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
Eighteen students decide they don't want to be
rescued and want to continue to live in the
jungle. If this represents 40% of the students,
how many students want to be rescued?
Type your answer into the box to continue.
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

Given:
A box-and-whisker plot of data set.
To find:
The percentage of the data values that are greater than 80.
Solution:
From the given box-and-whisker plot, it is clear that:
Minimum value = 8
First quartile = 60
Median = 68
Third quartile = 80
Maximum value = 92
We know that the 25% the data value are greater than or equal to third quartile because the third quartile divides the data in 75% to 25% and 80 is the third quartile.
Therefore, about 25% of the data values that are greater than 80.

David y Angie tienen dos cartulinas iguales. David corta la suya en 3 trozos iguales y Angie la corta en 7 trozos. Los dos usan 2 de sus trozos para hacer un muñeco. Que fracción de cartulina ha usado David?¿Y Angie?¿Quien ha usado mas cartulina? Alguien me lo dice por fa es que no lo entiendo
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:
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
In the diagram, △ABC∼△CDE. Write an equation for line k
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

which three statements are true about the line segment CB
it's the radius of the circle
it is the circumference of the circle
it is a cord
it is 6cm long
it is diameter of the circle
it is 7cm long
it is 1.75cm long
Answer:
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
Step-by-step explanation:
Here, we want to select three statements that are true about CB
From what we have, CB runs from one edge to the other, passing through the center of the circle
Also, as we can see, AD is a radius as it is the distance from the center of the circle to the circumference; CB is twice this as it is the diameter
The diameter is a chord that passes through the center of the circle and it is a radius
So let us select the correct statements;
1. it is 7 cm long
2. it is a chord
3. it is the diameter of the circle
