X^2+17x+50=0 to the nearest tenth.

Answers

Answer 1

Since you cannot really factor this problem easily, we are going to resort to the quadratic formula!

x= -b+or- sqrt(b^2-4ac)    / 2a

x=-17+ or - sqrt(17^2-4*50)   /2

x=-17+ or - sqrt89 /2

Now we just need estimate sqrt 89 which is about 9.43 and I will not bother to show the step I did to estimate its about 9.43.

So x= -17+ or -9.43 /2

x= -26.43/2 or -7.57/2

x=-13.215 or -3.785

Round to nearest tenth digit.

x= -13.2 or -3.8

Hope this helps any questions just ask in the comments.

If the value of a quarter of a kilogram is ₹ 40, how much money will be the value of 100 grams?​

Answers

Answer:

₹16

Step-by-step explanation:

1/4 kg = ₹ 40

1kg = 40×4 = ₹160

1000g = 1kg

100g = 100/1000 kg

= 0.1kg

0.1kg= 0.1×160 = ₹16

First convert 40 grams to kg. A kilogram is 1000 grams, so you divide 40 by 1000 which is .04 kg.

40 grams * 1 kg / 1000 grams = .04 kg

(Note here that 1 kg = 1000 grams meaning that 1 kg / 1000 grams = 1; anything divided by itself is one; therefore, when I multiply by 1 kg / 1000 grams I’m not changing the value, only the units.)

Then you simply multiply the price per kg by the number of kg giving 6.6.

.04 kg * 165 / 1 kg = 6.6

Step-by-step explanation:

30% = 198 (People for the first hour it was open)

1% = 6.6 (1% for people at the park yesterday)

100% = 6.6 x 100 = 660 (Everybody at the park)

Answers

Answer:

Step-by-step explanation:

The kind of sample that is being described is known as a stratified sample. This would be the type of sample because the researchers are dividing the entire student population that exists into various different categories or groups. The groups that have been created are home-schooled students, private school students, and public school students. All of the students are still part of the student population and therefore represent their groups.

A store manager buys binoculars for $45 each. He marks up the cost by 40% to get the store price. Then the store has a sale and the store price is reduced by 10%. What is the sale price of the binoculars?​

Answers

Answer:

$56.70

Step-by-step explanation:

The cost plus markup is found by multiplying $45 by 1.40:  $63.

With the 10% price reduction, the sale price is 0.90($63) = $56.70.

Regarding 1.40:  the '1' results in the full price to the manager plus the '0.40' markup.

What kind of triangle is 15,16,21

Answers

Answer:

here is my answer is took me alot of time

Step-by-step explanation:

The calculator solves the triangle specified by three of its properties. Each triangle has six main characteristics: three sides a, b, c, and three angles (α, β, γ). The classic trigonometry problem is to specify three of these six characteristics and find the other three. Of course, our calculator solves triangles from any combinations of main and derived properties such as area, perimeter, heights, medians, etc. Usually by the length of three sides (SSS) or side-angle-side or angle-side-angle.

How does this triangle calculator solve a triangle?

The calculation of the general triangle has two phases:

expert phase - which is different for different tasks. From the entered data, the calculator tries to calculate the sizes of three sides of the triangle. He gradually applies the knowledge base to the entered data, which is represented in particular by the relationships between individual parameters of the triangle. These are successively applied and combined, and the parameters of the triangle calculate. Calculator iterate until the triangle has calculated all three sides.

For example, from the given area of the triangle and the corresponding side, the appropriate height is calculated. From the known height and angle, the adjacent side, etc., can be calculated. They use knowledge, e.g., formulas (relations) Pythagorean theorem, Sine theorem, Cosine theorem, Heron's formula, solving equations and systems of equations.

The second stage is the calculation of the properties of the triangle from the known lengths of its three sides.

Examples of how to enter a triangle:

All the sides of the triangle are different and do not satisfy Pythagoras' theorem. Then the triangle is a scalene triangle.

What is the triangle?

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

The dimensions of the triangle are 15, 16, and 21.

Check whether it satisfies the Pythagoras theorem or not. Then we have

H² = P² + B²

21² = 16² + 15²

441 = 256 + 225

441 ≠ 481

Every one of the sides of the triangle is unique and doesn't fulfill Pythagoras' hypothesis. Then the triangle is a scalene triangle.
