Graph (1,1), (1,2), (1,3), (1,4)

Answer:

There is not a way that I can show you how to graph it, so I will try and explain it.

Step-by-step explanation:

(1,1)

^  ^     y-axis

x-axis

You are just going right however many, and then up however many it says.

So if it's (1,1) you will go right one space, and then up one space.

Once you have all of your points on the graph, you put a line through them.

Yes, the are the right degrees.

Answer:

I do agree

Step-by-step explanation:

I know 10. is right because it is a right angle which id usually 90 degrees.

I'm pretty sure 11. is right because I know it is an obtuse angle and I think the number you gave is close if not it.

I know 12. is right because that angle looks the same as DBA which is already labeled 54 degrees.

I know 13.  is right because 180 degrees is always a straight line.

Answers

Answer:

(x - 8)² = 38

Step-by-step explanation:

Given

x² - 16x + 26 = 0 ( subtract 26 from both sides )

x² - 16x = - 26

Using the method of completing the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 8)x + 64 = - 26 + 64

(x - 8)² = 38 ← as required

TRUST ME I GOT EXCEPTED INTO HARVARD

Answer:

12/17 is greater

Step-by-step explanation:

12/17 is greater than 5/8 because to determine which fraction is greater you need to have the same denominator. To get the same denominator I multiplied 17 by 8 and 8 by 17. Since what you do the denominator you have to do the same to the numerator, you would multiply 12 by 8 and 5 by 17 which would lead you to get 12/17= 96/136 and 5/8= 85/136. So, 96/136 > 85/136.

Other than 1, what are the perfect square factors for 792? From least to greatest.

Answers

Answer:

4 and 36

Step-by-step explanation:

Perfect squares are 1, 4, 9, 16, 25, 36, 49, 64, 81

Dividing 792 by these perfect squares results the integer (only) quotients

                                 792 (792 divided by 1)

                                 198 (792 divided by 4

                                   22 (792 divided by 36

                                       

The perfect square factors of  792 are, in ascending order, 4 and 36.

From least to greatest, the perfect square factors of 792 are 4, 9 and 36.

Perfect squares are those that are acquired when an integer multiplies itself. For instance, 4 is a perfect square that is a result of 2 multiplying itself.

Other perfect factors include:

4 → 9 → 16 → 25 → 36 → 49 → 64 → 81 → 100 → 121 → 144 → 169 → 196 → 225 → 256 → 289 → 324 → 361

The factors of 792 are attached to this answer.

The perfect squares that are also factors of 792 are:

4 , 9 and 36

In conclusion, 792 has perfect factors of 4, 9 and 36

Tiffany ate 1/4 of a pizza. If there were 16 slices of pizza to begin with, how many slices did Tiffany eat?​

Answers

Answer:

Tiffany ate 4 slices of pizza

Step-by-step explanation:

1/4 of 16 is 4

Tiffany ate 4 slices of pizza.

What is fraction?

" Fraction is a representation of a part of whole object which is divided into equal parts."

According to the question,

Total number of pizza slices = 16

Part of pizza ate by Tiffany   = 1 / 4

Therefore,

Number of slices Tiffany ate = ( 1/ 4) of 16

                                                = (1 / 4) × 16

                                                = 4 slices of pizza

Hence, Tiffany ate 4 slices of pizza.

96% of all air travel departs on time. If you are taking 3 flights in one day, what is the probability that all of them depart on time?

Answers

Answer:  0.884736

Step-by-step explanation:

Given: The proportion of all air travel departs on time: p= 0.96

Total flights : n= 3

Let x be the number of flights on time.

As there are two cases either flight on time or not, so it is a binomial case.

Binomial distribution formula: [tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex]

The probability that all of them depart on time = [tex]P(X=3)=\ ^3C_3(0.96)^3(1-0.96)^0=(1)(0.96)^3=0.884736[/tex]

The probability that all of them depart on time = 0.884736

When an article is sold at a discount of 10 %, a profit of Rs 8 is earned. If the same
article is sold without allowing a discount, there will be a profit of Rs 20. Find the cost price of the article.​

Answers

Answer:

Market Price = MP

Cost Price = CP

P1 = (MP - 10%) - CP = Rs8

- CP = Rs8 - 0.90% MP

CP = 0.90 MP - Rs8

P2 = MP - CP = Rs20

- CP = Rs20 -MP

CP = MP - Rs20

0.90 MP - Rs8 = MP - Rs20

- 0.10% MP = - Rs12

0.10% MP = Rs 12

MP = Rs120p

CP = MP - Rs20 = Rs120 - Rs20 = Rs100.

The cost price of the item is Rs100.
