Hay 50 estudiantes en un mariachi estudiantil. Dos quintas partes tocan el violín. Una quinta parte de los violinistas también toca la guitarra. ¿Cuántos violinistas NO tocan la guitarra?
Answer:
La cantidad de violinistas que NO tocan la guitarra es 16.
Step-by-step explanation:
Hay 50 estudiantes en un mariachi estudiantil. Siendo dos quintos [tex]\frac{2}{5}[/tex] la cantidad de estudiantes que tocan el violín, entonces la cantidad de estudiantes que tocarán ese instrumento será calculado como la multiplicación entre dos quintos y la cantidad de estudiantes:
[tex]\frac{2}{5} *50= 20[/tex]
Por otro lado, saber que una quinta parte ([tex]\frac{1}{5}[/tex]) de los violinistas también toca la guitarra. Entonces la cantidad de estudiantes que tocarán la guitarra y el violín será calculado como la multiplicación entre un quinto y la cantidad de estudiantes que tocan el violín (20 estudiantes):
[tex]\frac{1}{5} *20= 4[/tex]
El resto de los violinistas NO tocan la guitarra. Se calcula como la diferencia (resta) entre el número total de violinistas y aquellos estudiantes que también tocan la guitarra:
20 - 4= 16
La cantidad de violinistas que NO tocan la guitarra es 16.

The total length of two ships is 2341 feet. The difference in their lengths is 13 feet.
a. Find the length of each ship.
b. If a football field has a length of 100 yards, determine the length of the longer ship in terms of football fields.
Answer:
The smaller ship is 1,164 ft
The larger ship is 1,177 ft
The larger ship is 3.923 football fields
Step-by-step explanation:
A. Find the length of each ship
x + x + 13 = 2,341 ft
2x + 13 = 2,341 ft
2x = 2,328 ft
x = 2,328/2
x = 1,164 ft ( This is the length of the smaller ship)
1,164 + 13 = 1,177 ft (length of the larger ship)
B)If a football field has a length of 100 yards, determine the length of the longer ship in terms of football fields.
1,177/3ft= 392.3 yards
392.3 yards /100 yards = 3.923 football fields

Answer:
Step-by-step explanation:
amount of discount = $10
percentage discount = $10/$39.99 ≅ 0.25 = 25%
amount of sales tax = $1.95
sales tax rate = $1.95/$29.99 ≅ 0.065 = 6.5%
cost of jeans × 1.60 = $39.99
cost of jeans = $39.99/1.60 ≅ $24.99
discounted selling price = $29.99
markup = $29.99/$24.99 ≅ 1.20 = 20%

Answer:
7√2
Step-by-step explanation:
The triangle is a "special triangle", an isosceles right triangle. The side lengths of this triangle have the ratios 1 : 1 : √2. Multiplying these ratio values by 7, the length of the leg, you find ...
c = 7×√2
c = 7√2
_____
If you like, you can go through the Pythagorean theorem and/or trigonometry to find the same thing.
7/c = sin(45°)
c = 7/sin(45°) = 7/(1/√2) = 7√2
Or ...
c² = 7² + 7² = 98 . . . . using the Pythagorean theorem*
c = √98 = 7√2
__
* This requires you recognize the triangle is isosceles, so the other leg is also 7. Of course, you know that as soon as you see a 45° acute angle in a right triangle.

