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.

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.

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.

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]

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.

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.
