Answer:
AB = 5
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
=> 3² + 4² = AB²
=> AB = [tex]\sqrt{3^{2}+4^{2} }[/tex]

The box plot show the lengths of the songs on two digital music players in minutes .Which statement is best supported by the information in the box plots ?
Solution :
In the figure, the box plot represents the lengths of the songs of the two digital music players that is in minutes.
From the figure, we can see that for the music player Y, the interquartile range of the data is small.
And the interquartile range of data is more for the music player X.
So, we can conclude that the interquartile range of data is greater for Music player X than the interquartile range data of music player Y.
Brody deposited $500 into a savings account that earns 2.1% simple interest. What is the total amount in his account after 7 years?
Answer:
73.5
Step-by-step explanation:
Part/whole=percent/100
?/500=2.1%/100
500 divided by 100 is 5, so 2.1% times 5 is 10.5, which is the amount of interest made per year.
So, 10.5 times 7 is 73.5

The temperature was 48°F and dropped 15° in two hours.
What was the temperature after the change?
Answer:
33 degrees Fahrenheit.
Step-by-step explanation:
If the temperature was 48 degrees, and it dropped 15, that means the initial temperature was subtracted by 15.
48 - 15 = 33.
Answer:
33°F
Step-by-step explanation:
The initial temperature was 48°F. Then, it dropped by 15°.
I am assuming that both values are given in the same unit.
48 - 15 = 33
The temperature should be 33 degrees now.

La temperatura mínima en una ciudad el día lunes fue de –2 ºC y la máxima fue de 7 ºC. ¿Cuál fue la variación de temperatura en el día?
Answer:
La variación de temperatura en el día es 9°C.
Step-by-step explanation:
Cuando tenemos dos valores, uno máximo M y uno mínimo m, la variación entre esos valores es la diferencia (la resta) entre el valor máximo M y el valor mínimo m
variación = M - m
En este caso sabemos que la temperatura mínima es -2°C
La temperatura máxima es 7°C
La variación sera entonces:
Variación = 7°C - (-2°C)
Recordar la regla de los signos:
(-)*(-) = (+)
Entonces:
Variación = 7°C - (-2°C) = 7°C + 2°C = 9°C
La variación de temperatura en el día es 9°C.

A house has increased in value by 35% since it was purchased. If the current value is 648,000, what was the value when it was purchased?
Answer:
Purchase rate of the house is $480000.
Step-by-step explanation:
Let the purchase rate of the house = $p
Current value of the house = $648000
If the current rate of the house has increased by 35% of the purchase rate,
Current rate = Purchase rate + 35% of the purchase rate
648000 = p + (35% of p)
648000 = p + [tex]p\times \frac{35}{100}[/tex]
648000 = p + 0.35p
648000 = (1.35)p
p = [tex]\frac{648000}{1.35}[/tex]
p = $480000
Therefore, purchase rate of the house is $480000.
Should you use Sine, Cosine, Tangent to solve the following problem
Answer:
tangent
Step-by-step explanation:
SOH( sin = opposite/hypotenuse)
CAH(cosine = adjacent/hypotenuse)
TOA(tan = opposite/adjacent)
you are trying to find x and the numbers given to you are opposite of x and adjacent to x. that means you need to use toa
We will use Tangent of the angle.
What is Tangent of the angle?In trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
Given that, a right triangle, with perpendicular = x and an acute angle = 28° and base = 14
Since, we know that, tan α = opposite side / adjacent side
In other two trigonometric ratios, we need the length of hypotenuse, which is not given.
Hence, We will use the Tangent of the angle.

