It takes 113 pounds of seed to completely plant a 12 -acre field. how many acres can be planted per pound of seed?

Answers

Answer 1

The answer is 0.10619469026.

It takes about 9lbs of seed to plant 1-acre, so to find the answer divide 12/113 and you get how many acres 1lb of seed could cover.

Hope this helps :-)

An angle measures 7pi/9 radians. What is the degree measure of the angle?

Answers

To convert into degrees:

1. You should know the percentage of the angle with respect to 2pi:

(7pi/9) / (2pi) = 7/18

2. Then, multiply the ratio to the 2pi angle in degrees, which is 360

360 * (7/18) = 140

(7pi/9)(180/pi)
140°

multiplying by 180/pi give you a degree measure

Find a quadratic model for the data in the table. Type your answer below. Show your work.

Answers

You have to solve 3 equations pretty much simultaneously here using the x and y values in the general form of the quadratic equation [tex]y=a x^{2} +bx+c[/tex]
Start with the first values of x=0 and y=5.1 to solve for c:
[tex]5.1=a(0) ^{2} +b(0)+c[/tex] so c = 5.1
Next use the second x and y values along with the value of c in the next equation:
[tex]3.03=a(1) ^{2} +b(1)+5.1[/tex] gives you
-2.07 = a + b. Solve this for a:
a = -2.07 - b
Finally use the third set of numbers with the c value AND the subbed value for a:
[tex]1.17=a(3) ^{2} +b(3)+5.1[/tex]
1.17 = 9(-2.07 - b)+ 3b + 5.1 which simplifies to:
1.17 = -18.63 - 9b + 3b + 5.1 which further simplifies to:
14.7 = -6b and b = -2.45
Now you have c and b, let's find a using one of the simplified equations:
-2.07 = a + b
-2.07 = a - 2.45
a = .38
So here's your equation:
[tex]y=.38 x^{2} -2.45x+5.1[/tex]

Find a and b so that the polynomial, p(x)=x^2+ax-b passes through the points (6,-9) and (1, 16)

Answers

The given equation is:

p(x) = x^2 + ax - b

We write this in terms of y:

y = x^2 + ax – b

To solve for the values of the constants a and b, we are given the following conditions:

When x = 6, y = -9

When x = 1, y = 16

From these conditions, we can formulate two equation by substituting the values of y:

-9 = 6^2 + a(6) – b

6a = b – 45 ---> 1

16 = 1^2 + a(1) – b

a = b + 15 ---> 2

Combining equations 1 and 2:

6 (b + 15) = b – 45

6b + 90 = b – 45

5b = -135

b = -27

calculating for a using equation 1:

a = b + 15

a = -27 + 15

a = -12

Answers:

a = -12

b = -27

Two sandboxes with the same area are shown. The equation w(3w+1)=5^2 represents the area of Sandbox 2 in terms of its width. Which is the approximate length of the longest side of Sandbox 2? Round the answer to the nearest hundredth of a meter.

A.) 2.72 meters

B.) 3.06 meters

C.) 9.16 meters

D.) 10.18 meters

Answers

sandbox 1 area = 5*5 = 25 square m

sandbox 2

25=w*(3w+1)=

3w^2+w-25=0

w=2.7248 (round to 2.72 m)

2.72*3=8.16+1 = 9.16

Longest side = 9.16 meters

Answer:

C.) 9.16 meters

Step-by-step explanation:

We are given that the two sandboxes have same area and the equation is given by 25 = w*(3w+1).

Now, we simplify this equation in order to find the value of unknown variable 'w'.

i.e. 25 = 3[tex]w^{2}[/tex]+w

i.e. 3[tex]w^{2}[/tex]+w-25=0

The two factors of this quadratic equation are w=2.72 and w= -3.05.

But, as 'w' represents the length of the box, so it cannot be negative.

Therefore, w = 2.72

So, the longest side of the box is (3w+1) = 3*2.72+1 = 9.16 meter

Hence, the length of longest side to the nearest hundredth is 9.16 meter.

A triangle has side lengths 9, 10, and 12. is it acute, obtuse, or right? explain.

Answers

Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be:
right if a² + b² = c²
аcute if a² + b² > c²
obtuse if a² + b² < c²

We have a=9, b=10 and c=12

a² + b² = 9² + 10² = 81 + 100 = 181
and
c² = 12² = 144

181 > 144 ⇒ аcute triangle.

Final answer:

By applying the Pythagorean theorem and comparing the square of the longest side to the sum of the squares of the other two sides, it is determined that a triangle with sides of 9, 10, and 12 is an acute triangle since 144 is less than 181.

Explanation:

To determine whether a triangle with side lengths of 9, 10, and 12 is acute, obtuse, or right, we can apply the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) equals the sum of the squares of the lengths of the other two sides. If this condition is met, the triangle is right-angled. If the square of the longest side is greater than the sum of the squares of the other two sides, the triangle is obtuse. Conversely, if the square of the longest side is less than the sum of the squares of the other two sides, the triangle is acute.

For this triangle, the side lengths squared are:

9² = 8110² = 10012² = 144

Adding the squares of the two shorter sides: 81 + 100 = 181.

Since 144 < 181, the square of the longest side (12²) is less than the sum of the squares of the other two sides, indicating that this triangle is acute.

The goal of any experiment is to test the hypothesis by adjusting the independent variables so you can see the trend of the dependent variable that you want to investigate. The independent variables are parameters that you manipulate. In this experiment, that would be the time of day. You have two independent variables: night and day. The speed of the mice is the parameter that you will measure. Once you do these set-up, you can conclude in the end the effect of the time of day on the speed of the mice.

The average of six numbers is 4. a seventh number is added and the new average is 5. what is the seventh number?

Answers

the average of 6 numbers is 4....
t/6 = 4.....t = 24 (the total of the 6 numbers)

(24 + x) / 7 = 5
24 + x = 35
x = 35 - 24
x = 11 <== ur 7th number

According to the question, the seventh number is 11.

Use the concept of average defined as:

Average, also known as the mean, is a statistical measure that represents the central value of a set of numbers. It is calculated by summing up all the numbers in the set and dividing the sum by the total count of numbers.

To find the seventh number,

If the average of six numbers is 4, then the total sum of those six numbers would be 6 multiplied by 4, which is 24.

Assume the seventh number is 'x'.

If the new average (after adding the seventh number) is 5, then the total sum of all seven numbers would be 7 multiplied by 5, which is 35.

To find the seventh number 'x',

Subtract the sum of the initial six numbers (24) from the sum of all seven numbers (35).

This gives us 35 - 24 = 11.

Hence,

The seventh number is 11.

A roller coaster climbs 84 feet on the first hill then drop 60 feet down. on the second hill the roller coaster climb another 32 feet then drops 44 feet. what is te height at the end of the second hill ?

Answers

84 - 60 = 24
24 + 32 = 56
56 - 44 = 12

The answer is 12.

Answer:

12 feet.

Step-by-step explanation:

A roller coaster climbs the height on first hill = 84 feet.

Then drops down = 60 feet.

Height gained by the roller coaster = 84 - 60

= 24 feet

On other hill roller coaster climbs = 32 feet

Height gained by the roller coaster = 24 + 32 = 56 feet.

It drops again to the height = 44 feet

So the final height at the second hill = 56 - 44

= 12 feet

Therefore, height of roller coaster on the second hill is 12 feet.
