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.

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

Answer:

26741 and 12

Step-by-step explanation:

(1)

The area ( A) of a rectangle is calculated as

A = length × width , then

A = 221 × 121  = 26741

(2)

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] × base × height , then

A= [tex]\frac{1}{2}[/tex] × 8 × 3 = 4 × 3 = 12

Answer:

(i) David ha empleado [tex]\frac{2}{3}[/tex] de la cartulina.

(ii) Angie ha empleado [tex]\frac{2}{7}[/tex] de la cartulina.

(iii) David ha usado más cartulina.

Step-by-step explanation:

El problema indica que David y Angie emplean una cartulina del mismo tamaño cada uno. David corta la suya en 3 pedazos iguales, mientras que Angie obtiene 7 pedazos iguales. Finalmente, cada uno emplea dos de sus pedazos. A continuación, respondemos a las preguntas del enunciado:

(i) ¿Qué fracción de cartulina ha usado David?

La fracción de cartulina empleada por David es igual a los pedazos utilizados divididos por el total de pedazos. Esto es:

[tex]x = \frac{2}{3}[/tex]

David ha empleado [tex]\frac{2}{3}[/tex] de la cartulina.

(ii) ¿Qué fracción de cartulina ha usado Angie?

Aplicando el mismo procedimiento del punto anterior, tenemos que:

[tex]x = \frac{2}{7}[/tex]

Angie ha empleado [tex]\frac{2}{7}[/tex] de la cartulina.

(iii) ¿Quién ha usado más cartulina?

La persona que ha usado la mayor cantidad de cartulina es aquella que tiene el menor denominador. Por tanto, David ha usado más cartulina.

Answer:

1. The time it would take Inex to run 1 mile is 5 minutes 20 seconds

2. Great has the fastest (lowest) time

3. When running a mile Great is faster than Inex by 20 seconds

Step-by-step explanation:

1. The distance Great ran in 5 minutes = 1 mile

The distance Inex ran in 1 minute and 20 seconds = A quarte mile = (1/4) mile

We note that 1 minute and 20 seconds = 4/3 minutes

Given that the time Inex ran 1/4 mile = 4/3 minutes...(1)

We have;

The time it would take Inex to run 1 mile is given as follows;

1 = (1/4) ÷ (1/4)

1 mile = ((1/4) ÷ (1/4)) mile = (1/4) mile/(1/4)

The time to run 1 mile = The time to run (1/4) mile/(1/4) = 4/3 minutes/(1/4) (by dividing both sides of equation (1) by (1/4),

4/3 minutes/(1/4) = 4 × 4/3 minutes = 16/3 minutes = [tex]5\frac{1}{3}[/tex] minutes= 5 minutes 20 seconds

The time it would take Inex to run 1 mile = 5 minutes 20 seconds

2. Given that Great ran a one mile race in 5 minutes, and Inex ran the same one mile race in 1 minute and 20 seconds, Great has the fastest (lowest) time

3. The amount faster Great's time is faster than Inex's time to run one mile = 5 minute 20 seconds - 5 minutes = 20 seconds.

Answer:

$719.72

Step-by-step explanation:

Answer:

Step-by-step explanation:

Line AB is parallel to line CD (k) so they have the same slope.

slope=m=(y2-y1)/(x2-x1)

m=(6-0)/(4-0)

m=6/4=1.5

y=mx+b, we know m=1.5 so

y=1.5x+b, and we know it passes through point (4,0) so we can solve for b

0=1.5(4)+b

0=6+b

b=-6 so line k is

y=1.5x-6

Answer:

x = 75 hope this helped

Step-by-step explanation:

The true solution to the equation is,

⇒ x = 75

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]

Now, We can simply as;

⇒ [tex]2 ln e^{ln2x} - ln e^{ln10x} = ln 30[/tex]

⇒ 2 ln 2x - ln 10x = ln 30

⇒ ln (2x)² - ln 10x = ln 30

⇒ ln (2x)² / 10x = ln 30

⇒ 4x² / 10x = 30

⇒ 4x = 300

⇒ x = 75

Thus, The true solution to the equation is,

⇒ x = 75

Answer:

2^4/4^2 will be 1, I will explain after answering,

2 x 3^1 = 6

(4 - 2) ^2 = 4

First. Evaluate the exponents in the fraction above

2 x 2 x 2 x 2 = 16

4 x 4 = 16

and 16 over 16 would equal 1 whole

3 to the power of 1 means just 3 so 2 x 3 = 6 (easy multiplication)

Evaluate in the parenthesis first: 4 - 2 = 2 then 2 to the power of 2 would be   2 x 2 = 4

Answer:

n = - 6

Step-by-step explanation:

Given k(x) then k(x) + n is a vertical translation of k(x)

• If n > 0 then a shift up of n units

• If n < 0 then a shift down of n units

Here k(x) has been shifted from (0, 0 ) to (0, - 6 )

That is a shift down of 6 units, then

p(x) = k(x) - 6

That is n = - 6

The second equation is equivalent to the first one.

In other words, two equations carry the same information as the first one, not more.
