a large farm has 75 acres of wheat and 62.5 acres of corn. the farm crew can harvest the wheat from 12 acres and the corn from 10 acres per day. in how many days will all of the fields be harvested
Answer:
7 days
Step-by-step explanation:
First let's start with the wheat. If you know that there is 75 acres of wheat, and you can harvest 12 acres in one day, all you have to do is 75 divided by 12.
This would get you at 6.25, but a whole day would be 7.
Corn, you know that there is 62.5 acres. Same thing, you do 62.5/10, and will get you around 7 again.

The function f(x) = 50(0.952)x, where x is the time in years, models a declining feral cat population. How many feral cats will there be in 9 years?
about 51 feral cats
about 459 feral cats
about 428 feral cats
about 32 feral cats
You would solve the problem by substituting 9 for x in the equation f(x) = 50(0.952)^x. After calculating it, the estimated number of feral cats in 9 years is 32.
Explanation:The function given is f(x) = 50(0.952)^x, which models a declining feral cat population. To find out how many feral cats there will be in 9 years, plug in 9 for x in the formula: f(9) = 50(0.952)^9. Upon calculation, this equals approximately 32, hence, there would be about 32 feral cats after 9 years.

The model f(x) = 50(0.952)x is used to predict the declining feral cat population over time. By substituting x = 9, we can predict there will be about 32 feral cats in 9 years.
Explanation:The function f(x) = 50(0.952)x describes the declining population of feral cats over years. To determine the number of feral cats in 9 years, we substitute x = 9 in the function.
Therefore, f(9) = 50 * (0.952)9.
When you compute this, you get approximately 32, so at the end of 9 years, we expect about 32 feral cats.

Brian and Chris went together to Target to find party favors for a birthday party they are throwing together. Brian found 4 items that cost the same amount. Chris bought 3 items that each cost $2.50 more than Brian’s items each cost. Brian and Chris both paid the same amount of money. What was the individual cost of each person's items?
(a) Write an equation. Let x represent the cost of one of Brian's items.
(b) Solve the equation. Show your work.
(c) Check your solution. Show your work.
(d) State the solution in complete sentences.
Let us assume Brian's one item cost = $ x.
Chris one item cost is $2.50 more than Brian’s items each cost.
Therefore, Chris one item cost is = $(x+2.50).
Total cost of Brian's 4 items = 4*x = 4x.
Total cost of Chris's 3 itmes = 3*(x+2.50) =3(x+2.50)
It is said that Brian and Chris both paid the same amount of money.
Therefore,
Total cost of Brian's 4 items = Total cost of Chris's 3 itmes.
a) We can setup an equation now,
4x = 3(x+2.50), where x represent the cost of one of Brian's items.b) Let us solve above equation for x.
4x = 3(x+2.50)
distributing 3 over (x+2.50), we get
4x = 3x + 7.50.
Subtracting 3x from both sides we get
4x-3x = 3x-3x =7.50.
x = 7.50.Therefore, the cost of one of Brian's items = $7.50.
Chris one item cost is $2.50 more than Brian’s items each cost.
Chris one item cost is = 7.50 +2.50 = $10.00.
c) Plugging x=7.50 in the equation we get to check the solution.
4x = 3(x+2.50)
4(7.50) = 3(7.50+2.50).
30 = 3(10.00)
30=30.
Therefore, solution x=7.50 is correct.
d) The cost of one of Brian's items is $7.50 and Chris's one item cost is $10.00.Answer:
Brians is $7.50 and chris is $10.00!

For what value of x will the line passing through the following pairs of points be vertical? F(3−2x, 12) and G(x+9, 7)
Answer: x = -2
Step-by-step explanation:
vertical line means it will be x = ___
Set the x-values equal to each other and solve for x.
3 - 2x = x + 9
+2x +2x
3 = 3x + 9
-9 -9
-6 =3x
[tex]\frac{-6}{3} = \frac{3x}{3}[/tex]
-2 = x
The line passing through the points F(3−2x, 12) and G(x+9, 7) will be vertical if x = -2
For two points (X₁, Y₁) and (X₂, Y₂) to form a vertical line, the x-coordinates must be equal
The given points are F(3-2x, 12) and G(x+9, 7)
X₁ = 3 - 2x
X₂ = x + 9
For the points to form a vertical line:
X₁ = X₂
3 - 2x = x + 9
Collect like terms
x + 2x = 3 - 9
3x = -6
Divide both sides by 3
3x / 3 = -6/3
x = -2
The line passing through the points F(3−2x, 12) and G(x+9, 7) will be vertical if x = -2

