WARRIOR [948]

Answer:

144 cm²

Step-by-step explanation:

A prism's surface has 2 triangles & 3 rectangles.

In both the triangles , length of :

Perpendicular = 4 cm

Base = 6 cm

So , Area of both triangles = 2(\frac{1}{2} * Base * Perpendicular) = 2(\frac{1}{2}* 6 * 4) = 24 cm^2

In the 3 rectangles ,

Length = 8 cm

Width = 5 cm

So , Area of the rectangles = 3( Length * Width) = 3(8 * 5) = 120 cm^2

Hence the total surface area of the prism is = 120 + 24 =144 cm²

Two hot dogs and a soda cost $3.25.if three hot dogs and a soda cost $4.50.what is the cost of two sodas?
kotegsom [21]

Answer: $1.50

Step-by-step explanation: 1. subtract the 3.25 from 4.50 to get a difference that is the price of the added hotdog 2. now that you know each hot dog cost $1.25 you can do 3.25 - 2(1.25) to get 0.75 which is the price of one soda. 3. You can no multiply $0.75 by two (the amount of sodas) to get the answer $1.50.

Can you draw different functions that have the same x-intercepts and the same domain and range?
iogann1982 [59]
I'm pretty sure the answer is no.  A function looks like this: f(x) = mx + c.  Let's add another function, f(y) = ny + d.  If the x-intercept is the same, we can subtract c and d from their respective equations. f(x) = mx, f(y) = ny. If the domains are the same, then x and y can have the same value, so we divide it out. f(x) = m, f(y) = n.  Finally, if the ranges are the same, the value of f(x) = f(y).  So by the substitution property, m=n.  Since all the variables equal each other, both functions are equal to f(x) = mx+c!  Therefore, they can only be the same function.
