Answers

Answer 1
The hypotenuse is 20.59. 10^2+18^2=C^2
Answer 2

The hypotenuse of the paper is 2√106 cm.

What is Pythagorean theorem ?

Hypotenuse ² = Height ² + Width ²

Know more about Pythagorean theorem,

The Pythagorean Theorem, also known as the Pythagoras Theorem, explains the relationship between the three sides of a right triangle. According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a right triangle. Pythagorean triangles are the name given to the sides of a right triangle. Let's learn about Pythagorean theorem, formula, derivation and examples in detail.

The history of the Pythagorean theorem goes back to the ancient Babylonian and Egyptian era. The Greek mathematician Pythagoras of Samos introduced the Pythagorean theorem. Pythagoras was born in 570 BC. The Greek philosopher studied with other monks and formed a group of people; he finally stated the Pythagorean theorem. Even before Pythagoras, the ratio was shown on a Babylonian tablet 4000 years ago, but the theorem is published under the name of Pythagoras.

Here given, a triangle shaped paper’s height is 18 cm and width is 10 cm.

We want find the hypotenuse of the paper ?

Here, height of the paper = 18 cm and width of the triangle = 10 cm.

[tex] = {18}^{2} + {10}^{2} \\ = 324 + 100 \\ = 424[/tex]

So,

[tex]hypotenuse = \sqrt{424} \\ = \sqrt{2 \times 2 \times 2 \times 53} \\ = 2 \sqrt{2 \times 53} \\ = 2 \sqrt{106} \: cm[/tex]

Therefore,the hypotenuse of the paper is 2√106 cm.

Liliana used 4 dark power crystals to raise 14 zombie soldiers. She wants to know how many zombie soldiers (z) she can raise with 10 dark power crystals. How many zombie soldiers can Liliana raise with 10 power crystals?

Answers

4c = 14z.
1c = 3.5z.
10c = 35z.
So she can raise 35 with 10 power crystals. Hope it helps !:)

Answer:- Liliana can raise 35 zombie soldiers with 10 power crystals.


Explanation:-

Let the number of zombie soldiers raised by 10 dark power crystals be 'x'.

Zombie raised by 4 power crystals = 14

Since the number of zombie and power crystals are in direct proportion.

Therefore, we get

[tex]\frac{x}{10}=\frac{14}{4}[/tex]

Multiply 10 on both the sides, we get

[tex]\Rightarrow\ x=\frac{14}{4}\times10=35[/tex]

Liliana can raise 35 zombie soldiers with 10 power crystals.

Re-arranging the inequality to find the test points:

This means, we need to test the inequality for x = -10, x = 0 and x = 7

Since question assumes that x > 0, so we ignore the values less than 0.
So the test points are x = 0 and x = 7

At x = 0 the expression is undefined.
Between x = 0 and x = 7 the value of expression [tex] \frac{(x-7)(x+10)}{x}[/tex] is negative. At x = 7 the value of expression is 0. Above x = 7 the value of expression is positive.

[tex] \frac{x}{4} = \frac{6}{12} [/tex] solve the proportions

Answers

To solve a problem like this, you can use a method called cross-multiplying. This is when you multiply the denominator of the first fraction by the numerator of the other and then multiply the two remaining numbers.

[tex] \frac{x}{4} = \frac{6}{12} [/tex]  To make this easier on yourself, simplify first!
[tex] \frac{x}{4} = \frac{1}{2} [/tex]   Multiply x by 2 and multiply 4 by 1.
2x = 4   Divide both sides by 2.
x = 2

You can check this by comparing the fractions with 2 in the place of x.

[tex] \frac{2}{4} = \frac{6}{12} [/tex]   Simplify!
[tex] \frac{1}{2} = \frac{1}{2} [/tex]

a motorboat travels 432 kilometers on 6 hours going upstream and 384 km in 4 hours going downstream. What is the rate of the boat in still water and what is the rate of the current.
please help slove and steps

Answers

Going upstream: 432 km / 6 hours = 72 km/h
Going downstream: 384 km / 4 hours = 96 km/h
Going upstream against the current means that the effective speed is:
r_boat - r_current = 72
Meanwhile, going downstream with the current means;
r_boat + r_current = 96
Adding both equations (to cancel out r_current) gives:
2r_boat = 72 + 96
r_boat = 84 km/h
Substituting back into one of the original equations: r_current = 12 km/h.

round 543,873 to nearest ten thousand

Answers

For this case we have the following number.
 543,873

 1) Remember that when rounding the number to the nearest tousand, the number must have the first three digits (from right to left) equal to zero.

 2) The fourth digit of the number (from right to left) must be rounded to the next number only if the third digit (from right to left) is greater than or equal to 5.

 3) Following steps 1) and 2) we have the number rounded to the nearest tousand is:544,000

 Answer:
 Round to the nearest tousand:
 544,000

Final answer:

To round 543,873 to the nearest ten thousand, we assess the digit in the ten thousand's place (4) and the digit to its right (3). Since the latter is less than 5, we round down, resulting in 540,000.

