The farmer can 9 days more than 31 days.

given,

farmer buy 1000 pounds of hay

if cow eats 25 pounds of hay per day .

here, 25 x 31 =775

which is less than 1000 ,so that the farmer can feed the cow more than 31 days

1000-775=225

225/25=9

therefore the farmer can 9 days more than 31 days.

There are four basic properties of numbers: commutative, associative, distributive, and identity. You should be familiar with each of these.

distributive property ;

According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

The commutative property states that the change in the order of two numbers in an addition or multiplication operation does not change the sum or the product.

The horizontal distance as a function of d can be given as h = √(d + 7200) (d - 7200).

It is given in the question that:

Height at which blimp is flying (AB)= 7200 feet

The slanted distance to the pagoda (BC) = d feet

The horizontal distance (AC) = h

Let the angle made between slanted distance and horizontal distance be θ.

So, cosθ = AC/BC

cosθ = h/d

and also, sinθ = AB/BC

sinθ = 7200/d

Now, we know from the first trigonometric identity that cos²θ = 1 - sin²θ.

=> (h/d)² = 1 - (7200/d)²

=> (h/d)² = (d² - 7200)/d²

=> h² = d² - 7200

=> h = √(d² - 7200)

=> h = √(d + 7200) (d - 7200)

Thus, the horizontal distance as a function of d can be given as h = √(d + 7200) (d - 7200).

Answer:

11.58 years

6.82 years

Step-by-step explanation:

Compound interest can be represented as: [tex]A=P(1+\frac{r}{n})^{nt}[/tex] where P = initial amount, r=interest rate, n=compounds in each time unit, t = time (usually years)

If you think about it the: [tex](1+\frac{r}{n}})^{nt}[/tex] represents the overall interest being applied to the principal amount.

This would have to be equal to 2, for it to be doubled, so let's set that equal to 2

[tex]2=(1+\frac{r}{n})^{nt}[/tex]

Now let's solve for "t", first let's take the log of both sides

[tex]log(2)=log([1+\frac{r}{n}]^{nt})[/tex]

Now let's use log properties, specifically the exponent one to rewrite

[tex]log(2)=nt *log(1+\frac{r}{n})[/tex]

Now divide both sides by the log(1 + r/n) and n

[tex]t=\frac{log(2)}{n*log(1+\frac{r}{n})}[/tex]

Our "n" is going to be the same for both equations, 12 since it's compounded monthly

The interest will be a bit different, but in the first case it will be 6% which is 0.06

[tex]t=\frac{log(2)}{12*log(1+\frac{0.06}{12})}[/tex]

simplifying this we get

[tex]t\approx11.581[/tex]

Rounding this we get: [tex]t=11.58[/tex]

Now let's do this to the other equation:

[tex]t=\frac{log(2)}{12*log(1+\frac{0.102}{12})}[/tex]

simplifying this we get:

[tex]t\approx 6.824[/tex]

approximately 6.82

Commutative Property of Multiplication

Step-by-step explanation:

The Commutative Property of Multiplication essentially states that constants and variables can be multiplied in any order and the product will not change.

For example, the multiplication of 5 x 4 = 20 and 4 x 5 = 20 are equivalent. No matter what, you will get the same product.

Both equations utilize the distributive property, which states that an expression a(b ± c) can be multiplied to create ab ± ac. As such, we can rearrange the a to either the front or end of the expression and retrieve the same results.

The number of apple trees the orchard have is 3533.

The apple orchard  has honey crisp trees and McIntosh trees.

The orchard has 1603 honey crisp trees.

It has 327 more McIntosh trees than honey crisp trees.

Therefore,

number of honey crisp trees = 1603

number of McIntosh trees = 327 + 1603

number of McIntosh trees = 1930

Therefore, the number of apples trees the orchard have can be calculated as follows:

number of apples trees = number of McIntosh trees + number of honey crisp trees

number of honey crisp trees = 1603

number of McIntosh trees = 1930

number of apples trees = 1930 + 1603

number of apples trees = 3533

Step-by-step explanation:

The perimeter of a two-dimensional shape is the distance all the way around the outside.  

To find the perimeter of a polygon, sum the lengths of its sides.

Use the distance formula to find the length of each side.

[tex]\boxed{\begin{minipage}{4.7 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

Given points:

Use the distance formula to find the length of each side of ABC:

[tex]\begin{aligned}AB & = \sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& = \sqrt{(2-(-2))^2+(5-1)^2}\\& = \sqrt{4^2+4^2}\\& = \sqrt{16+16}\\& = \sqrt{32}\end{aligned}[/tex]

[tex]\begin{aligned}BC & = \sqrt{(x_C-x_B)^2+(y_C-y_B)^2}\\& = \sqrt{(5-2)^2+(1-5)^2}\\& = \sqrt{3^2+(-4)^2}\\& = \sqrt{9+16}\\& = \sqrt{25}\\& = 5\end{aligned}[/tex]

[tex]\begin{aligned}AC & = \sqrt{(x_C-x_A)^2+(y_C-y_A)^2}\\& = \sqrt{(5-(-2))^2+(1-1)^2}\\ & = \sqrt{7^2+0^2}\\ & = \sqrt{49}\\ & = 7\end{aligned}[/tex]

To find the perimeter, sum the sides:

[tex]\begin{aligned}\sf Perimeter & = AB+BC+AC\\& = \sqrt{32}+5+7\\& = 4\sqrt{2}+12\\& = 17.7\;\sf units\;(nearest\:tenth)\end{aligned}[/tex]

Given points:

After plotting the given points, it is clear that the polygon is a parallelogram. As the opposite sides of a parallelogram are equal in length:

Therefore, we only need to find the length of two sides to calculate the perimeter.

Use the distance formula to find AB and BC:

[tex]\begin{aligned}AB & = \sqrt{(1-(-3))^2+(6-5)^2}\\& = \sqrt{4^2+1^2}\\& = \sqrt{16+1}\\& = \sqrt{17}\end{aligned}[/tex]

[tex]\begin{aligned}BC & = \sqrt{(3-1)^2+(-2-6)^2}\\& = \sqrt{2^2+(-8)^2}\\& = \sqrt{4+64}\\& = \sqrt{68}\end{aligned}[/tex]

Therefore, the perimeter of ABCD is:

[tex]\begin{aligned}\sf Perimeter & = 2(AB+BC)\\& = 2(\sqrt{17}+\sqrt{68})\\& = 6\sqrt{17}\\& =24.7\;\sf units\;(nearest\:tenth)\end{aligned}[/tex]
