Answer: 45
Step-by-step explanation:
18 = 40% N
18 = 0.4 N
Divide both sides by 0.4
N = 45
There are 45 students want to be rescued.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Eighteen students decide they don't want to be rescued and want to continue to live in the jungle.
And, This represents 40% of the students.
Now,
Let the number of students want to be rescued = x
So, We can formulate;
⇒ 40% of x = 18
Solve for x as;
⇒ 40/100 × x = 18
⇒ 40x = 1,800
⇒ x = 1800/40
⇒ x = 45
Thus, The number of students want to be rescued = 45

Write the slope-intercept form of the equation of a line with a slope of -5/8 that passes through the point (-14,6)
Answer:
y = -5/8x - 11/4
Step-by-step explanation:
Since we already know the slope which is -5/8. This will be the m in the equation.
To find the y-intercept, plug the coordinates into the equation, which is
y= -5/8 + b
6 = -5/8(-14) + b
6 = 35/4 + b
= -11/4 = b

The value of x is 3 in the triangle.
What is Trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
By pythagoras theorem we find the value of x.
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides
x²+x²=(3√2)²
2x²=9×2
2x²=18
Divide both sides by 2
x²=9
Take square root on both sides
x=3
Hence, the value of x is 3 in the triangle.

Answer:
Slope: 1
Step-by-step explanation:
(9,0) and (0, -9)
m= (y2-y1)/(x2-x1)
m= (-9 - 0)/ (0 - 9)
m= (-9)/(-9)
m = 1
Answer:
Solution given:
coordinates are
(x1,y1)=(9,0)
(x2,y2)=(0,-9)
we have
Slope =[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] = \frac{ - 9 - 0}{0 - 9} [/tex]=1

1) Since the two triangles are similar, corresponding parts are similar (CPSP - corresponding parts of similar polygons)
2) Since the corresponding sides are similar, [tex]\frac{AX}{AB} = \frac{XY}{BC}[/tex]
3) We know that AX is 12, AB is 20 (AX+XB=12+8 because of pwp -> part whole postulate), XY is 17, and BC is x
4) Substitute these values into the equation from step 2
[tex]\frac{12}{20} = \frac{12}{x}[/tex]
5) Cross-multiply to get 12x = 12(20)
6) Solve
12x = 240
x = 20
