Answer:
0.103 acres
Step-by-step explanation:
This question tests on the concept of Conversion.
Given from the question, we know that:
107 pounds of seed = 11 acre field
To find the acres of field we can plant per pound of seed, we simply divide both sides of the equation by 107.
(107 ÷ 107) pounds of seed = (11 ÷ 107) acres of fiels
1 pound of seed = 0.103 acres of field (Rounded off to 3 significant figures)

5. Below is a model of the infield of a baseballstadium. How long is each side of the infield?oth a perfectquare rootnumbers?A= 81 in.?
We have that the area of the infield is 81 in2.
This area is a square, which means it has equal sides, and its area is:
[tex]\text{Area}=side^2[/tex]If the area of the square is 81 in2, we have that:
[tex]\begin{gathered} \text{side}^2=81 \\ \text{side}=\sqrt{81} \\ \text{side}=9\text{ in} \end{gathered}[/tex]So the side of the infield is 9 inches.

What is combination and permutation?
Combination and permutation are two alternative strategies in mathematics to divide up a collection of components into subsets. The subset's components can be listed in any order when combined. The components of the subset are listed in a permutation in a certain order.We are to find the number of different combinations of classes does Sylvia have to choose from.
We will be using the following formula for number of combinations of n elements taken r (r is less than or equal to n) at a time:
nCr = n!/r!( n - r )!
Since Sylvia needs to sign up for exactly one class in each subject, so the total number of different combinations from which she has to choose will be
⁴C₁ * ²C₁ * ³C₁ * ⁵C₁
= 4!/1!( 4 - 1 )! × 2!/1! ( 2 - 1 )! × 3!/1! ( 3 -1)! × 5!/1! ( 5 - 1 )!
= 4 × 2 × 3 × 5
= 120
Thus, the total number of different combinations is 120.

a forest trail is 607 feet long. a person biked from one end to the other and back again 6 times in the past 5 weeks. how far the person bike over the past 5 weeks
The distance that the person bike over the past 5 weeks is 7284 feet.
How to illustrate the expression?Distance is the sum of an object's movements, regardless of direction. Regardless of an object's starting or ending position, distance can be defined as the amount of ground it has covered. Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively.
From the information, the forest trail is 607 feet long and a person biked from one end to the other and back again 6 times in the past 5 weeks.
Therefore, the distance that the person covered will be:
= 2 × 6 × 607
= 7284 feet.
The distance is 7284 feet.

Kali just started a new sales floor job to save for college. She earns $15.75 per hour plus a flat fee of $50 per week. She wants to earn between $200 and $400 per week. The following inequality represents her earning potential: 200 ≤ 15.75x + 50 ≤ 400 Solve the inequality.
The solution set of the given inequality is:
9.52 ≤ x ≤ 22.22
Or [9.52, 22.22] if we write this as an interval.
How to solve the inequality?Here we have the inequality:
200 ≤ 15.75x + 50 ≤ 400
Which represents Kali's earning potential.
To solve the inequality we need to isolate the variable in the middle, if we subtract 50 in the 3 sides we get:
200 - 50 ≤ 15.75x + 50 - 50 ≤ 400 - 50
150 ≤ 15.75x ≤ 350
Now we need to divide both all by 15.75, so we get:
150/15.75 ≤ 15.75x/15.75 ≤ 350/15.75
9.52 ≤ x ≤ 22.22
This is the solution of the inequality, the solution set written as an interval will be [9.52, 22.22]

Between 10 pm and 7:45 am the water level in a swimming pool decreased by 3/16 inches
The rate of change of the level of the swimming pool is -0.019 inches per hour.
How to get the rate of change in the level of the swimming pool?
The rate of change will be given by the quotient between the change in the level of the water (-3/16 inches) and the time in which that change happens.
We know that the change happens between 10 pm and 7:45pm, so the number of hours is:
2 hours + 7 hours + 45 min
Where:
1 hour = 60 min
45 min = 45/60 hours = 0.75 hour
Then the total time is:

What is angle sum property of triangle?The sum of the interior angles in a triangle is supplementary. In other words, the sum of the measure of the interior angles of a triangle equals 180°. So, the formula of the triangle sum theorem can be written as, for a triangle ABC, we have ∠A + ∠B + ∠C = 180°.
In ΔOPQ,
∠O = (2x- 5)°
∠P = (3x-8)°
∠Q= (10x- 17)°
Thus by angle sum property of triangle we know:
∠O+ ∠P + ∠Q = 180
thus 2x - 5 + 3x - 8 + 10x - 17 = 180
15x - 30 = 180
= 15 x = 180 + 30
= 15 x = 210
= x= 210 / 15
= x = 14 .
Thus ∠O = (2x- 5)° = 2X 14 - 5 = 23 °
∠P = (3x-8)° = 3× 14 - 8 = 44°
∠Q= (10x- 17)° = 10 × 14 - 17 = 123°

If the vertical component of velocity for a projectile is 7.3 meters/second, find its hang time. a. 1.5 seconds b. 2.5 seconds c. 5.6 seconds d. 6.7 seconds e. 7.1 seconds
The hang time is calculated to be a. 1.5 seconds if the vertical component of velocity for the projectile is 7.3 meters/second.
The formula for the height of the projectile can be used to calculate the hang time as follows;
h = ut - 0.5at²
here;
h is the height of the projectile
u is the velocity = 7.3 m/s
a is the acceleration due to gravity
The standard value of acceleration due to gravity is equal to 9.81 m/s²
The height will be zero both the times when t=0 and when the journey has been completed
Now adding these values to the formula;
h = ut - 0.5at²
0 = 7.3t - 0.5(9.81)t²
Solving for t;
4.905t² = 7.3t
4.905t² / t = 7.3
4.905t = 7.3
t = 7.3 / 4.905
t = 1.49 ≈ 1.5

The coordinates of the point X are (1 + 2, 6 - 1.25) = (3,4.75).
The segments, PX and XQ, have lengths in a ratio of 1: 2.
What is meant by partition segment?A line segment is partitioned when it is divided into equal parts according to a specified ratio. The total number of partitions of the line segment must be equal to the sum of the two values in the ratio.
Suppose you have a line segment PQ on the coordinate plane, and you need to estimate the point on the segment 1/3 of the way from P to Q.
Where P exists at the origin and line segment is a horizontal one.
The length of the line exists 6 units and the point on the segment 1/3 of the way from P to Q would be 2 units away from P, 4 units away from Q and would be at (2, 0).
The segment exists not a horizontal or vertical line:
The components of the directed segment PQ exists (6, 3) and we require to estimate the point, say X on the segment 1/3 of the way from P to Q. Then, the components of the segment PX exists [tex]$\left\langle\left(\frac{1}{3}\right)(6),\left(\frac{1}{3}\right)(3)\right\rangle=\langle 2,1\rangle$[/tex].
Since the initial point of the segment exists at origin, the coordinates of the point X exists given by (0+2, 0+1) = (2, 1).
where neither P nor Q exists at the origin.
Use the end points of the segment PQ to estimate the components of the directed segment.
[tex]$\left\langle\left(x_2-x_1\right),\left(y_2-y_1\right)\right\rangle=\langle(7-1),(2-6)\rangle[/tex]
= (6,-4)
The components of the segment PX where X exists a point on the segment 1 / 3 of the way from P to Q are
[tex]$\left\langle\left(\frac{1}{3}\right)(6),\left(\frac{1}{3}\right)(-4)\right\rangle=(2,-1.25)$$[/tex]
To estimate the coordinates of the point X add the components of the segment PX to the coordinates of the initial point P.
Therefore, the coordinates of the point X exists (1+2,6-1.25) = (3, 4.75).
The segments, PX and XQ, have lengths in a ratio of 1: 2.
