The lengths two sides of a triangle are 10 cm and 11cm. Between what two measures should the length of the third side fall?

Answers

Step-by-step explanation:

a triangle can only be a triangle (all sides connect with each other), if every side is less than the sum of the other 2 sides.

so, the third side must be shorter than 10+11 = 21 and longer than 11-10 = 1, so that the side of 11 cm is shorter than the sum of the other two sides.

Answer:

1 < x < 21

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides , that is

11 - 10 < x < 11 + 10

1 < x < 21

(5 + 13 + 21 + ......... + 18) = ?

Answers

Correction:

5+13+21+...+181

First term = 5

Common difference = 13-5 = 8

Last term = an = 181

⇛a+(n-1)d = 181

⇛5+(n-1)(8) = 181

⇛ 5+8n-8 = 181

⇛ 8n-3 = 181

⇛ 8n = 181+3

⇛ 8n = 184

⇛n = 184/8

⇛ n = 23

Sum of the first n terms = Sn = (n/2)(a+an)

Sum of 23 terms = S 23

⇛(23/2)(5+181)

⇛ (23/2)(186)

⇛23×93

Evaluate 3x2 - 2xy + 4y2 for x = -1 and y = -2. .

Answers

Answer:

The answer is 12

Step-by-step explanation:

3x² - 2xy + 4y²

Let x = -2

y = -1

3(-2)² - 2(-2)(-1) + 4(-1)²

= 3(4) - 2(2) + 4(1)

= 12 - 4 + 4

= 12

What is 12,925 to the nearest ten thousand

Answers

Answer:

To round to the nearest 10,000, you look at the number immediately to the right. If this number is 5 or above, you add 1 to the column in question and zero all numbers to the right. If the number immediately to the right is 4 or less, you just zero all numbers to the right.

In this case, the 10,000 column is the column with the 1. The number immediately to the right is 2. This is 4 or less, so we set all numbers to the right of the 10,000 column to zero.

A pianist charges $200 to perform at a restaurant. At the end of the night she collected her tips and left with a total earning of $310. Write an equation and solve for the amount she made in tips for the performance.

Answers

Answer:

310-200= T

Step-by-step explanation:

310 = 200 + x

Let’s break this down. 310 is their total earning, 200 is our set price for performing, and x represents how much she earned in tips.

310 = 200 + x

110 = x

At a bowling alley, the cost of shoe rental is $2.75 and the cost per game is $4.75. If f (n) represents the total cost of shoe rental and n games, what is the recursive equation for f (n)?

f (n) = 2.75 + 4.75 + f (n − 1), f (0) = 2.75
f (n) = 4.75 + f (n − 1), f (0) = 2.75
f (n) = 2.75 + 4.75n, n > 0
f (n) = (2.75 + 4.75)n, n > 0

Answers

The recursive equation for f(n) will be:

f(n) = 2.75 + 4.75n, n > 0

The cost of the shoe rental = $2.75

The cost of 1 game = $2.75

The cost if n games = 4.75n

The total cost of shoe rental and n games = Cost of the shoe rental + cost of n games

Let the total cost of shoe rental and n games be f(n)

f(n) = 2.75 + 4.75n

Since at least 1 game will be played,

the recursive equation for f(n) will be:

f(n) = 2.75 + 4.75n, n > 0

If y’all show y’all work and do all the questions I add extra extra points

Answers

Answer:

For 5.) I believe the slope is 3/5, for 6.) the slope is -2/8 (-1/4 when simplified) and the y-int is 2, for 7.) the slope is 6/2 (3/1 when simplified), for 8.) the slope is -2/4 (-1/2 when simplified) + the y-int is -3, and for 9.) the slope is 1/6.

Step-by-step explanation:

5.) the slope is 3/5 because it rises 3 and runs 5 (from the two plotted points)

6.) the slope is -2/8 (-1/4) because from the two points, it runs 8 and drops 2 (so -2) + when simplified its -1/4 because -2/8 divided by 2 on top and bottom would get you -1/4. And y-int is 2 because on the y-axis, the line is going through 2.

7.) the slope is 6/2 (3/1) because it rises 6 points and runs 2 (from the two points) and when simplified (6/2 divided by 2 on both top and bottom) would get you 3/1.

8.) the slope is -2/4 (or -1/2) because it runs 4 and drops 2 (which would be -2), and when simplified it gets you -1/2.

9.) the slope is 1/6 because between the two points, you rise one and run 6. Which gets you 1/6

A Tejano (Texas-born Mexican) living in San Antonio but not volunteering to defend the Alamo Anglo soldiers defending the Alamo Mexican General Santa Ann Kelly is writing a research report for social studies class about the Salem witch trials. She wants to revise the introductory paragraph to include a clearthesis statement. Read Kelly's draft introductory paragraph and answer the question that follows.The Salem witch trials took place in 1692. Several women in a Massachusetts village were accused of witchcraft by some children: The adults did not brush these claims off as kids' make-believe stories, though. The cases against these women were heard in a special court. By the time the trials came to an end, well over 100 people had been accused of witchcraft. To most people today, it seems unbelievable that the trials ever took place, but that time people really did believe in, and fear, witches. Life was difficult for the people of Salem Village, and there was also a lot of tension among neighbors.Which sentence would be the best thesis statement that Kelly should add to complete her introductory paragraph?A.The key to understanding the Salem witch trials lied in understanding the time period in which they took place, including such important factors as: 1) common religious beliefs and superstitions of the era; 2) hardships in life which caused people to seek solutions and scapegoats; and 3) the rigid and highly stratified society of colonial New England in which people may have tempted to take out personal grudges against more privileged neighbors in unusual ways.B.Today, it is still not clear whether there really were witches in Salem. We simply don't have the archeological or written evidence to say if it is true or not. However, some ghost-hunters, psychics, and mystics have explored the geographic area for "psychic vibes", and they report unusual supernatural forces.C.The Salem witch trials show why it is important to question what kids say. Children can come up with all sorts of random and fanciful ideas. Some children even believe they have invisible companions!D.Several centuries later, sad events like the Salem witch trials are still taking place all around the world: For example, in some partsof the world, such as the mountain villages of Switzerland or the highlands of Scotland, pagan celebrations take place around New Year's Eve in which a straw effigy of a person is ritually burned under a full moon A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3.
