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?
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)

Answer:
F
Step-by-step explanation:
she spins it 2 times and there's 4 different spinners on the board
there's 1 * on the board so
* = 1/4
there's 1 & on the board so
& = 1/4
its 1/4 for both
so 1/4 + 1/4 = 2/8 or .25
2/8 = 1/4

AFTER allowing 4 % discount on the marked price of an article there is a profit of 20 % if the cost price of the article is RS 800 find marked price ? plz plz plz plz plz saw plz
Answer:
Rs. 1000Step-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. 960Now we have below equation:
0.96x = 1.2*8000.96x = 960x = 960/0.96x = 1000MP is Rs. 1000

please help. thanks.
Determine this one algebraically
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.

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
0.15 ÷ 0.991 = 0.151

Answer:
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)
3.98 + 6.23 = 10.21
(4 folders × 1.29) + (2 notebooks × 2.35)
5.16 + 4.70 = 9.86
