3. In a certain school, there are 456 girls. Calculate the total number of students

marin [14]

Answer:

3) girls = 24% = 456

let the total number of students be = x

$\frac{24}{100} \times x = 456$

$x = 456 \times \frac{100}{4}$

$x = 1900$

the total number of students is 1900

4) increase = 20%

new salary = 24000 rupees

let his original salary be = y

$\frac{20}{100} \times y = 24000 - y$

$0.2y = 24000 - y$

$0.2y + y = 24000$

$1.2y = 24000$

$y = \frac{24000}{1.2}$

$y = 20000$

his original salary is 20,000 rupees

I need help solving this

Stolb23 [73]

Step-by-step explanation:

So in the equation given, y = 2x - 3

you substitute x for whats given in the table in the x column.

Example

In the graph the first number under the x colum is -1.

y = 2x - 3 in the equation you take out x and put -1.

So now the equation becomes y = 2 × -1 - 3.

Using bedmas to solve the question you should get -5

Which now means y = -5

To plot the point now x would be -1 and y would be -5 (-1, -5)

Same thing for the second number in the x Column.

y = 2 × 1 - 3 which equals -1

To plot it

x = 1 y = -1. (1, -1)

And for the last number 3.

Agai. You substitute x for 3 which makes the equation y = 2 × 3 - 3

this gives you 3 and to plot it

x would be 3 and y would be 3

Line AB intersects line CD at point F, with a ray FE forming a right angle EFB. What angle relationship best describes angles AF

vova2212 [387]

Based on the positions of angles AFC and EFC, the relationship between them is a Complimentary angle.

<h3>How are AFC and EFC related?</h3>

Angles AFC and EFC are complimentary angles because complimentary angles are angles that add up to 90 degrees.

Looking at the shape, Line FC divides the right angle to create angles AFC and EFC so when these are added together, they equal 90 degrees.

In conclusion, angles AFC and EFC are complimentary.
