Answer: The total boats in the marina are 105.
Step-by-step explanation:
Let the total number of boats in the marina = x
Given : Number of white boats in the marina = [tex]\frac{2}{3}x[/tex]
Number of blue boats in the marina = [tex]\frac{4}{7}\times (x-\frac{2x}{3})=\frac{4}{7}\times \frac{x}{3}=\frac{4x}{21}[/tex]
Number of red boats in the marina = [tex]x-\frac{2x}{3}-\frac{4x}{21}=\frac{3x}{21}[/tex]
Given : Number of red boats in the marina = 15
[tex]\frac{3}{21}\times x=15[/tex]
[tex]x=105[/tex]
Thus total boats in the marina are 105.
By working with fractions and proportions, we will see that there are 105 boats in the marina.
Working with the given information:
Let's say that there are N boats in the marina, we know that:
2/3 of these are white, then the proportion of boats that are not white is:
1 - 2/3 = 3/3 - 2/3 = 1/3.
Of these, 4/7 are blue, then the proportion of red ones is:
1 - 4/7 = 7/7 - 4/7 = 3/7
The total proportion of red boats is:
(3/7)*(1/3) = 1/7
And we know that there are 15 red boats, this means that:
(1/7)*N = 15
Solving for N we get:
N = 7*15 = 105
So there are 105 boats in the marina.

Answer:
x = 105°
Step-by-step explanation:
First to get to know the last angle of the triangle:
[tex]55 + 50 + x = 180 \\ x = 75[/tex]
The last angle of the triangle is 75°
To get the opposite angle we take 180° (the full angle) minus 75° which results in 105°
. Xander needs to collect at least 120 cans for a food drive to earn community |
service credit. He has already collected 64 items. Write and solve an inequality to
represent the number of cans, C, that Xander must still collect.
Answer:
64 + c = 120
Step-by-step explanation:
120 - 64 = 56 t therefore c = 56
The inequality to represent the number of cans, c, that Xander must still collect is c ≥ 55.
Given the information in the question, the least number of cans that Xander can collet is 120. He can collect more than 120 cans. Thus, the inequality sign to be used is the greater than or equal to sign - ≥.
The number of cans Xander must still collect = 120 - 64 = 55
The inequality solution is c ≥ 55

Jada has a meal in the Bobby Salazar's restaurant. She adds up the prices listed on the menu for everything they ordered and gets a subtotal for $48. If the tax rate is 8.7% how much is her taxes. (round to the nearest cent) $41.76 $4.76 $4.18 $3.84 $3.99
Answer:
Tax= $4.176 = $4.18
Step-by-step explanation:
Giving the following information:
She adds up the prices listed on the menu for everything they ordered and gets a subtotal for $48.
Tax rate= 8.7% = 0.087
To calculate the Tax, we need to use the following formula:
Tax= total spend*tax rate
Tax= 48*0.087
Tax= $4.176 = $4.18

como se convierte una fracción a decimal
Answer:
Para convertir una fracción en un decimal, dividimos el numerador entre el denominador. Si tenemos un número mixto, el número natural se mantiene a la izquierda del punto decimal.
Answer:
Aqui esta la respuesta
Step-by-step explanation:
The line in a fraction that separates the numerator and denominator can be rewritten using the division symbol. So, to convert a fraction to a decimal, divide the numerator by the denominator. If required, you can use a calculator to do this. This will give us our answer as a decimal.
A fraction is made up of two parts: a numerator and a denominator. It is used to represent how many parts we have out of the total number of parts.We can use bar models to represent the conversion from fractions to decimals.La línea de una fracción que separa el numerador y el denominador se puede reescribir usando el símbolo de división. Entonces, para convertir una fracción en decimal, divide el numerador por el denominador. Si es necesario, puede usar una calculadora para hacer esto. Esto nos dará nuestra respuesta como decimal.
Una fracción se compone de dos partes: un numerador y un denominador. Se usa para representar cuántas partes tenemos del número total de partes.Podemos usar modelos de barras para representar la conversión de fracciones a decimales.Hope this helps

Answer:
sin2θ = - [tex]\frac{24}{25}[/tex]
Step-by-step explanation:
Given
cosθ = [tex]\frac{3}{5}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex] and in fourth quadrant
Then this is a 3- 4- 5 triangle with opposite side = 4
sinθ < 0 in fourth quadrant, then
sinθ = - [tex]\frac{opposite}{hypotenuse}[/tex] = - [tex]\frac{4}{5}[/tex]
Using the double angle identity for sine
sin2θ = 2sinθcosθ
= 2 × - [tex]\frac{4}{5}[/tex] × [tex]\frac{3}{5}[/tex] = - [tex]\frac{24}{25}[/tex]

Answer:
x = 10
angle top = 118°
angle bottom = 62°
Step-by-step explanation:
6x + 2 + 11x + 8 = 180
17x + 10 = 180
17x = 170
divide both sides by 17.
x = 10
plug in the 10 to each equation to get the number for the angle
6(10) + 2 = 62°
11(10) + 8 = 118°

A large hose can fill 7/8 of a water tank in one hour. A small hose
can fill 3/4 of a water tank in one hour. How much more of a water
tank can the large hose fill in one hour than the small hose?
Answer: 1/8
Step-by-step explanation:
From the question, we are informed that a large hose can fill 7/8 of a water tank in one hour while a small hose
can fill 3/4 of a water tank in one hour.
To get the solution to the question above, we have to find the difference between the amount if water filled by the large and the smaller hose. This will be:
= 7/8 - 3/4
= 7/8 - 6/8
= 1/8
What is the length of Ac? Round to the nearest tenth.
Given:
The figure of a right angle triangle.
To find:
The length of the line segment AC.
Solution:
In a right angle triangle,
[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]
In the given right triangle ABC,
[tex]\tan (A)=\dfrac{BC}{AC}[/tex]
[tex]\tan (55^\circ)=\dfrac{BC}{AC}[/tex]
[tex]\tan (55^\circ)=\dfrac{15}{AC}[/tex]
[tex]AC=\dfrac{15}{\tan (55^\circ)}[/tex]
On further simplification, we get
[tex]AC=\dfrac{15}{1.428148}[/tex]
[tex]AC=10.503113[/tex]
[tex]AC\approx 10.5[/tex]
The length of side AC is equal to 10.5 m .
Therefore, the correct option is A.

what is f(x)=2(3)^x?
Answer:
This is an exponential function
Step-by-step explanation:
f(x)=2(3)^x is one example of the exponential function. Since f(0) = 2(1) = 2, the y-intercept is (0, 2). The x-axis is the horizontal asymptote. The graph begins in Quadrant II, passes through (0, 2) and continues to increase, faster and faster, in Quadrant I. Next time, please be more specific about what you'd like to know.
