(a) A convex, 11-sided polygon can have at most how many obtuse interior angles? (b) A convex, 11-sided polygon can have at most how many acute interior angles?
Please provide an explanation!

Answers

A)  All 11 interior angles may be obtuse.
B)  At most 3 interior angles may be acute.

Explanation:
A)  To find the sum of the angles of a polygon, we use (n-2)(180), where n is the number of sides.  We would then have (11-2)(180)=9(180)=1620.  If the polygon is regular, we divide this by the number of sides; 1620/11 = 147.23.  Thus all 11 angles would be obtuse in a regular 11-sided figure.

B)  All interior angles of a polygon have an exterior angle that is supplementary to it.  If the interior angles are acute, that means the exterior angles are obtuse.  Likewise, if the interior angles are obtuse, the exterior angles would have to be acute.

The sum of the exterior angles of any polygon is 360.  This means there can be no more than 3 obtuse exterior angles; since obtuse means greater than 90, if there were 4 obtuse angles, 4 angles greater than 90, the sum would be more than 360.  If there can be no more than 3 obtuse exterior angles, then there can be no more than 3 acute interior angles.

What is the total amount of money Cheryl spent buying pins?


B.
How many pins did Cheryl add to her collection in March and April?


C.
What is the total cost of the pins that Cheryl bought in April?


D.
What is the difference between the number of pins bought in March and April?

Answers

A) She spent $264 in both March and April
B) She added 88 pins in total to her collection
C) She spent $168 in April
D) The difference is 24 pins
If you want me to explain the answers, just let me know :)
A. As with any purchase, the total cost is the cost of each item multiplied by the number of items.
  $3×(32 +56)
  = $3×88
  = $264

B. From part A, 88 pins.

C. $3×56 = $168

D. 56 -32 = 24
Cheryl bought 24 more pins in April than in March.

(Sometimes, "the difference of M and A" is intended to be strictly interpreted as "M - A". If that is the intent here, then the answer would be -24. More commonly, this wording is interpreted in common English to mean the value that results when the smaller number is subtracted from the larger one.)

A 2 liter drink costs $0.10 per deciliter. How much does the drink cost?

Answers

I liter is ten deciliters
0.1*20=2
2 dollars

The price of drink is given as 0.10 dollars per deciliter.

It says to find the cost of 2 liters of drink.

We need to convert the units from liters to deciliters.

We know 1 liter = 10 deciliters.

then 2 liters = 20 deciliters.

So we need to find the cost of 20 deciliters of drink at rate of 0.10 dollars per deciliter.

1 deciliter of drink cost = 0.10 dollars.

20 deciliter of drink would cost = 20 x 0.10 dollars = 2.00 dollars.

Hence, 2 liters of drink would cost 2 dollars.

Rebekah wants to read a certain number of pages each day during summer vacation. Today she reads 204 pages, which is 136% of her goal. How many pages does Rebekah want to read each day?

Answers

Rule of three
Pages        %
204     → 136%
x         → 100% (her goal)

x=204*100%/136%
x=150 pages

Answer: Rebeca wants to read 150 pages each day        
Given that Rebekah wants to read a certain number of pages each day and today she has read a total of 204 pages which is 136% of her goal, to find the number of pages that she wants to read per day we proceed as follows:
The percentage of pages she wants to read is 100%
thus the number of pages represented by this is:
100/136×204

A basketball player gets 2 free-throw shots when she is fouled by a player on the opposing team. She misses the first shot 40% of the time. When she misses the first shot, she misses the second shot 5% of the time. What is the probability of missing both free-throw shots?

Answers

The probability that the player misses the first shot =  40% = 0.4

When first shot is missed, the probability that she misses the second shot = 5% = 0.05

The probability of missing both shots will be the product of the probabilities of missing individual shots which will be:

Probability of missing both shots = 40% x 5% = 0.4 x 0.05 = 0.02 = 2%

Thus there is a 2% probability that the basketball player misses both free-throw shots.

Shryia read a 480 page long book cover to cover in a single session, at a constant rate. After reading for 1.5 hours, she had 402 pages left to read. Let P(t) denote the number of pages to read P as a function of time t (measured in hours). Write the function's formula.

Answers

The correct answer is P(t)=-52t+480.  Hope this helped.

Final answer:

The function representing the number of pages Shryia has left to read at a given time is P(t) = 480 - 52t, considering she reads at a constant rate of 52 pages per hour.

Explanation:

Shryia read a 480-page book in one session at a constant rate. Since P(t) represents the number of pages she has left to read at time t, after 1.5 hours, she had 402 pages left. To find the rate at which she reads, we can see that in 1.5 hours, she read 480 - 402 = 78 pages. Thus, her reading rate is 78 pages per 1.5 hours, or 52 pages per hour.

At time t=0, the book is completely unread, meaning P(0) = 480 pages. Her reading rate is constant, so the function is linear: for every hour that passes, 52 more pages are read. Therefore, the number of pages left, P(t), decreases by 52 for each hour. The function P(t) can then be defined as:

P(t) = 480 - 52t

Shondra found large candles on sale at her favorite store. She has a large family and many friends, so she bought as many of the candles she could fit in her trunk to give as gifts. Her trunk is 2 feet deep, 4 feet wide, and 3 feet long. If each candle comes in a cube box with 1 foot edges, how many candles will fit in her trunk?