Show all your work plz!! Use the Substitution method to solve the system of equations. x + y = 20 30x + 25y = 550
x + y = 20
30x + 25y = 550
Using the first equation, we can find a temporary value of x.
x = 20 - y
Now that we have a value of x, we can plug it into the second equation to find the exact value of y.
30x + 25y = 550
30(20 - y) + 25y = 550
Distributive property.
600 - 30y + 25y = 550
Combine like terms.
600 - 5y = 550
Add 5y to both sides.
600 = 550 + 5y
Subtract 550 from both sides.
50 = 5y
Divide both sides by 5.
y = 10.
Now we can plug the value of y into the original equation to find the value of x.
10 + x = 20
Subtract 10 from both sides.
x = 10
The value of x is equal to 10, and the value of y is also equal to 10.
solution is (x, y ) = (10, 10)
given
x + y = 20 → (1)
30x + 25y = 550 → (2)
from (1) y = 20 - x → (3)
substitute y = 20 - x in (2)
30x + 25(20 - x) = 550
30x + 500 - 25x = 550
5x + 500 = 550 ( subtract 500 from both sides )
5x = 50 ( divide both sides by 5 )
x = [tex]\frac{50}{5}[/tex] = 10
substitute x = 10 in (3) : y = 20 - 10 = 10
thus x = 10, y = 10 is the solution

Substitute in the values of
a, b, and c.
6^2−4(1⋅9)
Evaluate the result to find the discriminant.
36-4(9)
36-36
0
The discriminant of the quadratic equation p²+6p+9=0 is zero, suggesting that it has exactly one real, repeated solution.
The discriminant of the quadratic equation p²+6p+9=0 is calculated using the formula D=b²-4ac, where a, b, and c are the coefficients of the quadratic equation ax²+bx+c=0. In this equation, a=1, b=6, and c=9. Substituting these values into the discriminant formula gives us:
D = b² - 4ac
D = (6)² - 4(1)(9)
D = 36 - 36
D = 0
The discriminant is zero, which indicates that the quadratic equation has one real, repeated solution, meaning the parabola touches the x-axis at a single point.

The Navy Pier Ferris has the circumference is 56% of the circumference of the first Ferris wheel.
The Navy Pier Ferris Circumference = 439.6 feet
Let's assume "x" be circumference of first Ferris wheel.
56% of x = 439.6
0.56 x = 439. 6 [56% = 0.56]
x = 439.6/0.56
x = 785.
Therefore, the circumference of the first Ferris wheel is 785.
It is diameter = 785/3.14 = 250 feet
So it is radius = 250/2 = 125 feet.
Part C)
The circumference = 785 feet
Speed = Distance/Time
Speed = 785/9
Speed = 87.2 feet per minute.
That's it. Hope you will understand the steps.

Hey there!

= 25% * 1,000
= 25/100 * 1,000/1
= 25 ÷ 5 / 100 ÷ 5 * 1,000/1
= 5 / 20 * 1,000/1
= 5 ÷ 5 / 20 ÷ 5 * 1,000/1
= 1 / 4 * 1,000 / 1
= 1/4 * 1,000/1
= 1(1,000) / 4(1)

= 1,000 ÷ 4
= 250
Therefore, your answer should be: 250

natasha is filling a swimming pool . the water rises 1/3 foot every hour. the pool is 4 feet deep how long will it take to fill the pool?
The water is rising at a rate of 1/3 foot per hour. That means it will take 3 hours to fill 1 foot. Now multiply 3 times 4, because it takes 3 hour for every foot. That equals 12. That means it will take Natasha 12 hours to fill the 4 foot pool. Hope that helps!

find the number of sides of a regular polygon if the measure of an interior angle is 157.5°
In a polygon with n sides, the sum of the measures of the interior angles, S, is
[tex] S = (n - 2)180 [/tex]
In a regular polygon with n sides, the measure of each interior angle, a, is the sum of the measures of the interior angles divided by the number of sides, or
[tex] a = \dfrac{(n - 2)180}{n} [/tex]
In this case, we know the measure of one angle, a = 157.5°, so we plug it into the second formula and solve for n.
[tex] a = \dfrac{(n - 2)180}{n} [/tex]
[tex] 157.5 = \dfrac{(n - 2)180}{n} [/tex]
[tex] 157.5n = (n - 2)180 [/tex]
[tex] 157.5n = 180n - 360 [/tex]
[tex] -22.5n = -360 [/tex]
[tex] n = 16 [/tex]
Answer: The polygon has 16 sides.
In order to find the number of sides for a regular polygon with an interior angle of 157.5°, we use the formula n = 360 / (180 - 157.5), which gives us n = 16. Hence, the polygon has 16 sides.
Explanation:In mathematics, the number of sides of a regular polygon can be found if the measure of an interior angle is known. Given that the interior angle is 157.5° we use the formula for calculating the measure of an interior angle in a regular polygon:
n = 360 / (180 - 157.5)
Where 'n' represents the number of sides in the polygon. Substituting 157.5 into the formula, the calculation becomes n = 360 / 22.5. By performing the calculation, we find that n = 16. Therefore, the regular polygon with an interior angle of 157.5° has 16 sides.
