20-card deck.
The formula for combinations is:
nCk = n! / (k!(n-k)!)
Where "!" denotes the factorial of a number.
Substituting the values into the formula:
20C11 = 20! / (11!(20-11)!)
Simplifying further:
20C11 = 20! / (11! * 9!)
Now, let's calculate the factorial values:
20! = 20 * 19 * 18 * ... * 2 * 1
11! = 11 * 10 * 9 * ... * 2 * 1
9! = 9 * 8 * 7 * ... * 2 * 1
By canceling out common terms in the numerator and denominator, we get:
20C11 = (20 * 19 * 18 * ... * 12) / (11 * 10 * 9 * ... * 2 * 1)
Performing the multiplication:
20C11 = 39,916,800 / 39,916,800
Finally, the result simplifies to:
20C11 = 1
Consequently, with a 20-card deck, there is only one potential 11-card hand.

Emma has $140 cash to spend at a music store. How much can she spend on items if there is %7 sales tax?
Answers
Answer:
$130.84
Step-by-step explanation:
If a 7% sales tax is applied, the cost of the item (including tax) will be 107% of the original price.
To calculate how much Emma can spend if she has $140 cash to spend, divide $140 by 107%:
\(\implies \dfrac{140}{107\%}\)
\(\implies \dfrac{140}{\frac{107}{100}}\)
\(\implies 140 \times \dfrac{100}{107}\)
\(\implies \dfrac{14000}{107}\)
\(\implies 130.84\)
Therefore, Emma can spend $130.84 on items if there is a 7% sales tax.

Ten upright dominos of increasing height are lined up to be knocked down. The dominos are numbered 0 to 9. The smallest domino, #0, is 3.00 inches tall and will be toppled by a person to start the chain reaction. Each subsequent domino is 15% taller than the one before. What is the height of domino #9?
Answers
Answer:
8.604 in.
Step-by-step explanation:
We can use the formula for compound interest to find the height of domino #9:
A = P(1 + r)^n
where A is the final amount, P is the initial amount, r is the growth rate, and n is the number of compounding periods. In this case, P is the height of domino #0, r is 15% or 0.15, and n is 9 (since we want to find the height of domino #9).
Substituting the given values:
A = 3.00 in * (1 + 0.15)^9
Simplifying:
A = 3.00 in * 2.86797199
A ≈ 8.604 in
Therefore, the height of domino #9 is approximately 8.604 inches.
