Adiya said that the first step to solving the quadratic equation x2 + 6 = 20x by completing the square was to divide 6 by 2, square that value, and add the result to both sides. Is Adiya’s solution method correct? Explain.

Answers

Answer 1

Answer:

Answer:

No, it is incorrect.

Step-by-step explanation:

The quadratic equation is

$x^2+6 = 20x$ or $x^2-20x+6=0$ . To complete square we take the coefficient of x divided by 2, square that value and add the result to both sides. In the equation given the number to do the process is 20, not 6, then the solution method is incorect.

Answer 2

Answer:

Answer:

NO it is not correct

Step-by-step explanation:

Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.

Classify the following triangle. Check all that apply.

Triangle is both acute and scalene.

What is Triangle?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

here, we have,

we know that,

A scalene triangle has three unequal sides and angles, whereas an acute triangle has three acute angles (measured fewer than 90 degrees). Consequently, the characteristics of an acute scalene triangle are as follows: three lines that cross each other. a trio of sharp angles All sides are not equal.

Given

All angles are less than 90 degrees so it is acute. The sides are of difference lengths so it is scalene.

On a particular day, the wind added 2 miles per hour to Jaime's rate when she was rowing with the wind and subtracted 2 miles per hour from her rate on her return trip. Jaime found that in the same amount of time she could row 44 miles with the wind, she could go only 36 miles against the wind.What is her normal rowing speed with no wind?

Answers

Answer:20

Step-by-step explanation:

Given Wind speed is 2 mile/hr

Let jamie speed be x km/hr

Also she covered 44 miles with wind in time t

$44=\left ( x+2\right )t$

Against the wind

$36=\left ( x-2\right )t$

divide the two equations

$(44)/(36)=(x+2)/(x-2)$

11x-22=9x+18

x=20 miles/hr

It is 40 because it gives you the even rate inbetween each of them

A scientist has two solutions, which she has labeled Solution A 60% and Solution B 75% Each contains salt. She knows that Solution A is salt and Solution B is salt. She wants to obtain ounces of a mixture that is salt. How many ounces of each solution should she use

Answers

Answer:

The answer is "180".

Step-by-step explanation:

Please find the complete question in the attached file.

Let's

x = ounces solution of A

y = ounces solution of B

$x + y = 180 \n\ny = 180 - x\n\n0.60x + 0.85y = 0.75(180)\n\n0.60x + 0.85y = 135\n\n$

Multiply both sides of the equation by 100 to remove the decimal points.

$60x + 85y = 13500\n\n60x + 85(180 - x) = 13500\n\n60x + 15300 - 85x = 13500\n\n-25x = -1800\n\nx = 72\ \ ounces\n\ny = 180 - 72 \n\ny = 108 \ \ ounces\n\n$

Answer:

greatest number of children that will receive a set of items on opening = 60

Step-by-step explanation:

We are told that local minor League baseball team has 120 ball caps 180 miniature baseball keychains and 240 glow-in-the-dark bracelets to give away to the children on opening day.

We are also told the items will be split into identical sets with no items left over.

Now, we want to find the greatest number of children that will receive a set of items on opening.

This implies that we have to find TH highest common factor of 120, 180 and 240

To do this, we will list out all the factors of each of the 3 numbers and then select the highest one that is common to the 3 of them.

Factors of 12 = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120

Factors of 180 = 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180

Factors of 240 = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240.

From all the factors listed above, the one that is the highest and appears in all three is 60

Thus, greatest number of children that will receive a set of items on opening = 60
