Answers

Answer:

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.

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.

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.

Find the equation of the line shown.

Answers

Given : A graph of linear equationis given to us.

To Find : The equation of the line .

Solution : Here we can see that the line passes through points ( 1 , 2 ) and ( 2 , 4). So , clearly here we can use Two - point form to find the equation of the line .

So , first point will be , ( 1 , 2 ) & second point will be ( 2 , 4 ) . So here ;

[tex]\sf x_1 = 1\: \& \:y_1 = 2[/tex][tex]\sf x_2 = 2\: \&\: y_2=4[/tex]

Now , the two point form formula is :

[tex]\Large\boxed{\red{\sf \purple{\mapsto} y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)}}[/tex]

[tex]\tt:\implies y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1) [/tex]

[tex]\tt:\implies y-2=\dfrac{4-2}{2-1}(x-1) [/tex]

[tex]\tt:\implies y-2 = \dfrac{2}{1}(x-1) [/tex]

[tex]\tt:\implies y-2=2(x-1)[/tex]

[tex]\tt:\implies y -2 = 2x - 2 [/tex]

All perfect squares are divisible by 2.
A.) true
B.) False, counterexample of 16
C.) False, counterexample of 15
D.) False, counterexample of 25

Answers

Answer:

the correct answer is C

Step-by-step explanation:

because the square root of 15 is 3.8 and 3.8 isnt divisible by 2

D. False, counter example of 25.
The reason for that is because A is not true, B is not a counterexample, C is not a square, so D is the answer.

Data Set A has a mean of 215 and a standard deviation of 35. Data Set B has a mean of 400 and a standard deviation of 12.
Which data set is more spread out?

Answers

Answer:

Data set A

Step-by-step explanation:

Data set A is the one that is more spread out.

The mean is the same as the average of a given sample. It is usually a measure of the central tendency of a data set.

Standard deviation is a measure of the spread of a given set of data.

The lower the value of the standard deviation, the more clustered around the mean a data is. Data is spread out if it has a higher value of standard deviation.

Since data set A has a standard deviation of 35, it the most spread out.

Wilson paints 40% of a bookcase in 20 minutes.

How much more time will it take him to finish the bookcase?

Answers

Answer:

30 minutes

Step-by-step explanation:

The percentage rises up by 40% every 20 minutes and if we divide that in half he paints 20% in 10 minutes. Wilson needs to paint 60% more of the bookcase. 40% plus 20% is 60%. So we just add 20 with 10 to get 30 minutes.
