He has 20 guppies?
This is what I got from the information. Unless they had eggs.
First subtract the 2 dollars then you will have 6.39 then divid by the .99 wich gives you 6.45 which you round up to 7 copious because you can’t have a 1/2 of a copy
Answer: The value of x is 13 cm.
Explanation:
It is given that the length and width of the rectangle are 12 cm and 9 cm.
Use pythagoras to find the value of the diagonal.
![Hypotenuse=\sqrt{(base)^2+(perpendicular)^2}](https://tex.z-dn.net/?f=Hypotenuse%3D%5Csqrt%7B%28base%29%5E2%2B%28perpendicular%29%5E2%7D)
![D=\sqrt{(12)^2+(9)^2}](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B%2812%29%5E2%2B%289%29%5E2%7D)
![D=\sqrt{144+81}](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B144%2B81%7D)
![D=\sqrt{225}](https://tex.z-dn.net/?f=D%3D%5Csqrt%7B225%7D)
![D=15](https://tex.z-dn.net/?f=D%3D15)
It is given that the diagonal is labeled as 2x-11.
![2x-11=15](https://tex.z-dn.net/?f=2x-11%3D15)
![2x=15+11](https://tex.z-dn.net/?f=2x%3D15%2B11)
![2x=26](https://tex.z-dn.net/?f=2x%3D26)
Divide both side by 2.
![x=13](https://tex.z-dn.net/?f=x%3D13)
Therefore, x = 13cm.
Answer:
Answer D
Step-by-step explanation:
Triangle XYZ is rotated by a composition of 50°+40°=90° counter-clockwise. When a geometrical figure is rotated by any degree, then its shape or size does not change. A 90 degree rotation is a rotation by one quadrant, if you think of it on a coordinate plane. This inference should show you that choice D is the correct answer.
