For the triangle shown, describe which sides are the legs and which are the hypotenuse. Explain how you know.
Answers
Answer:
legs: a and b
hypotenuse: c
Step-by-step explanation:
The legs of a right triangle are the two sides that intersect to determine the right angle. The remaining side is called the hypotenuse.
Answer:
a and b are the legs, and c is the hypotenuse
Step-by-step explanation:
The legs of a right triangle are always the sides that form the right angle. Looking at the picture, we see that at one corner of the triangle, there's a little square. Remember that this little square always denotes an angle with degree 90, which means this is the right angle. Then, since sides a and b form this angle, we know that a and b are the legs.
Another thing to remember is that the hypotenuse of a right triangle is the side that lies opposite to the right angle. Here, you can see that side c lies opposite to the right angle, so we know it's the hypotenuse.
Hope this helps!

In Scott’s backyard, he has a windmill that makes 5 ¾ of a turn every hour. How many turns does it make for 1 ½ hours?
Answers
Answer: 8 5/8 turns
Step-by-step explanation:
Hi, to answer this question we have to simply to multiply the number of turns that the windmill makes per hour (5 3/4) by the time asked (1 ½ hours).
Mathematically speaking:
5 3/4 x 1 1/2 = (5x4+3)/4 x (1x2+1)/2 = 23/4 x 3/2= 69/8 or 8 5/8 (mixed form)
In conclusion, the windmill makes 8 5/8 turns in 1 1/2 hours.

Step-by-step explanation:
ADC is a right angled triangle. So is ADB.
For right angled triangle ADC,
[tex] {ad}^{2} + {dc}^{2} = {ac}^{2} \\ {x}^{2} + {3}^{2} = {4}^{2} \\ {x}^{2} + 9 = 16 \\ {x}^{2} = 16 - 9 = 7 \\ x = \sqrt{7} [/tex]
For right angled triangle ADB,
[tex] {ad}^{2} + {db}^{2} = {ab}^{2} \\ 7 + {y}^{2} = {3.2}^{2} \\ 7 + {y}^{2} = 10.24 \\ {y}^{2} = 10.24 - 7 \\ {y}^{2} = 3.24 \\ y = \sqrt{3.24} \\ y = 1.8[/tex]
z=-302+19.3i?????????
Answers
Answer:
I don;t know what the question is but I know that z is an imaginary number.
Step-by-step explanation:
z=-302+19.3i
that means that it doesn't represent an actual number but is imaginary.
An imaginary number is a complex number that can be written as a real number multiplied by the imaginary unit i, which is defined by its property i2 = −1. The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25.
Student council at school would like to hold an end of the school year event for the eighth grade students they would like to know what’s students enjoy doing but do not have time to poll everybody Provide a suggestion for them to implement that would be unbiased
Answers
One unbiased suggestion is to create an online survey with a variety of activity options and allow students to anonymously vote for their preferences.
To ensure an unbiased approach in determining the activities for the end-of-the-school-year event, the student council can implement an online survey. This method allows all eighth-grade students to participate anonymously, eliminating potential biases based on social dynamics or peer pressure.
The survey should include a range of activity options, including both indoor and outdoor activities, sports, games, arts and crafts, and any other activities that may appeal to a diverse group of students. Additionally, students should have the option to suggest their own activity ideas to ensure that all interests are represented.
To further promote fairness, the survey should be distributed widely to all eighth-grade students through school email, online platforms, or even paper flyers if necessary. The survey should clearly state the purpose of gathering feedback and reassure students that their responses will be kept confidential.
After collecting responses, the student council can analyze the data to identify the most popular activity choices among students. This data-driven approach ensures that the end-of-the-school-year event reflects the interests and preferences of the majority of eighth-grade students, promoting inclusivity and fairness.
Overall, implementing an online survey provides an unbiased and transparent method for gathering feedback and making decisions about the event, ultimately enhancing the experience for all students involved.