Answers

The trunk of the car is shaped like a rectangular prism whose volume is length * width * height.

The volume of the trunk is LWH = 3 ft * 4 ft * 2 ft = 24 ft^3

The volume of a cube is the cube of the side (edge)
.
Each cubic box has volume V = s^3 = (1 ft)^3 = 1 ft^3

Now we divide the volume of the trunk by the volume of each cube box.

[tex] \dfrac{24 ft^3}{1 ft^3} = 24 [/tex]

Answer: She can fit 24 boxes in her trunk.

Yolanda closed on a 20 year home loan for $83,000. she chooses to buy only 1 point at closing. by buying a point at her closing, yolanda reduced her monthly payment by $7.63. based on the fact that yolanda chose to buy a point at closing, what would you infer is the minimum amount of time that she will own the home? A) 6 Years B) 11 Years C) 16 Years D) 20 Years

Answers

The correct answer is B) 11 years

Minimum amount of time that Yolanda will own the home is for at least 11 years

What is Division?

A division is a process of splitting a specific amount into equal parts.

To calculate the minimum amount of time that Yolanda will own the home

We need to determine how long it will take for the monthly savings to equal the cost of the point.

One point is equal to 1% of the loan amount, so Yolanda paid $830 (1% of $83,000) at closing for the point.

To find out how many months it will take for the monthly savings to equal the cost of the point, we divide the cost of the point by the monthly savings:

$830 ÷ $7.63 = 108.77 months

Since there are 12 months in a year, 108.77 months is 11 years.

Therefore, we can infer that Yolanda will own the home for at least 11 years

At a movie, 1/4 of the people in the theater were men, 5/8 were woman l, and the rest were children. If there were 100 more woman than children, what was the total number of people in the theater.

Answers

Let
x---------------> number of men in  the theater
y---------------> number of women in  the theater
z---------------> number of children in the theater
T--------------> total number of persons in the theater

we know that
T=x+y+z
x=(1/4)*T
y=(5/8)*T----------> equation 1
z=T-[(1/4)*T+(5/8)*T]-----> z=T-(7/8)*T------> z=(8*T-7*T)/8------> z=(1/8)*T
z=(1/8)*T----------> equation 2

y=100+z--------> equation 3
I substitute (1) and (2) in (3)
(5/8)*T=100+(1/8)*T------> (5/8)*T-(1/8)*T=100--------> T=200 persons

the total number of people in the theater was 200 persons
number of men in  the theater------> 200*(1/4)=50 men
number of women in  the theater----> 200*(5/8)=125 women
number of children in the theater----> 200*(1/8)=25 children

Suppose a shipment of 140 electronic components contains 3 defective components. to determine whether the shipment should be​ accepted, a​ quality-control engineer randomly selects 3 of the components and tests them. if 1 or more of the components is​ defective, the shipment is rejected. what is the probability that the shipment is​ rejected?

Answers

Final answer:

To find the probability that a shipment of 140 electronic components, with 3 defects, is rejected upon testing 3 components, calculate the complement (all non-defective) and subtract from 1.

Explanation:

The question involves determining the probability that a shipment containing 140 electronic components, with 3 being defective, is rejected based on a quality-control test of 3 components. To solve, consider the complementary probability - the chance all selected components are non-defective. First, calculate the probability of picking 3 non-defective components: (137/140) * (136/139) * (135/138). Then, subtract this probability from 1 to find the probability of the shipment being rejected.

1 - [(137/140) * (136/139) * (135/138)] equals the probability the shipment is rejected. After performing the calculations, you find that the shipment's rejection probability is determined by the presence of at least one defective component in the tested sample.

Q.8 What is the tail length?

If I'm correct you should make a fraction first
5.4            3.6

Now find the missing number
5.4 to 3.6 would be a difference of ÷ 1.5 so you must do the same for 4.8
     
           ÷1.5   
5.4               3.6
-----       to    -----
4.8                3.2
           ÷1.5

The tail length should be 3.2 feet

The tail length of an alligator with a body length of 3.6 feet is approximately 3.2 feet.

The problem states that the alligator's tail length, [tex]\(T\)[/tex], varies directly with its body length, [tex]\(B\)[/tex]. When two quantities vary directly, we can express this relationship using a proportionality constant, often denoted as [tex]\(k\)[/tex]. In this case, we have:

[tex]\(\frac{T_1}{B_1} = \frac{T_2}{B_2}\),[/tex]

where [tex]\(T_1\) and \(B_1\)[/tex] are the initial tail length and body length, and [tex]\(T_2\) and \(B_2\)[/tex] are the final tail length and body length.

Given that an alligator with a body length of 5.4 feet has a tail length of 4.8 feet, we can use this information to find [tex]\(k\):[/tex]

[tex]\(\frac{4.8}{5.4} = \frac{T_2}{3.6}\).[/tex]

Now, solve for [tex]\(T_2\):[/tex]

[tex]\(T_2 = \frac{4.8}{5.4} \times 3.6\).[/tex]

[tex]\(T_2 \approx 3.2\) feet.[/tex]

So, the tail length of an alligator with a body length of 3.6 feet is approximately 3.2 feet.

The tail length is 3.2 feet. This result confirms the direct variation between tail length and body length, where [tex]\(T\)[/tex] is proportional to [tex]\(B\)[/tex] with a proportionality constant of approximately 0.8889 (4.8/5.4).
