Step-by-step explanation:
2/3 of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 15 red boats, how many boats are in the marina?
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.

WX=19
YW^2=19^2+31^2
YW^2=361+961
YW^2=1322
YW=36.36

ZX=18.18
VX=YW
VX=36.36
The measures of the rectangle are
a) The measure of VW = 31
b) The measure of WX = 19
c) The measure of YW = 36.36
d) The measure of ZX = 18.18
e) The measure of VZ = 18.18
What is the diagonal of a rectangle?The diagonal of a rectangle is calculated by the formula
From the Pythagoras Theorem , The hypotenuse² = base² + height² , and
Diagonal of a Rectangle = √ ( Length )² + ( Width )²
Given data ,
Let the rectangle be represented as VWXY
Now , the diagonals of the rectangle are VX and WY
Substituting the values in the equation , we get
The measure of VY = 19
The measure of XY = 31
Now , for a rectangle the opposite sides are congruent
So , the measure of VY = measure of WX
And , the measure of XY = measure of VW
On simplifying the equation , we get
The measure of WX = 19
The measure of VW = 31
And , the diagonal of the rectangle = √ ( Length )² + ( Width )²
Substituting the values in the equation , we get
The diagonal of the rectangle YW = √ ( 31 )² + ( 19 )²
The diagonal of the rectangle YW = √ ( 961 + 361 )
The diagonal of the rectangle YW = 36.359 ≈ 36.36
And , the measure of VX = measure of YW = 36.36
Now , the measure of ZX = measure of VZ = measure of VX / 2
So , the measure of ZX and VZ = 36.36 / 2 = 18.18
Hence , the diagonal of the rectangles is 36.36

Suppose that the height H of a Ferris wheel can be modeled by the function n H(t)= -16cos(t/45)+24, where t is the time in seconds. What is the maximum height of a cabin? Use 3.14 for π
Answer:
40 feet.
Step-by-step explanation:
The height of the Ferris Wheel is modeled by:
[tex]\displaystyle H(t)=-16\cos\Big(\frac{t}{45}\Big)+24[/tex]
Where H(t) is the height (in feet (assuming)) and t is the time in seconds.
Remember that the value of cosine, regardless of the input, will always be between -1 and 1. That is:
[tex]-1\leq \cos(t)\leq 1[/tex]
So, we can use the two maximums. Testing -1 and 1, we get:
[tex]H(t)=-16(1)+24=8[/tex]
And:
[tex]H(t)=-16(-1)+24=40[/tex]
Therefore, the maximum height of a cabin of the Ferris Wheel will be 40 feet in the air.
Notes:
And the minimum height will be 8 feet.
We are not asked to find t. To do so, however, set H(t) = 40 and find the general solution for t.

Answer:
a) A = 36π in² ≈ 113.09 in²
b) $0.98 per slice
c) $0.09 per square inch
Step-by-step explanation:
a) area = πr²
r= diameter/2 = 12/2 = 6
A = π(6)²
A = 36π in² ≈ 113.09 in²
b) s = price per slice
s = 9.75 ÷ 10
s = $0.975 ≈ $0.98
c) price per square inch = price ÷ area
= 9.75 ÷ 113.09
= $0.086 ≈ $0.09 per square inch

The listed price of the video game was $34, but the price with tax came to $37.40. Find the percent sales tax.
Answer:
10%
Step-by-step explanation:
we want to find what % of 34 is 37.40
so, we will use the following equation:
[tex]\frac{part}{whole} = \frac{percent}{100}[/tex]
for this scenario:
part = 37.40
whole = 34
percent = x
now plug in:
[tex]\frac{37.40}{34} = \frac{x}{100}[/tex] cross multiply
34x = (37.40)(100)
34x = 3740 divide both sides by 34
x = 110%
now we know that with tax, we paid 110% of the video game's price
110 - 100 = 10%
so the percent sales tax is 10%
just to check...
34 • 1.10 = $37.40
or
34 • .10 = 3.40
34 + 3.40 = 37.40
Sara receives a 9% commission on every car she sells. The car dealership paid $20,000 for a car from an auction. The next day they sold the car for 20% more than they paid. How much commission did Sara earn on the selling price of the car?
Hey there! Your answer to this problem is 2160..
Explanantion:
Since every car Sara sells, she gets 9% of the commission, this means that at the last few step, we would have to give 9% of the total cost to Sara.
If 100% is 20,000, then 50% would be 10,000. But we have to find the cost of 20%. So what we would actually be doing is multiplying 20 with 0.01. 20x0.01 is 0.2 or 0.20.
Then you add the 4,000 to the 20,000 because it states, “the next day, they sold the car 20% more than they paid. This means that you’ll have to add it. 20,000 plus 4000 would be 24,000. So 24,000 would be the cost of the car they sold.
However they didn’t wanna know the cost of the car, they wanted to know how much Sara would get. So you would have to take 9% of the cost of the cost which would be 2,160.
Final result: $2,160
On a Saturday, Saul can cut 4 lawns in 6 hours. If Mitch can mow lawns at the same rate, how long will it take him to mow 9 lawns?
12 hours
12 3/4 hours
6 hours
13 1/2 hours
Answer:
13 1/2 is your answer.
Step-by-step explanation:
With the same ratio the time taken Mitch to mow 9 lawns will be 13 + 1/2 thus option (D) is correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
Saul can cut 4 lawns in 6 hours.
The ratio of hours to lawns will be as,
6/4
Suppose the time taken to mow 9 lawns to Mitch is x hours.
The ratio of hours to lawns will be as
x/9
Since the rate is the same thus ratio must be the same.
x/9 = 6/4
x = 6/4 x 9
x = 13.5 = 13 + 1/2
Hence"With the same ratio, the time taken Mitch to mow 9 lawns will be 13 + 1/2".

Un embalse estaba lleno a finales del mes de mayo. En el mes de junio se consumieron 3/10 de sus reservas y a finales de julio solo quedaba la mitad. ¿Qué fracción del embalse se consumió durante el mes de julio?
The English translation of the question is
A reservoir was full at the end of May. In the month of June 3/10 of its reserves were consumed and at the end of July only half remained. What fraction of the reservoir was consumed during the month of July?
Answer:
1/5 of the Reservoir will be consumed in the month of July.
Step-by-step explanation:
We are given
Full reservoir at the end of month May. In the month of June 3/10 of the reservoir was consumed.
Amount present in the Reservoir at the end of the month June will be = 1 -3/10
= 7/10
Now this 7/10 of the Reservoir will be used for the next month which is July
It is given that at the end of July only 1/2 of the Reservoir is remained that means the amount that was left at the end of the Month June will be used for the month July. So the amount consumed in the month of July will be
Amount consumed = 7/10 - 1/2
= 2/10 = 1/5
Therefore 1/5 of the reservoir will be consumed in the month of July.

The corresponding angles of the triangles are equal. Then the triangles ΔFGH and ΔMLN are similar triangles.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
In triangle ΔLMN, the measure of the third angle is calculated as,
∠N + ∠M + ∠L = 180°
∠N + 51° + 36° = 180°
∠N = 93°
In triangle ΔFGH, the measure of the third angle is calculated as,
∠H + ∠F + ∠G = 180°
∠H + 51° + 36° = 180°
∠H = 93°
In triangles ΔFGH and ΔMLN, the corresponding angles are equal. Then the triangles ΔFGH and ΔMLN are similar triangles.
