The perimeter of the picnic area is 107 yards

A triangular picnic area has the side lengths of 45, 31 and 31 yards; To the nearest yard, what amount of fencing is needed to surround the perimeter of the picnic area? 95 yards 107 yards 160 yards 190 yards

From the complete question, we have:

Shape: Triangle

Side lengths = 45 yards, 31 yards, 31 yards

The perimeter is the sum of the side lengths.

So, we have:

Perimeter = 45 + 31 + 31

Evaluate

Perimeter = 107

Hence, the perimeter of the picnic area is 107 yards

Answer:(x-4)^2+(y+2)^2=121

Step-by-step explanation:

eqaution of circle is this

(x-h)^2+(y-k)^2=r^2

(x-4)^2+(y--2)^2=r^2

and 2 negatives make positive

(x-4)^2+(y+2)^2=r^2
and r^2=121

(x-4)^2+(y+2)^2=121

This is incorrect because 1 meter is 100 centimeters. But then when you keep going and when you get to 4 meters, you would get 400.

For example:

Straight angles are straight lines which equal 180 degrees

Answer:

true it is equals 180 for that angle

Answer:

Step-by-step explanation:

a straight line equals 180°. so if one side is 117°, the other side would have to add up to 180.

180-117=63

And you can kind on figure out what is the same as the other angles. Hope his helps

Step-by-step explanation:

The slope formula from 2 points is:

m=(y2-y1)/(x2-x1)

So input the numbers:

m = (6 - -2) / (5 - 2)

Solve within parenthesis:

m = (8) / (3)

Then divide!
8/3 = 2 2/3

the slope of the line is 2 and 2/3

The median of the number recorded in the question is 51.5 feet. This is obtained by dividing the sum of two numbers that occur centrally in half.

The central value in a list ordered from smallest to largest is the median of a set of values.

The formula for the Inter-quartile range is given as:

IQR = Q₃- Q₁ (that is Median of the Upper Half Less the Median of the lower half)

Step 1 - First, let's arrange the numbers sequentially

→  40, 40, 47, 49, 50, 53, 55, 57, 63, 76

Step 2 - Determine the upper and lower halves and their median

If the Lower half is  40, 40, 47, 49, 50, then it's median is 47

If the Upper half is   53, 55, 57, 63, 76, then its median is 57.

Hence:

IQR = 57 - 47

= 10 feet.

No, the friends didn't perform better in the second round because the was a significant drop in the median and the IQR. The median dropped from 51.5 to 47 and the IQR from 10 to 6.

It can be concluded that the distance in the second set of data is less variable when juxtaposed with those form the first set.

[tex]\qquad \sf  \dashrightarrow \: 30[/tex]

So, the equivalent expression is 30

Answer:

30

Step-by-step explanation:

Let us divide the whole expression by 5. Then we must multiply the whole expression by 5 to obtain the same value as before.

Thus, we get the following expression:

[tex]\implies\huge\text{[}\dfrac{5(z+4)+5(2-z)}{5}\huge\text{]} \times 5[/tex]

[tex]\implies\huge\text{[}\dfrac{(z+4)+(2-z)}{1}\huge\text{]} \times 5[/tex]

Now, open the inner-most parentheses as the expression inside the inner-most parentheses, cannot be simplified further.

[tex]\implies\huge\text{[}\dfrac{z+4+2-z}{1}\huge\text{]} \times 5[/tex]

It should be noted that any number being subtracted from the same number is equivalent to 0. Therefore, we get the following expression:

[tex]\implies\huge\text{[}\dfrac{4+2}{1}\huge\text{]} \times 5[/tex]

Simplify the expression inside the long brackets.

[tex]\implies\huge\text{[}\dfrac{6}{1}\huge\text{]} \times 5[/tex]

Now, we can open the long brackets and simplify the product of 6/1 and 5.

[tex]\implies\huge\text{[}\dfrac{6}{1}\huge\text{]} \times 5 = \dfrac{6 \times 5}{1} = \dfrac{30}{1} = 30[/tex]

Therefore, the simplified expression is 30.
