Answer:

width=71km, length=177.5km

Step-by-step explanation:

Let x be the width of the farm.

Then the length of the farm will be 2.5x.

perimeter of farm in terms of x=2.5x+2.5x+x+x=7x

perimeter of farm in terms of x=perimeter of farm

7x=497

x=71

width=71km

length=71×2.5=177.5

The monthly payment is  $86.55. The result is obtained by using the formula for simple interest.

The simple interest of an amount of money can be counted by the following formula.

I = P × r × t

Where

A motocross company offers a loan to buy an ATV for $4,000. Loan Offer 9.3% Simple Interest.

If it is for 6 years, find the monthly payment!

We have

It is not mentioned that the simple interest apply per year or per month. We assume the simple interest is per year. It will be

I = P × r × t

I = $4,000 × 9.3% × 6

I = $2,232

The total money to be paid will be

A = P + I

A = $4,000 + $2,232

A = $6,232

The monthly payment is

MP = A/t

MP = $6,232/(6 × 12)

MP = $6,232/72

MP = $86.55

Hence, the person who borrows for $4,000 to buy an ATV should pay $86.55 each month for 6 years.

Answer:

Step-by-step explanation:

In a triangle, the sides have a ratio of 3:7:10. If the perimeter is 210 feet, what is the length of the longest side in feet? (A) * 10.5 (B) 31.5 (C) (D) 105​

[210 : (3 + 7 + 10)] x 10 = 105 ft (your answer)

Step-by-step explanation:

the ratio tells us into how many units the total amount is split and then distributed among the different parts or members of the ratio.

3:7:10 means there are 3+7+10 = 20 units of length.

210 ft is the total of all lengths.

this is now split into these 20 units.

that means one unit of length for the ratio is

210/20 = 10.5 ft

the longest side is clearly the one with 10 units in the ratio.

so, it has

10×10.5 = 105 ft

Answer:

  (a)  -1/2x +3 = 3x -4

Step-by-step explanation:

Given a graph of two lines, you want to know which equation it is showing the solution for.

The blue line has a slope of -3/6 = -1/2, and a y-intercept of +3, so its slope-intercept equation is ...

  y = -1/2x +3

This expression is seen on the left side of the equal sign for the first choice, and is not seen anywhere else.

By way of confirmation, the red line has slope 3/1 = 3 and a y-intercept that is a negative value less than -2. It is reasonable to say its slope-intercept equation is ...

  y = 3x -4

This expression matches the right side of the equal sign for the first choice.

The solution to the system of these two equations might reasonably be found by equating the expressions for y:

  -1/2x +3 = 3x -4

The standard form of the equation for the given p value and theta is equal to -x + y = 26√2.

Standard form of the equation is :

x cosθ + y sinθ = p

Here p = 26 and theta 'θ' = 3π /4

Substitute the value in the standard form we get,

x cos (3π/4 ) + y sin( 3π /4 ) = 26

⇒ x cos ( π - π/4 ) + y sin ( π - π/4 ) = 26

⇒ - x cosπ/4 + y sinπ/4 = 26

Substitute the value of cosπ/4 and sinπ/4 is equal to 1/√2 we get,

⇒ -x /√2 + y / √2 = 26

⇒ -x + y = 26√2

Therefore, the standard form of the equation is equal to -x + y = 26√2.

A wheel of cheese has a radius of 7 inches and a height of 3 inches

The approximate surface area of this wheel of cheese is 458.4 square inches.

To get the surface area of a cylinder,  we have to calculate the area of the lateral surface and add the areas of the two circular end faces.

The lateral surface area of a cylinder is calculated as 2 * pi * r * h, where r is the radius and h is the height.

So the lateral surface area in this scenario would be: 2 * 3.14 * 7 * 3 = 150.52 square inches.

The area of the two end faces must then be calculated. we know, Pi * r^2, where r is the radius, gives the area of a circle.

So the area of each end face in this situation would be 3.14 * 7^2 = 153.94 square inches.

Total surface area= lateral surface area + end face area

=150.52 + 153.94 + 153.94 = 458.4 square inches (approximately)

[tex]w = \frac{5}{3} r[/tex]

[tex]w + r = 32[/tex]

[tex] \frac{5}{3} r + r = 32[/tex]

If cos(x) = 8/17, then sin(x) = 15/17. Use the identity [tex]\sin^2(\text{x}) + \cos^2(\text{x}) = 1[/tex] to determine this.

If cos(y) = 3/5, then sin(y) = 4/5 using that same identity.

sin(x-y) = sin(x)cos(y) - cos(x)sin(y)

sin(x-y) = (15/17)*(3/5) - (8/17)*(4/5)

To simplify further, we rationalize the denominator

Multiply both the numerator and denominator by √281

sin( α ) = (16 × √281 ) /(√281 × √281 )

sin( α ) = (16 × √281 ) / 281

sin( α ) = (16√281 )/281

The length of one edge of the cube is 8 cm and the radius of the sphere is 9 cm.

What is the cube root?

The cube root of a number is a value that when multiplied by itself thrice or three times produces the original value. For example, the cube root of 27, denoted as 3√27, is 3, because when we multiply 3 by itself three times we get 3 x 3 x 3 = 27 = 33.

The surface area of a cube is given by the formula:

A = 6 * a^2

where A is the surface area and a is the length of one edge of the cube.

So, in this case:

384 = 6 * a²

Dividing both sides by 6:

64 = a²

Taking the square root of both sides:

a = 8 cm

So the length of one edge of the cube is 8 cm.

The formula for the volume of a sphere is:

V = (4/3) * π * r³

where V is the volume, π is Pi (approximately equal to 3.14), and r is the radius of the sphere.

So, in this case:

729 = (4/3) * π * r³

Dividing both sides by (4/3) * π:

729 / (4/3) * π = r³

Taking the cube root of both sides:

r = pow(729 / (4/3) * π, 1/3) = 9 cm

So the radius of the sphere is 9 cm.

The cube root of 729 is 9.

Hence, the length of one edge of the cube is 8 cm and the radius of the sphere is 9 cm.