Answer:
D (last one), [tex]x^2+y^2=45[/tex]
Step-by-step explanation:
We need to find the distance between (0,0) and (-3,6). Using the distance formula we get:
[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]
[tex]d=\sqrt{\left(-3-0\right)^2+\left(6-0\right)^2}[/tex]
[tex]d=3\sqrt{5}[/tex]
Since equation of circle is: [tex]x^2+y^2=r^2[/tex] we have to square the distance we just found, which gives us 45.
Answer:
x^2 + y^2 = 45
Step-by-step explanation:
(x − a ) ^2 + ( y − b ) ^2 =r^2
= (-3-0)^(2)+(6-0)^(2)
=45
Amanda bought tickets for a concert for $218. Jamie bought tickets to the same concert but paid 14% less than Amanda. What were the price of Jamie's tickets?
Answer:
Jamie's tickets = $187.48
Step-by-step explanation:
The amount for which Amanda bought tickets = $218
Jamie bought tickets to the same concert but paid 14% less than Amanda.
Jamie's tickets = [tex]218-14\%\ of\ 218[/tex]
We can solve it as follows :
[tex]218-14\%\ of\ 218=218-\dfrac{14}{100}\times 218\\\\=218-30.52\\\\=\$187.48[/tex]
So, the price of Jamie's tickets is $187.48.
26 sit ups in 2 minutes . find the unit rate and how many in 5 minutes
Answer:
Unit rate: 13 sit ups per minute
65 sit ups can be done in 5 minutes
Step-by-step explanation:
Find the unit rate by dividing 26 by 2
26/2
= 13
This means 13 sit ups can be done in 1 minute.
To find how many can be done in 5 minutes, multiply 13 by 5.
13(5)
= 65
So, the unit rate is 13 sit ups per minute, and 65 sit ups can be done in 5 minutes.
The graph of 2x+y=8 is shown on the graph below. Graph the equation y=13x−6 on the same coordinate plane below. Plot the point that represents the solution to the system consisting of the two equations. HELP PLSS
the exact solution for the system of equations is the point (0.93, 6.13)
How to find the solution for a system of equations by graphing?When we have a system of two (or more) equations, to solve it graphically we just need to graph both equations in the same coordinate axis and then find where (if they do) the graphs intersect.
Each intersection will give one solution for the system.
In this case we have the system of equations:
2x + y = 8
y = 13x - 6
And the graph of these two can be seen in the image below.
Using that graphing tool we can see that the exact solution for the system of equations is the point (0.93, 6.13)

5x - 2y = -10
3x + 6y = 66
Answer:
y = 5/2x + 5
y = -1/2x + 11
Step-by-step explanation:
5x -2y = -10
-2y = - 5x -10
y = 5/2x + 5
3x + 6y = 66
6y = -3x + 66
y = -1/2x + 11
In 2011, a professional climber scaled the outside of the Burj Khalifa, making it all the way to 828 meters (the highest point on which a person can stand) in 6 hours.
Answer:
276 meters in the first 2 hours
Step-by-step explanation:
Given that,
Professional climbers climb 828 meters in 6 hours.
Let us assume we need to find how far did they climb in the first 2 hours.
6 hours = 828 m
⇒ 1 hour = 138 m
So, in 2 hours,
2 hours = 138 × 2 m
= 276 m
So, the climber climb 276 meters in the first 2 hours

Answer:
V = 1520 m^3
Step-by-step explanation:
Volume equals Area of the base * height.
V = length * width * height
V = l * w * h
V = 19 * 5 * 16

Step-by-step explanation:
Tell whether the equation has one, zero, or infinitely many solutions.9(x − 3) + 15 = 9x − 11.
Answer:
Zero solutions; there are no variables and thus there are no solutions
Step-by-step explanation:
We start out with the equation 9 (x - 3) + 15 = 9x - 11
Which simplifies to 9x - 27 + 15 = 9x - 11
The 9x terms cancel each other out, and we're left with 15 - 27 = -11
And we end up with -12 = -11, which is not true.
This tells us that the equation has zero solutions, because no matter what value we substitute for x, the equation will not be true.
Answer:
No solution
Step-by-step explanation:
9(x-3)+15= 9x-11
9x-27+15=9x-11
-15 on both sides
9x-27=9x-26
add 26 on both sides
9x -1=9x
add 1 on both sides
9x=9x+1
divide 9 on both sides
x=x+1/9
No solution

Step-by-step explanation:
Open circle means "excluding that number". Since x>6, x cannot be 6 so we have an open circle at 6. x>6 also means x has to be greater than 6, so we have the arrow going to the right since 7 is greater than 6, 8 is greater than 6, and so on so forth.
