2755

12.75

0.151

Step-by-step explanation:

Given :

21.1 + 45.99 + 26.0 = 93.09

15.55 + 21.61 - 12.333 = 24.827

14 + 0.8 + 9.33 = 24.13

14.5 * 190 = 2755

5.1 * 2.5 = 12.75

A point is in Quadrant 3 and on the unit circle. If its x-coordinate is -4/5, what is the y-coordinate of the point?

Answers

Answer:

The y-coordinate of the point is -3/5

Step-by-step explanation:

Here, we want to get the y-coordinate of the point

when we talk of the unit circle, we mean a circle that has its radius equal to just 1 unit

Now, on the third quadrant, we have the x axis value as negative, and also the y axis value as negative

In the unit circle, the Pythagoras’ theorem works for all quadrants; with the radius representing the hypotenuse of the right triangle, the x and y coordinates value represents the other sides of the triangle

Mathematically, from the theorem;

the square of the hypotenuse (radius of the unit circle) equals the sum of the squares of the two other sides

Thus, we have it that;

1^2 = (-4/5)^2 + y^2

1 = 16/25 + y^2

y^2 = 1 - 16/25

y^2 = 9/25

y = √(9/25)

y = +3/5 or -3/5

But since the y-coordinate value is supposed to be negative, we have to choose y = -3/5 as our answer (for the third quadrant)

5 folders and 5 pens = yes

6 pens and 6 erasers = yes

1 pen and 4 notebooks = no

3 folders and 7 erasers = no

4 folders and 2 notebooks = yes

Step-by-step explanation:

Max total = $10

(5 folders x 1.29) + (5 pens x 0.70)

6.45 + 3.50 = 9.95

(6 pens x 0.70) + (6 erasers x 0.89)

4.20 + 5.34 = 9.54

(1 pen × 0.70) + (4 notebooks × 2.35)

0.70 + 9.40 = 10.10

(3 folders × 1.29) + (7 erasers × 0.89)

Determine this one algebraically

Answers

Answer:

x = 5

y = 5

Step-by-step explanation:

In this question you need to solve one equation in order to plug the value into the second one and solve it as well. Lets start with the top one...

2x - x = 5

1x = 5

x = 5

Now we plug that value of x into the second equation

4x - 2y = 10

4(5) - 2y = 10

20 - 2y = 10

-2y = -10

y = 5

Finally, we can see that both x and y have a value of 5.

Rs. 1000

Step-by-step explanation:

Let the marked price is x

Discount 4% ⇒ x - 4% = 0.96xCP = Rs. 800 Profit after discount = 20%SP = 800 + 20% = 800*1.2 = Rs. 960

Now we have below equation:
