A basket contains only apples and oranges, and the ratio of apples to oranges is 9:7. If there are 128 pieces of fruit in he basket, how many are oranges?
Answers
Answer:
There are 56 oranges in the basket, since the ratio of apples to oranges is 9:7. To calculate this, you can use the proportion method. First, set up a proportion using the ratio of apples to oranges (9:7):
9/7 = x/128
Then, solve for x.
x = (9/7) * 128
x = 112
Answer:
72 and 56
Step-by-step explanation:
Ratio of apples in the basket = 9x
Ratio of oranges in the basket = 7x
Total fruits in the basket = 128
So, Apples + Oranges = Total fruit
9x + 7x = 128
16x = 128
x = 128 ÷ 16
x = 8
∴ So, number of apples = 9x --> 9*8 = 72 apples
number of oranges = 7x --> 7*8 = 56 oranges

Plz helppp: Identify the graph of the equation. What is the angle of rotation for the equation? 21x^2-8√3 xy+13y^2=225
A. ellipse, 75 degrees
B. hyperbola, -60 degrees
C. ellipse, -30 degrees
D. hyperbola, 90 degrees
Answers
Answer:
The correct option is C.
C) ellipse, -30°
Step-by-step explanation:
General form of equation for a conic section is:
(A)x² + (B)xy + (C)y² + (D)x + (E)y + F = 0
The equation of the conic section is given:
21x² - (8√3)xy + 13y² = 225
21x² - (8√3)xy + 13y² - 225 = 0
Which can be rewritten as:
(21)x² + (-8√3)xy + (13)y² + (0)x + (0)y + (-225) = 0
where
A = 21
B = -8√3
C = 13
D = 0
E = 0
F = -225
Consult the table below.
As A ≠ C and and AC > 0 , the equation represents an ellipse
The angle of rotation can be found by following equation:
cot(2θ) = (A - C)/B
cot(2θ) = (21 - 13)/(-8√3)
2θ = cot⁻¹(8/-8√3)
2θ = 120°
θ = 60° (from x-axis)
As the major axis of ellipse lies on y-axis, axis of rotation from y-axis is
θ = -30°

How did you decide where to place your line of best fit? Describe your reasoning.
Based on your data, describe the relationship between age and the number of U.S. states a person can name in 60 seconds.
Do you see any areas in your data or points that could be considered clusters or outliers? Explain your answer in complete sentences.
Trolls will be reported
Answers
Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.
So basically the units are counting up by 5.
The x axis is age in years and y axis is the number of US states named in 60 seconds.
Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.
(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

0.5% of w = 12. Only the first answer has the equation equal to 12, so the first part is

Now to solve it, we want to get W alone, we can do that by dividing 0.005 on both sides. Since right now it's being multiplied we must do the opposite
\(w = \frac{12}{0.005} = 2400\)

I hope you will understand the travels
The smallest number of crossings needed to get the party safely across a river is 5.
To get the group of 3 explorers and 3 Marind-Anim guides safely across the river while ensuring that the explorers are never outnumbered by the guides, follow the following strategy:
Firstly, two of the 3 explorers cross the river together. One explorer (say, A1) comes back, leaving the other explorer (say, A2) on the other side.Then, one of the guides (say, B1) crosses the river with A2. A2 stays on the other side, and B1 comes back.Then, the two guides (B2 and B3) that are left cross the river together. One of the guides (B2) comes back, leaving one guide (B3) on the other side.A1 crosses the river again with B3, and B3 stays on the other side.At last, A2 crosses the river again, along with A1 and the two guides on the other side.That's how all three explorers and three guides can cross the river safely, and at no point during the crossings were the explorers outnumbered by the guides.
Thus, 5 is the minimum number of crossings needed to get the party safely across a river.
