Answer:
a) 8
b) 41
c) 39
Step-by-step explanation:
a) 8 workers
b) 41 years old
c) 39 years old
How many workers are over 40 years old ?
There are 4 rows in the diagram, from which, all the workers of last two rows are over 40 years old.
Ages of workers in last two rows are 41, 42, 44, 46, 47, 48, 53, 59
Total no. of workers over age 40 is 8
What is the median age of an office worker ?The ages of workers are 23, 25, 34, 35, 38, 38,39, 41, 42, 44, 46, 47, 48, 53, 59
The median will be the 8th term ,i.e. 41 years old
What is the new median ?If oldest (59 yrs age) worker retires and is replaced by a 24 years old.
Then the ages are 23, 24, 25, 34, 35, 38, 38,39, 41, 42, 44, 46, 47, 48, 53, 59
The new median will be 8th term, i.e. 39 years old

Answer:
x = 13
Step-by-step explanation:
Use pythagorean theorem since you have a right angle. So [tex]c^{2} = a^{2} + b^{2}[/tex]
so in this case [tex]c^{2} = 5^{2} + 12^{2}[/tex] so c = [tex]\sqrt{25+144}[/tex] and c = [tex]\sqrt{169}[/tex] so c = 13
Pentagon MNPQR is shown on the coordinate grid. Pentagon MNPQR is dilated with the origin as the center of dilation using the rule (x,y) —> (1/4 x, 1/4y) to create pentagon M’N’P’Q’R
Read each statement below
if it is TRUE, circle GREEN, if it is FALSE, circle Red
Pentagon M’N’P’Q’R is larger than pentagon MNPQR, because the scale factor is greater than 1
Pentagon M’N’P’Q’R is smaller than pentagon MNPQR, because the scale factor is less than 1.
Pentagon M’N’P’G’R is smaller than pentagon MNPQR, because the scale factor is greater than 1

Answer:
Option (2)
Step-by-step explanation:
If a polygon is dilated by a scale factor = k
Rule to be followed,
(x, y) → (kx, ky)
Here, k = Scale factor
If 0 < k < 1, size of the image will be reduced.
If k > 1, size of the image will be enlarged.
Pentagon MNPQR is dilated with the origin as the center of dilation to form an image M'N'P'Q'R'.
Rule used for the transformation,
(x, y) → [tex](\frac{1}{4}x,\frac{1}{4}y)[/tex]
Here, scale factor by which MNPQR has been dilated is [tex]\frac{1}{4}[/tex]
Since, scale factor is between 0 and [tex]\frac{1}{4}[/tex], size of M'N'P'Q'R' will be reduced.
Therefore, size of pentagon M'N'P'Q'R' will be smaller than pentagon MNPQR.
Option (2) will be the answer.

What is the difference between solving this equation: x - 4 = 17 AND this equation : 5x - 1 = 24 ?
Answers
Answer: See explanation
Step-by-step explanation:
x - 4 = 17
Collect like terms to get the value of x
x = 17 + 4
x = 21
5x - 1 = 24
Collect like terms to get the value of x
5x = 24 + 1
5x = 25
Divide both side by 5
5x/5 = 25/5
x = 25/5
x = 5
I NEED HELP!!! ASAP!!!
Answers
Answer:
A.
Step-by-step explanation:
In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D
It isn't a gradual line, as 6x is, so that is eliminated.
When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times. If you then connect the dots, it will be a line probably very close to your estimate.
Porfavor: Elabora un problema matemático relacionado con tu vida cotidiana donde utilices “adición y sustracción de números con signo” y el resultado sea - 9
Answers
Answer:
Queremos hacer un problema donde tengamos adición (a + b) y substracción ( a - b) de números con signo, de tal forma que el resultado final sea 9.
El caso más simple para este tipo de problemas es algo como:
"Vas a un mercado a comprar un par de productos, el producto A cuesta $A, y el producto B cuesta $B, si solo tenés un billete de $C, cuanto será el vuelto?"
Bueno, el vuelto va a ser la diferencia entre lo que vos entregáis, $C, y el costo total de los productos que compras ($A + $B)
Entonces el vuelto va a ser:
vuelto = $C - ($A + $B)
Y queremos que el resultado de este problema sea 9, entonces podemos escribir:
vuelto = $9 = $C - ($A + $B)
Ahora debemos encontrar los valores de las incógnitas.
Podemos simplemente definir dos de ellas y encontrar la tercera, por ejemplo si $C = $20 y $A = $2, entonces:
$9 = $20 - ($2 + $B)
$9 = $20 - $2 -$B
$9 = $18 - $B
$9 - $18 = -$B
-$9 = -$B
Entonces $B será = $9.
Y el problema podría escribirse como:
"Vas a un mercado a comprar un par de productos, el producto A cuesta $2, y el producto B cuesta $9, si solo tenés un billete de $20, cuanto será el vuelto?"
