Answer:
240 cm^3
Step-by-step explanation:
Volume of a rectangular prism = base area x height
the base is a rectangle, thus base area = width x length = 4 x 5 = 20 cm^2
20cm^2 x 12 = 240 cm^3

How to solve the following question attached?
Answer: AB=21.88 mm, BC=51.54 mm
Step-by-step explanation:
Given
[tex]\angle A=67^{\circ}[/tex]
[tex]AC=56\ mm[/tex]
The other two sides can find out using trigonometry
[tex]\Rightarrow \sin 67^{\circ}=\dfrac{BC}{AC}\\\\\Rightarrow \sin 67^{\circ}=\dfrac{BC}{56}\\\\\Rightarrow BC=56\sin 67^{\circ}\\\Rightarrow BC=51.54\ mm[/tex]
Similarly, for AB
[tex]\Rightarrow \cos 67^{\circ}=\dfrac{AB}{AC}\\\\\Rightarrow \cos 67^{\circ}=\dfrac{AB}{56}\\\\\Rightarrow AB=56\cos 67^{\circ}\\\Rightarrow AB=21.88\ mm[/tex]
Angle C is given by
[tex]\angle C=90^{\circ}-67^{\circ}\\\angle C=23^{\circ}[/tex]

Find the 42nd term.
Answer:
134
Step-by-step explanation:
This sequence is arithmetic because it's going up by sane number, 3. Hence, it also linear for the same reason. The equation is y=3x+(0th term). The 0th term is the one before the 1st term, 11, which would be 8.
So the equation to finc any xth term is y=3x+8.
Example, first term is 3(1)+8=11.
Example, second term is 3(2)+8=14.
Example, third term is 3(3)+8=17.
The 42nd term is 3(42)+8=126+8=134.

trigonometry. please help
Answer:
C) 3/5
Step-by-step explanation:
Have you heard of this way to memorize the trig ratios?
SOH-CAH-TOA (Say it out loud so you remember it.)
It represents these ratios:
Sine = opposite side / hypotenuse
Cosine = adjacent side / hypotenuse
Tangent = opposite side / adjacent side
In this problem, cos C = adj / hyp = BC / AC = 24 / 40.
That simplifies to 3/5

En un hospital el 30 % de los pacientes que acuden de manera diaria presentan problemas cardíacos. Si un día acuden al hospital 70 pacientes, ¿Cuántos pacientes acudieron ese día con problemas cardíacos?
Answer:
21 pacientes tienen problemas cardíacos de los 70 pacientes diagnosticados
Step-by-step explanation:
Paciente con problema cardíaco del total de pacientes diagnosticados = 30%
Total de pacientes que van al hospital en un día = 70
El total de pacientes con problemas cardíacos entre los 70 pacientes diagnosticados es
30% de 70 = 30/100 * 70 = 21

1. A box has square ends. Its length is 13 cm longer than its width and the volume of the box is 60 cubic centimeters. What are the dimensions of the box?
Answer:
2 cm
Step-by-step explanation:
Given that
The length is 13 cm longer than its width
And, the volume of the box is 60cm^3
We need to find out the dimension of the box
Since the box has square ends
So,
the height is equivalent to the width
Let us assume the width be W so the height also be W
Now the length is W + 13
The volume is
W × W × (W + 13) = 60
After solving this W is 2 cm

Answer:
D) p³ + 2; when p = 3 the number of plants is 29.
Step-by-step explanation:
Illiana cubed (³) the number of original plants, p, in the garden. Then, she added 2 more plants. We will use n for the number of total plants.
So, the equation should be p³ + 2. Substitute our value for p into the equation and solve.
p³ + 2 = n
3³ + 2 = n
27 + 2 = n
29 = n
There are 29 total plants.
The answer, then, is the last option, p³ + 2; when p = 3 the number of plants is 29.
Good luck ^^
Al padre de Juan le faltan 2 años para tener el doble de la edad de su hijo. Hace 16 años el padre tenía el triple de la edad de Juan. Calcular la edad actual del padre y del hijo.
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.

Answer:
A: sqrt(11)
B: 4.2
C: sqrt(26)
Step-by-step explanation:
First, 4^2 = 16
That means that sqrt 11 is smaller than 4.2 (a value greater than 4). This is because sqrt16>sqrt11.
Sqrt(26) is greater than sqrt(25) = 5. That means that it's greater than 4.2.
Hence, the order given above.
