Answer:
The total number of students is 3,000.
Step-by-step explanation:
Given that of the total number of candidates in an examination, 40% fail in first subject, of the rest 10% fail in the second and of those that pass in these two subjects, only 75% pass in the remaining subject, knowing that the number of unsuccessful candidates exceeds that of that of successful by 570, to find the total number of students the following calculation must be performed:
40 + (60 x 0.1) = 46
54 x 0.75 = 40.5
40.5% pass the 3 exams, while the remaining 59.5% do not.
59.5 - 40.5 = 19
19% = 570
570/19 = 30
30 x 100 = 3000
Thus, the total number of students is 3,000.

Answer:
[tex] \sqrt{50x^2} [/tex]
[tex] \sqrt{72x^2} [/tex]
Step-by-step explanation:
Simplify each given options as much as possible to see which of them has a result that is like a radical.
Option 1: [tex] \sqrt{50x^2} [/tex]
[tex] \sqrt{25*2*x^2} = 5x\sqrt{2} [/tex]
This is like a radical
Option 2: [tex] \sqrt{32x} [/tex]
[tex] \sqrt{16*2*x} = 4\sqrt{2x} [/tex]
This is NOT like a radical
Option 3: [tex] \sqrt{18n} [/tex]
[tex] \sqrt{9*2*n} = 3\sqrt{2n} [/tex]
This is NOT like a radical
Option 4: [tex] \sqrt{72x^2} [/tex]
[tex] \sqrt{36*2*x^2} = 6x\sqrt{2} [/tex]

The original price of the Kindle is $269.99.
If the Kindle was 15% off, what is the discounted price of the Kindle?
Answer:
229.4915
Step-by-step explanation:
you first find 15% of $269.99 which is 15/100 * 269.99
which is 40.4915
and since you are finding the discounted price
you subtract 40.4915 from 269.99
= 269.99-40.4915
=229.4915
dont forget to put the unit ($)
=$229.4915
6x-6y=23 find y when x=8
Answer:
y= 4.166
If rounded to the nearest tenth
y = 4.2
Step-by-step explanation:
6x - 6y = 23
x = 8
6x - 6y = 23 (Sub in the x with 8)
6(8) - 6y = 23
48 - 6y = 23 (Subtract each side by 48)
-6y = 23 - 48
-6y = -25 (Divide each side by -6)
y = 4.166
If rounded to the nearest tenth
y = 4.2

Pet plus sells 12 cans of dog food for $9.60 . What is the price per can?
Answer and Step-by-step explanation:
To find the amount of dollars per can of dog food, we divide the price by the amount of cans bought.
9.6 divided by 12 equals 0.8.
$0.8 is the answer.
What is the slope of a line that is perpendicular to the line 2y - 3x = 8?
Answer: -2/3
Step-by-step explanation:
The slope intercept form of that equation is y=(3/2)x+4, so the slope is 3/2.
To find the perpendicular slope, you need to find the opposite reciprocal. The reciprocal of 3/2 is 2/3, the opposite of 2/3 is -2/3
Answer:
- 2/3
Step-by-step explanation:
You are given the line 2y-3x=8 which could also be written as 2y=3x+8
First you have to solve that and end up with a solid y so you do 2/2y=(3/2)x+8/2 which is y=(3/2)x+4
In that form of a line the number next to the x its the slope so the slope its 3/2
In perperndicular lines to find the slope you have to do S1*S2= -1... (S=slope)
So... 3/2*S2= -1 and now you have to leave S2 alone to solve it so you divite it by 3/2 and you end up having
S2= -2/3
And thats the slope for the perperndicular line to 2y-3x =8
A store pays $365.84 for a fountain. The store marks up the price by 10%.
What is the amount of the mark-up?
Round your answer to the nearest cent: $
Answer:
The store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.
Step-by-step explanation:
Given that a store pays $ 365.84 for a fountain, and then the store marks up the price by 10%, to determine the amount of the mark-up the following calculation must be performed:
365.84 x 10/100 = X
3,658.4 / 100 = X
36,584 = X
36.584 + 365.84 = 402.424
Thus, the store marks up the fountain by adding $ 36.58 to its original cost, bringing its retail price to $ 402.42.

Help tell me how Pi is found
Answer:
The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi. Leaving them with a infinte number 3.14159... and so on.
Step-by-step explanation:
Answer:
How was Pi discovered?
Here's a brief history of finding π. The ancient Babylonians calculated the area of a circle by taking 3 times the square of its radius, which gave a value of pi = 3. One Babylonian tablet (ca. 1900–1680 BC) indicates a value of 3.125 for π, which is a closer approximation.
How is PI value calculated?
In some ways Pi (π) is a really straightforward number – calculating Pi simply involves taking any circle and dividing its circumference by its diameter. In fact if you search long enough within the digits of Pi (π) you can find any number, including your birthday.
Step-by-step explanation:
The radius of a circle is 19 in. Find its area in terms of .
Find the coordinates of the point of intersection of all parabolas that have equation y=x2+px +q with p+q=2020. The point of intersection is
Answer:
(1,2021)
Step-by-step explanation:
P and q can vary subject to their sum being 2020.
Consider one parabola with p1 and q1 and another with p2 and q2.
y1=(x1)^2+(p1)(x1)+(q1)
y1=(x2)^2+(p2)(x2)+(q2)
At their intersection, the x and y coordinates are the same.
y1=y2=y
x1=x2=x
x^2+(p1)x+(q1)=x^2+(p2)x+(q2)
Solve for x
x(p1-p2)=q2-q1
x=(q2-q1)/(p1-p2)
Use the constraint that p+q=2020 to eliminate p1 and p2.
p1=2020-q1
p2=2020-q2
x=(q2-q1)/(2020-q1-2020+q2)
x=(q2-q1)/(q2-q1)
x=1
Substitute in the equation for y.
y=1^2+p(1)+q
y=2021

Step-by-step explanation:
An angle measures 12°. Find its complement. Do not include units in your answer.
Answer:
78
Step-by-step explanation:
complements = 90
x + 12 = 90
-12. -12
× = 78
If two angles are complementary,
then the sum of their measures is 90 degrees.
If two numbers add to 90, we can represent those numbers as x and 90 - x.
So we will call one of our angles x and its complement as 90 - x.
So we have 90 - 12 which is 78.
So the complement of a 12° angle is a 78° angle.
The measure of the angles in a triangle ABC are given by the expression in the table. Please Help
There is the question^^

x = 25 degrees
