Answer:
36 trees
Step-by-step explanation:
We are told that It takes four workers six hours and 45 minutes to plant 24 trees. Also that the time it takes to plant trees varies directly with the number of trees and inversely with the number of workers.
Thus,
t ∝ x/n
Where;
x is number of trees
n is number of workers
Now, opening the proportion symbol, we have;
t = kx/n
Where k is the constant of proportionality.
t = 6 hours 45 minutes = 6¾ hours = 6.75 hours
Plugging in the relevant values, we have;
6.75 = 24k/4
k = 4 × 6.75/24
k = 1.125
Now, we want to know how many trees could 9 workers plant in four and a half hours (4.5 hours)
Applying the same as above and Plugging in k = 1.125, we have;
4.5 = 1.125x/9
x = 9 × 4.5/1.125
x = 36 trees

Use the information to answer the following questions. The angle measures of a triangle are shown. Angle A: (5x – 5) degrees Angle B: (3x + 3) degrees Angle C: (5x) degrees What expression can be written to represent the sum of the angle measures?
Answer:
5x-5+3x+3+5x=180
Step-by-step explanation:
As it is a triangle, sum of all angles is 180.
5x-5+3x+3+5x=180
13x=182, x=14
The expression that represents the measure sum of the angle is
(5x – 5)° + (3x + 3)° + (5x)° = 180°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We also know that sum of all the interior angles of a triangle is 180°.
The given statement can be written as,
∠A + ∠B + ∠C = 180°.
(5x – 5)° + (3x + 3)° + (5x)° = 180°.
13x - 2° = 180°.
13x = 180° + 2°.
13x = 182°.
x = 14°.
We can also find the measure of each angle now by substituting the value of x in ∠A, ∠B, and ∠C.

Answer: x = √(((-F - 4)^2)/16 - 1/2) + (F + 4)/4 or x = (F + 4)/4 - √(((-F - 4)^2)/16 - 1/2)
Step-by-step explanation:
Solve for x:
F x = 2 x^2 - 4 x + 1
Subtract 2 x^2 - 4 x + 1 from both sides:
-2 x^2 + F x + 4 x - 1 = 0
Collect in terms of x:
-1 + x (F + 4) - 2 x^2 = 0
Divide both sides by -2:
1/2 + 1/2 x (-F - 4) + x^2 = 0
Subtract 1/2 from both sides:
1/2 x (-F - 4) + x^2 = -1/2
Add 1/16 (-F - 4)^2 to both sides:
1/16 (-F - 4)^2 + 1/2 x (-F - 4) + x^2 = 1/16 (-F - 4)^2 - 1/2
Write the left hand side as a square:
(1/4 (-F - 4) + x)^2 = 1/16 (-F - 4)^2 - 1/2
Take the square root of both sides:
1/4 (-F - 4) + x = √(1/16 (-F - 4)^2 - 1/2) or 1/4 (-F - 4) + x = -√(1/16 (-F - 4)^2 - 1/2)
Subtract 1/4 (-F - 4) from both sides:
x = √(((-F - 4)^2)/16 - 1/2) + (F + 4)/4 or 1/4 (-F - 4) + x = -√(1/16 (-F - 4)^2 - 1/2)
Subtract 1/4 (-F - 4) from both sides:
Answer: x = √(((-F - 4)^2)/16 - 1/2) + (F + 4)/4 or x = (F + 4)/4 - √(((-F - 4)^2)/16 - 1/2)

Step-by-step explanation:
top is correct
We want to know when a point is a solution to a system of inequalities. We will see that the correct option is "lies in the shaded regions of both the top and bottom inequalities."
Solution of an inequality:A point is a solution to a inequality if and only if it belongs to the shaded region of the graph.
Solution of a system of inequalities:
A point is a solution to a system of inequalities if and only if it is a solution of each independent inequality that conforms the system.
Then, it must belong to all the shaded regions that represent the solution set of the inequalities at the same time, this means that it must belong to the intersection of the shaded regions.
From this, the correct option is:
"lies in the shaded regions of both the top and bottom inequalities."

segment?
Write the coordinates as decimals or integers.
M =
Answer:
The midpoint (x,y)=(6,9)
Step-by-step explanation:
We need to find midpoints(x,y) of the line segment having endpoints S(8, 8) and T(4, 10)
The formula to find midpoint is:
[tex]Midpoint(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\[/tex]
We are given: [tex]x_1=8, y_1=8, x_2=4 , y_2=10[/tex]
Putting values and finding midpoint
[tex]Midpoint(x,y)=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint(x,y)=(\frac{8+4}{2},\frac{8+10}{2})\\Midpoint(x,y)=(\frac{12}{2},\frac{18}{2})\\Midpoint(x,y)=(6,9)[/tex]
So, the midpoint (x,y)=(6,9)
Read the excerpt from The Call of the Wild.
Then an old wolf, gaunt and battle-scarred, came forward. Buck writhed his lips into the preliminary of a snarl, but sniffed noses with him, Whereupon the old wolf sat down, pointed nose at the moon, and broke out the long wolf howl. The others sat down and howled. And now the call came to Buck in unmistakable accents. He, too, sat down and howled. This over, he came out of his angle and the pack crowded around him, sniffing in half-friendly, half-savage manner. The leaders lifted the yelp of the pack and sprang away into the woods. The wolves swung in behind, yelping in chorus. And Buck ran with them, side by side with the wild brother, yelping as he ran.
Which theme does this passage illustrate?
A good leader is strong and intelligent and treats his followers well.
Only the strong survive in the wilderness.
The only way to learn something is to try it.
The desire to fight for power is an instinct.
Answer:
The passage is centered on the theme of belonging in a certain pack or group. Buck may be a bit different from the others but as Buck tried to be like them and did what they usually do, it gathered the trust of the pack especially the leaders. To belong in a group, one should gain their trust.

Explain why sine of an angle greater than 180° and less than 360° is negative.
9514 1404 393
Explanation:
The sine of an angle in standard position is the y-coordinate of the intersection of its terminal ray with the unit circle. When the angle is in the range 180° < θ < 360°, that point of intersection is in quadrant III or IV, where y-coordinates are negative.

That is where the sine curve is below the x-axis.
Yesterday you walked 2 7/10 miles on your treadmill. Today you walked 1 6/10 miles. How far did you walk in these two days? Also I need an answer that looks like this 3 4/5
Answer:
The answer is 4 3/10
Step-by-step explanation:
If you first break this question up into two steps, you first must add the whole numbers and then the fractions, like this:
2 7/10 1 6/10
First, add the whole numbers [Bold]
2 + 1
That equals the whole number 3
2 7/10 1 6/10
Next you add the fractions [Underlined]
7/10 + 6/10
this equals 13/10
Since this fraction is higher than 10/10, it equals a whole number too. This fraction, 13/10, will be simplified to 1 whole and 3/10. After simplifying this number you add the whole numbers once again resulting in 3 + 1, giving you 4. after finding this out you add your fractions back in, creating the answer of 4 3/10.
Hope this helps you out!
