For angle B which is 50 degrees,
hypotenuse = AB =?
Adjacent = BC = 2 units......(given)
cos 50 = adjacent / hypotenuse
0.643 = 2 / AB. .....(as cos 50 = 0.643 approx)
AB * 0.643 = 2
AB = 2 / 0.643
AB = 3.11 units(approx)

What fraction of all the 10-digit numbers with distinct digits have the property that the sum of every pair of neighboring digits is odd?
Answers
Answer:
1/126
Step-by-step explanation:
Answer attached, I hope this is the answer.
the sum of every pair of neighboring digits is odd must be odd number and even number in the neighbor. (different parity)
The fraction of all the 10-digit numbers with distinct digits that have the property that the sum of every pair of neighboring digits is odd is 1/126.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
For a 10-digit number to have the property that the sum of every pair of neighboring digits is odd, the digits must alternate between odd and even numbers.
Specifically, if the first digit is odd, then the second digit must be even, the third digit must be odd, the fourth digit must be even, and so on.
If the first digit is even, then the second digit must be odd, the third digit must be even, the fourth digit must be odd, and so on.
There are 5 odd digits and 5 even digits, so there are 5 choices for the first digit. After selecting the first digit, there are 5 choices for the second digit (it must be one of the other type), 4 choices for the third digit (it must be the opposite type of the second digit), 4 choices for the fourth digit (it must be the opposite type of the third digit), and so on.
Therefore, the number of 10-digit numbers with distinct digits that have the given property is:
5 x 5 x 4 x 4 x 3 x 3 x 2 x 2 x 1 x 1 = 5! x 4!
where the factorials arise from the number of choices for each digit.
The total number of 10-digit numbers with distinct digits is:
10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 10!
Therefore, the fraction of all the 10-digit numbers with distinct digits that have the given property is:
(5! x 4!) / 10! = (5! x 4!) / (10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) = 1/126
Thus,
The fraction of all the 10-digit numbers with distinct digits that have the property that the sum of every pair of neighboring digits is odd is 1/126.

A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:
Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).
A = x(x − 4) − 0.5(8)(x − 4) − 4(8)
A = x(x − 4) − (8)(x − 4) − 4(8)
A = x(x − 4) + (8)(x − 4) + 4(8)
A = x(x − 4) + 0.5(8)(x − 4) + 4(8)
Answers
Step-by-step explanation:
here .................
Answer:
A. A = x(x - 4) - 0.5(8)(x - 4) - 4(8)Step-by-step explanation:
Total area:
A(t) = x(x - 4)Area of the stage:
A(s) = 0.5(8)(x - 4)Area of the closet:
A(c) = 4(8)Area to be painted:
A = A(t) - A(s) - A(c)A = x(x - 4) - 0.5(8)(x - 4) - 4(8)Correct choice is A
Mrs. Pace opened an account with a deposit of $3,500 at the end of 5 years , the account was $4,690
Answers
Answer:
she earned a total of 1190 in 5 years. I don't know if this helps.
Step-by-step explanation:
The rate of interest with the given parameters is 6.8%.
Given that, Principal =$3,500, time period =5 years and the amount =$4,690.
We need to find the rate of interest.
What is the rate of interest?The interest rate formula helps in calculating the amount of money to be repaid towards a loan taken and the interest over the investment on fixed deposits, mutual funds, etc. The interest rate formula also helps in calculating the interest on credit cards. The interest rate for a given amount on simple interest can be calculated by the following formula,
Interest Rate = (Simple Interest × 100)/(Principal × Time)
Now, SI=Amount-Principal=4690-3500=1,190
rate of interest=(1,190×100)/(3,500×5)=6.8%
Therefore, the rate of interest with the given parameters is 6.8%.

When Georgia started Kindergarden, her parents set aside $10,000 in an account that yielded 5.6% interest compounded annually to pay for her college tuition. After 6 years of elementary school, 3 years of middle school and 4 years of high school, how much was in the account for Georgia’s college tuition?
Answers
Answer:
17,280
Step-by-step explanation:
first, you find 5.6 % of 10,000 which is 560. Then you have to figure out how many years the interest was coming in which is 13 years. you multiply the 560 by 13 years to get 7,280 and add that to 10,000. that's how you get your final answer of 17,280
