A leg of a right triangle can never be greater then the hypotenuse
this formula will tell you if it's a valid right triangle
![{?}^{2} + {?}^{2} = {?}^{2}](https://tex.z-dn.net/?f=%20%7B%3F%7D%5E%7B2%7D%20%2B%20%7B%3F%7D%5E%7B2%7D%20%3D%20%7B%3F%7D%5E%7B2%7D%20)
the first two question marks are the legs of the triangle while the one after the = is the hypotenuse.
THE STEPS:
![{3}^{2} + { \sqrt{7}^{2} } = {4}^{2}](https://tex.z-dn.net/?f=%20%7B3%7D%5E%7B2%7D%20%2B%20%7B%20%5Csqrt%7B7%7D%5E%7B2%7D%20%7D%20%3D%20%7B4%7D%5E%7B2%7D%20)
![9 + {2.65}^{2} = 16](https://tex.z-dn.net/?f=9%20%2B%20%7B2.65%7D%5E%7B2%7D%20%3D%2016)
![{2.65}^{2} = 7](https://tex.z-dn.net/?f=%20%7B2.65%7D%5E%7B2%7D%20%3D%207)
![9 + 7 = 16](https://tex.z-dn.net/?f=9%20%2B%207%20%3D%2016)
ANSWER:
Answer:
i say 40 minutes
Step-by-step explanation: in the first 4 minutes she planted 7 flowers, in the next 8 minutes she planted 21 flower. so what i did was divide 70 by 7... since the amount of flowers is going up by 7's. so 70 divided by 7 is 10... now every 4 minutes you plant flowers so 10 by 4= 40 minutes
Answer:
Given
Edge of a cube = 10cm
Length, l = 12.5 cm
Breadth, b = 10cm
Height, h = 8 cm
Find out
We have to find
i) Which box has the greater lateral surface area and by how much?
ii) Which box has the smaller total surface area and by how much?
Solution
(i)
Lateral surface area of a cube = 4 * (edge)2
= 4 * 102 cm2
= 400 cm2
Lateral surface area of a cuboid = 2 (lh + bh)
= 2 (12.5 * 8 + 10 * 8) cm2
= 2 (100 + 80) cm2
= 360 cm2
So, the lateral surface area of the cubical box is greater than cuboidal box by (400 cm2 – 360 cm2) which is 40 cm2.
(ii)
Total surface area of a cube = 6 * (edge)2
= 6 * 102 cm2
= 600 cm2
Total surface area of cuboid = 2 (lb + bh + lh)
= 2 (12.5 * 10 + 10 * 8 + 12.5 * 8) cm2
= 2 (125 + 80 + 100) cm2
= 610 cm2
Therefore, the total surface area of the cuboidal box is greater than the cubical box by (610 cm2 – 600 cm2) which is 10 cm2.
If mary has to double the size of her garden and he garden is orginally 8 feet...all u do is double 8 which is 16!
Answer:15
Step-by-step explanation:
the ratio is 1:2 so 5 is half of 10 and if 10 becomes 30 it’s tripled so you would then have to triple 5 getting 15 , i hope this is right if not i’m sorry
