Answer:
360 texts
Step-by-step explanation:
You get 15 points for each 3 texts.
That means you get 5 points per text.
1800/5 = 360
Answer: You need to send 360 texts.
This looks like an example of translation, where a figure is shifted, but not changed in size. Here's an example:
Answer:
0.218
Step-by-step explanation:
Well, firstly, that equations seems a bit strange. Let's use an equation I know a bit better: a^2 + b^2 = c^2. To clarify, '^2' means 'to the power of 2'. In this equation, 'c' represents the hypotenuse or the longest side of the angle. It is the only side that is diagonal. In this equation, we are given both the height and the length with the height being either 'a' or 'b' and the length being represented by 'c'. Using our formula, we would get this: 16^2 + b^2 = 20^2. To solve for 'b' which is representing our width, we would subtract '16^2' from both sides like so: b^2 = 20^2 - 16^2. From here, solve to get this: b^2 = 144. From here, square root both sides to get b = 12 or width = 12. Plug in your unit of measurement, feet (ft), and you have your answer!
Answer:
The surface area of the cylinder is ![\mathbf{70\pi\;\textbf{cm}^2}](https://tex.z-dn.net/?f=%5Cmathbf%7B70%5Cpi%5C%3B%5Ctextbf%7Bcm%7D%5E2%7D)
Step-by-step explanation:
The surface area of a cylinder is express
![S=2\pi rh](https://tex.z-dn.net/?f=S%3D2%5Cpi%20rh)
where
is the radius of the cylinder and
its height
Therefore, if the radius of the cylinder is
![r=5\;\text{cm}](https://tex.z-dn.net/?f=r%3D5%5C%3B%5Ctext%7Bcm%7D)
and its height
![h=7\;\text{cm}](https://tex.z-dn.net/?f=h%3D7%5C%3B%5Ctext%7Bcm%7D)
the surface area should be
![S=2\pi r h\\S=2\pi (5\;\text{cm})(7\;\text{cm}) \;\;\;\;\;\Rightarrow\;\;\;\;\; \mathbf{S=70\pi\;\textbf{cm}^2}](https://tex.z-dn.net/?f=S%3D2%5Cpi%20r%20h%5C%5CS%3D2%5Cpi%20%285%5C%3B%5Ctext%7Bcm%7D%29%287%5C%3B%5Ctext%7Bcm%7D%29%20%5C%3B%5C%3B%5C%3B%5C%3B%5C%3B%5CRightarrow%5C%3B%5C%3B%5C%3B%5C%3B%5C%3B%20%5Cmathbf%7BS%3D70%5Cpi%5C%3B%5Ctextbf%7Bcm%7D%5E2%7D)
