To calculate mean: Just add up all the numbers, then divide by how many numbers there are.345 + 673 + 728 +775 + 822 +827 +839 + 951 = 5960/8 = 745
633 + 673 + 728 +775 + 822 +827 +839 + 951 = 6248/8 = 781781- 745 = 35 It increases by 35To find the Median, place the numbers in value order and find the middle. BUT, with an even amount of numbers things are slightly different. In that case we find the middle pair of numbers, and then find the value that is half way between them. This is easily done by adding them together and dividing by two. 345 673 728 775 822 827 839 951 The median = 822-775 /2
The median =23.5After the change633 673 728 775 822 827 839 951 The median = 822-775 /2
The median =23.5The median stays the same.

The sides of a quadrilateral are 3, 4, 5, and 6. Find the length of the shortest side of a similar quadrilateral whose area is 9

Georgia [21]

Answer:

9 units.

Step-by-step explanation:

Let us assume that length of smaller side is x.

We have been given that the sides of a quadrilateral are 3, 4, 5, and 6. We are asked to find the length of the shortest side of a similar quadrilateral whose area is 9 times as great.

We know that sides of similar figures are proportional. When the proportion of similar sides of two similar figures is $\frac{m}{n}$ , then the proportion of their area is $\frac{m^2}{n^2}$ .

We can see that length of smaller side of 1st quadrilateral is 3 units, so we can set a proportion as:

$\frac{x^2}{3^2}=\frac{9}{1}$

$\frac{x^2}{9}=\frac{9}{1}$

$x^2=9\cdot 9$

$x^2=81$

Take positive square root as length cannot be negative:

$\sqrt{x^2}=\sqrt{81}$

$x=9$

Therefore, the length of the shortest side of the similar quadrilateral would be 9 units.

65^2 = 39^2 + b^2

4225 = 1521 + b^2

b^2 = 4225 - 1521

b^2 = 2704

b = √2704

b = 52 inches

Plss help me do this giving brainliest

Hatshy [7]

Answer:

Step-by-step explanation:

A right triangle has a right angle in it. The base and height are then the sides that make the right angle. You can change the 2.5 to a fraction 5/2 or leave it a decimal and just use your calculator. Once the base and height are drawn, you don't have to calculate the hypotenuse (the longest side) just connect the third side. See image. Also, def do this on graph paper it's easier. The new triangle should be bigger than the original this time bc 2.5 is bigger than 1 and so it makes your shape bigger.

Aliun [14]

To determine the equivalent ratios, we would reduce each ratio to its lowest term. This involves dividing by a common factor till it is no longer divisible. Therefore,
