Solve for x and y please !!

Answers

isosceles triangle
y = 72 yd

x^2 = 72^2 + 72^2
x^2 = 2(72^2)
x = 72√2 yd

since both inside angles are 45, the height and the base would be the same

 the height is 72 yd

 so the base (y) would also be 72 yd

Y = 72


 and x would equal y * sqrt(2)

Which statements prove that a quadrilateral is a parallelogram?

Select each correct answer.

Quadrilateral DEFG has one diagonal that bisects the other diagonal.

Quadrilateral DEFG has only one set of opposite angles that are congruent.

Quadrilateral DEFG has two sets of consecutive angles that are supplementary.

Quadrilateral DEFG has one set of opposite sides that are both congruent and parallel.

Answers

First, let's list the properties of parallelograms. *Opposite sides are congruent
*Opposite angles are congruent
*Consecutive angles are supplementary
*The diagonals of a parallelogram bisect each other.

Statement 1: This statement does not prove that the quadrilateral is a parallelogram because both diagonals have to bisect each other and not only one.

Statement 2: A parallelogram has two sets of opposite angles not only one. The statement would prove the quadrilateral is a parallelogram if it said that the quadrilateral has two sets of opposite angles that are congruent.

Statement 3: This statement is a property of a parallelogram. However, it doesn't prove that a quadrilateral is a parallelogram.

Statement 4: This statement proves that the quadrilateral is a parallelogram. If the statement, however, said that the quadrilateral has one set of opposite sides that are only congruent or only parallel, then it would not prove the quadrilateral to be a parallelogram.

The statement "Quadrilateral DEFG has one set of opposite sides that are both congruent and parallel" proves that a quadrilateral is a parallelogram.

A quadrilateral has 4 sides and the sum of interior angles are [tex]360^\circ[/tex] where as the parallelogram is a quadrilateral whose oppposite sides are parallel to each other.

The following statements are:

A). The statement "Quadrilateral DEFG has one diagonal that bisects the other diagonal" is incorrect because both diagonals have to bisect each other.

B). The statement "Quadrilateral DEFG has only one set of opposite angles that are congruent" is incorrect because a quadrilateral is a parallelogram when it has two sets of opposite angles that are congruent.

C). The statement "Quadrilateral DEFG has two sets of consecutive angles that are supplementary" is incorrect although it is a property of parallelogram.

D). The statement "Quadrilateral DEFG has one set of opposite sides that are both congruent and parallel" is correct this statement proves that a quadrilateral is a parallelogram.

The perimeter of a given is an integer. the length of side one is 4 times the length of side 2. side three is 33. what is the largest and smallest possible perimeter

Answers

I assume this is a triangle.
the sum of two sides of a triangle has to be larger than the third side, and the difference has to be smaller than the third side
the two unknown sides are x and 4x
x+4x>33  => x>6.6
4x-x<33 =>   x<11
6.6<x<11
because the perimeter is an integer, the smallest x is 7 and the largest is 10
therefore the largest perimeter is 10+40+33=83
the smallest perimeter is 7+28+33=68

a. Chuy has a good plan and will have exactly $1,350 saved at the end of 27 weeks.

b. Chuy must increase the amount he saves each week in order to meet his goal at the end of 27 weeks.

c. Chuy will save more than he needs and will meet his goal in less than 27 weeks.

d. There is not enough information given to make a conclusion about Chuy's plan.

Answers

i would say that the answer is c because with the math done in 27 weeks you wouldve earned 1,485

Answer:

Option C. is correct.

Step-by-step explanation:

Chuy needs $1,350 to buy a  new television.

he decides to save the same amount of money each week for 27 weeks.

In 8 weeks Chuy saved  = $440

In 1 week  Chuy saved $440 ÷ 8 = $43.00

Therfore, in 27 weeks Chuy can save = 43.00 × 27 = $1485.00

Chuy can save $1485.00 in 27 weeks that is more than he needs.

So Option c. would be correct Chuy will save more than he needs and will meet his goal in less than 27 weeks.

