Answer:
The length of the third side of the triangle is 30.
Step-by-step explanation:
Here is the formula for the Pythagorean Theorem:
[tex]a^{2} + b^{2} = c^{2}[/tex]
The hypotenuse, based on the problem, is 50. Anyways, let's get back to calculating!
We need to multiply 40 times 40 and 50 times 50.
40 times 40, or 40 squared, equals to 1600.
50 times 50, or 50 squared, equals to 2500.
[tex]c^{2} - b^{2} = a^{2}[/tex]
Now, let's subtract. 2500 - 1600 = 900. We need to find the square root of 900--which is 30, because 30 times 30, or 30 squared, equals to 900.
Answer:
30
Step-by-step explanation:
c=√a^2+b^2
a=√c^2-b^2 = √50^2-40^2 = 30

whatis the value of y?
Answers
The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.
Answer:
Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 - y2] / [x1 - x2]. If you know x, you can solve for y to find the y value for the slope of the line.

[tex]\left(x_1,\:y_1\right)=\left(-5,\:-1\right),\:\left(x_2,\:y_2\right)=\left(6,\:-2\right)[/tex]
[tex]=\left(\frac{6-5}{2},\:\frac{-2-1}{2}\right)[/tex]

Josiah is 5 years older than Alexis. In 7 years the sum of their ages will be 85. How old is Josiah now?
Can you help me solve it!!
Answers
Answer:
Step-by-step explanation:
Alexis is X years old
Josiah is X + 5 years old
in 7 years:
Alexis is x + 7 years old
Josiah is x + 5 + 7 => x + 12 years old
Sum of their ages is 85 :
x + 7 + x + 12 = 85
2x + 19 = 85
2x = 85 - 19 = 66
x = 66/2 = 33 => Alexis age
Josiah is x + 5 = 33 + 5 = 38 years old

Step-by-step explanation:
Step 1: Define Equation
-4(x + 2) = 4(2 - 2x)
Step 2: Solve for x
Divide -4 on both sides: -(x + 2) = 2 - 2xDistribute negative: -x - 2 = 2 - 2xAdd 2x on both sides: x - 2 = 2Add 2 on both sides: x = 4Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -4(4 + 2) = 4(2 - 2(4))Multiply: -4(4 + 2) = 4(2 - 8)Add/Subtract: -4(6) = 4(-6)Multiply: -24 = -24Here we see that -24 does equal -24.
∴ x = 4 is the solution to the equation.
Todd swam three trials of the 50-meter freestyle. His time was 32.15 seconds for the first trial, 31.67 seconds for the second trial, and 30.55 seconds for the third trial. Part A What is Todd's combined time for all three trials? Enter your answer in the box. seconds Part B How much faster was Todd's second trial than his first trial? Enter your answer in the box. second(s)
Answers
Answer:
A. 94.37 seconds
B. 0.48 seconds
Step-by-step explanation:
Total distance = 50 meters
First trial = 32.15 seconds
Second trial = 31.67 seconds
Third trial = 30.55 seconds
A. What is Todd's combined time for all three trials
Todd's combined time for the three trials = First trial + Second trial + Third trial
= 32.15 seconds + 31.67 seconds + 30.55 seconds
= 94.37 seconds
B. How much faster was Todd's second trial than his first trial?
Second trial = 31.67 seconds
First trial = 32.15 seconds
Time taken for first trial - Time taken for second trial -
= 32.15 seconds - 31.67 seconds
= 0.48 seconds
Todd's second trial was 0.48 seconds faster than his first trial

how many 7-digit numbers are there where all the digits are different and in increasing order? for example, the numbers 1345689 and 2456789 would be counted. (the first digit cannot be zero.) (a) 20 (b) 24 (c) 28 (d) 32 (e) 36
Answers
There are 544,320 7-digit numbers that are all unique and arranged in increasing order.
We apply the Fundamental Counting Principle to this issue. You are aware that a number has seven digits. According to this theory, you must multiply the potential integers for each digit. There are 9 potential numbers if the initial number can't be zero. Consequently, the first digit's value is 9. Any number, but less than 1, could be used for the second digit since it was already used in the first. Thus, 10 – 1 would equal 9. The value in the third digit must be less than 1 and in the second digit. In this case, 9 – 1 Equals 8. And the list goes on.
Therefore, the number of seven-digit numbers in which all digits are different and in increasing order is:
9 × 9 × 8 × 7 × 6 × 5 × 4 = 544,320
Hence, there are 544,320 7-digit numbers with all different digits in increasing order.
