The answer is 32m.

the way you would find out is by adding up all the measurements. so you would do

9+5+7+11

which would get you the final answer of 32m. make sure you dont forget the units.

A farmer plans to fence a rectangular corral. The diagonal distance from one corner of the corral to the opposite corner is five
garik1379 [7]

Answer:

Length of diagonal is 7.3 yards.

Step-by-step explanation:

Given: The diagonal distance from one corner of the corral to the opposite corner is five yards longer than the width of the corral. The length of the corral is three times the width.

To find: The length of the diagonal of the corral.

Solution: Let the width of the rectangular garden be <em>x</em> yards.

So, the length of the diagonal is x+5

width of the rectangular corral is 3x

We know that the square of the diagonal is sum of the squares of the length and width.

So,

(3x)^{2} +x^{2} =(x+5)^{2}

9x^{2} +x^{2} =x^{2}+10x+25

9x^{2}-10x-25=0

9x^{2}-10x-25=0

x=\frac{-b\pm\sqrt{b^{2} -4ac} }{2a}

x=\frac{10\pm\sqrt{(-10)^{2} -4(9)(-25)} }{2(9)}

x=\frac{10\pm\sqrt{100}}{18}

Since, side can't be negative.

x=\frac{5}{9}+\frac{5}{9}\sqrt{10}

Now, length of the diagonal is

5+\frac{5}{9}+\frac{5}{9}\sqrt{10}

Hence, length of diagonal is 7.3 yards.

Hi! Can someone help me please.
Sati [7]

Answer:

27 inches

Step-by-step explanation:

We are using the Pythagorean theorem

a^2 +b^2 = c^2  where c is the hypotenuse

We are given the diagonal, which is the hypotenuse and a leg

36^2 + b^2 = 45^2

Subtract 36^2 from each side

36^2 + b^2 - 36^2 = 45^2 - 36^2

b^2 = 45^2 - 36^2

     b^2 =2025-1296

          b^2 =729

Take the square root of each side

sqrt(b^2) = sqrt(729)

b =27

Set up Proportion and solve for X
Galina-37 [17]

Answer:

x = 9

Step-by-step explanation:

Assuming the rectangles are similar

13           x

------ = ---------

130         90

Using cross products

13*90 = 130*x

Divide each side by 130

13*90/130 = x

x = 9

What will the finance charge be on Hannah's computer purchase? (Do not include<br> sales tax)
k0ka [10]

Answer:

She would be paying $2,622 total.

Step-by-step explanation:

1. To get how much she'd be paying for 24 months, all you have to do is multiply 24 times 95.

2. To get the down payment you had to ask yourself what's 15% of 2,280. 15% of 2280 is 342.

3. Add those together and you'd get the total payment.

Simple.

Oh and gimme Brainliest if it's correct.
