if a pen is sold at rupees 8 with a loss of 20% find it cost price......plz tell me.....
Answer:
Step-by-step explanation:
SP of a pen =rs 8
loss%=20%
let cp be x
SP=CP-loss%*CP
8=x-20/100*x
8*100=100x-20x
800/80=x
10=x
Jay organised a large wedding and 1/3 of them chose beef 5/12 of them chose Chicken and 69 of them chose vegetarian so how many guest were at the wedding ?
Answer:
276 Guests
Step-by-step explanation:
Calculation to determine how many guest were at the wedding
Guests that choose beef =1/3
Guests that choose chicken= 5/12
Guests that choose vegetarian=69
Now let calculate the how many guest were at the wedding
Let x represent the numbers of guest that were present at the wedding
Hence,
x/3 + 5x/12 + 69 = x
9x/12 + 69 = x
12x/12 - 9x/12 = 69
3x/12 = 69
x/4 = 69
x=69*4
x = 276 guests
Therefore the numbers of guests that were at the wedding is 276
Answer: 276
Step-by-step explanation: Let “x” be the number of guest.
1/3 x +5/12x + 69 = x Simplifying and solving for x … where x = 276
1/3(276) + 5/12(276) + 69 = 276
92 + 115 + 69 = 276
What is the probability of rolling a pair of dice and not rolling the same number?
Answer:
5/6
Step-by-step explanation:
The "first" dice can land on any number, so there are 6 choices. The "second" can not be the same number as the first one. So there are 5 choices. We multiply to get 6*5=30 ways to roll a different number. There are 6*6 total ways so the probability is 30/36 which simplifies to 5/6.

How much farther do runners run from the start to the water station than from the water station to the finish? 0.26 km 0.35 km 0.45 km 1.35 km
Complete question :
Runners participating in a charity event will run 2.1 km from the starting point to a water station and then run 1.75 km to the finish, as shown in the diagram below.
How much farther do runners run from the start to the water station than from the water station to the finish?
Answer:
0.35 km
Step-by-step explanation:
From start to water station = 2.1 km
From water station to finish = 1.75 km
Difference in distance = farther distance covered = (2.1 km - 1.75 km) = 0.35 km

The dot plots below show the test scores of some mathematics students and some science students: Two dot plots are shown one below the other. The top and the bottom plots have the title Mathematics Students and Science Students respectively. Below the line for each dot plot is written Mark. The markings on each line are from 30 to 50 at intervals of 1. For the top plot there are two dots each for 34 and 40 and 1 dot each for 32, 33, 35, 37, and 39. For the bottom plot there are 2 dots each for 43, 46 and 49 and 1 dot each for 41, 42, and 47. Based on visual inspection of the dot plots, which group of students appears to have the larger average score? The mathematics students The science students Both groups are similar. Not enough information is available to draw a conclusion.
Answer:
I believe the Science Students have a higher average grade on their respective tests.
Step-by-step explanation:
The mathematics students all scored between 30-40 on their test while the science students scored between 40-50%. This shows that the science students had a larger average score. Hope this helps! Have a great day :)

Answer:
x=2, y = -4.
or as an ordered pair it is (2, -4).
Step-by-step explanation:
-x + 6y = -26
x + 5y = -18 Add these 2 equations to eliminate x:
0 + 11y = -44
y = -44/11 = -4.
Now substitute y = -4 in the first equation:
-x + 6(-4) = -26
-x - 24 = -26
-x = -26 + 24 = -2
x = 2.
Check the result by substituting in equation 2:
x + 5y = 2 + 5(-4) = 2 - 20 = -18 - checks out.

Answer: y=5/3x-4
Step-by-step explanation:
Hi, you could find the slope with any 2 points on the line. For accuracy, I will choose the points (6, 6) and (0, -4), meaning when x =6, y=6, and when x=0, y=-4. Then you can set up an equation. Because the line on this graph is linear (meaning straight), the form of the equation would be y=ax+b. (If it was a parabola, it would be y=ax^2+bx+c).
y=mx+b (Or some people prefer y=ax+b, but the same thing).
Now, plug in the x and y values, getting:
6 = 6m+b and -4=0*m+b
When you simplify, you will get that b is -4, and then m is 5/3
So the equation is y=5/3x-4
You can plug the numbers of x and y in to check your answer.
Hope this helps!

angle A is 63 since 27+90= 117, 180-117= 63 (since a straight line is 180°)
2. 7x + 10 = 150 (since they are vertical angles)
7x = 140
x = 20

Step-by-step explanation:
Write the number using scientific notation:
23,000
The scientific notation representation of 23,000 is 2.3 x 10⁴
To express the number 23,000 in scientific notation, we need to move the decimal point to create a number between 1 and 10, and then multiply it by a power of 10.
Starting with 23,000, we can move the decimal point to the left four places to get 2.3. This means we divided the original number by 10,000 (10⁴). To compensate for this division, we multiply 2.3 by 10,000 in the form of 10⁴.
Thus, the scientific notation representation of 23,000 is 2.3 x 10⁴. The coefficient (2.3) is between 1 and 10, and the exponent (4) indicates the number of decimal places the original number was moved.
