Answer:
18
Step-by-step explanation:
9+9=18 both sides of the rectangle is 9 so the top is longer which means 18
The formula for finding area of a triangle is:
![\frac{1}{2}bh](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7Dbh%20%20)
The base is 8 feet. The area is 48 ft². Put that into the formula:
![\frac{1}{2} b8 = 48](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20b8%20%3D%2048%20)
Remember that you have to multiply the base × height by
, which is the same as dividing by 2. To find the height, you need to multiply the area by 2, instead of dividing.
![Area = 48 sq\ ft^{2} \\ 48 \times 2 = 96](https://tex.z-dn.net/?f=%20Area%20%3D%2048%20sq%5C%20ft%5E%7B2%7D%20%5C%5C%2048%20%5Ctimes%202%20%3D%2096%20)
That means the base × height is equal to 96. You already know the height. To find the base, divide the (base × height) by the height. The height is 8.
![96 \div 8 = 12](https://tex.z-dn.net/?f=%2096%20%5Cdiv%208%20%3D%2012%20)
That means the base of the triangle is 12 ft
<h3>CHECK</h3>
![\frac{1}{2}bh](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7Dbh%20%20)
Base = 12
Height = 8
Put that into the formula:
✔
BASE = 12 ft
Answer: 8x-15
Step-by-step explanation:
First you multiply 2x by 4x=8x
Then you multiply -3 by 5=-15
8x-15
Mean: 11
Median: 9
Mode: 7
Mean is when you add up all of the numbers, then you take the sum you get and divide by the amount of numbers you have. So in this case, it’d be 154 (the sum) divided by 14 (the amount of numbers you have).
Median is when you put all of your numbers in ascending order and then find the middle number. In this case, the amount of numbers we had were even, so the middle numbers were 8 and 10. In between of these two numbers, is the number 9. So as a result, 9 is your answer.
Mode is the number that you see the most in a set of number. In this case, 7 is repeated 3 times, unlike other numbers, which happens to be the most. So, 7 is your answer for the mode.
