Fourths, (1/4), (.25), (25%)
Answer:
Area of the wall without the doorway = 67.5 - 21 = 46.5 ![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
Step-by-step explanation:
i) let length of smaller side of trapezoidal wall, a = 22 feet
ii) let length of longer side of trapezoidal wall, b = 23 feet
iii) height of trapezoidal wall, h = 3 feet
iv) area of trapezoidal wall =
=
= 22.5
3 = 67.5 ![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
v) area of door = 7
3 = 21 ![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
vi) Area of the wall without the doorway = 67.5 - 21 = 46.5 ![feet^{2}](https://tex.z-dn.net/?f=feet%5E%7B2%7D)
Answer:
7
Step-by-step explanation:
1) for '8'; '3'; and '10':
8/2+3+3=10
2) for '2'; '5' and '11':
2/1+5+5=11
3) for '6'; '2' and '?':
6/2+2+2=7
Answer:
<h2>9.43</h2>
Step-by-step explanation:
The formula of a distance between two points:
![d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%7D)
We have the points (5, 4) and (-3, -1). Substitute:
![d=\sqrt{(-3-5)^2+(-1-4)^2}=\sqrt{(-8)^2+(-5)^2}=\sqrt{64+25}=\sqrt{89}\approx9.43](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B%28-3-5%29%5E2%2B%28-1-4%29%5E2%7D%3D%5Csqrt%7B%28-8%29%5E2%2B%28-5%29%5E2%7D%3D%5Csqrt%7B64%2B25%7D%3D%5Csqrt%7B89%7D%5Capprox9.43)