Explanation:

The question asks to round the number 543,873 to the nearest ten thousand. To do this, we look at the digit in the ten thousand's place, which is 4, and then look at the digit to its right, which is 3. If the digit to the right is 5 or above, we would round up. However, since it's less than 5, we round down. Therefore, 543,873 rounded to the nearest ten thousand is 540,000.

Samples of size n = 9 are selected from a population with μ = 80 with σ = 18. what is the expected value of m, the mean of the distribution of sample means?​

Answers

Answer: 
80

Explanation:
The mean of the distribution of sample means always target the population mean. What this line tells is that whatever the population mean will be, the mean of the distribution of sample means will be same. Since the population mean is 80, the mean of distribution of sample means will also be 80.

However, the standard deviation of the sample distributions is different and is equal to the population standard deviation divided by square root of sample size. So in this case the standard deviation of distribution of sample means will be 6 .

This is a conditional probability. 
Denote the events like this:
F: Getting a favorable response .
First compute the number of participants: 62+38= 100.
The number of Male with favorable opinion: 40. 
We deduce the probability:
[tex]P(F\vert M)=\dfrac{40}{100}=\dfrac{2}{5}[/tex]

The probability that a male and has a favorable opinion is selected is 2/5

Further explanation

The probability of an event is defined as the possibility of an event occurring against sample space.

Combination ( Selection )

Combination is the number of ways to select objects.

[tex]\large {\boxed {^nC_r = \frac{n!}{r! (n - r)!} } }[/tex]

Let us tackle the problem.

This problem is about Probability.

Given:

Of the 62 favorable responses, there were 40 males and 22 females.

Of the 38 unfavorable responses, there were 15 males and 23 females.

There were total (40+15) males = 55 males

Let P(M) = probability a male is selected

[tex]P(M) = \frac{\texttt{Number of Male Citizens}}{\texttt{Total Number of Citizens}}[/tex]

[tex]P(M) = \boxed{\frac{55}{100}}[/tex]

There were 62 favorable responses

Let P(F) = probability citizens has a favorable opinion is selected

[tex]P(F) = \frac{\texttt{Number of Favorable Opinion Citizens}}{\texttt{Total Number of Citizens}}[/tex]

[tex]P(F) = \boxed{\frac{62}{100}}[/tex]

Let P(M ∪ F) = probability a male or citizens has a favorable opinion is selected

[tex]P(M \cup F) = \frac{\texttt{Number of Favorable Opinion Citizens or Male Citizens}}{\texttt{Total Number of Citizens}}[/tex]

[tex]P(M \cup F) = \frac{40 + 15 + 22}{100}[/tex]

[tex]P(M \cup F) = \boxed{\frac{77}{100}}[/tex]

At last , the probability a male and has a favorable opinion could be calculated as follows:

[tex]P(M \cap F) = P(M) + P(F) - P(M \cup F)[/tex]

[tex]P(M \cap F) = \frac{55}{100} + \frac{62}{100} - \frac{77}{100}[/tex]

[tex]P(M \cap F) = \frac{40}{100}[/tex]

[tex]P(M \cap F) = \large{\boxed {\frac{2}{5}} }[/tex]

Imagine a world in which only decimal,not fractions,are used.how would your life be different

Answers

This answer depends a bit on your age, the types of activities you partake in and the kind of work you do/are planning to do but here goes:

I am thinking of some uses of fractions where decimals are not typically used. One might be cooking. Often the ingredients (1/2 cup of four and so on) are measured using fractions. If you were in a world with decimals you might need to make (1/3) the servings of a recipe that calls for 1/4 of a cup of some ingredient and instead of 1/12 have to deal with a long repeating decimal that probably would need to be approximated so would not be precise.

While on the subject of food ordering pizza (1/2 with pepperoni, 1/4 mushrooms and 1/4 plain) would be doable after you got used to it but probably not as comfortable. Dividing up slices of pizza among friends (one slice is usually 1/8 of a pie) might be awkward though eventually doable.

Estimation - the biggest issue is exactitude versus estimation. When we use a fraction like 1/3 that is an exact value, but when we use .333 or .3333333 no matter how many 3s we use we are only estimating because the 3s go on forever and we can't write them forever. Yes, we can use .3 (with a bar over the 3, but now try to multiply that with .456565656 with a bar over the 56. This becomes practically impossible unless we estimate ... so the biggest issue would be that you would lose precision in many calculations and measurements and have to deal with answers that are good enough (but not exact).

Now say you work on some major car company or you design bridges or you are a scientist developing medicine that cures diseases, would not you want the ability to measure and compute precisely? If I split the pizza up wrong it is not a big deal. If I use a little more flour or a little less than I should in the recipe it might not make much of a difference in the end but if I am doing something that impacts the health, safety or well being of another human being, I would not want to live in a world where I have to estimate and can't count on having the exact, precise value.

The answer is option D. (15°)

Two angles are said to be supplementary when both angles together make a straight line. Since the measure of a straight line is 180°, it then follows that the sum of two supplementary angle is 180°

Let the unknown angle = x
x is supplementary to 165°
⇒ x + 165° = 180°
x = 180° - 165°
x = 15°
The answer to this is d. 15. 

Supplementary angles are two angles that equal to 180. So you take the known angle (165) and subtract it from 180 to find the other angle measure.

180-165=15