A quiz consists of 20 multiple-choice questions, each with 5 possible answers. for someone who makes random guesses for all of the answers, find the probability of passing if the minimum passing grade is 60 %.

Answers

Final answer:

To find the probability of passing the quiz, we need to determine the minimum number of correct answers needed to achieve a passing grade. The probability of guessing the correct answer for each question is 1/5, so the probability of getting exactly 12 correct answers is calculated using the binomial probability formula.

Explanation:

To find the probability of passing the quiz, we need to determine the minimum number of correct answers needed to achieve a passing grade. Since a passing grade is 60%, this corresponds to 12 correct answers out of 20. The probability of guessing the correct answer for each question is 1/5, so the probability of getting exactly 12 correct answers is given by the binomial probability formula:

P(X = k) = (nCk) * p^k * (1-p)^(n-k)

Using this formula, we can calculate the probability of passing the quiz.

#SPJ12

Final answer:

The problem can be solved using binomial distribution principles where the number of trials is the total number of questions (20), success is answering a question correctly, and the probability of success is 1/5 since the answers are guessed randomly. Calculate the cumulative binomial probability for getting 12 (minimum passing grade at 60%) to 20 (total questions) correct answers. This gives the probability of passing the test.

Explanation:

The question asks about the probability of passing a 20 question quiz with each question having 5 possible answers, by making random guesses. To pass the quiz, a grade of 60% is required which means at least 12 questions need to be answered correctly. Since the answers are guessed randomly, the chance of picking the correct answer for each question is 1/5 or 0.2.

We can treat this problem as a binomial distribution problem, where the success is answering a question correctly. In this case, the number of trials is n=20 (the total number of questions), the number of success k is 12 or more (the minimum number of correct answers required to pass), and the probability of success p is 0.2 (since there are 5 multiple choice options per question).

Calculating the cumulative binomial probability for k=12 to n=20, we get the required probability of passing the test. Given that we have to calculate multiple probabilities and sum them, this problem might be easier to solve if you have statistical software or a calculator that can compute binomial distributions.

In the chemistry lab an experiment requires 500ml of one ingredient to be mixed with 1,000 ml of another. How many liters is the solution

Answers

Hello!

1000 + 500 = 1500

1500 ml = 1.5 litres.

So. 1.5 L is the solution.

I hope this helped you out! :)
Final answer:

After mixing 500 ml with 1,000 ml, the total volume of the solution is 1.5 liters.

Explanation:

To find out how many liters the solution is after mixing 500 ml with 1,000 ml, you simply add the volumes together and convert to liters. First, you have a total volume of 500 ml + 1,000 ml = 1,500 ml. Now, notice that you are going from a smaller unit (milliliters) to a larger unit (liters). Since there are 1,000 milliliters in a liter, you will need to divide by 1,000:

1,500 ml ÷ 1,000 = 1.5 liters.

Therefore, the solution will have a total volume of 1.5 liters.

Two numbers have a difference of 24. What is the sum of their squares if it is a minimum?

288

1156

366

576

Answers

Let "a" and "b" be some number where:

a - b = 24

We want to find where a^2 + b^2 is a minimum.  Instead of just logically figuring out that the answer is where a=b=12, I'll just use derivatives.

So we can first substitute for "a" where a = b+24

So we have (b+24)^2 + b^2 = b^2 +48b +576 + b^2
And that equals 2b^2 +48b +576

Then we take the derivative and set it equal to zero:

4b +48 = 0
4(b+12) = 0
b + 12 = 0
b = -12

Thus "a" must equal 12.

So:
a = 12
b = -12

And the sum of those two numbers squared is (12)^2 + (-12)^2 = 144 + 144 = 288.

The smallest sum is 288.

H(x)=-4x+3;when h(x)=11

Answers

To solve this, since you know that h(x) is 11 and that it also equals -4x+3, you set them equal to one another which would look like this: 11=-4x+3.
Then, to solve for x, which is what I am assuming the question is asking, you would subtract 3 from both sides to isolate -4x, which would result in this:
-4x=8
Now, to solve for x, divide both sides by -4, and you get your answer which is x=-2
