Answer: calculate the perimeter of the rectangular park do 2{400)+2(200)

then find the answer then times 2 the answer

Step-by-step explanation:

for second one with the diagonal use the Pythagorean theorem do 400sqared + 200squared then square root the answer

Answer: ~447 meters

Explanation: Since it is a rectangular park, there are 4 right angles. By having a diagonal through the rectangle, we have formed two right triangles. We know the length and width of the park but we need to know the diagonal. We can use the Pythagorean Theorem a^2+b^2=c^2.

By substituting 400 for a and 200 for b (or 200 for a and 400 for b, it doesn’t matter), we get that 160000+40000=c^2 or 200000=c^2. We then take the sqrt of each side to arrive at c=447.2135955... or about 447 meters

This is the example my teacher used. However, I still don't understand what makes the integers even or odd. I was hoping someone
kow [346]

Answer:

<h2>Here's what makes an integer odd:</h2>
  • It is NOT a multiple of 2.
  • When divided by 2, the quotient would be a decimal or have a remainder or fraction.

<h2>Here's what makes an integer even:</h2>
  • It is a multiple of 2.
  • When divided by 2, the quotient has a whole number.

<em>The odd numbers from one to 10 are: 1, 3, 5, 7, 9.</em>

<em>The even numbers from one to 10 are: 2, 4, 6, 8, 10. </em>

  • With big numbers, if it ends with any of the odd numbers from one to ten, listed above, it would be odd. This goes for the same with even.
<h2>With the x + 2, x + 4, etc:</h2>
  • An odd number and even number has a pattern....

[odd, even, odd, even, odd...] [1, 2, 3, 4, 5]

  • So, if x was an odd number, adding it by 2, 4, 6, etc. will result in another odd number.

Here's an example:

x= 17\\x + 2 = ?\\(17) + 2 = 19

<em>See how x is an odd number and the sum of the number and two makes another odd number? </em>

The same can go with an even number:

x=2\\x + 6 = ?\\(2) + 6= 8

<em>See how x is an even number and the sum of the number and six makes another even number? </em>

I hope my answer helps you understand even and odd numbers.

Help! Directions too please!:)
NISA [10]
Slope of function B is "rising" 3 and going over to the right by 1. Representing the slope as 3/1 = 3.

Slope of function A is already giving. If you multiply the slope of function B by 2, it will equal the slope of Function A

A new car costs $8000 at full price. With a sales tax of 5.75%, how much will the car cost in total?​
ioda

Answer:

$8460

Step-by-step explanation:

So for this problem we will use the base price of $8000 and add the additional cost of the 5.75% to find the total cost for the car.

So, to find the 5.75%, we simply multiply 8000 by .0575 to get 460.

So 8000 + 460 = 8460.

Thus, the total price of the car would be $8460.

Cheers.

If you divide 6! by 4! you are evaluating P(6, 4)
Aleks [24]
When you're evaluating P(n, k), you are essentially saying there are n objects and you will need to arrange them in k spaces.

This is essentially the same as: ^{6}P_4, which follows the formula:

P(6, 4) = ^{6}P_4 = \frac{6!}{(6 - 4)!} = \frac{6!}{2!}
If you're dividing by 4!, you are evaluating P(6, 2)
