Answer:
La edad actual de Juan es 34 años y la de su padre es 70 años.
Step-by-step explanation:
De acuerdo a la información proporcionada, puedes decir que la edad del padre de Juan más 2 años es igual a dos veces la edad de su hijo, lo que se puede escribir de la siguiente forma:
x+2=2(y+2), donde: x es la edad del padre de Juan y y es la edad de Juan
x+2=2y+4
x=2y+4-2
x=2y+2 (1)
Además, dado que se menciona que hace 16 años el padre tenía el triple de la edad de Juan, puedes decir que la edad del padre de Juan menos 16 años es igual 3 veces la edad que tenía Juan:
x-16=3(y-16) (2)
Ahora puedes reemplazar (1) en (2):
2y+2-16=3y-48
2y-14=3y-48
-14+48=3y-2y
y=34
Finalmente, puedes reemplazar el valor de y en (1)
x=2(34)+2
x=68+2
x=70
De acuerdo a esto, la respuesta es que la edad actual de Juan es 34 años y la de su padre es 70 años.

1. An island is considering adding another character to their vehicle license plates in order to increase the
number of license plates available. Currently, a license plate must have exactly four-character spaces. Each
character space may be filled with any capital letter other than I, B, Z, or O or any number between, and
including 0 to 9. Letters and numbers may repeat on the plates.
(a) How many different license plate numbers are available under the current structure of exactly four
characters per plate?
Please show all steps and work! Thank you!
Step-by-step explanation:
so 26 minus 4 is 22 for letters so 22 times 22 times 22 times 22 and thats for letters and for numbers its 10 x 10 x 10 x 10 i dont really umderstand the question but you can have 244256 possible license plates there
In ΔXYZ, ∠X=59° and ∠Y=21°. ∠XWZ=90° and XY=6.1. Find the length of XW to the nearest 10th.
Answer:
this is question is wrong it you typed it wrong
how come the triangle named XYZ and the angle wxz and if there 2 triangles one must be a failure because there is no triangle which all his angels equals more than 180°
look again and if possible take a picture of the question
can someone pls explain how to solve problems like this?? ty
Answer:
hi so basically you find area the way you normally would, length width etc, and then you also find the area of the triangle inside and subtract that amount from the area you first got from the rectangle. sorry if this doesn't make sense, good luck!
Step-by-step explanation:
The student who traveled to states visited new states during a vacation. Does increasing the to change the median? If so, how?
Step-by-step explanation:
The exact question is as follows :
Given - The student who traveled to 3 states visited 6 new states during a vacation.
To find - Does increasing the 3 to 6 change the median? If so, how?
Proof -
Yes,
If we increase the 3 states to 6 states, it changes the median
Because
The median of the first 3 states is the middle state.
For example -
If we have 3 states X, Y, Z
Then the median is the state Y
Now,
The median of 6 states is the average of the 2 middle states.
For example -
If we have 6 states
X, Y, Z, U, V, W
Then
The median is not explicit.
Median is the average of the two middle states, Z and U.
And
Average of Z and U = half of the sum of Z and U.
i.e. (Z + U)/2.
And we can see that,
Median of 3 States is not equal to Median of 6 states
i.e. Y is not equal to (Z + U)/2.
So,
We can say that,
Increasing the state 3 to 6 changes the median.
According to the weather
forecast, the probability
that it will rain on
Wednesday is 0.85. What
is the probability that it
will not rain?
Answer:
0.15
Step-by-step explanation:
1.00 - 0.85 = 0.15
Answer: .15
Step-by-step explanation: The reason being is if .85 is equal to 85 % then there is only 15 % left so the answer is .15
The relationship between the number of years (x) that have passed and the population (y) for a small town is shown in the table.

Population (y)
1,440 1,728 2,074 2,488 2,986 3,583 4,300 5,160
A regression equation for this data is y = 1, 200(1.2).
Answer:
D. 10,699
Step-by-step explanation:
The given data for the Population Count Per Year is presented as follows;
Number of Years (x); 1, 2, 3, 4, 5, 6, 7, 8
[tex]\begin{array}{ccccccccc}Number \ of \ Years \ (x)&1&2&3&4&5&6&7&8\\Population \ (y)&1,440&1,728&2,074&2,488&2,986&3,583&4,300&5,160\end{array}[/tex]The data regression equation is y = 1,200·(1.2)ˣ
Based on the regression equation for the data, the predicted value of the town's population after 12 years is given by substituting x = 12 as follows;
After 12 years, y = 1,200 × (1.2)¹² ≈ 10,699.32
Therefore, the option which is the best prediction is 10,699.

A park charges $45 to enter and $0.75 per game. Write an algebraic expression to represent the total amount paid by a guest.
Answer:
y = 0.75x + 45
Step-by-step explanation:
x would be the amount of games played and y would be the total money spent.
Answer:
y= 0.75x+45
Step-by-step explanation:
y= total amount paid by guest
x = # of games
0.75 x = $0.75 paid per game
45= minimum charge of 45 to enter park

Answer:
$5.30
Step-by-step explanation:
23.85/9=$2.65
2.65*2=$5.30
Answer:
I don't know if this is right but I got $5.30.
Step-by-step explanation:
I did 23.85/9 to get how much each pane is than I multiplied by 2 to get the cost of the 2 new panes.
23.85/9= 2.65
2.65*2 = 5.3

How are finding the volume of a rectangular prism and a triangular prism alike
Answer:
the triangular prism is ⅓ the size of the rectangular prism. they have the same concept equation of:
rectangular prism - length×width×height
triangular prism - ½×length×width×height
they both have to multiply the base and height to find the volume
Answer:
Finding the volume of a rectangular and triangular prism are alike, one way is they use similar formula base x length x height. Another way is They both have rectangle in the prism.

Jillian's puppy weighed 16 pounds at the age of 2 months. It weighed 60 pounds at the age of 8 months. What is the percent change in the puppy's weight?
Answer:the percent change in the puppy's weight= 275%
Step-by-step explanation:
Jillian's puppy Weight at 2 months =16 pounds
Jillian's puppy Weight at 8 months =60 pounds
percent change in the puppy's weight= change in weight / Old weight x 100
(60 pounds -16pounds ) / 16 x 100
44/16 x 100 = 275%
Emily has $100 extra to spend on supplies for her T-shirt-making business.
She wants to buy ink, i, which costs $5 a bottle, and new brushes, b, which are
$12 each. Which inequality below represents this scenario?
A. 12i + 5b < 100
B. 5i + 12b < 100
C. 5i + 12b > 100
D. 5i + 100 < 12b
Answer:
B. 5i + 12b < 100
Step-by-step explanation:
I used process of elimination on to figure this one out.
I first eliminated A because I knew the i should be next to the 5. I know this because i (ink) costs 5 dollars each.
I next eliminated D because this equation is looking to find the sum of the ink and the new brushes, not the ink plus the total cost equaling the brushes.
Finally, I eliminated C because Emily only has $100, so the cost of the ink (i) and the brushes (b) must NOT excede 100 dollars. From this, I can see that C states that the sum exceeds Emily’s $100 budget
This leaves us with B as the final answer

solve for A
Answer:
a = 4[tex]\sqrt{5}[/tex]
Step-by-step explanation:
pythagorean theorem:
a² + 8² = 12²
a² + 64 = 144
a² = 80
a = [tex]\sqrt{80}[/tex]
a = [tex]\sqrt{4}[/tex]·[tex]\sqrt{4}[/tex]·[tex]\sqrt{5}[/tex] which simplifies to be 4[tex]\sqrt{5}[/tex]