Un arquitecto ha pagado en un corralón un total de $ 130 por 20 Ladrillos, 5 kg de Arena y 10 kg de Cemento. Calcular el precio de cada articulo, sabiendo que 1 kg de Cemento cuesta el triple que 1 Ladrillo y que 1 kg de Arena cuesta igual que 4 kg de Cemento más 4 Ladrillos. Siendo: número de ladrillos y: kg de arena kg de cemento
Answer:
1 ladrillo cuesta 1 dólar. 1 brick costs 1 dollars.
1 kg de cemento cuesta 3 dólares: 1 kg cement costs 3 dollars
1 kg de arena cuesta $ 16: 1 kg sand costs $ 16
Step-by-step explanation:
Spanish
Deje que los ladrillos, la arena y el cemento se denoten por b, sy c. Luego, de acuerdo con la condición dada
20b + 5s + 10c = $ 130 --- ecuación 1
1c = 3b ------ ecuación 2
1s = 4c + 4b ------ ecuación 3
Poniendo la ecuación 2 en la ecuación 3
1s = 4 (3b) + 4b
1s = 16b ---------- ecuación 4
20b + 5s + 10 (3b) = $ 130
50b + 5s = 130 --- ecuación 5
Poniendo la ecuación 4 en la ecuación 5
50 b + 5 (16b) = 130
50 b + 80b = 130
130 b = 130
b = 130/130 = $ 1 ------- ecuación a
1 ladrillo cuesta 1 dólar.
Poner el valor de costo de 1 ladrillo en estas ecuaciones
1c = 3b ------ ecuación 2
1s = 4c + 4b ------ ecuación 3
1c = 3 (1) = $ 3 -------- ecuación b
1 kg de cemento cuesta 3 dólares
1s = 4c + 4b
1 s = 4 (3) + 4 (1)
1 s = 12 + 4
1s = $ 16 ------ ecuación c
1 kg de arena cuesta $ 16
Poner valores de la ecuación a, b, c en la ecuación 1
20b + 5s + 10c = $ 130
20 (1) + 5 (16) + 10 (3) = 130
20 + 80 + 30 = 130
130 = 130 ------------ por lo tanto probado
English
Let the bricks , sand and cement be denoted by b, s and c. Then according to the given condition
20b+ 5s+ 10c= $130--- equation 1
1c= 3b------ equation 2
1s= 4c+4b------ equation 3
Putting equation 2 in equation 3
1s= 4(3b) + 4b
1s= 16b---------- equation 4
20b+ 5s+ 10(3b)= $130
50b + 5s= 130--- equation 5
Putting equation 4 in equation 5
50 b + 5 (16b) = 130
50 b+ 80b= 130
130 b= 130
b= 130/130= $1------- equation a
1 brick costs 1 dollars.
Putting the cost value of 1 brick in these equations
1c= 3b------ equation 2

1c= 3(1)= $3-------- equation b
1 kg cement costs 3 dollars
1s= 4c+4b
1s= 4(3) + 4(1)
1s= 12+4
1s= $16 ------ equation c
1 kg sand costs $ 16
Putting values from equation a, b, c in equation 1
20b+ 5s+ 10c= $130
20 (1) + 5 (16) + 10 (3)= 130
20 + 80 + 30 = 130

Which equation matches the function shown in the graph?
A. y=2sin(1/2x)+1
B. y=3sin(2x)
C. y=2sin(2x)+1
D. y=3sin(1/2x)
Answer:
the answer is A. y=2sin(1/2x)+1
Step-by-step explanation:
I input all four functions on desmos (a graphing calculator), and saw that A. y=2sin(1/2x)+1 was similar to the function shown in the graph
The function that matches the graph is y= 2 sin(1/2x) +1.
What is graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given:
let y = A sin ([tex]\omega[/tex]x + Ф)+ k
T= 4π, w= 2π/T = 1/2
Now, midline= 1/2( max + min)
=1/2(3-1)= 2/2
k=1
and, A= 3-1 = 2
So, y= 2 sin(1/2x + Ф) +1
as, Ф=0
So, y= 2 sin(1/2x) +1

-1/2(10 + 1/4)
10+1/4 = 41/4
Since the denominator is 4, you multiply 10 by 4 to make it equivalent since 10 is a whole number and 1/4 is a fraction
-1/2(10.25)= -41/8 or 5.125

Answer:
[tex]2x^2+x+7y[/tex]
Step-by-step explanation:
We are given the equation [tex]2(x^2+3y)+x+y[/tex] and are asked to simplify it.
To do so, we need to first get rid of the parenthesis, since x² and 3y aren't like terms, it isn't solvable unless we try another way, which is the distributive property.
2 is next to the parenthesis, in the distributive property, we would multiply the number outside of the parenthesis with all the numbers inside the parenthesis. Therefore :
[tex](2*x^2) + (2*3y) + x +y[/tex]
[tex]2x^2 +6y+x+y[/tex]
Now that we have like terms, we can add them together :
[tex]2x^2 + 6y+x+y[/tex]
[tex]2x^2 + x+7y[/tex]

Hello! Your answer would be, 2[tex]x^{2}[/tex] + [tex]x[/tex] [tex]7y[/tex]