Old man Jenkins left 1/2 of his money to his grandkids and 1/2 of that amount to his kids. He left 1/6 to his wife and the remaining $1000 to his tiger. How much did he leave altogether?
Answers
Answer:
12000
Step-by-step explanation:
Jenkins had x dollars
He left 1/2 of that to his grandkids
He has x-1/2x = 1/x
He leaves 1/2 of that to his kids
1/2*1/2 x = 1/4x to his kids
His wife gets 1/6x
The rest is 1000
The total is
grand kids + kids + wife + 1000
1/2 x + 1/4x + 1/6x + 1000
He started with x
1/2 x + 1/4x + 1/6x + 1000 =x
Multiply each side by 12 to get rid of the fractions
12(1/2 x + 1/4x + 1/6x + 1000) =x*12
6x+3x +2x +12000= 12x
Combine like terms
11x +12000 = 12x
Subtract 11x from each side
11x-11x +12000 = 12x-11x
12000=x
Since he started with x, he left 12000 dollars
Answer:
$12,000
Step-by-step explanation:
Let total be X
X - ½X = remaining after giving to grand kids
½(X/2) = ¼X remaining after giving to children
¼X - ⅙X = (3X - 2X)/12 = X/12 after giving to wife
X/12 = 1000
X = 12,000

Find the solution to the system of equations.y=-7x+3 y=-x-3
Answers
Answer:
x = 1; y = -4
Step-by-step explanation:
y = -7x + 3
y = -x - 3
since y = y then -7x + 3 = -x - 3
-7x + 3 = -x - 3
- 7x + 6 = -x (Because we add 3 to both sides)
x = 7x - 6 (Multiply both sides by -1)
-6x = -6 (Subtract 7x from each side)

The expression is given below.
⇒ 42 x 51
Simplify the expression, then we have
⇒ 42 x 51
⇒ (40 + 2) x (50 + 1)
⇒ 40 x 50 + 40 x 1 + 50 x 2 + 2 x 1

The sum of a number and seven is the same as double the number increased by three.
Answers
Answer:
Not true
Step-by-step explanation:
n+7 = 2n+3
Final answer:
The student's algebra problem is solved by setting up the equation x + 7 = 2x + 3, where x is the unknown number, and using algebraic manipulations to find that x equals four.
Explanation:
The student's question pertains to an algebraic expression where a number and seven have a sum that's equivalent to double the number increased by three. To express this situation mathematically, we could set up the equation x + 7 = 2x + 3, where x represents the unknown number. To solve for x, we start by subtracting x from both sides of the equation, leading to 7 = x + 3. Then, we subtract 3 from both sides to isolate x on one side, resulting in 4 = x. Therefore, the number we are looking for is four.
The properties of numbers, such as the commutative property of addition which states that A + B = B + A, apply to this equation. This principle indicates that the order in which you add numbers does not affect the sum, a foundational concept taught across various arithmetic and algebra contexts in mathematics.

Find the missing length of the triangle (I need a step by step answer please)
Answers
Answer:
c = 12.5
Step-by-step explanation:
This is a right triangle so we can use the Pythagorean theorem (a^2 + b^2 = c^2)
lets say 10 = a and 7.5 = b (this is because they are the legs of the triangle and variables a and b represent the legs of the triangle)
plug into the Pythagorean theorem.
10^2 + 7.5^2 = c^2
simplify (here you just square 10 and 7.5)
100 + 56.25 = c^2
simplify
156.25 = c^2
simplify
(here you get the square root of 156.25 and c^2, the positive square root of 156.25 is 12.5 and the square root of c^2 is c)
12.5 = c
Answer: 12.5
Step-by-step explanation: the pythagorean theorem is used to solve this equation theorem is (a x a) + (b x b) = (c x c) this is also called squaring
first substitute them in : (10 x 10) + (7.5 x 7.5) = (c x c)
then multiply 10 x 10 = 100 and 7.5 x 7.5 = 56.25 then substitute again
100 + 56.25 = (c x c) then add
156.25 = (c x c) then calculate the square root of 156.25 which is 12.5
